The reverse turnover latissimus dorsi flap for closure of midline lumbar defects

The surgical treatment of wounds located in the median lumbar area is difficult. When occurring after neurosurgical procedures, they may display a high level. of complexity because of dural exposure, deep irregular three-dimensional contours, and bacterial. contamination of the wound. The difficulty of reconstruction in that region of the body is made greater by the few possible regional flaps available in the vicinity. In order to obtain well-vascularised tissue, with good resistance to bacterial contamination and easy to shape into such defects, the reverse turnover latissimus dorsi flap is a useful surgical option. Between 1998 and 2003, four patients presented with complex lumbar wounds in our department. Three patients were adults (mean age: 63 years) and one patient was 1 year old. In all cases, reconstruction was needed in the lumbar area after surgery on the spine. All wounds presented with bacterial. contamination. In three cases, dural exposure was present, white in the fourth case, a small remnant of the posterior vertebral bony lamina was still present after debridement. In all. four cases, the reconstruction was successfully achieved by turning over the latissimus dorsi to reach the lumbar midline defect. In one case, the adult paraplegic patient, only the inferior part of the muscle was harvested, to preserve an innervated upper part of the muscle for upper limb function. In the four cases, long term results were excellent (the mean follow up was 3.5 years), with no residual infection. (C) 2007 British Association of Plastic, Reconstructive and Aesthetic Surgeons.
