The Flexor Hallucis Longus (FHL) tendon is Harry in the “Tom, Dick, and Harry” grouping of extrinsic foot muscle tendons that pass through the tarsal tunnel. The FHL is responsible for great toe flexion and it assists with plantar flexion of the ankle. While not often inflamed in isolation in the general population or in the athletic population at large, the FHL can very easily become injured in dancers. Most frequently, FHL tendinopathy is caused by repetitive strain, but indirect or direct injury and irritation can result from acute trauma.
