Metal Bearings: Hip Resurfacing

The Birmingham Hip Resurfacing (BHR), designed by Derrek McMinn, and Conserve Plus (C+) are used in our clinic. These prostheses are conform with the mentioned philosophy concerning young patients.

For development and technical specifications,see www.hipresurfacing.com. Important to mention is the fact that this prostheses containing high-carbides on the metal surface, all necessary to obtain an ideal low wear friction couple! The theoretical advantages of the metal-on-metal articulation are :

The bad reputation of the resurfacing technique in the past, namely the teflon prosthesis of Charnley and metal- on-polyethylene prosthesis of WagnerWagner or Tharies prosthesis, is based on failure of the design and material properties of the implants, rather than failure of the resurfacing concept.
Due to a perfect operation technique, an up-to-date knowledge and fabrication of metal-on-metal articulations, the Resurfacing technique is doing extremely well with clinical and radiological follow-up for more than 10 years.

Indications for Resurfacing

Contraindications:

In these cases a modular big ball head can be used with a stemmed femoral prosthesis with the same metal-on-metal properties as a resurfacing, and big ball head advantages. See also “big ball heads”, and “contra-indications”. A ceramic-on-ceramic large ball head (36 mm) is another possibility.
