The strength of tissue against individual sutures in structures used in the repair of inguinal hernia was tested in situ in 19 cadavers. Altogether 465 measurements were made. Three different layers were investigated, and the mean tissue strength to a single suture was recorded as the mean of all means for each preparation and aspect as follows. (1) The superficial layer (external oblique aponeurosis). Superior aspect 5.3 kp, inferior aspect 5.5 kp. (2) Middle layer. Superior aspect (internal abdominal oblique), 5.9 kp; inferior aspect (inferior border of the inguinal ligament), 6.8 kp. (3) Deep layer. Superior aspect (transversalis fascia), 5.3 kp; inferior aspect (ilio-pubic tract), 6.9 kp. In Cooper's ligament the mean holding power of the tissue against a single suture was found to be 9.1 kp. The site of the most medial of the sutures in the superior aspect of the middle layer corresponds to the conjoined tendon, and the mean tissue strength to this suture was 11.0 kp. The findings thus suggest that the strengths of the tissues of the anterior and posterior walls of the inguinal canal are roughly equal. The structures making up the conjoined tendon and Cooper's ligament were strongest, however, and showed tissue strengths nearly twice those of other structures.
在19具尸体上对腹股沟疝修补术中使用的结构中组织对单个缝线的抗拉力进行了原位测试。总共进行了465次测量。研究了三个不同层次，并将单个缝线的平均组织抗拉力记录为每种标本和层面所有平均值的均值，具体如下：(1)表层（腹外斜肌腱膜）。上侧为5.3kp，下侧为5.5kp。(2)中层。上侧（腹内斜肌）为5.9kp；下侧（腹股沟韧带下缘）为6.8kp。(3)深层。上侧（腹横筋膜）为5.3kp；下侧（髂耻束）为6.9kp。在Cooper韧带中，发现组织对单个缝线的平均夹持力为9.1kp。中层上侧最内侧缝线的位置对应联合腱，该缝线的平均组织抗拉力为11.0kp。这些发现表明腹股沟管前后壁组织的抗拉力大致相等。然而，构成联合腱和Cooper韧带的结构最强，其组织抗拉力几乎是其他结构的两倍。
