The hip is a ball and socket joint comprising of the femur (thigh bone) and the pelvic bone. The head of the femur (ball) articulates with a cavity (socket) called the acetabulum in the pelvic bone. To facilitate smooth and frictionless movement of the hip joint, the articulating surfaces of the femur head and acetabulum are covered by spongy articular cartilage. Injury, wear-and-tear and certain diseases can result in the wearing away of the cartilage tissue, causing painful rubbing of bones.
Hip implants are artificial devices that form the essential parts of the hip joint during a hip replacement surgery. The hip implants vary by size, shape, and material. Implants are made of biocompatible materials that are accepted by the body without producing any rejection response. Implants can be made of metal alloys, ceramics, or plastics, and can be joined to the bone. The metals used include stainless steel, titanium, and cobalt chrome, whereas the plastic used is polyethylene.
The hip joint is a ball and socket joint, where the head of the thigh bone (femur) articulates with the cavity (acetabulum) of the pelvic bone.
Sickle cell disease, a group of disorders that affect the hemoglobin or oxygen carrying component of blood, causes avascular necrosis or the death of bone tissue in the hip due to lack of blood supply.
The hip joint is one of the body's largest weight-bearing joints and is the point where the thigh bone (femur) and the pelvis (acetabulum) unite. It is a ball and socket joint in which the head of the femur is the ball and the pelvic acetabulum forms the socket.
Femoroacetabular impingement (FAI) is a condition where the hip bones are abnormally shaped and the ball (femur or thigh bone head) and socket (acetabulum) joint of the hip bones rub against each other due to abnormal contact. Bone spurs form around the femoral head and/or acetabulum preventing smooth gliding movement of these bones against each other. This condition can damage the articular cartilage (smooth cushioning surface of the ball and socket) or cause a tear in the labrum (soft elastic tissue which forms the socket ring) in the hip joint.

It is a ball and socket joint in which the head of the femur is the ball and the pelvic acetabulum forms the socket. The joint surface is covered by a smooth articular cartilage that cushions and enables smooth movements of the joint.
