Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Such as Figure 1~4 As shown, a steel plate for the lateral column of the ulnar coronoid process includes a head 2 and a plate body 1. The head 2 and the plate body 1 are connected by a helical segment 3, and the helical segment 3 is twisted and transitioned from the plate body 1 to the plate body 2. As a result, the head 2 matches the anatomical shape of the protrusion at the upper end of the lateral column of the ulnar coronoid process, and the helical segment 3 matches the anatomical shape of the transition part between the above-mentioned protrusion and the lower end of the lateral column of the ulnar coronoid process.

[0023] The shape of the plate body 1 can be various. In this embodiment, in order to make the plate body 1 better fix the fracture site, the plate body 1 in this embodiment includes a T-shaped transverse support pla...

Abstract

The invention relates to an ulna coracoid process lateral column steel plate. The steel plate comprises a head portion and a plate body. The plate body comprises a cross support plate and a vertical support plate. The head portion is arranged above the cross support plate and is connected with the cross support plate through a spiral section, the included angle formed between the head portion and the cross support plate is in a range of 25 degrees to 30 degrees, and the included angle formed between the cross support plate and the vertical support plate is in a range of 155 degrees to 160 degrees. One to two first locking holes are formed in the vertical support plate and are third locking holes with internal threads or locking pressurizing holes formed by partial overlapping of pressurizing hole grooves and spiral hole portions. The steel plate is matched with the ulna coracoid process lateral column anatomic form, and accordingly, the steel plate can be attached to the fracture portion well, the broken bone face can be well fixed, and a good operation effect is obtained.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a steel plate for the lateral column of the coronoid process of the ulna. Background technique [0002] Posterior dislocation of the elbow, fracture of the coronoid process, and fracture of the radial head are known as the terrible triad. The coronoid process plays an important role in maintaining the stability of the anterior side of the elbow joint. It can be seen. [0003] Familiarity with the analysis of coronoid fractures is crucial for treatment. The currently widely used Regan-Morrey classification divides them into three types according to the height of coronoid fracture fragments on lateral X-ray films: type 1 fractures involving the coronoid tip, Type II fractures involve 50% or less of the coronoid height, and type III fractures exceed 50% of the coronoid height. In 2003, on the basis of the Regan-Morrey classification, O'Driscoll et al. added the types of fracture...
