zone of injury
Anatomical classification system for flexor tendon injuries based on location within the finger.
Full Definition
The zone of injury classification system divides the finger into five anatomical zones to describe flexor tendon injuries and guide treatment decisions. Zone I involves the FDP tendon distal to the FDS insertion. Zone II, historically called 'no man's land,' encompasses both tendons within the fibrous flexor sheath. Zone III includes the lumbrical origin in the palm. Zone IV covers the carpal tunnel area, and Zone V involves the forearm. Each zone presents unique surgical challenges and prognosis.
Usage
Usage note: Capitalize 'Zone' when referring to specific anatomical zones (Zone I, Zone II, etc.). Zone II historically called 'no man's land.'
In Context
- "The flexor tendon laceration occurred in Zone II, requiring immediate surgical repair." — emergency surgery note
