Aims. Factors associated with high mortality rates in geriatric hip fracture patients are frequently unmodifiable. Time to surgery, however, might be a modifiable factor of interest to optimize clinical outcomes after hip fracture surgery. This study aims to determine the influence of postponement of surgery due to non-medical reasons on clinical outcomes in acute hip fracture surgery. Methods. This observational cohort study enrolled consecutively admitted patients with a proximal femoral fracture, for which surgery was performed between 1 January 2018 and 11 January 2021 in two level II trauma teaching hospitals. Patients with medical indications to postpone surgery were excluded. A total of 1,803 patients were included, of whom 1,428 had surgery < 24 hours and 375 had surgery ≥ 24 hours after admission. Results. Prolonged total length of stay was found when surgery was performed ≥ 24 hours (median 6 days (interquartile range (IQR) 4 to 9) vs 7 days (IQR 5 to 10); p = 0.001) after admission. No differences in postoperative length of hospital stay nor in 30-day mortality rates were found. In subgroup analysis for time frames of 12 hours each, pressure sores and urinary tract infections were diagnosed more frequently when time to surgery increased. Conclusion. Longer time to surgery due to non-medical reasons was associated with a higher incidence of postoperative pressure sores and urinary tract infections when time to surgery was more than 48 hours after admission. No association was found between time to surgery and 30-day mortality rates or postoperative length of hospital stay. Cite this article: Bone Joint J 2022;104-B(12):1369–1378

The objectives of our study were to compare patient reported outcome measures between manual and robotic-assisted total hip arthroplasty.

Between 1st May 2021 and 31st August 2022, 539 consecutive patients who underwent 564 primary total hip arthroplasties were identified from the local registry database. Data were prospectively collected, and included patient demographics, American Society of Anaesthesiologists (ASA) grade, surgical approach, robotic-assistance, Oxford Hip Score (OHS), EQ-5D-3L and EQ-VAS pre-operatively and at twelve months.

Robotic-assistance, compared against manual total hip arthroplasty, was associated with an enhanced median (interquartile range) OHS (46 [42 – 48] vs 43 [36 – 47], p-value < 0.001), EQ-5D-3L (5 [5 – 7] vs 6 [5 – 8], p-value 0.002), and EQVAS (90 [75 – 95] vs 80 [70 – 90], p-value 0.003) at twelve months after surgery. Robotic-assistance was confirmed to be an independent predictor of a greater OHS at twelve months on a multivariate linear regression analysis (p-value 0.001).

Robotic assistance was superior to manual total hip arthroplasty in enhancing patient reported outcomes at twelve months after surgery.

The aim of this study was to evaluate the long-term outcomes of patients who had sustained an unstable ankle fracture with a posterior malleolus fracture (PMF) and without (N-PMF).

Adult patients presenting to a single academic trauma centre in Edinburgh, UK, between 2009 and 2012 with an unstable ankle fracture requiring surgery were identified. The primary outcome measure was the Olerud Molander Ankle Score (OMAS). Secondary measures included Euroqol-5D-3L Index (Eq5D3L), Euroqol-5D-VAS and Manchester Oxford Foot Questionnaire (MOXFQ).

There were 304 patients in the study cohort. The mean age was 49.6 years (16.3–78.3) and 33% (n=100) male and 67% (n=204) female. Of these, 67% (n=204) had a PMF and 33% did not (n=100). No patient received a computed tomography (CT) scan pre-operatively. Only 10% of PMFs (22/204) were managed with internal fixation. At a mean of 13.8 years (11.3 – 15.3) the median OMAS score was 85 (Interquartile Range 60 – 100). There was no difference in OMAS between the N-PMF and PMF groups (85 [56.25 – 100] vs 85 [61.25 – 100]; p = 0.580). There was also no difference for MOXFQ (N-PMF 7 [0 – 36.75] vs PMF 8 [0–38.75]; p = 0.643), the EQ5D Index (N-PMF 0.8 [0.7 – 1] vs PMF 0.8 [0.7 – 1]; p = 0.720) and EQ5D VAS (N-PMF 80 [70 – 90] vs PMF 80 [60 – 90]; p = 0.224).

The presence of a PMF does not affect the long-term patient reported outcomes in patients with a surgically managed unstable ankle fracture.

