Motorized Robotic Closed Cervical Traction: Biomechanical Proof of Concept.

Study Design: Biomechanical study.

Objective: To demonstrate that robotic cervical traction can apply closed cervical traction as effectively as manual weight-and-pulley traction in extension spring and cadaveric models.

Summary Of Background Data: Closed cervical traction is used to reduce subaxial cervical spine dislocation injuries and to distract the intervertebral space during cervical spine surgery.
