Abstract:
Objective To explore the efficacy and safety of digital design based on 3D printing technology in internal fixation of distal tibial comminuted fracture. Methods 148 patients with unilateral comminuted fracture of distal tibia who received surgical treatment in Xuzhou Cancer Hospital from February 2019 to February 2022 were selected as the study subjects; Randomized numerical table method was used to divide the patients into observation group (74 cases) and control group (74 cases). The clinical data of the two groups were analyzed. Randomized walking model was used to evaluate the improvement of clinical indicators of patients with two surgical treatment methods. Results Compared with the control group, the clinical treatment excellent rate, American Orthopedic Foot and Ankle Association (AOFAS) score and Barthel index of patients in the observation group were higher 6 months after operation (P<0.05), the operation time and fracture healing time were shorter (P<0.05), the intraoperative bleeding was less (P<0.05), and the visual analog score of pain (VAS) of patients in 6 months after operation, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and IL-8 water in 24 hours after operation were lower (P<0.05). The evaluation results of random walking model showed that the improvement of surgical indicators, postoperative joint function, pain, quality of life and inflammatory reaction in the observation group were better than those in the control group. The rate of complications in the observation group at 6 months after operation was no significant difference between the two groups (P>0.05). Conclusion The digitally designed internal fixation operation based on 3D printing technology can effectively improve the surgical indicators, postoperative joint function, pain, quality of life and inflammatory reaction of comminuted fracture of distal tibia patients, and the clinical treatment rate is high, while the rate of complications is low.
