This study evaluated the effectiveness of bipolar hemiarthroplasty with a cementless femoral stem for hip fractures in patients older than 70 years with osteoporosis.

This study examined 84 hips with osteoporosis that are available to follow up of more than 2 years, between July 1997 and May 2006. The clinical evaluation was carried out using the Koval classification before the fracture and at the last follow-up, and the Harris hip score at the last follow up. The radiological evaluation was carried out using the plain radiographs.

The average follow up period was 31.4 months. The Koval classification was as follows: recovery to the condition before the fracture in 25 cases (30.1%), degradation by 1 class in 56 cases (67.5%) and degradation by 2 classes in 2 cases (2.4%). The Harris hip score was 82.7 points at the last follow-up. One case (1.2%) showed cortical hypertrophy and all cases showed stable insertion of the femoral stem.

Bipolar hemiarthroplasty with a cementless femoral stem is effective and satisfactory, both clinically and radiologically, for the treatment of elderly patients with fractures around the hip.
