摘要：Introduction: A rare type of variation of extensor muscles on the dorsum of hand is extensor digitorum brevis manus (EDBM).It is a small muscle rarely present on the dorsum of the hand which can be misinterpreted a pathological mass on the dorsum of the hand. Aim: Aim of the present cadaveric study is to observe the incidence, anatomical morphology of EDBM and to study its phylogenetic significance. Material and Methods: Present study was conducted on 32 adult human cadaveric hands of which 24 were of male and 8 were of female cadavers. Results: The EDBM was observed in one incidence (3.1%) of the specimens. EDBM was found to be between the tendons of extensor digitorum for index and middle fingers. It was of Anatomical variant type I. Conclusion: The knowledge of incidence and morphology of EDBM is of greater relevance in clinical practice to rule out any pathological mass on the dorsum of the hand.
