QS Syndrome or Rotator Cuff Tear? Use These Test Clusters

Quadrilateral Space Syndrome: A Sneaky Duck

This quick review is a continuation of the previous blog about quadrilateral space syndrome; the great mimicker of rotator cuff and other shoulder pathologies.

Here’s a quick tip on “clustering” examinations to rule in/out a rotator cuff tear:

There’s a 98% probability of full thickness rotator cuff tear when a patient has 3 or more of the following: 1

  • Supraspinatus weakness (Empty Can or Drop Arm)
  • Weakness in resisted external rotation (External Rotation Lag Sign)
  • Positive signs of impingement (Neer’s, Hawkins-Kennedy).
  • Patient is over the age of 60

While MRI can be helpful, findings can often be misleading since many people have tears demonstrated on a scan that are asymptomatic.2
