Abstract

The invention discloses a fixing and supporting piece for tibia osteotomy, the fixing and supporting piece for tibia osteotomy can fill a gap appearing at a tibia cut-off position, specifically, a fixing steel plate is fixed to a tibia firstly, then a first supporting block is embedded into the gap appearing at the tibia cut-off position, and a second supporting block is embedded into the gap appearing at the tibia cut-off position; then, a second wedge-shaped block can be driven to slide by rotating a first rotating rod, then a first wedge-shaped block is pushed to ascend and descend, an ejector rod is pushed, then a second supporting plate is driven to move in the direction away from a first supporting block, and therefore the purpose of expanding the thickness of the first supporting block is achieved, that is, the first supporting block can support a larger gap; therefore, the osteotomy support is suitable for osteotomy gaps of different sizes and plays a better role in supporting the tibia. By filling the gap at the tibia cut-off position, the overall strength of the tibia is guaranteed, and complications such as fracture of the osteotomy hinge, postoperative fixing angle loss and non-healing at the cut-off position are avoided.

Description

technical field [0001] The invention relates to the technical field of orthopedic medicine, in particular to a fixed support for tibial osteotomy. Background technique [0002] Knee osteoarthritis is a degenerative joint disease that starts from the wear and tear of knee cartilage. The main clinical manifestations include joint pain, deformity, stiffness, and dysfunction. It has a high incidence and great social impact. The natural history of knee osteoarthritis is anteromedial osteoarthritis, which can affect all compartments of the knee joint in the middle and late stages. Patients are often accompanied by varus of the lower limb alignment, and the varus gradually increases with the wear of the knee joint, which seriously affects the quality of life of the patient. When it develops to the end-stage, artificial joint replacement has to be performed. [0003] At present, the surgical treatment of anteromedial knee osteoarthritis in the early and middle stages mostly adopts ...
