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.

An implant is disclosed that has a base member, an articulating member, and a coupling portion that secures the base member to the articulating member. The implant can be a shoulder implant (100, 200, 300) that has a baseplate (102, 230, 310), an articulating component (104, 210), and a fixation component (106, 270, 342). The baseplate includes a first side (110, 234, 314) with a projection (108, 240, 320) that has a first Morse taper and may be offset from a center line of the baseplate and a second side (116, 236, 316) that has a post or stem (114, 250, 330) that is offset from the center line of the baseplate. The articulating component includes a cavity (122, 220) with a second Morse taper that is offset from a center line of the articulating component. The articulating component is attachable to the baseplate when the projection is received in the cavity of the articulation component. A threaded through hole (130, 222) extends from the cavity of the articulating component to a second, convex side or articulating surface (120, 212) thereof. The through hole can be aligned with the cavity. The fixation component (106, 270, 342) can engage the through hole and is contained within a cavity (132, 322, 242) of the baseplate by a spring (138, 262, 360) and a cap (140), a second fixation member (280), or an engagement member (370).

The present disclosure provides a bone-implantable device and methods of use. The bone-implantable device comprises a body having an exterior surface, wherein a portion of the exterior surface includes a cured osteostimulative material comprising MgO.

This disclosure relates to intervertebral disc prostheses which may have an upper plate, a lower plate, and a mobile core, with the upper surface of the core being in contact with at least a part of the lower surface of the upper plate. In some configurations, limit stops reduce friction while limiting or preventing the movements of the core relative to the lower plate, in translation and in rotation, respectively, along an axis substantially parallel to the lower plate and about an axis substantially perpendicular to the lower plate. Instrumentation for insertion of the prostheses into intervertebral spaces is also described.

A surgical implant with recesses adapted to capture fixation medium that extravasates during implantation. The implant includes an elongated stem having a distal tip configured for insertion into an implant receiving area of a patient. A collar having recesses for capturing extravasating fixation medium is attached on the stem. The collar can be fixed to the stem by a separable collar-engagement feature or the collar can be fixed to the stem via structures on the stem.

The present invention refers to an osteochondral local prosthetic insert for partial humeral joint reconstitution by reconstitution of the bone anatomical sphericity to treat bone lesions, in particular Hill-Sachs lesions. The local osteochondral prosthetic insert is a rigid monolithic body having a truncated-cone shape, the proximal diameter greater than the distal diameter, the proximal end of convex shape and rounded at the corners, and a tapered distal end. The lateral surface of the insert shows in the middle-distal part a non-return shaping that allows the maintenance of the position defined in the surgical operation. The proximal end is convex in order to better adapt to the local bone sphericity and has recesses for the manipulation and positioning through dedicated tools.

Embodiments of a composite interbody system 10 for treating mammalian bony segments including various materials to encourage bony fusion while enabling radiographic visualization where the composite interbody system 10 may be employed between two, adjacent mammalian bony segments to stabilize, maintain spacing between, or couple the bony segments. Other embodiments may be described and claimed.

Disclosed herein are an implant with a suture passage and a method of attaching sutures to the same. The implant may include a suture pocket having a first pocket, a second pocket, and a suture hole disposed therebetween. The first pocket may have a first wall segment, the second pocket may have a second wall segment, and the suture hole may have a first sidewall segment extending from a first opening to a second opening. The first wall segment, the second wall segment, and the first sidewall segment may form a contiguous wall. A method of attaching a suture to the implant may include placing a tip of a suture needle on the first wall segment, sliding the suture needle into the first opening and pushing the suture needle through the suture hole.

A four-component artificial intervertebral disc may provide six degrees of movement: flexion, extension, lateral bending, axial rotation, axial deflection, and anterior/posterior translation. The disc may include a superior endplate, a superior core, an inferior core, and an inferior endplate. The superior endplate may include a concave mating surface, and the inferior endplate may include a spherical mating surface. The superior endplate may roll across the superior core to provide flexion, extension, and lateral bending. The superior endplate may twist or rotate atop the superior core to provide axial rotation, and the superior endplate may slide over the superior core to provide anterior/posterior translation. The superior core may be connected to the inferior core, and the inferior core may be connected to the inferior endplate. The inferior core may be made from a flexible material that may enable the artificial disc to expand or compress vertically.

A surgical implant with recesses adapted to capture fixation medium that extravazates during implantation. The implant includes an elongated stem having a distal tip configured for insertion into an implant receiving area of a patient. A collar designed to house recesses for capturing extravazating fixation medium is attached on the stem. The collar can be fixed to the stem by a separable collar-engagement feature or the collar can be fixed to the stem via structures on the stem.
