Bang: Isolated Infraspinatus Tear and Suprascapular Nerve Neuropathy after Barbotage and Steroid Injection of Calcific Tendinitis

Abstract

Isolated rupture of infraspinatus after barbotage for calcific tendinitis has not been reported in the literature. We report on a case of isolated infraspinatus rupture and suprascapular nerve neuropathy after steroid injection and barbotage of calcific tendinitis in rotator cuff. At 6-month follow-up after surgery, satisfactory clinical and radiological outcomes were observed with daily activity level. The author reports this case and review the literature.

(A) Magnetic resonance imaging showed that the distal region of the infraspinatus tendon had a full-thickness tear, while the proximal region was retracted medially past the glenoid cavity with fatty atrophy. (B) An incomplete full-thickness tear of the teres minor muscle was also present.
