Abstract:
1. A surgical fixation device, comprising: a base portion including an aperture constructed and arranged to receive a graft configured to replace a ligament or tendon, the base portion having a contact surface at a first side and being constructed and arranged to contact a bone at the contact surface and secure the graft relative to the bone surface; and a securing portion constructed and arranged to secure the graft to the base portion, the securing portion being arranged to engage with the base portion on a second side of the base portion opposite the contact surface and extending from the second side in a direction away from the contact surface of the base portion, the securing portion having a part that extends across the aperture without occluding the aperture when the securing portion is engaged with the second side of the base portion; wherein the base portion and the securing portion are arranged to be deployed entirely within a bone opening and to anchor the graft relative to bone in the bone opening to resist tension experienced by a replacement ligament or tendon where the tension is applied on the graft, while the graft is secured to the securing portion and passes through the aperture, in a direction from the securing portion toward the contact surface, wherein the base portion and securing portion are arranged to receive the graft such that a portion of the graft passes through the aperture, extends along a first side of the securing portion toward a distal end of the securing portion, passes over the distal end of the securing portion, and then extends along a second side of the securing portion away from the distal end and back through the aperture, and wherein the securing portion is configured to expose the graft to bone in the bone opening along at least a portion of a length of the securing portion when the graft is anchored by the surgical fixation device relative to bone in the bone opening.
