Abstract

Objectives: To develop a radiographic fracture scoring system for lateral compression type 1 (LC-1) pelvic fractures based on OTA/AO survey data and to preliminarily evaluate this system within an LC-1 pelvis fracture cohort. Design: Survey study with validation patient cohort. Setting: Two Level 1 academic trauma centers. Patients/Participants: Attendings (n=111) at the 2013 OTA/AO national meeting reviewed imaging from 27 LC-1 fractures and indicated surgical recommendations (“yes/no”). A separate LC-1 fracture cohort (33 patients) was used to evaluate the scoring system. Intervention: The LC-1 scoring system (range: 5–14) based on radiographic morphology of sacral, superior ramus (SR), and inferior ramus (IR) fracture components. Main Outcome Measurement: Numeric scores were compared against (1) OTA/AO attendees' operative recommendations and (2) LC-1 cohort treatment and outcomes. Results: Operative tendency of OTA/AO survey respondents—defined as the percent of “yes” responses to recommend surgical stabilization—was highly correlated with radiographic findings: sacral displacement {odds ratio (OR) = 18.9 [95% confidence interval (CI): 11.7–30.6]}; sacral column 2–3 versus 1 [OR = 5.7 (95% CI: 3.9–8.3)]; Denis classification [OR = 10 (95% CI: 6.7–14.9); IR displacement OR = 3.4 (95% CI: 2.3–4.8)]; and SR fracture [OR = 1.9 (95% CI: 1.3–2.8)]. … See full text for complete abstract.
