Description

External fixation device for controlling vertical separation displacement of upper-middle fracture of adult humerus

Technical Field

The utility model relates to an external fixation device for controlling fracture, in particular to an external fixation device for controlling vertical separation displacement of upper segment fracture in adult humerus.

Background

Fractures of the middle-upper part of the humerus are common clinical symptoms, mainly including acute traumatic fracture and senile osteoporosis fracture of teenagers. Young people choose surgical treatment, namely adopting steel plate screws or intramedullary nail internal fixation. The elderly are mainly treated by conservation therapy, namely plaster or splint external fixation. If the patient is not properly treated, the daily life of the patient is affected in the later period, and a heavy burden is brought to families and society. In the conservative treatment, the middle-upper fracture of the humerus is subject to muscle atrophy and relaxation due to long-term braking, and then is subjected to the influence of gravity, so that the broken end of the bone is easily subjected to vertical separation and displacement, and if the fracture cannot be controlled in time, the fracture is easily subjected to delayed healing and non-healing, and the function of the affected limb is easily affected. Because the middle upper fracture of the humerus is close to the shoulder joint, the position is special, the external fixation is difficult to operate, the clinical fixation always needs the joint nesting fixation of gypsum and splints, the fixation of the inner splints controls the lateral displacement, and the outer layer is overlapped with the super shoulder and elbow U-shaped gypsum to control the separation displacement of the broken ends of the bones. The discomfort of the fixed back shoulder and the upper arm is obvious, and is difficult for some patients to accept. Sometimes, the external fixation position is required to be frequently re-diagnosed and adjusted, so that fracture displacement is more easily caused, the risk of non-healing is increased, the burden of a patient is increased, and clinical medical resources are consumed.
