Abstract: A spinal fixation system for connecting a spinal vertebra to a rod, including a clamp and screw, the clamp having screw, band and rod channels. The rod channel extends through the clamp forming a passage for a rod, being open towards a lateral side and running approximately perpendicular to the screw channel. The band channel is adjacent to the screw channel and forms a passage for a flexible band. The screw channel has an internal screw thread for engagement with the screw to allow it to be advanced from a first band-locking position into a second rod-locking position. In the first position, the band channel is compressed to inhibit movement of the band with respect to the clamp, while allowing axial movement of the rod within the rod channel. In the second position, the rod channel is restricted to inhibit axial movement of the rod within the rod channel.

Abstract: The provision of a pass that may be used in the field of infectious disease prevention and control and, more specifically, a method for the provision of a verified health pass that is indicative for at least one health status of an individual and can be used for allowing entry to a venue depending on said specific health status. The verified health pass may further be used for linking an individual's identity to an associated proximity detection device to allow contact tracing of individuals inside a venue while minimizing transfer of personal data.

Abstract: A bone screw includes a screw shaft with an external thread. The screw shaft anchors the bone screw in a bone. A proximal end of the screw shaft includes a screw head. The ratio between the outer thread diameter and the thread core diameter increases toward the screw head in a proximal screw shaft portion or in the area of the thread's run-out.

Abstract: A spinal manipulation device (30; 80; 90; 100) adapted to protect, in use, a spinal cord from excessive axial and/or shear translations, the spinal manipulation device comprising a guide (31, 32; 81, 82, 83; 91, 92, 93; 101, 102, 103) configured to constrain, in use, movement of a first arm (35; 86; 96;106) relative to a second arm, the first arm and the second arm being fixable to and extending from a segment of spine undergoing manipulation, wherein, in use, the guide constrains movement of the first arm (35; 86; 96; 106) relative to the second arm (36; 87; 97; 107) to be about a substantially fixed centre of rotation located at least partially within the segment of spine undergoing manipulation, thereby protecting the spinal cord from excessive axial and/or shear translations.
