An absorbable spacer for high tibial osteotomy

Abstract

The invention provides absorbable pads for high tibial osteotomy and belongs to the technical field of orthopedic medical devices. The absorbable pads are used for high tibial osteotomy and used for treating knee osteoarthritis. A technical scheme of the absorbable pads is characterized in that the pads are boards, and ejection bars are straight bars; the thickness of each pad is gradually increased from the front end to the rear end, a wedge shape is formed, and the rear part of the pad is wider than the front part of the pad; bulging barbs are arranged on the upper board surface and the lower board surface of each pad, and front ends of the barbs are sharp; an ejection bar hole is formed in the rear end surface of each pad and penetrates through a pad body slantwise from the rear end surface of the pad to the upper front part, a front end opening of the ejection bar hole is located in the upper plate surface of the pad, the ejection bar penetrate through the ejection bar hole, and the front end of the ejection bar is opposite to a tibia platform. The absorbable pads are initiative for proximal fibular osteotomy combined high tibial osteotomy, effectively solves the problem that too large varus deformity cannot be corrected with fibular osteotomy, can perform synchronization therapy on associated compression fractures or collapse of a tibial plateau and greatly simplifies the surgical process.

Description

technical field [0001] The invention relates to a gasket used for treating knee osteoarthritis by high tibial osteotomy, and belongs to the technical field of orthopedic medical devices. Background technique [0002] Knee osteoarthritis is a common senile degenerative disease based on uneven subsidence of the knee joint caused by osteoporosis. The main clinical manifestations include joint pain, deformity, stiffness, and dysfunction. According to the affected parts and scope of knee osteoarthritis, it can be divided into medial compartment type, lateral compartment type, patellofemoral type and total joint type. Among them, medial compartment type accounts for the majority of primary osteoarthritis. 74%. Patients with medial compartment knee osteoarthritis are often accompanied by changes in the alignment of the lower limbs and varus deformity, which seriously affect the quality of life. [0003] The commonly used clinical method is to use high tibial osteotomy to treat kn...

AI Technical Summary

Problems solved by technology

However, patients with excessive varus angle can relieve pain after fibular osteotomy, but cannot correct varus deformity. It has become an urgent problem to be solved in clinical treatment

[0005] At the same time, the late stage of knee osteoarthritis often manifests as medial or lateral tibial platform collapse. How to treat medial compartment knee osteoarthritis at the same time with proximal fibular osteotomy combined with high tibial osteotomy? The compression fracture or collapse of the tibial plateau in this part of patients has not been reported to be supported and reset, which is also a problem that has not been effectively solved in clinical treatment so far.
