Isolated suprascapular nerve injury below the spinoglenoid notch after SLAP repair

Abstract

Suprascapular nerve neuropathy is frequently reported as being caused by a cyst of the spinoglenoid notch of the scapula. It can be also caused by a complication of open surgical procedures requiring dissection of the posterior shoulder joint. The transglenoid suture technique for the Bankart repair can injure the suprascapular nerve if the drilling is performed too deep and without sufficient caution. We describe a case of isolated infraspinatus atrophy due to suprascapular nerve injury below the spinoglenoid notch by improper anchor insertion during the superior labral anterior posterior (SLAP) repair.
