Purpose: This study evaluated the effectiveness of bipolar hemiarthroplasty with a cementless femoral stem for hip fractures in patients older than 70 years with osteoporosis.
Materials and Methods: 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.
Results: 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.
Conclusion: 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.
