Hip surgery

The hip joint is a ball-and-socket joint. It is the second largest joint in the human body, connecting the torso with the legs. The hip joint consists of two bones: the pelvic bone and the femur. The acetabulum is shaped like a nut shell and is located in the pelvic bone. The femoral head, which is shaped like a ball and lies within the acetabulum, has a diameter of approximately five centimetres and is connected to the femur via the femoral neck. Both the femoral head and the acetabulum are coated with a layer of cartilage. A fibrous articular capsule surrounds the hip joint and connects the pelvic bone to the femur. This strong capsule prevents dislocation of the hip joint and ensures that synovial fluid is retained in the joint. Synovial fluid is produced by the synovial cells that line the inside of the articular capsule. The synovial fluid provides nutrients to the cartilage cells and facilitates gliding of the joint.
