Bilateral split latissimus dorsi V–Y flaps for closure of large thoracolumbar meningomyelocele defects

Closure of large meningomyelocele wounds and defects always requires durable and safe coverage of the dural repair. A new technical method for the reconstruction of large thoracolumbar meningomyelocele defects is described in which bilateral musculocutaneous flaps are advanced and transposed medially in a V–Y sliding manner, based on the thoracolumbar perforatiors of the latissimus dorsi. This procedure provides a reliable, well-vascularized soft tissue coverage over the neural repair with minimum donor-site morbidity. Additionally, this method is particularly appropriate to the thoracolumbar area, as it preserves the lateral adjacent regions of the defect, for later alternative and/or reconstructive options.
