title: Extensor tendons injuries.
abstract: Extensor mechanism injuries are frequently encountered in athletes and can lead to permanent disability or deformity if not promptly and properly treated. This article reviews basic anatomy, and then discusses mallet finger injuries, boutonniere deformity, and sagittal band rupture. Once treatment has begun, return to sport is highly variable because of the varied needs of each athlete and where they fall on the spectrum of disease. As such, each athlete must be carefully evaluated and closely followed to ensure a safe, prompt, and judicious return to athletic pursuits.
