The present invention relates to an implantable anterior cervical plate having a stackable superior design, which deflects soft tissue.

A plate and cage assembly for stabilization of vertebral bodies. The assembly includes at least one fixation member, a cage having a proximal wall, a superior surface and an inferior surface (the superior surface and the inferior surface for engaging adjacent vertebrae), and a plate coupled to the cage and having at least one hole traversing the plate at an angle for insertion of the at least one fixation member into one of the vertebral bodies. The proximal wall of the cage has a blind hole, and the plate has a threaded screw hole aligned with the blind hole in the proximal wall of the cage.

A stemless humeral head replacement system including a base plate and a humeral head implant. 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.

A tibial, prosthesis, and, particularly, a fixed bearing tibial, prosthesis has a two-pronged securement mechanism. The securement mechanism may or may not be angled. Advantageously, the securement mechanism, working alone or in cooperation with other securement features, minimizes micromotion between the tibial tray and tibial hearing component.

Systems and methods are described for correcting sagittal imbalance in a spine including instruments for performing the controlled release of the anterior longitudinal ligament through a lateral access corridor and hyper-lordotic lateral implants.

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.

Shapeable porous metal implants and methods for use in various procedures are disclosed. The implants can comprise a shell according to some examples. According to one example, the method can include providing a sheet of highly porous metal material having a porosity of between 55% and 90%, and wrapping the sheet of highly porous metal material around at least a first bone of the patient. Further examples can form the sheet intra-operatively to a desired shape. In an example, the porous metal sheet can be formed of tantalum or tantalum alloys.

An implant for insertion into a disc space between vertebrae, wherein the implant includes a spacer portion, a plate portion coupled to the spacer portion, two bone fixation elements for engaging the vertebrae and a retention mechanism for preventing the bone fixation elements from postoperatively backing-out of the plate portion. The retention mechanism may be in the form of a spring biased snapper element that is biased into communication with the bone fixation elements so that once the bone fixation element advances past the snapper element, the snapper element is biased back to its initial position in which the snapper element interfaces with the bone fixation elements. Alternatively, the retention mechanism may be in the form of a propeller rotatable between a first position in which the bone fixation elements are insertable to a second position where the bone fixation elements are prevented from backing-out.

Systems and methods are described for correcting sagittal imbalance in a spine including instruments for performing the controlled release of the anterior longitudinal ligament through a lateral access corridor and hyper-lordotic lateral implants.

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.
