Chronic Progressive Dislocation of the Talo-navicular Joint.

Jensen (1963) reported a case of so-called bilateral dislocation of the talus in a woman of sixty-four. The etiology of the lesion was not determined. The patient had had no trouble with her feet until she was forty-nine, when she began to get pain and valgus deformity. The pain ceased after six months but the deformities became progressively more severe. Jensen stated that he had not found references to similar cases in the literature. Two patients with this deformity have been attending the Royal Orthopaedic Hospital, Birmingham. Before Jensen published his case I had been unable to find references to the lesion in the literature. The present cases are considered to be specially worth recording because there are radiographs showing progression of the condition in each case over a period of eighteen years.
