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.
Spinal Curvature Modulation Systems and Methods
Spinal curvature modulation systems, methods and related devices and instrumentation are disclosed, which include a flexible tether, a tether tensioning unit and bone anchors for the flexible tether that allow the tether to be secured across multiple vertebrae in a region of treatment. When the flexible tether is attached to multiple vertebrae, it can be used to correct spinal deformities. Tension in the flexible tether is adjustable transcutaneously without invasive surgical procedures by use of remotely driven actuators, such as a magnet-driven motor, or by a small tool insertable through a small incision. Disclosed systems and methods thus allow for multiple adjustments of tether tension, and spinal curvature, over time without repeated, highly invasive, spinal surgeries.
Cable-locking plate with screw
The cable-locking plate with screw allows for compression of bone fractures using a tensioned cable. The cable-locking plate with screw allows the use of a cable as a flexible bridging member, such as a cable, helps create compression while accommodating the unusual shape. The cable-locking plate with screw allows a surgeon to tension a cable through the plate, then grip the cable by tightening a screw associated with the plate. The compression is created is across the fracture, not around the bone, thus avoiding compression of nerve and blood vessels along the bone's surface. The cable is guided into an ideal position using cable channels, allowing the surgeon to concentrate on tension and screw compression. The plate and cable system are then left in the patient while the bone mends. The cable-locking plate with screw is either left permanently or removed during a later surgery.
SURGICAL FASTENING
Methods of joint repair employing sutures and attached fixation devices are discussed. For example, a bone block graft procedure (e.g., Latarjet) is discussed which employs fixation devices to secure contact between graft surfaces of two bones. A suture construct, including a continuous suture loop routed through a first fastener, is secured to a first bone. Looped ends of the suture loop are passed through passageways formed in the two bones. The looped suture ends are further routed through a second fastener. The second fastener is mounted to the second bone and a sliding knot, formed in the looped suture ends, is advanced into contact with the second fastener. The suture is further tensioned using a tensioner device to secure the two bones together.
STERNAL CLOSURE SYSTEM
A system including a bone punch tool and a needle guide. The bone punch tool can include a support arm having a support arm proximal portion and a support arm distal portion, a pivot arm having a pivot arm proximal portion and a pivot arm distal portion, and an arcuate punch configured to punch through bone. The pivot arm distal portion can be pivotably coupled to the support arm distal portion, such that the pivot arm proximal portion is configured to be moved away from the support arm proximal portion to extend the arcuate punch into a punch position to punch an arcuate hole through bone. The needle guide can be configured to guide a needle through the arcuate hole.
Coracoclavicular fixation device and related method thereof
An adjustable and self-locking fixation device for fixedly securing two structures wherein the device comprises two spans and a receiving aperture configured to receive the spans and form a closed loop around a first structure. The two spans are further configured to secure and lock onto each other so as to form a second closed loop around the two structures and secure the two structures in a tensioned state.
SCOLIOSIS CORRECTION SYSTEMS, METHODS, AND INSTRUMENTS
Devices, systems and methods for use in spinal surgeries. The system may include a fastener system comprising a fastener, a staple, and a locking cap. A cord may extend along the spine and through at least one fastener system. An instrument may be provided for tensioning the cord. The system may, for example, apply fixation on the convexity of the scoliotic vertebrae to limit growth on the convex side and allow unilateral growth on the concave side.
APPARATUS AND METHODS FOR SPOOLED VERTEBRAL ANCHORS
Apparatus and method for dynamic connection between adjacent bones. Various embodiments pertain to a bone anchor that includes a rotatable spool, the spool being configured to place tension on a flexible member, such as a tether, suture, cable, or other. Still further embodiments pertain to tools for interconnecting two bone anchors with a tether.
Bone fixation system with opposed mounting portions
System, including methods, apparatus, and kits, for bone fixation using a fixation device including a mounting portion and a fastener that attaches to the mounting portion. In some embodiments, the fixation device may include first and second mounting portions configured to be disposed across a bone from each other and secured with a fastener that extends from one of the mounting portions, through the bone, and to the other mounting portion. The system also may include a tool to facilitate installation of the fixation device.
Surgical fastening
Methods of joint repair employing sutures and attached fixation devices are discussed. For example, a bone block graft procedure (e.g., Latarjet) is discussed which employs fixation devices to secure contact between graft surfaces of two bones. A suture construct, including a continuous suture loop routed through a first fastener, is secured to a first bone. Looped ends of the suture loop are passed through passageways formed in the two bones. The looped suture ends are further routed through a second fastener. The second fastener is mounted to the second bone and a sliding knot, formed in the looped suture ends, is advanced into contact with the second fastener. The suture is further tensioned using a tensioner device to secure the two bones together.
