A UK MDA alert issued on 7th September states that the DePuy ASR hip system has been withdrawn from the market. This follows reports of relatively poor results for the resurfacing system and should come as no surprise following earlier MDA alerts.
ASR sockets and resurfacing heads should be taken off the shelf and returned to the manufacturer. The MDA recommends that patients with implanted devices should be contacted and followed up.
Hip resurfacings and metal-on-metal bearings have been the subject of some controversy recently and it seems inevitable that the market share will decline. However, the decline in metal on metal bearing use has opened the way to other new unproven devices, with demand driven by direct to patient marketing. These include DePuy’s Delta Motion hip and Stryker’s “mobile bearing” ADM hip, both of which are said to provide advantages for younger patients. It remains to be seen whether these new devices catch on, or whether we see a return to more standard tried and tested devices.
