Anatomical Study of the Latissimus Dorsi Muscle Flap

The latissimus dorsi is a broad muscle that originates from the inferior thoracic spinous processes, thoracolumbar fascia, iliac crest, and ribs. It inserts on aspect of intertubercular groove humerus through thin tendon. study was conducted 10 cadavers (7 male 3 female). These specimens were dissected examined to gross anatomical characteristics muscle. dimensions its surface area measured in all cadavers. branching pattern thoracodorsal vessels recorded. pedicle length caliper using Vernier calipers. On 20 sides, artery found be one terminal branches subscapular axillary region. In 19 (95 %) cases, terminated bifurcation, giving off medial lateral branch. average size elevated flap 18 cm x 36 cm. 9.5 (range: 5 cm-14 cm), diameter at origin 2.5 mm 1.5 mm-3.5 mm). vena comitans 3.3 mm. current focuses features blood supply increase success rate operations clinical practice.
