Aims. The free latissimus dorsi muscle (LDM) flap represents a workhorse procedure in the field of trauma and plastic surgery. However, only a small number of studies have examined this large group of patients with regard to the morbidity of flap harvest. The aim of this prospective study was therefore to objectively investigate the morbidity of a free LDM flap. Methods. A control group (n = 100) without surgery was recruited to assess the differences in strength and range of motion (ROM) in the shoulder joint with regard to handedness of patients. Additionally, in 40 patients with free LDM flap surgery, these parameters were assessed in an identical manner. Results. We measured higher values for all parameters assessing force in the shoulder joint on the dominant side of patients in the control group. Moreover, LDM flap harvest caused a significant reduction in strength in the glenohumeral joint in all functions of the LDM that were assessed, ranging from 9.0% to 13.8%. Equally, we found a significantly reduced ROM in the shoulder at the side of the flap harvest. For both parameters, this effect was diminished, when the flap harvest took place on the dominant side of the patient. Conclusion. LDM flap surgery leads to a significant impairment of the strength and ROM in the shoulder joint. Moreover, the donor morbidity must be differentiated with regard to handedness: harvest on the non-dominant side potentiates the already existing difference in strength and ROM. Conversely, if the harvest takes place on the dominant side of the patient, this difference is diminished. Cite this article: Bone Jt Open 2024;5(12):1114–1119

Abstract. Background. Elderly patients with degenerative lumbar disease are increasingly undergoing posterior lumbar decompression without instrumented stabilisation. There is a paucity of studies examining clinical outcomes, morbidity & mortality associated with this procedure in this population. Methods. A retrospective analysis of aged 80–100 years who underwent posterior lumbar decompression without instrumented stabilisation at University Hospitals of Derby &Burton between 2016–2020. Results. Total 167 eligible patients, 163 octogenarians & 4 nonagenarians. Mean age was 82.78 ± 3.07 years. Mean length of hospital stay 4.79 ± 10.92 days. 76% were pain free at 3months following decompression. The average Charleston co-morbidity index (CCI) was 4.87. No association found with CCI in predicting mortality (ODD ratio 0.916, CI95%). 17patients suffered complications; dural tear (0.017%), post-op paralysis (0.017%), SSI(0.01%), and 0.001% of hospital acquired pneumonia, delirium, TIA, urinary retention, ileus, anaemia. High BMI (35+) was associated with increased incidence of complication (CI 95%, p<0.002). There was significant social drift following discharge as 147 patients went home and 4 patients to rehabilitation facility (p<0.001FE test). The mean operative time was 91.408±41.17 mins and mean anaesthetic time was 36.8±16.06 mins. Prolonged operative time was not associated with increased mortality.2year revision decompression rate was 0.011%. Conclusion. Posterior lumbar decompression without instrumented stablisation in elderly is safe & associated with low mortality with 99.5%survival at 1 year. It significantly improves PROMs & has extremely low revision rate. Incidence of post-op complication is <0.05% and 54% of patients get discharged within 72hours of surgery. Careful selection & optimising patients with high BMI would reduced perioperative morbidity and mortality

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.

Aims. The aim of this study was to assess orthopaedic oncologic patient morbidity resulting from COVID-19 related institutional delays and surgical shutdowns during the first wave of the pandemic in New York, USA. Methods. A single-centre retrospective observational study was conducted of all orthopaedic oncologic patients undergoing surgical evaluation from March to June 2020. Patients were prioritized as level 0-IV, 0 being elective and IV being emergent. Only priority levels 0 to III were included. Delay duration was measured in days and resulting morbidities were categorized into seven groups: prolonged pain/disability; unplanned preoperative radiation and/or chemotherapy; local tumour progression; increased systemic disease; missed opportunity for surgery due to progression of disease/lost to follow up; delay in diagnosis; and no morbidity. Results. Overall, 25 patients met inclusion criteria. There were eight benign tumours, seven metastatic, seven primary sarcomas, one multiple myeloma, and two patients without a biopsy proven diagnosis. There was no priority level 0, two priority level I, six priority level II, and 17 priority level III cases. The mean duration of delay for priority level I was 114 days (84 to 143), priority level II was 88 days (63 to 133), and priority level III was 77 days (35 to 269). Prolonged pain/disability and delay in diagnosis, affecting 52% and 40%,respectively, represented the two most frequent morbidities. Local tumour progression and increased systemic disease affected 32% and 24% respectively. No patients tested positive for COVID-19. Conclusion. COVID-19 related delays in surgical management led to major morbidity in this studied orthopaedic oncologic patient population. By understanding these morbidities through clearer hindsight, a thoughtful approach can be developed to balance the risk of COVID-19 exposure versus delay in treatment, ensuring optimal care for orthopedic oncologic patients as the pandemic continues with intermittent calls for halting surgery.

