Surface replacement of the hip.

Abstract

Attempts to resurface the hip joint date back to the 1930s. Throughout the last century many designs failed due to defective materials or fixation (or a combination). The metal-on-metal designs pioneered at the end of the century appeared to herald a new era, until difficulties associated with adverse reactions to metal debris were identified. Ultimately, a much narrower range of indications emerged - large, young males appear to be the ideal recipients. Implant design features and component orientation are crucial to the survivorship of these implants.
