hip bipolar replacement
Bipolar hip surgery is the same as a hip replacement?
Make a report … any useful information … thanks!
Not quite. This should explain it. http://www.totaljoints.info/prostheses_for_other_hip_replace.htm scroll down for a picture. The extra large heads bipolar hemiprosthesis metallic femoral diameters between 48 to 60 mm. The oversized ball has two layers: the outer metal layer is structured with the joint cartilage and the layer polyethylene inner articulates with a conventional femoral ball. The stem of the femoral component is identical to the mother of the conventional total hip prosthesis. The surgeon meets the hemiprosthesis directly on the operating table. The bipolar hemiprosthesis supposed to lose the cartilage of the hip socket because it moves into "two poles": One is the movement against joint cartilage, the other is against the ball of the shaft component. The advantage of a hemi-bipolar hip prosthesis is the possibility easily change to the ordinary prosthetic total hip replacement when the patient has pain in hip hemi-arthroplasty. This is often necessary, as the cartilage joint usually does not tolerate contact with the metal surface of the hemi-prosthesis. A special indication for the use of this prosthesis is unstable total hip. Due to the large diameter of the ball of the femur, the prosthesis of hemiarthroplasty of the hip joint is very stable in the acetabulum with a condition: that the surgeon removes the component of the cup and use a ball of the femur that completely fills the bone cavity.
