Introduction: Flexor digitorum profundus (FDP) muscle is the muscles of anterior compartments of the forearm with the most frequent anatomical variations. Macalister reported the variations in FDP. The incidences of variation are observed mainly in the number of heads of proximal attachment, though the variation in the tendon of distal attachment is comparatively rare. Methods: A 48-year-old male formalin preserved cadaver, finely dissected at dissection hall. Results: Normally the FDP muscle insert with four tendons. In this present case, the origin of FDP muscle was normal, but its insertion was by five separate tendons variate musculo-tendon which was found arises from FDP muscle in the mid of the 2nd and 3rd tendon with its fibers again dividing and going with them. Macalister reported many variations regarding this muscle but this type of variation is less commonly found. Conclusion: This particular variation is important for a clinical perspective as this extra musculo tendon may cause entrapment syndrome of the median nerve and also for the surgeon to be careful while performing tenoplasty.
