Osteoarthritis of the Hip
Osteoarthritis, also called degenerative joint disease, is the most common form of arthritis. It occurs most often in older people. This disease affects the tissue covering the ends of bones in a joint (cartilage). In a person with osteoarthritis, the cartilage becomes damaged and worn out causing pain, swelling, stiffness and restricted movement in the affected joint.
Hip bursitis is a painful condition caused by inflammation of a bursa in the hip. Bursae are fluid- filled sacs present in 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. This condition is mainly caused due to strain on the tendons which may be due to overuse, or biomechanical problems.
Femoroacetabular impingement (FAI) is a condition where there is too much friction in the hip joint from bony irregularities causing pain and decreased range of hip motion.
Hip pain, one of the common symptoms that patients complain of, may not always be felt precisely over the hip joint. Pain may be felt in and around the hip joint and the cause for pain is multifactorial. The exact position of your hip pain suggests the probable cause or underlying condition causing pain. Pain felt inside the hip joint or your groin area is more likely to be because of the problems within the hip joint.
Hip fracture is a break that occurs near the hip in the upper part of the femur or thighbone. The thighbone has two bony processes on the upper part - the greater and lesser trochanters. The lesser trochanter projects from the base of the femoral neck on the back of the thighbone. Hip fractures can occur either due to a break in the femoral neck, in the area between the greater and lesser trochanter or below the lesser trochanter.
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 is surrounded by muscles, ligaments, and tendons that support and hold the bones of the joint in place. Hip dislocation occurs when the head of the femur moves out of the socket. The femoral head can dislocate either backward (posterior dislocation) or forward (anterior dislocation).
Injury or damage to these structures can lead to a condition called hip instability. Hip instability happens when the hip joint becomes unstable causing various symptoms.
