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.

Aims

Despite multiple trials and case series on hip hemiarthroplasty designs, guidance is still lacking on which implant to use. One particularly deficient area is long-term outcomes. We present over 1,000 consecutive cemented Thompson’s hemiarthroplasties over a ten-year period, recording all accessible patient and implant outcomes.

Aims

The aim of this study was to report the three-year follow-up for a series of 400 patients with a displaced intracapsular fracture of the hip, who were randomized to be treated with either a cemented polished tapered hemiarthroplasty or an uncemented hydroxyapatite-coated hemiarthroplasty.

Introduction. Orthopaedic surgeons are frequently asked to perform a revision total hip arthroplasty (THA) in patients over 80 years of age. Our objective was to evaluate the outcomes after revision THA in patients 80 years or older and compare them to a cohort of patients less than 80 years of age. Methods. We reviewed all revision THAs performed in our institution from 3/1996 to 12/2008. We compared intra- and post-operative complications (medical and orthopaedic), mortality, clinical outcomes and patient satisfaction between the two age groups. Peri-operative information and complications were collected prospectively, and clinical outcome data were obtained both pro- and retrospectively. The Merle d'Aubigné score, Harris Hip score, general health (SF-12) and patient satisfaction (visual analog scale) were assessed. Results. Overall, 325 revision THAs were included, 84 (25.8%) in patients 80 years and 241 in patients <80 years. In both groups the reason for revision was aseptic loosening in 62% of the patients (mean interval primary THA - revision 142 vs. 97 months). The older group was more often revised for periprosthetic fractures and recurrent dislocation. Mean follow-up time was 4.3 years. Mortality (80 vs. <80 years) was 6% vs. 0% 3 months postoperative, 9.5% vs. 1.2% 1 year postoperative, and 31% vs. 8.3% 5 years postoperative. 3 (3.6%) re-revisions were performed in patients 80 years compared to 24 (10%) in the younger group. Postoperative medical complications developed in 22.6% compared to 6.6% in the younger group. There were one infection and 13 dislocations in patients 80 years vs. 12 infections and 22 dislocations in the other group. The Merle d'Aubigné score improved from 9.6 to 13.7 (p=0.001) in patients 80 years or older vs. 10.3 to 14.3 (p<0.001), and the Harris Hip score at last follow-up was 74.2 vs. 78.5. Patient satisfaction was significantly higher in the older group (8.4 vs. 7.5, mean difference 0.9, 95% CI 0.2;1.8). Conclusion. Revision THA in patients over 80 years was associated with substantial clinical improvement, and patient satisfaction was greater than among the younger group. However, the medical complication rate and the 3-months-mortality were substantially higher

Background. Metal on metal hip resurfacing has become popular worldwide for younger patients because of perceived advantages in function and ease of revision, due to bone conservation. Joint Registry data have shown increased risk of early failure, particularly in younger females. There have been few studies comparing the outcome of resurfacing to cemented total hip arthroplasty (THA). Methods. 715 Hip Resurfacings (HR) performed between 2000 and 2010 with up to 10 years follow-up were compared with 2210 Exeter cemented Total Hip Arthroplasties (THA) performed for all diagnoses during the same period within our region. Survivorship was recorded using revision for any cause as the end point. Harris Hip Scores were collected pre-operatively and at 1,3,5 and 7 year review. Prospective independent analysis was carried out using Kaplan Meier survivorship, and non-parametric testing to investigate the effect of age (under 55 and over 55) and gender on revision rate and Harris Hip Score. Results. Over the 10 year period survival of Exeter THA was better than HR overall. Revision rate 2% for THA and 7% for HR; P < 0.0001. There was no significant difference in risk of revision between THA and HR in males at any age. In females there was a significantly increased revision rate with HR. Under 55 Revision rates: THA 0%; HR 6.7%. 55 & over Revision rates: THA 1.3%, HR 5.9%, P < 0.0001. Harris Hip Scores were significantly better overall in the HR group. Sub-group analysis showed that Harris Hip Scores were not significantly different for males under 55. In all other groups (males over 55 and females under and over 55) Harris Hip Scores were better after HR compared with THA. Conclusions. In this series survivorship and functional scores for HR are at least as good as for THA in males. The increased risk of revision after HR in females should be weighed against advantages of bone conservation and better post-op hip scores

British Orthopaedic Association (BOA) Guidelines recommend clinical and radiological follow-up after Total Hip Arthroplasty (THA) at 1 year, 5 years and every 5 years thereafter to detect asymptomatic failure. To evaluate the importance of routine follow-up appointments (OPAs) in detecting failing implants the presentation of patients undergoing revision THA was reviewed. 176 patients who received 183 first-time revision THAs over a seven-year period (2003-2010) were identified from an arthroplasty database. A preliminary study sampled 46 THAs in 45 patients. Retrospective chart review recorded symptoms and mode of presentation. Follow-up OPA costs were calculated to estimate savings. All patients had symptoms at the time of revision (pain 96%, decreased mobility 76%, limp 35%, stiffness 26%, night pain 24%). Route of presentation was 80% new referrals (GP 63%, in-patient 9%, A&E 4%, Rheumatology 4%) vs 20% routine orthopaedic follow-up. The minimum cost for a routine follow-up OPA was £35. Assuming discharge after the earliest review when the patient has returned to full normal activities the estimated saving for the 2009 cohort of 377 primary THAs performed in our hospital is £13195 at 1 year and £52780 over the lifespan of the implants (assuming average 15 year survival). Following uncomplicated primary cemented THA in our hospital asymptomatic implant failure is unlikely. Symptomatic patients tend to present mainly to their GP and other specialities, rather than orthopaedic follow-up OPAs. Early discharge after return to full normal activities would be safe and lead to significant financial savings

Aims

Currently, periprosthetic fractures are excluded from the American Society for Bone and Mineral Research (ASBMR) definition of atypical femoral fracture (AFFs). This study aims to report on a series of periprosthetic femoral fractures (PFFs) that otherwise meet the criteria for AFFs. Secondary aims were to identify predictors of periprosthetic atypical femoral fractures (PAFFs) and quantify the complications of treatment.

Aims

This study describes and compares the operative management and outcomes in a consecutive case series of patients with dislocated hemiarthroplasties of the hip, and compares outcomes with those of patients not sustaining a dislocation.

Aims

Complex displaced osteoporotic acetabular fractures in the elderly are associated with high levels of morbidity and mortality. Surgical options include either open reduction and internal fixation alone, or combined with total hip arthroplasty (THA). There remains a cohort of severely comorbid patients who are deemed unfit for extensive surgical reconstruction and are treated conservatively. We describe the results of a coned hemipelvis reconstruction and THA inserted via a posterior approach to the hip as the primary treatment for this severely high-risk cohort.

Aims

Periprosthetic femoral fractures (PFF) following total hip arthroplasty (THA) are devastating complications that are associated with functional limitations and increased overall mortality. Although cementless implants have been associated with an increased risk of PFF, the precise contribution of implant geometry and design on the risk of both intra-operative and post-operative PFF remains poorly investigated. A systematic review was performed to aggregate all of the PFF literature with specific attention to the femoral implant used.
