[Melorheostosis of the foot: a case report of a rare entity]

Melorheostosis is a rare bony dysplasia and often recognised just sporadically by chance.

We present a case of a 15 year old girl who presented a melorheostosis of the left foot. After birth there was recognized a shortening and deformity of the 2nd toe on the left foot. Furthermore she had an interphalangeal hallux valgus that displaced the 2nd toe increasingly. Thus in the last years there were more and more difficulties to wear normal shoes. Conservative therapy was not successful. We performed a lengthening extending osteotomy of the 2nd toe (a modified Weil osteotomy) and an Akin osteotomy of the interphalangeal hallux valgus. Since the surgical procedure the patient is out of any complaints.

We demonstrate the radiologic and histologic findings and discuss the relevant literature and possible etiology.
