extensor tenodesis
A passive stabilization technique using extensor tendons to restore digit position.
Full Definition
Extensor tenodesis is a surgical procedure that uses the natural tension of extensor tendons to provide passive positioning of digits when active extension is lost. The technique involves fixing the extensor tendon at appropriate tension so that wrist flexion produces passive digit extension through the tenodesis effect. This procedure is commonly used in tetraplegic patients to restore functional hand positioning and improve activities of daily living. The success depends on preserving wrist extensor function and achieving proper tension balance.
Usage
Usage note: Distinguish from active tendon transfers which provide voluntary motion.
