A toe implant (10) for a first metatarsal phalangeal joint (22) between a metatarsal (24) and a proximal phalanx (26) of a great toe (12) includes a proximal stem (16), a distal stem (18) and a hinge (20) and a strength rib (92). Importantly, the toe implant (10) is designed to accommodate an axis of motion in a unique location (82) and the distal stem (18) is naturally positioned lower than the proximal stem (16). Further, the toe implant (10) provides a relatively good available range of motion. With this design, the toe implant (10) maintains the proximal phalanx (26) in the correct anatomic position relative to the metatarsal (24) during bending and flexing. Additionally, the toe implant (10) allows the toe (12) to move in a fashion that simulates the natural motion of the first metatarsal phalangeal joint (22). As a result thereof, the toe implant (10) that does not significantly increase the stress at the joint (22) or alter the normal flexing of the toe (12).
A toe implant for a toe, the toe implant comprising:
A toe implant for a toe, the toe implant comprising:
A toe implant for a toe, the toe implant comprising:
A toe implant for a toe, the toe implant comprising:
An implant comprising an implant body including a proximal stem having a proximal axis, a distal stem, a hinge and a strength rib, the hinge being positioned between and connecting the proximal stem to the distal stem, the hinge including a hinge center section, wherein the strength rib extends along only a portion of the hinge center section of the hinge and does not extend completely across the hinge center section, wherein the rib has a length perpendicular to the proximal axis that is approximately equal to a width perpendicular to the proximal axis of the proximal stem near the hinge, wherein the length of the rib is substantially parallel to the width of the proximal stem.
