摘要：
An apparatus for connecting a structure with a vertebral body of a spinal column and for transmitting a load between the structure and the vertebral body. The apparatus includes a fastener with a threaded portion for threaded engagement with a surface defining an opening in the vertebral body to connect the vertebral body with the structure. A spacer is adapted to be located between the fastener and the structure for transmitting load therebetween. The spacer is made of a material which plastically deforms as a function of time and load applied thereto to decrease the load transmitted between the vertebral body and the structure.
