Aims. The aim of this study was to examine perioperative blood transfusion practice, and associations with clinical outcomes, in a national cohort of hip fracture patients. Methods. A retrospective cohort study was undertaken using linked data from the Scottish Hip Fracture Audit and the Scottish National Blood Transfusion Service between May 2016 and December 2020. All patients aged ≥ 50 years admitted to a Scottish hospital with a hip fracture were included. Assessment of the factors independently associated with red blood cell transfusion (RBCT) during admission was performed, alongside determination of the association between RBCT and hip fracture outcomes. Results. A total of 23,266 individual patient records from 18 hospitals were included. The overall rate of blood transfusion during admission was 28.7% (n = 6,685). There was inter-hospital variation in transfusion rate, ranging from 16.6% to 37.4%. Independent perioperative factors significantly associated with RBCT included older age (90 to 94 years, odds ratio (OR) 3.04 (95% confidence interval (CI) 2.28 to 4.04); p < 0.001), intramedullary fixation (OR 7.15 (95% CI 6.50 to 7.86); p < 0.001), and sliding hip screw constructs (OR 2.34 (95% CI 2.19 to 2.50); p < 0.001). Blood transfusion during admission was significantly associated with higher rates of 30-day mortality (OR 1.35 (95% CI 1.19 to 1.53); p < 0.001) and 60-day mortality (OR 1.54 (95% CI 1.43 to 1.67); p < 0.001), as well as delays to postoperative mobilization, higher likelihood of not returning to their home, and longer length of stay. Conclusion. Blood transfusion after hip fracture was common, although practice varied nationally. RBCT is associated with adverse outcomes, which is most likely a reflection of perioperative anaemia, rather than any causal effect. Use of RBCT does not appear to reverse this effect, highlighting the importance of perioperative blood loss reduction. Cite this article: Bone Joint J 2022;104-B(11):1266–1272

Aims. To evaluate if, for orthopaedic trainees, additional cadaveric simulation training or standard training alone yields superior radiological and clinical outcomes in patients undergoing dynamic hip screw (DHS) fixation or hemiarthroplasty for hip fracture. Methods. This was a preliminary, pragmatic, multicentre, parallel group randomized controlled trial in nine secondary and tertiary NHS hospitals in England. Researchers were blinded to group allocation. Overall, 40 trainees in the West Midlands were eligible: 33 agreed to take part and were randomized, five withdrew after randomization, 13 were allocated cadaveric training, and 15 were allocated standard training. The intervention was an additional two-day cadaveric simulation course. The control group received standard on-the-job training. Primary outcome was implant position on the postoperative radiograph: tip-apex distance (mm) (DHS) and leg length discrepancy (mm) (hemiarthroplasty). Secondary clinical outcomes were procedure time, length of hospital stay, acute postoperative complication rate, and 12-month mortality. Procedure-specific secondary outcomes were intraoperative radiation dose (for DHS) and postoperative blood transfusion requirement (hemiarthroplasty). Results. Eight female (29%) and 20 male trainees (71%), mean age 29.4 years, performed 317 DHS operations and 243 hemiarthroplasties during ten months of follow-up. Primary analysis was a random effect model with surgeon-level fixed effects of patient condition, patient age, and surgeon experience, with a random intercept for surgeon. Under the intention-to-treat principle, for hemiarthroplasty there was better implant position in favour of cadaveric training, measured by leg length discrepancy ≤ 10 mm (odds ratio (OR) 4.08 (95% confidence interval (CI) 1.17 to 14.22); p = 0.027). There were significantly fewer postoperative blood transfusions required in patients undergoing hemiarthroplasty by cadaveric-trained compared to standard-trained surgeons (OR 6.00 (95% CI 1.83 to 19.69); p = 0.003). For DHS, there was no significant between-group difference in implant position as measured by tip-apex distance ≤ 25 mm (OR 6.47 (95% CI 0.97 to 43.05); p = 0.053). No between-group differences were observed for any secondary clinical outcomes. Conclusion. Trainees randomized to additional cadaveric training performed hip fracture fixation with better implant positioning and fewer postoperative blood transfusions in hemiarthroplasty. This effect, which was previously unknown, may be a consequence of the intervention. Further study is required. Cite this article: Bone Jt Open 2023;4(8):602–611

