A tool for delivery and/or compaction of bone graft material includes a cannula with an inner lumen extending along a longitudinal axis from a hopper end of the cannula to a delivery tip of the cannula. A hopper with an internal volume for storing bone graft material is connected to the hopper end of the cannula with the internal volume of the hopper in communication with the inner lumen of the cannula for delivery of bone graft material from the hopper to the delivery tip of the cannula. An output shaft within the inner lumen extends along the longitudinal axis. The output shaft includes a helical screw thread extending radially outward from the output shaft toward an inner surface of the cannula. An actuator is connected to the hopper and to the output shaft to drive the output shaft rotationally relative to the hopper and to the cannula.

The present invention relates to a series of orthopedic plates for use in repair of a bone. The plate has a Y-shaped profile or an X-shaped profile which includes an elongate central trunk with a complex contour and either one or two terminal pairs of arms that have a first arm and a second arm that form differing angles and lengths relative to the trunk portion of the plate. The arms include locking screw holes where the screws converge toward each other to provide for multiplanar fixation but which do not impinge.

Devices and methods for preparing a surgical site, and in particular vertebral members, which may include a retractable tool and an actuator. The tool may include distal and proximal members. A distal side of the distal member may be fixed in a longitudinal direction and pivotable at a point of rotation. A proximal side of the proximal member may be pivotably connected to the actuator. In a retracted position, the distal member may be pivotably connected to the proximal member longitudinally in between the point of rotation and the proximal side of the proximal member. Moving the actuator in a distal direction may push the proximal member and the distal member such that the proximal member pivots with respect to the actuator and distal member, the distal member pivots with respect to the proximal member and point of rotation, and the proximal member and distal member move laterally outward.

Apparatus and methods for distracting and/or compressing bone. An exemplary apparatus may comprise a rod having a thread. The apparatus also may comprise a first assembly and a second assembly each coupled, or configured to be coupled, to the rod and each configured to be attached to a respective pin extending into bone. The apparatus further may comprise a nut engaged, or configured to be engaged, with the thread and configured to be turned to drive the second assembly along the rod. In some embodiments, at least one of the assemblies may have at least two degrees of rotational freedom that can be eliminated by manipulating a single graspable member. In some embodiments, the rod and the second assembly may have anti-rotation features configured to interact with one another to permit travel of the second assembly along the rod while preventing rotation of the second assembly about the rod.

An apparatus and a method are provided for a sterile staple implant kit that a surgeon may unpack and utilize during a surgery. The staple implant kit comprises a group of complementary surgery-specific instruments that are packaged in a sterile state. An instrument tray is configured to preserve the instruments in the sterile state until the staple implant kit is opened during the surgery. The instrument tray is configured to provide the surgeon with easy access to the instruments during the surgery. The staple implant kit comprises at least a staple inserter and a surgical staple suitable for being implanted in parallel holes drilled across a bone fusion or fixation site of a patient. The surgical staple preferably is loaded in a relaxed configuration into the staple inserter. A staple retention clip retains the surgical staple in the staple inserter until the staple is distracted during the surgery.

An inflatable bone tamp is provided that includes a shaft with proximal and distal portions and a central longitudinal axis. A balloon is attached to the shaft such that a material can flow through the shaft and into the balloon to inflate the balloon. A flow controller controls the flow of the material through the shaft and into the balloon. Kits, systems and methods are disclosed.

A method of using a robotic guidance system for performing surgery on a spine is provided. The method includes utilizing a computerized tomographic scan image of a location on a spinal column of a patient, such that the computerized tomographic scan image is connected to a computer and visible on a monitor connected to the computer. The method also includes attaching a coupling component to the spinal column of the patient, coupling a marker to the coupling component, and imaging, with a fluoroscope, the view of the spinal column of the patient, wherein the fluoroscope image is transmitted to the computer and visible on the monitor and the at marker is clearly visible in the fluoroscope image. The method also includes positioning a cannula, with a robotic mechanism, to a first position relative to a vertebra in the spinal column of the patient, drilling a passage through the cannula into bone of the vertebra in the spinal column of the patient, inserting a guidewire through the cannula into the passage in the bone of the vertebra in the spinal column of the patient, and positioning a screw into the bone of the vertebra in the spinal column of the patient.
