Transitional vertebra

Transitional vertebrae and accessory vertebrae are defined as variant anatomy. While they may remain entirely asymptomatic, it is possible that they could cause pain by lack of mobility, soft tissue irritation, or nerve compression anytime now or in the future. Understanding your medical history and preventing irritation to these potentially susceptible areas is invaluable. The understanding of the variant anatomy is also important when symptoms occur and essential if surgery is planned.
