Abstract
Cemented versus cementless Bipolar Hemiarthroplasty in treatment of Fracture neck of Femur.
Highlights
In the treatment of older patients with displaced femur neck fracture, bipolar hemiarthroplasty (BHA) is a more commonly accepted treatment, compared with internal fixation, because this modality offers advantages including earlier ambulation, a lower probability of reoperation and better functional outcomes. [1,2].The choice of surgical treatment for displaced femoral neck fractures in adults remains as controversial
According to the method of implant fixation, hemiarthroplasty prosthesis can be divided into 2 different types : cemented and uncemented hemiarthroplasty.[3]. Bipolar hemiprostheses is composed of three parts: The stem, the head and the outer shell
The vertical subsidence of the femoral stem was measured on simple X-rays taken immediately after surgery and at final follow-up, and difference between these values were compared in each group
Summary
In the treatment of older patients with displaced femur neck fracture, bipolar hemiarthroplasty (BHA) is a more commonly accepted treatment, compared with internal fixation, because this modality offers advantages including earlier ambulation, a lower probability of reoperation and better functional outcomes. [1,2].The choice of surgical treatment for displaced femoral neck fractures in adults remains as controversial now. The primary design goal of restoration of the geometry and bearing quality of the hip joint, leads to the recognition that all bipolar devices involve two primary components (femoral and outer shell ), each assembled from three elements. The femoral component consists of the following: - An element to restore the articulating surface property and geometry of the femoral head the articulation element). - An element to couple to couple the articulation element and the fixation element, and to maintain an appropriate structural relationship between them (the structural element). On the outer shell side, the acetabular component component consists of the following: - An element to restore the articulating surface property and geometry of the acetabular socket (the articulation element). - An element to couple the articulation element and the fixation element, and to maintain an appropriate structural relationship between them (the structural element).(4) On the outer shell side, the acetabular component component consists of the following: - An element to restore the articulating surface property and geometry of the acetabular socket (the articulation element). - An element to couple the articulation element and the fixation element, and to maintain an appropriate structural relationship between them (the structural element).(4)
