Abstract
An apparatus (10, 110) for use in retaining vertebrae (V) of a spinal column in a desired spatial relationship includes a longitudinal member (12, 112) having a longitudinal axis (13, 113) extendable along the spinal column. A hook (14, 114) connects the longitudinal member (12, 112) to a vertebra (V) of the spinal column. The hook (14, 114) is connectable with the longitudinal member (12, 112) and engageable with the vertebra (V). The hook (14, 114) has a first portion (16, 116) which extends adjacent a first surface (64, 164) of the vertebra (V) when the hook is connected with the vertebra. A second portion (18, 118) of the hook (14, 114) extends adjacent a second surface (62, 162) of the vertebra (V) when the hook is connected with the vertebra so that the vertebra is received between the first and second portions (14, 114 and 18, 118). The second portion (18, 118) is movable relative to the first portion (14, 114) in a direction transverse to the longitudinal axis (13, 113) of the longitudinal member (12, 112) to adjust a distance between the first portion (14, 114) and the second portion (18, 118).
