Left wrist is shown in all photos. Arrows indicate direction of stress application. A Normal wrist showing application of dorsaldirected stress to the distal ulna with the forearm fully pronated to assess integrity of deep palmar radioulnar ligament. B Unstable wrist demonstrating marked translation of distal ulna with dorsal-directed stress indicating incompetent deep palmar radioulnar ligament. C Normal wrist showing application of palmar-directed stress to the distal ulna with the forearm fully supinated to assess integrity of deep dorsal radioulnar ligament. D Unstable wrist demonstrating marked translation of distal ulna with palmar-directed stress indicating incompetent deep dorsal radioulnar ligament.

• Dorsopalmar Stress Test
• Dorsal Palmer Stress Test
• Distal Radioulnar Joint Stress Test

---

Purpose

• Evaluate the distal radioulnar joint as a cause of the patients wrist pain

---

Description

• Requires examination in neutral, pronation and supination
  • Compare ulnar translation on the injured side to uninjured site
• Pronated forearm
  • Examiner applies a dorsally directed stress to the distal ulna, stabilizing the radius
  • Laxity indicates injury to the deep palmer radioulnar ligament
• Supinated forearm
  • Examiner applies a palmerly directed stress test to the distal ulna, stabilizing the radius
  • Laxity indicates injury to the deep dorsal radioulnar ligament
• Normal test
  • Firm end points without side-to-side laxity compared to unaffected limb
