A compression fastener system includes an elongate generally rigid coupling component, a toggle anchor at the distal end of the coupling component that can pivot about 90 degrees between inline and out of line with the coupling component, and a generally cylindrical collet that is engageable with a surface of the coupling component, and having two or more legs that splay upon passage of the coupling component through the collet, at least one leg having a cutting edge along at least a portion of its length that can engage with an adjacent rigid element, such as bone, to fix the rigid coupling component, toggle anchor and collet assembly into compression with the rigid element.

An apparatus for use in placing an implant into a patient is disclosed. The apparatus features an outer assembly having an outer shaft with an expandable driving member at its distal end and an inner canulated shaft that fits within and cooperates with the outer shaft to affect the driving member. The inner shaft includes an actuation knob attached to the proximal end of the inner shaft. A locking or driving thread is included on the outer surface of the inner shaft, proximal to the adjustment knob. The outer shaft includes a housing with the threaded interior such that when the inner shaft is mounted within the outer shaft, the driving thread operates with the threaded interior of the housing to allow for the inner shaft to be advanced along the inside of the outer shaft as the knob is turned. The tip of the inner shaft interacts with the interior of the driving member to expand the driving member.

A compression nut for treating a bone includes a head and a body extending longitudinally from the head to a free end. The body includes a first portion including an exterior surface tapering from the head toward a second portion. An exterior threading extends along an exterior surface of both the first portion and the second portion of the body. The nut also includes a channel extending longitudinally through the body. The channel includes an interior threaded extending along an interior surface of the channel configured to threadedly engage a portion of a locking screw therein.

A fracture treatment system can include a pair of implants cross-pinned into the medullary canal of a bone, guided by at least one guide wire with at least two diameters. The system allows for more accurate sizing of the length of implants needed to achieve bicortical purchase for enhanced stability, as well as anti-rotation of the fracture site. The more accurate sizing and placement of the cross-pinned implants additionally allow both ends of the implants to recess beneath or be flush with the outer surface of the bone, which can reduce the risk of infection. The guide wire can allow the implants to be inserted using a cannulated technique for easier surgical procedure and better outcome, with the implants having sufficient wall thickness for the desired length to achieve bicortical purchase while keeping the shaft outer diameter of the implant to be similar to a diameter of the guide wire.

One or more techniques and/or systems are disclosed for a tool driver device that can apply counter-torque to the device while applying torque to a target component that is engaging a target base. The example device can be operated by one hand to actuate a power input component that provides the desired torque, while providing counter-torque to offset rotation of the device. A selectably engaged counter-torque component is selected to complement the target base, to operably hold it in place during use. A power input provides power to apply rotational force to drive a selectably coupled tool, which has been selected to complement the target component engaged with a target base. The counter-torque component is operably engaged with the base, which applies counter-torque to the torque provided by the target component.

The present disclosure describes a device and methods for safely and accurately placing screws into bones with a powered driving device. By employing multiple layers of fail-safe features and image-guidance systems, the powered driving device provides safe, accurate, and efficient screw placement. That is, the powered driving device may continuously monitor a screw advancement and placement and may automatically shutdown when improper placement is detected. Monitoring placement may be conducted by a microcurrent-monitoring system, by an image-guidance system, or by any other appropriate sensory system. Additionally, upon detecting that screw insertion is complete, the powered driving device may be automatically shutdown. As screw placement is continuously simulated by image-guidance in real time, multiple redundant verification steps are eliminated, providing highly accurate screw placement while decreasing clinician error, device contamination, and surgical time, the decreased surgical time associated with decreased patient-recovery time and associated medical costs.

An improved method of fusing the sacroiliac joint and tools for accomplishing the same is disclosed. In one embodiment, the present invention is a method that uses an intra-articular joint fusion device for connecting the sacrum and ilium that includes creating a first incision in the patient's skin proximal to the patient's sacroiliac joint, inserting a surgical channel tool into the incision from the patient's posterior, creating a void in the sacroiliac joint, inserting a fusion implant into the void, the fusion implant having at least one fixation element for engagement with bone tissue in the articular surfaces of the sacrum and the ilium, and driving the fusion implant into the void such that the at least one fixation element engages with bone tissue in an articular surface of at least one of the sacrum and ilium, and the fusion implant fixes relative positions of the sacrum and ilium.

An apparatus for inserting implants in a bone comprising a frame having a cartridge receiving chamber and a barrel. A cartridge defining a plurality of chambers is positioned in the cartridge receiving chamber so the chambers are selectively alignable with a longitudinal passage of the barrel. At least one instrument is positioned in one of the chambers, and a plurality of implants is positioned in the other chambers. A drive assembly is engageable with the instrument and the implants. The drive assembly is slidably and rotatably disposed in the frame and is moveable between a retracted position, an engaging position wherein the distal end of the drive assembly is positioned to engage the selected one of the instrument and the implants, and an extended position wherein the drive assembly extends through the chamber to transport the selected one of the instrument or the implant from the chamber to the distal end of the barrel.

A two-piece suspension pedicle anchor and its system and component-set is disclosed. The two-piece suspension pedicle anchor comprises a proximal piece and a distal piece that can rotate relatively. An external thread is arranged on the outer surface of the proximal piece, and a transverse through hole for an artificial ligament to pass through is arranged at the distal piece. As the two-piece suspension pedicle anchor is rotated and gradually locked into the bone, only the proximal piece is rotated, and the distal piece with the artificial ligament is pushed down but not rotated; in addition, the artificial ligament will be brought into the bone along with the distal piece and sandwiched between the outer surface of the proximal piece and the bone, that is, the artificial ligament will be sandwiched and fixed between the anchor-bone interface without wrapping around the outer surface of the proximal piece.

A pectus bar pectus bar assembly can include a pectus bar and a stabilizer. The pectus bar can include a first portion including a first periphery and a second portion opposite the first portion. The stabilizer can include a stabilizer body including a recess engageable with the second portion. The stabilizer can also include a locking cam rotatable within the body to secure the stabilizer to the first portion.
