Abstract

Abstract : Background: Although external circular frame (ECF) has been widely used for the correction of knee and ankle deformities, few studies reported the use of ECF for the treatment of severe postburn elbow contracture and stiffness (SPECS). The purpose of this retrospective study was to investigate the effectiveness and safety of the distraction using ECF in treating SPECS. Methods: After institutional review board approval, we implemented a retrospective single-center case series study composed of consecutive patients treated for SPECS at Chinese PLA General Hospital between January 2010 and January 2018. After scar release and skin grafting, distraction with ECF was performed for 4 to 6 weeks, and the frame was retained for 2 more weeks before removal. Four weeks of splinting and at least 1 year of rehabilitation were recommended. Patient demographics, active and passive range of motion (ROM) of the elbow at different time points (preoperative, postdistraction, and final follow-up), and complications were collected from the electronic medical record. The primary outcome was the long-term improvement of the ROM. Other outcomes included complications and recurrence. Results: The ECF was used to treat SPECS in 6 patients (3 males and 3 females, average age of 11.7 ± 2.6 years). Scar release and distraction with ECF significantly increased both active (from 3° preoperative to 38.7° postdistraction) and passive (from 3.5° preoperative to 48.3° postdistraction) ROM over an average distraction duration of 5.2 weeks. The long-term improvement of active and passive ROM was 38° ± 13.4° and 46° ± 14.7°, respectively, over a median follow-up of 4.1 years. Pin-tract infection occurred in 2 patients and were treated with local wound care and oral antibiotics. A tendon readhesion developed in 1 of the 6 patients because of noncompliance with splinting and physiotherapy, and was treated with revision surgery. Conclusions: The 3C strategy (i.e., contracture release, coverage of the defect with skin grafting, and correction of articular angle with gradual distraction using the ECF) is able to increase the ROM with minor complications. We recommend distraction with ECF as part of the treatment arsenal, particularly for severe contractures in which 1-stage correction is unfeasible because of considerable soft tissue shortening.