Aims. Femoral periprosthetic fractures are rising in incidence. Their management is complex and carries a high associated mortality. Unlike native hip fractures, there are no guidelines advising on time to theatre in this group. We aim to determine whether delaying surgical intervention influences morbidity or mortality in femoral periprosthetic fractures. Methods. We identified all periprosthetic fractures around a hip or knee arthroplasty from our prospectively collated database between 2012 and 2021. Patients were categorized into early or delayed intervention based on time from admission to surgery (early = ≤ 36 hours, delayed > 36 hours). Patient demographics, existing implants, Unified Classification System fracture subtype, acute medical issues on admission, preoperative haemoglobin, blood transfusion requirement, and length of hospital stay were identified for all patients. Complication and mortality rates were compared between groups. Results. A total of 365 patients were identified: 140 in the early and 225 in the delayed intervention group. Mortality rate was 4.1% at 30 days and 19.2% at one year. There was some indication that those who had surgery within 36 hours had a higher mortality rate, but this did not reach statistical significance at 30 days (p = 0.078) or one year (p = 0.051). Univariate analysis demonstrated that age, preoperative haemoglobin, acute medical issue on admission, and the presence of postoperative complications influenced 30-day and one-year mortality. Using a multivariate model, age and preoperative haemoglobin were independently predictive factors for one-year mortality (odds ratio (OR) 1.071; p < 0.001 and OR 0.980; p = 0.020). There was no association between timing of surgery and postoperative complications. Postoperative complications were more likely with increasing age (OR 1.032; p = 0.001) and revision arthroplasty compared to internal fixation (OR 0.481; p = 0.001). Conclusion. While early intervention may be preferable to reduce prolonged immobilization, there is no evidence that delaying surgery beyond 36 hours increases mortality or complications in patients with a femoral periprosthetic fracture.

Purpose. To evaluate the effectiveness of the perioperative erythropoietin administration, as an alternative to homologous banked blood transfusions, in total hip arthroplasty. Material and Methods. In a prospective randomized, controlled study, 101 patients who underwent unilateral total hip replacement, during the period 2004–2009, were evaluated. In all these patients, the same surgical team applied the same surgical technique (hybrid THA) and they followed the same rehabilitation program. In 50 patients (group A or study group) we administered 40,000 units of erythropoietin subcutaneously one day before the operation followed by 40,000 units (sc) every 3 days in a total scheme of 4 doses. All these patients received intraoperatively one unit of homologous blood transfusion (1 unit/patient) and additional blood transfusions postoperatively when required. A control group of 51 patients (group B) received intraoperatively one or two units of homologous blood transfusion (1.35 units/patient), according to the volume of blood collected in the suction device and to the anaesthesiologists estimation, and also additional blood transfusions postoperatively when required. The admission of banked blood transfusion was determined by the haemoglobin value (< 9mg/dl) and/or clinical signs (blood pressure, pulse etc.). The values of haemoglobin, haematocrit and platelets were recorded preoperatively and the 1st, 5th, and 15th day postoperatively. Results. 15 patients of group A required postoperatively 15 units of homologous blood (total amount for group A 65 banked blood units 1.3 units/patient). 20 patients of group B required additional 26 banked blood units postoperatively (totally 95 banked blood units, or 1.86 units/patient). In the group A (study group), the total homologous blood requirements were reduced by 30%, the postoperative blood requirements were reduced by 42% and the number of patients that required additional blood transfusion was reduced by 25%. There was no significant difference in the postoperative haematocrit and haemoglobin values between the two groups. Conclusions. The perioperative use of erythropoietin reduces effectively the total demands of homologous banked blood transfusion in total hip arthroplasty

