When anatomical dissection of the LD muscle is performed, an incision is made parallel to the spinous processes from T2 to L4. Two transverse incisions are made: one from T2 to the axillary fold, the other from L4 to the lateral iliac crest (Fig 1). After a layer consisting of skin with the subcutaneous layer of fat is freed and reflected laterally, the superficial surface of the LD is seen, covered with a tough layer of fibro-fatty fascia, obscuring significant anatomical details. The lower origin of the trapezius is freed and reflected cephalad. An incision is made near the inferior angle of the scapula along the superior border of the LD toward the vertebral column and laterally toward the axilla. The thoracodorsal aponeurosis is incised and carefully reflected to avoid the inclusion of the adherent underlying serratus poste-
