Tenodesis fixation method

摘要

A tendon anchoring device may include an implant having a pair of spaced apart legs for straddling a tendon. A push rod removably attached to the implant may be utilized to guide and push a portion of the tendon into a pre-drilled bore in a bone. A fixation member may be slid along the push rod and threadably engage an inner surface of the pre-drilled bore to thereby anchor the tendon to the bone while a force is applied to the push rod. Once the fixation member has been installed, the push rod may be disengaged from the implant and removed from the bore. The implant may remain permanently straddled over the tendon inside of the bore.

1. A method of anchoring a tendon to a bone of a patient, the method comprising:
forming a bore in the bone; and anchoring the tendon in the bore using an implant and a fixation member, wherein the implant is fixedly attached to an end of a push rod; wherein the implant includes a body member and a pair of legs, each of the pair of legs extending from the body member and terminating at a free end, the pair of legs defining a straddle for laterally confining the tendon within the bore; wherein the implant is disposed in the bore between the fixation member and a bottom surface of the bore; wherein the implant comprises a substantially planar top surface formed on the body member opposite the pair of legs, the top surface comprising a pair of oppositely disposed, concave edges and a pair of oppositely disposed, convex edges; wherein a length of the concave edges of the top surface are greater than a length of the convex edges of the top surface.
