Hip revision surgery begins by making an incision on the site of the old prosthesis, removing it and preparing the bone for the new implant, says Drugwatch. The surgeon then fixes the new femoral implant into place and adds bone grafts if necessary, explains SurgeryEncyclopaedia.com.
Hip revision surgery involves the removal of the old artificial hip joint including the cup, liner, stem and the femoral head. The process begins by removing the part attached to the acetabulum, according to SurgeryEncyclopaedia.com. Doctors may make use of the old incision site or make a new one when removing the joint.
The surgeon then prepares the socket and femur bones for the new implant. Once the socket is clean, the surgeon fills it with bone in particle form. The surgeon presses the new shell and liner into the acetabulum, says SurgeryEncyclopaedia.com. The doctor may recommend the patient to wear a splint or a brace after closing the incision, notes Drugwatch.
Part of the revision process involves grafting of the bone in the case where there was bone loss. The surgeon reconstructs the bone using bone grafts, screws and metallic plates, explains Drugwatch. The technique involves packing the graft bone into a canal inside the femur and holding the segments of the femur with surgical wire, according to SurgeryEncyclopaedia.com.
