Since each failed hip replacement has a different reason for its failure, preparing for the revision hip replacement is also going to be unique. Specialized CAT scans or MRI tests may be needed to evaluate bone loss around the current implant or position of the prosthesis relative to the normal anatomy. Various laboratory or nuclear scans to check for infection may be indicated such as CBC, CRP, Sed. Rate or Bone Scan. An aspiration of the hip joint may yield fluid that can be analyzed by cell count and culture. Finally, consultations with other medical or surgical specialists may be required to evaluate the medical condition or special circumstances of the patient prior to surgery to optimize the outcome.

As this resorption continues over time, the components reach a tipping point where the bone can no longer hold the prosthesis solidly and it starts to move within the bone. This is when the pain typically starts to become problematic. Early on the pain is often just with start up, like when getting up from a chair or out of bed in the morning and will improve as walking continues. Later in the process, the pain can be constant, even when at rest.

the ball and supports the new hip joint
A fracture may occur to the tube-like femur bone within which is fixed the femoral prosthesis with either bone cement or biologic attachment, or to the supporting bone of the pelvis to which is fixed the acetabular prosthesis. There is a wide variety of fracture patterns which occur, each having many possible solutions. A patient’s age, activity level and overall health will be weighed along with the various options to repair a fracture around a hip replacement.
Hip Replacement : Manufacturers ..
The prevailing principal in dealing with any fracture around the hip is to gain stability of the fracture and then gain stability of the hip replacement. Both the bone and the prosthesis must be stable to allow any weight bearing. It is rare that full weight bearing is allowed before the fracture is healed. In addition, if the prosthesis comes loose from the fractured bone the surgeon will typically try to bypass the fractured area of the bone to obtain firm fixation on bone further down the shaft. On very rare occasions it may be necessary to replace most of the shattered femur with a very large hip replacement prosthesis referred to as an oncologic prosthesis, one that is used in cases where a tumor has destroyed the bone.
What Type of Hip Replacement Implant Is Best? - …
For a hip replacement to function well, the ball must be retained within the socket at all times. Several factors must work in concert to keep this mechanical relationship intact, including proper alignment of the acetabular prosthesis (the socket) and the femoral prosthesis (articulating ball part). In addition, the muscles that attach to both the pelvis and the femur must be strong and able to withstand pressure. Sometimes the muscles of the elderly patient are quite weakened with age or health related issues and are unable to hold the ball in the socket.
