%0 Journal Article %T Revision of failed hip resurfacing to total hip arthroplasty rapidly relieves pain and improves function in the early post operative period %A Nemandra A Sandiford %A Sarah K Muirhead-Allwood %A John A Skinner %J Journal of Orthopaedic Surgery and Research %D 2010 %I BioMed Central %R 10.1186/1749-799x-5-88 %X There were 12 male and 13 female patients with average time to revision of 34.4 and 26.4 months respectively. The mean follow up period was 12.7 months (3 to 31). All patients reported relief of pain and excellent satisfaction scores. Two patients experienced stiffness up to three months post operatively.Pre operative Oxford, Harris and WOMAC hip scores were 39.1, 36.4 and 52.2 respectively. Mean post operative scores at last follow up were 17.4, 89.8 and 6.1 respectively (p < 0.001 for each score). These results show that conversion of hip resurfacing to total hip arthroplasty has high satisfaction rates. These results compare favourably with those for revision total hip arthroplasty.Metal on Metal (MoM) hip resurfacing has become increasingly popular over the last decade. Data from the United Kingdom (UK) National Joint Registry [1] suggest that while hip resurfacing (HR) procedures account for approximately 10% of all hip arthroplasty procedures in the UK annually, the actual number of hip resurfacings performed is steadily increasing from 2,338 in 2004 to 5,596 in 2007 [1]. The proposed benefits of HR compared to total hip replacement include femoral bone preservation, increased stability, improved proprioception of the hip joint and technically less demanding conversion to a total hip replacement if necessary, particularly on the femoral side. This is most relevant to young, active patients.While early results of Metal on Metal hip resurfacing have been promising, complications have been reported which require revision. These include femoral neck fractures [2] and recurrent pain and effusions thought to be related to an aseptic lymphocytic vasculitis associated lesion (ALVAL) syndrome [3]. Large destructive lesions (pseudo tumors) have also been reported which lead to soft tissue loss around the hip joint[4]. While it may be relatively straightforward to revise a hip resurfacing to a total hip replacement, the results of this procedure are unknown. If there is %U http://www.josr-online.com/content/5/1/88
