Abstract: A reduction sleeve for facilitating insertion of a spinal rod into a rod-receiving channel formed in a bone fixation element. The reduction sleeve may include a through-bore sized and configured to receive the bone fixation element and a substantially transverse channel sized and configured to receive the spinal rod. The channel being substantially aligned with the rod-receiving channel formed in the bone fixation element so that, once the bone fixation element has been inserted into the reduction sleeve, the spinal rod can pass through the aligned channels. The reduction sleeve may also include at least one break-off point or region for facilitating breaking and removal of the reduction sleeve once the spinal rod has been clamped into the rod-receiving channel of the bone fixation element.

Abstract: A minimally invasive fixation system and method for providing access to a surgical site. The fixation system may include a holding assembly, the holding assembling preferably including a lateral implant holder which may be attached to a pedicle screw and a sleeve positioned in connection with the lateral implant holder to prevent the lateral implant holder from separating from the pedicle screw. The sleeve may further include a tissue protection portion to keep the tissue out of the surgical site. A holding sleeve may be operably connected to the holding assembly and pedicle screw and may be used to insert the pedicle screw into the body. Multiple constructs may be inserted into the body so that a portion of the holding assembly extends from the body and provides access to and visualization of the surgical site. A rod holder may also be used to insert a rod into the head of the screw. The rod may be held by the rod holder so that the rod may be angulated as the rod is inserted into the screw heads.

Abstract: A fixation system includes a plate comprising a top surface, a bottom surface, a central longitudinal axis, at least one fixation hole extending between the top and bottom surfaces and comprising an undercut therein, and at least one passage intersecting one of the undercuts. At least one resilient clip is disposed in at least a portion of the undercut, with the at least one clip having a pair of generally parallel sides and an end tab. At least one fastener is provided and comprises a head and a threaded shaft, with the head comprising a perimetral groove extending around at least a portion thereof and an instrument receiving portion. The at least one clip is configured and dimensioned to seat in the undercut with the end tab extending within the passage, and the at least one fastener is configured and dimensioned to be received in the at least one fixation hole and securable therein when the at least one clip abuts the perimetral groove of the head.

Abstract: Spinal rod reduction apparatuses, systems, and methods are provided. In various examples, a rod reduction apparatus includes a first threaded member including an engagement feature configured to selectively anchor the first threaded member to the implantable screw assembly. A second threaded member is configured to threadably engage with the first threaded member. The second threaded member is axially movable with respect to the first threaded member with rotation of the second threaded member. A spinal rod urging member is axially movable with the second threaded member. The urging member includes a bearing surface that is configured to selectively abut the spinal rod and selectively urge the spinal rod toward the implantable screw assembly with rotation of the second threaded member in a first rotational direction.

Abstract: A transconnector for use in interconnecting a pair of longitudinal spinal rods in a spinal fixation procedure. The transconnector includes a bridge member and first and second spinal rod engaging members. The bridge member may include first and second members, wherein the first and second members are moveably associated with one another so that the distance between the first and second spinal rod engaging members can be adjusted. The first and second spinal rod engaging members include a rod receiving channel for receiving one of the spinal rods therein. The spinal rod engaging members may be articulating in, for example, the yaw and roll positions or non-articulating with respect to the bridge members. The spinal rod engaging members preferably include a spring, for example, a spring washer, to provide an opposing force so that the spinal rod engaging members can provisionally snap onto the spinal rods.

Abstract: A cage for implanting in bone that has a first plate having a surface that contacts a first bone surface, a second plate having a surface that contacts a second bone surface, a intermediary plate that dynamically couples to the first plate and the second plate, an actuator that drives and causes the intermediary plate to move between the first plate and the second plate along a predetermined direction, and an anchor that attaches to the first plate and the second plate to engage the actuator to drive the actuator longitudinally along the predetermined direction.

Abstract: A cage for implanting in bone includes a main body having a fastener mounting receiver. The main body includes a first surface that contacts a first bone surface, a second surface that contacts a second bone surface, a side wall extending between the first and second surfaces, and a front wall comprising a connection surface, wherein the fastener mounting receiver extends from the connection surface. A fastener is placed within the fastener mounting received and configured to engage and fix a plating device on the connection surface of the main body.

Abstract: Translational bone fixation assemblies, kits containing such assemblies, and methods of use are described herein. The described assemblies may be used in spinal fusion procedures in which a damaged or diseased disc (or part of a disc) is removed from between a pair of vertebrae and a spinal fusion spacer is placed between the vertebrae. The assemblies may be applied to an anterior portion of the affected vertebrae to span the affected disc space, and may be fixed to the vertebrae using bone screws. The assemblies may function to maintain the vertebrae aligned during the initial period following fixation in which fusion of the spacer to the adjacent vertebrae occurs. The assemblies may also function to share some of the axial spinal load applied to the fusion spacer to prevent extreme subsidence of the spacer into the vertebral body, such as where the patient has poor bone quality.
