Abstract: An instrument for use on a body site is provided comprising a bushing having portions, a coolant source, and a bore, wherein the instrument may be used to introduce an implant, instrument, or tool to a body site. After the implant, instrument, or tool is introduced to a body site, at least one portion of the bushing may be removed. A method of use for the instrument is also provided. A kit including the instrument is further provided.

Abstract: A bone tissue removal and harvesting device is disclosed and includes a cutting tool with a cutting head, a longitudinal shaft attached to the cutting head and a drive element. A container is located on the end opposite the cutting head for collection of the removed bone. The shaft can be made flexible to permit torsion and/or bending around the longitudinal axis without damage to the bone. During the cutting operation, the bone tissue is simultaneously removed and suctioned through an opening of the cutting head and conveyed through an axial shaft bore for collection in the container. The container is detachably mounted to the drive element and connected to the shaft so as to avoid substantial pressure drops from the cutting head to the container.

Abstract: A bone anchoring assembly includes at least one fixation plate and at least one bone anchoring element. Each bone anchoring element includes a circular-cylindrical hollow body with an upper end and a lower end, a connecting element that is pivotably mounted to a fixation plate or longitudinal support, an external thread that extends partially along the outer surface of the circular-cylindrical body for anchoring the bone anchoring element into the cortical portion of the bone, and a series of teeth located on the lower end of the circular-cylindrical body for cutting into bone.

Abstract: A bone plate includes an upper surface, a bone contacting surface, and at least one hole extending through the upper and bone contacting surfaces for receiving a bone screw. The at least one hole includes a first portion and a second portion that overlap one another. The first portion defines a substantially circular outer periphery and the second portion defines an elongated outer periphery that is elongated in a direction substantially parallel to the longitudinal axis of the plate. The first portion may have threads configured to engage threads on the head of a bone screw, and the second portion may be configured to cooperate with the head of a different bone screw to provide compression to the fracture.

Abstract: A bone anchoring assembly includes at least one fixation plate and at least one bone anchoring element. Each bone anchoring element includes a circular-cylindrical hollow body with upper and lower ends, a hemi-spherical connector that is pivotably mounted to and supported by fixation elements, an external thread that extends partially along the outer surface of the body for anchoring the bone anchoring element into the cortical portion of the bone, and a series of teeth located on the lower end of the body for cutting into the bone.
