ABSTRACT This retrospective study aimed to evaluate the clinical efficacy of double flap tibial transverse transport (dTTT) in the treatment of Wagner grade 3–4 diabetic foot ulcers (DFUs) and to assess its impact on peripheral nerve function in the affected limb. A total of 25 patients with DFUs who underwent dTTT at our institution were included. Baseline data were collected, and patients were systematically followed at 1, 3, 6 and 12 months postoperatively. Primary outcome measures included wound healing status, postoperative complications, microcirculatory indicators and nerve conduction parameters. All bone transport sites healed successfully, with no major complications observed except for one patient who died from COVID‐19. At 12 months postoperatively, significant improvements were noted in foot skin temperature, transcutaneous oxygen partial pressure and the ankle‐brachial index (all p < 0.001). Additionally, motor nerve conduction velocities of the posterior tibial and common peroneal nerves increased significantly ( p < 0.001), and corresponding compound muscle action potential amplitudes rose to 4.91 ± 0.14 mV and 4.68 ± 0.29 mV, respectively ( p < 0.001). These findings suggest that dTTT not only facilitates wound healing by improving local microcirculation but also enhances peripheral nerve function, offering a promising therapeutic approach for improving long‐term outcomes and quality of life in patients with advanced DFUs.
