We studied 178 patients undergoing total hip arthroplasty (66 men and 112 women) retrospectively, with regard to the incidence and severity of heterotopic ossification and the significance of postoperative prophylaxis with non-steroid anti-inflammatory drugs. The overall incidence of heterotopic ossification was 32% 1 year after surgery. The factors increasing the incidence were male gender, previous arthroplasty of the contralateral hip joint, previous surgery on the hip, absence of preoperative treatment with non-steroidal anti-inflammatory drugs and an operating time of more than 100 min. The incidence of heterotopic ossification was lower in the patients of O blood group.
我们回顾性研究了178例行全髋关节置换术的患者(66例男性和112例女性),探讨异位骨化的发生率和严重程度以及术后使用非甾体类抗炎药预防的意义。术后1年异位骨化的总体发生率为32%。增加发生率的因素包括男性、对侧髋关节既往行关节置换术、既往髋关节手术史、术前未使用非甾体类抗炎药治疗以及手术时间超过100分钟。O血型患者异位骨化的发生率较低。
