Abstract: A helical distractor, including: a distractor body having an open tubular shape including: a fixed footplate attached to a first end of the distractor body; first and second body edges; first and second key grooves in the first and second body edges, respectively; and an end cap at a second end of the distractor body; a movable foot including: body threads; a first key configured to engage the first key groove; a second key configured to engage the second key groove; and a movable footplate; an advancement screw with a threaded portion inside the distraction body, wherein the threaded portion is configured to engage the body threads of the movable foot, wherein the movable foot moves along the distractor body when the advancement screw is rotated, and wherein the distractor body is configured to cause the movable foot to rotate as it moves along the distractor body.

Abstract: A medical fixation system for bone repair including: a first orthopedic plate configured to attach to at least one bone, the first orthopedic plate having an inferior surface configured to contact bone and a superior surface that includes a first plurality of sternal plate engagement members; a second orthopedic plate configured to attach to at least one bone, the second orthopedic plate having an inferior surface configured to contact bone and a superior surface that includes a second plurality of sternal plate engagement members; and a third orthopedic plate configured to bridge the first and second orthopedic plates, the third orthopedic plate having a superior surface and an inferior surface, at least the inferior surface having a plurality of bridging plate engagement members; wherein the plurality of bridging plate engagement members is complimentary and opposite to the first and second pluralities of sternal plate engagement members, such that upon contact between the plurality of bridging plate engage

Abstract: A bone distractor, preferably an alveolar ridge distractor, having first and second bone plates sized and configured to engage opposing bone segments and an interconnecting mechanism operatively associated with the first and second bone plates such that rotation of an activation screw causes the second bone plate to move with respect to the first bone segment. The distractor may also include a housing having a first housing member operatively associated with the first bone plate and a second housing member operatively associated with the second bone plate, the second housing member being pivotally coupled to the first housing member such that the orientation of the second bone plate may be varied with respect to the first bone plate. Moreover, the second housing member may include a releasable closure cap so that the second bone plate may be easily removed and/or replaced, the second bone plate being provided in varying shapes and sizes.

Abstract: An external midface distractor is disclosed for attachment to the bones of a patient's cranium and midface region for performing an osteogenesis procedure to gradually lengthen a portion of the craniofacial skeleton. The midface distractor generally includes an external halo assembly for engaging the patient's cranium, a central adjustment assembly, a vertical central rod, at least one horizontal cross piece assembly including at least one distraction screw, and at least one bone engaging portion which is mounted to the targeted facial bone to be distracted. The midface distractor may also include various individual adjustment mechanisms that provide surgeons greater and more precise control over the distraction vector than is available with current devices. That is, the midface distractor may provide surgeons with additional anterior-posterior and medial-lateral adjustments, thus permitting surgeons to more precisely and accurately control the direction of distraction.
