Sensory Evaluation of Post Traumatic Thumb after Reconstruction with Reverse Radial Forearm Flap

Abstract

Background : Thumb is with a special role in hand function. Therefore, in addition to the significance of using thin, pliable, color-matched, and hairless cover in resurfacing the lesion in this area, recovery of sensation should also be taken into consideration.Materials and Methods : Thirteen patients with thumb degloving injuries were candidates for sensate reverse island radial forearm surgery. After transferring the flap, forearm lateral sensory nerve was sewn to the thumb digital nerve. At least for two years, these patients received regular diagnosis, and monofilament, static two point discrimination (S-2PD), and moving two point discrimination (M-2PD) tests were taken from them.Results : Monofilament test did not show normal sensation recovery, at protective sensation threshold, in the parents. The difference between monofilament test and normal thumb was statistically significant (p
