The hip joint is a ball-and-socket joint that connects the thigh bone (femur) to the pelvis (hip bone). It is a weight-bearing joint that plays an important role in supporting the body and allowing for movement, such as walking, running, and climbing stairs.
Some common conditions that affect the hip joint include:
- Osteoarthritis: a degenerative condition characterized by the breakdown of the cartilage that cushions the hip joint.
- Bursitis: inflammation of the bursa, a fluid-filled sac that acts as a cushion between tendons, muscles, and bones in the hip.
- Tendinitis: inflammation of the tendons that attach muscle to bone in the hip.
- Fracture: a break in the bone in the hip joint, which can occur as a result of a fall or accident.
- Dislocated hip: when the upper part of the thigh bone (femur) is forced out of the socket in the pelvis (hip bone).
- Hip labral tear: a tear in the ring of cartilage (labrum) that surrounds the hip joint, that can occur from overuse or injury.
- Snapping hip syndrome: a condition characterized by a snapping or popping sensation in the hip, caused by the tendons or muscles sliding over the joint.
- Avascular necrosis (AVN): a condition caused by a lack of blood supply to the hip bone, which can lead to bone death.
- Rheumatoid arthritis: an autoimmune disorder that causes inflammation and damage to the joints, including the hip joint.
- Osteonecrosis of the femoral head: a condition characterized by bone death of the head of the femur, caused by decreased blood supply to the area.
