Abstract: Methods and devices are provided for anchoring graft to bone. In one exemplary embodiment, a bone cavity is created in bone, a graft is partially advanced into the bone cavity, and a hardenable filler material is inserted into the cavity. The hardenable filler material can change from a viscous first state to a harder second state, compressing the graft against the walls of the bone cavity and thereby anchoring the graft within the cavity. The hardenable filler material can be inserted in an open sac, a closed sac, other carriers or housings, or directly into the bone cavity.

Abstract: Devices, systems, and methods are provided for ligament repair procedures, and can be used to establish a location and trajectory for forming a bone tunnel in bone. One exemplary embodiment of a surgical guide for using in a ligament repair procedure includes a guide arm and a carriage that can be selectively locked along the guide arm to define an angle of the bone tunnel. The guide arm also defines a location of a distal end of the bone tunnel. In some embodiments the carriage is configured to have a bullet side-loaded into it, and the bullet can be used to define a location of a proximal end of the bone tunnel. The present disclosure also provides for a gage that limits the distance a drill pin that drills the bone tunnel can travel. A variety of other, devices, systems, and methods are also provided.

Abstract: Cutting instruments and related methods are disclosed herein in which the diameter of the retrograde cutting blade can be adjusted to any of a plurality of diameter settings, allowing the same instrument to be used to form holes of different diameters. The limit diameter can be preset such that, during the cutting operation, the user need not be concerned with selecting the appropriate diameter, but rather can simply deploy the cutting blade until the preset limit is reached. Cutting instruments are also disclosed in which the retrograde cutting blade is distinct from the forward drilling tip and protected within a cavity formed in the body of the instrument when not in use, as are instruments in which the user is given visual and/or tactile feedback to confirm desired positioning of the cutting blade.

Abstract: An instrument for manipulating a spinal fixation element relative to a bone anchor includes a bone anchor grasping mechanism, a first adjustment mechanism, and a second adjustment mechanism. The bone anchor grasping mechanism includes a first arm having a distal end configured to engage an opening provided in the bone anchor. The first adjustment mechanism includes a second arm pivotally connected to the first arm. The second arm has a distal end configured to engage an opening provided in the bone anchor and is operable to adjust a spinal fixation element in a first direction upon pivoting relative to the first arm. The second adjustment mechanism is removably and replaceably coupled to the bone anchor grasping mechanism and is movable relative to the bone anchor grasping mechanism to adjust the spinal fixation element in a second direction, perpendicular to the first direction, relative to the bone anchor.

Abstract: A screw placement guide tool for use in minimally invasive surgery has a proximal handle portion, an extension member extending distally from the handle portion, and an alignment element connected transversely to a distal portion of the extension member and having a screw placement guide located thereon. In this aspect of the invention, the tool is configured so that a surgeon may operate the tool using the handle portion external to a patient's body to align the alignment element with implanted screws so that the screw placement guide indicates a desired position for implantation of an additional screw. Systems and methods for placing a rod receiving screw are also provided.

Abstract: An instrument for engaging a bone anchor may include a first implant engaging member having a proximal end and a distal end and a second implant engaging member having a proximal end and a distal end. The second implant engaging member may be integrally connected to the first implant engaging member by a pair of opposed integral spring members located proximal to the distal ends of the first and second implant engaging members. Manipulation of the proximal ends of the first and second implant engaging member can cause each of the distal ends to rotate about the pair of opposed spring members to engage at least a portion of a bone anchor. A rod adjusting tool may be connectable to the bone anchor engaging tool and may be axially adjustable relative to the bone anchor tool to adjust a spinal rod relative to the bone anchor.

Abstract: The present invention provides methods and devices for reducing a rod disposed within or adjacent to a rod-receiving head of a spinal implant. In general, a rod reduction device is provided that can removably mate to the rod-receiving head of a spinal implant and be effective to reduce a rod disposed within or adjacent to the rod-receiving head. In an exemplary embodiment, the rod reduction device can include a clamping member that is adapted to removably mate to a rod-receiving head of a spinal implant and a rod-reducing arm that is rotatably matable to the clamping member. The rod-reducing arm can be configured such that rotation of the arm with respect to the clamping member is effective to reduce a rod into the rod-receiving head of the spinal implant that is mated to the clamping member.

Abstract: A compressor tool for use in minimally invasive surgery is provided having first and second elongate elements where each elongate element is connected to the other at a pivot point within a pivot region of each element for rotating articulation in an articulation plane with respect to each other. The first and second elongate elements are configured to provide a tool pivot region including the pivot point, a tool handle proximal to the tool pivot region, and a tool working portion distal to the too pivot region so that pressure applied to the tool handle portion results in a compressive force being applied by the tool working portion. The tool has a first closed position for insertion of the tool through an incision or portal so that the pivot region is located within the incision or portal, and a second working position where the tool working portion is arranged to provide a compressive force to spaced apart elements within a patient's body.

Abstract: An implant holder is provided having first and second gripping arms, each having a proximal portion with a mating element formed thereon for selectively mating to a medical device, and a distal portion adapted to at least partially circumferentially engage and axially align with a rod-receiving member, e.g., a head, of a spinal implant. The spinal implant holder further includes an actuator mechanism coupled to the first and second gripping arms and effective to move the gripping arms between an open position, in which the gripping arms can be positioned around the rod-receiving head of a spinal implant, and a closed position, in which the gripping arms engage the rod-receiving head of the spinal implant. A rod reduction device is also provided and includes an elongate inserter tool having a proximal end and a distal end with a fastener-retaining member formed thereon and adapted to retain a fastener therein.