Aims. Elective orthopaedic surgery was cancelled early in the COVID-19 pandemic and is currently running at significantly reduced capacity in most institutions. This has resulted in a significant backlog to treatment, with some hospitals projecting that waiting times for arthroplasty is three times the pre-COVID-19 duration. There is concern that the patient group requiring arthroplasty are often older and have more medical comorbidities—the same group of patients advised they are at higher risk of mortality from catching COVID-19. The aim of this study is to investigate the morbidity and mortality in elective patients operated on during the COVID-19 pandemic and compare this to a pre-pandemic cohort. Primary outcome was 30-day mortality. Secondary outcomes were perioperative complications, including nosocomial COVID-19 infection. These operations were performed in a district general hospital, with COVID-19 acute admissions in the same building. Methods. Our institution reinstated elective operations using a “Blue stream” pathway, which involves isolation before and after surgery, COVID-19 testing pre-admission, and separation of ward and theatre pathways for “blue” patients. A register of all arthroplasties was taken, and their clinical course and investigations recorded. Results. During a seven-month period, 340 elective arthroplasties were performed. There was zero mortality. One patient had a positive swab for COVID-19 while an inpatient, but remained asymptomatic. There were two readmissions within a 12-week period for hip dislocation. Patients had a mean age of 68 years (28 to 90), mean BMI of 30 kg/m. 2. (19.0 to 45.6), and mean American Society of Anesthesiologists grade of 2 (1 to 3). Conclusion. Results show no increased morbidity or mortality in this cohort of patients compared to the same hospital’s morbidity and mortality pre-COVID-19. The screened pathway for elective patients is effective in ensuring that patients can be safely operated on electively in an acute hospital. This study should reassure clinicians and patients that arthroplasties can be carried out safely when the appropriate precautions are in place. Cite this article: Bone Jt Open 2021;2(11):940–944

Aims. This study aimed to evaluate the clinical application of the PJI-TNM classification for periprosthetic joint infection (PJI) by determining intraobserver and interobserver reliability. To facilitate its use in clinical practice, an educational app was subsequently developed and evaluated. Methods. A total of ten orthopaedic surgeons classified 20 cases of PJI based on the PJI-TNM classification. Subsequently, the classification was re-evaluated using the PJI-TNM app. Classification accuracy was calculated separately for each subcategory (reinfection, tissue and implant condition, non-human cells, and morbidity of the patient). Fleiss’ kappa and Cohen’s kappa were calculated for interobserver and intraobserver reliability, respectively. Results. Overall, interobserver and intraobserver agreements were substantial across the 20 classified cases. Analyses for the variable ‘reinfection’ revealed an almost perfect interobserver and intraobserver agreement with a classification accuracy of 94.8%. The category 'tissue and implant conditions' showed moderate interobserver and substantial intraobserver reliability, while the classification accuracy was 70.8%. For 'non-human cells,' accuracy was 81.0% and interobserver agreement was moderate with an almost perfect intraobserver reliability. The classification accuracy of the variable 'morbidity of the patient' reached 73.5% with a moderate interobserver agreement, whereas the intraobserver agreement was substantial. The application of the app yielded comparable results across all subgroups. Conclusion. The PJI-TNM classification system captures the heterogeneity of PJI and can be applied with substantial inter- and intraobserver reliability. The PJI-TNM educational app aims to facilitate application in clinical practice. A major limitation was the correct assessment of the implant situation. To eliminate this, a re-evaluation according to intraoperative findings is strongly recommended. Cite this article: Bone Joint Res 2024;13(1):19–27

