    摘要： A flexible chain implant for insertion into an interior volume of a vertebral body. The implant may be implanted in an insertion position for sliding through a cannula and is flexible for packing into the interior volume in an implanted configuration. The implant randomly separates in the implanted configuration. The implant includes a top member and a bottom member, wherein the top and bottom members are coupled to one another at a coupled portion. The top and bottom members preferably each include an inner surface such that the inner surfaces include a plurality of alternating projections and recesses so that the projections are received within the recesses in an insertion position. Alternatively, the implant may include a plurality of substantially non-flexible bodies and a plurality of substantially flexible links interconnecting the bodies. The non-flexible bodies include a plurality of facets and/or abutment surfaces.

    摘要： Methods and apparatus for providing an overlay image of an implant during a surgical procedure using a mobile computing device are provided herein. The implant may include radio-opaque internal markers adjacent to and defining edges of the implant. The method may include: capturing an image of a imaging display device screen; estimating a pose of the implant based on the relationship between the 2-D positions of the radio-opaque internal markers and the 3-D positions of the radio-opaque internal markers; retrieving or generating a 3-D model image of the implant at the determined pose using the 3-D implant data; and overlaying the 3-D model image onto the image of the implant. The captured image may include the implant and at least two of the radio-opaque internal markers being visible as fiducial markers within the image. The fiducial markers may be 2-D positions of the radio-opaque internal markers in a 2-D plane.

    摘要： A bone anchor (100) for attaching a rod (108) to a bone has an anchor member (106) for attachment to the bone and an anchor head (104) having a U-shaped opening for receiving the rod. The bone anchor also includes a locking cap (102) that has a main body (900) and a set screw (1000). Advantageously, in one embodiment the locking cap preferably is designed such that a single tool can be used to lock the locking cap in place on the anchor body preferably with a 90° turn and preferably then drive the set screw to clamp the rod. The locking cap also preferably non-threadingly engages the anchor body. The anchor body preferably has an inclined surface on its top surface which elastically deflects extending tabs on the main body to secure the locking cap to the anchor body. A method of implantation and assembly of the bone anchor are also described.
