A tibial implant may include a plurality of geometrically conformal implant subunits. The implant subunits may be configured for individual insertion within a wedge-shaped-void of the tibia. The implant subunits may further be configured for assembly in order to provide an implant substantially covering an exposed portion of cortical bone formed when performing a surgical osteotomy. In some embodiments, some or all of the plurality of subunits may be mechanically interlocked with each other. Methods and kits for insertion and assembly of implants are further described.

A long-pitch, helical anchor includes splines radially extending and helically progressing circumferentially around and along the arcuate length of a curved center line (central curve). The center line may progress along the curved length of the anchor with all splines meeting near the center line. In other embodiments, the center line passes along the center of a lumen or channel from which the splines extend radially along the length. A solid point acts as a cutting edge on a distal end of the anchor. All the splines converge to the center line. Installation may be with or without a stabilizing frame, such as may be used to fill gaps and promote bone growth between joined members. The anchors may be used directly to connect and provide compression between two bones or bone structures.

This glenoidal component for a shoulder prosthesis comprises a base which may be immobilized on the glenoid cavity of a shoulder, and an element provided to be mounted on this base and forming a convex surface of articulation centred on an axis of symmetry. This axis of symmetry is non perpendicular to a rear face of the base intended to abut against the glenoid cavity, this making it possible to compensate a defect in parallelism between the resectioned surface of the glenoid cavity and the axis of the patient's spinal column. A surgeon can select the component in which the axes of symmetry of the components are oriented differently with respect to their rear faces.

The present disclosure includes implant systems, devices, and implants. The interbody spacers including a first endplate, a second endplate, and a coupling member coupled to and extending between the first endplate and the second endplate. Methods of using the interbody spacers are also disclosed.

The invention relates to a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

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.

A spinal facet fusion implant comprising: an elongated body having a distal end, a proximal end and a longitudinal axis extending between the distal end and the proximal end, the elongated body being characterized by a superior body surface and an inferior body surface; a superior stabilizer extending outwardly from the superior body surface, the superior stabilizer being characterized by a superior stabilizer surface; and an inferior stabilizer extending outwardly from the inferior body surface, the inferior stabilizer being characterized by an inferior stabilizer surface; wherein (i) the superior body surface and the inferior body surface are tapered relative to one another, and/or (ii) the superior stabilizer surface and the inferior stabilizer surface are tapered relative to one another.

An expandable prosthetic implant for engagement between vertebrae includes a first member having a first end, a second end, a plurality of extensions and a hollow interior portion extending from the first end to the second end, wherein the plurality of extensions extend from the first end to the second end. A second member includes a first end, a second end, a hollow interior portion extending from the first end to the second end, and a plurality of extensions extending from the second end to the first end. The plurality extensions of the first member are configured to coaxially interdigitate with the second member, and the plurality of extensions of the second member are configured to coaxially interdigitate with the first member. The first member of the implant is moveable relative to the second member along a longitudinal axis.

The present disclosure includes implant systems, devices, and implants. The interbody spacers including a first endplate, a second endplate, and a coupling member coupled to and extending between the first endplate and the second endplate. Methods of using the interbody spacers are also disclosed.
