Waist-hip ratio proxy may predict wound complications after acetabular fracture surgery

Results published in The Journal of Orthopaedic Trauma showed wound complications after operative treatment of pelvic and acetabular fractures were more likely to be predicted with a waist-hip ratio proxy compared with BMI.

Researchers analyzed BMI and waist-hip ratio proxy to predict the risk of wound complications among 161 patients who underwent operative repair of pelvis and acetabulum fractures. Researchers grouped BMI into high-risk categories of 30 kg/m² or greater and 40 kg/m² or greater, while the WHO high-risk profile for women and men was used to group waist-hip ratio proxy.

Results showed 15% of patients developed wound complications. Of these, 6.8% were deep infections; 4.3% were superficial; 0.6% were pin complications; and 3.1% were wound healing complications. Researchers found wound complications were associated with increasing BMI and waist-hip ratio proxy as continuous variables and female sex. Waist-hip ratio proxy had a greater area under the curve vs. BMI when unadjusted continuous data was applied to a receiver-operating characteristic curve, according to results.

Researchers noted an optimal predictive waist-hip ratio proxy of 1 or greater. Area under the curve was greater for waist-hip ratio proxy of 1 or greater vs. BMI of 30 kg/m² or greater, BMI of 40 kg/m² or greater and WHO waist-hip ratio proxy, according to receiver-operating characteristic curve from adjusted data. Researchers found excellent interrater reliability of a CT-generated waist-hip ratio proxy. – by Casey Tingle
