The National Institute for Clinical Excellence (NICE) published the guidelines on the selection of prostheses for primary hip replacement in 2000. They supported the use of cemented hip prostheses to the exclusion of uncemented and hybrid implants. The information from the Trent (and Wales) Regional Arthroplasty Study has been examined to identify retrospectively the types of hip prostheses used between 1990 and 2005, and to assess the impact that the guidelines have had on orthopaedic practice.

The results show that the publication of the NICE guidelines has had little impact on clinical practice, with the use of uncemented prostheses increasing from 6.7% (137) in 2001 to 19.2% (632) in 2005. The use of hybrid prostheses has more than doubled from 8.8% (181) to 22% (722) of all hips implanted in the same period. The recommendations made by NICE are not being followed, which calls into question their value.

We determined the rate of contamination of donated femoral heads at primary hip arthroplasty within a single region between July 1992 and July 2001. We established the null hypothesis that culture results played no role in predicting early failure of the joint because of infection.

The rate of contamination was 9%. A positive culture, at the time of retrieval, was found in 367 of 4045 femoral heads. Coagulase-negative staphylococcus was isolated in 77% of the positive cases. At a minimum follow-up of one year, there was no statistically significant difference in the rate of complications or of revision of age-matched patients whose femoral heads had a positive culture compared with those whose femoral heads were sterile.

Our findings confirm that culture of the femoral head plays no part in determining future failure of joint replacement in the donor.
