An external fixation brace for correcting the valgus deformity of the knee joint

Abstract

The invention discloses an external fixation brace for correcting varus and valgus malformation of knee joints. The external fixation brace comprises an upper fixing plate used for fixing the lower end of a thigh, and a lower fixing plate used for fixing a crus, wherein a connecting plate is connected with the side, close to the lower fixing plate, of the upper fixing plate; fixing rings are arranged at the two ends of the upper fixing plate and the two ends of the connecting plate, and a connecting shaft passes through the interior of each fixing ring; two columns of through holes are formed in the connecting plate in parallel, two columns of through holes are correspondingly formed in the side, close to the connecting plate, of the lower fixing plate, and screws are respectively inserted between the through holes of the connecting plate and the through holes of the lower fixing plate; binding bands are respectively and evenly arranged at the two ends of the upper fixing plate and the lower fixing plate; sticking fastener bands are respectively stuck at the ends of the binding bands. The external fixation brace provided by the invention can be automatically adjusted so as to solve the problem of arthritis caused by the varus and valgus malformation of the knee joints of an elderly patient, and can adjust the varus and valgus malformation of the knee joints of the patient at any time so as to correct the poor force line of the lower limb and further relieve the paint of the patient; furthermore, the external fixation brace is simple in structure, convenient to operate, low in cost and thorough in treatment.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an external fixation brace for correcting varus and varus deformities of knee joints. Background technique [0002] Senile osteoarthritis is due to bone and periosteum lesions, plus long-term mechanical trauma, weight bearing or inflammation, which increases the intraosseous pressure. On the one hand, the joints are progressively destroyed, and on the other hand, the bone hyperplasia and osteophyte formation on the edge of the joints , the joint cavity becomes smaller, and the intraosseous pressure further increases, causing venous return obstruction, affecting intraosseous arterial blood perfusion, causing insufficient oxygen supply, sluggish clearance of secretions, slowing metabolism, and accelerating cartilage damage. In the early stage, it often starts from the space of one side of the knee joint, and it is more common on the inner side. Over time, varus ...

Problems solved by technology

Physical therapy and functional exercises take a long time and take effect slowly, making it difficult to persist

Surgical treatment is an ultimate treatment, and the 2-year failure rate after surgical treatment is 5.8%. Once it fails, some patients will face lifelong pain, and even if it succeeds at that time, the long-term curative effect is uncertain, and the requirements for case selection are strict, and the cost is too high. Large, unacceptable to many patients

Plantar wedge pads and traction therapy are both palliative treatments, not the root cause, and the effect is not clear
