Patent attributes
A fixation system configured to releasably secure an orthopedic implant to a bone. The orthopedic implant has at least one lumen extending from a proximal portion to a distal portion configured to extend through cortical portions and into cancellous portions of the bone. The fixation system includes a flowable biomaterial that flows through the lumen into the cancellous portion of the bone in an expanded configuration with at least one dimension greater than a corresponding dimension on the orthopedic implant located generally along a pull-out direction of the orthopedic implant. An insert is positioned in the lumen and in engagement with the flowable biomaterial located in the cancellous portion of the bone, such that the orthopedic implant is detachable from the biomaterial in the cancellous portion of the bone to facilitate subsequent removal of the orthopedic implant from the bone.
