Abstract: An orthopedic fixation assembly for connecting to a bone includes a fixation plate having a hole, an insert securable to the hole and a screw securable to the insert. The fixation plate includes a shoulder recessed from its upper surface and an aperture. The insert includes a base portion and a flange extending laterally from an upper end of the base portion. The insert defines an insert central axis extending in a direction generally perpendicular to the flange. The screw has a screw head and the base portion has an insert hole with machined internal threads for engaging the screw. The insert hole defines an insert hole central axis extending in a direction at an offset angle relative to the insert central axis. The aperture of the fixation plate is dimensioned to receive the base portion of the insert and the recessed shoulder is dimensioned to receive the flange.

Abstract: An orthopedic fixation system having two rings or other base/frame elements separated by a plurality of struts. The struts are attached to the rings by a combination of a attachment mechanism having at least two degrees of movement each, and at least one connecting mechanism. The connecting mechanisms may be moveably or non-moveably connected to one or more tracks located on either or both rings of base elements. A combination of these elements provides a fixation device that allows for six degrees of freedom of movement between the rings or other base elements.

Abstract: A fixator system includes an active strut that that can be gradually or acutely adjusted. Adjustments can be made in six degrees of freedom. Embodiments of the active strut can provide for two of the six degrees of freedom being about a first common point of rotation, and another two of the six degrees of freedom being about a second common point of rotation. Embodiments of the fixator can include one or more active struts in combination with one or more passive struts. The passive struts can be rigidly locked or can be unlocked so as to be freely and acutely adjustable while gradual or acute adjustments are made using the one or more active struts.

Abstract: An intramedullary fixation device and related method for treatment of a Jones fracture. An exemplary device may comprise a rod having a distal section and a threaded proximal section, and means for securing the distal section within a first bone portion on a distal side of a fracture site. The device may also comprise a compression collar threadably received over the proximal section for providing compression to the fracture site, the compression collar comprising a threaded portion on its exterior surface configured to engage an interior of a second bone portion on a proximal side of the fracture site. In addition, the device includes an anti-rotational system engaging the compression collar to prevent rotation of the compression collar from its position providing the compression to the fracture site.

Abstract: A bone alignment implant includes a first bone fastener with a first bone engager that is adapted for fixation into the metaphyseal bone and a second bone fastener with a second bone engager that is adapted for fixation into the diaphyseal bone. A link connecting the two fasteners spans across the physis. Alternatively, the bone alignment implant is adapted for fixation into the diaphyseal sections of two adjoining vertebral bodies. These implants act as a flexible tethers between the metaphyseal and the diaphyseal sections of bone during bone growth. These implants are designed to adjust and deform during the bone realignment process. When placed on the convex side of the deformity, the implant allows the bone on the concave side of the deformity to grow. During the growth process the bone is then realigned. A similar procedure is used to correct torsional deformities.

Abstract: Disclosed embodiments relate to a fixation device for use in supporting and/or stretching an injured body part. An exemplary disclosed fixation device uses a thumb wheel control element to provide controlled rotational micromovements of a joint. The control element and its associated drive system allow for movement along a particular axis, while the position remains fixed with relation to the other axis. In addition, the fixation device may incorporate a drive system that introduces a simultaneous longitudinal translation with rotation, in order to provide for a common point of origin of rotation between the fixation device and the affected body part supported by the fixation device.

Abstract: A screw insertion/extraction device is disclosed that is useful as a tool for screw insertion and extraction procedures. The device includes a shaft sleeve that is formed to define a passage for accommodating the shaft of a wrench. In an exemplary embodiment, the shaft sleeve has a proximal portion and a distal portion interposed by an intermediate portion, where the proximal and distal portions extend along opposite sides of a central axis of the wrench shaft passage and the intermediate portion extends both along and about the central axis to connect the proximal and distal portions. A shoulder portion extends inwardly from the distal end of the shaft sleeve for engaging the base of a screw head such that the screw head can be captured between the distal end of a wrench and the shoulder portion of the shaft sleeve.
