Description

Technical Field

[0001] The present application relates to orthopedic instruments, and in particular to a hook structure for fixing distal clavicle fractures. Background Art

[0002] With the continuous development of transportation and economy in modern society, the pace of life has accelerated, the incidence of distal clavicle fractures has increased significantly, and bone and surrounding soft tissue injuries have also tended to worsen. Traditional fracture internal fixation has many defects and the therapeutic effect is unsatisfactory.

[0003] After a distal clavicle fracture, the distal clavicle fixation plate cannot effectively fix the distal fragment for patients with small or severely comminuted distal fracture fragments. Traditional fixation methods mostly use clavicle hook plates or reconstruction of the coracoclavicular ligament. Titanium plate hooks are placed under the acromion, which can easily lead to postoperative pain, shoulder joint dysfunction, bone cutting at the acromion site, resulting in acromion damage, and in severe cases, deformity and nonunion of the bone after the fracture. This affects subsequent rehabilitation and the therapeutic effect is unsatisfactory. Reconstruction of the coracoclavicular ligament does not stimulate the subacromial process, but it cannot directly fix the fracture, resulting in malformation, nonunion, and delayed healing. Summary of the invention

[0004] The purpose of the present invention is to provide a hook structure for fixing distal clavicle fractures, which is mainly used for fixing distal clavicle fractures.

[0005] To achieve the above object, the present invention provides the following technical solutions.

[0007] Preferably, in the above-mentioned hook structure for fixation of distal clavicle fracture, the extension direction of the second screw hole is designed according to the needs of the patient.

[0008] Preferably, in the above-mentioned hook structure for fixing distal clavicle fractures, the side plate is connected to the first plate body by two first screws arranged opposite to each other.
