ABSTRACT
OBJECTIVE: To investigate the application value of the technique of fracture body surface localization film combined with CT volume rendering in the selection of minimally invasive incision for internal fixation of rib fractures. PATIENTS AND METHODS: Clinical data of 55 cases of patients who underwent internal fixation for rib fracture in our hospital from June 2019 to April 2020 were selected. The differences in the accuracy of preset incision, incision length, operation time, intraoperative blood loss, postoperative wound drainage, and postoperative pain score between the group with fracture body surface localization film combined with CT volume rendering (n=32) and the group with traditional localization method (n=23). RESULTS: Compared with traditional localization method, fracture body surface localization film combined with CT volume rendering could improve the accuracy of surgical incision, reduce the operation time, incision length, intraoperative blood loss, postoperative wound drainage, and postoperative pain score (p<0.05). CONCLUSIONS: The application of fracture body surface localization film combined with CT volume rendering has obvious effects on the accurate selection of incision of rib fracture internal fixation, and it is an effective method that is worthy of promotion.

Enhanced glow discharge plasma immersion ion implantation does not require an external plasma source but ion focusing affects the lateral ion fluence uniformity, thereby hampering its use in high-fluence hydrogen ion implantation for thin film transfer and fabrication of silicon-on-insulator. Insertion of a metal ring between the sample stage and glass chamber improves the ion uniformity and reduces the ion fluence non-uniformity as the cathode voltage is raised. Two-dimensional multiple-grid particle-in-cell simulation confirms that the variation of electric field inside the chamber leads to mitigation of the ion focusing phenomenon and the results are corroborated experimentally by hydrogen forward scattering.