Aims. Using the Australian and New Zealand Hip Fracture Registry (ANZHFR) data, this study aimed to identify patient, fracture, and management factors associated with survival, mobility and residential status at 120 days. This will allow future interventions to target modifiable risk factors to improve the overall care of patients with hip fractures. Methods. All NZ patients from 2018 – 2020 were included. Baseline demographics, management factors, and outcomes were recorded. Key outcomes were change in walking status, residential status and survival at 120 days. Univariate analysis was performed to compare differences in demographics, surgical and management factors for the key variables. Multivariate analysis was conducted to identify factors independently associated with outcomes. Results. Data from 9432 patients were analysed. The average age was 82.8 years (SD 9.8). 70.3% were females. 39.5% of patients were cognitively impaired on admission, 71.4% were from their own residence. At 120 days post injury, 10.9% (1029) had died 1029 (10.9%), 15.3% (1034) had a decrease in their residential status, 44.9% (2966) had a reduction in walking ability. On multivariate analysis; older age (RR1.1/yr, p<0.001), male sex (RR1.7, P<0.001), cognitive impairment (RR2.2, p<0.001) and ASA>3 (RR3.7, p=0.015) were risk factors for death. Similarly, increasing age (RR1.1 per year, p<0.001), cognitive impairment (RR1.2, p=0.04) and ASA>3 (RR2.9, p=0.047) were significant risk factors for worsening residential status. Decreasing mobility was associated with extracapsular fractures (RR1.4, p=0.01). After adjustment for demographics, ASA and fracture type, performing total hip arthroplasty was preventative for both worsening residential status (RR0.23, p<0.001) and decreasing walking ability (RR 0.21, p<0.001). There was no significant survival, functional or revision differences for other fixation types. Conclusion. There is a significant decline in walking ability post hip fracture which may be a key contributor to long-term morbidity. The benefits of THA in preserving mobility and independence should be further investigated. Additional discharge planning and multi-disciplinary team input are likely required for high-risk patients of older age, with cognitive impairment and extracapsular fractures

Aims. Within the UK, around 70,000 patients suffer neck of femur (NOF) fractures annually. Patients presenting with this injury are often frail, leading to increased morbidity and a 30-day mortality rate of 6.1%. COVID-19 infection has a broad spectrum of clinical presentations with the elderly, and those with pre-existing comorbidities are at a higher risk of severe respiratory compromise and death. Further increased risk has been observed in the postoperative period. The aim of this study was to assess the impact of COVID-19 infection on the complication and mortality rates of NOF fracture patients. Methods. All NOF fracture patients presenting between March 2020 and May 2020 were included. Patients were divided into two subgroup: those with or without clinical and/or laboratory diagnosis of COVID-19. Data were collected on patient demographics, pattern of injury, complications, length of stay, and mortality. Results. Overall, 132 patients were included. Of these, 34.8% (n = 46) were diagnosed with COVID-19. Bacterial pneumonia was observed at a significantly higher rate in those patients with COVID-19 (56.5% vs 15.1%; p =< 0.000). Non respiratory complications such as acute kidney injury (30.4% vs 9.3%; p =0.002) and urinary tract infection (10.9% vs 3.5%; p =0.126) were also more common in those patients with COVID-19. Length of stay was increased by a median of 21.5 days in patients diagnosed with COVID-19 (p < 0.000). 30-day mortality was significantly higher in patients with COVID-19 (37.0%) when compared to those without (10.5%; p <0.000). Conclusion. This study has shown that patients with a neck of femur fracture have a high rate of mortality and complications such as bacterial pneumonia and acute kidney injury when diagnosed with COVID-19 within the perioperative period. We have demonstrated the high risk of in hospital transmission of COVID-19 and the association between the infection and an increased length of stay for the patients affected.

