We report serum metal ion level data in patients with unilateral and bilateral hip resurfacing over a ten-year period. In these patients there is an increase in both cobalt and chromium levels above the accepted reference ranges during the first 18 months after operation. Metal ion levels remain elevated, but decline slowly for up to five years. However, the levels then appear to start rising again in some patients up to the ten-year mark. There was no significant difference in cobalt or chromium levels between men and women. These findings appear to differ from much of the current literature.

The clinical significance of a raised metal ion level remains under investigation.

We compared the success of the screening programmes for congenital dislocation of the hip in two hospitals in the same district, as applied to 68,861 live births over 11 years. Both used only clinical tests on new-born infants. Screening was less successful when the tests were done by junior paediatric physicians than by senior physiotherapists supervised by an orthopaedic surgeon. Clinical screening can be highly effective provided that all babies are screened at birth, and high-risk cases are followed up by a properly trained team with a well-designed protocol.
