Abstract (original English)

Background: Random pattern flaps are widely used in reconstructive surgery when inadequate vascularity precludes skin graft survival or when regional pedicled flaps are unavailable due to local burn injury. Here, thin tissue from the upper arm was utilized to cover exposed cartilage over the proximal interphalangeal (PIP) joints of the contralateral hand. Methods/Technical Note: We report the uncommon application of multiple cross-arm (Colson) flaps to reconstruct dorsal skin defects over the PIP joints of the index, middle, and ring fingers following a high-voltage burn injury, in conjunction with a comprehensive literature review. Results: Three separate random-pattern flaps were harvested from the upper arm and transferred to the contralateral hand. All flaps demonstrated good perfusion, durable coverage, and a clean wound bed postoperatively, with preservation of joint mobility. Conclusions: To our knowledge, this represents one of the first reported reconstructions of multiple adjacent PIP joints using individual cross-arm flaps. This technique remains a dependable salvage option that should be considered in complex reconstructive scenarios when local or microsurgical options are not feasible.
