FIELD: medicine, traumatology, orthopedics. SUBSTANCE: before applying autotransplant into defect area the bone should be treated. For this purpose one should dissect its atrophic end to form a longitudinal channel there. Then one should rotate the treated osseous fragment for 180є to be introduced into medullary canal of the bone. Osseous revascularized autotransplant should be placed into defect area, then one should apply axial compressing needle to fix it at one of these osseous fragments. Another osseous fragment should be supplemented with the apparatus for external fixation where one should pull intramedullarly applied needle. On stabilizing the fragments and the transplant one should perform microsurgical stage of operation by suturing arteries and veins. The method suggested improves conditions for the increment of revascularized osseous autotransplant due to developing a stable edge support between the transplant and osseous fragments. EFFECT: higher efficiency of fixation. 3 dwg
The invention relates to medicine, namely to traumatology and orthopedics, and is intended to ensure defect-pseudoarthrosis long tubular bones. When treating a defect-pseudoarthrosis long tubular bones using revascularisations bone autograft from the fibula (Belousov A.E., 1988; Golubev V.G., 1985; Holowchak BJ, 1993; Grishin, I.G. et al., 1994, 1996, 2001). There is a method of fixing a bone graft by Ilizarov (Shevtsov V.I., V.D. Makushin, Kutyrev L.M. Pseudoarthrosis, defects of the long bones of the upper limb and contracture of the elbow joint /basic technologies of treatment by Ilizarov/. - Barrow: the Urals, 2001. - S). Through the bone graft spend two pairs of crossed spokes. This can lead to severe disorders of blood supply to the bone tissue, which negatively affects reparative regeneration in the connection zone of the bone and graft, increasing the period of consolidation in 2-3 times (Onoprienko G.A., 1984, 1993). Known method combined a busy osteosynthesis (Barabash A.P., Solomin L.N. Combined stressful osteosynthesis. - Blagoveshchensk, 1992. - p.20), in which the axial compressicauda spoke conduct intramedular through the bone fragments and autograft. One of the ends of the spokes fixed plate and unsustaina, and the other end with justices who jemym force pull in an external device. The disadvantage of this method is the difficulty of creating a sustainable end stop between the bone fragments and autograft in cases of pronounced differences in the diameter of the diseased bone and graft. To eliminate telescopic implementation of the graft in the bone-marrow channel of the fragments of the recipient bone graft is necessary to position the eccentric. This reduces the contact area between the graft and the ends of the bone fragments. Axial compressicauda needle held in the bone-marrow channel is offset from the Central axis of the bone. This leads to the fact that when the tension force occurs, contributing to secondary displacement of bone fragments, which worsens the conditions for the fusion of the graft with the bone fragments. There are methods and compounds free tube allograft with resected end of the bone of the patient, which suggests the formation of different stops, in the processing of bone bits or cutters (Zatsepin ST Safe surgery for bone tumors. - M.: Medicine, 1984, pp. 102), which is unacceptable when you commit revascularizing transplant because of a possible violation of its blood supply. The technical result of the invention is to improve conditions for increment revascularizing bone autotransplant is and by creating a sustainable end stop between the graft and bone fragments. This is achieved by the fact that the autograft in the area of the defect recipient bone handled. Cut it off, atrophic end and form therein a longitudinal channel (Figure 1). Deploy processed in a similar manner, the bone fragment 180 degrees and implement it into the bone marrow canal of the bone (Figure 2). A similar operation, if necessary, performs on the opposite part. Bone revascularisations autograft is placed in a region of the bone defect, spend axial compressicauda needle and fix it with thrust pad on one of the bone fragments. On the other bone fragment impose the external fixation device and pull it intramedular conducted spoke. When this occurs compressible force at the junction fragments with the graft (Figure 3). After stabilization of the fragments and transplant perform microsurgical phase of the operation, which is the seam of arteries and veins. The method of fixation revascularizing bone autograft for the treatment of defect-pseudoarthrosis long bones with intramedullary conduction through bone fragments and autograft spokes, fixing it on one bone fragment and tension in perosseous apparatus imposed on another bone fragment, characterized in that before you placed the eat autograft in the area of bone defect treated, why cut atrophic end of the bone fragment, to form therein a longitudinal channel, unfold the bone fragment 180 degrees and implement it into the bone marrow canal of the bone, bone revascularisations autograft is placed in the region of the defect.
