title: Regeneration of sudomotor and sensory nerve fibres after digital replantation and microneurovascular toe-to-hand transfer.
abstract: The end-stage sudomotor and sensory recovery in patients with replanted fingers and patients after microneurovascular toe-to-hand transfer was studied using quantitative electrophysiological investigations (recovery of sensory nerve action potentials and the sympathetic skin response), the ninhydrin test and clinical testing of sensory regeneration (light touch, pain, static and dynamic two-point discrimination). 13 adult patients with 22 replanted digits (11 males, 2 females) aged 21-58 years (mean 42.2 years) and 12 adults and adolescents (8 males, 4 females) aged 13-45 years, (mean 26.8 years) following 14 microneurovascular great and/or second toe-to-hand transfers were studied. The replanted fingers were examined 2-7 years after injury and replantation. The toe-to-hand transfers were examined 2-12 years after injury and transfer. The results show better end-stage recovery of sudomotor and sensory function following finger replantation when compared to microneurovascular toe-to-hand transfer.
