During my sabbatical, I rode my bike 3300 miles from Washington, DC, to Seattle, WA, in order to engage in dialog with people along the northern tier of America's heartland. Through informal and candid conversations with >100 people, I gained insights into attitudes and opinions about the Patient Protection and Affordable Care Act (Obamacare). The comments were overwhelmingly negative. In this reflective essay, I share some of the conversations I had and the insights I gained from this remarkable journey across our beautiful country...

Laryngeal fracture is a rare condition with potential life-long implications related to airway patency, voice quality, and swallowing. Rarity of the condition leads to lack of consensus on the most suitable way to manage this injury. The mode of injury can be prevented by strict legislation on the roads. We report a case of a 28-year-old Indian male who sustained a comminuted displaced fracture of the thyroid cartilage with disruption of anterior commissure due to blunt trauma caused by the metallic side rod of a ladder projecting from the rear of a vehicle in front of the bike on which he was riding...

Injuries to the acromioclavicular (AC) joint are becoming common with contact sports and bike accidents. It is well known that in AC dislocations, the first structure to fail is the AC capsule followed by the trapezoid and conoid ligaments. The function of these ligaments must be restored to restore the anatomy and physiology of the AC joint to get the best results. Until now, no technique has emerged as the gold standard for restoration of the AC joint anatomy and function. In our technique, the stress is on recreating the anatomy to make it more individualized based on individual variations...

OBJECTIVES: In 2014, 726 bicyclists were killed and an additional 50,000 were injured in crashes with motor vehicles. The number of cyclists in the United States is increasing, and as a result there has been a call for more bike lanes. We examined the difference in the severity of injury of bicyclists involved in motor vehicle crashes when riding in the traffic lane compared with riding in a bike lane or on a paved shoulder. We also controlled for other safety factors, including alcohol use, travel speed, posted speed, helmet usage, and lighting conditions to determine their impact on bicyclist safety...

INTRODUCTION: Public bike share users have low prevalence of helmet use, and few public bike share systems make helmets available. In summer 2016, a public bike share system launched in Vancouver, BC. Each bicycle is equipped with a free helmet, in response to BC's all-ages compulsory helmet law. This study assessed the prevalence of helmet use among adult cyclists on personal and public bicycles in Vancouver. METHODS: A survey of adult cyclists (age estimated at ≥16 years) at five screen line sites and at 15 public bike share docking stations was conducted...

REVIEW
Andrew Ja Holland, Soundappan Sv Soundappan
Trauma and injury continue to be common in children and remain an important cause of mortality and morbidity. Legislation mandating the use of helmets for all cyclists appears to have been effective in reducing the incidence and severity of head and facial injuries, with no clear evidence of a reduction in cycling usage or activity. Straddle injuries, whilst uncommon and generally minor, require careful clinical assessment as they may be associated with urethral trauma. Quad bikes remain highly dangerous with continuing reports of deaths in child riders due to their inherent lack of stability: a ban on their use by children would seem the most effective solution...
