Technical Field

The utility model relates to a recovered arm protector that pulls of humerus surgery neck fracture.

Background

Humerus surgery neck is located dissects 2 ~ 3 centimetres under the neck, and pectoralis major stop is more, and here is passed through and is slightly thin to the cortex bone by cancellous bone, is the mechanical weak area, and the fracture is comparatively common, and various ages all can take place, and the old person is more, and the humerus neck of humerus surgery fracture is shifted more seriously. The western medicine treatment is divided into two categories, one is that the external fixation is realized by manual reduction, the fixation time of the method is about 4-6 weeks, joint adhesion is easily caused, and the recovery of limb functions is affected. And secondly, the incision reduction internal fixation increases the economic burden of a patient, and has operation risks, postoperative scar adhesion and influence on the functional recovery of limbs. In the traditional Chinese medicine therapy of humerus surgical neck fracture, the dynamic and static combination is taught through the arm-throwing therapy of skin traction, so that fracture healing is facilitated, and the limb function is recovered quickly.
