Lateral Pivot-Shift Test of the Elbow
- Lateral Pivot-Shift Test of the Elbow is used for Lateral Ulnar Collateral Ligament Injury (PLRI)
- 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
- 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.
- Sensitivity: 100 % (In anesthetized patients)
- Sensitivity: 38 % (In awake patients)
