Abstract

Objective:To evaluate the efficacy of using the Orthopaedic Trauma Association (OTA/AO) classification for both bone forearm fractures in predicting compartment syndrome.Design:Retrospective cohort.Setting:Level 1 Academic Trauma Center.Patients/Participants:One hundred fifty-one patients 18 years of age and older, with both bone forearm fractures diagnosed from 2001 to 2016 were categorized based on the OTA/AO classification. Patients with both bone fractures caused by gunshot wounds were excluded.Main Outcome Measurements:The endpoint for our study was whether forearm fasciotomies were performed based on the presence of compartment syndrome.Results:Of a total of 151 both bone forearm fractures, 15% underwent fasciotomy. Six of 80 (7.5%) grouped 22-A3, 8 of 44 (18%) grouped 22-B3, and 9 of 27 (33%) grouped 22-C underwent fasciotomies for compartment syndrome (P = 0.004). The relative risks of developing compartment syndrome for group 22-B3 versus 22-A3 was 2.42 (P = 0.08), 22-C versus 22-B3 was 1.83 (P = 0.15), and 22-C versus 22-A3 was 4.44 (P = 0.002).Conclusions:There is a significant correlation between the OTA/AO classification and the need for fasciotomies, with group C fractures representing the highest risk. Clinicians can use this information to have a higher index of suspicion for compartment syndrome based on OTA/AO classification to help minimize the risk of a missed diagnosis.Level of Evidence:Prognostic Level III.
