Abstract
From 1988 through 1993, 75 hips in 75 patients had Bipolar endoprosthesis (BEP) for fractures of the femoral neck. Until 1990 we used uncemented Harris/Galante porous stems (Zimmer) in 35 patients (uncemented group). Then cemented Centralign System stems (Zimmer) were used in 40 patients (cemented group). The mean age at BEP was 75.3 years in the uncemented group and 79.0 years in the cemented group. The average postoperative follow-up period was 4.8 years in the uncemented group and 2.7 years in the cemented group.
The rate of postoperative thigh pain and the duration of hospitalization were compared between these two groups. We observed increases in the rate of thigh pain and in the duration of hospitalization after uncemented BEP although the differences were not significant.
It may be advantageous to use cemented BEP for fractures of the femoral neck in aged patients.
