Fractures of the femoral neck treated with hemiarthroplasty. A comparative study.
BACKGROUND
Hemiarthroplasty is the treatment of choice in the management of displaced intracapsular fractures of the proximal femur in old patients with low functional demands.


OBJECTIVE
To assess the effectiveness of cementless Austin-Moore and the cemented Thompson prostheses used in the treatment of displaced intracapsular fractures of the proximal femur.


METHODS
We studied retrospectively 376 patients with fresh, displaced, nonpathological femur neck fractures. They were treated with either a cementless Austin-Moore prosthesis or a cemented Thompson prosthesis. Criteria for the choice of the prosthesis were the fracture site on the neck of the femur and the bone quality. The follow-up period was 3 to 8 years and the number of reviewed patients was 122.


RESULTS
The Thompson prosthesis group showed slightly better results. Acetabular erosion rate was significantly lower in the uncemented group while loosening rate here was significantly higher.


CONCLUSIONS
Advantages and disadvantages were identified in both groups although we believe that none of the approaches proved definitively superior to the other.
