Abstract: An expandable implant system is disclosed in which the system comprises an implant with: (1) top and bottom plates, (2) ramp surfaces formed on inner surfaces of the plates, and (3) an expansion member situated between the plates. An actuator also forms part of the system, the actuator being removable from between the top and bottom plates after implantation of the implant. The expansion member has a set of angled surfaces for mating with the ramp surfaces of the plates and, upon movement of the expansion member along a longitudinal axis of the implant, the top and bottom plates expand from a first dimension to a second greater dimension. The top and bottom plates are also securable at varying angles to one another depending on the amount of movement of the expansion member along the ramp surfaces.

Abstract: A joint spacer therapeutically maintains separation of bones of a joint. A carriage is slideably retained within the frame and has at least one ramped surface. An actuator screw is threadably engaged with the frame, and rotatably connected to the carriage, to cause the carriage to slideably move within the frame when the actuator screw is rotated. First and second endplates engage the bones of the joint, and each has at least one ramped surface that is mateable with the ramped surface of the carriage, whereby when the carriage is slideably moved by rotation of the actuator screw, the endplates ramped surface slides against the carriage ramped surface to cause the endplates to move along an axis transverse to the longitudinal axis of the frame, to increase the height of the spacer. Piercing elements are connected to the carriage to pierce bone of the joint when the carriage is moved.

Abstract: An instrument for establishing orientation of a pelvic prosthesis comprises a tripod having an angularly adjustable guide rod on it. The tips of the legs define a plane, and the guide rod is set by the surgeon to a defined orientation with respect to this plane on the basis of preoperative studies. In use, two of the legs of the instrument are positioned by the surgeon at defined anatomical locations on the pelvis (e.g., a point in the region of the posterior/inferior acetabulum and a point on the anterior superior iliac spine). The third leg then lands on the pelvis at a point determined by the position of the first two points, as well as by the separations between the third leg and the other two legs. The position of the guide rod then defines with respect to the actual pelvis the direction for insertion of a prosthesis.

An axial guide at a patient-specific position and orientation to guide a tool to perform an ACL/PCL reconstructive procedure according to a preoperative plan for the patient.

Abstract: An expandable implant for treating bone preferably in a minimally invasive manner includes a preferably cylindrical core element extending along a longitudinal axis and preferably a plurality of nestable, expandable sleeves extending along a longitudinal axis for placement radially about the core element. The plurality of nestable sleeves are sequentially insertable over the core element in such a manner that a first nestable sleeve is inserted over the core element and each subsequently inserted nestable sleeve is received between the core element and the previously inserted nestable sleeve such that the insertion of each additional sleeve causes each previously inserted sleeve to outwardly expand.

Abstract: A bone plate is formed with a throughgoing hole formed with a radially inwardly open outer groove. A screw fastener has a shaft engageable coaxially through the hole and a head of larger diameter than the shaft and adapted to bear axially on the plate around the hole. The shaft is formed offset from the head with a radially outwardly projecting ridge defining a radially outwardly open inner groove aligned radially with the outer groove when the fastener is fitted through the hole with the head bearing on the plate. An elastically deformable ring of a diameter generally equal to that of the hole at the outer groove is formed with at least one radially inwardly directed projection that, when the ring is fitted to the outer groove and the fastener is seated in the hole, projects radially inward into the inner groove of the fastener.

A method of assisting with attachment of a stock prosthetic implant to a patient tissue is also provided.

Abstract: 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.
