SummaryThree retrospective cohort studies of patients with acetabular fractures examined the impact of morbid obesity on patient complications after operative fracture fixation.The morbidly obese patient appears to have an elevated risk of more perioperative blood loss and of wound infection. While a higher rate of nerve palsy and pulmonary embolism was reported among morbidly obese patients compared with those in other weight categories in all studies, statistical significance was not achieved.One study reported increased risk of deep vein thrombosis (DVT) for obese patients compared with normal-weight patients.3项回顾性队列研究试图阐明髋臼骨折内固定术后，患者合并病态肥胖对术后并发症的影响。研究显示病态肥胖的患者术中失血量和伤口感染率更高。虽然与其他体质量的患者相比，病态肥胖的患者出现神经麻痹和肺栓塞的几率更高，但差异无统计学意义。1项研究报道，与正常体质量患者相比，肥胖患者深静脉血栓形成(DVT)的发生率更高。
