Implants, devices, instruments, kits and methods for correcting bone deformities in the foot are disclosed. Specifically, implants, devices, instruments, kits and methods used for lower extremity osteotomy procedures are disclosed.

An intramedullary assembly for intraosseous bone fusion includes a lag screw member and a tapered screw member. The lag screw member includes a first elongated body, where the first elongated body includes a first threaded portion at a first end and a bulbous portion at a second end. The tapered screw member is coupled to the lag screw member, and the tapered screw member includes a second elongated body, where the second elongated body includes a second threaded portion at a third end, and an opening at a fourth end.

Assemblies of one or more implant structures make possible the achievement of diverse interventions involving the fusion and/or stabilization of the SI-joint and/or lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. The representative lumbar spine interventions, which can be performed on adults or children, include, but are not limited to, SI-joint fusion or fixation; lumbar interbody fusion; translaminar lumbar fusion; lumbar facet fusion; trans-iliac lumbar fusion; and the stabilization of a spondylolisthesis.

Devices and methods are disclosed for joint replacement.

Orthopedic implants having a bone interface member and a water swellable IPN or semi-IPN with a stiffness, hydration, and/or composition 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 of a bone.

Bone fusion system, plate system, guide, implant, kit and methods for using the bone fusion system, plate system, guide and implant are disclosed. The bone fusion system includes an alignment guide, an implant, and at least one fastener inserted through the implant. The alignment guide includes a body portion, a first lobe positioned at a first end of the body portion, a second lobe positioned at a second end of the body portion, and an extension member extending away from a first side of the body portion. The implant includes a body portion, a first arm extending away from the body portion in a first direction, a second arm extending away from the body portion in a second direction, and a third arm extending away from the body portion laterally between first and second arms. Finally, methods for using the bone fusion system, plate system, guide and implant are disclosed.