Background:. The aim of this study was to review the surgical complications and clinical outcomes of patients with Pilon fractures treated with Ilizarov frames. Methods:. Data collected included surgical complications, grade of initial injury using the Ruedi-Allgower classification and quality of reduction according to the Teeny and Wiss criteria. Outcome scores were collected retrospectively using the Foot and Ankle Disability Index (FADI). Results:. A total of 97 consecutive patients were identified. All patients were treated with indirect reduction by capsuloligamentotaxis and stabilisation using an ankle-spanning Ilizarov external fixator. The mean time to union was 6 months. Data was available for 70 patients. 35 patients developed a pin site infection. There were no cases of osteomyelitis. 4 patients developed a DVT and 1 patient a PE, 4 patients required ankle fusions. Quality of reduction according to the criteria of Teeny and Wiss was anatomic in 40 patients, good in 23 patients, fair in 6 patients, poor in 3 patients. Conclusion:. This is one of the larger series of Pilon factures on literature review. Ilizarov frame fixation achieves stable reduction of the fractured fragments without additional trauma to soft tissues with minimal complications and good functional results

The aims of this study in relation to distal radius fractures were to determine (1) the floor and ceiling effects for the QuickDASH and PRWE, (2) the floor and ceiling effects when defined to be within the minimal clinically important difference (MCID) of the minimal or maximal scores, (3) the degree to which patients with a floor or ceiling effect felt that their wrist was ‘normal’, and (4) patent factors associated with a floor or ceiling effect.

A retrospective cohort study of patients sustaining a distal radius fracture during a single year was undertaken. Outcome measures included the QuickDASH, PRWE, EQ-5D-3L and normal wrist score.

There were 526 patients with a mean age of 65yrs and 77% were female. Most patients were managed non-operatively (73%, n=385). The mean follow-up was 4.8yrs. A ceiling effect was observed for both the QuickDASH (22.3%) and PRWE (28.5%). When defined to be within the MCID of the best score, the effect increased to 62.8% for the QuickDASH and 60% for PRWE. Patients that achieved the best functional outcome according to the QuickDASH and PRWE felt their wrist was only 91% and 92% normal, respectively. Sex (p=0.000), age (p=0.000), dominant wrist injury (p=0.006 for QuickDASH and p=0.038 for PRWE), fracture type (p=0.015), and a better health-related quality of life (p=0.000) were independently associated with achieving a ceiling score.

The QuickDASH and PRWE demonstrated ceiling effects following a distal radius fracture. Patients achieving ceiling scores did not consider their wrist to be ‘normal’ for them.

Objective. To compare regional body composition, bone mineral density (BMD), and clinical outcome in patients with two different shoulder arthroplasty designs. Materials and Methods. This cross-sectional study included 54 patients with a total of 63 shoulder arthroplasties. There were 18 men and 45 women with a mean age of 68.9 years SD ± 10.5. Mean follow-up time was 39.2 months SD ± 14.4. The patients were divided into three groups according to their history: 22 patients were diagnosed with a proximal humeral fracture and treated with a stemmed hemi arthroplasty, 11 patients were diagnosed with osteoarthritis and treated with a stemmed hemi arthroplasty, and 30 patients were diagnosed with osteoarthritis and treated with a resurfacing arthroplasty. All patients underwent a one-day protocol: Regional Dual X-ray Absorptiometri (DXA) was used to measure BMD of the distal third of humerus and regional body composition of the upper arm. The clinical outcome was measured using Western Ontario Osteoarthritis of the Shoulder index (WOOS) and Constant-Murley score. Results. All three groups were comparable regarding demographic data. Mean BMD of the distal third of humerus was 1.029 g/cm2 SD ± 0.204, mean tissue mass of the upper arm was 2.6 kg SD ± 0.7 and mean muscle mass was 1.4 kg SD ± 0.6. BMD of the distal third of humerus, tissue mass and muscle mass were significantly higher in the group diagnosed with osteoarthritis and treated with a resurfacing arthroplasty compared to the group diagnosed with a proximal humeral fracture and treated with a stemmed hemi arthroplasty, P = 0.03, P = 0.01 and P = 0.02 respectively. Median Constant score was 45.0, range 6–89, median WOOS 633, range 28–1824, and median strength 7.0 units, range 0–25. There were no significant differences between the three groups. Nevertheless, there was a trend towards a higher Constant-Murley score and muscle strength in the group of patients diagnosed with osteoarthritis and treated with a resurfacing arthroplasty compared to the group of patients diagnosed with a proximal humeral fracture and treated with a stemmed hemi arthroplasty. Conclusion. After shoulder arthroplasty BMD of the distal third of humerus and body composition are apparently more dependent on diagnosis rather than arthroplasty design. However, a larger number of patients diagnosed with osteoarthritis and treated with a stemmed hemi arthroplasty are needed to support this

