Heterotopic ossification of the supraspinatus tendon after rotator cuff repair: case report.

Heterotopic ossifications of the shoulder are uncommon. Rarely, these ossifications are seen after open or even arthroscopic shoulder surgical procedures. Here, we report a patient who underwent a rotator cuff repair, complicated with an axillary nerve paralysis. Postoperatively he developed substantial ossification of the supraspinatus tendon. A review of the literature was done. To our knowledge no other cases similar to this have been reported.
