The present application is generally directed to implantable systems, devices and related methods pertaining to spinal surgery. In particular, the present application discloses a frame and spacer system for inserting into a disc space. The frame and spacer system is of low profile. The frame can receive different fixation devices, including threaded and non-threaded fixation devices.

Unicompartmental tibial components are described herein. A first unicompartmental component (10) comprises a plate (12) having a bearing surface (18) and an opposing surface (22) that is configured to be secured to a proximal end of a patient's tibia, wherein the plate further comprises an anterior end (24), an outer side (25), a posterior end (26) and an inner side (27), wherein a mediolateral width W of the plate is defined between the outer and inner sides, and a longitudinal anteroposterior axis (28) extends between the anterior and posterior ends approximately one third of the width of the plate (i.e. 1/3 W) from the lateral side, and defines a longitudinal axis length L of the plate. A first elongate peg (14) protrudes from the opposing surface in the anterior portion, the first elongate peg defining a first peg axis (32). A second elongate peg (16) protrudes from the opposing surface in the anterior portion, the second elongate peg defining a second peg axis (34). The first and second peg axes are disposed at an angle of 45-70 degrees with respect to the longitudinal anteroposterior axis and are substantially parallel to one another such that the first and second pegs protrude posteriorly as well as distally with respect to the plate. An anterior portion of the plate comprises a part of the plate defined by an anterior 60% or less of the longitudinal axis length L, whilst a posterior portion of the plate comprises a part of the plate that is defined by the remaining posterior 40% or more of the longitudinal axis length L. The posterior portion of the opposing surface is free from pegs or other fixation devices, and the first and second elongate pegs are located more than half of the mediolateral width W of the plate from an outer edge of the plate. The component is configured for cementless fixation using an interference fit. Also described is a method of installation and a tool suitable for use in installation.

The intervertebral implant is in the form of a three-dimensional structure (10) comprising (a) a top side (1) and an underside (2) which are designed to rest against the end plates of two adjacent vertebras, (b) a left side face (3) and a right side face (4), (c) a front face (5) and a rear face (6), (d) a horizontal center plane situated between the top side (1) and the underside (2), (e) a vertical center plane (8) situated between the left side face (3) and the right side face (8) and (f) a plurality of boreholes (9) passing through the implant structure (10) that are designed to receive longitudinal affixation elements (20), the axes (19) of said elements intersecting the horizontal center plane (7). At least one of the boreholes (9) is designed in a manner that the affixation element (10) received in it can be rigidly connected to the intervertebral implant. Said connection is implemented using a thread or by matching conical surfaces.

A method of making a spacer device or a device to be implanted in a human body that includes a containment body and is suitable for treating a bone seat or a joint seat of the human body includes a base portion and side walls that extend from the base portion and that delimit between them at least one cavity, wherein the containment body has a plurality of pores and/or at least one opening, configured to place the at least one internal cavity in communication with the outside of the containment body.

An interbody spinal fusion implant includes a tapered body and a faceplate secured to the tapered body. The faceplate has a recess formed on a front face of the faceplate that is at least partially bounded by an interior surface. A first screw hole and a spaced apart first locking slot pass through the faceplate, the first locking slot having an elongated width. A first locking screw has a head and a threaded shaft, the threaded shaft passing through the first locking slot and being sized so that the threaded shaft can slide laterally along a length of the elongated width of the first locking slot. A first nut is disposed between the tapered body and the faceplate, the shaft of the first locking screw being threadedly engaged with the first nut.

The present invention relates to a stabilized ankle prosthesis configured for use in patients with compromised soft tissue in the ankle. The prosthesis of the present invention is a two-component design comprising a stabilizing lip configured to constrain movement in the general direction of compromised soft tissue.

The invention relates to medical implants, including spinal implants and bone grafts, for fixation and integration with hard tissue. The bone medical implants include at least one rotational fixation mechanism that further includes or is attached to one or more sharp protrusions configured to penetrate and become lodged into hard tissue to provide support and positional stability. Such support is useful to ensure that the spinal bone graft may be used without additional stabilizing or anchoring structures, such as supporting plates or screws.

An implant system for implantation at a joint. The implant system includes an implant device with a body portion having first and second ends, and a first elongate member, extending from the first or second end of the body portion. The implant system has a corresponding fixation device with at least one latching element. The first elongate member has at least one cooperating element capable of cooperating with the at least one latching element of the fixation device in use.

The present disclosure relates to a 3D-printed semi-finished part for manufacturing at least one medical implant or medical instrument, the semi-finished part including: at least one functional feature provided at a predefined location of the semi-finished part.

A total elbow replacement prosthesis (100) comprising: a radioulnar component (20) having an ulnar bearing surface (22) and an anconeal process bearing surface (24), a humeral component (40) having a trochlear bearing surface (42), the trochlear bearing surface being configured for bearing against the ulnar bearing surface, the humeral component further comprising an olecranon aperture boundary bearing surface (50), the anconeal process bearing surface being configured for bearing against the olecranon aperture boundary bearing surface.
