METHOD FOR HAND REPAIR IN AMPUTATION STUMPS OF ALL FINGERS

摘要

FIELD: medicine.SUBSTANCE: stem is formed of a non-free tubular inguinal flap. The stem is anchored to the thumb stump and a donor stump to form a loop. A gradual axial distraction of a distal fragment of the metacarpal bone together with pedicles thereby burying into a stem pedicle is performed 2 months later. A longitudinal osteotomy of the distal fragment is performed with forming two segments: dorsal and palmar, with preserving a constraint of the bone fragments with the dorsal and palmar pedicles, and the junction of the formed distraction regenerate with the dorsal segment. The dorsal and palmar segments are mobilised on the pedicles of the same name. The stem loop is divided into lateral and medial portions in the form of an adipocutaneous flap keeping the stump constraint intact. The palmar segment is transferred onto the thumb stump on the palmar pedicle; the dorsal segment is mobilised on the dorsal pedicle and transferred onto the stump of the third metacarpal bone. Tissue defects of the thumb and third fingers are replaced by flaps of the medial and lateral halves of the stem.EFFECT: method makes it possible to form the thumb and third finger and provide the gripping function of the hand.1 ex, 8 dwg
