Abstract: A shape-memory alloy orthopedic implant includes a bridge having a curved longitudinal axis, a first end, and a second end opposite the first end. The bridge has a radially outer surface extending axially from the first end to the second end. In addition, the orthopedic implant includes a first leg extending from the first end of the bridge. The first leg has a central axis, a fixed end fixably attached to the bridge, a free end distal the bridge, and a radially outer surface extending axially from the fixed end of the first leg to the free end of the first leg. Further, the orthopedic implant includes a second leg extending from the second end of the bridge. The second leg has a central axis, a fixed end fixably attached to the bridge, a free end distal the bridge, and a radially outer surface extending axially from the fixed end of the second leg to the free end of the second leg.

Abstract: A staple apparatus can include a base member substantially coplanar to a first axis and a second axis perpendicular to the first axis. The base member can include a trapezoidal shape including two substantially equal length sides and two unequal length sides, the two unequal length sides comprising a first side and a second side with the first side being shorter than the second side and the first side being parallel with the second side on the first axis. The base member can include an aperture passing through a center point of the base member, a first indentation in the first side, and a second indentation in the second side. The staple apparatus can include a first pair of legs protruding from the first side of the base member and a second pair of legs protruding from the second side of the base member.

Abstract: An example orthopedic implant includes a bridge, a plurality of torsion regions coupled to the bridge, and a plurality of legs coupled to and extending from the plurality of torsion regions. The plurality of legs are configured to transition between a first position and a second position, and in the second position, the plurality of legs are angularly displaced relative to the first position. In addition, the legs are biased toward the first position by elastic torsional stresses in the plurality of torsion regions when the legs are in the second position.
