The invention relates to the technical field of orthopedic medical devices, in particular to a functional combined fixer for distal radius fractures. The ball joint spring structure composed of screwing in the spring ball head, screwing in the spring rod, spring, internal and external threaded ball head bowl, lock pin slider with chute on both sides and ball top wire is a multi-directional and multi-angle wrist joint. The range of motion and flexibility provide the conditions. The outer hexagonal bowl, the bowl fastening cap, the bowl rod, the open lock needle wire, etc. are combined with the T-shaped lock needle structure and applied to the second metacarpal longitudinally through two threaded needles. Or make the best choice between the second metacarpal and the third metacarpal through a threaded needle in the horizontal direction. The hemispherical tooth surface bolt, the hemispherical tooth surface left and right screw nut, the left and right thread adjustment rod, the left and right rotation The angle-adjusting stable structure composed of screw nut bolts and left-right screw thread nuts can fix the wrist joint at a certain angle according to clinical needs, and it can be easily fixed with the angle to achieve a stable fixing effect, which greatly facilitates operation and Early functional mobility of the wrist joint.
