Cubitus varus orthotics for children

Abstract

The invention provides a cubitus varus orthotics for children. The cubitus varus orthotics comprises upper arm support frames, which are symmetrically arranged and are positioned at the inner side and the outer side of an upper arm, an inner side forearm molding block and an outer side forearm molding block, wherein the upper arm support frames at the inner side and the outer side are respectively connected to the inner side forearm molding block and the outer side forearm molding block through hinge mechanisms, forcing screws, which are vertically connected, are respectively arranged on the inner lateral surfaces of the hinge mechanisms at the two sides, the screw at the outer side of an elbow is 2 cm from the axis of the corresponding hinge mechanism, and the screw at the inner side of the elbow is positioned at the axis of the corresponding hinge mechanism. The purpose of the invention is to achieve the double effect of fixing a fracture end and preventing cubitus varus through causing a patient child to wear the cubitus varus orthotics after restoration of condyle of humerus. After clinical trials, the cubitus varus orthotics has the advantages of high intensity, light weight, easiness in wearing, firm fixation, good permeability and convenience for clinical observation and adjustment, and the dual purposes of firmly fixing the fracture end and preventing the cubitus varus can be realized.

Description

technical field [0001] The invention relates to a children's cubitus varus orthosis, which belongs to the technical field of medical devices. Background technique [0002] Supracondylar fracture of the humerus refers to fractures 2 to 3 cm above the medial and medial condyles of the distal humerus. It is the most common in children and accounts for the highest incidence of elbow fractures. There are various treatment methods for supracondylar fractures of the humerus, mainly including closed reduction, open reduction, and traction. Wait. Elbow varus is one of the most common complications of humeral supracondylar fractures, with an incidence rate of about 3.3% to 79.2%. It has greatly affected the function and appearance of the children's elbow. Preventing elbow varus is a medical problem that orthopedic surgeons need to solve. [0003] At present, most scholars tend to the "one-off theory" that there is an ulnar deviation or an ulnar inclination angle after the distal fra...

Problems solved by technology

The orthosis disclosed in this patent is an orthosis that connects the upper arm and the forearm through an adjustment rod. In clinical trials, the orthosis has a poor effect on correcting cubitus valgus in children, and its structure is also stable and reasonable.
