AI Technical Summary

Technical Problem

The prior art is difficult to effectively fix the extremely distal radial fracture, especially when the fracture line affects the pulmonary side of the lunar fossa, the fixation is not firm and reduction loss is prone to occur.

Method used

A fractured bone plate of the extremely distal radius is designed. A multiple reserved holes are provided at the distal end of the bone plate. The reserved holes extend from the dorsal side of the radius to the palmar side of the radius and are incised upwards. A multiple fixing holes are provided on the main body to form a "T"-shaped structure to enhance the fixing effect.

Benefits of technology

Through the design of inclined reserved holes, K-Spirit pins or screws form a longer working length in the radius, enhancing the fixation effect of the fracture block; the inclination angle of the locking hole is consistent with the radial palm inclination angle, which conforms to the ergonomic characteristics, further improving the fixation stability.

Abstract

The utility model discloses a radius extremely-far-end fracture bone fracture plate which comprises a bone fracture plate far end and a main body part, the bone fracture plate far end is located above the main body part, a plurality of reserved holes are formed in the bone fracture plate far end, and the reserved holes extend from the back side of the radius far end to the palmar side and are obliquely cut upwards. A plurality of fixing holes are formed in the main body part. When the bone fracture plate is used, the bone fracture plate is fixed to the distal palm side of the radius, the reserved hole in the distal end of the bone fracture plate is mainly used for fixing a meniscus fossa palm side fracture block far away from a watershed, a matched kirschner wire with threads can be selected to penetrate through the reserved hole, meanwhile, the reserved hole can be used as a screw hole, and a matched screw with a proper size is adopted to penetrate through the reserved hole for fixing. Due to the fact that the preformed hole is inclined from top to bottom, a kirschner wire or a screw is inclined from top to bottom to penetrate through the radius downwards, a long working length is formed in the radius, and a good fixing effect can be achieved.
