Abstract
Implants, devices, systems, and methods for achieving ligament fixation are disclosed. An implant is disclosed that includes a head member, a breakaway portion, and an anchor member. The anchor member may be coupled to the head member by the breakaway portion. The implant may be designed to fail in fatigue at the breakaway portion. The breakaway portion may thereby extend between a first end of the anchor member and a second end of the head member. The breakaway portion may comprise a circumferential groove. The groove may be configured to concentrate stress forces in situ such that a fatigue failure/fracture occurs at the groove. Insertion instruments for inserting an implant for ligament fixation are also disclosed. Methods of using an implant for achieving ligament fixation are also disclosed.
