Abstract

Purpose
To evaluate the clinical and radiological outcomes of bipolar hemiarthroplasty using a polished cemented femoral stem for intertrochanteric fractures in elderly patients.
Materials and Methods
From July 2005 to May 2015, 48 patients diagnosed with intertrochanteric fractures underwent bipolar hemiarthroplasty. The mean age and follow-up period were 80.5 years and 30.5 months, respectively. The postoperative results were evaluated clinically and radiologically.
Results
The mean operation time was 100 minutes (range, 90-120 minutes), and the mean amount of blood loss was 334 ml (range, 170-500 ml). At the last follow-up, the mean Harris hip score (HHS), visual analogue scale (VAS), and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were 82.2 (range, 76-90), 0.8 (range, 1-3), and 36 (range, 30-40), respectively. Walking was initiated using a walker for partial weight-bearing, and the mean walking time was 5.8 days (range, 3-14 days). Ambulatory ability was restored to a walking state before the injury in 36 cases (75.0%), and wheelchair ambulation was possible in 12 cases (25.0%). The instrumental activities of daily living (IADLs) were 17 patients (35.4%), and the basic activities of daily living (BADLs) were 31 patients (64.6%).
Conclusion
Polished cemented bipolar hemiarthroplasty can achieve secure fixation with no postoperative thigh pain. Restoring the preoperative walking ability will be more helpful for intertrochanteric fractures in elderly patients.
