[Burned palm reconstruction. Current concepts regarding grafting techniques, sensibility and hand function]

The purpose of this study was to evaluate the results of conservative and operative treatment for burn injuries in the palmar region of the hand. METHODS AND CLINICAL MATERIAL: One hundred ten patients from the severe burn center in Ludwigshafen, Germany were evaluated a mean of 28 months postoperatively. Sixty-one had been treated with split-thickness skin grafts (43 sheet and 18 mesh grafts). In addition to subjective evaluation (including pain assessment and aesthetic outcome rating by visual analog scale), objective outcome analysis included clinical tests, measurement of active range of motion and grip strength, and sensibility testing with the two-point discrimination and Semmes-Weinstein monofilament tests.

Of the patients, 90% were satisfied with the results, showing excellent pain relief with an average score under 13 on the visual analog scale. Aesthetic outcome was rated good with sheet grafts; in appearance, mesh grafts tended to be rated average or insufficient. Functional outcome tests demonstrated a significant correlation between depth of injury and range of motion. Grip strength analysis revealed superior results with sheet grafts. Sensibility in the injured areas was lower than on the contralateral hands. The Semmes-Weinstein test average was 3.4 degrees at the burned area vs 3.0 degrees in healthy hands, underscoring lower sensibility after burns.

Surgical treatment of burned palms leads to good subjective and objective results, if specialized burn units are involved. Overall sheet transplantation seems to be the better choice for surgical reconstruction of the palmar burned hand.
