Abstract
Abstract An orthopedic treatment table conceived to be operated by the patient himself and arranged to effect spinal traction by the action of gravity on the body of the patient supported in recumbent position on a plurality of table top sections, all slidably mounted onto an angularly elevatable frame relative to a supporting base. Crank-operated latches are provided to lock any table top section to an adjacent table top section relative to the frame, such that the table top sections can be variably connected relative to each other.
