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 expandable implant is disclosed in which the implant includes top and bottom plates having angled inner surfaces that interact with expansion members. The expansion members may be situated on an actuator, and may include at least one vertical projection. In some instances, rotation of the actuator in opposing directions about a longitudinal axis may cause the expansion members to move toward or away from one another, thereby resulting in separation of the top and bottom plates. During such expansion of the implant, the at least one vertical projection of the expansion members may be guided at least partially within a recess formed in the first or second plate. Pins may also be included with the expansion members that ride along respective slots in the plates during expansion. An insertion instrument for implanting the aforementioned implant, and methods of using the same, are also disclosed.

Intervertebral implants, assemblies, and methods thereof. An intervertebral implant includes opposing chamfered edges to reduce a diagonal distance between the edges. The reduced diagonal distance minimizes distraction of an intervertebral disc space during insertion of the implant. A tool for insertion and rotation of the implant is also provided.

Devices and related methods for the dynamic correction of spinal deformities are disclosed. The devices and methods are particularly useful for correcting an abnormal curvature of the spine. In one exemplary embodiment, a method for correcting deformity via a spinal implant that can include a polymer between or attached to a top and bottom plate, which can exist in a wedge-shaped configuration in order to apply asymmetric forces to the spinal column, is provided. The implant may be inserted between adjacent vertebrae comprising part of the abnormal curvature, thereby restoring the normal curvature of a spine.

A joint implant system adapted for use in joint surgeries. Among other things, the joint implant has an anterior cutting edge and a rotatable cutter supported by a rotatable shaft.

A distally expanding facet joint implant and delivery device for distally distracting a facet joint. The facet joint implant generally includes an outer part and an inner part. The outer part includes a pair of opposed distally expandable facet plates connected by a hinge. The inner part includes a wedge that is selectively movable against the facet plates to distally expand and contract the facet joint implant into open and closed states. Teeth on the outer part engage indents on the inner part to maintain the facet joint implant in the distally expanded state. The outer and inner parts include outer and inner connectors, and the delivery device includes corresponding outer and inner connectors adapted to be in locked engagement with the outer and inner connectors to hold the implant and selectively cause it to distally expand and contract.

Resorbable implants, coverings and receptacles comprising poly(butylene succinate) and copolymers thereof have been developed. The implants are preferably sterilized, and contain less than 20 endotoxin units per device as determined by the limulus amebocyte lysate (LAL) assay, and are particularly suitable for use in procedures where prolonged strength retention is necessary, and can include one or more bioactive agents. The implants may be made from fibers and meshes of poly(butylene succinate) and copolymers thereof, or by 3d printing molding, pultrusion or other melt or solvent processing method. The implants, or the fibers preset therein, may be oriented. These coverings and receptacles may be used to hold, or partially/fully cover, devices such as pacemakers and neurostimulators. The coverings, receptacles and implants described herein, may be made from meshes, webs, lattices, non-wovens, films, fibers, foams, molded, pultruded, machined and 3D printed forms.

Methods and apparatus for providing correction of one or more maladies or conditions of the spinal column of a living being. In one embodiment, the apparatus includes an implantable device configured to be selectively adjustable in one or more portions thereof so as to permit correction of asymmetries or irregularities of the spinal column via insertion into one or more affected intervertebral disc spaces. In one variant, the implantable device includes upper and lower host elements which are hinged or can pivot relative to one another, and an insertable distraction mechanism which is adjustable to enable one side or the other of the implantable device to alter height. In another variant, both sides of the implantable device can be adjusted for height via the host elements and one or more pivots or hinges. In one implementation, the distraction mechanism is adjustable from multiple approaches into the disc space.

A multi-section expandable device includes an expansion module, a first push member and a second push member disposed at front and rear ends of the expansion module, and a bolt screwedly connected to the first and second push members. When the bolt is tightened, the first push member and the second push member are pushed to approach each other so as to push the expansion module to generate a first-stage expansion and a second-stage expansion. The first-stage expansion enables the expansion module to expand laterally so as to adjust its width. The second-stage expansion is performed after the expansion module is laterally expanded to have a maximum width, so that the expansion module is longitudinally expanded to adjust its height. The multi-section expandable device not only has better support effect, but also avoids the wear of the contact surfaces of the vertebrae.
