摘要： A bone graft containment device includes a body extending longitudinally from a first end to a second end. The body includes a channel extending longitudinally therethrough. The device also includes a fluid delivery structure received within the channel. The fluid delivery structure includes a central tubular member extending along a length of the channel and a laterally extending tubular member extending laterally from the central tubular member to a fluid receiving opening. The central tubular member includes a plurality of openings extending laterally through a wall thereof, so that, when the fluid receiving opening is connected to an external fluid source, fluid is passed through the laterally extending tubular member and the central tubular member to be dispersed to a graft material packed within the channel via the plurality of openings.

摘要： A bone plate defines an interior surface that defines: a hole extending through the plate along an axis; plate threads configured for locking with a threaded head of a locking screw; first, second, and third columns sequentially located about the axis; a first corner extending tangentially from the second to the first column; and a second corner extending tangentially from the third to the first column. The first and second corners are substantially equidistantly spaced from the axis. The plate threads extend across the first, second, and third columns and the first and second corners. The interior surface defines a recess between the second and third columns and facing the first column. An apex of the recess is spaced further from the axis than are the first and second corners, such that the recess circumferentially interrupts at least a portion of at least one of the plate threads.

摘要： A bone fracture fixation system including reference pins inserted into bone fragments of a patient in a first configuration and an image capture device configured to capture an image of the reference pins, and the bone fragments. The system includes a processor configured to receive and pre-process the captured image data. The processor pre-processes the image data by virtually re-positioning the reference pins in the first configuration into a second configuration, wherein the re-positioning virtually re-positions the bone fragments into normal alignment; and virtually generating a support device. The system includes a point-of-care production apparatus that produces a three-dimensional model of the virtually generated support device in a form that can be applied to the patient. The three-dimensional support device generated by the point-of-care production apparatus is configured to receive the reference pins in the first configuration; and simultaneously re-positions and fixes the bone fragments into normal alignment.

摘要： A bone fixation system includes a bone plate having an outer surface, an opposed bone-facing surface, and an interior surface that defines a hole extending from the outer surface to the bone-facing surface along a central hole axis. The interior surface further defines a compression surface. The system includes a bone fixation member having a shaft extending from a head along a central fixation member axis. The head has an exterior surface that defines a threaded head portion configured for variable angle locking with a complimentary variable angle plate locking structure. The compression surface and the threaded head portion are cooperatively configured to translate the bone plate in a direction substantially perpendicular to the central hole axis when the threaded head portion contacts the compression surface when the bone fixation member axis is offset from the central hole axis at an offset parameter as the head advances within the hole.
