The Effect of Local Halo Pin Care Reagents on Cranial Radial Compressive Stress (When Tightening Halo Pins)
Stephen H. Liu, MD
Thomas R. Lunsford, MSE, CO
Robert L. Waters, MD
The halo fixation device is used widely for treating traumatic injury to the cervical spine. Complications can be minimized by retightening, increasing torque and practicing local pin care. The coefficient of friction at the halo ring/pin thread inte...
