Description

Traction reduction fixing support for radius distal end fracture

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a radius distal end fracture pulls fixed brace that resets.

Background

Distal radius fractures are common in clinic, and are the highest among orthopedic emergency fracture patients, and distal radius fractures occur in 17% of women over 50 years old. With the continuous extension of human life expectancy and the continuous improvement of the requirements for living quality, the treatment of distal radius fractures is increasingly emphasized, however, the choice of the right treatment method is still controversial. The main treatment methods at present are the following 3: the closed reset plaster or the small splint is fixed, the closed reset kirschner wire or the bracket is fixed outside, and the reset steel plate screw is opened for internal fixation. The plaster is usually used for fixing the wrist joint in a palm bending and ulnar deviation way after manual reduction in the case of Coco's fracture, the fixing is changed into a neutral position fixing after 2-3 weeks, and the small splint is usually not more than the wrist joint fixing for 4-6 weeks, the fixing mode has the advantages of simplicity, convenience, almost no wound and low cost, which is often the first choice of old patients, but the fracture reduction is lost, the articular surface height cannot be maintained, the wrist is usually swollen for a long time (the small splint is fixed and even causes severe swelling), the fracture deformity healing conditions are common, the effective functional exercise is difficult to be carried out in the early stage, and finally the wrist joint of the patient is weak, painful, stiff and limited in activity, while the operation treatment generally has certain advantages in the aspects of stability and functional recovery after the fracture reduction, but the difference is not obvious in the old patients, and blood vessels, nerves and the wrist, Tendon injury, infection, prolonged hospitalization, high cost, and the like.

At present, some patent designs try to improve the traditional plaster or small splint technology, which is what we are happy, but these designs still have some defects, for example, the chinese utility model patent with the publication number CN 201064510Y discloses an "adjustable external fixator for distal radius fracture", this design realizes the adjustment and fixation of the wrist joint at different flexion and extension angles through the hinge structure of the splint at the wrist joint, but cannot adjust the oblique angle of the ulnar and radial, and more importantly: the height of the distal joint surface of the radius cannot be maintained (particularly for comminuted fracture), the situations that fracture reduction is lost and the height of the distal joint surface of the radius is reduced in the later period of the traditional fixing mode are very common, the situation has a great influence on the function recovery of the wrist joint, and even in internal fixation surgery, the situation is also the main reason for poor postoperative effect. The Chinese patent of the patent publication No. CN 103054666B discloses an external fixation treatment device for distal radius fracture, which aims to solve the problem of height reduction of the distal radius articular surface, and the design uses a palm sleeve as a stress part for drawing the distal radius fracture, and when in use, a locking belt must be tightened, so that the problems follow: stress can only be concentrated on the locking band of the palm sleeve, so that a cerclage band is artificially created, how can blood circulation of the distal limb be ensured? How does the cutaneous nerve become stressed? Most of the fractures occur in the elderly women, and due to the low estrogen level, the hand skin is thin, the subcutaneous fat is rare, and the elasticity is obviously lacked, so that the probability of the skin side injury of a user is very high, and the treatment purpose is difficult to realize.
