The sternoclavicular joint is the most frequently mobilized non-axial, major joint, but is the least frequently dislocated. Most sternoclavicular dislocations are anterior. When posterior sternoclavicular joint dislocations do occur, they may present with a variety of signs and symptoms, including serious intrathoracic injuries. We discuss the case of a patient with a subacute posterior sternoclavicular dislocation who presented to the emergency department 2 months after being hit in the posterior neck. We also review the signs, symptoms and management of posterior sternoclavicular dislocation and the literature on this topic.

Introduction: Autoregulation is dysfunctional in the injured brain. Increases in intracranial and arterial pressure may therefore result in extension of the primary injury. Rapid sequence intubation (RSI) is a well-known cause of surges in both arterial pressure and intracranial pressure. Neuroprotective agents, namely lidocaine and fentanyl, have the potential to minimize the pressure surges implicated in secondary brain injury. The purpose of this study was to determine the frequency with which neuroprotective agents were used for neuroprotective RSI in the emergency department.
Methods: We conducted a retrospective chart review of all 139 patients intubated in the emergency department of Vancouver General Hospital between March and October 2003. Patients were eligible if there was an indication for neuroprotective agents defined as presumed intracranial pathology and a mean arterial pressure (MAP) > 85 mm Hg. Contraindications to fentanyl included MAP < 85 mm Hg or allergy to fentanyl.
Results: Seventy-seven patients were intubated for primary neurological indications. Indication for intubation included non-traumatic causes (n = 37) (including cerebrovascular accident or intracranial hemorrhage) and closed head injury (n = 40). The mean age (± standard deviation) was 52.3 ± 20.4 years, and 31.4% were female. Fifty-seven (74.0%) patients had indications for neuroprotective agents, without contraindications. When neuroprotective agents were indicated, lidocaine was used in 84.2% (95% confidence interval [CI] 72.6%–91.5%) of patients while fentanyl was used in 33.3% (95%CI 22.4%–46.3%) of patients. Eleven percent of the intubations were performed with a fentanyl dose of ≥ 2 mcg/kg, which is the lower limit considered effective.
Conclusions: Despite the potential benefit of using lidocaine and fentanyl in appropriate patients undergoing neuroprotective RSI in the emergency department, our study identified a significant underutilization of optimal premedication. The identification of barriers to use and the implementation of strategies to optimize use are necessary. -

Objectives: 1) To describe injuries experienced by the male prisoner population in the Kingston, Ontario area, and to compare them with those observed in the general population; and 2) to compare the incidence and patterns of prisoner injuries seen in emergency departments (EDs) before and after the introduction of a prison injury triage system.
Design: A chart review.
Setting: The catchment area surrounding 2 hospital-based EDs in Kingston, Ontario, which includes 8 federal and provincial prisons for adult males.
Observations: Injuries to male prisoners (ages 18-75 years) who were treated in the ED during 1996-98 were compared with injuries to the general male population of the same age range. An on-site emergency care triage system was introduced to area prisons in 1993. Prisoner injuries seen in the ED during 1996-98 were compared with those seen during a similar period prior to the introduction of the triage system (1981-84). Available comparators included patient demographics, disposition, intent and nature of injury, the need for surgery, and lengths of hospital stay.
Results: 148 prisoner injuries were identified for 1996-98. Prisoner injuries seen in the ED were relatively severe when compared with the general male population, as indicated by the higher frequency of fractures (31.8% prisoner vs. 13.4% general, p < 0.001), blunt head injuries (10.1% vs. 2.2%, p < 0.001), hospital admissions (42.6% vs. 4.1%, p < 0.001) and deaths (2.7% vs. 0.6%, p < 0.001). Since the introduction of the triage system there has been a reduction in the rate of prisoner injuries seen in local hospital EDs (6.1/100/yr [before] vs. 1.6/100/yr [after],p < 0.001). There has been an increase in the relative severity of prisoner injuries seen in the EDs as indicated by the increased hospital admission rate (42.6% vs. 22.7%, p < 0.001), increased rate of surgical intervention (27.7% vs. 12.1%, p < 0.001), and increased length of hospital stay (4.0 days vs. 2.1 days, p < 0.05). The mortality rate has remained low and unchanged (0.7% vs. 1.1%, p = 0.99).
Conclusions: The introduction of the new triage system appeared to be associated with a decrease in the total number of ED visits by prisoners. The relative acuity of prisoner injuries seen in the EDs appeared to increase following introduction of the triage system.
