What is the "Elbow Lateral Pivot-Shift Test" used for?
Lateral Ulnar Collateral Ligament Injury (PLRI)
How to perform the "Elbow Lateral Pivot-Shift Test"?
Patient lies supine with affected arm overhead
Forearm is supinated and valgus stress is applied while bringing the elbow from full extension to 40 degrees of flexion
With increased flexion triceps tension reduces the radial head
Often more reliable on anesthetized patient.
What is the positive result?
At 40° of flexion, the patient with posterolateral rotatory instability will note apprehension/pain as the radial head subluxates about the capitellum.
With further flexion, a clunk or sense of relief occurs as the joint is reduced.
