Introduction[edit | edit source]

The ankle is a crucial joint to acknowledge in the context of dance injuries because it is the connection between the leg and the foot that establishes lower limb stability. It is one of the most commonly injured body areas in dance.[1] Incidences of injury to the ankle-foot complex scale from 27% to 49% of total injuries in ballet, modern, flamenco, and tap dancers.[1][2] Dancer’s tendonitis is also referred to as Flexor Hallucis Longus tendonitis which is an overuse injury in which repetitive plantarflexion and dorsiflexion (pointing and flexing) of the foot results in inflammation of the FHL tendon.

In dancers, injury to the FHL is usually provoked by the recurrent movement caused by changing position from a plié position to a relevé position. (Plié is a French term meaning to bend, relevé, is a ballet term meaning “raised.” The term relevé explains the action when a dancer rises up on their toes).[3] This movement of action produces a force that is ten times the dancer's body weight. Bio-mechanically, a restricted plantarflexion movement may lead to a prolonged pronated foot position when pushing off during the Propulsion Phase which can lead to FHL tendonitis.

The Flexor Hallucis Longus (FHL) has been also called as the ‘Achilles of the foot’ due to its unique role controlling midfoot pronation and supination, and its physiological and mechanical properties, which permit it to act as a powerful convertor of force from the rear foot all the way through to the big toe. Due to its anatomical arrangement and its unique actions, it is a muscle-tendon unit that can often become injured in athletic populations.
