Simultaneous internal fixation and latissimus dorsi pedicle flap coverage: A reliable regimen for open fractures with accompanying sizable soft tissue loss of the upper extremities

Abstract

BackgroundThe optimal treatment protocol for open fractures with accompanying sizable soft tissue defect of the upper extremities has not been specifically delineated. The authors described the concurrent use of internal fixation and latissimus dorsi (LD) pedicle flap coverage in managing such complex fractures. MethodsTwenty patients with open fractures accompanied by large soft tissue defect of the upper extremities (8 clavicle fractures and 12 humeral fractures) were treated by fix & LD pedicle flap. The dimension of the defect, time to fix & flap, post-operative complications, time to union and clinical measurements were recorded. ResultsThe mean size of the defect was 132.45 cm2 (range 6–12 x 2–20 cm2). The average time to fix & flap was 9.9 days (range 7–14). Fractures union was achieved in all patients with an average duration of 18.5 weeks (range 14–28). Regarding post-operative complications, distal flap necrosis occurred in 3 patients, retained seroma in 3 and heterotopic ossification in 1. By the Mayo Elbow Performance (MEP) score, 3 cases were considered to be excellent, 6 were good, 7 were fair and 4 were poor. By the University of California–Los Angeles (UCLA) shoulder score, 2 cases were considered to be excellent, 7 were good, 7 were fair and 4 were poor. The average Disabilities of Arm, Shoulder and Hand (DASH) score was 31.29 (range 12.5–58.3). ConclusionFix & LD pedicle flap is a reliable regimen for open fractures with sizable soft tissue defect of the clavicle and humerus.
