METHOD OF TWO-STAGE ELONGATION OF STUMPS OF THREE-PHALANX FINGERS

摘要

FIELD: medicine.;SUBSTANCE: invention relates to field of medicine, namely to traumatology and orthopedics, and can be used for reconstructive treatment of stumps of three-phalanx fingers. Essence of method lies in the following: at the first stage performed is complete transaction of extensor mechanism of finger stumps and walls of osteo-fibrous canal after transversal osteotomy of elongated phalanx. After that pins are passed intramedullarly through distal fragments of distracted stumps in distal direction. Proximal ends of pins are bent in form of hook, fixing in cortical part of distal fragments of fingers, transversal pins are passed through 2-3 and 4-5 metacarpal bones, as well as through radial and ulnar bones in distal third of forearm. After that mounted is external fixation device (AFD), consisting of two rings, connected by three bars, transversal bar, fixed to distal ring of the device by means of two bars and a number of pin-holders, corresponding to the number of elongated stumps. Distraction is carried out to required value of diastasis between fragments. At the second stage EFD is removed and interpositional bone autoplasty of osteal defect that formed is performed.;EFFECT: application of claimed invention allows to perform elongation of stumps of three-phalanx fingers for greater length during short terms, using convenient arrangement of EFD.;1 ex, 7 dwg
