Aims

The Peri-Implant and PeriProsthetic Survival AnalysiS (PIPPAS) study aimed to investigate the risk factors for one-year mortality of femoral peri-implant fractures (FPIFs).

Aims

Understanding of open fracture management is skewed due to reliance on small-number lower limb, specialist unit reports and large, unfocused registry data collections. To address this, we carried out the Open Fracture Patient Evaluation Nationwide (OPEN) study, and report the demographic details and the initial steps of care for patients admitted with open fractures in the UK.

Aims

The Open-Fracture Patient Evaluation Nationwide (OPEN) study was performed to provide clarity in open fracture management previously skewed by small, specialist centre studies and large, unfocused registry investigations. We report the current management metrics of open fractures across the UK.

Aims

The aim of this study to compare 30-day survival and recovery of mobility between patients mobilized early (on the day of, or day after surgery for a hip fracture) and patients mobilized late (two days or more after surgery), and to determine whether the presence of dementia influences the association between the timing of mobilization, 30-day survival, and recovery.

Sacral tumours are rare and can present difficult diagnostic and therapeutic challenges even at an early diagnosis. Surgical resection margins have a reported prognostic role in local recurrence and improved survival. Successful management is achieved within a specialist multidisciplinary service and involves combination chemotherapy, radiotherapy and surgery. We present our experience of patients with sacral tumours referred to our unit, who underwent total and subtotal sacrectomy procedures. Materials and Methods. Between 1995 and 2010, we identified twenty-six patients who underwent a total or subtotal sacrectomy operation. Patients were referred from around the United Kingdom to our services. We reviewed all case notes, operative records, radiological investigations and histopathology, resection margins, post operative complications, functional outcomes and we recorded long-term survival outcomes. Patients who were discharged to local services for continued follow up or further oncological treatment were identified and information was obtained from their general practitioner or oncologist. We reviewed the literature available on total sacrectomy case series, functional outcomes and soft tissue reconstruction. Results. We reviewed 26 patients, 16 male and 10 female, with a mean age at presentation of 53.4 years (range 11–80 years). Duration of symptoms ranged from 2 weeks to 6 years; lower back pain and sciatica were amongst the most common presenting features. Histological diagnoses included chordoma, Ewing's, malignant peripheral nerve sheath tumour, chondromyxoid fibroma, spindle cell sarcoma, synovial sarcoma, chondrosarcoma. A combined approach was used in two-thirds of patients and most of these patients had a soft tissue reconstruction with pedicled vertical rectus myocutaneous flap. Complications were categorised into major and minor and subdivided into wound, bladder and bowel symptoms. Wound complications and need for further intervention were more common amongst the patient group who did not have simultaneous soft tissue reconstruction at operation. All patients had a degree of bladder dysfunction in the early postoperative period. We present survivorship curves including recurrence and development of metastases. Conclusion. Total sacrectomy procedures carry a high risk of associated morbidity but can improve survival amongst specific groups of patients. They present challenges in diagnosis and management, but must be referred to a specialist service, that will instigate appropriate investigations and treatment regimes within a multidisciplinary setting. The expansion of services from other specialties required for the postoperative and ongoing rehabilitation plays an important role in overall management and appropriate pathways to coordinate these services are necessary

