AI Technical Summary

Technical Problem

In the prior art, after the ulna coronary process fracture is performed through the anterior approach, the stability of the anterior part of the elbow joint is poor, the local soft tissue is irritating, the fixation intensity of contact with the coronary process of the ulna coronary process is low, the postoperative healing effect is poor, and the volume stress fracture occurs.

Method used

A ulna coronary process bone junction plate with anterior approach is designed, adopting a T-shaped structure, including an adapter plate and a fixing plate, and an angle connection between the adapter plate and the fixing plate. The adapter plate is used to adapt to the distal lateral column of the ulna coronary process, and suture holes and adjustment holes are set to improve fixing strength and stability and reduce stress concentration.

Benefits of technology

It improves the contact area and fixation strength of the bone junction plate and the coronal process of the ulnar bone, reduces the stimulation of local soft tissue, promotes fracture healing, reduces the risk of stress fractures, and enhances functional recovery after surgery.

Abstract

The utility model discloses an ulna coracoid process bone fracture plate through anterior approach, bone setting of ulna coracoid process is achieved through anterior approach, the bone fracture plate is of a T-shaped structure, the total length of the bone fracture plate is smaller than 2.5 cm, the bone fracture plate comprises an adaptive plate and a fixing plate which are in angle connection, the adaptive plate is located above the fixing plate, the adaptive plate is used for being matched with a far-end lateral column of the ulna coracoid process, and the fixing plate is used for being matched with the far-end lateral column of the ulna coracoid process. The adaptive plate comprises a positioning hole and suture holes formed in the two sides of the positioning hole; the fixing plate is narrower than the adaptive plate, an adjusting hole and a fixing hole are formed in the fixing plate, the adjusting hole is located between the positioning hole and the fixing hole and used for achieving adaptive adjustment of the bone fracture plate and the far-end outer side column, and the total length is the total distance between the top end of the adaptive plate and the bottom end of the fixing plate. According to the bone fracture plate, the matching stability of the bone fracture plate and the front portion of the elbow joint after bone fracture is improved, stimulation to local soft tissue is reduced, the contact area between the bone fracture plate and ulna coracoid processes is increased, the fixing strength between the bone fracture plate and the ulna coracoid processes is improved, the postoperative healing effect is improved, and the stress fracture risk is reduced.
