The anterior articular surface of the calcaneus can be compressed by forceful abduction of the fore part of the foot. Under certain conditions there may also be mid-tarsal subluxation. Whenever compression of his area of the calcaneus is observed on the lateral and oblique roentgenograms, careful study of the anteroposterior projection is desirable to rule out avulsion of the navicular tubercle and derangement of the mid-tarsal joint. Not enough cases have been reported in detail to set forth a definite program of therapy; however, initial treatment should extend beyond simple immobilization. In the case reported open reduction resulted in satisfactory function one year after injury despite roentgenographic evidence of slight joint incongruity.
