Mitt type cervix metacarpal fracture fixing support instrument

Abstract

The invention relates to a mitt type cervix metacarpal fracture fixing support instrument, belonging to orthopaedics medical instruments. The invention mainly comprises a mitt provided with sticky hair tapes and buckling tapes, and is characterized by also comprising a cushion board with a slope-shaped spongy cushion and a tape board, the end face of the slope-shaped spongy cushion is provided with hook tapes fitting with the sticky hair tapes on the back of the mitt; two ends of the tape board are respectively provided with hair tapes, the hair tapes on one end are fit with the buckling tapes and those one the other end are fit with the hook tapes on the back of the cushion board. The invention is suitable for cervix metacarpal fracture with head of metacarpal bone shift towards the palm side, thus having exact fixing effect and comfortable wearing and not influencing normal motions of fingers and wrist joints.

Description

technical field [0001] The invention relates to an orthopedic medical device, in particular to an external fixation support for maintaining the reduction of metacarpal neck fracture. Background technique [0002] Metacarpal neck fractures in the hand are very common, especially fifth metacarpal neck fractures, also known as "boxer's fractures". Clenching a fist and hitting a hard object is a common cause of metacarpal neck fractures. The tendency of fracture displacement is that the metacarpal head is pulled by the muscles to move to the palm side, and the fracture end will appear dorsal angle. Failure to properly reduce and fix the metacarpal head will cause the collapse of the metacarpal head, which will affect the appearance and function of the hand. The current clinical treatment is plaster external fixation after closed reduction or surgical Kirschner wire internal fixation. Because of the poor fixation effect of the small splint bandage, it is rarely used clinically....

AI Technical Summary

Problems solved by technology

Because of the poor fixation effect of the small splint bandage, it is rarely used clinically.

However, the effect of external fixation with plaster is not exact, and fractures often redisplace, and the plaster is heavy, and it is easy to loosen and fail after being exposed to water. The plaster fixation also needs to fix the wrist joint and adjacent fingers at the same time, which obviously causes inconvenience to life and work.

Although the internal fixation of metacarpal neck fracture with Kirschner wire surgery is more reliable, it is an invasive treatment after all, which will bring the risk of needle tract infection, and the cost is high, and the patient's compliance is poor.

At present, many patients with metacarpal neck fractures do not have comfortable and effective external fixation, and do not accept surgical internal fixation, resulting in malunion of the fracture in the case of displacement, which has a certain impact on the appearance and function of the hand
