A clinicoradiologic study of the Birmingham Mid-Head Resection device

This is a 1.2- to 5.3-year survival and clinicoradiologic study of patients with the Birmingham Mid-Head Resection (BMHR) device (Smith & Nephew Orthopaedics, Warwick, United Kingdom). Sixty consecutive hips implanted with this device between 2003 and 2007 were reviewed with hip outcome questionnaires, clinical examination, and radiographs at a minimum follow-up of 1 year. There were no revisions, mechanical failures, or signs of femoral neck stress shielding. All hips were functioning well and showed no significant adverse clinical or radiographic features. Birmingham Mid-Head Replacement offers the prospect of circumventing the need for a more invasive procedure such as hip replacement in patients who would benefit from a conservative arthroplasty but lack femoral head bone quality, which is a prerequisite for a successful hip resurfacing.
