Elementary fracture Description Associated fractures Description Posterior wall: This is the most common variety of acetabular fracture. It typically occurs due to dashboard injury; when a person travelling in a vehicle involved in a head-on collision, the force applied over the flexed knee travels along the femur bone to the head of the femur, breaking the posterior wall of the acetabulum.
Total hip replacement is most commonly used to treat joint failure caused by osteoarthritis.Other indications include rheumatoid arthritis, avascular necrosis, traumatic arthritis, protrusio acetabuli, [5] certain hip fractures, benign and malignant bone tumors, [6] arthritis associated with Paget's disease, [7] ankylosing spondylitis [8] and juvenile rheumatoid arthritis.

English: X-ray after hip replacement in a 59 year old woman who had hip osteoarthritis. It shows an intraoperative fracture of the acetabulum. The patient was advised to restrict weight-bearing to 20kg for the first 6 weeks.
Posterior dislocations is when the femoral head lies posteriorly after dislocation. [5] It is the most common pattern of dislocation accounting for 90% of hip dislocations, [5] and those with an associated fracture are categorized by the Thompson and Epstein classification system, the Stewart and Milford classification system, and the Pipkin system (when associated with femoral head fractures).
The Harris Hip Score (HHS) is a common evaluation instrument of the results of various hip disabilities and methods of treatment, especially for the assessment of hip replacement. [1] It was developed by William H. Harris in 1969 with 30 patients who had suffered a fracture of the acetabulum or a luxation of the hip. [2]
Protrusio acetabuli is an uncommon defect of the acetabulum, the socket that receives the femoral head to make the hip joint. The hip bone of the pelvic bone/girdle is composed of three bones, the ilium, the ischium and the pubis. In protrusio deformity, there is medial displacement of the femoral head in that the medial aspect of the femoral ...
Zones of a hip prosthesis, by the DeLee and Charnley system, [1] and the Gruen system. [2] After hip replacement, hip prosthesis zones are regions in the interface between prosthesis material and the surrounding bone. These are used as reference regions when describing for example complications including hip prosthesis loosening on medical imaging.
A hip fracture is a break that occurs in the upper part of the femur (thigh bone), at the femoral neck or (rarely) the femoral head. [2] Symptoms may include pain around the hip, particularly with movement, and shortening of the leg. [2] Usually the person cannot walk. [3] A hip fracture is usually a femoral neck fracture.
