An adjustable wedge can be used in an Evans technique foot and ankle reconstructive wedge surgery. The adjustable wedge can include a slide. The slide can be positioned to a suitable location on a patient's calcaneus, then fastened to the calcaneus through first and second holes through the slide at opposite ends of the slide. The adjustable wedge can include a body having a pair of wedged surfaces configured to contact the cutout of the calcaneus. The body can include a slot extending between the wedged surfaces. The slot can be sized to accommodate the slide so that the slide is slidable within the slot. A circumferential surface can extend circumferentially between the wedged surfaces. A threaded hole can extend through the circumferential surface to the slot. The threaded hole can receive a fastener, such as a set screw, to secure the slide to the body.

Arthroplasty implant systems and procedures are disclosed herein. In an embodiment, an arthroplasty implant of an arthroplasty system includes a shape memory material connecting member attached to two points of fixation of the arthroplasty implant.

An implant is provided for use in an ankle joint between reconditioned end surfaces established on a distal end of an upper tibia bone and an opposing lower talus bone. The implant comprises a substantially porous rigid component adapted to be anchored against the upper tibia reconditioned end surface and the lower talus reconditioned end surface. The component defining an opening therethrough. An intramedullary nail is configured to pass through the opening in the component when the nail is driven through the talus and into the tibia.

The present invention provides an implant in a form of a truss, spanning the distance from diaphysis of the tibia to the tip of the calcaneus, thus fixing the ankle (hock) joint in extension. Gastrocnemius muscles are thus at close to their shortest length and their force capacity is greatly reduced, preventing the caudal luxation of the distal femur even if the cranial cruciate ligament is torn.

A subtalar joint implant system that includes a first implant component and a second implant component is disclosed herein. An alternative embodiment of a subtalar joint implant system is disclosed and includes a first component that has threads disposed on at least a portion of an exterior surface of the first component and a second component having threads disposed on at least a portion of the exterior surface of the second component. The first and second components are each configured to couple with at least a portion of a talus and a calcaneum of a patient with the first component being configured to couple with at least a portion of a posterior facet of the calcaneum of the patient and the second component being configured to couple with at least a portion of a middle facet of the calcaneum of the patient.

An ankle implant for use in ankle arthroplasty in total ankle replacement is provided. The implant includes an upper prosthesis anchored to the tibia and a lower prosthesis anchored to the talus. The lower prosthesis is operable associated with the upper prosthesis. The implant also includes a stem which is rigidly removably connected to the second member. The stem includes a portion for attachment to the calcaneous. The stem is be adapted to be in a first position in the calcaneous when the stem is in a first relative position with respect to the lower prosthesis, and to provide for a second position in the calcaneous when the stem is in a second relative position with respect to the lower prosthesis.

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.

A system for modifying a talocalcaneal spatial relationship in a foot in a body, including a subtalar spacer having an articulating surface and implanted in the sinus tarsi of the foot and a fastener that fastens the subtalar spacer to a bone surface in the foot, in which the articulating surface of the subtalar spacer directs relative movement between the calcaneus and the talus of the foot.

An replacement for a human includes a body having a superior surface, an inferior surface, a distal surface, and a proximal surface. The proximal surface is configured to engage the talus and the calcaneus of an adult human, and the distal surface configured to engage at least the first and fourth metatarsals of the adult human. The distal surface has a largest distal height and a largest distal width that is greater than the largest distal height, and the proximal surface has a largest proximal height and a largest proximal width that is greater than the largest proximal height.
