Prophylactic Celecoxib Administration Is Associated With Decreased Incidence and Severity of Heterotopic Ossification After Hip Resurfacing by Direct Lateral Approach in Male Patients.

Abstract

Heterotopic ossification is a potential complication that may have a particularly higher association with hip resurfacing. The 2 current mainstays for heterotopic ossification treatment and prophylaxis are administration of nonsteroidal anti-inflammatory drugs and radiotherapy. Recent studies have determined that celecoxib is effective in heterotopic ossification prophylaxis after total hip arthroplasty. However, considering the reportedly higher incidence and severity of heterotopic ossification in these patients, relatively few studies have evaluated its role in hip resurfacing. Therefore, the authors assessed the incidence, severity, and risk factors of heterotopic ossification in patients who had hip resurfacing and did or did not receive celecoxib. Of the 198 patients, 83 received celecoxib and 115 did not. Radiographs were examined to grade heterotopic ossification using the Brooker classification system. The rate of heterotopic ossification differed between patients who did and patients who did not receive celecoxib prophylaxis (25% vs 65%, P<.001). Celecoxib was an independent predictor of decreased heterotopic ossification (odds ratio, 0.16; 95% confidence interval, 0.08-0.35). Celecoxib administration is associated with decreased incidence and severity of heterotopic ossification after hip resurfacing performed using the direct lateral approach in male patients.
