Coaliciones tarsales, opciones terapéuticas y abordaje artroscópico

Tarsal coalitions, therapeutic options and arthroscopic approach The tarsal coalition or abnormal fusion of 2 or more foot bones is a relative cause, in adolescents, of pain associated with valgus flat foot with some rigidity. The most frequent are calcaneonavicular and talonavicular. The diagnosis is suspect with typical radiological findings and confirmed with computed tomography or magnetic resonance. The treatment is controversial. In adolescents (less than 14-16 years old) with calcaneonavicular or talonavicular coalition with less than 50% of articular surface fusion, the surgical treatment is the resection of the spur, with open or arthroscopic surgery. In older patients, with more extensive articular affection, recurrences or degenerative signs, the double or triple arthrodesis still remains the unique solution.