Objective. To describe demographic data, clinical outcome and short-term survival after shoulder arthroplasty. Materials and Methods. The Danish Shoulder Arthroplasty Register was established in 2004. All 40 Danish hospitals and private clinics where shoulder arthroplasty are performed are participating. Since 2006 where the reporting to the register became mandatory the compliance of reporting has been 88.9%. Data are collected by an internet based clinical measuring system where the orthopaedic surgeon report data such as diagnosis, type of arthroplasty, and demographic data. The follow-up results are collected by sending a questionnaire to the patient 10–14 month after the operation. The questionnaire contains a Western Ontario Osteoarthritis of the Shoulder index (WOOS). Each question is answered on a visual analogue scale with a possible score ranging from 0–100. There are 19 questions and the total score is ranging from 0–1900. For simplicity of presentation the raw scores is converted to a percentage of a normal shoulder. Results. 2320 Shoulder arthroplasties were reported to the register between 2006 and 2008. There were 69.4% women. Median age was 70.6, range 16.3–96.3. 699 arthroplasties (30.0%) were due to osteoarthritis, 98 (4.2%) due to arthritis, 1182 (50.9%) due to a proximal humeral fracture, 179 (7.4%) due to rotator cuff arthropaty, 62 (2.7%) due to caput necrosis and 79 (3.4%) due to other pathology condition such as cancer and revision surgery. 1352 (58.3%) were stemmed hemi arthroplasty, 77 (3.3%) total shoulder arthroplasty, 596 (25.7%) resurfacing arthroplasty and 243 (10.5%) reverse shoulder arthroplasty. 1288 patients (55.5%) returned a complete questionnaire. Median WOOS for all arthroplasties was 58.2, range 0.0–100.0. Median WOOS for arthritis was 59.3, range 13.3–99.8, osteoarthritis 67.9, range 0.0–100.0, a proximal humeral fracture 54.2, range 0.0–100.0, rotator cuff arthropaty 65.6, range 0.0–98.3 and caput necrosis 48.9, range 3.9–95.2. 171 (7.4%) operations were revisions. The most common indications of revision were luxation (2.2%), infection (1.3%), loosening (0.7%) and glenoid attrition (0.6%). Conclusion. To our knowledge there is no previous study with such a large population presenting demographic data and clinical outcome after shoulder arthroplasty. We found good results for the groups of patients diagnosed with osteoarthritis, arthritis and cuff arthropaty. There were poorer results in the groups of patient diagnosed with a proximal humeral fracture and especially caput necrosis

Objective. To provide a best estimate of the average treatment effect when microfracture was chosen as the intervention of choice in patients with full-thickness cartilage defects of the knee. Design. We focussed on controlled studies which either referred to microfracture alone or in comparison with any other surgical treatment of articular cartilage of the knee. Papers including patients who had been treated by microfracture and concomitant adjuvant procedures like ACL reconstruction or meniscus repair were accepted too, whereas papers reporting on the microfracture technique combined with the implantation of a scaffold were excluded. To achieve a best estimate of the average, to be expected treatment effect we pooled pooled before–after data of study arms using microfracture. Because cartilage studies employ various scales to measure functional improvements, we standardized treatment effects using Hedges' g. To provide clinically meaningful estimates we converted the pooled summary effect back into the respective scales by multiplying the pooled effect with pooled standard deviations of each included clinical scale. Results. A systematic review of the literature revealed six papers including 200 patients with a mean age of 32 years, a mean defect size of 3 cm. 2. and a follow up period from 2 to 5 years. Four of the studies compared microfracture to autologous chondrocyte implantation and two of them to osteochondral autologous transplantation. All patients were treated by the microfracture technique as described by Steadman and by a similar rehabilitation protocol which only allowed crutch-assisted touchdown weight bearing initially. Referring to the individual studies, a comparison of the pooled estimates of Hedges' g revealed that the two papers which evaluated the youngest patients provided the highest treatment effect. On the contrary, those two papers which focussed on the largest lesions, reported the worst improvement. Finally, the remaining two papers whose patients were characterized by similar age and defect size presented comparable results. The individual standardized effect sizes were combined into an overall best estimate. Its value was 1.678, measured in units of standard deviation, with the 95% confidence interval of [1.016; 2.340] resulting in different values of the average, to be expected treatment effect when it is measured in Lysholm Score (22.1), IKDC Score (26.5) and KOOS (15.2) points. Conclusions. Our results offer a clinically intuitive estimation of the average treatment effects on common clinical scales. Compared to the preoperative situation, a significant clinical improvement can be expected for each patient. Nevertheless, the magnitudes of these treatment effects are an approximation and must be interpreted cautiously. Furthermore, we did not succeed to confirm that young age and small lesion size have a beneficial effect on the clinical outcome

