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.

Figure

• 

  Fig. 1. The calcific deposit (arrow) in the subacromial space is almost completely resorbed.

• 

  Fig. 2. (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imaging showed that the distal region of the infraspinatus tendon had a full-thickness tear, while the proximal region was retracted medially past the glenoid cavity with fatty atrophy.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.

• 

  Fig. 3. (A) An infraspinatus tear accompanied by calcification was observed. (B) Arthroscopic infraspinatus tendon repair was performed using knotless anchor suture.

• 

  Fig. 4. (A) Arthroscopic suprascapular nerve release was performed using metal trocar. (B) The dotted line shows suprascapular nerve compressed by scapular spine. SP: scapular spine, IST: infraspinatus.

• 

  Fig. 5. Magnetic resonance imaging of 6 months following surgery showed that the infraspinatus tear was repaired (A) and that infraspinatus muscle mass was slightly increased (B).

• 

  Fig. 6. Relationships of suprascapular nerve and scapular spine. If the infraspinatus tendon was retracted, suprascapular nerve will be compressed by scapular spine. Arrow: suprascapular nerve, arrow head: suprascapular artery.
