[Heterotopic replantation of fingers after traumatic amputation].
Available are the results of the treatment of 93 patients with multiple traumatic amputations of the fingers, in whom the heterotopic digital replantation was carried out. A total of 367 fingers were amputated, 187 of them have been replanted, which made up 51% of replantability. 148 fingers (79.1%) were replanted heterotopically and 39 (20.9%)--orthotopically. The viability was restored in 167 fingers, which made up 89.3%. Of 148 fingers, which have been replanted heterotopically, 88.6% have survived, and of 39 fingers, being replanted orthotopically, 92.4% survived. The analysis of functional results of the digital replantations in hand comprised the study of the hand biomechanics, blood supply and innervation. A total of 31 patients was followed up and examined in long term period from 8 months to 6 years after replantation. The biomechanics of the hand was assessed according to its capacities for seize and pinch as well as to the extent of movements in the joints of the restoration of digital innervation was assessed by the study of temperature and discrimination sensitivity. For evaluation of blood supply the US dopplerography and scintigraphy were used. The authors came to the conclusion that there was no substantial difference in the function of operated fingers both in orthotopic and heterotopic replantations. Taking into account that heterotopic replantation of the fingers resulted in more active digital function, it is safe to speak about more pronounced increase in the function of the hand in cases of heterotopic replantations of fingers in their multiple traumatic amputation.
