Synonyms
- Terry Thomas (David Letterman) sign: scapholunate ligament disruption with interspace widening = mimics wide gap between front teeth
Definitions
- Intrinsic ligaments: connecting 1 carpal bone to another
- Extrinsic ligaments: capsular thickenings connecting carpals to metacarpals, radius, or ulna
- Intercarpal ligament disruption
- Relates to scapholunate ligament (SLL) and lunotriquetral ligament (LTL)
