The relationship between the fracture of the clavicle which was fixed by torsional-shaped plate and nonunion

Objective To discuss the relationship between the fracture of the clavicle which was fixed by torsional-shaped plate and nonunion after operation. Methods Retrospective analysis was conducted in 426 patients with midshaft clavicle fractures.Among the patients, the A group used torsional-shaped plate to meet the anatomical structure of the clavicle: the medial plate matched under the front face of the clavicle, and the lateral plate matched the up face of the clavicle.And the traditional method was used in the B group.Patients were followed up for at least 12 months, the patients were judged by X-ray criteria for nonunion. Results A total of 28 patients with nonunion, including 4 cases in A group, 24 cases in B group.After statistics processing, the difference between A group and B group was significant (χ2=6.679, P=0.010). Conclusion We find that the treatment of the fracture of the middle part of the clavicle with torsional-shaped plate can effectively reduce the incidence of nonunion.
