The proposal relates to medicine, namely to traumatology and orthopedics, and can be used for fixing bone fragments of long bones to support the external fixator in the presence of the medullary cavity of a foreign body (the intramedullary rod, the leg prosthesis, cement spacer antibiotic) or channel osteomyelitis .Kit for fixing ekstrakortikalnoy Ortho-SUV (EFC Ortho-WOS) consists of a modified latch ekstrakortikalnogo Ortho-SUV (EF Ortho-IMS - M) and two tools to install it. Ortho-EF WOS - M consists of two main parts: the part submerged, with which contact is with the bone fastener, and the outside, which is attached to a support apparatus for external fixation. Immersion of the device consists of a foot in a hook 1 having four edges. At the end of the foot over the inner surface has a pointed tooth 2. At the end of the third rib has a toothed portion on an inner surface on which is located a number of small teeth 3. Its base is connected to the foot threaded rod - 4, wherein the two facing each other are made of longitudinal 5. a threaded rod recess is provided with a sleeve 6 and the nut 7. The sleeve 6 has two longitudinal opposite each other rectangular protrusion 8 corresponding to the grooves 5 on the rod. Also, the sleeve has at one end a sample 9 and an angular planar thrust pad with two pointed prongs at the ends 10, and the other two holes 11 arranged opposite each other in the plane of the foot. The tool for installation №1 consists of hexagonal handle 12, connected by a curved rod 13 with a hollow sleeve 14 having two longitudinal rectangular protrusion 15 and corner 16 samples at one end. №2 installation tool is designed as a hexagonal handle 17, connected by a curved rod 18 with the housing 19, one part of which is formed as a C-shaped bracket 20, the second - in the form of a T-shaped abutment 21, the C-arm is a threaded opening 22 and bolt - 23 on the one hand, and the finger 24 - the opposite.A positive result is the ability to offer a stable, lo
