The present disclosure is directed to a spring loaded cervical traction collar having front and rear discrete body halves in which each body half is split in half horizontally to define upper and lower front parts and upper and lower rear parts. A plurality of traction spring units each having double ended plunger rods having a head on each free end, a pair of closed ended cylinders and a spring is located in each of the cylinders. The springs are between the heads and the closed ends of the cylinders. Each cylinder is secured in one of said body halves. The springs urge the vertically opposed body halves in which each traction spring unit is secured to provide traction and are circumferentially spaced about the front and rear body halves and secured thereto with the axes of their plunger rods being substantially parallel to one another. Mating Velcro straps connect the upper front body part to the lower front body part while additional mating Velcro straps connect the upper rear body part to the lower rear body part and the spring loading of each unit permits selection of variable thrust loading circumferentially about the neck of a patient to provide prescribed vertical traction thrust of the head of a patient.
