The aim of this study was to evaluate the effectiveness and safety of free corticoperiosteal medial femoral condyle (MFC) flap for ankle, hindfoot and midfoot reconstruction in patients with recalcitrant nonunion.
Patients who underwent ankle and foot reconstruction using the MFC flap at our clinic were recruited for assessment of the union rate, time to union and functional outcome. Furthermore, a clinical and radiological examination of the donor knee was performed using both computed tomography and magnetic resonance imaging.
Thirteen patients with a mean follow-up time of 2.5 years were included; 10 of them had a previously failed ankle and foot arthrodesis. Union was achieved in 11 patients in an average time of 10 months after MFC flap surgery. Donor site morbidity was minor with no radiological evidence for soft tissue or bone complication.
MFC flaps are a useful and safe reconstructive tool and may be considered after failed ankle and foot arthrodesis.
本研究旨在评估游离皮质骨膜内侧股骨髁（MFC）皮瓣在治疗难治性骨不连的踝关节、后足和中足重建中的效果和安全性。
在我们的诊所，采用 MFC 皮瓣对踝关节和足部进行重建的患者被招募来评估愈合率、愈合时间和功能结果。此外，对供膝进行了计算机断层扫描和磁共振成像的临床和影像学检查。
纳入了 13 名平均随访时间为 2.5 年的患者，其中 10 名患者先前有踝关节和足部融合失败的病史。在 MFC 皮瓣手术后平均 10 个月，11 名患者达到了愈合。供区并发症轻微，无软组织或骨并发症的影像学证据。
MFC 皮瓣是一种有用且安全的重建工具，可在踝关节和足部融合失败后考虑使用。
