Dislocation is a frequent and costly complication of hip arthroplasty. The purpose of this study was to assess the financial impact on the treating institution of this complication in patients with primary hemiarthroplasty (HA), total hip arthroplasty (THA) and revision surgery (RTHA). Between October 2001 and August 2009, 2014 consecutive hip arthroplasties were performed at our institution, of which 87 (18 HA, 44 THA and 25 RTHA) dislocated within 6 weeks of the primary operation. The average cost of treating implant dislocation by closed reduction, open reduction or revision was assessed and expressed as a percentage cost increase compared to an uncomplicated procedure. Of the 87 dislocated implants all needed one or more closed reductions and 52 eventually required revision surgery. An early dislocation increased the cost of HA, THA and RTHA by 472%, 342% and 352%, respectively.