Background. Extendable proximal femoral replacements(PFR) are used in children with bone tumours in proximity to the proximal femoral physis, previously treated by hip disarticulation. Long-axis growth is preserved, allowing limb salvage. Since 1986, survival outcomes after limb salvage and amputation have been known to be equal. Method. Retrospective review of all patients <16years undergoing extendable PFR at Royal National Orthopaedic Hospital (UK) between 04/1996 and 01/2006, recording complications, failures, procedures undertaken and patient outcomes. Results. 8 patients (mean age 8.9±3 years) underwent extendable PFR for Ewing's Sarcoma(5), Osteosarcoma(1), Chondrosarcoma(1) and rhabdomyosarcoma(1). 2 primary PFRs failed (infection of unknown source & local recurrence, both at 26months); 2 required revision for full extension (1 became infected at revision, requiring 2 stage revision). 3 patients had the original prosthesis in situ at last follow-up (mean 7.2;range 3–10.5years). 1 patient had no implant complications, but died (neutropaenic sepsis) 63 days after implant insertion. 2 were treated for recurrence but disease free at last review. 5 were continuously disease free. 5 patients were lengthened a mean 3.7cm; 2 were not lengthened.1 had incomplete data. 5 patients suffered subluxation/dislocation (mean 15.6months), 3 recurrently. Each underwent a mean 1.6 open & 1.4 closed procedures for the displaced joint. 3 patients had 4 open reductions and acetabuloplasties and 2 patients were converted to THR, with 3 major complications: 2 sciatic nerve palsies and 1 (THR) infection. The 5th patient was due for acetabuloplasty but had hip disarticulation for recurrence. Acetabular erosion occurred in 3; 2 were revised to THR (3.5 & 6.8years). 3 patients suffered peri-prosthetic supracondylar fracture (treated conservatively). 5 patients were revised to THR (mean 5.9years): 2 for dislocation, 2 for acetabular erosion & 1 for infection. 1 underwent amputation and another died. Only 1 surviving implant was not converted to THR: this patient had progressive acetabular erosion at 10.5 years & will eventually require THR. The amputee had poor hip function prior to disarticulation but went on to become an international Paralympic sportsman and had very good function 11.4 years post-disarticulation. 3 patients had fixed hip adduction deformity. 1 was isolated and treated with adductor tenotomy, whilst 2 were associated with knee flexion deformity (one required in-patient physiotherapy; the other prosthetic shortening). Conclusions. Extendable PFR permits limb salvage with psychological & functional benefits, but complications are common and some are specific to PFR. Surgery for these may result in further complications. Patients should be warned of the high conversion rate to THR. All the above should be borne in mind when selecting patients. As illustrated above, functional outcome is sometimes better with amputation

Introduction. Since the introduction of 3rd generation Metal-on-Metal-Hip-Resurfacing-Arthroplasty (MoMHRA), thousands of such prostheses have been implanted worldwide in younger patients with end-stage hip osteoarthritis. However, no independent centre has reported their medium-to-long term outcome. The aim of this study is to report the ten year survival and outcome of the Birmingham Hip Resurfacing (BHR), the most commonly used MoMHRA worldwide. Methods. Since 1999, 648 BHRs were implanted in 555 patients, the majority of which were male (326). The mean age at surgery was 52.1years (range: 17–82), with primary OA as most common indication (85%). Mean follow up was 7.1years (range: 1–11). The Oxford Hip Score (OHS) and UCLA questionnaires were sent to all patients. Implant survival was established, with revision as the end point. Sub-analysis was performed by gender, femoral component size (small: <45mm, standard: 46–52, large: >53mm) and age at surgery (young:<50yrs, old:>50yrs). Results. Preliminary results show that survival and clinical outcome were better in men than women (p=0.013) and in patients with large and standard components compared to small (p=0.005). In women the survival and clinical outcome were worse in the young than the old (p=0.049). In men there was no difference in survival or clinical outcome between the young and old (p=0.106). In young men the 10-year survival was 95%, the mean OHS was 45 and the mean UCLA score was 8.1. Conclusion. The results of resurfacing are good in men. They perform particularly well in the young and highly active men who tend to have problems with conventional hip replacements

Introduction. The main symptoms in multiple myeloma are the result of skeletal destruction mainly the vertebral column. The current treatments for multiple myeloma include radiotherapy and chemotherapy but unfortunately it is still incurable. However, the symptoms and quality of life of these patients can be improved by cement augmentation which has gained popularity in the recent years. Aim. To analyse the efficacy and safety of cement augmentation and to assess the survival and outcome of the patients with vertebral fractures secondary to multiple myeloma. Material and Methods. In this retrospective study, we reviewed the data over the last 3 years. Medical records review included correction of vertebral angle (VA), assessment of disability, survival and postoperative improvement in pain and functional status. Results. We reviewed 12 patients with 48 vertebral compression fractures including 9 male and 3 female patients. Mean age was 62.5 years (41–85). 5 patients had single vertebral involvement while 7 had multiple fractures at different levels in thoracolumbar spine. Average length of follow-up was 20.3 months (14–33 months). Based on Modified Tokuhashi score, the expected survival was less than 12 months in 2 patients and more than 12 months in the remaining patients. 11 patients are alive till date with average survival of 26 months (18–42 months) while 1 patient died, 23 months after the initial correction surgery. Prior to correction, the average vertebral angle (VA) was 10.60 (2.30 to 25.20) and after cement augmentation the average VA was 7.00 (1.60–22.80). Mean correction achieved was 3.60. There was no loss of vertebral height in any patient until their latest follow-up. Karnofsky performance score was more than 70 in 5 patients, 50–70 in 6 and less than 50 in 1 patient preoperatively while it improved to more than 70 in all patients postoperatively which indicates improvement in their functional status. All patients reported improvement in their pain level after surgery. No cement leakage or major complication occurred in these patients. Conclusion. Cement augmentation is a safe and effective way of treating the symptoms of multiple myeloma which occur due to vertebral metastases. It results in excellent pain control and improvement in quality of life

