dart-thrower's motion
A combined wrist movement pattern involving simultaneous radial deviation with extension and ulnar deviation with flexion, representing functional wrist motion.
Full Definition
Dart-thrower's motion describes a natural, functional movement pattern of the wrist that combines radial deviation with extension and ulnar deviation with flexion along an oblique plane. This motion pathway represents the most common functional movement pattern used in daily activities and sports, following the path from radial extension to ulnar flexion. Understanding this motion is crucial in wrist arthrodesis procedures, where maintaining this functional arc while limiting painful motion planes can significantly improve outcomes. The concept has influenced surgical approaches to partial wrist fusions and rehabilitation protocols following wrist injuries.
Usage
Usage note: Always include apostrophe in 'dart-thrower's' and use hyphens to connect the compound terms.
In Context
- "The four-corner arthrodesis was designed to preserve dart-thrower's motion while eliminating painful midcarpal motion." — Surgical planning note
- "Rehabilitation focused on restoring dart-thrower's motion rather than individual plane movements." — Physical therapy protocol
