Abstract
Bone fixation methods and devices with an elongate body having a longitudinal axis and having a flexible state and a rigid state, a plurality of grippers, a rigid hub connected to the elongated body, and an actuator operably connected to the grippers to deploy the grippers from a first shape to an expanded second shape. One method can include inserting a bone fixation device into an intramedullary space of the bone to place at least a portion of an elongate body of the fixation device in a flexible state on one side of the fracture and at least a portion of a rigid hub on another side of the fracture, and operating an actuator to deploy a plurality of grippers of the fixation device to engage an inner surface of the intramedullary space to anchor the fixation device to the bone.
