Comparative StudyThe management of "asymptomatic" epidural hematomas. A prospective study.
Standard neurosurgical management mandates prompt evacuation of all epidural hematomas to obtain a low incidence of mortality and morbidity. This dogma has recently been challenged. A number of authors have suggested that in selected cases small and moderate epidural hematomas may be managed conservatively with a normal outcome and without risk to the patient. ⋯ None of the patients suffered neurological sequelae attributable to this management protocol. It was concluded that patients with a small epidural hematoma, a fracture overlaying a major vessel or major sinus, and/or who are diagnosed less than 6 hours after trauma are at risk of subsequent deterioration and may require evacuation. Conversely, patients without these risk factors may be managed conservatively with repeat CT and careful neurological observation, because of the low risk of delayed deterioration.

Comparative StudyA comparison of the Minerva and halo jackets for stabilization of the cervical spine.
The motion at each intervertebral level permitted by the halo jacket and the thermoplastic Minerva body jacket was compared in 10 ambulatory patients with an unstable cervical spine. The thermoplastic Minerva body jacket is a new lightweight modification of a Minerva jacket which is fabricated from Polyform (a splinting material made of a polyester polycaprolactone) and Polycushion (a closed-cell foam for padding). Each patient served as his/her own control. ⋯ This difference is attributable to the "snaking phenomenon" encountered with halo jacket immobilization and should be taken into account when considering an external splint for an unstable cervical spine. The thermoplastic Minerva body jacket also offered a substantial improvement in comfort for the patient over that experienced in the halo jacket. The apparent advantage with respect to stability and comfort of the thermoplastic Minerva body jacket over the halo jacket suggests that the former device is the orthosis of choice for ambulatory stabilization of most patients with an unstable posttraumatic cervical spine injury.
