Can you have a CT scan with a hip replacement?
Although some old MRI scanning equipment may not be compatible with your prosthesis, the majority of MRI scanning equipment today is safe and compatible with hip replacement parts. You also may have a CT scan of any part of your body after a hip replacement.
What is the difference between a total hip arthroplasty and a bipolar hip arthroplasty?
Total Hip Arthroplasty is reportedly superior to Bipolar Hemiarthroplasty in terms of hip pain, function and reoperation rate. Total Hip Arthroplasty has a higher rate of dislocation rate than Bipolar Hemiarthroplasty.
What is a bipolar hip replacement?
This surgical procedure replaces the head of a damaged femur with an implant designed to stabilize the femur and restore hip function. Unlike total hip replacement, in which both the ball of the femur and the hip socket are replaced, in this procedure, only the ball is replaced.
What is the difference between unipolar and bipolar hemiarthroplasty?
Unipolar prostheses has a one-piece design where the hip movement occurs between the prosthesis and the acetabulum (hip socket). A bipolar prosthesis has an additional artificial joint between the two components of the prosthesis.
What is particle disease?
Particle disease is a rare lesion that results from an inflammatory response due to wear debris-induced osteolysis following arthroplasty. Particles resulting from the wear debris cause macrophage activation and phagocytosis. Particle disease often leads to joint loosening and implant failure.
What is bipolar prosthesis?
Are there hip precautions with bipolar hemiarthroplasty?
Hip precautions are unnecessary after hemiarthroplasty, cost money both in therapist time and equipment provision and increase the length of hospital stay. Nevertheless, they continue to be used by three-quarters of trauma hospitals in England.
How long does a bipolar hip replacement last?
A successful hemiarthroplasty should last about 12 to 15 years or more.
Why do bipolar patients need hip replacements?
Conclusions: Bipolar hip hemiarthroplasty is a treatment option in acute surgery for proximal femoral fractures. Its advantages include less stress and strain for the patients than in total hip arthroplasty, and greater stability and lower risk of protrusion into the acetabulum than in classical hip hemiarthroplasty.
What is modular bipolar hemiarthroplasty?
Hemiarthroplasty using modular head partial prostheses is a common surgical procedure used to treat elderly patients with femoral neck fractures. These prostheses can be inserted with or without bone cement.
What is periprosthetic lucency?
Periprosthetic lucencies 15) is a biological process that is initiated by macrophage phagocytosis of particulate debris, causing an aseptic foreign body granulomatosis [18]. The implant becomes separated from the host bone, resulting in mechanical (aseptic) loosening.
Which radiographs are characteristic of bipolar hip revision arthroplasty?
Anteroposterior (a) and lateral (b) radiographs of the right hip show a bipolar hip hemiarthroplasty with a cemented femoral component (Zimmer). Figure 16. Anteroposterior radiograph of the right hip shows a bipolar revision arthroplasty (Solution fully porous coated; DePuy) with a long femoral stem, onlay allograft, and cerclage wires.
What is bipolar hip hemiarthroplasty made of?
Bipolar hip hemiarthroplasty (,,,Figs 15, ,16) uses two components: a femoral stem with a small diameter head and a separate acetabular component made of metal shell lined with polyethylene. Two components of the bipolar hip prosthesis snap together as an articular unit.
What imaging is used to evaluate total hip arthroplasty?
Radiography is the primary imaging method for the evaluation of Total Hip Arthroplasty. This overview focusses on the normal findings and complications of cemented versus non-cemented hip arthroplasties.
Does a hybrid total hip replacement show up on radiographs?
This coating is not visible on radiographs. Hybrid total hip replacements are a combination of cement- and cementless fixation. As cemented acetabular components have a tendency to loosen over time, the combination of a cementless acetabular component with a cemented femoral component is sometimes used.
