摘要：
FIELD: medicine.SUBSTANCE: invention refers to medicine, namely to restoring the integrity of the injured peripheral nerve. In the tubular implant there is an additional element in form of a solid rod, around which there is a tubular implant of biocompatible nonabsorbable polyvinylidene fluoride monothreads with diameter of 0.09 mm with a knitting density along stool of 2–3 loops/cm and a knitting density along the loop row of 8–9 loops/m, is implanted at distance of 1.5–2.0 cm from the injured nerve to form a canal with a smooth inner surface of autologous connective tissue and the wound is layer-by-layer closed with polyvinylidene fluoride monofilament 5/0. In 3–4 weeks, skin and tissues are re-dissected within tubular implant. Ends of the tubular implant are cut and a glass rod is withdrawn therefrom, in the place of which a hollow channel with an internal smooth surface is formed with subsequent connection of the cut distal and proximal ends of the injured nerve to the ends of the tubular implant, sprouted autologous connective tissue, polyvinylidene fluoride monofilament 8/0 with their orientation towards each other with further layer-by-layer wound closure of polyvinylidene fluoride monofilament 5/0.EFFECT: method enables reducing a risk of postoperative complications and recurrences by creating conditions for directed growth of the proximal end of the nerve in the formed tubular canal of the implant with a smooth surface of autologous connective tissue to the distal end of the nerve and regeneration of nerve fibre with loss of length of nerve greater than 2 cm with simultaneous protection of regenerating nerves from compression and from penetration of fibrous tissue inside formed channel.2 cl, 1 tbl, 14 dwgИзобретение относится к медицине, а именно к восстановлению целостности поврежденного периферического нерва. В трубчатом имплантате располагают дополнительный элемент в виде сплошного стержня, вокруг которого размещают трубчатый имплантат из биосовместимых
