Abstract
Bone anchors and bone anchor insertion systems are provided that enable smaller bone holes for inserting a bone anchor by eliminating the need for a cannula. Smaller bone holes may help reduce patient recovery times. The provided bone anchor includes two flexible wings extending from a base portion that splay away from the base portion's central axis at rest, though may be bent towards or away from the central axis in response to an applied force. The bone anchor includes a drive feature that enables an inserter to couple and decouple to the bone anchor. A surgeon may drive the bone anchor through a bone hole via the coupled inserter while the bone hole maintains the bone anchor in a compressed state, and may decouple the inserter when the bone anchor is properly positioned, thereby eliminating the need for a cannula.
