Tensioner instruments, systems, and methods of tensioning flexible bands in-situ. The tensioner instrument may include first and second pivoting arms with a base for pinching and pulling the flexible band to provide tension. The tensioner instrument system may include a clip inserter and a ratcheting tensioner for tensioning the band through an implant. The instruments may be configured to apply and maintain tension to the flexible band, thereby providing the desired correction to the spine.

Implants, systems, and methods for securing a flexible band, thereby providing a desired correction to the spine. The implant may secure the flexible band to patient anatomy without the use of pedicle screws or spinal rods. The implant may include a locking member configured to secure the band. The band may be looped around bony anatomy and tensioned to achieve correction and provide fixation as an alternative to pedicle screws and spinal rods during spinal deformity surgery.

A tether tensioner includes a handle assembly, an elongate member extending distally from the handle assembly, and an engaging portion. The handle assembly includes a stationary member, a trigger pivotably coupled to the stationary member, and a spool rotatably supported on the stationary member. The spool is configured to wrap a tether thereabout. The spool is operatively coupled with the trigger such that pivoting of the trigger relative to the stationary member causes rotation of the spool. The elongate member includes a channel configured to slidably receive a tether therethrough. The engaging portion is configured to receive a head portion of a bone screw such that a tether extends from the head portion disposed in the engaging portion to the spool through the channel of the elongate member.

Tension isolating adjustable adapters are disclosed, along with kits and systems containing same, as well as methods of production and use thereof. The tension isolating adjustable adapters include a percutaneous device holder that can be releasably connected to a percutaneous device via a locking element, and a tensioning member that engages the percutaneous device holder. The tensioning member has at least one tension pad that is shaped and configured to be disposed about the percutaneous device insertion site in the patient's skin, and the engagement of the tensioning member(s) to the percutaneous device holder allows for adjustment of the tension pad(s).

A traction tensioning apparatus includes a housing that has a first end and a second end. An anchor point is mounted to the housing and is attachable to a first tether is in-line with a traction system and extending away from the housing in a first direction. An urging assembly is engaged with the anchor point. The urging assembly is tension actuated to urge the anchor point toward the second end and releasably actuated to allow the anchor point to move toward the first end. An attachment point is mounted to the housing and is attachable to a second tether in-line with the traction system and extending away from the housing in a second direction. The attachment point is movable in the first and second directions relative to the housing. A biasing member is engaged with the attachment point and biases the attachment point in the first direction.

A device including a first plate configured to interface with a first bone structure of a joint; a second plate configured to interface with a second bone structure of the joint opposite the first bone structure; and at least one mechanical actuation mechanism disposed between the first plate and the second plate and configured to apply a distraction force along an axis between the first plate and the second plate so as to urge the first plate and the second plate away from one another, wherein the device is configured so as to have a range of motion ranging from a minimum distance between the first plate and the second plate to a maximum distance between the first plate and the second plate, and wherein the mechanical actuation mechanism is configured such that the distraction force is substantially constant distraction force across the range of motion.

The disclosure relates to an iliac crest displacement device comprising: an engagement member for engaging an iliac crest of a subject; and a pulley assembly for causing the engagement member to move the iliac crest inferiorly, thereby displacing the iliac crest relative to a rib cage of the subject.

Implants, systems, and methods for securing multiple cords to bone. The fixation system may be used for correcting scoliosis with a fusionless double corded device. The system may include first and second cords, a single bone fastener, one or more tulip structures configured for receiving one or both of the first and second cords, and one or more locking caps adapted to lock one or both of the first and second cords.

Provided is a device for tensioning a wire in conjunction with an external bone fixation (EBF) device. A swivel hinge body comprises two forks extending in a plane parallel from the swivel hinge body. A lower lip extends from the swivel hinge body below and in parallel with the two forks. A swivel pin and a swivel block are positioned between the lower lip and the plane of the two forks and held in place by the swivel pin such that the swivel block is able to rotate in an arc with respect to the lower lip and the swivel hinge body. The swivel block comprises a face, wherein the face is configured to fit against an edge of a component of the EBF device such that, when the tensioning mechanism is applying tension to the wire, the swivel hinge body is prevented from deflecting to one side.
