Peroneal spastic flatfoot syndrome.
Tarsal coalitions are not the sole cause of peroneal spastic flatfoot, and any irritative lesion in the peritalar area can induce protective contraction of any or all of the muscles bridging the peritalar joints. True muscular peroneal spasm has been shown to be present on a clinical basis in this entity where tarsal coalitions are not present. Neoplasm should be included in the differential diagnosis of the rigid flatfoot deformity.
