Femoral heads of different designs were prepared by using stainless steel alloys, cobalt alloys, titanium alloys, alumina, zirconia and ultra high molecular weight polyethylene. Due to various issues like early failure, corrosion, increased ion metal levels in blood, machining difficulty and cost, there is always scope for research for new material for hip prosthesis. In this paper, suitability of Carbon Fibre Reinforced Polyamide 12 for femoral head has been reviewed. This framework quantifies CF/PA 12 material characteristics like biocompatibility, cost effectiveness, failure mechanism, corrosion and wear with respect to its use as femoral head. In this review, the adequacy of CF/PA 12 as a femoral head is discussed considering essential parameters.
