Abstract
Background: The anatomical variations of muscles and nerves in the forearm and wrist are common. Gantzer’s muscle is the accessory belly in the flexor compartment of forearm frequently arises from the medial epicondyle and inserted in to the one of the deep muscle of forearm.
Material and Methods: Present study was conducted in department of anatomy, Institute of medical science, Banaras Hindu university, Varanasi, UP and Indira Gandhi institute of medical sciences, Patna, Bihar. The present study consist of 48 upper limb.
Result: Incidence of accessory muscle belly was detected in 20 (41.66) out of 48 upper limb. 16 of these cases have two accessory belly and 4 have single muscle belly. All are arises from medial epicondyle of humerus below the flexor digitorum superficialis and inserted in to flexor digitorum profundus.
Conclusion: Knowledge of accessory muscle belly is important not only for anatomist but also for surgeon. Variations of muscle belly kept in mind while approaching the forearm for flexor digitorum superficialis tendon transfer and other surgical procedures in the flexor compartment of forearm and hand.
Keywords: Flexor digitorum superficialis, Gantzer’s muscle.
