Use of the Propeller Lumbar Perforator Flap: A Series of 32 Cases.

Lumbosacral substance defect is a challenge in reconstructive surgery because few coverage solutions are available in this anatomical region. Lumbar artery perforator flaps (LAPs) have been progressively developed and make it possible to solve very complex situations. We report a multicenter study on LAP performed to treat medium and low lumbar defects of various etiologies, to highlight the versatility of this flap as well as its robustness and reproducibility. Between 2012 and 2019, 32 LAPs were performed in the Toulouse and Strasbourg University hospitals. Etiologies of the defects encountered were diverse: chronic wounds following neurosurgery, oncodermatology, burn sequelae, and ballistic injury. All LAPs were used in their pedicled form, turned as propeller, and combined or not with other flaps. We treated 31 patients with 32 LAPs. Average flap size was 14.3 cm (range 8-26) × 6.5 cm (range 5-10), and average arc of rotation was 131.3 degrees (range 70-180 degrees). Only 4 patients (12.9%) presented partial necrosis, but required no other covering procedure because secondary healing was sufficient. No coverage failure was reported. Average follow-up duration was 9.7 months (range 1-18). In the case of lumbosacral defects of various etiologies, propeller LAP is a reliable and efficient surgical procedure, offering the advantage of low donor site morbidity. The reconstructive surgeon should propose this technique to patients as a first-line option where surgery is indicated.
