Patient is a 70 year old male who came in complaining of right hip pain. He had stated that he had been experiencing this pain for a few years and that it has been worsening. He had informed at that he had received a right Total Hip Arthroplasty (THA) ten years earlier at an outside institution.
At his initial visit, it was determined that the patient had osteolysis of the right hip. To rule out any infection the patient was advised to get an aspiration of the right hip, including complete blood count (CBC), comprehensive metabolic panel (CMP), erythrocyte sedimentation rate (ESR), and C- reactive protein tests (CRP).
All test results came back negative for infection. All options were discussed at length with the patient, but he was advised to have a Revision THA due to his condition. He was informed about the increased risks and all benefits to the revision surgery. Patient had decided to have the surgery and continued to schedule for the THA Revision operation.
X-Rays show right total hip replacement with lucency around the acetabular component
X-Rays show right total hip revision during operation. Prosthesis is in good positioning
X-Rays six months post-operative show prosthesis in good positioning
Six months post right THA revision surgery patient is doing well, is weight bearing as tolerated, and has good range of motion. Upon subsequent follow ups patient continues to do well with good relief. Below are the images of various revision total hip replacement implants that may be used in revision surgeries.
Acetabular Shell
The acetabular shell fits in the cavity prepared in the acetabulum during surgery. The porous plasma coating helps in bone on-growth and the screws hold the shell in place.
The proximal part of modular femoral stem for revision hip replacement
The modular proximal part of the femoral stem in the image above allows for adjusting anteversion intraoperatively and attachment of a long stem.
The distal stem of a modular femoral component for revision hip replacement
The long splined stem fits in the proximal part of the modular femoral component. The stem transmits the load distally in the femur and the splined shape offers rotational stability.
Ceramic Head with Adapter Sleeve
Ceramic head or metal alloy heads may be used for replacement surgeries.
