Nonoperative treatment
Main indications
Small fragment (<10% of articular surface), stable joint
Advantages
- Avoiding joint stiffness

Avulsion fractures result in marked joint instability.
If the fracture is not displaced and the joint is stable, nonoperative treatment is usually indicated.
Displaced unstable fractures must be stabilized with K-wires, a lag screw, or an intraosseous cerclage wire.
If the fracture is severely comminuted with multiple tiny fragments, it may be preferable to excise the fragments and reattach the collateral ligaments directly to the bone.
