    摘要： Translational bone fixation assemblies, kits containing such assemblies, and methods of use are described herein. The described assemblies may be used in spinal fusion procedures in which a damaged or diseased disc (or part of a disc) is removed from between a pair of vertebrae and a spinal fusion spacer is placed between the vertebrae. The assemblies may be applied to an anterior portion of the affected vertebrae to span the affected disc space, and may be fixed to the vertebrae using bone screws. The assemblies may function to maintain the vertebrae aligned during the initial period following fixation in which fusion of the spacer to the adjacent vertebrae occurs. The assemblies may also function to share some of the axial spinal load applied to the fusion spacer to prevent extreme subsidence of the spacer into the vertebral body, such as where the patient has poor bone quality.

    摘要： A bone stabilization or fixation assembly may include a bone plate having an upper side and an underside and at least one fixation hole having a first diameter and the hole extending from the upper side to the underside. The area of the bone plate adjacent the fixation hole has a first thickness. The bone stabilization assembly further includes at least one fastener having a head, a shaft, and a relief. The head has a larger dimension than the shaft. The shaft may have threads having a pitch, a core diameter and an outer thread diameter. The relief has a length and a second diameter. The first diameter of the fixation hole may be smaller than the outer thread diameter but larger than the second diameter of the relief. Also, the length of the relief may be greater than the first thickness of the bone plate. The first diameter may be greater than, equal to, or less than the core diameter of the shaft.
