Hinged fixation devices for combined upper jaw correction
Instrumentation and methods are provided for upper jaw correction surgery. The application discloses an orthopedic system and method that can be used to perform both a first distraction (for example a maxillary distraction) and a second distraction (for example a maxillary expansion) within the same surgical procedure. The instrumentation for separating first and second bone segments can include a first footplate; a second footplate; an actuator arranged to vary a distance between the first and second footplates; and a hinge that rotatably attaches the first and second footplates such that the first and second footplates can be angularly adjusted relative to each other about a pivot axis. Additionally, instrumentation and methods are provided for a hinged fixation device capable of securing and adjusting both the linear separation and angular orientation of bone structures.
Implant insertion tool
A tool for inserting a spinal implant is disclosed. The tool includes a tube with a handle end, an inserter end having an opening, and a curved portion located between the handle end and the inserter end. A driveshaft with an actuator extends within the tube so that the actuator is proximate to the opening. A knob is attached to the handle end and the driveshaft, wherein turning the knob rotates the actuator. Methods of utilizing the tool, as well as variations of the tool are also disclosed.
Extra joint stabilization construct
The disclosure provides devices and methods of use pertaining to extra joint stabilization. Embodiments include a number of suture returning and locking anchors that feature both a suture return element and a suture locking feature that employs an interference fit between a flexible synthetic strand, a receiver of the anchor, and a set screw, where the receiver and the set screw each have a number of gradual, opposing tapers to facilitate gradual proximal-to-distal gripping and releasing of the flexible strand to achieve an optimal locking force while preventing severing of the flexible strand. Embodiments also include a counter-torque anchor driver configured to resist torsional forces generated during and translated to the anchor during set-screw insertion. Further embodiments include extra joint reinforcement, stabilization, and attachment constructs formed using the disclosed devices. Other embodiments are disclosed.
Compression and tension instruments and methods of use to reinforce ligaments
The disclosure provides apparatus and methods of use pertaining to syndesmosis reinforcement. Embodiments include a clamp having two jaws that extend toward each other to clamp two bone portions therebetween. The clamp may include an angle gauge and an adjustment mechanism having a force gauge that combine to enable the compression of the two bone portions in an optimal direction or angle and at an optimal, measurable compression force. Embodiments also include a tension instrument configured to knotlessly lock a flexible strand construct between two anchors at the same optimal direction and tension applied by the clamp. Further embodiments include an exemplary syndesmosis reinforcement procedure that employs the clamp and the tension instrument to construct a ligament reinforcement construct that achieves optimal anatomic positioning in both directional alignment and the reduction force applied by the construct. Other embodiments are disclosed.
ROBOTIC SURGERY
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.

Devices And Methods For Preparation Of Vertebral Members
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.
Intramedullary implant and method of use
A bone implant includes a proximal end, a distal end, a first portion extending between the proximal and distal ends having a maximum and minimum portion height, and a second portion extending between the proximal and distal ends having a maximum and minimum portion height. The second portion is connected to the first portion at the proximal end and the distal end and at least one of the first portion and the second portion is moveable relative to the other of the first portion and the second portion so as to transition the bone implant between a relaxed state wherein the first and second portions are separated by a first distance and a contracted state wherein the first and second portions are separated by a second distance different from the first distance. At least one of the proximal end and the distal end have the minimum portion height.
Surgical Staple Implant Kit
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.
INFLATABLE BONE TAMP WITH FLOW CONTROL AND METHODS OF USE
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.
