Transverse lumbar flap for sacral bed sores

Over the last 30 months, we covered all the 21 cases of sacral pressure sores admitted to our section with the transverse lumbar flap. All the flaps survived. The rationale of the flap design, its technique, and complications are described. The advantages and the drawbacks of the flap are also described. One of the major principles of bed-sore flaps, i.e., that the flap should be as large as possible, need not be adhered to.
