Range of motion of diabetic frozen shoulder recovers to the contralateral level.

Abstract

ObjectiveTo determine whether frozen shoulder heals equally well in patients with and without diabetes and whether dependency on insulin affects the outcome.MethodsWe retrospectively examined 178 patients with idiopathic frozen shoulder; 27 patients had diabetes. We evaluated range of motion, pain, and functional results. The mean follow-up was 9.7 years (SD, 7.1 years).ResultsIn the presence of frozen shoulder, range of motion did not differ between patients with and without diabetes. At follow-up, range of motion in all directions of both the affected and unaffected shoulders of patients with diabetes was inferior to that of patients without diabetes. Among patients with diabetes, range of motion of the once-frozen shoulder reached the level of the unaffected shoulder. Patients with and without diabetes experienced similar pain except during exertion. The Constant–Murley score was not significantly different between the two groups, and insulin dependency did not lead to worse outcomes.ConclusionFrozen shoulder heals well in patients with diabetes.
