Hip Joint Replacement
Hip replacement surgery is performed in cases of severe damage of the hip joint and involves replacement of the degenerated components of the hip joint with a synthetic implant to renew stability and function. This is done to repair the damaged part of hip joint that is the main source of pain and disability for the patient.
Total hip replacement surgery involves replacement of both the thigh bone (femur) and the socket with synthetic implant materials. It is a highly successful surgery that has following advantages:
- Renewed stability and function
- Increases joint mobility
- Relieves pain
- Improves working of hip joint
- Restores normal walking and other movements
- Incredibly improves quality of life of the patients
Indications for hip joint replacement
As in almost all the cases of joint replacement, the main reason for hip joint replacement too is to relieve severe pain that is limiting the daily activities of the patient. Surgeon recommends hip joint replacement in following conditions:
- Rheumatoid arthritis
- Traumatic arthritis
- Dislocation or fractures of thigh bone
- Hip joint tumors
- Hip joint pain and stiffness that disturbs night sleep and limits or prevents the normal activities like bathing, preparing meals, doing household chores, and walking
- Failure of all conservative treatment options to get relief from pain
Hip Joint Replacement Procedure
The procedure of hip replacement is performed under general or regional anaesthesia and involves removal of the degenerated cartilage and bone from the hip joint and its replacement with prosthetics. Either the hip socket (acetabulum) or upper end of the thigh bone (femoral bone) or both may be replaced during surgery.
The parts of new hip joint include the following:
Types of joint replacement depending upon prosthesis
- Cemented joint prosthesis uses fast-drying bone cement to help affix it to the bone. The procedure performed is called cemented total hip replacement.
- Uncemented joint prosthesis, sometimes called a press-fit prosthesis, is specially textured to allow the bone to grow onto it and adhere to it over time. The procedure performed is called uncemented total hip replacement.
- Hybrid hip replacement uses both cement less ( Acetabulum cup) and cemented (femoral stem ) components in prosthesis.
Prognosis of Hip Joint Replacement
Hip joint replacement is a highly successful surgery that offers excellent results and takes away most of the pain and stiffness of the joint. In cases of younger patients, replaced joint may loosen or wear & tear with time. This can happen after as long as 15 – 20 years and may need a second replacement.
