Diagnosis
ReferenceDiagnosis
S. de Valais and R. N. Melchor 2008Footprints showing four digits, three of which (II to IV) are directed forward and larger, the fourth (I), directed backward, spur-like and short. The inter- digital angles between digits II and III and between digits III and IV are commonly less than 700. The axis of digit I does not correspond with that of digit III, the interdigital angle between digits I and II being smaller than that between digits I and IV. When present, phalangeal pad marks displaying the relation I: 2, II:c2o, nIIsI:i3d,eIVr:4t.h Webbingabsent. (modified from Sarjeant and Langston, 1994:8.