Abstract. Introduction. Minimising postoperative complications and mortality in COVID-19 patients who were undergoing trauma and orthopaedic surgeries is an international priority. Aim was to develop a predictive nomogram for 30-day morbidity/mortality of COVID-19 infection in patients who underwent orthopaedic and trauma surgery during the coronavirus pandemic in the UK in 2020 compared to a similar period in 2019. Secondary objective was to compare between patients with positive PCR test and those with negative test. Methods. Retrospective multi-center study including 50 hospitals. Patients with suspicion of SARS-CoV-2 infection who had underwent orthopaedic or trauma surgery for any indication during the 2020 pandemic were enrolled in the study (2525 patients). We analysed cases performed on orthopaedic and trauma operative lists in 2019 for comparison (4417). Multivariable Logistic Regression analysis was performed to assess the possible predictors of a fatal outcome. A nomogram was developed with the possible predictors and total point were calculated. Results. Of the 2525 patients admitted for suspicion of COVID-19, 658 patients had negative preoperative test, 151 with positive test and 1716 with unknown preoperative COVID-19 status. Preoperative COVID-19 status, sex, ASA grade, urgency and indication of surgery, use of torniquet, grade of operating surgeon and some comorbidities were independent risk factors associated with 30-day complications/mortality. The 2020 nomogram model exhibited moderate prediction ability. In contrast, the prediction ability of total points of 2019 nomogram model was excellent. Conclusions. Nomograms can be used by orthopaedic and trauma surgeons as a practical and effective tool in postoperative complications and mortality risk estimation

Introduction This study was conducted to quantify the incidence of gastrointestinal morbidity and identify risk factors for developing gastrointestinal morbidity following spinal surgery in children. Method A retrospective review was conducted on 253 surgical spinal procedures performed over a 5 year period at Starship Children’s Hospital. Multivariate logistic regression analysis was used to identify significant risk factors. Co-morbidity included co-existing cardiac, respiratory, genitorurinary or central nervous system problems, or delayed development. Results Seventy eight (77.9%) percent of the study population developed gastrointestinal morbidity and this significantly prolonged the median post-operative hospital stay (8 days vs.4 days; p< 0.0001). Emesis (50.6%), paralytic ileus (42.3%) and constipation (22.5%) were the most frequent gastrointestinal morbidities. Significant risk factors for developing gastrointestinal morbidity were fusion surgery (p< 0.01), co-morbidities (p-value) and duration of post-operative opioid use (p-value). Discussion There is a high incidence of gastrointestinal morbidity after paediatric spinal surgery. The consequent prolonged hospital stay has clinical implications to both the patient and the institution. We have further identified risk factors for developing gastrointestinal morbidity, of which the duration of post-operative opioid use is modifiable. Awareness of those with the other significant risk factors identified by this study could assist in the timely implementation of appropriate treatment

Aims: Bone graft substitutes have been advocated recently to avoid the potential morbidity associated with harvest of autogenous iliac crest graft. However, no commercially available graft equals autogenous bone osteo-inductive and osteoconductive qualities. We reviewed our patientsñ morbidity after harvest of 240 anterior iliac crest bone grafts for procedures involving the foot and ankle. Methods: A computerized analysis of patient records was undertaken to identify all patients under-all going a unique unicortical iliac crest bone graft harvest over a 10-year period from the senior authorñs practice. All patients were contacted either by phone or mailed questionnaire inquiring about the postoperative morbidity of the procedure. Charts were reviewed for any related complications. Results: 200 patients were available for follow-up (range 1 to 10 years). Of these patients 98% were satisþed or very satisþed with their bone graft harvest. 10 patients complained of minor residual numbness lateral to the harvest site. None complained of problems with ambulation related to graft site pain. 7% reported that their graft site pain was greater than their operative site pain during the postoperative period. 95% of patientsñ pain resolved within 4 weeks of the operative procedure. No patients incurred extra hospital days as a result of the bone graft harvest. No deep infections occurred, although there was a 6% incidence of postoperative hematoma/seroma. Conclusions: Despite common sentiment, harvesting of autogenous iliac crest bone graft yields minimal morbidity, no extra hospitalization, and optimal bone graft material at similar or lesser cost than bone graft substitutes while being overwhelmingly acceptable to patients. Bone graft substitutes may not be as cost-effective as currently thought

