Fatigue (stress) fracture of acromion after reverse total shoulder

Our shoulder fellow Anastastios Papadonikolakis has provided a very interesting case and gave us permission to show it here.

An 80 year old had a reverse total shoulder for rotator cuff tear arthropathy. At three months he was very pleased with his comfort and function.

Subsequently he developed pain over his posterior shoulder at the scapular spine. While plain films did not show a problem, CT scan and 3-D reconstruction revealed a stress or fatigue fracture at the base of the acromion, as shown by the arrows in the figures below.
This has been the topic of a previous post and points out the need to be aware of this problem in individuals who develop posterior shoulder pain after this procedure.
