Radiography showed calcification at the insertion of the tendon and magnetic resonance imaging showed tendinosis and partial injury of the tendon at the insertion of the calcaneal tendon (Fig. 1).
Isolation of the long flexor of the hallux (black curved arrow) and long accessory flexor (white arrow on left side) with different tunnels and sheaths. Above this, the pushed-back calcaneal tendon (white arrow at upper right) shows severe intratendinous degeneration.
