Abstract

Background The formation and severity of heterotopic ossification (HO) may be influenced by type of surgical approach. Our hypothesis was that because of differences in soft tissue dissection, differences exist in HO formation in primary total hip arthroplasty using direct anterior (DA) vs direct lateral (DL) approach. Methods A total of 1482 consecutive patients with DL (736) or DA (746) approach and similar perioperative care protocol during 2009-2011 were retrospectively studied. No patient received prophylactic radiotherapy. Preoperative and 6-month postoperative radiographs were reviewed based on Brooker classification. Results The incidence of overall HO was higher in DL (36.1%) vs DA group (19.4%, P < .001) but high-grade HO (Brooker ≥3) was not significantly different among the groups (3.9% for DL and 3.0% for DA groups). No patient required further surgery for HO resection. Conclusion The type of approach (DA vs DL) did not seem to have a major influence on the short-term incidence of high-grade HO based on this radiographic analysis.
