SPINAL FIXATION SYSTEM

摘要

The present invention relates to a fastener assembly (10) for a spinal fixation system and is particularly useful in treatment of pediatric and small-statured patients. The fastener assembly (10) includes a fastener (12), an attachment member (14), and a locking member (16). The fastener (12) has a lower portion (20) for contacting a bone and a upper portion (22) integral with the lower portion (20) and having two open channels (35). Each channel (35) is configured and dimensioned for receiving a portion of the longitudinal member (18) along its circumference. The attachment member (14) is positionable on the fastener (12) and at least partially covers the channel (35) that receives the longitudinal member (18). The attachment member (14) is configured and dimensioned for receiving another portion of the longitudinal member (18) along its circumference. The locking member (16) is operatively associated with the upper portion (22) of the fastener (12) and secures the attachment member (14) and longitudinal member (18) to the fastener (12).
