A triquetral fracture involves a break in the triquetral bone which is one of the 8 small carpal wrist bones. Remember that the triquetral bone is the second most damaged carpal next to the scaphoid.
What are the indications?
If an individual is suspected with a triquetral fracture, the following symptoms are present:
- Wrist pain after trauma, impact or falling onto an extended hand.
- Pain on the pinky finger side of the wrist
- Rapid swelling and tenderness if the site of the fracture is pressed
- Diminished grip strength and range of motion
Wrist pain after trauma, impact or falling onto an extended hand.
What are the causes?
A triquetral fracture typically occurs after a fall onto an extended hand, particularly if the wrist is extended and if bent backwards and tilted. A direct strike from a blunt, hard object on the rear of the wrist can also cause the injury.
A fracture can also occur in isolation without other associated injuries. Nevertheless, they are often complicated and might include other fractures such as the lunate as well as soft tissue injuries and fractures.
Management of a triquetral fracture
Once a fracture is suspected, it is vital to seek immediate medical care. An X-ray is usually required to confirm a diagnosis and exclude any associated injuries.
When it comes to an isolated triquetral fracture, it usually heals properly with immobilization. The wrist is placed under a cast for up to 6 weeks so that the bone can heal. After this phase, the cast is taken out and exercises are started to restore full movement and strength of the wrist.
