Revision Hip Replacement

Revision Hip Replacement

Over time, the original components of a hip replacement procedure can wear and loosen from bone surfaces. A revision hip replacement involves an operation to replace some or all of the original prosthetic components with new ones. The complexity of your revision surgery depends on the amount of loosening or damage that has occurred to bone surfaces, and the specialized components and bone graft material that may be required to rebuild the hip joint.

Step 2: Procedure

Your anesthesiologist will decide whether to utilize general or regional anesthesia. In this hip replacement procedure, the previous components are eliminated along with the bone surfaces that have been cleaned and rebuilt as a way to prepare them for replacement components. A new metallic socket is connected to the acetabulum, or hip socket, via cement or screws. After that, a spacer is inserted between the prosthetic ball and socket to permit smooth gliding movement. A new implant stem is cemented or ‘press fit’ to the femur, or thigh bone. At last, a brand new metal or ceramic ball is fastened to the conclusion of the femoral stem.

Step 3: Risks

Risks connected with revision processes generally are greater than with primary hip replacement surgery since the surgery is longer and more complex. Complications may include infection, blood clots, nerve injury, and the difference in leg length. Dislocation, implant loosening, or additional wear might happen through recent years.

Step 4: Recovery & Results

A revision hip replacement is a significant surgery that needs an overnight stay and a prolonged recovery period, which may take a few weeks. Sutures are removed approximately ten days after the operation. Exercise is critical to your recovery, and also a progressive walking program could be advised to improve your mobility. Moreover, a physical therapist might help you to restore movement, strength, and function. Within 3 to 6 months, you should be able to resume normal household activities. While your new prosthesis might feel a little odd at first, this will diminish with time, and most patients undergo almost complete relief from pain.

TOTAL HIP REPLACEMENT (THR)

The total hip arthoplasty is a surgical procedure performed to remove and replace the arthritic hip joint surface by artificial prosthesis to reduce pain and improve function. The worn-out or damaged cartilages and bones of hip joint is replaced with parts constructed with materials like titanium, cobalt-chromium, ceramics, and very hard plastics.

The hip prosthesis is made up of two parts a stem and a socket. The stem fits inside the thighbone (femur) and the socket or cup fits into the acetabulum of pelvis. A ball (head of femur) fits between socket and stem.

The two most common type of prosthesis are cemented prosthesis and uncemented prosthesis. The cemented prosthesis is attached to the bone with surgical cement while the uncemented prosthesis is fixed by press fit primarily and secondary bony ingrowths on the porus surface of metal implant over time. Sometimes combination of both the techniques can be done.

Procedure:

• A prosthetic socket is implanted in order to replace the damaged acetabulum also called socket present in the pelvic bone
• The arthritic head of the femur is removed and the femoral metal stem is implanted into the proximal femur either by cement or press-fit. A metal or ceramic prosthetic ball fits into stem taper, in order to recreate the natural hip joint.
• A ceramic or plastic spacer is inserted between artificial the ball and socket to enable smooth gliding movements.

Partial hip replacement (Bipolar Hip Surgery)

Partial hip replacement also called as hemiarthroplasty is a surgical procedure recommended for patients with fracture head or neck of femur. The femoral head or ball is replaced with a metal prosthesis. The socket is not replaced in hemiarthroplasty while against the total hip; both femoral head and socket are changed. Partial hip replacement is not suggested as a treatment for any arthritis hip disease since arthritis involves both socket and head of the hip joint.

The choice of surgery is subjectively decided by the treating doctor. Patients with low demand in quality of life and with more comorbid conditions are the candidate for partial hip replacement.
