Middle phalanx - Proximal, collateral ligament avulsion

back to Hand overview

Glossary

General considerations

Collateral ligament avulsions usually occur as a consequence of a bending force on the digit. Most of these are not associated with a gross joint instability and can be well treated closed. However with significant displacement the joint can be unstable. Surgery is usually indicated for significant displacement and/or joint instability.
