CONTEXT Surface replacement of the hip is aimed especially at active patients, and it seems to achieve optimal functional results in a short time if associated with a tailored rehabilitation protocol. OBJECTIVE To assess the functional outcome in a group of active patients after hip resurfacing. DESIGN Clinical measurement and controlled laboratory study in a case series. SETTING Gait-ana...

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 revisio...

The purpose of this study was to compare clinical outcomes between ceramic-on-ceramic total hip replacement and metal-on-metal hip resurfacing arthroplasty in comparable groups of young active patients at a 3to 6-year follow-up. The first 250 patients (mean age, 49.54 years) of a series of 930 resurfacing arthroplasties were compared clinically and functionally with a series of 190 patients (me...

The Birmingham Mid Head Resection (BMHR) arthroplasty can be used as an alternative to conventional stemmed total hip arthroplasty in young patients unsuitable for hip resurfacing. This study investigated the effect of stem size on femoral neck fracture in the BMHR. Sawbones composite femurs were randomly allocated to one of the following groups: 1) Unprepared femur with no prosthesis; 2) Femur...
