Introduction: Tendon variation of Extensor Digitorum muscle was observed in a 48yr old male formalin fixed cadaver, during the dissection at Anatomy Dissection hall. The tendons of Extensor Digitorum muscle shows anatomical variation most often and its knowledge is important to assess the diseased and traumatized hand. Incidences have shown that tendons of ED may be variably deficient but more often they are doubled or even tripled in one or more digits. The incidences of doubling are higher in index finger or in the middle finger. Very rarely a slip of tendon passes to the thumb. Methods: Regular dissection at Anatomy Dissection Hall. Result & Conclusion: In this present case in left forearm, the origin of muscle was normal but its tendon divides into five proximal to wrist which pass through a common synovial sheath deep to the Extensor Retinaculum. The extra tendon is in between 4th and 5th digit. The right forearm does not show any anatomical variation. This type of variation is rarely found. This particular variation is important for clinical perspective. This case study is useful for surgeons performing Tendon Graft Operations or Tenoplasty.
