A 55-year-old female with a history of type 1 diabetes, reports increasing pain and stiffness in the right shoulder. She recently experienced immobilization of the right arm for a  hairline fracture following a fall. The pain is diffuse and increased with any type of activity. During physical exam right shoulder weakness and reduced passive and active range of motion are noted. Upon palpation of the joint area, diffuse tenderness is noted without crepitus. The exam is otherwise unremarkable.  What condition is most likely the cause of her symptoms?
