The pronator contracture syndrome: A new entity in supination restriction.

Forearm rotation is essential for daily activities and functional dexterity, involving both pronation and supination. Forearm rotation limitations can result from various pathologies, often linked to trauma, structural changes in radio-ulnar joints, and interosseous membrane alterations. Soft tissue contracture, such as post-burn scarring or specific neurological conditions, can also restrict forearm rotation. We present two cases of painless restricted passive and active supination, devoid of bony, neurovascular, soft tissue, or congenital abnormalities. We describe a surgical technique to improve forearm rotation in these patients. [ABSTRACT FROM AUTHOR]
