Primary Repair of Chronic Ulnar Collateral Ligament Injury of Thumb Metacarpophalangeal Joint

Chronic metacarpophalangeal joint injury of the thumb is a common condition presenting as pain or instability.

We believe reconstruction is not necessary and primary repair can be performed. This technique describes identifying the ligament in a chronic injury and repairing it primarily.
