Management of finger deep burns: The interest of local flaps.

ABSTRACT

INTRODUCTION: The management of finger deep burns is still problematic for the surgeon. Due to the fineness and the thickness of the subcutaneous tissue, after excision there is an important risk of exposure of the underlying tissue like bone, nerve or tendons. Local flaps (random pattern flap and pedicle flap) allowed ensuring a good quality covering with a tissue with many advantages (good thickness, sensitivity). On the contrary of all other techniques, flaps can be used independently from the vascular quality of the wound bed. Despite those advantages, the literature is poor to report the experience of flap in the management of finger deep burn. MATERIAL AND METHODS: We report our experience in the use of such technique with a series of 49 flaps. The cohort consisted of 34 patients (22 men and 12 women) who were treated in our unit between 2003 and 2012. RESULTS: Of the 49 flaps made, 71,4% were homodactyl flaps. 22,5% were heterodactyl flaps and 6,1% were intermetacarpian (second space) flaps. The rate of success was 87,8%. We reviewed 16 patients out of 34 patients operated, 20 of the 49 flaps performed (40,8%). The patients were reviewed by an independent surgeon. The average follow-up at this consultation was 4,25±2,46 years. The monofilament test was positive for 17 flaps (85% of cases). For the Weber's test, we found a normal perception threshold for 11 flaps (55%), with an average test at 2,8mm (2-4mm). Normal motricity was found at the donor site in 14 of the 16 patients evaluated for 18 of the 20 revised flaps (90% of cases). In terms of cosmetic result, the average overall score obtained at the patient's own evaluation was 0.85. That obtained by the evaluator was equal to 0.55, with no significant difference (scale range from 0 best results to 5 worse results). DISCUSSION: Hand and finger burns are frequent and benefit from rapid, high-quality coverage, enabling early mobilization to combat secondary stiffness problems. The high success rate of our series, as well as the quality of the functional and cosmetic results obtained, demonstrate the reliability and the interest of the digital flaps.
