Medial and Lateral Collateral Ligament of the Fingers

The medial and lateral collateral ligaments of the fingers are important stabilizing structures located on the sides of each finger joint. They help control sideways movements, preventing the finger from bending or bowing excessively in either direction. The medial collateral ligament is on the inner side of the finger, while the lateral collateral ligament is on the outer side. These ligaments work together to maintain proper joint alignment during movement and help prevent injuries such as sprains or dislocations, allowing the finger to function smoothly and securely during everyday activities.
