Description

External fixation treatment device for distal radius fracture

【Technical field】

The invention relates to a medical device, in particular to an external fixation treatment device for distal radius fractures.

【Background technique】

Fracture of the distal radius is the most common fracture of the upper extremity. Fracture of the distal radius usually refers to a fracture within 3 cm of the distal end of the radius. The distal radius is involved in the formation of the wrist joint. Fracture of the distal radius is a common orthopedic trauma in clinical practice. In the event of an accident, people will subconsciously use it for support, so the wrist is easily injured. Since 1406 AD, orthopedic doctors have performed manual treatment based on the characteristics of the dorsal displacement of the straight fracture. It was not described until 1814 in the Western medicine of Abraham Colles. Fixed, to surgical treatment. Surgical treatment includes Kirschner wire fixation, external fixation stent fixation, various open reduction and internal fixation methods, miniature intramedullary nail fixation, balloon dilation reduction and bone grafting and open reduction under the guidance of wrist arthroscopy .

The traditional treatment methods for distal radius fractures often use surgical treatment, splint or wrist plaster external fixation to treat distal radius fractures. The general splint fixation method is not very stable, which makes the treatment effect unsatisfactory and may lead to easy secondary fractures. Secondary injury, leading to complications such as fracture malunion and joint dysfunction; while the effect of plaster external fixation is not accurate, often redisplacement of fractures, and the plaster is heavy, easy to loose and fail after being exposed to moisture, plaster fixation needs to be fixed at the same time Wrist joints and adjacent fingers obviously cause inconvenience in life and work; surgical fixation for radial fractures is more reliable, but it is an invasive treatment after all, which will bring the risk of needle tract infection, and the cost is high. Compliance is also poor.

In short, external fixation with splint or wrist plaster can only solve the fixation, but it is difficult and inconvenient to adjust after fracture fixation; after fixation, the shortening of the radius cannot be effectively prevented, and the stability of the radius after reduction is relatively poor, which is easy If the displacement occurs, in order to further restore the fracture shape, it is often necessary to perform another reduction. If the reduction is ideal, the above-mentioned possibility of fixation and displacement still exists. If the reduction is not ideal, surgical treatment will have to be performed. Increased the cost of diagnosis and treatment of patients, increased medical burden. As a result, at present, many patients with radial bone do not have comfortable and effective external fixation, and do not accept surgical internal fixation, resulting in malunion of fractures in the case of displacement, which seriously affects the work and life of patients.

In comparison, manual reduction and external fixation with small splints is the most convenient, cheap and widely used treatment method, especially in rural areas and places where urban and rural combined medical conditions are lacking, manual reduction and splint fixation has become the only treatment plan, but The disadvantages of splinting need to be avoided as much as possible clinically. Manipulative reduction and splint fixation is a traditional treatment method in the Department of Orthopedics and Traumatology of Traditional Chinese Medicine. We have been studying how to improve the technique for thousands of years. There are reports and studies.
