Duration of treatment of bone paste bone defects and limb shortening scar new method

Tibial skin sag and the rear adhesion, foot drop. Posterior tibial artery pulse disappeared. x ray film showed: in the lower right tibia defects 4 ~ m, ends sclerosis, medullary cavity occlusion. Fibula fracture has healed. Metaphyseal tibial epiphysis is closed. On June 13, 1988 under epidural anesthesia in the semi-ring frame with the same period, 88 off-line extension of metaphyseal nonunion of pressurized solid and postoperative l week extension of metaphyseal distraction every day lmm , a two to complete,[link widoczny dla zalogowanych], and early ambulation exercise. 1 month after the x-ray examination, has a small fracture callus growth, the metaphysis has been extended 25cnl, 8 weeks after the fracture line blurred, metaphyseal extension of 4cm,[link widoczny dla zalogowanych], the amount of barium four limbs have been so long. Knee and ankle joint function was normal. 3 removal of external fixator half, walking freely, functional recovery is good. Example 2 female,[link widoczny dla zalogowanych], 20 years old. Students. Hospital No. 228761. L0 patients in January 1987 in a car accident caused by pelvic fracture, right tibia and fibula break, and extensive soft tissue avulsion of lower extremities. Because tibial nonunion and bone exposure into our department. AGED check: the right lower limb shortening 6cm, knee and have the following widely scattered in the ulcer scar. Tibia on the l / 3 see 4 × 6cm exposed bone surface plane, and unusual activity. Knee was restricted. x-ray film showed right middle tibia fracture, the upper and lower ends of bone resorption. Defect, the medullary cavity occlusion. People at the hospital after debridement and fascia flap for repairing part of the erythema marks, 4 months after infection control, in January 1989 under epidural anesthesia in the semi ring external fixator line I tank of pressurized tibia and tibial fixation Under the metaphyseal osteotomy, limb lengthening. L week after the slow pace of a day extension of lmm, 2 weeks training with crutches out of bed. x-ray observation: pressure fixed at 1.5 months after apparent callus, 3 months healing. Extended under the metaphysis at 2 months of scheduled extended 5.5cm, pale stump visible callus. 5 months callus shadow can be seen clearly. 7 months after removal of external fixator, knee flexion compared with that before progress can be abandoned Shui walking. Discussion 1, for the tibial metaphyseal cancellous bone, the main rich blood circulation. Osteogenic ability. Osteotomy ends were a separate blood supply system. Epiphyseal side of the nutrition branch arteries from the epiphysis,[link widoczny dla zalogowanych], metaphyseal blood supply mainly from the metaphyseal intramedullary nutrient artery branches. Epiphyseal plate fusion. Two and mutually traffic. So cut off their blood supply subperiosteal metaphyseal little interference,[link widoczny dla zalogowanych], is conducive to the slow extension of metaphyseal anatomy cut bi-type ± 璺璺璺 Dong Tong Po Man! Plastic base. -2, Webevd is, most cases of bone defects (85%), nonunion bone ends there is a good blood supply. External fixation device through the park for 2.5 ~ 3mm of bone fracture of the stress generated at the same time constant, multi-plane through three interwoven steel needle fixed, effective control of all the shear fracture fragments or resistance, not to stimulate neovascularization Such is Life with organization and promotion of ossification. Besides basic research has proven that the mechanical effects of compression fracture fragments can be converted into electrical energy. Further promote bone healing. 3, treatment of leg move marks affixed to the tibia bone defects and limb shortening. Usually very difficult. First you must complete scar excision and application of plastic affixed to bone or partial microsurgical technique to repair soft tissue and bone grafting Ⅱ of the line until the line of fracture healing after limb lengthening. The treatment of complicated surgery to the line three times, and long hospital stay big pain, high medical costs, there are some cases because of organizational barriers to the free blood flow after transplantation can not achieve the desired results. Bone and extend the current general approach is to make z-shaped cut tibial shaft, up and down both ends of the needle, daily extended. Since a large incision, the backbone of extensive dissection, prone to delayed healing of bone, pathologic fracture, angular deformity, paralysis and other complications. Post more does not apply to a greater bone scar cases. An extension of the femur or iliac bone lengthening surgery although they may be extended and a complete bone graft surgery, but there are still more complications, longer range and small shortcomings. We will pressure both in vitro and can stretch needle to extend the feature set in a semi-ring frame, pressure fixation in the bone defect, nonunion of the metaphyseal simultaneously cut off the extension, this method does not need to make a small incision or incision; without bone graft; without prejudice to the growth plate at both ends of the blood circulation; extend the large range; early exercise, good recovery of joint function: to avoid dealing with complex surgical scar bone paste; a surgical scar to solve a leg bone paste, bone defects and limb was shortening and deformity of the complex cases. Is a new, simple and reliable method of treatment. .