Background. In the literature are different data about the allogenic blood transfusion rate after total knee replacement. The common intention in orthopedic surgery is to reduce the requirement for allogenic blood transfusions by optimizing the blood management. The aim of this study is to determine the efficacy of the mechanical autotransfusion system OrthoPAT® to reduce the postoperative allogenic blood transfusion (ABT) rate. Method. According to the preliminary performed power analysis we did a prospective controlled study including 151 patients which were randomized in a group A (OrthoPAT® for intra- and postoperative blood salvage and retransfusion, n=76 patients) and a control group B (no retransfusion system was used, n=75 patients). All patients had a primary osteoarthritis of the knee and were operated on without use of a tourniquet. We implanted in all patients a cemented posterior stabilized total knee prosthesis design. In group A the autotransfusion system was used for 6 hours (intra- and postoperatively) and the collected blood was retransfused. The retransfused blood was anticoagulated, filtered and centrifuged to separate waste products. Red cells were washed with saline and reconcentrated to a high hematocrit. The preoperative data for cardiopathy, angiopathy, preoperative anemia or anticoagulant treatment showed no significant differences for group A and B. Because of missing data we finally were able to use the results of 140 patients: 70 group A and 70 in group B. The indications for a blood transfusion were influenced by the clinical symptoms of anemia, the hemoglobin value (hemoglobin < 8.0 g/dl) and the anamnesis of cardiovascular diseases. Evaluation was done with the medical history and the pre-/postoperative hemoglobin values and postoperative need of allogenic blood transfusion. Results. The two groups showed no significant differences relating to the demographic data or the medical history. 23 patients (33 %) of the retransfusion group who in mean received 281 ml of salvaged blood needed allogenic blood transfusion compared with 23 patients (33 %) of the control group B (p=0,999). The hemoglobin values of group A versus the control group showed after the donation of the salvaged blood a tendency to a higher hemoglobin value (p=0,062) but no longer at the third and fifth day postoperative. Conclusions. In this clinical observation the use of the autotransfusion system does not reduce the postoperative allogenic blood transfusion rate. At the third and fifth day postoperatively no significant differences of the hemoglobin values could be stated comparing group A with group B

Background. Tranexamic acid (TA) in total knee replacement surgery (TKR) has shown marked reduction in bleeding and blood transfusion. There are little data on TA in revision TKR. From February 2008 all patients having primary or revision TKR received TA 10mg/kg × 2. We whished to evaluate the effect and possible complications of TA. Patients and Methods. 49 patients had revision TKR from January to August 2010. 21 patients (group I) operated before the regular use of TA were compared to 28 patients (group II) receiving TA. The groups were compared according to bleeding, blood transfusion, postoperative complication and type of revision. Revision TKR was compared to 157 primary TKR (94 operated without TA (group III) and 63 who received TA (group IV). Results. Group I: Preoperative Hgl 13.6g/dl (9.2–15.3), reduction in hgl 3.9g/dl (1.0–5.7), bleeding 1040ml (380–2100). 6 patients (28.6%) needed blood transfusion. 7 patients were admitted to cell-saver and were given mean 400 ml blood (150–730). There were 6 revisions from uni-prostheses to TKR and 15 was revision of TKR. There was no difference in bleeding between this to groups (980ml/1030ml). Group II: Preoperative Hgl 14.2g/dl (11.2–18.6), reduction in hgl 3.3g/dl (1.4–8.3), bleeding 490ml (120–1050) (47.1% reduction in bleeding volume (p<0,002)). One patient (3.4%) needed blood transfusion. There was 8 revisions from uni-prostheses to TKR and 21 was revision of TKR. There was no difference in bleeding between this two groups (510ml/570ml). Group III: Preoperative Hgl 14.2g/dl (10.1–17.4), reduction in Hgl 3.5g/dl (1.1–7.7), bleeding 1048ml (50–2230). 15 patients (16%) needed blood transfusion. Group IV: Preoperative Hgl 13.7g/dl (11.6–18.1), reduction in Hgl 2.76g/dl (1.2–4.8) (p=0,014), bleeding 370ml (130–960) (64.5% reduction in volume (p<0,002)). 2 patients (3%) needed blood transfusion. (p=0,004)). There was no statistically significant difference in bleeding between primary and revision TKR (p=0.18). Conclusion. Our results shows that TA reduces bleeding and the need for blood transfusion markedly. The TA groups had no increase in any complications

