The hip joint is a ball-and-socket joint that allows the movement of the joint in many different directions. The ball portion of the hip joint (femoral head) is at the upper end of the thigh bone (femur) and fits into the socket (acetabulum) of the hip bone (pelvis). The bone of the femoral head and acetabulum of the pelvis are separated by spongy material (cartilage) and by a sack of fluid (synovial fluid), both of which serve to lubricate the joint. A properly functioning hip joint is critical for normal everyday activities such as walking, running and climbing.
In an injured or diseased hip joint, inflammation causes swelling, pain, and stiffness.
Painful hip conditions can be treated in several ways including:
When a patient’s symptoms do not respond to these treatments, an Orthopaedic Surgeon may recommend hip replacement surgery with the aim of restoring mobility and relieving pain.
