The hip refers to the region of the body where the hip joint is. The hip is actually a ball-and-socket joint called the acetabulofemoral joint because it connects the femur (thigh bone) and acetabulum of the pelvis.


The hip joint bears the weight of the body’s trunk and allows us to walk, run, jump, and be mobile. Because the hip is comprised of weight-bearing bones, they are protected with a layer of cartilage, which protects the bones and allows for range of motion. The hip joint is one of the most flexible joints in the body (except for the shoulder), and is built to accommodate extreme forces during physical activity. It also plays a large role in maintaining balance.


A number of things can cause hip pain, but one of the main causes is osteoarthritis. Other causes include rheumatoid arthritis, injury to a tendon, or a pinched nerve. Often, pain symptoms can be managed with NSAIDs or steroids. In more severe cases, a hip replacement might be necessary.
