[Clinical efficacy analysis of transverse tibial bone transport combined with vacuum drainage for the treatment of diabetic foot ulcer].

OBJECTIVE: To investigate clinical effect of transverse tibial bone transport micro vessels regeneration technology combined with vacuum drainage in treating diabetic foot ulcer.

METHODS: From November 2015 and December 2016, clinical data of 19 diabetic foot ulcer patients treated with transverse tibial bone transport micro vessels regeneration technology combined with vacuum drainage were retrospective analyzed, including 15 males and 4 females aged from 42 to 82 years old with an average of (64.57±7.14) years old;the courses of diabetic ranged was (14.62±6.19) years;12 cases on the left side and 7 cases on the right side;the area of ulcer ranged from 2 cm×3 cm to 8 cm×6 cm. All patients were stage D according to Texas classification, 3 cases were grade 2, 10 cases were grade 3 and 6 cases were grade 4. Ankle-brachial index and Michigan Neuropathy Screening Instrument (MNSI) were used to evaluate recovery of peripheral vessel and nerve before and after operation, the result of angiography and vascular ultrasound were also compared after operation.

RESULTS: Seventeen of 19 patients were followed up from 3 to 13 months with an average of 6.9 months. Seventeen patients' surface wound were healed. Ankle-brachial index was increased from (0.51±0.20) before operation to (0.93±0.18) at 3 months after operation, and had significant difference( t =13.63, P =0.000);MNSI was increased from (4.06±1.36) before operation to(5.76±1.44) at 3 months after operation, and differences were statistically significant ( t =7.31, P =0.000). Postoperative angiography and vascular ultrasound showed satisfied regeneration of micro-vessel and affected foot achieved normal movement and daily life.

CONCLUSIONS: Transverse tibial bone transport micro vessels regeneration technology could reconstruct micro-vessel under lower affected limb, promote recovery of peripheral vessel and nerve, while with vacuum drainage could promote wound healing, has advantages of simple operation, obvious clinical effect, and high success rate of limb-salvage, and is one of ideal treatment for diabetic foot ulcer.
