Usefulness of the Cementless Stem for the Treatment of Hip Fracture in Elderly Patients with Osteoporosis: Comparative Analysis between Cementless Stem and Cemented Stem

ABSTRACT

PURPOSE: We evaluated the usefulness of the cementless stem in treating hip fracture patients older than 70. MATERIALS AND METHODS: We studied elderly osteoporotic hip fractures in the neck and intertrochanter area who had received hip arthroplasty with over 2 years of follow up period. Among those, we analyzed the clinical and radiological results of hip arthroplasty with cemented stem (group 1) and hip arthroplasty with cementless stem (group 2). Each group was consists of fifty hips. RESULTS: The mean age at surgery was 75 years and mean follow-up period was 40 months (minimum 24 months). The admission period was 28.68+/-8.8 days for group 1 and 28.05+/-8.7 days for group 2 (p>0.05) and the average operation time was 87+/-21.2 minutes, and 80+/-17 minutes (p>0.05) and the total blood loss was 611+/-141.3 cc and 557+/-120.5 cc (p>0.05) respectively. There was no statistically significant difference in all aspects. One case of pulmonary embolism occurred in group 1. Stem loosening was not observed in both groups at the last follow-up radiologic study. CONCLUSION: The hip arthroplasty with cementless stem for the osteoporotic hip fractures showed a competent results clinically and radiologically in short term follow up as compared with the cemented stem.
