Abstract
ABSTRACT:
BACKGROUND:
Adhesive capsulitis is a common illness-causing scapula-humeral pain with decrease in range of movement in the shoulder joint. MRI gives clear images about the joint capsule, the coraco-humeral ligament (CHL), and any associated pathology.
OBJECTIVE:
To study value of MRI for early diagnosis of adhesive capsulitis in diabetic patients through recognition of increased thickness of CHL.
PATIENTS AND METHODS:
Fifty-four adult participants were included in this study, 33 were females and 21 were males, their mean age 45.5 (age range 22-67 years), divided into 2 groups. The patient group included 34 diabetic patients (24 female and 10 male) with a mean age of 51.0±9.0, with first complain of shoulder pain, stiffness ± limitation in range of movement for about 8 to 12 weeks in duration, MR images were interpreted and analyzed from an oblique sagittal and coronal T1 WM-TSE. The control group included 20 healthy cases (9 female and 11 male) with a mean age of 43.0±11.4.
RESULTS:
A statisticallysignificant difference in CHL thickness between the diabetic patients and the control group, mean CHL thickness in diabetic patients is 2.80±0.71mm (range 1.18-4.20) in comparison with 1.78±0.29mm (range 1.20-2.20) in control group. In the patients group, female were more affected than male (70.9% to 29.4%respectively) when compared to the control group (female 45.0%, male 55%). The study also shows a statisticallysignificant difference in the rotator interval between the diabetic cases (mean 1.62±0.18cm) and control cases (mean 1.90±0.26cm). The best cut-off value of CHL thickness is (2.15mm) with a sensitivity of 91.2% and specificity of 90.0%.
CONCLUSION:
A significantly positive correlation was found between CHL thickness, rotator interval, and adhesive capsulitis. Thus, MRI study for CHL thickness in early adhesive capsulitis in diabetic patients can be sensitive and specific.
