AbstractNonsteroidal anti-inflammatory drugs (NSAIDs) may prevent heterotopic ossification after total hip arthroplasty (THA). Cyclooxygenase 2 (COX-2) inhibitors may minimize side effects. The goal of this review was to compare the effectiveness and side effects of the perioperative use of selective COX-2 inhibitors with those of conventional NSAIDs in patients undergoing THA. We followed the systematic reviews' updated methods of the Cochrane Collaboration Back Review Group and searched MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials. We identified all randomized controlled trials until April 2009 enrolling THA patients and comparing COX-2 inhibitors to NSAIDs. We assessed their methodological quality and extracted data. Five randomized controlled trials were included. Prevention of heterotopic ossification and side effects with COX-2 inhibitors were significant in 2 studies. Discontinuation for side effects was not significant. COX-2 inhibitors do not prevent heterotopic ossification after THA significantly better than conventional NSAIDs, while they are advantageous regarding side effects.Copyright 2011, SLACK Incorporated.
