Posterior ankle impingement syndrome in dancers — a short-term follow-up after operative treatment

Under the extreme stress of ballet dancing, the anatomical proximity of the bony structures involved can lead to the so‐called `Nutcracker phenomenon' and be responsible for the development of a fatigue fracture of a processus posterior tali [16,17].…”
