ARVINIUS, C et al. Dislocation of the proximal hallux interphalangeal joint with interposition of a sesamoid bone: a blibliographic review. Acta ortop. mex [online]. 2017, vol.31, n.1, pp.35-39. ISSN 2306-4102.

The irreducible dislocation of the hallux interphalangeal joint is an infrequent condition and only a few cases have been described. It presents as dorsal dislocation with interposition of the sesamoid bone, which has the possibility of being radiologically undetectable. We present the case of a 29 year-old patient who, after a sports trauma sustained a hallux interphalangeal dislocation that went unnoticed for eight days. Since, closed reduction was not possible, as occurred in several cases reported in the literature, open reduction was performed through a dorsal incision. Based on a bibliographic review, it is possible to state that there are several treatment options and multiple approaches, and that these lesions usually have a good prognosis.
