Brief summary
Introduction. Currently, there is a tendency towards an increase in the number of amputations of the lower extremities, including due to armed conflicts. Therefore, it is extremely important to develop additive technologies that open up new opportunities for a personalized approach to creating culturally acceptable sleeves. Objective: comparative analysis of the effectiveness of primary prosthetics of patients with amputation at the level of the lower leg using various additive technologies - FDM printer and PDI Squirt Shape 3D printer Methods. The study was conducted from November 2024 to February 2025. The criteria for including patients in the study: local injuries of traumatic, inflammatory or vascular genesis, the prescription of which did not exceed 12 weeks, in the absence of defects in the leg stump after amputation, preservation of soft tissue trophism, consistency of the postoperative scar, the absence of decompensated forms of chronic diseases and concomitant conditions that threaten the lives of patients. Prosthetics were performed using digital modeling and 3D printing of cultural receiving sleeves. Rehabilitation efficacy was assessed on the basis of biomechanical gait parameters at two stages of dynamic control (immediately after prosthetics and after 8 weeks), as well as on the time characteristics of the prosthesis. The study results were processed statistically using Microsoft Excel and Biostatistics spreadsheets. Results. The study included 10 patients divided into two equal groups. The results showed that prosthetics using PDI Squirt Shape 3D Printer provided higher walking speed (by 7.4%), better gait rhythm (rhythm coefficient 0.95 ± 0.04, p ≥ 0.05) and significantly reduced prosthesis manufacturing time compared to classical FDM printing (on average 4.5 times, p ≥ 0.05). Conclusions. It was concluded that the use of PDI Squirt Shape technology in clinical practice is promising as a tool to improve the quality of prosthetics and accelerate the rehabilitation of patients with post-amputation defects of the lower leg. Due to the fact that our study was performed on a small number of patients, this problem should be further studied.
