Scapular-fracture anatomical locking internal fixation system

Abstract

The invention discloses a scapular-fracture anatomical locking internal fixation system. The system includes a scapular lateral border steel plate and a scapular medial border steel plate, the scapular lateral border steel plate includes a scapular glenoid part and a lateral border part, the scapular medial border steel plate includes a scapular spine part and a medial border part, lateral / medial border parts of the steel plates are attached to lateral / medial border parts of the scapula, the scapular spine part is attached to the human-body scapular spine part, and the scapular glenoid part is an arc steel plate matched with the human-body scapular glenoid part; a fixation part of the scapular glenoid part, a fixation part of the lateral border part, a fixation part of the scapular spine part and a fixation part of the medial border part are both provided with a plurality of screw holes. By the adoption of the scapular-fracture anatomical locking internal fixation system, fracture parts of the lateral and medial of the scapula can be ideally attached and fixed, the adjustment on the steel plates in surgeries can be avoided, or the attachment of the scapular surfaces can be achieved simply through slight adjustment, the surgery time and risks are reduced, and the scapular-fracture anatomical locking internal fixation system is conductive to good facture recovery. The scapular lateral border steel plate and the scapular medial border steel plate can be used independently or in a combination mode according to patients' conditions, and resource waste caused by clipping is avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an anatomical locking internal fixation system for scapula fractures. Background technique [0002] The scapula is located on the outer upper part of the back, and its shape is irregular, including two faces, three corners and three borders, of which the subscapular fossa is a large and shallow fossa in the front; The spine of the scapula, the shallow fossa above and below the spine, are called the supraspinatus fossa and the infraspinatus fossa respectively. The lateral end of the spine of the scapula is called the acromion, which is the highest point of the shoulder; the lateral horn is thick and has a pear-shaped articular surface, which is called the joint The upper and lower corners of the glenoid are located at the upper and lower ends of the medial border, parallel to the second and seventh ribs respectively, which can be used as a sign for counting r...

AI Technical Summary

Problems solved by technology

The muscle groups around the scapula are tightly attached, and surgical exposure is difficult. It is difficult to deal with fracture reduction, especially comminuted fracture fragments, and it is difficult to achieve anatomical reduction. In addition, traditional fixation instruments need to be shaped during the operation to be more compliant with the bone surface. On the one hand, prolonging the operation time increases the blood loss and the risk of infection during the operation. On the other hand, bending, cutting and other shaping will lead to a decrease in the rigidity and stability of the internal fixation device, and the fixation effect is not reliable, resulting in fracture malunion, Complications such as delayed fracture union
