Hallux valgus and hallux rigidus are the two most frequent pathologies around the MTP-1-joint. Hallux valgus is more common in the general population, and hallux rigidus is more common among athlethes. Stiffness of the MTP-1-joint is one of the most dreaded complications after hallux surgery. In the case of recreational sports, hallux valgus and rigidus can be treated in the same way as in the general population. Professional athletes require a different treatment. Surgery should be delayed as long as possible because there is a high risk of potentially career-ending scarring of the joint. For hallux valgus in professional athletes, the aim is to convert a decompensated bunion into a compensated one. This can usually be achieved with a simple chevron osteotomy, which has a low risk of scarring and complications. More extensive surgery should be delayed until the end of the competitive career. In the case of hallux rigidus, a simple cheilectomie, possibly with an additional closing wedge osteotomy of the proximal phalanx and/or shorting of the distal first metatarsal, is sufficient. More extensive surgery, again, ought to be delayed until the end of the competitive career. To decrease the risk of scarring, minimal invasive surgical techniques should be used more frequently for treatment of hallux valgus and rigidus.
