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.

ABSTRACT

Objective To evaluate the diagnosis of frozen shoulder with the coracohumeral ligament on the coronal oblique plane with MRI.Methods There were 60 patients(120 shoulder joints)in control group,with 30 males and 30 females,the mean age was 50.5 years old.There were 72 shoulder joints in 72 patients of frozen shoulder group(50 femles and 22 males with a mean age of 53.5 years)with clini-cal evidence and MR imaging evidence of frozen shoulder.These were prospectively analyzed to identify the CHL visualization rate and meas-ure the maximum thickness of the CHL.Results The CHL visualization rate on the coronal oblique plane in the control group was 86.7%(104 /120),and the frozen shoulder group was 87.5%(63 /72),the difference was not significant(P >0.05).The CHL visualization rate on the axial view in the frozen shoulder group was 19.4%(14 /72)and the control group was 24.2%(29 /120),the difference was not signifi-cant(P >0.05).The CHL thickness on the coronal oblique plane (n =63)in the patients with frozen shoulder was (4.37 ±1.71)mm, which was significantly greater than (2.84 ±0.79)mm ofpatients in the control group(n =104),the difference was significant(P <0.001). The CHL thickness on the axial plane(n =14)in the patients with frozen shoulder was (3.93 ±1.49)mm,which was significantly greater than (2.29 ±0.65)mm of patients in the control group(n =29),the difference was significant(P <0.001).Conclusion A thickened CHL is highly suggestive of frozen shoulder,which is 4.37 mm on the coronal oblique plane.

ABSTRACT

OBJECTIVE: To evaluate the difference of coracohumeral ligament (CHL) thickness between asymptomatic shoulders and adhesive capsulitis. METHOD: Ultrasound examination was performed in 44 consecutive shoulders of 24 individuals (12 males and 12 females). Nine were diagnosed as adhesive capsulitis by clinical examination. We measured the maximum thickness of CHL. For CHL assessment, participants were scanned in sitting position with shoulder in maximal external rotation, elbow in 90 degrees flexion, forearm in neutral position, and hand in fist. The transducer was positioned between coracoid process and greater tuberosity of humerus. We used t test to compare the CHL thickness between asymptomatic and adhesive capsulitis and bivariate correlation analysis to assess a correlation between age and CHL thickness. RESULTS: There was a significant positive linear relationship between age and CHL thickness (p<0.01, gamma=0.424). In female, there was a positive linear relationship between age and CHL thickness (p<0.01, gamma=0.610). However, in male, there was no significant correlation (gamma=0.224). The mean value of CHL thickness was 1.53 mm in 9 adhesive capsulitis and 0.92 mm in 35 asymptomatic ones. CHL thickness was significantly greater in adhesive capsulitis than in asymptomatic ones (p < 001). CONCLUSION: The thickened CHL is a good suggestive diagnostic value of adhesive capsulitis.
