Reconstruction of multiple digital defects by temporary syndactylization using a lateral arm free flap

초록

Background: Treatment of multiple soft tissue defects of the fingers is challenges to reconstruction surgeons. Depending on the locations and sizes of defects, several options are available. Objective: We introduce the use of a lateral arm free flap and syndactylization for the coverage of multiple finger soft tissue defects. Material and Methods: This retrospective study was conducted based on reviews of the medical records of 13 patients with multiple soft tissue defects of fingers (n=33) that underwent temporary syndactylization with a microvascular lateral arm flap for temporary syndactylization from January 2010 to December 2020. Surgical and functional outcomes, times of flap division, complications, and demographic data were analyzed. Results: Middle fingers were most frequently affected, followed by ring and index fingers. Mean patient age was 43.58 years. The 13 patients had suffered 10 traumas, 2 thermal burns, and 1 scar contracture. Release of temporary syndactyly was performed 3 to 9 weeks after syndactylization. All flaps survived, but partial necrosis occurred in one patient, who required a local transposition flap after syndactylization release. The mean follow-up was 15.8 months. Conclusion: Coverage of multiple finger defects by temporary syndactylization using a free lateral arm flap with subsequent division offers an alternative treatment option
