Pediatric obesity is associated with short-term risks after pelvic osteotomy.

The risk factors for increased perioperative morbidity following pediatric pelvic osteotomies are poorly understood. The purpose of this study was to characterize differences in adverse events, operative time, length of stay, and readmission following pelvic osteotomy for obese and nonobese patients. A retrospective cohort study was carried out using the National Surgical Quality Improvement Program Pediatric database to identify patients that underwent pelvic osteotomy with or without femoral osteotomy. Obesity was found to be an independent risk factor for blood transfusion (relative risk: 1.4, P=0.007) and readmission (relative risk: 2.3, P=0.032) within 30 days. These data can facilitate patient counseling and informed decision-making when planning for surgical correction of hip dysplasia.
