The present invention provides a negative pressure guided bone cement injection systme comprising a negative pressure system, comprising a negative pressure introduction device, a pushing system for implant bone cement to the target area, a control systmem for regulating the negative pressure system and the pushing system, and at least one sensing device disposed at any position of the negative pressure system, which can sense at least one environmental paramtere for observing the physiological condition of a patient's spinal vertebral body can be monitored immediately, and the result is actively or passively sent back to the system or the operator for adjusting the injection parameters.

A bone fastener includes a shaft. The shaft includes a wall that defines a longitudinal cavity and a plurality of openings in communication therewith. The openings are disposed in axial alignment along the shaft and the wall is closed exclusive of the openings. In some embodiments, systems, spinal constructs, surgical instruments and methods are disclosed.

An all-in-one odontoid fracture repair apparatus, system, and method may include an odontoid guide comprising an odontoid guide cannula having a proximal end, a distal end, and a first longitudinal passage extending through the odontoid guide cannula between the proximal and distal ends of the odontoid guide. The odontoid guide may include a vertebra coupler located at the distal end of the odontoid guide cannula that may be configured to couple to a first vertebra of a patient. The odontoid guide may be configured to receive bone cement within the first longitudinal passage of the odontoid guide cannula and deliver the bone cement through the first longitudinal passage of the odontoid guide cannula to an odontoid process of the patient in order to repair a fractured or osteoporotic odontoid process in the ever increasing fragile geriatric population.

An implant filling apparatus may include an actuator mechanism, a push rod, straight fill tubes and/or diverted tip fill tubes and an implant connector. An actuator impacts the push rod at a predetermined pressure and rate such that the push rod can drives fill material out of the fill tube(s) and into an implant that is coupled to the implant connector.

A central inflatable distractor and a perimeter balloon are inserted into the disc space in uninflated configurations. The central inflatable distractor is then expanded, thereby distracting the vertebral endplates to the controlled height of the central inflatable distractor. The perimeter balloon is then inflated with a curable substance. The perimeter balloon expands as it is filled with the curable substance and conforms to the void remaining in the disc space around the central inflatable distractor, thereby creating a horseshoe shape. Once the flowable material in the perimeter balloon has cured, the central inflated distractor can be deflated and removed. The remaining void (or inner space) is then packed with graft for fusion.

A device for correcting a compression-type fracture including a housing at a proximal end of the device, a cannula extending from the housing and through a directional balloon, and a tip at a distal end of the cannula, wherein the cannula has an outer tube for supplying fluid to the balloon and an inner tube positioned within the outer tube for supplying cement through at least one opening in the distal end of the cannula. A method of using the device where the device is inserted into a fracture site, the balloon is inflated to elevate fragments of the fracture, cement is injected into the opening created by elevating the fragments of the fracture and the device is removed from the fracture site. The balloon may be deflated before the injection of the cement or simultaneous with the injection of the cement.

A kyphoplasty system includes various instruments which can be selectively used in a surgical theater (e.g., during a surgical operation on a patient) or a surgical training environment. The kyphoplasty system can include one or more of a kyphoplasty apparatus, a prone table mat, a connector system, a bone introducer needle, and a biopsy device. The kyphoplasty system may also include a training system for use in the training environment.

A surgical system includes a sleeve defining a passageway. An adapter is removably coupled to the sleeve. The adapter defines a channel. A delivery device includes a distal end positioned in a channel of the adapter. A bone fastener includes a head and a shank defining a cannula. A distal portion of the adapter is positioned in the shank such that the channel is in communication with a cannula of the shank. A plunger is movably disposed in a lumen of the delivery device. The plunger is configured to move a material through the lumen and the channel and into the cannula. Methods and kits are disclosed.

Attachment devices and methods of using the same are disclosed. The attachment devices can be fenestrated. The fenestrations can control the flow of fluid out of and/or into the device.

A portable and passive safety intraosseous device to allow for direct introduction of medications, etc., within the intermedullary space of a subject patient's bone or, if needed, the removal of certain substances from such a subject patient's bone. Such a device permits direct drilling and placement of a cannula within the subject bone with access external to the subject patient's skin, permitting, as well, connection of a tube for such introduction/removal purposes. The ability to provide a passive safety unit allows for facilitated utilization in, for instance, emergency situations with the entire device provided for utilization thereof. The device includes a drilling component with a permanently attached stylet and a removable cannula, a power supply for a single drilling operation, a mechanism to draw the stylet back into the drill component after use and disengagement from the cannula, and an automatic closure that activates with the separation of the cannula.
