Versatility of the Pedicled Latissimus Dorsi Myocutaneous Flap in Reconstruction of Upper Limb and Trunk Soft Tissue Defects.

The purpose of the study was to share our indications, technique, outcome, and complications associated with the pedicled latissimus dorsi myocutaneous flap (LDMF) for reconstructing various upper limb and trunk soft tissue defects. We reviewed the prospectively collected data of the patients who underwent reconstruction of upper limb/trunk soft tissue defects with pedicled LDMF between January 2016 and March 2019. By analyzing the clinical scenarios, the location of flap inset, the arc of rotation, reach of the flap, and associated complications, we put forward few significant findings from our experience. Thirty-four patients were included in the study: 13 of them underwent LDMF for coverage of upper limb defects, 12 of them for postradical mastectomy soft tissue defects, 8 for posterior trunk reconstruction, and 1 for sternal wound infection. LDMF was successfully used to cover the scapula, anterior and posterior arms, axilla, cubital fossa, mid-forearm, breast, sternum, and midline dorsal wounds. When used reversely, the flap could cover the exposed spine in the midline dorsum. Three patients (9%) had major complications (two patients had partial flap necrosis which required additional debridement and skin grafting, and one patient required an additional transpositional flap). Three patients had minor complications (managed nonoperatively). Pedicled LDMF is a straightforward and versatile option for reconstruction of the varied upper limb and trunk soft tissue defects with minimal complications. This is a level IV, therapeutic, retrospective study.
