A Study Of Variations In Iliohypogastric And Ilioinguinal Nerves In Human Adults

ABSTRACT

Introduction: Lumbar plexus is one of the main nervous pathways supplying the lower limb which is bound toshow variations. Surgeons should be aware of these variations to avoid possible injuries to the structure andtheir consequences. This study was conducted to observe the formation of Iliohypogastric nerve and IlioinguinalnerveMaterial and methods: Dissection of 40 bilateral lumbar plexuses from formalin fixed adult human cadaversprocured from department of anatomy JJMMC Davangere.Results: Many significant variations were found in the anatomy of the iliohypogastric and ilioinguinal nerve.Conclusion: Knowledge of the variations in the branching pattern and formation of the lumbar plexus is essentialto prevent nerve injury during routine surgical procedures like inguinal hernia surgery, low transverse incisionof gynecological procedures
