Bent dip fusion screw

摘要

Devices and methods are disclosed for the fusion of joints (particularly finger joints or toe joints) in a bent (or angled) position. In certain embodiments, the device is pre-bent and inserted into the joint in its pre-bent configuration. Alternatively, the device may be configured to have a first position wherein it is bent and a second position wherein it is straight. In that case, the device is preferably straightened by inserting a K-wire through a cannula in the device, and the device can be inserted into the joint in its straight position. Once inserted, the device is permitted to move to its bent position, which moves the joint to a bent position. In one embodiment the device moves to its bent position when the K-wire is removed.
