Spontaneous scapular spine fracture related to rotator cuff pathology: a report of two cases.

Spontaneous fractures of the scapula are rare, especially those involving the scapular spine. There are only a few case reports addressing this topic. Two cases are presented of spontaneous scapular spine fractures in patients with cuff-tear arthropathy. Treatment was conservative, resulting in a stiff shoulder in both patients. The combination of oral steroids and cuff-tear arthropathy seems to have caused a spontaneous scapular spine fracture in these patients. Considering the risk of operative intervention in the elderly patient conservative treatment seems a reasonable alternative.
