“…Measurements of the inguinal canal reported by Chrzan et al showed that only approximately 30% of the population fit this average. 6 This corresponds with the findings from our study showing the great (almost 50%) variation in measured groin sizes in the population. Based on these findings, the aim of the present study was to demonstrate the possibility of making individual meshes by a simple modeling and manufacturing process.…”

“…Additionally, as shown in the table, the distance between the pubic tubercle and the anterior superior iliac spine does not vary depending on BMI or sex. 6 Finally, 6 types of meshes, one for each group, were designed and virtually implanted in CT-based computer models. The analysis of the fit of the implant to the patients' anatomic structures showed that the implant had the correct shape, while the size of the implant edge had to be adapted to individual patients, so a minimum of 2 sizes of implants should eventually be designed to maintain a semiaverage shape.…”

Objective The aim of the ILAM (Individualized Laparoscopic Anatomical Mesh) study was to create and implant a fully individualized mesh based on CT scans, taking into account the published body of knowledge about the material and mechanical behavior of the implant for laparoscopic inguinal hernia repair. Summary Background Data The team creating and conducting this study consisted of surgeons and engineers. A specific project was made and divided into 4 phases. Methods The process of development and implantation was divided into 4 milestones: CT scans and modeling based on predefined subgroups, mesh manufacture, certification and clinical evaluation. Results The result of the study was the first individually designed hernia mesh to have been implanted in a human subject. After 12 months of follow-up, no recurrences or other complications were reported. Conclusions The new mesh provides a better anatomic fit to the patients’ inguinal region geometry. Mechanical stability is ensured by the multiple contact points between the implant and the tissues, which generate friction forces. Together with the possibility of shape design (proper overlap), the authors believe that there is no need for mesh fixation. If so, the use of such design meshes can change the guidelines in laparoendoscopic hernia repair in the future.
