Estimating the term…
The present invention relates to a wing-shaped angle steel plate and a bone shaft fixation system. The wing-shaped angle steel plate comprises a wing fitting portion and a body fixation portion which are fixedly connected to each other. The wing fitting portion is used for supporting a fracture end and has a structure matched with an inner side surface of a bone shaft. The body fixation portion is used for fixing the wing fitting portion and has a structure matched with a front side of the bone shaft. The body fixation portion is provided with at least two first locking holes for passing through first locking screws at an intersection site with the wing fitting portion and is further provided with at least two second locking holes for passing through second locking screws in the structure matched with the front side of the bone shaft. In the wing-shaped angle steel plate, the wing fitting portion and the body fixation portion of the present invention are connected to each other and cooperate to fix and support the bone shaft fracture end site, and effectively ensure and help stable reduction and healing of the fracture sites.
