Introduction:

The wide range of motion and poor bone stability make the shoulder joint dislocation more than any other large joint. Yet, there is still a controversy about type of shoulder joint injuries in different ages, this study was conducted with the aim of evaluating the demographic and etiologic features of shoulder surgery.

Materials and methods:

This descriptive cross–sectional study was performed on all patients who underwent shoulder surgery during six–month period in Tabriz Shohada Hospital. The collected data by questionnaire included demographic information, history of disease and previous surgery, time, type and cause of injury, and changes in tissue.

Results:

In this study, 117 patients were studied( 64% males and 36% females) and the most abundant group was 25 to 34 years old. In 57% of the cases, the right shoulder was damaged and falling was the most common mechanism of responsible injury (44.4%). The most common injury was labrum and articular capsules injury (40.2%); then injury of rotator cuff (34.2%).There was no significant relationship between gender and type of injury (P = 0.245.There was a significant correlation between age and type of injury (P <0.001).

Conclusion:

 The incidence of shoulder injuries was higher in men. The most common injuries were labrum, articular capsules and rotator cuff injuries respectively. Also, there was no relationship between gender and type of injury; so there was a significant relationship between age and type of injury.