Introduction. There is no established evidence to support the use of drains after total knee replacement; however 94% of orthopaedic surgeons in UK routinely use closed suction drains. Haematomas can form with or without using drains, presence of which in addition may provide portal for infection and may increase blood loss. Blood group and save is routinely performed for every patient undergoing total knee replacement, however actual cross match and transfusion is needed for a small percentage of patients. Aim. To compare the requirement for blood transfusion after total knee replacement with and without the use of closed suction drains and the cost analysis of performing routine blood group and save pre-operatively. Materials and Methods. In this retrospective study, we reviewed the data over the last 2 years (2008–2009). Patients were divided into 2 groups (drains versus no drains). 11 surgeons preferred drains and 2 did not use drains. We also compared the results of one particular surgeon who used drains for patients operated in the years 2006 and 2007 and did not use drains in the years 2008 and 2009. Results. 1564 knee replacements were performed by 13 surgeons. 8.1% patients (n=128) received blood transfusion post operatively. In the drainage group (n=1451), 8% patients (n=117) received transfusion. In the non-drainage group (n=113), 9.7% patients (n=11) received transfusion. Comparing the results of one particular surgeon (2006–2007), 5.7% patients (n=5) received transfusion (total n=87 with the use of drains) while 5.3% patients (n=3) operated by the same surgeon (2008–2009) had blood transfusion (total n=56 without using drains). As only 8.1% patients received blood transfusion, the blood samples for the remaining 91.9% patients remained unused. A single group and save sample currently costs £30.30. This suggests we could potentially save £21,750 per year by selectively performing group and save. Conclusion. There was no statistically significant difference in blood transfusion requirement in the two groups. In the current financially driven society, we can cut the costs significantly by selectively performing group and save and post operatively, if blood transfusion is indicated clinically, it can be arranged within safe time limit even in the absence of a pre-arranged sample

Aim. The aim of this prospective comparative study was to evaluate the serum levels of different cytokines in patients underwent total knee replacement (TKR) and received allogeneic blood transfusion, post-operative auto-transfusion or not transfused. Material and Methods. This was a prospective non-randomized comparative study in 248 patients underwent TKR. Patient's demographic and clinical data including age, gender, body mass index (BMI), preoperative Hb value, complications were documented. The serum levels of IL-1b, IL-6, IL-8, IL-10, and TNF were measure pre-operatively, the 1st, 2nd, 3rd and 5th post-operative day. Patients were categorized in three groups; in Group 0 patients received no blood transfusion, in Group 1 patients received post-operative auto-transfusion and in Group 2 allogeneic blood transfusion was applied. Statistical analysis of the results was performed using repeated measures ANOVA. Results. Significant changes were observed in cytokines levels in Groups 1 and 2. In Group 1 (auto-transfusion) the levels of all cytokines significantly increased the 1st postoperative day, remaining above the pre-operative levels even the 5th post-operative day. In Group 2 (allogenic transfusion), although the levels of IL-6, IL-8 and IL-10 were also significantly increased the 1st postoperative day, they gradually returned to the per-operative levels by the 5th post-operative day. In Group 0 (no transfusion) the only significant increase was observed in IL-6 between pre-operative and 1st and 3rd day values. Furthermore, the area under the curve (AUC) of IL-1b, IL-6, IL-8 and IL-10 levels in Group 1 and AUC of IL-6, IL-8 and IL-10 levels in Group 2, were significantly higher compared to Group 0. There was no significant difference in post-operative patient's complications. Conclusion. According to the results of this study significant elevation of cytokine values were observed during the first five post-operative days in patients received blood transfusion after TKR. These changes were more pronounced in the auto-transfusion group

About 81,000 total knee replacements are implanted in the United Kingdom annually. Conventionally pneumatic tourniquet and surgical drains have been used in total knee arthroplasty. However, no definite evidence or guidelines exist to support their use. The present study aims to look for any difference in perioperative recovery and complications following use of pneumatic tourniquet and surgical drains in knee replacement surgery. We retrospectively analysed 60 total knee arthroplasties performed by 3 different surgeons at our hospital during January 2007 to June 2010. A sample size of 20 patients in each group was evaluated. Group 1: used tourniquet and drain; Group 2: used tourniquet but no drain; Group 3: didn't use tourniquet but used drain. Data was collected and analysed using statistical means, t-test & analysis of variance. Parameters compared were surgical (anaesthetic) time, mean postoperative haemoglobin at 24 hrs, blood transfusion rate, haematoma formation, wound infection, pain, deep vein thrombosis and infection at discharge. At 6 weeks clinical follow up letters were analysed. Our results reveal that there is no significant difference in duration of surgery in either group. Use of tourniquets didn't improve on surgical time (123–133 minutes). Our Local Hospital Pain Score was used (1 no pain, 2 mild, 3 moderate, 4 severe and 5 worst imaginable pain). No difference at discharge was seen in either group. Similarly no difference was seen in either group with postoperative haematoma formation with one case (5%) in Group 1 and 3 respectively. Although the immediate postoperative haemoglobin (Hb%) was comparable in all 3 groups, Group 3 patients received more blood transfusion compared to other groups based on clinical grounds. About 50 % of Group 3 needed blood transfusion compared to 10% in Group 1 and 5% in Group 2. There was only one proven case of superficial infection at 6 weeks (Group 2) which responded well to antibiotics. There were 4 cases of cellulitis noted at 6 weeks (3 in Group 2 and 1 in Group 3) which responded to oral antibiotics. No deep infection was noted. The mean hospital stay in hospital was 6.5 days in Group 1, 5.5 days in Group 2 and 8 days in Group 3. There was no difference in rate of post-operative deep vein thrombosis (5% in Group 1 and 3). The present study with the use of tourniquet and surgical drain in total knee arthroplasty showed no significant difference in surgical time and incidence of postoperative haematoma, deep vein thrombosis. Pain score at discharge was comparable and so was the infection rate. Patients in Group 2 (used tourniquet but no surgical drain) had least hospital stay (mean 5.5 days) and least blood transfusion rate (5%). Decision to use pneumatic tourniquet & drain still lies with the operating surgeon. We recommend a randomised control study for further evidence

