This study identified factors that negatively influence functional outcomes after operative management of acetabular fractures, including smoking, obesity, comorbid diabetes, post-traumatic arthrosis, and heterotopic ossification. Smoking had the strongest association with worse outcomes, followed by the severity of heterotopic ossification.
Introduction: Recent large series of patient-reported outcomes after acetabulum fracture are limited, and potentially modifiable risk factors may be unidentified. The goal of this study was to describe patient and injury factors which negatively influence functional outcomes following operative management of acetabular fractures. Methods: 699 patients with acetabular fractures were treated with open reduction and internal fixation (ORIF). Musculoskeletal Function Assessment (MFA) questionnaire was completed after a minimum 12 months post-injury by 283 adults. MFA scores range from 1 to 100 and higher scores represent greater dysfunction. Factors were assessed for potential association with MFA scores, and univariate and multiple linear regression analyses were performed. Results: Survey respondents were more severely injured than non-respondents, with more chest injury (38% vs 22%, p < 0.001) and higher Injury Severity Score (19.3 vs 16.8, p = 0.003). Patients were 69% male with mean age 44.0 years. Approximately one-third were smokers (31%), while 14% had comorbid dia-betes mellitus type II. The majority of injuries occurred during a motor vehicle collision (65%); low-energy mechanisms were rare (4.2%). The most common fracture pattern was isolated posterior wall (23%), fol-lowed by transverse/posterior wall (21%). Heterotopic ossification (HO) was noted in 22%: Brooker 1: 29.5%, 2: 23.0%, 3: 32.8%, and 4: 14.8%. Tobacco use (beta = 18.4, p < 0.001), obesity (beta = 0.39, p = 0.009), diabetes (beta = 8.2, p = 0.029), post-traumatic arthrosis (PTA) (beta = 5.94 p = 0.035), and increasing HO sever-ity (beta = 8.93, p < 0.001) were independently associated with worse MFA scores. Tobacco use had the strongest association, followed by the severity of HO. Conclusion: In a large series of patient-reported functional outcomes following fixation of acetabular fractures, tobacco use, obesity, comorbid diabetes, PTA, and HO were associated with worse MFA scores. Further study to mitigate HO should be considered. (C) 2020 Elsevier Ltd. All rights reserved.
