Applied Anatomy of Inguinal Region and its Clinical Significance

Objective:To provide the anatomic foundmation data for clinical repair of inguinal heria.Methods:The inguinal structure of 30 adult corpses(20 males,10 females)observed and fixed by formaldehyde was measured with set square,protractor and vernier caliper.Results:The average length of inguinal ligament was(11.6±0.9)cm,and the width was(0.6±0.2)cm.The length of inguinal canal was(4.6±0.6)cm and that of inguinal falx was(2.1±0.8)cm.The posterior wall of inguinal canal could be divided two closely-linked fascia and formed an egg-shaped area of(2.8±0.8)cm in length and(1.3±0.39)cm in width.Conclusion:These observation can supply anatomical basis and useful data for the repair of hernias in clinic.The deep layer of transverse fascia was weaker than superficial layer in these corpses.To strengthen and reconstruct the posterior wall of inguinal canal was the key point in the clinical repair of inguinal hernia.
