Abstract:
Objective To investigate the MR features of different clinical staging of scapulohumeral periarthritis and provide relevant support data for the clinical staging of scapulohumeral periarthritis, so as to guide clinical treatment. Methods 30 patients with scapulohumeral periar-thritis received in the hospital from June 2015 to February 2017 were selected to form the observation group and 8 same-sex and same-aged volunteers without such disease were selected to form the control group. MR imaging was used to observe and measure the structure of shoulder joint of the people in the two groups and statistical analysis was performed to analyze the changes in the structure of the shoulder around dif-ferent clinical stages. Results The thickness of joint capsule and coracohumeral ligament ( CHL) , the ratio of subcoracoid fat triangle re-placed were significantly greater in patients with scapulohumeral periarthritis than those in the control group, and the difference was statisti-cally significant (P<0. 05). Comparing the thickness of joint capsule in the third stage of the scapulohumeral periarthritis group compare with those in the first and second stages, the difference was statistically significant (P<0. 05). There was no statistically significant differ-ence (P>0. 05) in the thickness of the coracohumeral ligament and the ratio of subcoracoid fat triangle replaced in the scapulohumeral peri-arthritis group between the 1st, 2nd and 3rd stages. Conclusion Patients with different stages have different structures around the shoulder joints. The thickness of joint capsule can be used as an important reference for diagnosing scapulohumeral periarthritis and can guide the clin-ical staging. The thickness of coracohumeral ligament and the ratio of subcoracoid fat triangle replaced can be used as a basis for diagnosing scapulohumeral periarthritis, but it cannot be used as a guideline for clinical staging.
