About Revision hip replacement surgery:
Revision hip replacement surgery is the procedure in which the problematic artificial hip implant is removed and replaced with new implant. The complex and risky procedure can relieve the complications and pains to offer a second chance to restore the mobility. In the hip revision surgery, the loose, worn out, infected or painful prosthesis is removed. The goals of the surgery are to relieve the pain and improve the functioning and enhance the overall quality of life. The risk of revision surgery could be minimized by the antibiotics that can detect the infections before it spreads all over.
Reasons for Hip Revision Surgery
There are various reasons due to which you might require hip revision surgery.
- The wearing out of the prosthesis. Mostly the plastic lining of the socket wears out and requires replacement.
- Bone loss around the prosthesis is possible. Implant particles release and stimulate the bone loss around the prosthesis as the hip replacement wears out.
- The loosing of the prosthesis. With long time period, the hip implants cause pain and loosen leading to the need for revision surgery.
- The prosthesis might become unstable with recurring dislocation and pain.
- While in some cases, the prosthesis can become infected. Due to which treatment to remove the prosthesis is required following with curing of the infection and re-implanting the new prosthesis.
Risks of hip revision surgery:
Most of the patients do not face any complications after the surgery while some degree of complications could be possible. The risks that include the hip revision surgery are the infection, bleeding, fracture, blood clots, pulmonary embolism, nerve palsy, implant loosening, leg length inequality, heart attack, stroke and dislocation of the prosthesis. The potential risks and other concerns regarding the surgery need to be discussed with the doctor.
Surgical procedure of hip revision:
Revision hip replacement surgery is similar to the primary hip replacement however the procedure is more complicated and the surgery lasts longer. The details of the surgery vary from patient to patient and also depends on the type of failure of the prosthesis. A variety of techniques can be used during the surgery.
The procedure of the surgery is as follows:
- Removal of the old prosthesis (liner, cup, femoral and/or stem head)
- Preparation of the bone (femur and socket) for the new implant
- Bone grafting in areas of bone loss (if required)
Implantation of the new prosthesis
At times the hip revision surgery is required because the plastic lining of the socket is worn although the stem and socket are in good condition and well-fixed. In such circumstances the femoral head and the socket, liner is exchanged to new implants.
Most patients undergo two to four-month rehabilitation program which is supervised by the physical therapist. Weight bearing after the hip revision surgery is normally restricted for six to eight weeks. The recovery from hip revision surgery is quite variable due to the unevenness in the surgical techniques depending on the patient.
