Experiencia en el uso de colgajo de Becker para manejo de defecto de cobertura en aspecto dorso-cubital de la mano: análisis retrospectivo de 5 casos / Experience in the use of the Becker flap to manage coverage defects in the dorso-ulnar aspect of the hand: retrospective analysis of 5 cases

ABSTRACT

INTRODUCTION: Coverage defects of the hand and wrist are usually secondary to high-energy trauma, these must be resolved quickly to protect the underlying vital structures, preserve hand functions and allow early rehabilitation. The dorsal ulnar artery flap (Becker flap), in addition to being a non-demanding surgical technique, has the main advantage of preserving the main vascular axes of the forearm. MATERIALS AND METHOD: Retrospective descriptive study in patients with post-traumatic coverage defect in the dorsum-ulnar aspect of the hand, who were managed with a Becker flap between January 2015 and December 2018.Was analyzed age, sex, mechanism of injury, surgical time, size of the defect, type of donor site closure, complications, and functional outcomes/pain/satisfaction/range of motion with the Mayo Modified Wrist score. RESULTS: In total there were 5 cases, all male, with an average age of 53 (31-58) years, who suffered a high-energy trauma. There were 2 complications, one partial epidermolysis and one deep infection with loss of the flap. Follow-up time was 12 weeks for all cases. The results of the Mayo Modified Wrist Score on average were 72 points. CONCLUSION: The Becker flap is a reproducible, rapid dissection, non-demanding, and one-stage technique. The early use of this flap allows the preservation of vital structures, decreases morbidity, allowing early rehabilitation and an early return to work.
