Hip dysplasia is a condition which is seen in infants and young children as a result of developmental problems in the hip joint. The femur (thigh bone) partially or completely slips out of the hip socket causing dislocation at the hip joint. It is most common in first born baby with family history of the disorder.
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.
Osteoarthritis, also called degenerative joint disease is the most common form of hip 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.
