1. Fractures of the triquetrum occur infrequently.
2. Chip, flake, traction, or avulsion fractures of the dorsal aspect of the triquetrum often do not unite and may form a permanent ossicle; those that do unite usually take several months to do so.
3. Fissure and comminuted fractures of the main part of the triquetrum almost always unite without gross deformity; non-union is rare and aseptic necrosis apparently does not occur.
4. It must be emphasized that clinical or functional recovery usually occurs long before roentgenographic evidence of bony union is demonstrated.
