Pitfalls of nonoperative treatment

Hyperextension of the DIP joint
Do not attempt to immobilize the joint in hyperextension. This can compromise the precarious vascularization of the skin of the dorsal aspect of the joint and might provoke ischaemia and possible necrosis.

Immobilization of the PIP joint
Do not immobilize the PIP joint as this may result in flexion contraction of the joint.
