Partial Hip Replacement in Gilbert AZ
With a partial hip replacement, also called a hemiarthroplasty, only the patients femoral head (top of thigh bone) is replaced. The prosthetic component will rotate in the natural hip socket. This procedure is used for patients who do not need replacement of the joint socket (acetabulum).
How is the partial hip replacement different from total hip replacement?
The partial hip replacement surgery is less invasive than total hip replacement. With the partial procedure, only the ball of the femur must be replaced, and the joint socket is left alone. This surgery is used for patients who require replacement of the femoral head.
What are the reasons for a partial hip replacement?
Breaking or fracturing a hip can lead to breaks through the femur, which often displaces the femoral head. When the fracture occurs within the hip joint, it is called a femoral neck fracture. The upper portion of the femur is surrounded by muscle, and it has better blood supply than the neck. The partial hip replacement is used to repair damage that occurs after these injuries. A fracture of the femoral head or neck can lead to significant pain and loss of normal function.
Usually, patients who are good candidates for a partial hip replacement are those who have no significant underlying arthritis and people with healthy cartilage. A partial hip replacement is seldom used for patients with serious hip damage. Another use of a partial hip procedure is to repair damage in patients who already have a total hip replacement.
Can elderly people have this procedure?
Intracapsular fractures of the femur account for the majority of fractures in older patients. The goal of surgery is to return the patient to his/her pre-fracture functional state. Partial hip replacement was studied in older people in a recent clinical study. Researchers found that all study participants returned to their pre-fracture level of activity after the procedure. In addition, they found that hemiarthropasty was a viable option for people age 70 years and older.
How do I prepare for surgery?
Before hip surgery, you need to arrange someone to drive you home from the hospital, and have someone ready to stay with you for a few days. You will need to prepare your home for discharge. Some things to do include:
- Remove all loose cords and rugs from walking areas.
- Secure safety handrails in bath/shower and along stairways.
- Have pre-made meals and drinks available.
- Have a firm recliner chair or chair with ottoman.
- Purchase a raised toilet seat.
What can I expect during recovery?
After a partial hip replacement, a nurse monitors you in the recovery room for 45-75 minutes. Once you are stable and awake, you will be moved to a room or discharged home. Discharge depends on your unique situation, your health status, and the surgeon’s preference. You may need to stay in the hospital for 1-2 nights. You will begin passive range of motion exercises with the help of a physical therapist, and nurses administer pain medications to ease postoperative pain.
Once you are home, you must keep the incisions clean and dry, and avoid soaking in a tub or pool until wounds are healed. Expect to use a walker or crutches for a few days. Physical therapy is used to improve hip strength, flexibility, and range of motion. The Mesa orthopedic surgeon encourages frequent movement to prevent blood clots and improve recovery.
