Valgus Instability Stress Test

Medial Collateral Ligament Tear

Source: Physiotutors

Execution

  1. 1Position the patient with the elbow slightly flexed, about 20° to 30°, to unlock the olecranon.
  2. 2Stabilize the arm at the elbow with one hand.
  3. 3Place the other hand above the patient’s wrist.
  4. 4Apply an abduction or valgus force to the distal forearm.
  5. 5Palpate the medial collateral ligament and compare pain, laxity, ROM, and end feel with the opposite side.

Positive outcome

Excessive valgus opening, pain, instability, or a soft end feel is positive for medial collateral ligament sprain or tear. The test is most meaningful when compared with the contralateral elbow.

CommentMagee’s static valgus test checks medial ligament laxity, but subtle throwing-related MCL injury may be missed. Pain and laxity must be interpreted separately because pain may occur without measurable opening. Compared with the moving valgus stress test, diagnostic-accuracy support is weak.

Low Clinical Value
