Abstract

A hook inserter device is used for positioning a distraction hook for spinal distraction systems in the treatment of spinal deformities and fractures. The hook inserter device comprises an elongate bar including a handle portion and a hook mounting portion, the latter being of reduced cross-sectional size to permit a distraction hook to be mounted thereon. A positioning member on the bar prevents rotation of the distraction hook during application of the hook to the spine. A retaining member on the bar engages and holds the distraction hook on the mounting portion during placement of the hook but permits ready release thereof after placement of the hook.
