[Observation on the curative effect of fibula transverse transport technique in the treatment of diabetic foot ulcer].

To investigate the clinical effect of fibula transverse transport technique in the treatment of diabetic foot ulcer. Nine patients (7 males and 2 females) with diabetic foot ulcer were treated with fibula transverse transport technique from September 2017 to September 2020. The mean age was (55±9) years (ranged from 43 to 66 years). In terms of Wagner classification, 2 cases were in grade 2, 5 cases were in grade 3, and the other 2 cases were in grade 4. All of the cases involved ischemic ulcers or ischemic-nerve ulcers. The transcutaneous oxygen pressure (TcPO) of the dorsal foot of the affected limb was measured, with the ulcer healing and TcPO changes recorded at follow-up. All the 9 patients were followed up for (23±12) months (3 to 38 months). It was found that all patients with foot ulcers were cured within (4.2±1.9) months (2 to 8 months), and all the patients obtained limb salvage. Besides, there was no serious complications occurred, such as skin necrosis and needle tract infection. Before the operation, the TcPO of the affected foot was (28.6±3.8) mmHg(1 mmHg=0.133 kPa), while it was (35.0±5.6) mmHg three months after operation (<0.05). The technique of fibula transverse transport can effectively improve the microcirculation function of diabetic foot, and it can promote the healing of the ulcer with few complications.