Aim. There is not adequate evidence to establish whether external fixation (EF) of pelvic fractures leads to a reduced mortality. We used the Japan Trauma Data Bank database to identify isolated unstable pelvic ring fractures to exclude the possibility of blood loss from other injuries, and analyzed the effectiveness of EF on mortality in this group of patients. Patients and Methods. This was a registry-based comparison of 1163 patients who had been treated for an isolated unstable pelvic ring fracture with (386 patients) or without (777 patients) EF. An isolated pelvic ring fracture was defined by an Abbreviated Injury Score (AIS) for other injuries of < 3. An unstable pelvic ring fracture was defined as having an AIS ≥ 4. The primary outcome of this study was mortality. A subgroup analysis was carried out for patients who required blood transfusion within 24 hours of arrival in the Emergency Department and those who had massive blood loss (AIS code: 852610.5). Propensity-score matching was used to identify a cohort like the EF and non-EF groups. Results. With the use of propensity-score matching using the completed data, 346 patients were matched. When the propensity-score matching was adjusted, EF was associated with a significantly lower risk of death (p = 0.047). In the subgroup analysis of patients who needed blood transfusion within 24 hours and those who had massive blood loss, EF was associated with a significantly lower risk of death in patients who needed blood transfusion within 24 hours (p = 0.014) and in those with massive blood loss (p = 0.016). Conclusion. The use of EF to treat unstable pelvic ring fractures was associated with a significantly lower risk of death, especially in patients with severe fractures.

Purpose. To evaluate the long term results of the use of a postoperative autologous blood reinfusion system in total knee arthroplasty. Material and method. In a prospective study, 176 patients who underwent unilateral total knee replacement, during the period 2004–2008, were evaluated (study group or group A). In all these patients a reinfusion system of unwashed blood salvaged was applied, while supplementary homologous blood transfusion was performed when required. The admission of banked blood transfusion determined by haemoglobin value (<9mg/dL) and/or clinical signs (blood pressure, pulses, etc). The value of haemoglobin, haematocrite and platelets recorded preoperatively and the 1st, 5th and 15th day after operation. Results were compared with the material of our previous prospective randomized controlled study (control groups B and C), where in 60 patients, between the years 2002–2004, the effectiveness of postoperative autologous blood reinfusion had been proved. Results. 19 patients of group A required postoperatively 23 units of homologous blood (total study group requirements23 blood units or 0.13 units per patient) while in group B required 1.5 units/patient and in group C 0.3 units/patient. In the study group the total homologous blood requirements reduced by 91% compared with group B (patients without autotransfusion system applied) and by 47% compared with group C (patients with autotransfusion system applied). There was no statistically significant difference in the postoperative values of Hb and Ht between the groups. None of the patients developed any adverse reactions after reinfusion. The cost of blood management was reduced in study group by 76%. Conclusions. The use of an autotransfusion system postoperatively minimizes practically the demands for homologous banked blood transfusion in total knee arthroplasty

