Problems solved by technology

Practice has proved that the use of thoracobrachial plaster external fixation method is complex, bulky, and has poor air permeability, which affects the patient's breathing and rest. Due to the high incidence of shoulder joint injury, the shoulder joint function is limited, which brings pain and inconvenience to the patient.
However, the use of the existing fixation frame also generally has the disadvantages of unstable fixation and the inability to adjust the tightness. The shoulder joint is in a drooping position for a long time, and local soft tissue fibrosis is prone to occur, causing shoulder muscle atrophy and affecting the function of the shoulder joint.

Abstract

The outer fixer for upper arm fracture includes upper arm bearing plate, front arm bearing plate, front breast wall fixing plate, back breast wall fixing plate, front arm regulating rod, front arm supporting rod and L-shaped upper arm supporting rod. The present invention maintains two 90 deg abductions of shoulder and elbow joints to resist gravitational force and shoulder musculus abductor tension force to maintain the fracture paraposition dynamically, avoid replacement and speed fracture healing. The present invention is firm and reliable and has no influence on the breath and sleep of the patient.

Description

technical field [0001] The invention relates to a medical device for external fixation of fractures, in particular to an external fixator for upper arm fractures. Background technique [0002] Upper arm fracture is a common orthopedic disease. Shoulder joint injury and upper humerus fracture are more difficult to treat due to their severity. Reasonable fixation is one of many problems. The treatment method one that usually adopts at present is manipulative reduction, thoracobrachial plaster external fixation, and the 2nd, adopts the special fixing frame that is made of bracing frame, supporting plate. Practice has proved that the use of thoracobrachial plaster external fixation is complicated, heavy, and poor in air permeability, which affects the patient's breathing and rest. Due to the high incidence of shoulder joint injuries, the shoulder joint function is limited, which brings pain and inconvenience to the patient. However, the existing fixation frame also generally s...
