Distal radius fracture traction reduction fixing support

Abstract

The invention discloses a distal radius fracture traction reduction fixing support. A traction glove, a palm splint and a back splint are connected through a traction rod, confrontation traction is formed at the two ends of a fracture part, and therefore the effect of further reduction and fixation of the fracture is achieved, an air bag and fluff are innovative key points, autotraction is achieved through the design, The generated effects comprise that the height of the distal radius articular surface can be kept, the traction direction can be adjusted according to situation changes, movementof wrist joints and all joints away from the wrist joints is allowed on the basis of maintaining reset, the hand function of a patient is reserved as much as possible, and therefore the rehabilitation effect is guaranteed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a traction reduction fixation brace for distal radius fractures. Background technique [0002] Distal radius fractures are common clinically and account for the highest proportion of orthopedic emergency fracture patients. 17% of women over 50 years old will suffer from distal radius fractures. With the continuous extension of human life expectancy and the continuous improvement of the quality of life requirements, the treatment of distal radius fractures has received more and more attention. However, how to choose the correct treatment method is still controversial. At present, the main treatment methods are the following three kinds: closed reduction plaster or splint fixation, closed reduction Kirschner wire or stent external fixation, open reduction internal fixation with plates and screws. When plaster fixation is used for Kopier’s fractures, the wrist joint is usually fixed ...

AI Technical Summary

Problems solved by technology

When plaster fixation is used for Kopier’s fractures, the wrist joint is usually fixed in volar flexion and ulnar deviation after manual reduction, and then changed to neutral position after 2-3 weeks, while small splint fixation usually does not exceed 4-6 weeks of wrist joint fixation. The fixation method is often the first choice for elderly patients due to its advantages of simplicity, almost non-invasiveness, and low cost. However, fracture reduction is lost, the height of the articular surface cannot be maintained, long-term swelling of the wrist (small splint fixation can even cause severe swelling), and fracture malunion It is common for patients to undergo effective functional exercises in the early stage and it is difficult to carry out effective functional exercises in the early stage, which ultimately leads to weakness, pain, stiffness and limited mobility of the wrist joints. Although surgical treatment has certain advantages in terms of stability and functional recovery after fracture reduction, it is still This difference is not obvious in elderly patients, and there are still risks or disadvantages such as blood vessel, nerve, tendon injury, infection, prolonged hospitalization time and high cost

[0003] At present, there are some patent designs trying to improve the traditional gypsum or small splint technology, which we like to see, but there are still some defects in these designs. For example, the Chinese utility model patent with the authorization notification number CN 201064510Y discloses a "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 it cannot adjust the deflection angle of the radial and ulnar side. More importantly: the height of the articular surface of the distal radius cannot be maintained (especially for comminuted fractures). It is very common for the traditional fixation method to lose the fracture reduction and reduce the articular surface height of the distal radius in the later stage. The recovery effect is very large, even in internal fixation surgery this is the main reason for poor postoperative results

The Chinese invention patent with the authorized notification number CN 103054666B discloses a "distal radius fracture external fixation treatment device", which tries to solve the problem of lower articular surface height of the distal radius. At the place where the force is applied, the locking belt must be tightened first when using it, and then the problem will follow: the stress can only be concentrated on the locking belt of the palm sleeve, thus artificially creating a ring tie, the far end How to ensure the blood circulation of limbs? How to deal with cutaneous nerve compression? Most of these fractures occur in elderly women. Due to the low level of estrogen, the skin on the hands is thin, the subcutaneous fat is scarce, and obviously lacks elasticity. This design causes a high probability of side damage to the user's skin, and it is difficult to achieve the purpose of treatment.