AIM. Retrospective study comparing the effectiveness of preoperative autologous blood donation versus intra-operative blood saver systems in minimizing the need for allogeneic blood transfusion in scoliosis surgery. MATERIALS – METHODS. Between 2003–2009, 37 of the patients (4–33, mean age 20y) who underwent scoliosis surgery, were divided in two groups. The first group (20 patients, mean age 18.7y) underwent autologous blood predonation, prerequisities were body weight over 50 kgr and Hgb above 11 mg/dl. The second group (17 patients, mean age 21.5y) consisted of patients who did not meet the above prerequisities and blood saver was used intra-operatively. Duration of surgery and perioperative Haemoglobulin (Hgb) levels were recorded in both groups. RESULTS. In group A an average of 4 autologous blood units per patient were predonated (3–5 units/patient) and the mean transfusion rate was 3.4 autologous blood units/patient. Only one patient was transfused with one allogeneic blood unit while of the 81 predeposited autologous blood units 15 were wasted (18.5%). In Group B intra-operative autotransfusion systems salvaged 302.9 ml/patient (150–500 ml/patient) while the mean transfusion rate was 2.1 allogeneic blood units/patient. CONCLUSIONS. The use of intra-operative autotransfusion systems seems to reduce the need for allogeneic blood transfusion when compared with preoperative autologous blood donation. However, the lower preoperative Hgb in Group B have to be taken under consideration. Further studies need to prove the effectiveness of these methods so that perioperative blood management minimizes the need for allogeneic blood transfusion in scoliosis surgery

Introduction. Tranexamic acid is an inhibitor of fibrinolysis that blocks the lysine-binding site of plasminogen to fibrin, and thereby decreases blood loss in patients undergoing surgery. Aims and objectives. A prospective, randomized, double-blind study was done on 100 patients undergoing primary cemented Unilateral Total Knee Arthroplasty to determine the effect of tranexamic acid on intra- and postoperative blood losses and on the transfusions requirements. Material and Methods. 100 patients undergoing unilateral cemented total knee Arthroplasty for osteoarthritis were enrolled for the study. All total knee replacement was done under combined spinal epidural anaesthesia with the use of tourniquet. 100 patients were randomized to tranexamic acid (15 mg/kg) given as a bolus intravenous injection or placebo (normal saline) given intravenously, 15 minutes before the release of tourniquiet. The blood loss (at removal of the drain 24 hours after the operation) and the number of blood transfusions required were recorded. The patients were screened for deep venous thrombosis with bilateral compression Ultrasonography using Colour Doppler imaging on the tenth postoperative day. The Hemoglobin level was measured preoperatively and on the 3rd postoperative day. The D-dimer levels were measured preoperatively and 24 hrs postoperatively. Results. Patients receiving tranexamic acid had a mean postoperative blood loss of 175 ml(range, 130–310ml) versus 330 ml (range, 210–460ml) (p value<0.05), and a total need for 3 blood transfusions versus 15. Only 3 out 50 patients in tranexamic acid group required blood transfusion whereas 12 out of 50 patients in the placebo group required transfusion. In the group receiving placebo the mean fall in hemoglobin was 2.1g/dl (range, 1.5–3.2) and in the group treated with tranexamic acid 1.3 g/dl (0.9–2) (p<0.05). At 24 hrs postoperatively, mean plasma D-dimer concentration in the Tranexamic group was half of that in the control group. No patient in either group had any evidence of deep vein thrombosis on bilateral compression Ultrasonography using Colour Doppler imaging done on the tenth postoperative day. Conclusion. Tranexamic acid 15 mg/kg given as a single bolus dose reduces blood loss, and transfusion requirements in unilateral primary cemented total kneearthroplasty without any increased risk of thrombus formation

Aims. To compare the outcomes for trochanteric fractures treated with a sliding hip screw (SHS) or a cephalomedullary nail. Patients and Methods. A total of 400 patients with a trochanteric hip fracture were randomised to receive a SHS or a cephalomedullary nail (Targon PFT). All surviving patients were followed up to one year from injury. Functional outcome was assessed by a research nurse blinded to the implant used. Results. Recovery of mobility, as assessed by a mobility scale, was superior for those treated with the intramedullary nail compared with the SHS at eight weeks, three and nine months (p-values between 0.01 and 0.04), the difference at six and 12 months was not statistically significant (p = 0.15 and p = 0.18 respectively). The mean difference was around 0.4 points (0.3 to 0.5) on a nine point scale. Surgical time for the nail was four minutes less than that for the SHS (p < 0.001). Fracture healing complications were similar for the two groups. There were no statistically significant differences between implants for any other recorded outcomes including the need for post-operative blood transfusion, wound healing complications, general medical complications, hospital stay or mortality. Conclusion. This study confirms the findings of a previous study that both methods of treatment produce similar results, although intramedullary fixation does result in marginally improved regain of mobility in comparison with the SHS.

