Obesity Increases Early Complications After High-Energy Pelvic and Acetabular Fractures.
Elevated body mass index has been identified as a potential risk factor for complications in operatively treated pelvic trauma. Although obesity is an independent risk factor for morbidity and mortality following high-energy blunt force trauma, there is little information on the immediate complications following isolated pelvic and acetabular fractures in obese patients with trauma. The authors hypothesized that obesity (body mass index ≥30 kg/m(2)) is a risk factor for complications in both operative and nonoperative pelvic and acetabular fractures. The authors conducted a 5-year retrospective data collection of all patients with isolated pelvic and acetabular fractures presenting to a Level I trauma center, excluding pediatric (age <18 years) patients, those with ballistic injuries, and those with concomitant long bone fractures or an Abbreviated Injury Scale score of greater than 2 in any other body region. Complications during the immediate hospitalization period were identified by the institution's Trauma Registry of the American College of Surgeons database, including wound infection, dehiscence, deep venous thrombosis, pulmonary embolus, pneumonia, and development of decubitus ulcers. Mean body mass index was 27.4 ± 6.8 kg/m(2), with 68 (27.0%) obese patients. Mean body mass index of patients with complications was significantly higher (31.9 ± 9.5 vs 27.0 ± 6.5 kg/m(2); P=.001). Logistic regression showed that obesity was a significant risk factor for complications (odds ratio, 2.87; 95% confidence interval, 1.02-8.04), after adjusting for age (odds ratio, 1.03; 95% confidence interval, 1.01-1.06) and Injury Severity Score (odds ratio, 1.20; 95% confidence interval, 1.10-1.32). Obesity is associated with increasing complications following operative fixation of pelvic and acetabular fractures. However, it is important to recognize that even nonoperative management of pelvic and acetabular fractures in obese patients can have early complications. This study showed a significant obesity-related risk of complications after trauma in both operative and nonoperative pelvic injuries.
