System and method of soft tissue anchoring to metaphyseal bone plate
A bone plate a re-orientable tab that provides a buttress support to fragments of the surrounding concave joint rim. The tabs can be re-orientated to contact the rim to provide close support. Each tab includes a hole sized to closely receive a K-wire to permit the K-wire to apply a bending load to a tab in situ to bend the tab about a lower recess between the tab and the remainder of the head. A soft tissue anchor is sized to pass through the hole in the tab, and into a hole drilled into the underlying bone. The soft tissue anchor has a bone engaging first portion and second portion comprising a length of flexible suture, to which is affixed a needle. The needle and suture can be used to draw tissue about the joint capsule.
BONE PLATES WITH DYNAMIC ELEMENTS AND SCREWS
A bone plate assembly may include a bone plate with an obverse side, a reverse side, a fastener hole formed through the bone plate from the obverse side to the reverse side, a first draw hole formed through the bone plate from the obverse side to the reverse side, with a wire engagement surface, a fastener insertable through the fastener hole and into tissue, and a first wire insertable into the first draw hole, with a distal end anchorable in the tissue and a proximal end with a retention portion that is retainable in the first draw hole. The wire engagement surface may be oriented obliquely relative to a pilot hole formed in the tissue to receive the wire such that motion of the first wire through the first draw hole exerts a compressive force against the tissue.
SYSTEMS AND METHODS FOR PLANNING, PERFORMING, AND ASSESSING SPINAL CORRECTION DURING SURGERY
Methods are provided for planning, performing, and assessing of surgical correction to the spine during a spinal surgical procedure. These methods are implemented by a control unit through a GUI to digitize screw locations, digitize anatomical reference points, accept one or more correction inputs, and generate one or more rod solution outputs shaped to engage the screws at locations distinct from the originally digitized locations.
Systems, devices, and methods for designing and forming a surgical implant
A method is provided for determining the shape of a surgical linking device that is to be attached to a bony body structure such as the spinal column based on digitized locations of a plurality of attachment elements engaged to the bony structure. The method is implemented by a computer system through a GUI to generate an initial bend curve to mate with the plurality of attachment elements. The initial bend curve may be simplified based on user input to the GUI to reduce the number of bends necessary to produce a well-fitting linking device and may be altered to help obtain the goals of surgery.
METHODS PROVIDING BEND PLANS FOR SURGICAL RODS AND RELATED CONTROLLERS AND COMPUTER PROGRAM PRODUCTS
Systems providing robotic bending used to bend a surgical rod are disclosed. Such systems may include a processor and memory coupled with the processor. The memory includes computer readable program code so that when the computer readable program code is executed by the processor, the processor performs operations including providing a set of transformation points corresponding to respective attachment implants, generating a bend plan for the surgical rod based on the set of transformation points, and generating an image output to render the set of transformation points and the bend plan on a display. Related methods and computer program products are also discussed.
Methods, systems and apparatuses for torsional stabilization
Methods, systems and apparatuses are provided for torsionally stabilizing a spinal motion segment. One or more implants are placed between two vertebrae to provide torsional stabilization. In particular, one or more implants may be fixed between a superior vertebral body, such as at the spinous process, and an inferior vertebral body. The implants may be connected to the superior vertebral body using a fixation device such as a turnbuckle, an outrigger, a thimble, an endobutton, a suture plug or combinations thereof. The implant may also be connected to the inferior vertebral body using various types of hardware, including staples, screws and anchors. The implant may be kept in tension to provide torsional stabilization and may be comprised of one or more sutures. A multi-functional instrument having one or more arms having holes can be used to clamp onto the superior vertebral body and guide one or more implants to various locations for fixation in accordance with the methods described herein.
LOAD DISTRIBUTOR FOR A STERNUM CLOSURE DEVICE AND TOOL FOR CUTTING THE LOAD DISTRIBUTOR
A load distributor for a sternum closure device comprises a wire receiving section configured to be attached to a wire of the sternum closure device, and a load distributing section. A tool for cutting the load distributor comprises a pair of jaws movable between a load distributor receiving position and a cutting position, wherein at least one of the jaws has substantially V-shaped cutting edges tapered towards the other jaw in an angle to the longitudinal extension of the tool.
Composite material spinal implant
A pedicle screw implant construct kit, comprising at least one pedicle screw, at least one collar comprising a recess for receiving a rod, the collar configured to be coupled to a head of the pedicle screw, an elongated rod for connecting the collar to one more additional collars to couple between the pedicle screw and one or more additional screws, and a locking ring sized to be positioned over at least a distal portion of the collar to restrain relative movement of the screw head and rod by exerting radial compression force onto the collar. In some embodiments, the components of the kit are comprised of carbon reinforced composite material, optionally with no radiation blocking material. In some exemplary embodiments of the invention, the kit includes two locking rings on a collar, optionally both below the rod.
Tool for crimping orthopedic cable
A crimping tool for crimping a crimp onto a cable includes a crimping unit, a housing unit, and a tensioning unit. The crimping unit includes an inner crimping tube having a distal end configured to receive the cable; and an outer crimping tube mounted around the inner crimping tube. The housing unit is configured to receive the outer crimping tube, and includes a housing having an open lower portion; a trigger-handle; and a first hinge connecting the trigger-handle to the housing. The tensioning unit is mounted to the housing, and is configured to apply tension to the cable. The trigger-handle releasably engages the open lower portion of the housing by rotation about the first hinge; and the outer crimping tube is configured to move in an axial direction relative to the inner crimping tube to crimp the cable when actuated by the trigger-handle.
CONTOURED BONE PLATE WITH LOCKING SCREW FOR BONE COMPRESSION, PARTICULARLY ACROSS A TARSOMETATARSAL JOINT
A method of applying a bone plate across a tarsometatarsal joint or two different portions of a metatarsal may involve positioning a bone plate across a separation between two bone portions. The bone plate can have at least two fixation holes and a bend between the holes. A locking screw can be inserted through one or both holes that has a head thread and a shaft thread, where the shaft thread has a pitch greater than a pitch of the head thread. The locking screw can be screwed into an underlying bone portion until the bend in the bone plate is deformed.
