leucopus specimens two independent lateral digital extensor muscles were found, they were between the craniolateral antebrachial muscles These extensors are called the extensor digiti IV proprius muscle (extensor digiti quarti proprius) and extensor digiti V proprius muscle (extensor digiti quinti proprius), they are between the extensor digitorum communis muscle and extensor carpi ulnaris muscle.

The embryological explanation for such an anomaly can be explained by the fact that the precursor extensor muscle mass differentiates mainly into three bundle--the superficial extensor digitorum communis, extensor carpi ulnaris and the extensor digiti quinti proprius and the anomalies related to the extensor muscle are commonly due to an early developmental defect related to the developing extensor sheet of the forearm (6).