Tranexamic Acid (TA) has been shown to reduce transfusion rates in Total Knee Replacement (TKR) without complication. In our unit it was added to our routine enhanced recovery protocol. No other changes were made to the protocol at this time and as such we sought to examine the effects of TA on wound complication and transfusion rate. All patients undergoing primary TKR over a 12 month period were identified. Notes and online records were reviewed to collate demographics, length of stay, use of TA, thromboprophylaxis, blood transfusion, wound complications and haemoglobin levels. All patients received a Columbus navigated TKR with a tourniquet. Only patients who received 14 days of Dalteparin for thromboprophylaxis were included. 124 patients were included, 72 receiving TA and 52 not. Mean age was 70. Four patients required a blood transfusion all of whom did not receive TA (p = 0.029). Mean change in Hb was 22 without TA and 21 with (p = 0.859). Mean length of stay was 6.83 days without Tranexamic Acid and 5.15 with (p < 0.001). 15% of patients (n=11) of the TA group had a wound complication, with 40% of patients (n=21) in the non TA group (p = 0.003). There was one ultrasound confirmed DVT (non TA group). No patients were diagnosed with pulmonary embolus. In our unit we have demonstrated a significantly lower transfusion rate, wound complication rate and length of stay, without any significant increase in thromboembolic disease with the use of TA in TKR

Rivaroxiban is a factor Xa inhibitor and is a newer oral alternative for thromboprophylaxis after joint replacements. Its major advantage is its oral administration and hence better patient compliance. However there are some doubts about its efficacy compared to dalteparin/heparin. We have recently changed over from using dalteparin injections to rivaroxiban tablets for thromboprophylaxis after hip replacements. We assessed our results to find efficacy and specificity of its action in patients undergoing THR. 504 patients underwent hip replacement in last 2 years. 316 were treated with dalteparin injections (fragmin) for thromboprophylaxis while 189 patients were treated with oral rivaroxiban for 35 days after their hip replacement. Average haemoglobin drop at 24 hours postop was 2.79 in Rivaroxiban group compared to 3. 10 in dalteparin group. 19 patients (of 189 i.e. 10.05%) required postop blood transfusion in rivaroxiban group as against 60 (of 315 i.e. 19.04%) in Dalteparin group. This difference was statistically significant. Incidence of DVT was no different in either groups, but the number of patients was too small to compare this. Rivaroxiban appears to be more specific in its action and our results suggest a significant reduction in postop blood transfusion following hip replacements without any increase in rate of Deep Vein Thrombosis. We would like to present our findings and discuss role of oral thromboprophylaxis after joint replacements

Primary total hip replacement (THR) surgery is a common procedure. Benchmarking studies in the last decade has shown that those patients have a substantial risk for blood transfusions. The orthopaedic department at Drammen Hospital had implemented a multimodal primary THR care pathway with a focus on minimising surgical trauma and negative trauma response. Neither blood salvage, autologuos blood predonation or erythropoietin has been used. We had reviewed 399 consecutive unselected cases with a mean age of 67 years (range 31–94). We performed a statistic analysis of pre- and postoperative haemoglobin level (g/l). A gender neutral 125 was used as cut point for anaemia. Preoperative haemoglobin level, mean 136 (SD 1.33), and postoperative haemoglobin, mean 113 (SD 1.41), showed an almost perfect Gaussian distribution. Eleven patients received 26 units of allogeneic blood in the first eight postoperative days. There had been a violation of transfusion policy in six of the eleven transfused patients. Mortality during the first 90 postoperative days was zero and 4 patients was readmitted due to cardiac disease during the first 90 postoperative days. All those readmitted due to cardiac disease had an haemoglobin level above 100 at discharge. By combining the Gaussian distribution of the postoperative haemoglobin level and a restrictive transfusion trigger (80 g/l), we calculated a two percent probability of transfusion. For the anaemic patients the calculated probability of transfusion were five percent. Applying a multimodal care pathway in primary THR almost abolish the need for blood transfusion without any preconditioning of anaemic patients. This study supports that an restrictive transfusion trigger are safe in an unselected total hip replacement patient population

