Abstract: Methods, apparatus and systems for constraining spinous processes to elastically limit flexion of two or more adjacent spinal segments rely on placing a tether structure over at least three adjacent vertebral bodies or two adjacent vertebral bodies and the sacrum. The tether structures may be continuous, for example in the form of a continuous loop, or may be discontinuous, for example in the form of a loop or elongate element having at least two anchor structures for securing in bone.

Abstract: A dynamic spinal stabilization system that enables spinal movements throughout a range of motions from a neutral condition of the spine, to a flexion condition, and an extension condition. The system includes elastomeric members operatively located to substantially eliminate metal-to-metal contact of metal components of the system that are movable relative to one another, one of the elastomeric members having a stepped configuration.
Abstract: This invention improves upon prior art total disc replacements (TDRs) by more closely replicating the kinematics of a natural disc. The preferred embodiments feature two or more fixed centers of rotation (CORs) and an optional variable COR (VCOR) as the artificial disk replacement (ADR) translates from a fixed posterior COR that lies posterior to the COR of the TDR to facilitate normal disc motion. The use of two or more CORs allows more flexion and more extension than permitted by the facet joints and the artificial facet (AF). AF joint-like components may also be incorporated into the design to restrict excessive translation, rotation, and/or lateral bending.
Abstract: A device for measuring a degree of bending of an intramedullary nail comprises a probe sized and shaped for insertion into a cannulation of an intramedullary nail. The probe including a first longitudinal element extending along a longitudinal axis from a distal end to a proximal end and a second longitudinal element extending along a longitudinal axis from a distal end to a proximal end, the distal ends of the first and second longitudinal elements attached to one another so that the longitudinal axes of the first and second longitudinal elements extend substantially parallel to each other and define a middle plane. A measuring element measures relative axial displacement of the proximal ends of the first and second longitudinal elements in the middle plane upon bending of the first and second longitudinal elements as the probe is inserted into a cannulation of the intramedullary nail.

Abstract: A mobile device is adapted to at least partially replace the motion characteristics of a natural inter-vertebral disc positioned in a disc space. In an embodiment, a receptacle is coupled to the bearing surface. The receptacle is adapted to accept an implantable material without the removal of the bearing surface, wherein the implantable material contacts the abutment surface of each of the vertebral bodies adjacent to the disc space and leads to fusion and immobilization of two vertebral bodies adjacent the disc space.
Abstract: MIS TLIF systems and related methods. Implementations of distractor devices may include a first portion and a second portion where the second portion is slidably coupled over the first portion. A position of the second portion relative to the first portion may be adjustable through contacting a distractor latch coupled to the second portion with a plurality of teeth on a side of the first portion. The first portion may include a first pedicle screw pin on an end of the first portion opposing the second portion. The second portion may include a second pedicle screw pin on an end of the second portion opposing the first portion. The first pedicle screw pin and the second pedicle screw pin may be both configured to couple with a pedicle screw head. A length of the distractor device may be configured to be adjustable through sliding of the first portion.
Abstract: Embodiments of the present disclosure are directed to a systems, devices and methods for displacing bones of a living mammal. In some embodiments, a device is provided which includes at least two engagement elements positioned at a distance from each other for engagement with two separate bones Each of the engagement elements may be carried by a support part which in turn is supported in a support portion of a distance unit (5). The said support part and support portion form a support unit, where each engagement element extends at an angle (?) with respect to a straight line (L) between two support units. At least one of the support units includes an arrangement for altering the angle which includes an actuating unit maneuverable for adjustment of the angle (?). Some embodiments of the disclosure are directed to a system for engagement with vertebrae including such devices (noted above), as well as uses of the device and associated methods of treatment.

Abstract: A tool is disclosed for use in distracting and compressing fractures of any of a variety of bones. In particular, the tool has a pair of engaging arms, one arm having a hook element to engage a bone plate connected to one side of a fracture, and the other arm having at least one recess for engaging a head of a bone screw or guide wire connected to the other side of the fracture. Actuation of the tool causes the opposing bone segments of the fracture to be pushed apart or drawn together, depending on whether the tool handles are squeezed together or pulled apart. The tool may have a scissors joint that allows the ends of the tool to maintain a parallel alignment during operation, thus reducing the chances for misalignment of the bone segments during operation.
