An anatomic examination of the suprascapular flap.

To investigate the potential utility of a suprascapular flap, the authors examined dissected cadavers to identify the ramification of the suprascapular artery, and directly injected 2.5% patent blue dye to observe the distribution of its cutaneous perforators. Results indicate that a suprascapular flap is not practicable. The branching pattern of the suprascapular artery from the subclavian artery varies widely, making dissection of the vessels highly problematic. Moreover, no constant presence of cutaneous perforators from the artery could be identified in either the suprascapular fossa or the shoulder.
