Definition[Bearbeiten]
The scaphotrapezium ligament is a strong ligament between the Os trapezium and the distal surface of the Os scaphoideum.
Function[Bearbeiten]
Together with the scaphocapitate ligament, the scaphotrapezium ligament stabilises the distal pole of the scaphoid in the proximal carpal row and at the same time enables sliding movements against the trapezium bone.
Clinic[Bearbeiten]
A rupture of the scaphotrapezium ligament in combination with a previous dislocation can lead to a complete dislocation of the scaphoid from the joint.
