The hip joint is a “ball and socket” joint. The “ball” is the head of the femur or thighbone, and the “socket” is the cup-shaped acetabulum. The joint surface is covered by a smooth articular surface that allows pain-free movement in the joint.
The hip is a ball-and-socket joint made up of the head of the thigh bone or femur that acts as the ball and fits into the rounded socket of the hip bone or acetabulum. The neck of the femur is the region just below the ball of the hip joint.
Femoroacetabular impingement (FAI) is a condition characterized by excessive friction in the hip joint from the presence of bony irregularities. These cause pain and decreased range of hip motion.
Hip bursitis is a painful condition caused by the inflammation of a bursa in the hip. Bursae are fluid-filled sacs present in the joints between bone and soft tissue to reduce friction and provide cushioning during movement.
Tendons are strong connective tissue structures that connect muscle to bone. Hip tendonitis is a condition associated with degeneration of the hip tendons.
A hip labral tear is an injury to the labrum, the cartilage that surrounds the outside rim of your hip joint socket.
The hamstring is a group of three muscles that run along the back of the thigh from the hip to the knee. Hamstring injuries occur when these muscles are strained or pulled.
A hip flexor strain is an overuse injury to the flexor muscles of your hip and can range from a minor stretch injury to a complete tear of the muscle fibers or tendons.
Hip flexor pain is a distressing feeling or discomfort noted in the hip and/or groin region that can make everyday activities, such as going up and down the stairs or lifting your leg to tie a shoe extremely difficult and painful and can severely limit your activity and mobility.
The gluteus medius is one of the major muscles of the hip; essential for the movement of the lower body and keeping the pelvis level during ambulation.
Hip and groin disorders are more common in athletes. They are caused by rapid acceleration and deceleration motion.