Objectives. To determine the morbidity and mortality outcomes of patients presenting with a fractured neck of femur in an Australian context. Peri-operative variables related to unfavourable outcomes were identified to allow planning of intervention strategies for improving peri-operative care. Methods. We performed a retrospective observational study of 185 consecutive adult patients admitted to an Australian metropolitan teaching hospital with fractured neck of femur between 2009 and 2010. The main outcome measures were 30-day and one-year mortality rates, major complications and factors influencing mortality. . Results. The majority of patients were elderly, female and had multiple comorbidities. Multiple peri-operative medical complications were observed, including pre-operative hypoxia (17%), post-operative delirium (25%), anaemia requiring blood transfusion (28%), representation within 30 days of discharge (18%), congestive cardiac failure (14%), acute renal impairment (12%) and myocardial infarction (4%). Mortality rates were 8.1% at 30 days and 21.6% at one year. Factors predictive of one-year mortality were American Society of Anesthesiologists (ASA) score (odds ratio (OR) 4.2 (95% confidence interval (CI) 1.5 to 12.2)), general anaesthesia (OR 3.1 (95% CI 1.1 to 8.5)), age > 90 years (OR 4.5 (95% CI 1.5 to 13.1)) and post-operative oliguria (OR 3.6 (95% CI 1.1 to 11.7)). Conclusions. Results from an Australian metropolitan teaching hospital confirm the persistently high morbidity and mortality in patients presenting with a fractured neck of femur. Efforts should be aimed at medically optimising patients pre-operatively and correction of pre-operative hypoxia. This study provides planning data for future interventional studies.

In a randomised trial involving 598 patients with 600 trochanteric fractures of the hip, the fractures were treated with either a sliding hip screw (n = 300) or a Targon PF intramedullary nail (n = 300). The mean age of the patients was 82 years (26 to 104). All surviving patients were reviewed at one year with functional outcome assessed by a research nurse blinded to the treatment used. The intramedullary nail was found to have a slightly increased mean operative time (46 minutes (. sd. 12.3) versus 49 minutes (. sd. 12.7), p < 0.001) and an increased mean radiological screening time (0.3 minutes (. sd. 0.2) versus 0.5 minutes (. sd. 0.3), p <  0.001). Operative difficulties were more common with the intramedullary nail. There was no statistically significant difference between implants for wound healing complications (p = 1), or need for post-operative blood transfusion (p = 1), and medical complications were similarly distributed in both groups. There was a tendency to fewer revisions of fixation or conversion to an arthroplasty in the nail group, although the difference was not statistically significant (nine versus three cases, p = 0.14). The extent of shortening, loss of hip flexion, mortality and degree of residual pain were similar in both groups. The recovery of mobility was superior for those treated with the intramedullary nails (p = 0.01 at one year from injury). In summary, both implants produced comparable results but there was a tendency to better return of mobility for those treated with the intramedullary nail

We compared the outcome of patients treated for an intertrochanteric fracture of the femoral neck with a locked, long intramedullary nail with those treated with a dynamic hip screw (DHS) in a prospective randomised study. Each patient who presented with an extra-capsular hip fracture was randomised to operative stabilisation with either a long intramedullary Holland nail or a DHS. We treated 92 patients with a Holland nail and 98 with a DHS. Pre-operative variables included the Mini Mental test score, patient mobility, fracture pattern and American Society of Anesthesiologists grading. Peri-operative variables were anaesthetic time, operating time, radiation time and blood loss. Post-operative variables were time to mobilising with a frame, wound infection, time to discharge, time to fracture union, and mortality. We found no significant difference in the pre-operative variables. The mean anaesthetic and operation times were shorter in the DHS group than in the Holland nail group (29.7 vs 40.4 minutes, p < 0.001; and 40.3 vs 54 minutes, p < 0.001, respectively). There was an increased mean blood loss within the DHS group versus the Holland nail group (160 ml vs 78 ml, respectively, p < 0.001). The mean time to mobilisation with a frame was shorter in the Holland nail group (DHS 4.3 days, Holland nail 3.6 days, p = 0.012). More patients needed a post-operative blood transfusion in the DHS group (23 vs seven, p = 0.003) and the mean radiation time was shorter in this group (DHS 0.9 minutes vs Holland nail 1.56 minutes, p < 0.001). The screw of the DHS cut out in two patients, one of whom underwent revision to a Holland nail. There were no revisions in the Holland nail group. All fractures in both groups were united when followed up after one year. We conclude that the DHS can be implanted more quickly and with less exposure to radiation than the Holland nail. However, the resultant blood loss and need for transfusion is greater. The Holland nail allows patients to mobilise faster and to a greater extent. We have therefore adopted the Holland nail as our preferred method of treating intertrochanteric fractures of the hip
