Minimally invasive burn reconstruction with subcutaneous scar contracture release

Abstract

Background: Scar contracture bands after burns are frequent problems that cause discomfort and physical limitation. This study investigates the efficacy of a minimally invasive contracture band release technique (MICBR) inspired by closed platysmotomy.

Methods: Patients with burn scars treated with MICBR in our center were included retrospectively. Our routine scar and contracture treatments (non-invasive and invasive) were utilized prior to undergoing MICBR. Range of motion (ROM) and Vancouver Scar Scale was measured before and after the procedure when feasible.

Results: Forty-five patients were included, with 97 total contracture sites treated all over the body. An average of 1.6 sites were treated per patient, with a maximum of six. Patients age was 6-68 years; total burn surface area ranged from 0.5% to 85%. 24% were performed under local anesthesia. 84% were in originally skin grafted areas. We found significant improvements in ROM and VSS. 84% of patients surveyed were "satisfied" or "very satisfied". 95% reported improved mobility. No significant adverse events occurred.

Conclusion: This MICBR technique is a versatile, safe, and well-tolerated adjunct procedure that can help patients regain mobility after a burn injury.