Aims. The COVID-19 pandemic posed significant challenges to healthcare systems across the globe in 2020. There were concerns surrounding early reports of increased mortality among patients undergoing emergency or non-urgent surgery. We report the morbidity and mortality in patients who underwent arthroplasty procedures during the UK first stage of the pandemic. Methods. Institutional review board approval was obtained for a review of prospectively collected data on consecutive patients who underwent arthroplasty procedures between March and May 2020 at a specialist orthopaedic centre in the UK. Data included diagnoses, comorbidities, BMI, American Society of Anesthesiologists grade, length of stay, and complications. The primary outcome was 30-day mortality and secondary outcomes were prevalence of SARS-CoV-2 infection, medical and surgical complications, and readmission within 30 days of discharge. The data collated were compared with series from the preceding three months. Results. There were 167 elective procedures performed in the first three weeks of the study period, prior to the first national lockdown, and 57 emergency procedures thereafter. Three patients (1.3%) were readmitted within 30 days of discharge. There was one death (0.45%) due to SARS-CoV-2 infection after an emergency procedure. None of the patients developed complications of SARS-CoV-2 infection after elective arthroplasty. There was no observed spike in complications during in-hospital stay or in the early postoperative period. There was no statistically significant difference in survival between pre-COVID-19 and peri-COVID-19 groups (p = 0.624). We observed a higher number of emergency procedures performed during the pandemic within our institute. Conclusion. An international cohort has reported 30-day mortality as 28.8% following orthopaedic procedures during the pandemic. There are currently no reports on clinical outcomes of patients treated with lower limb reconstructive surgery during the same period. While an effective vaccine is developed and widely accepted, it is very likely that SARS-CoV2 infection remains endemic. We believe that this report will help guide future restoration planning here in the UK and abroad. Cite this article: Bone Jt Open 2021;2(5):323–329

Introduction. The aim of this study is to report the 30 day COVID-19 related morbidity and mortality of patients assessed as SARS-CoV-2 negative who underwent emergency or urgent orthopaedic surgery in the NHS during the peak of the COVID-19 pandemic. Method. A retrospective, single centre, observational cohort study of all patients undergoing surgery between 17 March 2020 and 3May 2020 was performed. Outcomes were stratified by British Orthopaedic Association COVID-19 Patient Risk Assessment Tool. Patients who were SARS-CoV-2 positive at the time of surgery were excluded. Results. Overall, 96 patients assessed as negative for SARS-CoV-2 at the time of surgery underwent 100 emergency or urgent orthopaedic procedures during the study period. Within 30 days of surgery 9.4% of patients (n = 9) were found to be SARS-CoV-2 positive by nasopharyngeal swab. The overall 30 day mortality rate across the whole cohort of patients during this period was 3% (n = 3). Of those testing positive for SARS-CoV-2 66% (n = 6) developed significant COVID-19 related complications and there was a 33% 30-day mortality rate (n = 3). Overall, the 30-day mortality in patients classified as BOA low or medium risk (n = 69) was 0%, whereas in those classified as high or very high risk (n = 27) it was 11.1%. Conclusion. Orthopaedic surgery in SARS-CoV-2 negative patients who transition to positive within 30 days of surgery carries a significant risk of morbidity and mortality. In lower risk groups, the overall risk of becoming SARS-CoV-2 positive, and subsequently developing a significant postoperative related complication, was low even during the peak of the pandemic. In addition to ensuring patients are SARS-CoV-2 negative at the time of surgery it is important that the risk of acquiring SARS-CoV-2 is minimized through their recovery.

Malnutrition is considered a risk factor for postoperative complications in total hip and knee arthroplasty, though prospective studies investigating this assumption are lacking. The aim of this study was to prospectively analyse the 90-day postoperative complications, postoperative length of stay (LOS) and readmission rates of patients undergoing primary total hip and total kneearthroplasty using albumin, total lymphocyte count (TLC) and transferrin as serum markers of potential malnutrition.

603 primary hip and 823 primary knee arthroplasties over a 3-year period from a single centre wereprospectively analysed. BMI, demographic and comorbidity data were recorded. Complications werecategorised as surgical site infection, venous thromboembolism (deep vein thrombosis andpulmonary embolus), implant related (such as dislocation), and non-implant related (such aspneumonia). Outcomes were compared between groups, with malnutrition defined as serumalbumin <3.5g/dL, transferrin <200 mg/dL, or TLC <1,500 cells/mm³.

