Comparative Study
Cementless bipolar hemiarthroplasty using a rectangular cross-section stem for unstable intertrochanteric fractures.
The purpose of this study was to compare the clinical and radiographic results for elderly patients sustaining unstable intertrochanteric fractures treated with an uncemented bipolar hemiarthroplasty using a double-tapered, rectangular cross-section stem. Thirty-seven patients (21 females, 16 males; mean age 73.5 years, range 65-88 years) who underwent bipolar hemiarthroplasty with a standard (double-tapered, rectangular cross-section) uncemented stem were followed up for a minimum of two years. At final follow-up, 27 patients (72.9%) had recovered their daily living ability (Barthel index), and 28 patients (75.6%) had recovered all walking ability at a community level (Koval's category).

Comparative Study
Incidence of adverse wear reactions in hip resurfacing arthroplasty: a single surgeon series of 2,600 cases.
A single surgeon performed 2,559 metal-on-metal hip resurfacing arthroplasties in 2,109 patients. The Corin Cormet 2000 (393 cases) and Biomet Recap implants (2,166 cases) were used in our series. In this study, the adverse wear failure (AWF) rate was 0.27%. ⋯ All had severe metallosis found at the time of revision. Six of the seven AWF cases were in women. There were no failures from pseudotumours without AWF (metallosis) in this series.
