Abstract
The invention encompasses a bone screw for use in the human body including a shaft having a threaded region along at least a portion of its length and a screw head including a locking mechanism to secure the screw, for example to a bone plate. In certain embodiments, the thread has an outer diameter dimensioned to pass through the screw hole in the implant. The screw head is configured to cooperatively engage at least a portion of the screw hole of the implant so as to prevent the screw from coming out of the implant and avoided soft tissue damage and other complications associated with unintended screw removal.
