ObjectiveTo evaluate the effectiveness of Ilizarov technique-based transverse tibial bone transport on the treatment of severe diabetic foot ulcer (Wagner grades 3 to 5) complicated with systemic inflammatory response syndrome (SIRS).MethodsBetween August 2014 and December 2017, 33 patients with severe diabetic foot and SIRS were treated with Ilizarov technique-based transverse tibial bone transport. There were 27 males and 6 females, with a mean age of 60.6 years (range, 34-79 years). All of them suffered from type 2 diabetes mellitus. The duration of diabetes was 1-28 years (mean, 10 years) and the duration of diabetic foot was 1-12 months (mean, 2.7 months). According to Wagner classification, there were 8 cases in grade 3, 23 cases in grade 4, and 2 cases in grade 5. The wound healing condition was observed after operation, and the limb salvage rate was calculated. The changes in body temperature, heart rate, respiratory rate, white blood cell count, erythrocyte sedimentation rate, and C-reactive protein concentration were assessed. The skin temperature of the dorsum of the foot was measured, and the visual analogue scale (VAS) score was used to evaluate the improvement of foot pain.ResultsAll 33 patients were followed up 3-30 months (mean, 14.1 months). All ulcers healed and the healing time was 3-12 months (mean, 5.3 months); the limb salvage rate was 100%. Postoperative body temperature, heart rate, respiratory rate, white blood cell count, erythrocyte sedimentation rate, and C-reactive protein concentration were significantly lower than those before operation (P<0.05). The skin temperature of the dorsum of the foot was (32.64±2.17)℃ at 1 month after operation, which was significantly improved when compared with preoperative value [(31.28±1.99)℃] (t=0.05, P=0.00); but there was no significant difference in skin temperature compared with healthy side [(32.46±2.10)℃] (t=2.04, P=0.41). The VAS score was 2.4±0.7 at 1 month after operation, which was significantly improved when compared with preoperative score (4.3±0.8) (t=3.10, P=0.00).ConclusionIlizarov technique-based transverse tibial bone transport is an effective way to treat severe diabetic foot complicated with SIRS. It can promote foot ulcer healing and avoid amputations.
ObjectiveTo investigate the effectiveness of tibial transverse transport (TTT) combined with nose ring drain (NRD) in the treatment of severe diabetic foot ulcer.MethodsThe clinical data of 60 patients with severe diabetic foot (Wagner grade 3 or 4) ulcer who were admitted between April 2017 and August 2020 and met the selection criteria were retrospectively analyzed. Among them, 30 cases were treated with TTT combined with NRD (TTT+NRD group), and 30 cases were treated with TTT (TTT group). There was no significant difference in gender, age, diabetes duration, preoperative glycated hemoglobin, comorbidities, wound area, and duration, side, and grade of diabetic foot (P>0.05). The wound healing time, wound healing rate, amputation rate, recurrence rate, duration of antibiotic therapy, hospital stay, number of hospitalizations, and number of operations were recoreded and compared between the two groups.ResultsNo obvious surgical complications occurred in the two groups. Patients in both groups were followed up 3-13 months, with an average of 5.7 months. The duration of antibiotic therapy and hospital stay in the TTT+NRD group were significantly shorter than those in the TTT group (P<0.05). There was no significant difference in wound healing time, wound healing rate, number of hospitalizations, and number of operations between the two groups (P>0.05). During follow-up, there was no recurrence of ulcer in the TTT+NRD group while 2 recurrent cases (6.7%) in the TTT group. The difference in recurrence rate was not significant (P=0.492). One case (3.3%) in the TTT+NRD group underwent amputation due to acute lower extremity vascular embolism, and 1 case (3.3%) in the TTT group underwent amputation due to secondary necrosis. The difference in amputation rate was not significant between the two groups (P=1.000).ConclusionTTT combined with NRD is an effective method for the treatment of severe diabetic foot ulcers with deep infections or relatively closed cavities or sinuses. It can shorten the time of antibiotic use and the length of hospitalization; and the NRD has a good drainage effect without obvious comorbidities, procedure and the postoperative care are simple and easy to obtain materials.
