    摘要： A spine retractor and distractor device comprises spinal process clamps and a retractor assembly, which may be rotatably coupled with the spinal process clamps. The retractor assembly may include a retractor ring, or frame, and a plurality of retractor blades adjustably coupled to the frame, e.g., by clamps. The spinal process clamps can maintain a grip on the spinal processes of the patient, and distraction pliers may be used to impart a distraction force on the spinal process clamps to distract the spinal segments. Additionally, other components, features, or tools, e.g., a light source and/or a camera, can be mounted on the instrument.

    摘要： An intervertebral implant for implantation between an upper vertebra and a lower vertebra having a central axis. The implant may have a first member with a top surface for contacting at least a portion of the upper vertebra and a bottom surface as well as a second member with a top surface and a bottom surface for contacting at least a portion of the lower vertebra. An elastic spacer may be disposed between the first member and the second member. The bottom surface of the first member and the top surface of the second member may have a first constraint means and the other of the bottom surface of the first member and the top surface of the second member may be provided with a second constraint means, to limit the amount of lateral movement between the first and second members. Additionally, the constraint means may be sized and configured such that a gap with a width greater than zero is provided at least transversely to the central axis between the first and second constraint means in an unloaded state.

    摘要： A fracture mobility testing system is provided for use in surgical procedures for augmenting vertebral bodies having collapsed due to compression fractures. The testing system is utilized to determine if the cortical shell of the vertebral body has begun to heal over the fracture lines to the point at which height restoration is not possible. Depending on the feedback provided by the testing system, the surgeon may elect to proceed with any of a variety of known height restoration techniques if the fractured portions of the vertebral body are still mobile, or may elect for a simple vertebroplasty procedure without height restoration if the feedback from the testing system determines that the cortical outer portions of the fractured vertebral body have fused to one another to the point at which height restoration is no longer an option.

    摘要： The invention relates to an aiming device (100) for boring a hole in a region of a bone (300) that lies in the vicinity of a joint. Said device consists of a U-shaped bow (110) comprising at least one contact element (120) on one end and on the other end of the bow (110) a screw spindle (130) that can be displaced in the direction of, or in the 141 opposite direction to the contact element (120), said spindle comprising a rotary grip (132) for clamping the device (100) on the region in the vicinity of the joint. The device also comprises a bore bushing (140), which can be placed on and removed from the end comprising the contact element (120). The compression of the bone that is generated by the bow (110) is maintained after the removal of the bore bushing (140) for the insertion of the bone screw.
