Introduction: The dorsal interossei are the abductors of the fingers and the knowledge of its variation help the surgeon in treatment of fractures, claw hand and compartment syndromes. Aim: To note the origin, insertion, pattern of muscle fibres and tendon length of all the dorsal interossei of hand. Materials and Methods: Routinely dissected 30 formalin fixed hand in the Department of Anatomy, KMC, Manipal, were observed for origin, insertion and tendon length and muscle pattern of dorsal interossei. Results: Out of 30 hands, presence of supernumerary muscle was observed in three hands. Presence of three heads of dorsal interossei was noted in one hand. Conclusion: The finding of present study is of importance to surgeons and orthopaedicians during conservative and surgical management of hand deformity. Adequate knowledge of these muscular variations is also important in treatment of fractures, stiff hand, claw hand or tendon transfer.
