OBJECTIVES: To determine whether muscle-to-adipose ratio (MAR) along the course of a Kocher-Langenbeck incision is more accurate at predicting postoperative wound complications after acetabular fixation than waist-to-hip ratio or body mass index (BMI). DESIGN: Retrospective case series. SETTING: Level 1 Trauma Center. PATIENT SELECTION CRITERIA: Patients who sustained an acetabular fracture and had fixation through a Kocher-Langenbeck approach from January 1 st , 2008 to December 31 st , 2018. For inclusion, patients had to have a pre-operative and a post-operative CT of the pelvis and a minimum follow up of 12 months. Patients were excluded if an antibiotic other than cefazolin was administered for prophylaxis, if they had a femur fracture treated with an antegrade intramedullary nail, if there was any associated pelvic ring injury requiring surgical treatment of any type, if there were any abdominal or pelvic procedures completed by another surgical service, if the patient underwent pelvic embolization of a vessel, if there was presence of a genitourinary injury or Morel-Lavallée lesion, or if there was a subsequent surgical procedure unrelated to the primary endpoint (e.g., revision fixation). OUTCOME MEASURES AND COMPARISONS: Presence of a surgical site infection or a wound healing complication. BMI, WHR and MAR were evaluated and compared for their ability to predict a surgical site infection or a wound healing complication. RESULTS: One-hundred ninety-three patients wer...
