External fixation treatment device for distal radius fracture

Abstract

The invention discloses an external fixation treatment device for distal radius fracture. The external fixation treatment device for the distal radius fracture comprises a forearm palmar splint for attaching to and fixing the palm side of the forearm of a patient, an inner side splint, an outer side splint, a forearm dorsal splint for attaching to and fixing the upper side of the forearm of the patient, wherein the inner side splint and the outer side splint are used for attaching to and fixing the inner side and the outer side of the forearm of the patient. The forearm palmar splint, the inner side splint, the outer side splint and the forearm dorsal splint are bound on the periphery of the forearm of the patient so as to fix strip-shaped components of the hand and the forearm circumferentially. The external fixation treatment device further comprises a palm cover for wrapping the palm of the patient and elastic inserting strips for performing flexible limit and extension on the forearm relative to the wrist joint of the patient. The elastic inserting strips are respectively connected between the palm cover and the forearm dorsal splint, the palm cover and the inner side splint, the palm cover and the outer side splint and the palm cover and the outer side of the forearm palmar splint.

Description

【Technical field】 [0001] The invention relates to a medical device, in particular to an external fixation treatment device for distal radius fractures. 【Background technique】 [0002] 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 extension 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 reduc...

AI Technical Summary

Problems solved by technology

[0003] 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

[0004] 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 patients' diagnosis and treatment costs, aggravated 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.

[0005] 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 splint fixation 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. Reported and researched
