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.

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.
The greater trochanter of the femur is a large, irregular, quadrilateral eminence and a part of the skeletal system. It is directed lateral and medially and slightly posterior. In the adult it is about 2–4 cm lower than the femoral head . [ 1 ]
A trochanter is a tubercle of the femur near its joint with the hip bone. In humans and most mammals , the trochanters serve as important muscle attachment sites. Humans have two, sometimes three , trochanters.
The lesser trochanter is a conical posteromedial projection of the shaft of the femur, projecting from the posteroinferior aspect of its junction with the femoral neck. [1] The summit and anterior surface of the lesser trochanter are rough, whereas its posterior surface is smooth. [1] From its apex three well-marked borders extend: [2]
The highest point of the greater trochanter is located higher than the collum and reaches the midpoint of the hip joint. The greater trochanter can easily be felt. The trochanteric fossa is a deep depression bounded posteriorly by the intertrochanteric crest on medial surface of the greater trochanter. Anterior and superior to the trochanteric ...
