hip replacement
Two different techniques regarding fitting implants are used for modern joint replacements. With elderly patients, it is often more advantageous to use bone cement in order to obtain optimal longevity of the prosthesis in the osteoporotic bone. The advantage of this method is that the prosthesis is made of stainless steel, and is stable from the very first day.

The acetabulum will be replaced by a cup made of polyethylene, and will also be fixed using bone cement. This method has been applied worldwide for more than 40 years and is still the “golden standard“. The connection is stable immediately. In more than 95% of cases, patients with prosthesis did not require a replacement, even after 15 years of use.

Fitting a hip prosthesis in younger patients with good bone stock may not require bone cement, as this is an established method. The implantations are fixed by being pressed or screwed into the preshaped bone. In cement free fittings, titanium implants will be used. This biomaterial shows excellent on growth. Precise fitting is mandatory, the implants have to be stable directly after the operation, then bony on growth can stabilise the prosthesis secondarily.
