The osseous shoulder is comprised scapula, and clavicle. The of the proximal humerus, soft-tissue structures of shoulder are more complex, including several muscles, tendons, ligaments, and cartilaginous structures working in synchrony to move and support the shoulder.

Methods: 120 patients with shoulder injury who were treated in our hospital (January 2020 to December 2021) and underwent surgical treatment were diagnosed as shoulder injury. They were divided into CT group, MRI group and joint diagnosis group. The detection rates of the two methods were compared. Results: In the diagnosis of shoulder injury, MRI group was higher than CT group, and the joint diagnosis group was higher than the other two groups. Conclusion: In the diagnosis of shoulder injury, the joint examination of multi-slice spiral CT and magnetic resonance imaging (MRI) can obtain a higher diagnostic rate and ideal effect.展开更多