Introduction. Undisplaced femoral neck fractures have been given little attention in the literature. By using data from the Norwegian Hip Fracture Register, this study investigates risk for reoperation and the clinical results, including pain, patient satisfaction, and quality of life, after undisplaced femoral neck fractures in elderly patients. Material and Methods. Data on 4,468 patients over 70 years of age with undisplaced femoral neck fractures operated with internal fixation (IF) were compared to 10,289 patients with displaced femoral neck fractures treated with IF (n = 3,389) or bipolar hemiarthroplasty (n = 6,900). The evaluation was based on number of reported reoperations and patients' assessment (visual analogue scales concerning pain (0–100) and patient satisfaction (0–100), and quality of life (EQ-5D)) four and twelve months postoperatively. The patients were followed for 0–1 year. The Cox multiple regression model was used to construct adjusted survival curves. Subanalyses were performed on undisplaced femoral neck fractures to investigate different risk factors for reoperation. Results. The survival rate of implants after one year was 89% after screw fixation for undisplaced fractures, 79% after screw fixation for displaced fractures, and 97% after hemiarthroplasty for displaced fractures (Kaplan Meier). Adjusted for age, sex, ASA-classification, and cognitive function the displaced fractures operated with internal fixation had higher risk of reoperation compared to the undisplaced fractures operated with internal fixation (RR 1.92, 95% CI: 1.69–2.17; p<0.001). The displaced fractures operated with hemiarthroplasty had a lower risk of reoperation compared to the undisplaced fractures (RR 0.32, 95%CI: 0.27–0.38; p<0.001). Patients treated with IF for undisplaced fractures were more satisfied, had less pain, and higher quality of life compared to patients treated with IF after displaced fractures (p<0.05). The patients treated with bipolar hemiarthroplasty for displaced fractures had, however, the least pain, were most satisfied, and reported the highest quality of life. Discussion and Conclusion. The clinical outcome after undisplaced femoral neck fractures treated with screw fixation was better than the results of screw fixation for displaced fractures, but poorer than the clinical results for patients with displaced femoral neck fractures operated with a bipolar hemiarthroplasty. However, the differences in clinical outcome were smaller than what is considered to be of clinical importance. One year postoperatively screw osteosynthesis of undisplaced femoral neck fractures in elderly patients still seems to be a good alternative

Mechanical ankle instability is elicited through examination and imaging. A subset of patients however report “functional” instability ie/ instability without objective radiological evidence. Little research compares operative outcomes between these groups. We hypothesised patients with “mechanical instability” were more likely to benefit from operative intervention than those with “functional instability”.

This was a single centre, retrospective case note review of prospectively collected data. Inclusion criteria: over six months of symptoms, failed conservative management, surgical stabilisation between 2016–2018. Data collected: demographics, operative procedure, preoperative and postoperative PROMs.

Nineteen patients were included. All had preoperative MRIs determining ligamentous involvement. Nine had radiological evidence of instability, eight had negative radiographs. Two were excluded due to no intraoperative radiographs.

There was no statistical difference in preoperative MOxFQ scores between the groups (p=0.2039). Preoperative EQ5D-TTO scores were statistically different (mean mechanical 0.58 vs functional 0.26, p=0.0162) but not EQ5D-VAS scores (mean mechanical 77 vs functional 53, p=0.0806).

Mechanical group's preoperative, 26 and 52 week scores respectively: Mean MOxFQ= 57.88, 22.13, 18.5. Mean EQ5D-TTO= 0.58, 0.78, 0.84. EQ5D-VAS= 77, 82, 82.5.

Functional group's preoperative, 26 and 52 week scores respectively: Mean MOxFQ= 71.87, 37.75, 23. Mean EQ5D-TTO 0.26, 0.63, 0.76. EQ5D-VAS 53, 80, 88.

This trend of improvement in PROMs was not reflected in patient satisfaction scores. 75% of respondents in the functional group reported dissatisfaction at 26 weeks versus no dissatisfaction in the mechanical group. We should consider counselling patients accordingly when offering surgery.

