Abstract: A magazine supporting multiple bone grafts in chambers is coupled to a housing including a barrel. A plunger selectively passes through one of the chambers and along the barrel. A trigger mechanism advances the plunger along the barrel. A selector knob is movable into a plurality of positions, wherein each position employs one of a plurality of stops. One stop prevents the end of plunger from advancing past a predetermined ready position short of the end of the barrel when selected. Another stop prevents the plunger from advancing past a predetermined dispensing position substantially aligned with the end of the barrel when selected. Another stop prevents the plunger from advancing past a predetermined manipulating position beyond the end of the barrel when selected. In the manipulating position, the distal end of the plunger can be used to reposition the bone graft within the spinal disc cavity. Related methods are also provided.

Abstract: Implantable pliable bone blocks comprising a solid block of cortical bone characterized by a length, width and thickness, having a first and a second face on opposite sides of the block. The first and second faces have a plurality slot features. The angle of incidence of the slot features of the first face and the x-axis and the angle of incidence of the slot features of the second face and the x-axis (a2) are such that the slots would intersect if they were in the same plane. Methods are provided for making implantable pliable bone blocks.

Abstract: The present teachings provide one or more surgical implements for repairing damaged tissue, such as in the case of a spinal fixation procedure. A uniplanar bone anchor system for a fixation procedure is provided. The system can include a bone fastener including a head with a bearing surface and a shaft adapted to engage an anatomy. The system can also include a saddle, which can include a first bore formed about a longitudinal axis that receives the bone fastener and a coupling bore defined transverse to the longitudinal axis. The system can also include a coupling system, which can have a second bearing surface. The coupling system can be received through the coupling bore such that the second bearing surface of the coupling system can contact the bearing surface to permit the bone fastener to move in only one plane.

Abstract: An expandable spinal implant device for supporting vertebral bodies can include first and second body members and first and second expansion mechanisms. The body members can each have a first end positionable toward one of the vertebral bodies and can each define a hollow interior. The expansion mechanisms can be spaced apart from each other and can include a first drive shaft and a second drive shaft, respectively. The first and second drive shafts can each have a gear member fixedly coupled thereto. Each drive shaft can be threadably engaged at a first side to the first body member and at a second side to the second body member. The expansion mechanisms can be operable to effect axial displacement of the first body member relative to the second body member by rotationally driving the gear members of the first and second drive shafts.

Abstract: A dual reconstructive wire system for use with an anatomy can include a first guide wire, a second guide wire, a first guide instrument, a first cannulated insertion instrument, and a second cannulated insertion instrument. The first guide wire can pass through the first cannulated insertion instrument such that a first end and a second end of the first guide wire extends beyond the first end and the second end, respectively of the first cannulated insertion instrument. The second guide wire can pass through the second cannulation insertion instrument such that a first end and a second end of the second guide wire extends beyond the first end and the second end, respectively of the second cannulated insertion instrument.

Abstract: The present teachings provide one or more surgical implements for repairing damaged tissue, such as in the case of spinal stenosis. An implant for insertion between adjacent spinous processes is provided. The implant can include a body having a first end, a second end and defining a bore. The implant can include a first cap coupled to the first end of the body, a second cap coupled to the second end of the body, with each of the caps defining a space. The implant can include a connector coupled to the first cap and the second cap through the bore. The implant can include at least one deployable member coupled to the first end of the body and the first cap. The at least one deployable member can be retained within the first space in a first position, and can extend from the first space in a second position.

Abstract: A device for insertion between spinous processes of adjacent vertebrae is provided and may include a rod having a first threaded portion and a second threaded portion. The first threaded portion may be coupled to the second threaded portion at a joint. A plurality of members may be movable between a compressed condition and an extended condition when the rod is rotated relative to the plurality of members. The first threaded portion and the second threaded portion may be uncoupled at the joint after the plurality of members are moved from the extended condition to the compressed condition.
