Diagnosis
ReferenceDiagnosis
J. Y. Kim et al. 2012Tetradactyl bird tracks show prominent, postero medially directed hallux impressions comprising about one-third of total track length. Hypex between digits III and IV is more anteriorly situated than hypex between digits II and III, with the tendency for development of asymmetric, semipalmate web that is more strongly developed between digits III and IV. Digit divarication between II and IV averages at least 110–120◦ wide. Digit pad impressions are variable but sometimes show a 2-3-4 phalangeal formula corresponding to digits II, III, and IV. Step is typically short with a strong tendency towards inward rotation.
