As delay in diagnosing unstable cervical spine injuries unnecessarily exposes patients to risk of neurologic injury, it is often recommended that complex radiologic investigations be performed on alert patients with neck pain, tenderness, or neurologic deficit despite normal plain radiographs. The optimal investigation of patients unable to reliably provide such information is less clear. How many X-rays are enough to clear the cervical spine? In order to answer this question, a retrospective review of 775 motor vehicle crash (MVC) victims was conducted. ⋯ Lateral radiographic visualization of the complete cervical spine (including a swimmer's view as required) had a sensitivity of 83% and a specificity of 97%. The addition of open mouth (OM) and anteroposterior (AP) views detected all patients with unstable fractures except one man with a head injury who was unable to provide clinical clues to the diagnosis, but who suffered no additional harm as a result. A single lateral X-ray of the cervical spine is inadequate to exclude cervical spine injury in severely traumatized patients and the addition of OM and AP views still failed to identify unstable fractures in one of 385 patients in this series of MVC victims with GCS less than 15.(ABSTRACT TRUNCATED AT 250 WORDS)

Ninety-two most severely injured patients--with injuries to at least four body regions with a mean ISS of 39--were examined at the outpatient clinic 5 to 20 years after the trauma. In addition, nine patients were interviewed by phone, thus 92.6% of the patients still alive were contacted. ⋯ Only seven patients needed constant medication because of their injuries. We conclude that the treatment of even the most severely injured patients with multiple injuries is certainly worth the effort.

Comparative Study
Trauma outcome analysis of two Canadian centres using the TRISS method.
In this retrospective study, the TRISS method of trauma care analysis is used to compare trauma care at the Hamilton General Hospital (HGH) and the Ottawa Civic Hospital (OCH) with the standards reported in the Major Trauma Outcome Study (MTOS). A total of 274 adult patients with multiple-system injuries were studied; their demographic data, Trauma Scores (TS) on arrival to the Emergency Room, and Injury Severity Scores (ISS) were reviewed. The TRISS scores and Z and M statistics were then calculated. ⋯ Most patients (63.5%) were transferred from regional hospitals. The Z and M statistics were 1.20 and 0.56, respectively. We conclude that the survival statistics of trauma patients treated at both centres are comparable to those of trauma patients in the MTOS.

Case Reports
Pediatric Chance fractures: association with intra-abdominal injuries and seatbelt use.
Seven cases of Chance fractures of the spine in children are presented, with their association to intra-abdominal injuries secondary to seatbelt use. A discussion and review of the literature suggest an increasing frequency of this particular injury with a high association given the clinical sign known as the "seatbelt sign." Also reviewed is the association of intra-abdominal injuries secondary to seatbelt restraints, and particular attention is paid to the concurrence of intra-abdominal injury with Chance fractures of the spine. The unique features of the pediatric anatomy in relation to the design of the adult seat restraint as it relates to the vertebral fracture and intra-abdominal injuries are noted. A review of the literature discusses the development of a classification for this flexion-distraction type of vertebral injury, and supports our experience of the increasing frequency of these particular injuries with increasing seatbelt use.

Percutaneous tracheostomy is increasingly being used for patients needing prolonged ventilatory support. The purpose of this study was to assess the feasibility of widespread application of endoscopic guided percutaneous tracheostomy. Sixty-one consecutive ICU patients requiring prolonged mechanical ventilation underwent bedside endoscopic guided percutaneous tracheostomy. ⋯ There was a 50% reduction in cost when compared to operative tracheostomy. Percutaneous tracheostomy is a simple, safe, cost-effective bedside procedure for critically ill ventilator-dependent patients. Endoscopic guidance appears to increase the safety of this procedure and may prevent complications of pneumothorax, subcutaneous emphysema, and paratracheal false passage previously reported with blinded percutaneous methods.
