<unk>  is found in both children and adults, but there is a difference between children and adults with<unk> . Adults<unk>  traumatic event The prevalence of<unk> es in North American adults in the 1900s was about 1.2%.<unk>  is most commonly found in young healthy adults, from ages 14 to 63 years old, with 50% of patients between 19 and 34 years old. 89% of<unk>  patients are male. The rate of<unk>  has been increasing. Children Incidence of OBPP OBPP, also known as obstetrical<unk><unk>  palsy, occurs primarily in young children at a rate of 0.38 to 1.56 per 1000 live births depending on the type of care and the average birth weight of infants in different regions of the world. For example, a study in the United States showed and incidence of OBPP of about 1.51 cases per 1000 live births, in a Canadian study, the incidence was between 0.5 and 3<unk> es per 1000 live births, a Dutch study reported an incidence of 4.6 per 1000 live births. The risk of<unk>  at birth is highest for infants weighing more than 4.5 kg at birth born to diabetic women. Type of delivery also affects the risk of<unk> .<unk>  risks for newborns are increased with gained birth weight, birth delivery where a vacuum is assisted, and not being able to handle glucose. Traumatic<unk> es Motorcycles and<unk> <unk>  has shown to occur in 44% to 70% of traumatic<unk> es, such as motorcycle accidents, sporting activities, or workplace accidents. With 22% being motorcycle<unk> es and about 4.2% having<unk>  damage. People who have accidents with riding motorcycles and snowmobiles have higher risks of getting a<unk>  and with ihg-injury<unk> es such as motorcycle accidents, root avulsion from the spinal cord is the most common pattern of<unk>  (~72% prevalence of at least 1 root avulsion) which requires surgery to reanimate the arm.