The spiral blade modification of the Dynamic Hip Screw (DHS) was designed for superior biomechanical fixation in the osteoporotic femoral head. Our objective was to compare clinical outcomes and in particular the incidence of loss of fixation.

In a series of 197 consecutive patients over the age of 50 years treated with DHS-blades (blades) and 242 patients treated with conventional DHS (screw) for AO/OTA 31.A1 or A2 intertrochanteric fractures were identified from a prospectively compiled database in a level 1 trauma centre. Using propensity score matching, two groups comprising 177 matched patients were compiled and radiological and clinical outcomes compared. In each group there were 66 males and 111 females. Mean age was 83.6 (54 to 100) for the conventional DHS group and 83.8 (52 to 101) for the blade group.

Loss of fixation occurred in two blades and 13 DHSs. None of the blades had observable migration while nine DHSs had gross migration within the femoral head before the fracture healed. There were two versus four implant cut-outs respectively and one side plate pull-out in the DHS group. There was no significant difference in mortality and eventual walking ability between the groups. Multiple logistic regression suggested that poor reduction (odds ratio (OR) 11.49, 95% confidence intervals (CI) 1.45 to 90.9, p = 0.021) and fixation by DHS (OR 15.85, 95%CI 2.50 to 100.3, p = 0.003) were independent predictors of loss of fixation.

The spiral blade design may decrease the risk of implant migration in the femoral head but does not reduce the incidence of cut-out and reoperation. Reduction of the fracture is of paramount importance since poor reduction was an independent predictor for loss of fixation regardless of the implant being used.

We undertook a prospective randomised controlled trial involving 400 patients with a displaced intracapsular fracture of the hip to determine whether there was any difference in outcome between treatment with a cemented Thompson hemiarthroplasty and an uncemented Austin-Moore prosthesis. The surviving patients were followed up for between two and five years by a nurse blinded to the type of prosthesis used.

The mean age of the patients was 83 years (61 to 104) and 308 (77%) were women. The degree of residual pain was less in those treated with a cemented prosthesis (p < 0.0001) three months after surgery. Regaining mobility was better in those treated with a cemented implant (p = 0.005) at six months after operation. No statistically significant difference was found between the two groups with regard to mortality, implant-related complications, re-operations or post-operative medical complications.

The use of a cemented Thompson hemiarthroplasty resulted in less pain and less deterioration in mobility than an uncemented Austin-Moore prosthesis with no increase in complications.

We report gender differences in the epidemiology and outcome after hip fracture from the Scottish Hip Fracture Audit, with data on admission and at 120 days follow-up from 22 orthopaedic units across the country between 1998 and 2005. Outcome measures included early mortality, length of hospital stay, 120-day residence and mobility. A multivariate logistic regression model compared outcomes between genders. The study comprised 25 649 patients of whom 5674 (22%) were men and 19 975 (78%) were women. The men were in poorer pre-operative health, despite being younger at presentation (mean 77 years (60 to 101) vs 81 years (50 to 106)). Pre-fracture residence and mobility were similar between genders.

Multivariate analysis indicated that the men were less likely to return to their home or mobilise independently at the 120-day follow-up. Mortality at 30 and 120 days was higher for men, even after differences in case-mix variables between genders were considered.
