Medical Imaging Study Of Frozen Shoulder In Diabetes Mellitus

Objective To explore whether ultrasound examination has the same clinical value as magnetic resonance imaging in the diagnosis of frozen shoulder of diabetes mellitus.The results of ultrasound examination were used to investigate whether there were differences in the thickness of the coracohumeral ligament(CHL)and the inferior capsule(IC)between diabetic frozen shoulder and primary frozen shoulder.To investigate whether there was difference in the thickness of the CHL and the IC in the patients with diabetes with different duration of frozen shoulder.Methods: The control group selected 30 patients with single primary frozen shoulder,called group A,that is,the primary frozen shoulder group;In the experimental group,20 patients with type Ⅱ diabetes mellitus(fasting blood glucose <7.2mmol/L)whose course of disease was <5 years,5-10 years and >10 years and clinically diagnosed as single diabetic frozen shoulder were selected respectively,which were called group B,C and D,and the sum of the three groups was called group E,namely diabetic frozen shoulder group.Thirty patients were randomly selected from group E,called group F,for ultrasound and magnetic resonance imaging of shoulder joint on the affected side,and the thickness of the coracohumeral ligament(CHL)and the inferior capsule(IC)were measured respectively,and the differences were statistically analyzed.Bilateral shoulder joint ultrasound was performed in group A,B,C and D respectively,CHL and IC thickness were measured respectively,and differences in CHL and IC thickness between the healthy side and the affected side were statistically analyzed within and between groups.Results :(1)there was no significant difference in CHL between ultrasound and magnetic resonance imaging in diabetic frozen shoulder(P>0.05).Diabetic frozen shoulder ultrasound and magnetic resonance imaging showed statistically significant differences in IC results(P<0.05),and there was a linear correlation between IC results measured by the two methods,with a correlation coefficient of 0.940(P<0.05).(2)CHL and IC of healthy and affected shoulder joints were significantly different in group A(original frozen shoulder group)and group E(diabetic frozen shoulder group),P<0.05;There was no statistically significant difference in CHL thickness of healthy shoulder between group A and GROUP E(P>0.05),while there was statistically significant difference in CHL thickness of affected shoulder between group A and group E(P<0.05).There were statistically significant differences in IC thickness between healthy side and affected side between group A and GROUP E,P<0.05.(3)There were statistically significant differences in CHL and IC thickness between healthy side and affected side of shoulder in group B(diabetes <5 years),group C(diabetes >10 years)and group D(diabetes >10 years),P<0.05;There was no significant difference in CHL thickness between healthy side and affected side of shoulder in group B,C and D,P>0.05;There were statistically significant differences in IC thickness between healthy side and affected side of shoulder in group B,C and D,P<0.05.(4)There was no significant difference in IC thickness between the healthy side and the affected side of shoulder in group B-C,P>0.05.There were significant differences in IC thickness between the healthy side and the affected side of shoulder in b-D group and C-D group,P<0.05.Conclusion: Ultrasound examination has the same high clinical application value as magnetic resonance imaging in the auxiliary diagnosis of frozen shoulder of diabetes mellitus.Compared with ultrasound examination,it is more simple,less cost,no contraindications,and can be widely promoted.Compared with the original frozen shoulder,the thickening degree of the inferior capsule and the beak-humeral ligament in diabetic frozen shoulder was more obvious.The inferior capsule thickened significantly in patients with diabetic frozen shoulder,and the inferior capsule was more likely to be involved than the coracohumeral ligament in patients with diabetic frozen shoulder.
