Passive ulnar deviation

Procedure.

Pull the subject’s wrist to the ulnar side until the end of range is reached.

Common mistakes.
The thumb is induded in the movement:

it should be left free to avoid excessive stretching of the tendons of the extensors and long abductor.

Normal functional anatomy:

• Rallge: about 45°
• Elld-fee/: rather hard WRIST 51
• Limifillg sfmcfllres: radial collateral ligament.

Common pathological situations:

• Pain at the radial side at full range is present in a sprain of the radial collateral ligament or as the result of gliding of tendons in an inflamed sheath in tenovaginitis of abductor pollicis longus and extensor pollids brevis(de Quervain’s disease).
• Pain at the ulnar side can be elicited by a lesion of the triangular fibrocartilaginous complex.