The concept of stainless steel dual mobility cups in total hip arthroplasty has demonstrated very low long-term instability rates and a 98% survival rate after 12 years. We systematically implanted titanium alloy acetabular cups during a one year period. The purpose of our retrospective study was to report the 18-year clinical outcome data in a homogeneous and continuous series of 103 primary total hip replacements after implantation of a cementless titanium cup. All patients were implanted with NOVAE Ti (SERF) cups made of titanium alloy combined with a retentive polyethylene liner and a 22.2 mm cobalt chrome prosthetic head. Mean patient age at the time of surgery was 53 years. All patients were clinically and radiographically evaluated. The overall 18-year actuarial cup survival rate with a 95% confidence interval was 87.4%. At last follow-up, there was no evidence of implant instability whereas acetabular aseptic loosening was reported in one case and high wear of the retentive liner in 9. The results of this investigation confirmed the long-term stability of dual-mobility implants. The main limitation of this system was early wear of the polyethylene liner in contact with the titanium metal back and reaction with third body along with loss of liner retentivity. In our study, titanium demonstrated favourable osteointegration properties but poor tribologic characteristics, therefore suggesting its interest at the bone-cup interface only

Arthritis of the mid-foot is a common presentation to the foot and ankle clinic, resulting from primary (idiopathic), post-traumatic, or inflammatory joint degeneration. Treatment in the initial stages is conservative, with midfoot fusion regarded as the operative treatment of choice; however there is a paucity of comparative and patient reported data regarding outcomes.

Patient reported outcome measures (PROMS), were prospectively collected from October-2015 to March-2018. Diagnoses were confirmed with image guided injection and initial management was conservative. In total, 66 patients were managed conservatively and 40 treated with mid-foot fusion. MOxFQ (Manchester Oxford Foot Questionnaire) and EQ-5D-3L (Euroqual) PROMS were collected pre-operatively, at 26 weeks and at 52 weeks.

In the operatively managed group, the female:male ratio was 5.7:1, with a mean age of 61 (range 24–80), while in the conservatively managed group, the ratio was 2.1:1 with mean age 63 (range 29–86).

In the surgically managed group, 88.2% of patients reported improvement in symptoms at 26 weeks and 88.9% at 52 weeks. This was greater than the conservatively managed group, in which 40.6% reported improvement at 26 weeks and 33.3% at 52 weeks. Mean MOxFQ improvement in the surgically managed group was +30.7 and +33.9 at 26 and 52 weeks respectively, and in the conservative group, +9.4 and +4.3, at 26 and 52 weeks. Similarly, favourable surgical outcomes were reported across all domains of EQ-5D-3L.

This study has highlighted excellent early outcomes after surgical treatment and may represent promise for those patients for whom conservative management fails.

We report the functional and socioeconomic long-term outcome of patients with pelvic ring injuries.

We identified 109 patients treated at a Level I trauma centre between 1973 and 1990 with multiple blunt orthopaedic injuries including an injury to the pelvic ring, with an Injury Severity Score (ISS) of ≥ 16. These patients were invited for clinical review at a minimum of ten years after the initial injury, at which point functional results, general health scores and socioeconomic factors were assessed.

In all 33 isolated anterior (group A), 33 isolated posterior (group P) and 43 combined anterior/posterior pelvic ring injuries (group A/P) were included. The mean age of the patients at injury was 28.8 years (5 to 55) and the mean ISS was 22.7 (16 to 44).

At review the mean Short-Form 12 physical component score for the A/P group was 38.71 (22.12 to 56.56) and the mean Hannover Score for Polytrauma Outcome subjective score was 67.27 (12.48 to 147.42), being significantly worse compared with the other two groups (p = 0.004 and p = 0.024, respectively). A total of 42 patients (39%) had a limp and 12 (11%) required crutches. Car or public transport usage was restricted in 16 patients (15%). Overall patients in groups P and A/P had a worse outcome. The long-term outcome of patients with posterior or combined anterior/posterior pelvic ring injuries is poorer than of those with an isolated anterior injury.

This study aimed to evaluate the effect of clavicular shortening, measured by three-dimensional computerized tomography (3DCT), on functional outcomes and satisfaction in patients with healed, displaced, midshaft clavicle fractures up to one year following injury.

