Description

Wrist joint fixing brace capable of assisting in functional exercise

Technical Field

The utility model relates to a medical appliance, in particular to a medical rehabilitation appliance.

Background

Distal radius fractures are common, accounting for about 1/6 total fractures. The wrist joint is the most complex joint in the human body and is also the most important joint with the highest frequency of activity of the whole body. The injury mechanism of the distal radius fracture is complex, the fracture types are various, and the conservative treatment mode of the distal radius fracture with different types and injury mechanisms is roughly as follows: straightening type fracture (ColIes fracture): most of them are injuries when the wrist joint is in the dorsal extension position, the palm is on the ground and the forearm is in the pronation, local pain and swelling after the injuries, the far end of the fracture is shifted to the radial side and the dorsal side, and the near end is shifted to the palmar side. The palm is fixed in flexion after reduction. (iii) flexion type fractures (Smith or reverse Colles fractures): rarely, it is often caused by the back of the hand being injured by the wrist joint flexing and the back of the hand falling down. The proximal end is shifted to the back, the distal end is shifted to the palm and the radius, the direction of the shift is opposite to that of the extension fracture, and the fixation of the back extension is needed after the reduction. And thirdly, no displacement fracture and reduction are needed, and the neutral position is fixed.

The wrist joint is fixed in different bending and stretching directions according to the requirements of an injury mechanism, and the fixed angle is adjusted according to the requirements of the disease course. Although some patients have healed, the function of fingers and the grip strength are seriously hindered.
