  • Patent number: 9023053
    Abstract: A system for performing a resection of a selected portion of an anatomy with a resection instrument. The system includes a first member, a first movement defining portion defined by the first member, a second member, and a second movement defining portion of the second member. The first member is fixable to the selected portion of the anatomy. The second member is configured to cooperate with the first member. The first movement defining portion and the second movement defining portion are operable to allow the second member to be moveable relative to the first member from a first position to a second position. The resection instrument is positionable relative to the second member in the first position and in the second position to form a selected resection of the selected portion of the anatomy.

  • Patent number: 8998957
    Abstract: A rod connector for joining a first rod and a second rod includes bore holes that are offset and/or non-parallel to each other. The rod connector provides an offset or non-parallel connection between the rods that allows for the rods to match the contour of a patient's body without requiring bending of the rods. The rod connector may include a first bore hole for receiving the first spinal rod and a second bore hole for receiving the second spinal rod that is adjustable relative to the first bore hole to adjust the position and/or orientation of the second spinal rod relative to the first spinal rod. The rod connector may comprise a first housing component defining the first bore hole and a second housing component that is movable relative to the first housing component and defining the second bore hole.

  • Patent number: 8956359
    Abstract: A bone saw including a flexible, rectangular saw blade having a central longitudinal axis and a cutting edge at a distal tip, and a shaft. The shaft has a central longitudinal axis, and a blade passage within the shaft that houses the saw blade, where the central longitudinal axis of the saw blade, of the shaft, and of the blade passage, are parallel. Further included is a blade opening located through a distal end of the shaft and of the blade passage, the blade opening being perpendicular to the longitudinal axis of the shaft. Also, a curved abutment can exist within the blade passage, aligning the saw blade with the blade opening. Distally translating the saw blade within the blade passage can cause the saw blade to conform to the curved abutment and exit the blade opening with the cutting edge essentially perpendicular to the longitudinal axis of the shaft.

  • Patent number: 8951288
    Abstract: An implant and method are provided for treating a fractured bone. The implant includes a generally elongated member having a first configuration for introduction between body tissue layers and a second configuration in-situ having a curved portion. The generally elongated member includes a plurality of alternating projections and slots and a plurality of occlusions wherein each of the occlusions is positioned between adjacent projections. The occlusions at least partially occlude an upper and/or lower side of the associated slot. Additionally, the projections may be configured to overlap each other when the implant is deployed in the second configuration. The occlusions and/or overlapping projections promote improved fluid flow and dispersion through the deployed implant and into the fractured bone. Also provided are methods for using the implant to treat a bone fracture.

  • Patent number: 8932300
    Abstract: Methods and instruments for treating an osteoporotic vertebral body or for treating a vertebral compression fracture. An exemplary method includes introducing an open knit structure together with a bone cement into a bone wherein the knit structure extends substantially throughout the interior of the cement volume. In one aspect of the invention, the bone cement volumes cures with the filament structure reinforcing the cement. In another aspect of the invention, the open knit structure is configured to direct flows of bone cement to apply forces for reducing a vertebral compression fracture. In another aspect of the invention, the system provides bone cement flows that extend through the knit structure thus allowing the cement to fully interdigitate with the cancellous bone.
