The femoral head (femur head or head of the femur) is the highest part of the thigh bone (femur). It is supported by the femoral neck.
The head is globular and forms rather more than a hemisphere, is directed upward, medialward, and a little forward, the greater part of its convexity being above and in front.
The femoral head's surface is smooth. It is coated with cartilage in the fresh state, except over an ovoid depression, the fovea capitis, which is situated a little below and behind the center of the femoral head, and gives attachment to the ligament of head of femur.
The thickest region of the articular cartilage is at the centre of the femoral head, measuring up to 2.8 mm.
The diameter of the femoral head is usually larger in men than in women.
The fovea capitis is a small, concave depression within the head of the femur that serves as an attachment point for the ligamentum teres (Saladin). It is slightly ovoid in shape and is oriented "superior-to-posteroinferior. (Cerezal)" This orientation might be favorable for the tensed fibers of the ligamentum teres. The fovea capitis is located "slightly posterior and inferior to the center of the articular surface of the femoral head (Cerezal)" Unlike the head of the femur, the fovea capitis lacks any hyaline cartilage. The fovea capitis may contain vascular canals in two-thirds of individuals, but "their contribution to femoral head vascularity varies. (Cerezal)"
If there is a fracture of the neck of the femur, the blood supply through the ligament becomes crucial. The head of the femur is relevant to orthopedic surgery because it can undergo avascular necrosis and consequent osteochondritis dissecans. The femoral head is removed in total hip replacement surgery.

The basis for a mechanical description of the musculoskeletal system are presented. This description is based on the concepts of solid mechanics, physiology and anatomy of the musculoskeletal system.
L'acétabulum (ou cotyle ou cavité cotyloïde selon l'ancienne Nomenclature anatomique) est la surface articulaire excavée de l'os coxal chez les tétrapodes. L'acétabulum est situé sur la face latérale de l'os coxal à la jonction de ses trois os constitutifs : l'ischium en arrière, l'ilium au-dessus et le pubis en avant. C'est une surface articulaire très excavée limité par un rebord saillant : le limbus de l'acétabulum.
vignette|Vue en coupe de la cuisse montrant le fémur (terminologie latine). Le fémur est l'os long constituant le squelette de la cuisse . Il s'agit de l'os le plus long, le plus lourd et et le plus solide (quand on prend en compte sa résistance aux contraintes mécaniques, contraction des muscles...) du corps humain. Dans la position debout anatomique, le fémur n'est pas vertical.
In vertebrate anatomy, hip (or coxa in medical terminology; : coxae) refers to either an anatomical region or a joint. The hip region is located lateral and anterior to the gluteal region, inferior to the iliac crest, and overlying the greater trochanter of the femur, or "thigh bone". In adults, three of the bones of the pelvis have fused into the hip bone or acetabulum which forms part of the hip region. The hip joint, scientifically referred to as the acetabulofemoral joint (art.

The aim of this study was to analyze the accuracy of bone pose estimation based on sub-clusters of three skin-markers characterized by triangular Cosserat point elements (TCPEs) and to evaluate the capability of four instantaneous physical parameters, whic ...
Purpose In case of residual hip dysplasia (RHD) in children, pelvic radiographs are sometimes insufficient to precisely evaluate the entire coverage of the femoral head, when trying to decide on the need for further reconstructive procedures. Methods This ...

Bone marrow adipocytes (BMAds) constitute the most abundant stromal component of adult human bone marrow. Two subtypes of BMAds have been described, the more labile regulated adipocytes (rBMAds) and the more stable constitutive adipocytes (cBMAds), which d ...