Potential malnutrition was present in 9.3% of the study population. This group experienced a longeraverage LOS at 6.5 days compared to the normal albumin group at 5.0 days (p=0.003). Surgical siteinfection rate was higher in the malnourished group (12.5 vs 7.8%, p=0.02). There was no differencebetween the two groups in implant related complications (0.8 vs 1.0%, p=0.95) medicalcomplications (7.8 vs 13.3%, p=0.17), rate of venous thromboembolism (2.3 vs 2.7%) or 90-dayreadmission rate (14.1 vs 17.0%, p=0.56). TLC and transferrin were not predictive of any of theprimary outcomes measured (p<0.05). Pacific Island (p<0.001), Indian (p=0.02) and Asian (p=0.02) patients had lower albumin than NZ European.

This study demonstrates an association between low albumin levels and increased postoperativeLOS and surgical site infection in total joint arthroplasty, providing rationale for consideration ofpreoperative nutritional screening and optimisation.

Introduction. Total hip arthroplasty is one of the most successful operations performed by an orthopaedic surgeon. There are three surgical approaches in use since Charnley popularised the trans-trochanteric approach. Opinion has been divided as to which approach is superior. Aim. This study was designed to examine the difference in morbidity between the classical Charnley trans-tro-chanteric approach and the antero-lateral trans-gluteal (Hardinge) approach in primary hip arthroplasty. Methods. Information on 891 patients, who underwent primary total hip arthroplasty performed by a single surgeon, was collected prospectively between 1998–2003 using a modified SF-36 form, pre-operatively, intra-operatively, and at three months. Information collected includes patient demographics, diagnosis, intra-operative blood-loss, and post-operative satisfaction and range of motion. Information was collected on the Excel database and analysed using Minitab statistical package. Results. The two groups were statistically similar for gender and side of pathology. There was no statistical difference in blood-loss between the groups. There was higher morbidity in the TT group. More patients were doubtful or dissatisfied with the THR in the TT group. There was a greater range of motion in the Hardinge group. Conclusion. In this study population, the trans-trochanteric approach was associated with higher morbidity, a lower patient satisfaction rating and a lower range of motion

The rate of litigation following personal injury is rising at an exponential rate with no concomitant rise in the actual incidence of these injuries. It is recognised that physical injury can lead to mental health disturbance and such mental health disturbance can delay recovery following injury. No previous study has assessed the incidence of pre-existing mental health morbidity amongst personal injury claimants. The general practitioners records of 750 consecutive personal injury claimants were examined. Mental health diagnoses prior to the index injury were noted and classified using the Diagnostic and Statistical Manual of the American Association of psychiatry. Any treatment by mental health professionals was noted. A highly significant excess of pre-injury psychiatric morbidity was identified in the study population. There was a 40% incidence of at least one mental health diagnosis. There was a highly significant excess of depression and anxiety. 10% of the study group had received treatment from at least one mental health professional. Pre-existing psychiatric morbidity appears to be an independent predictive factor for pursuing litigation following personal injury. In light of existing knowledge that such psychiatric morbidity often results in prolongation of physical symptoms and poor response to standard treatment regimes, it is important to recognise such patients when providing a prognosis in a medico-legal context

The Ganz trochanteric flip osteotomy has gained popularity in recent years as a surgical approach that can be used when performing debridement surgery and hip resurfacing. The advantages include preservation of blood supply to the femoral head, maintenance of abductor strength and exposure. Morbidity associated with the trochanteric osteotomy is however a problem. We reviewed the complications associated with the trochanteric flip in 367 patients that had undergone hip resurfacing arthroplasty. Pain, either felt deep within the groin or from prominent screws heads laterally was a significant problem for 96 patients (26.1%) and necessitated screw removal under general anaesthesia at a mean time of 16 months postop. Of these, 14 patients (14.5%) continued to have pain, with 8 patients proceeding to revision surgery; 5 for refractory pain, 1 for aseptic loosening, 1 for aseptic lymphocyte dominated vasculitis associated lesion (ALVAL) and 1 for acetabular soft tissue impingement. Trochanteric non-union, leading to further surgery, was diagnosed in 24 patients (6.5%) whom underwent reattachment at a mean time of 6 months postop. Within this group the majority of patients were male (16), with a mean age of 53.5 years (range 35 to 65). Trochanteric non-union was associated with smoking, diabetes, obesity, age and non-compliance. Following reattachment surgery, all patients went on to union. In total 120 patients experienced complications associated with the trochanteric osteotomy that resulted in a need for further surgery, a re-operation rate of 32.6%. Pain from trochanteric screws appears to be the over whelming issue. Surgeons using the trochanteric flip should be aware of the morbidity associated with the approach and counsel patients accordingly pre-operatively. Patients presenting with ongoing pain following screw removal should be investigated extensively for serious underlying problems

