ABSTRACT:
An improved ambulatory halo device to be worn by a patient for rigid immobilization of the cervical spine has a vest for positionally fixed attachment to the upper torso of the patient, an adjustable framework attached to the vest extending upwardly to adjacent the skull of the patient, and a halo member having a plurality of skull pins adjustably supported on the upper portion of the framework for closely surrounding the skull of the patient. The skull pins are positioned to engage the skull of the patient around the skull above the eyes to rigidly fix the position of the skull and maintain traction on and rigidly fix the position of the cervical spine. The framework is composed of rods and brackets which may be adjustably positioned to positively locate the halo member upon initial attachment to the patient and to permit positional adjustment of the halo member in elevation, anterior/posterior translation and tilt, and rotation about a medial axis of the body of the patient without loss of control of traction on the cervical spine.
