Review Meta Analysis
The effect of low-intensity pulsed ultrasound therapy on time to fracture healing: a meta-analysis.
The effect of low-intensity ultrasonography on fracture healing is controversial, and current management of fractures does not generally involve the use of ultrasound therapy. We describe a systematic review and meta-analysis of randomized controlled trials of low-intensity pulsed ultrasound therapy for healing of fractures. ⋯ There is evidence from randomized trials that low-intensity pulsed ultrasound treatment may significantly reduce the time to fracture healing for fractures treated nonoperatively. There does not appear to be any additional benefit to ultrasound treatment following intramedullary nailing with prior reaming. Larger trials are needed to resolve this issue.

Review Case Reports
The legal duty of physicians and hospitals to provide emergency care.
Accessibility of hospital emergency services has been an issue of increasing concern and was recently brought into public focus in Ontario by the tragic death of Joshua Fleuelling, whose ambulance was redirected from the nearest hospital. As will be reviewed, the limited case law has identified a legal duty for physicians and hospitals to provide treatment to people in need of emergency care, a duty that should be considered when formulating hospital policies. The impact of this duty of care on the existing standard of medical practice will be considered.
