Abstract

Background: Bi-lobed second dorsal metacarpal artery (SDMA) flap is a viable option for the reconstruction over electrical burns of hand in the pediatric patients. The purpose of this study is to evaluate of the success rate and donor site range of motion after SDMA flap.
Methods: A prospective observational cohort study was undertaken in all patients who underwent reconstruction with SDMA flap at institution from March 2016 to March 2018. Data was collected regarding flap success rate and active motion arcs of metacarpophalangeal joint (MCPJ) and proximal interphalangeal joints (PIPJ) of donor area.
Results: Among 32 patients, survival rate of flap is 96.87 percent (n=31) with only partial loss of 3.12 percent (n=1). At mean follow up of 12 months, donor finger movements at MCPJ and PIPJ were almost similar to that on opposite side.
Conclusion: Second dorsal metacarpal artery flap is useful and reliable flap in complex reconstruction of burn hands in pediatric group in terms of survival and range of motion.
