An implant system, alignment guide, bone fusion system and surgical method for correction of a flat foot or rocker-bottom deformity, such as a Charcot foot. The implant system includes a bone implant and an elongate member. The bone implant includes a proximal end, a distal end, a hole along a longitudinal axis, and at least one opening intersecting the hole. The elongate member includes a first end with a head portion, a second end with a coupling mechanism, and an opening along a longitudinal axis. The coupling mechanism of the elongate member engages the at least one opening to couple the bone implant to the elongate member.

An implant having a joint facing surface and a bone facing surface forming a body member and a dorsal member therebetween. The implant further having a ring member extending out from the bone facing surface to a free end disposed for insertion into a bone recess. The body member and the dorsal member include a concave curvature on the bone facing surface and a convex curvature on the joint facing surface.

A device for the repair of a phalangeal joint comprises a first anchor, a second anchor, and a flexible spacer connecting the first and second anchors. The flexible spacer comprises a plurality of elongate fibers extending axially or criss-crossed between the first and second anchors and a polymeric matrix interspersed with the plurality of elongate fibers. Specifically, a prosthetic metatarsophalangeal joint device comprises a porous metallic metatarsal bone anchor, a porous metallic phalangeal bone anchor, and a polymeric spacer element comprising parallel or criss-crossed elongate fibers that can connect the metatarsal bone anchor and the phalangeal bone anchor. Methods for manufacturing prosthetic joint devices comprise using three-dimensional printing processes or molding processes. Methods for implanting prosthetic joint devices comprise positioning porous metallic anchor components adjacent resected bones at planar interfaces and between which a polymeric spacer having axial aligned elongate fibers embedded in a matrix can be disposed.

Orthopedic implants having a bone interface member and a water swellable IPN or semi-IPN with a stiffness, hydration, and/or compositional gradient from one side to the other and physically attached to the bone interface member. The invention also includes an orthopedic implant system including an implant that may conform to a bone surface and a joint capsule. The invention also includes orthopedic implants with water swellable IPN or semi-IPNs including a hydrophobic thermoset or thermoplastic polymer first network and an ionic polymer second network, joint capsules, labral components, and bone interface members. The invention also includes a method of inserting an orthopedic implant having a metal portion and a flexible polymer portion into a joint, including inserting the implant in a joint in a first shape and changing the implant from a first shape to a second shape to conform to a shape a bone.

The invention provides a method of making a biological disc graft. In one embodiment, the biological disc graft is useful for treating back or neck pain. In one embodiment, the biological disc graft is useful for treating any joint pain. The invention also provides a method of implanting said biological disc graft in a way that is minimally invasive and less dangerous.
