Halo traction device.

A thorough understanding of the underlying diseases and of the halo pin traction device will allow for appropriate treatment of complications. Consultation or referral to the neurosurgeon is advised to prevent serious sequelae. The following points should be remembered: 1. Pins should only be tightened during the first 24-hour period after application. 2. Pin infection is treated by local wound care in most cases. 3. CT scan cannot completely exclude the presence of an abscess secondary to artifact, but MRI may be compatible with the newer devices. 4. Pin penetration of the inner table of the skull requires admission. 5. Any suspected loss of alignment or reduction of the cervical spine requires C-spine immobilization. 5. Nasotracheal or fiberoptic intubation or emergent cricothyroidotomy should be used if orotracheal intubation proves difficult due to the device. 7. The anterior portion of the vest is removable for cardiopulmonary resuscitation without compromising the stability of the device.
