摘要： An apparatus 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.

摘要： An apparatus for retaining first and second bone portions in a desired spatial relationship comprises a first member positionable along the first and second bone portions. A second member connectable with the first bone portion has surface member defining an opening. A fastener is extendable through the opening in the second member to connect the second member to the first bone portion. The fastener has a first portion for engaging the first bone portion and a second portion for clamping the first member against the second member to fix the first and second members against relative movement. The first member is also connected to the second bone portion.

摘要翻译： 用于以期望的空间关系保持第一和第二骨部分的装置包括可沿着第一和第二骨部分定位的第一构件。 可与第一骨部分连接的第二部件具有限定开口的表面部件。 紧固件可延伸穿过第二构件中的开口，以将第二构件连接到第一骨部分。 紧固件具有用于接合第一骨部分的第一部分和用于将第一部件夹持抵靠第二部件的第二部分，以抵抗相对运动来固定第一和第二部件。 第一构件也连接到第二骨部。
