METHOD FOR THUMB RECONSTRUCTION IN TOTAL DEFECTS OF RADIAL BORDER OF HAND

摘要

FIELD: medicine.;SUBSTANCE: at the first stage, restoring a ball of the thumb and forming a soft-tissue finger frame are ensured by a repair of the radial border of hand with using a double skin-fat flap. After the flap survives, a fragment of the second instep bone on microanastomosis with a small skin-fat flap is grafted in a position of the first metacarpal bone. A transverse osteotomy of the restored first metacarpal bone is performed in the middle one-third. A pin is brought through its distal fragment; a bearing plate for formed on a proximal end of the pin. A distal end of the pin is brought out through the soft-tissue thumb frame and fastened to a screw rod of an external fixation apparatus applied to a forearm. That is followed by a distraction of a distal fragment; thereafter a nonvascular cortical-spongious bone autograft is placed between the bone fragments of the metacarpal bone with preserving the formed distraction regenerate, and an osteosynthesis of the bone fragments is performed.;EFFECT: method enables forming the thumb of the adequate length and provides the bone frame stability.;4 dwg, 1 ex
