Diagnosis
ReferenceDiagnosis
E. Hitchcock 1848 (Steropezoum)Toes somewhat keel-shaped; the middle and inner ones curved towards the line of direction; the outer one slightly bent from that line. Heel distinct and large; leaving an impression on mud of radiating ridges and furrows, sloping upwards very gradually behind, more abrupt ly before , leavin g a ridge on the track, at least as high as the general surface, between the heel and the toes, which also slope upwards posteriorly. This ridge, however, has usually a depres sion in it, connec ting the heel and the outer toe. But, upon the whole, we infer that the foot arches upwards between the toes and the heel, leaving, however, a slight ridge along its outer part. Bottom of the heel a little elevated above that of the toes.
