Young people who are committed to developing careers in dance typically maintain that they must practice their art every day to meet its demands. Unfortunately, the daily practice of movements that are extreme and repetitive make dancers more susceptible to injury than the population at large. Unlike their fellow athletes in most other sports, dancers seldom experience career-threatening traumatic injuries, but they do manifest a wide range of microtraumatic syndromes. It is a maxim in the field that “if you dance long enough you will sustain injuries.” While the epidemiology of dance injuries still is in the process of being written, in the authors' practice, where dancers are seen with great regularity, the numbers and types of injuries treated can be documented. This article reviews these findings and emphasizes the biomechanics that precipitate the injury, and need to be addressed in formulating strategies for prevention and rehabilitation. The biomechanical approach focuses on one mechanism of injury that should be borne in mind throughout: Most dance injuries result from errors in technique, or the repetitive application of techniques to bodies that are anatomically ill prepared to perform them.
