Task: Intent Identification
Input (English): To assess the association of obesity and postoperative complications after operative management of tibial shaft fractures.', 'Patients who underwent operative management of a tibial shaft fracture were identified in a national database by Current Procedural Terminology (CPT) codes for: (1) open reduction and internal fixation (ORIF) and (2) intramedullary nailing (IMN) procedures in the setting of International Classification of Diseases, Ninth Revision (ICD-9) codes for tibial shaft fracture. These groups were then divided into non-obese, obese, and morbidly obese cohorts using ICD-9 codes. Each cohort was then assessed for grouped complications within 90 days, removal of implants within 6 months, and nonunion within 9 months postoperatively. Odds ratios and 95% confidence intervals were calculated.', 'From 2005 to 2012, 14,638 patients who underwent operative management of tibial shaft fractures were identified, including 4425 (30.2%) ORIF and 10,213 (69.8%) IMN. Overall, 1091 patients (7.4%) were coded as obese and 820 (5.6%) morbidly obese. In each operative group, obesity and morbid obesity was associated with a substantial increase in the rate of major and minor medical complications, venous thromboembolism, infection, procedures for implant removal, and nonunion.
