Bone anchoring device

摘要

A bone anchoring device including a clamping device and a flexible band configured to be secured a vertebra. The clamping device includes a base member and an upper member configured to be secured together with a fastener. The flexible band is configured to be passed around a bone portion and through a passage of the base member to position the flexible band between a clamping surface of the base member and a clamping surface of the upper member. The flexible band is tensioned to urge the clamping device against the bone portion and then clamped between the clamping surfaces of the base member and the upper member. A stabilization member of a vertebral stabilization construct may be secured to the vertebra with the bone anchoring device without invasively altering or impairing the structural integrity of the vertebra.
