[The effectiveness of Ilizarov technique-based transverse tibial bone transport on treatment of severe diabetic foots complicated with systemic inflammation response syndrome].

Objective: To 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).

Methods: Between 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.

Results: All 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).

Conclusion : Ilizarov 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.
