Published: Dec 14, 2023

Perilunate dislocations are serious wrist injuries that can have long-lasting consequences if not treated promptly. Understanding this condition is crucial for anyone involved in high-impact activities or sports.

How Does It Happen?

These injuries typically result from high-energy trauma, such as a fall from a height onto an outstretched hand. Imagine your wrist as a shock absorber - in a severe impact, the force can cause the bones to shift out of place.
