PURPOSE: Over 30,000 hip hemiarthroplasties for neck of femur fractures are performed annually in the United Kingdom (UK). The national recommendation is via the lateral approach, to reduce the risk of dislocation, with the potential expense of reduced function and mobility post-operatively. Muscle-sparing approaches, such as SPAIRE (sparing piriformis and internus repairing externus), have been invented to address the issue of dislocation. METHODS: We performed a retrospective data collection at a single center with a high annual volume of hip hemiarthroplasties over 12 months. All patients who had hip hemiarthroplasty as their primary treatment were included. Patients who passed away and were non-ambulant before their surgery were excluded from the study. Our primary outcome was the dislocation rate and secondary outcomes were the time to mobilization after surgery and the duration of surgery. Statistical analysis was performed using XLSTAT software. RESULTS: We identified 194 cases, and these were divided into 3 groups based on the surgical approach: SPAIRE (n = 43), lateral (n = 97), and posterior (n = 54). Groups had similar demographics and a minimum 3-month follow-up after surgery. There were no dislocations in the SPAIRE group, whereas the dislocation rate for the other 2 groups was 2.5% in the lateral and 9.1% in the posterior groups at 6 months post-surgery. There was an earlier return to mobility in the SPAIRE (1.4 day) compared to the 2 other groups ( 2 days and 2.6 days). Average surgical times were very similar among all 3 groups (74 min vs. 79 min vs. 71 min). CONCLUSION The SPAIRE approach seems to be safe and provides a low risk of dislocation and good post-operative function for patients undergoing hip hemiarthroplasties.

BACKGROUND/AIMS: Several prognostic markers for heart failure (HF) have been determined but the importance of liver function tests (LFTs) remains unknown. The aim of this study was to determine the prognostic significance, if any, of abnormal LFTs in acute decompensated HF. METHODS: All adult patients (> 18 years of age) who were admitted to a community hospital with a diagnosis of acute decompensated HF during the period January 2008 to December 2009 were identified. Exclusion criteria included acute coronary syndrome, active hepatobiliary disease, renal failure (serum creatinine > or = 2 mg/dL), and malignancy. The primary end point was readmission secondary to acute exacerbation of HF. The Cox proportional hazard model was used for statistical analyses. RESULTS: Univariate analysis showed that serum total bilirubin (TB, p < 0.01), serum B-type natriuretic peptide (p < 0.05), ejection fraction (EF, p < 0.05), and heart rate (p < 0.05) were significant predictors of hospital readmission secondary to acute decompensated HF. Multivariate analysis showed that high serum TB (> 1.3 mg/dL) on admission was an independent predictor (p < 0.05) of hospital readmission secondary to HF. The 'at-risk' group-patients with serum TB > 1.3 mg/dL and/or EF < 35% on admission-had a readmission rate that was 87% +/- 20% (p < 0.05) higher than those with neither criterion. CONCLUSIONS: In patients with acute decompensated HF, elevated serum TB on admission with or without low EF (< 35%) predicts a worse prognosis and early future readmission, secondary to HF.
