Hallux extensus is a persistent dorsiflexion of the first metatarsophalangeal joint. Apart from many other causes, it can also be caused by contracture of the extensor hallucis longus muscle, in our case resulting from surgical treatment of crural fracture. The authors present the case of a 17-year-old soccer player who sustained a fracture of both shin and calf bone during a soccer match and underwent surgical treatment with intramedullary nailing. While compartment syndrome wasn't observed, a postoperative complication in the form of progressive development of a dynamic type of hallux extensus was reported. The reason behind this complication was later found to be the interaction of the osteosynthesis material with the extensor hallucis longus muscle, which led to its scarring and shortening. A Z-lengthening of the musculus extensor hallucis longus tendon was indicated and performed with a good clinical outcome. During surgery, an anatomical variation in the course of the extensor hallucis longus was observed, which had to be taken into account to achieve a successful surgical outcome.

Klíčová slova: cock-up big toe deformity, musculus extensor hallucis longus contracture, Z-lengthening tenotomy, crural fracture complication.
