2.7 Cervical Traction Vector
The modular table base is equipped with a cervical traction vector (see Figure 8). The
cervical traction vector provides the adjustability of the angle of pull for cervical traction
as shown in Figure 9.

2.8 Pulley Assembly
The pulley assembly is permanently attached to the head end column to guide a traction
rope. The cervical traction vector attaches to the medial side of the head end H-frame
in the mounting holes to achieve the desired angle of traction (see Figure 9). Sandbag
weights may be added to provide the appropriate traction load during anterior or
posterior cervical surgery or any other time cervical traction is desired. The traction
weight is connected to a rope, which passes over the pulley assembly, threads through
the pivot shaft of the head end crossbar and connects to the patient traction apparatus
(see Figure 10).
NOTE: The amount of traction load applied to the patient is completely at the discretion
of the attending physician.
