Experience with the Exeter total hip replacement since 1970.

Abstract

The satisfactory long-term radiographic appearances with the use of the collarless, smooth, polished, tapered stem encourage its continued use. With the same stem geometry shortly to become available with interchangeable heads, the capacity for the surgeon to change the bearings when polythene wear starts to become marked should address what certainly will emerge as one of the major long-term problems of total hip arthroplasty.
