There is public concern over the long term systemic health effects of metal released from hip replacement prostheses that use large-diameter metal-on-metal bearings. However, to date there has been no systematic study to determine which organs may be at risk, or the magnitude of any effect. We undertook a detailed cross-sectional health screen at a mean of 8 years after surgery in 35 asymptomat...
Historical context The concept of resurfacing the hip can be traced back to the early 1900s with the various techniques of interposition arthroplasty.1 Smith-Petersen produced a cast cobalt-molybdenum alloy (vitallium) interposition cup in 1940 as a culmination of many years work with different materials.2 Charnley experimented with a polytetrafluoroethylene (PTFE) hip resurfacing as a clear co...
The cause of fracture of the femoral neck after hip resurfacing is poorly understood. In order to evaluate the role of avascular necrosis we compared 19 femoral heads retrieved at revision for fracture of the femoral neck and 13 retrieved for other reasons. We developed a new technique of assessing avascular necrosis in the femoral head by determining the percentage of empty osteocyte lacunae p...
Few independent studies have reported the outcome of resurfacing arthroplasty of the hip. The aim of this study was to report the five-year clinical outcome and seven-year survival of an independent series. A total of 610 Birmingham Hip Resurfacing arthroplasties were performed in 532 patients with a mean age of 51.8 years (16.5 to 81.6). They were followed for between two and eight years; 107 ...
BACKGROUND Metal-on-metal resurfacing arthroplasty is an attractive alternative to conventional total hip arthroplasty in patients with osteoarthritis secondary to developmental dysplasia of the hip (DDH). The purpose of this study was to assess the mid-term clinical outcome and mid-term survivorship of Metal-on-metal resurfacing arthroplasty in patients suffering from osteoarthritis secondary ...
Consensus statement "Current evidence on the management of metal-on-metal bearings"--April 16, 2012.
a. What are the benefits (effectiveness)? MoM is currently the only technique for surface replacement. There are no polyethylene particles in pure MoM bearings that may cause osteolysis. MoM bearings produce less volumetric wear compared to conventional polyethylene. There is a reduced risk of fracture in MoM bearings compared to ceramics. Large head Total Hip Replacement (THR) (36mm head size ...
A 34-year-old woman with a benign form of osteopetrosis developed osteoarthritis of the hip. In order to avoid the difficulties associated with inserting the femoral component of a conventional total hip arthroplasty, a hybrid metal-on-metal resurfacing was performed. There were several technical challenges associated with the procedure, including the sizing of the component, press-fit fixation...
BACKGROUND AND PURPOSE Postoperative C-reactive protein (CRP) levels in serum appear to reflect surgical trauma. We examined CRP levels after 4 types of arthroplasty. MATERIAL AND METHODS We investigated 102 patients who had total knee arthroplasty (TKA), computer navigation-assisted total knee arthroplasty (NAV-TKA), hip resurfacing arthroplasty (metal on metal, MMSA) and total hip arthropla...
