Hip fractures are common injuries with complications that can be life-threatening, where femoral neck fractures are a specific type of intracapsular hip fractures. The risk of hip fracture rises with age.
Treatment is generally operative with closed or open reduction and internal fixation versus arthroplasty depending on the age, activity demands and pre-injury mobility.
Displaced intra-capsular fractures often disrupt the blood supply to the femoral head and, therefore, usually avascular necrosis occurs with fixation of these fractures.
Hemiarthroplasty is a common surgery done for displaced femur neck fractures. Hemiarthroplasty can be subdivided into Unipolar and Bipolar. Unipolar arthroplasty is more associated with a high rate of acetabular erosion.
Bipolar hemiarthroplasty can be either cemented into the femoral canal or uncemented with press-fit technique. Before surgery, the type of stem is determined according to Dorr classification of the proximal femur and cortical thickness on pre-operative radiographs.
AIM OF THE WORK:
The aim of this study was to compare the functional outcomes of cemented versus cementless bipolar hemiarthroplasty in displaced intracapsular neck of femur fractures.
