摘要:
An apparatus for retaining first and second vertebrae of a spinal column in a desired spatial relationship includes a longitudinal member positionable along the spinal column. A member, such as a plate, connectable with the first vertebra has first and second fastener openings and a portion engageable with the longitudinal member. A first fastener extendable through the first fastener opening in the member has a first end portion for attachment to the first vertebra and has a longitudinal axis. A second fastener extendable through the second fastener opening in the member has a first end portion for attachment to the first vertebra and has a longitudinal axis. The longitudinal axes of the first and second fasteners converge at an acute angle as viewed in a sagittal plane when the first and second fasteners connect the member with the first vertebra. The member connectable with the first vertebra has a body portion and has a lip portion projecting from the body portion of the member. The lip portion of the member is engageable with a surface of the first vertebra facing toward the second vertebra.
