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).
