摘要： The present invention is directed to a transconnector (10) for coupling first and second spinal fixation rods or other elongate fixation elements (12; 14). The transconnector (10) includes a male member (16), a female member (18), and a locking member (20). The male member (16) has a body with a linking element (22) (such as a hook) associated with the lateral end for receiving one of the fixation elements (12; 14), and a projection (24) on the medial end. The projection (24) includes a recess (32) defined by lateral and medial walls (34; 36). The female member (18) has a body with a linking element (26) associated with the lateral end for receiving the other fixation element (12; 14), and a cavity (28) with an opening (30) on the medial end for receiving a portion of the male member projection (24). The locking member (20) secures the position and orientation of the male member projection portion in the cavity (28) in order to accommodate different separation distances and orientations between the first and second fixation elements (12; 14). The locking member (20) cooperates with the medial wall of the recess (32) of the projection (24) to prevent uncoupling of the male and female members (16; 18). The male member (16) may be made as a two component assembly in which the two components can rotate relative to one another for accommodating rod convergence or divergence.

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).
