Morphometric examination of the free scapular flap.

In this study we investigated the clinicoanatomic basis of the scapular flap by morphometric examinations of 42 cadavers. Our findings were as follows: With common-trunk type scapular vessels, the maximal lengths of arteries and veins that could be used for a flap pedicle were 93 and 91 mm. With direct-type scapular vessels, the maximal lengths were 95 and 71 mm. In common-trunk type vessels, the mean internal diameter 2 mm distal from the confluence of the scapular vessel was 2.8 mm for arteries and 3.3 mm for veins. In the direct-type vessels, the mean internal diameter 2 mm distal from the confluence of the circumflex scapular vessel was 1.8 mm for arteries and 3.3 mm for veins. The maximal superoinferior dimension of the scapular graft was 28 mm. The maximal lateral dimension of the scapular graft was 12 mm.
