A hip replacement reconstructs the hip joint, replacing the ends of the bones, cartilage, and reattaching tendons. The surgery uses metal, ceramic, or plastic parts which restore the ball at the top of a person’s thigh bone, also called a femur, and resurfaces the hip socket area of the pelvic bone. A camera is used to guide the surgeon’s actions when repairing the damaged cartilage. Replacement joints are attached to the bones using cement or a special coating. Cemented joints are secured to the present bone using a form of glue. Uncemented joints are fastened to the joint using a porous coating, which is designed to allow the bone to adhere to the artificial joint. Over time, the bone grows over the artificial joint and grows into the gaps of the porous coating.
Hip pain becomes more common with age and it's also more common among people who stand for long periods of time, men and women who are obese, and people who perform a great deal of heavy lifting.
Hip pain can be caused by many factors including:
- Arthritis (osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis)
- Avascular necrosis
- Childhood hip diseases or deformities
- Joint deformity and dysplasia
- Ligament, tendon, or muscle problems
- Nerve impingement in the lower back
- Bone diseases or cancer
- Repetitive stress
