Abstract:
Objective:To investigate the effect and indications of pedicled myocutaneous flap and modified Masquelet technique in the repair of diabetic soft tissue and tibial bone defects.Methods:From January, 2017 to October, 2019, data of surgical treatment of 20 patients with diabetic soft tissue and tibial bone defects were retrospectively studied. The detects were repaired by the pedicled myocutaneous flap combined with modified Masquelet technique. There were 13 males and 7 females aged 40 to 65(average 51) years old. Preoperative ultrasound and CTA had confirmed that there was no occlusion in anterior and posterior tibial arteries. After debridement, the bone defect was 4-9 cm in length and the soft tissue defect was 3 cm×6 cm to 7 cm×10 cm. The initial antibiotic loaded bone cement filling of the bone and soft tissue defects was carried out. Then at 7-10 days later, had the bone cement placed earlier removed the remaining spaces of bone defect were again filled by antibiotic loaded bone cement. Meanwhile, the pedicled myocutaneous flap was transferred to repair the wound. The second stage of Masquelet technique was performed later, with an interval of 8-12(mean 9) weeks. The healing of wound and bone defect, and the complications were recorded. At 12 months after the surgery, the healing and appearance of the flap were evaluated by the standard proposed by Zhang Hao, and the functional recovery of the adjacent joint was evaluated by Johner-Wruhs standard. The treatment was considered successful when the symptoms were disappeared and no recurrence occurred.Results:All patients entered 13 to 28 months of follow-up, 20 months in average. The healing time for bone defect was 6-11 (average 9.0) months. All myocutaneous flaps survived with 18 flaps healed in the stage one and 2 delayed healing. Nine flaps appeared almost normal and 11 shown bloating. Seventeen flaps were found with partial sensation and 3 without sensation at all. The temperature of 7 flaps was found normal and 13 were slightly lower. Fourteen donor site scars were mild and 6 were obvious. The overall curative effect was satisfactory. Two patients had recurred infection. The rates of excellent and good functional recovery, infection control and success of treatment were at 90%(18/20) for each.Conclusion:Pedicled myocutaneous flap combined with modified Masquelet technique can repair diabetic soft tissue and tibial bone defects. It has a good therapeutic effect for short and medium terms.
