Clavicular soft tissue defects present a significant reconstructive challenge especially when the bone or neurovascular structures are exposed due to scarcity of local tissue. The supraclavicular flap is a well-established flap in reconstruction of head and neck defects. However, literature about its use in closure of clavicular soft tissue defects is limited. Additionally, the role of the contralateral supraclavicular artery flap in such reconstructions has not been well described.

This report presents a case of a 45-year-old man who sustained a right clavicular soft tissue defect following a road crash injury with the medial third of the clavicle exposed. Tissue defect coverage was achieved using a contralateral island supraclavicular artery flap. No complications relating to either the flap inset or donor site were encountered postoperatively.

This case demonstrates that the contralateral supraclavicular artery flap is an effective yet underutilized option in the closure of clavicular soft tissue defects, and deserves greater consideration in the reconstructive algorithm for such defects.