Statement of Purpose We describe the donor site morbidity of hyaline cartilage biopsy from the trochlea of the knee when used for ACI in the ankle joint. Methods We studied 12 patients who received a two stage ACI procedure on the talus, performed by three consultant surgeons. The first stage involved knee arthroscopy and harvest of cartilage for culture and stage two the transplantation of a chondrocyte culture to the ankle joint. During the first stage knee arthroscopy using a superolateral approach, the cartilage specimens were taken from a minor load bearing area of either the central or superolateral trochlea using a 5mm gouge. Clinical outcomes were assessed using a patient satisfaction score and the Lysholm knee score, taken both pre- and post- operatively at 3 months and annually thereafter. Results The mean age of the patient group was 42. The patient satisfaction questionnaires showed 11 patients to be ‘pleased’ or ‘extremely pleased’ with their ACI procedure which was sustained in the patients with up to four years follow up. The mean Lysholm score preoperatively was 98/100. Postoperatively eight patients had a reduced score (mean reduction 14) at twelve months follow up. In those patients with new knee symptoms at one year, analysis of the Lysholm score components showed the Locking and Limp categories to be the most frequent cause of a reduced score. Two patients had repeat knee arthroscopy at 18 months and 2 years postoperatively for symptoms of catching, anterior knee pain and swelling. Discussion The Lysholm knee score has components which may be affected by ipsilateral joint problems, which contribute to 20% of the overall score. However those patients with an abnormal Lysholm knee score postoperatively have gained an improved Mazur ankle score since their ACI. The procedure of cartilage harvest from the trochlea of the knee has an associated donor site morbidity which is present at one year. Ninety two percent of patients were pleased or extremely pleased with their ACI procedure, despite the requirement of surgery on their knee and it would seem that the amount of early knee morbidity these patients experience is outweighed by the improvement in symptoms in the treated joint. Ideally to optimise cartilage repair less morbid techniques to obtain cartilage need to be identified or alternatively mesenchymal stem cells could be used as an alternative source, which has already had limited success in the knee and might also be applied to other joints

This study aims to assess prospectively whether measurement of perioperative Troponin T is a useful predictor of potential morbidity and mortality in patients undergoing surgery for fractured neck of femur. All patients aged 65 years and over presenting with a fractured neck of femur over a 4-month period were initially included. Exclusion criteria were renal failure, polymyositis and conservative fracture management. Troponin T levels were measured on admission, day 1 and 2 post-surgery. According to local protocol, a level of >0.03ng/mL was considered to be raised. Outcome measures adverse were cardiorespiratory events (myocardial infarction, congestive cardiac failure, unstable angina, major arrhythmias requiring treatment and pulmonary embolism), death and length of inpatient stay. 108 patients were recruited after application of the exclusion criteria. 42 (38.9%) showed a rise in Troponin T >0.03ng/mL in at least one sample. Of these, 25 (59.5%) sustained at least outcome complication, as opposed to 7 (10.6%) from the group with no Troponin T rise (p<0.001). The mean length of stay was 25.7 days for patients with elevated Troponin T levels, compared with 18.3 days in the normal group (p<0.012). There were 9 deaths in the raised Troponin group (21.4%), and 5 (7.6%) in the group with no rise (p<0.05). The principal causes of early death after hip fracture surgery are cardiac failure and myocardial infarction. Troponin T is a sensitive enzymatic marker of myocardial injury. The association between raised Troponin and hip fractures has not previously been made. In our series, 38.9% showed a perioperative Troponin rise. This was significantly associated with increased morbidity, mortality and longer hospitalisation. Many hip fracture patients appear to be having silent cardiorespiratory events, contributing significantly to perioperative morbidity. We recommend measurement of Troponin levels in all such patients to identify this risk and initiate appropriate treatment
