Varus/radial stress test Flashcards
What does the radial stress test diagnose?
Laxity / instability of radial collateral ligament
What is the rationale behind the radial stress test?
By applying varus force to the wrist, the lateral joint space is gapped & the radial collateral ligament is put under tension.
This may show laxity or reproduce symptoms
What does a positive result identify?
Instability of the radial collateral ligament
Procedure of radial stress test
1) Explain & IC
2) Patient sat with elbow flexed to 90, forearm and palm resting face up on a table
3) Physio stabilises wrist proximal to joint line & applies varus force onto hand (move into ulnar deviation)
4) Monitor the degree of gapping/laxity and observe the patient’s face for signs of discomfort
5) Compare to other side
Positive result of radial stress test
Laxity and / or pain over the radial border of the wrist joint
Suggests instability of the radial collateral ligament of the wrist.
Negative result of radial stress test
No demonstration of laxity or pain on testing.
Result: Laxity and / or pain over the radial border of the wrist joint
What does this mean?
instability of the radial collateral ligament of the wrist
