Current attitudes to total hip replacement in the younger patient: results of a national survey.

A postal questionnaire was sent to all practicing consultant orthopaedic surgeons in the UK seeking information regarding their usual total hip replacement practice, the age at which they would define a patient as falling into the 'young hip group' and whether this might modify their practice. In particular, in the 'younger' age group, we were interested in the frequency of usage of uncemented implants, the choice of implant and the bearing surfaces. Of 1242 surgeons surveyed, we had a response from 935 who currently undertake total hip arthroplasty. Their responses confirm that approximately 60,645 total hip replacements are performed annually in the UK of which 9,376 are performed in the younger age group (mean age 57.5 years). As with our previous survey, the most popular prosthesis in the 'older' age group overall was the Charnley (51%) followed by the Exeter (15%). These implants also proved to be the most popular in the 'younger' age group (40% Charnley, 18% Exeter), with 75% of surgeons choosing a cemented stem, and 65% also opting to cement the socket. 23% of surgeons used hydroxy-apatite coated implants on both the femoral and acetabular sides of the joint. Stainless steel remained the most popular choice of femoral head bearing surface (42%) followed by chrome-cobalt (33%) and ceramic (25%). On the acetabular side, high density polyethylene predominated--accounting for 95%, with only 3% using chrome cobalt and 2% ceramic. There would appear to be a remarkably conservative attitude among British surgeons, the majority of whom prefer to stick with tried and tested cemented femoral implants when dealing with the younger patient. There are a small number of uncemented acetabulae and the hybrid configuration. Hydroxy-apatite coatings seem to be the most popular choice for the non-cemented prostheses. Ceramic femoral heads are used more frequently than the ceramic acetabular bearing, and equally metal/metal bearings remain infrequently used.
