The Birmingham Hip Resurfacing (Smith & Nephew London, UK) is the most popular hip resurfacing (HR) in the UK. However, it is now subject to two Medical Device Alerts (MDA) from the Medicines and Healthcare products Regulatory Agency (MHRA). A cross-sectional survey of primary metal-on-metal hip procedures recorded on the National Joint Registry for England, Wales and Northern Ireland (NJR) until 5th November 2013 was performed. Cost-analysis was based on an algorithm for surveillance of HR at a tertiary referral centre and followed previous MHRA guidance. NIHR NHS Treatment costs were used. The local protocol encompassed: patient outcome scoring (Oxford hip score), blood metal ion measurement (cobalt, chromium), cross-sectional imaging (MRI) and discussion at an internet-enabled multidisciplinary team meeting (iMDT) in addition to routine hip surveillance.Introduction
