METHOD OF REPLACING CLAVILA DEFECT Russian patent published in 2023 - IPC A61B17/60 A61B17/72 

FIELD: medicine; traumatology; orthopedics.

SUBSTANCE: invention can be used to replace a clavicle defect. The method includes exposure of clavicle fragments, excision of fibrous tissue filling the diastasis between clavicle fragments, and installation of a graft. Sclerotic fragments of the clavicle are skeletonized and resected to the blood supply to the bone tissue. The patency of the bone marrow canal is assessed. The medullary canal is drilled out with a 1.8 mm diameter needle along the proximal and distal fragments. The clavicle axis is restored. The wire is installed intramedullary into the fragments. The size of the defect is measured. The wound in the clavicle area is packed while working with the donor site. From a linear skin incision along the lateral surface of the leg, a layer-by-layer approach to the fibula is formed, skeletonization of the fibula is performed with retractors inserted behind the medial surface. Using a vibrating saw, a free non-vascularized fragment is taken to the full diameter of the fibula of the required length to ensure replacement of the defect. The fragment is used as a graft. The wound on the lower leg is sutured in layers, the tampons are removed from the wound in the clavicle area, the intramedullary wire is removed from the defect area, plastic surgery of the defect is performed with the graft immersed in the defect area and the clavicle and graft fragments are fixed with the intramedullary wire. The wound in the collarbone area is sutured. Three cantilever wires are inserted into the clavicle fragments and their free ends are fixed with an external fixation device. Compression is performed until the graft and clavicle fragments come together; in the postoperative period, maintenance compression of 1 mm is performed once every two weeks.

EFFECT: method ensures replacement of the clavicle body defect with minimal skeletonization of clavicle fragments and the possibility of subsequent dosed axial compression on the graft without the use of optical magnification devices and microsurgical equipment for collecting a full graft from the fibula due to the features of graft collection and the features of replacing the clavicle defect.
