A distractor device is used to apply force to a pair of distraction hooks each positioned between selected pairs of vertebrae. The hooks are eomponents of a spinal distraction system used in the treatment of spinal deformities or fractures. The distractor device ineIudes a threaded rod having a pair of force applying members shiftably mounted on the rod and each engaging one of the distraction hooks. A threaded nut on the rod engages and causes one of the force applying members to be moved away from the other force applying member to exert a distraction force on the distraction hooks. Each force applying member is pivotally mounted on the rod and is also comprised of a pair of pivotally connected elements whereby the pivoting movement between the force applying members and the rod permits positioning and adjustment of the distractor device in confined spaces.
