Rib fractures usually occur with blunt trauma to the chest, often due to significant external force (such as stopping a car suddenly, being hit by a baseball bat, or falling from a height).
Fractures are a disruption of the integrity of a bone. Symptoms of fractures include pain, swelling, hemorrhage, crepitus, deformation, and dysfunction of the limb.
The goal is to tightly match the edges of the wound, preventing them from turning in and creating closed spaces in the wound, minimizing the tension of each individual suture, leaving a minimum of foreign material in the subcutaneous tissue.
Motion sickness is a symptom complex typically involving nausea, often accompanied by vague abdominal discomfort, vomiting, dizziness, and related symptoms; it is caused by repeated angular and linear accelerations and decelerations.
Altitude sickness includes several related syndromes caused by decreased available O2 in the air at high altitudes. Acute mountain sickness (AMS), the mildest form, presents with headache along with one or more systemic manifestations.
Frostbite is damage to tissue caused by freezing. Initial manifestations can be deceptively benign. The skin may be white or blistered, numb; thawing causes severe pain.
