So its validity, long-term effectiveness, and bone transport standards are need further research.

To evaluate the effectiveness of the nose ring drain (NRD) in treatment of severe diabetic foot infection.

The clinical data of 35 patients with severe diabetic foot infection who were treated with NRD between June 2017 and June 2019 were analyzed retrospectively. There were 24 males and 11 females with an average age of 54.5 years (range, 28-82 years). All of them were type 2 diabetic patients. The diabetes duration was 3-20 years, with an average of 9.4 years. The diabetic foot duration was 4 months to 2 years, with an average of 1.16 years. There were 16 cases of left foot and 19 cases of right foot. According to Wagner’s grading, there were 11 cases of grade 2, 20 cases of grade 3, and 4 cases of grade 4, all of which were moderate and severe infection of diabetic foot wound. Postoperative wounds were treated with “nibble-like” debridement until the patient’s epidermis regenerated and healed. During the treatment process, the indexes of bacterial culture type of wound secretions, duration of antibiotind healing and regeneration without skin grafting.

The NRD is a simple operation for treatment of severe diabetic foot infection, which can effectively control wound infections and promote wound healing and regeneration without skin grafting.

To explore the causes and management of the complications in diabetic foot treated with tibial transverse transport (TTT).

Between September 2015 and September 2019, 196 patients with diabetic foot were treated with TTT. ABR238901 There were 109 males and 87 females, with an average age of 67.6 years (range, 45-86 years). According to Wagner’s classification, there were 124 cases of grade 3, 62 cases of grade 4, and 10 cases of grade 5; the course of disease was 1-12 months, with an average of 2.6 months. All patients underwent the minimally invasive tibial osteotomy. The osteotomy site was the middle and lower tibia in 62 cases and the middle and upper tibia in 134 cases. The area of osteotomy was 20 cm

in 83 cases and 7.5 cm

in 113 cases. The osteotomy block was moved back and forth once in 92 cases and twice in 104 cases. The complications were recorded, including secondary fracture at tibial osteotomy, skin necrosis in osteotomy area, and pin tract infection.

Among 196 patients, 41 cases (20.9%) had comective method to treat diabetic foot, but there are complications such as secondary fracture at tibial osteotomy, skin necrosis in osteotomy area, and pin tract infection during transport. Preoperative evaluation of indication, standardization of osteotomy mode, size and position of osteotomy block, establishment of individualized removal plan, and strengthening of pin track nursing after operation can effectively reduce complications.

To study the effectiveness of tibial transverse transport combined with the antibiotics embedded bone cement in the treatment of chronic infection of foot and ankle with lower extremity ischemic diseases.

A retrospective analysis was performed on 28 patients with ischemic diseases of lower extremities associated with chronic foot and ankle infection who were treated with tibial transverse transport combined with antibiotic bone cement between August 2015 and October 2019. There were 22 males and 6 females, with an average age of 65.6 years (range, 41-86 years). There were 25 cases of diabetic foot, 2 cases of arteriosclerosis obliterans, and 1 case of thromboangiitis obliterans. The course of infection ranged from 1 to 27 years, with an average of 14.9 years. The healing condition and time of foot and ankle in all patients were recorded and compared, and the Wagner grading and WIFi (W lower extremity wound classification; I ischemic classification; Fi foot infection classification) grading were compared bperation. Two patients with lower extremity arteriosclerosis obliterans had foot and ankle healing at 16 and 18 months after operation, respectively.

Tibial transverse transport combined with the antibiotics embedded bone cement is effective in treating chronic infection of foot and ankle with lower extremity ischemic diseases.

To evaluate the treatment results of Ilizarov microcirculation reconstruction technique for chronic wounds in the post-traumatic ischemia limbs.

Between January 2016 and July 2019, 7 cases of chronic wounds in the post-traumatic ischemia limbs were treated. There were 5 males and 2 females, with an average age of 42.4 years (range, 29-66 years). The duration of the wound ranged from 1 month to 2 years (mean, 7.7 months). The wounds located in the leg (3 cases) or in the foot and ankle (4 cases). The wound sizes ranged from 4.0 cm×2.2 cm to 12.0 cm×7.1 cm. There were 1 case of tibial varus, 3 cases of equinovarus, 1 case of scleroderma, and 2 cases of Volkmann’s ischemic contracture. After debridement, external fixators were used for tibial transverse transport, or correction of tibial varus and correction of equinovarus.

All patients were followed up 8-20 months, with an average of 13 months. The infection of wound surface was all controlled in 7 cases and the granulation tissue grew well; the wound surface healed directly in 5 cases and healed after skin grafting in 2 cases, and the wound healing time was 1-3 months (mean, 1.7 months). During the follow-up, there was no recurrence of the wound. Six cases of limb deformity were corrected.

For the chronic wounds in the post-traumatic ischemia limbs, Ilizarov microcirculation reconstruction technique can effectively improve local circulation and facilitate the fresh granule growth and wound healing.
