A 3.5\u2005mm virtual trocar was inserted via the Kiss-in method; an axis-radius-aligned coordinate system enabled precise measurement of dTRA, dTMN, dTF, dTP, aTTR, aSTR, aNAT, and aNFT. A \u201crisky zone\u201d (\u22640\u2005mm from RA\/MN) was defined and analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>No statistically significant differences were found between most parameters of the two portals, except for dTP and dTF. The data for dTF, dTP, aTTR in the VRMC portal, and aSTR in the VRRC portal showed statistically significant differences between genders. Female dTP values at both joints were less than the trocar's length of 45\u2005mm. Male dTP values in the VRRC portal exceeded 45\u2005mm in 22 cases (68.75%), and in the VRMC portal, 10 cases (31.25%). The frequency of the \u201crisky zone\u201d was significantly higher in the VRRC portals.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This imaging simulation study supports the theoretical feasibility of the Kiss-in method for establishing radial volar portals. The simulation results suggest potential safety benefits for the VRRC portal and indicate that the standard trocar length may be more adequate for female patients in this cohort. The determination of aTTR and aSTR has guiding significance for the practical application of the Kiss-in method.<\/jats:p>\n
