Ceramic Femoral Head Prosthesis

The material of the femoral head metal ceramic was crossed with head size 32 32 36 36 mm yielding eight device groupings.

Ceramic femoral head prosthesis. Stryker says this ceramic acetabular part demonstrated significantly lower wear versus conventional plastic on metal or metal on metal joint systems in the laboratory. The cloud sign amorphous densities in the peri prosthetic tissues and the bubble sign hyper dense rounded images with a higher contour. The femoral templates show the neck length and offset for each of the head neck combinations 3 5 to 10 5mm. Following primary total hip arthroplasty with a ceramic on polyethylene articulation a 59 year old man sustains a rare fracture of the ceramic femoral head following minimal trauma after stepping down from a curb.

Imaging findings in plain films and ct studies include misalignment of the femoral head in the acetabular roof and loss of joint space suggesting wear or fracture of the prosthesis liner. Acetabular head revision the sleeved ceramic femoral head can be used on either a new pristine stem or a previously implanted stem. The zimmer m l taper hip prosthesis is available in 14 body sizes 4 0mm through 22 5mm. As a result clinical findings become much more important.

All of these parts tend to be manufactured by the same company and implanted as a set. During the procedure a low femoral neck cut resulted in a fracture of the greater trochanter which was subsequently fixed with two partially threaded screws. Only uncemented devices were evaluated. Femoral head ball.

Stryker is a leader in the worldwide market of hip replacement products. Ceramic components are said to be advanced when it comes to extending the lifetime of the implant. Femoral component include determining the anticipated size of the implant to be inserted and the location of the femoral neck osteotomy. Non traumatic fracture of a fourth generation ceramic femoral head.

The stryker v40 femoral head is causing problems for thousands of hip implant. If ceramic is used in the femoral head component of the prosthesis major prosthetic failure can occur with very subtle radiological abnormality or even normal radiographical appearance. Femoral heads can be ceramic or metal. A ceramic femoral head and a ceramic lining ceramic on ceramic in addition during june 2011 the fda approved a new ceramic on metal system.

Following the massive depuy recall of metal on metal hip implants ceramic hips are fast becoming the implant of choice. A cementless total hip arthroplasty prosthesis was implanted through a transgluteal approach. The primary outcome was all cause revision n 28 772 and the secondary outcome was dislocation within 1 year n 19 623.
