Abstract
A bioabsorbable suture anchor for anchoring soft tissue to a bone is provided. The suture anchor is configured to toggle and anchor itself inside a bone cavity of a small joint. The anchor comprises an elongate body defined by a longitudinal axis, a first, leading end and a second, trailing end. The elongate body also has two opposed surfaces between the first and second ends, and a plurality of sidewalls extending between the two opposed surfaces. Extending from one of the sidewalls is a flared portion that is formed on the second end of the elongate body. The flared portion is adapted to engage and anchor into bone tissue upon toggling. A suture channel extends between the two opposed surfaces. The suture channel is formed in the elongate body for passage of a suture strand therethrough, such that pulling on an attached suture strand effects toggling of the anchor inside a bone cavity.