The data used in this study were collected as part of a multicenter, prospective randomized control trial comparing open reduction and plate fixation with nonoperative treatment for displaced midshaft clavicle factures. Patients who were randomized to nonoperative treatment and who had healed by one year were included. Clavicle shortening relative to the uninjured contralateral clavicle was measured on 3DCT. Outcome analysis was conducted at six weeks, three months, six months and one year following injury and included the Disabilities of the Arm, Shoulder and Hand (DASH), Constant and Short Form-12 (SF-12) scores, and patient satisfaction.

48 patients were included. The mean shortening of injured clavicles, relative to the contralateral side, was 11mm (+/− 7.6mm) with a mean proportional shortening of 8percnt;. Proportional shortening did not significantly correlate with the DASH (p>0.42), Constant (p>0.32) or SF-12 (p>0.08) scores at any time point. There was no significant difference in the mean DASH or Constant scores at any followup time point both when the cut off for shortening was defined as one centimeter (p>0.11) or two centimeters (p>0.35). There was no significant difference in clavicle shortening between satisfied and unsatisfied patients (p>0.49).

This study demonstrated no association between shortening and functional outcome or satisfaction in patients with healed, displaced, midshaft clavicle fractures up to one year following injury.

Introduction. Reverse shoulder replacement is a surgical option for cuff tear arthropathy. However scapular notching is a concern. Newer designs of glenospheres are available to reduce scapular notching. Eccentric glenosphere with a lowered centre of rotation have been shown to improve range of adduction in vitro. We hypothesize that the eccentric glenosphere improve clinical outcomes and reduce scapular notching. Method. This is an ongoing randomized controlled double blind prospective clinical trial. Patients 70 years or older at North Shore hospital who have a diagnosis of cuff tear arthropathy and require surgery were consented for this study. Patients were allocated a concentric or eccentric 36 mm glenosphere intraoperatively, using a computer generated randomization contained in a sealed envelope. The surgical technique and post operative rehabilitation were standardized. Patients were followed up by a research nurse and postoperative radiographs were also taken at regular intervals. Clinical assessment include a visual analogue pain score, subjective shoulder rating, American Shoulder and Elbow Society Score, and Oxford shoulder score. Complications were checked for and radiographs were assessed for scapular notching. Results. There were 23 patients in the concentric and 24 patients in the eccentric glenosphere group. Average age and duration of follow up were comparable. There was no statistical significant difference but there was a trend towards better functional outcome and better range of motion in the eccentric glenosphere group. There was no scapular notching in the eccentric and three cases of scapular notching in the concentric glenosphere group. Conclusions. Reverse shoulder replacement significantly improve pain, function and range of motion in patients with cuff tear arthropathy. Eccentric glenosphere prevents scapular notching in the SMR reverse prosthesis

Background:

In 1931, Gaenslen reported treatment of haematogenous calcaneal osteomyelitis through an incision on the sole of the heel, without the use of antibiotics. We have modified his approach to allow shorter healing times and early mobilisation in a modern series of cases.

Between 1998 and 2002, 37 neuropathies in 32 patients with a displaced supracondylar fracture of the humerus who were referred to a nerve injury unit were identified. There were 19 boys and 13 girls with a mean age of 7.9 years (3.6 to 11.3). A retrospective review of these injuries was performed. The ulnar nerve was injured in 19, the median nerve in ten and the radial nerve in eight cases. Fourteen neuropathies were noted at the initial presentation and 23 were diagnosed after treatment of the fracture. After referral, exploration of the nerve was planned for 13 patients. Surgery was later cancelled in three because of clinical recovery. Six patients underwent neurolysis alone. Excision of neuroma and nerve grafting were performed in four. At follow-up, 26 patients had an excellent, five a good and one a fair outcome.

We have devised a new scoring system using visual analogue scales (VAS) to determine the functional outcome in 15 patients with 20 displaced intra-articular calcaneal fractures, confirmed by CT. The average follow-up was 19 months.

A VAS was completed separately by the patient, the surgeon and an independent assessor. It showed satisfactory agreement between observers and strong correlations with a General Health Survey (SF36), a pain scale (McGill Pain Questionnaire) and a disease-specific, historical scale for calcaneal fractures (the Rowe score).

Purpose

The purpose of this study were to investigate whether there is an association between the preoperative body mass index in total knee replacement patients and the effect three to five years postoperative.

Introduction

Displaced femoral neck fractures in elderly are normally treated with 2 screws/pins (IF) or bipolar hemiarthroplasty (HA). The aim of this study was to compare IF and HA as treatment for displaced femoral neck fractures using reoperations and functional result (patient satisfaction, pain, and quality of life) as outcome.
