The base plate includes a bone facing side, an implant side opposite the bone facing side, a curvate perimeter, at least one fin protruding from the bone facing side a first distance and extending linearly a length along the bone facing side, and an implant engagement structure on the implant side. The humeral head implant includes a curvate implant surface and a base plate engagement structure opposite the curvate implant surface, the base plate engagement structure configured to couple to the implant engagement structure of the base plate.

An interbody spinal implant including a body portion having a superior side, an inferior side and a lateral side connecting the superior side and the inferior side, at least one of the superior side or the inferior side comprises a bone contacting surface operable to be coupled to an anatomical structure of a patient; and a plurality of uniform features formed in the bone contacting surface, wherein each uniform feature of the plurality of uniform features comprise a planar peak or a round peak and are dimensioned to increase a surface area of the bone contacting surface to promote bone growth.

This disclosure presents various embodiments of a transforaminal intersomatic cage for an intervertebral fusion graft, and an instrument and method for implanting the cage, an embodiment of the cage having a body in the shape of a circular arc and comprising a lateral concave surface, a lateral convex surface, a straight upper surface, a straight lower surface and an end wall having at least one hole, called the end hole, designed to receive a rod of an instrument for implanting the cage between the vertebrae, wherein: the end hole has an orientation that is more or less tangential to the circular arc described by the body; the extremity opposite to the end wall of the body includes a return part extending the body toward the center of the circle on which the circular arc described by the body lies.

The disclosure relates to a replacement member for a shoulder joint replacement comprising an attachment face on one side of the member, a concave joint surface on a side of the replacement member opposite to the side of the attachment face, and a circumferential face connecting the attachment face and the joint surface. A portion of the concave joint surface is connected to at least a portion of the circumferential face via a chamfered or rounded edge.

An orthopaedic implant includes: a base including a molding material; a first porous ingrowth material region coupled to the base; a second porous ingrowth material region coupled to the base; and at least one barrier insert coupled to the base, the barrier insert including a barrier material that is configured to prevent introduction of the molding material of the base into some pores of the first porous ingrowth material region and some pores of the second porous ingrowth material region during molding of the base.

A knee prosthesis (e.g., a tibial implant or component) is disclosed. In one embodiment, the tibial implant includes a load bearing component (e.g., a tibial tray) and a support member arranged and configured to be at least partially positioned within an intramedullary canal of a patient's bone. In some embodiments, the tibial implant may also include one or more pegs positioned anteriorly on a bottom surface of the tray and one or more bridges for coupling the pegs to the support member so that loads received by the pegs are transferred to the support member via the bridge. In addition, and/or alternatively, the tibial implant may include one or more chamfers or loading zones for elongating the transition area between the support member and the bottom surface of the tibial tray to extend the area over which the load is transferred.

Hard-tissue implants are provided that include a bulk implant, a face, pillars, slots, and at least one support member. The pillars are for contacting a hard tissue. The slots are to be occupied by the hard tissue. The at least one support member is for contacting the hard tissue. The hard-tissue implant has a Young's modulus of elasticity of at least 3 GPa, and has a ratio of the sum of (i) the volumes of the slots to (ii) the sum of the volumes of the pillars and the volumes of the slots of 0.40:1 to 0.90:1. Methods of making and using hard-tissue implants are also provided.

The present disclosure relates to an artificial ankle joint tibial component and, more particularly, to an artificial ankle joint tibial component of an implant that is implanted into a body, the implant including: a body part having a contact surface in contact with a resected surface of a distal end of a tibia of a joint and a joint surface facing a joint; and a fixing part formed to extend a predetermined length upwards from the contact surface, wherein the fixing part is configured as a single body formed to extent a predetermined length upwards from the center in the front area of the contact surface and includes a wing extending to one side, and wherein the wing includes at least one posterior wing that extends at a predetermined angle relative to an AP line, thereby preventing stress from being concentrated on one wing to avoid a fracture thereof and increasing the contact area between a bone and an implant to strengthen fixing force, prevent rotation, and disperse stress, so that bone resorption around the wing can be prevented.

The present invention provides cervical implant (30) comprising an upper surface (38), a lower surface (40), a posterior portion (34) and an anterior portion (36) and including a perimeter (42) and one or more apertures (44,46) within said anterior portion for receiving securing means, said apertures having respective longitudinal axes M1, M2, characterised in that said axes extend in a direction substantially through said anterior portion (36) and converge at a point in a plane outside of said perimeter (42).

A partial ankle prosthesis includes a tibial component including a superior surface configured to be attached to a lower end of a patient's tibia; a poly component that is fixedly attached to the tibial component and includes a concave inferior surface of an anti-friction material; and a talar component including an inferior surface configured to be attached to a patient's talus and a single convex superior surface configured to mate with the inferior surface of the poly component; and the partial ankle prosthesis is configured to be implanted in a single compartment of a patient's ankle.
