A Challenging Case of Using Manta Ray Skin Flaps in a Severe Post-Traumatic First Web Space Contracture.

BACKGROUND First web space contracture affects thumb function and grasping capacity. This pathology alters normal anatomy and results in decreased ability to use the hand. Appropriate release and resurfacing are needed to restore normal hand function. Principles of successful treatment also include providing healthy compliant skin for a tension-free closure and a smooth healing period. The Manta Ray skin flaps are utilized in children, allowing the position of as much local skin as possible with minimal dorsal scarring. The technique has potential use in adults who have less skin plasticity and pliability. CASE REPORT We present the case of a 36-year-old patient with a severe first web space contracture of the dominant hand. Primary concerns of the patient were loss of hand mobility, limited grasping ability, and an inability to "give a proper handshake". Medical history suggests a gunshot wound in early childhood treated operatively by a mild web release after the point of trauma, with insufficient outcomes. We proceeded with the Manta Ray flap technique using 3 dorsally-based flaps and 4 palmar-based flaps, with excellent results. CONCLUSIONS Although the Manta Ray flap procedure was developed for moderate web space contractures in children, it combines advantages of several flap techniques. It ensures sufficient web space lengthening and may be applicable in older patients if enough healthy unscarred skin is available. These unique properties and potential led us to use the method for this challenging case.
