Free fibula and flap graft for reconstruction all the first metatarsal bone / 中华显微外科杂志

ABSTRACT

Objective To evaluate the clinical effects of free fibula and flap grafts on the repair of all the first metatarsal bone at one stage.Methods There were 9 cases with the first metatarsal bone defect from Janurary 2003 to December 2009 that treated with free vascularized fibular bone and free vascularized flap at one stage.In which 6 cases reconstructed at the primary stage and 3 cases reconstructed at the second stage.Seven cases reconstructed by free vascularized fibular combined with ALTPF,two cases reconstructed by free vascularized fibular combined with TAPF.The free vascularized fibular and flap restored the first metatarsal bone and the soft tissue defects respectively.Vascular anastomosis was the artery of flap anastomosis with anterior tibial artery and the vein of the flap anastomosis with great saphenous vein,the peroneal artery and accompany vein anastomosis with artery and vein of the flap.Results The grafted tissues survived smoothly in 8 cases,vein crisis happened in I case and the ALTPF necrosis after blood vessels expedition.So the TAPF was changed to cover the soft defect and survived smoothly.Followiy-up were done from 6 to 36 months in 9 cases.There were no ulcer on flaps and no fracture again,the fibulas had been bone healing.Evaluated by Maryland standards,six cases were excellent,two cases were fine,one case was good.Conclusion The fibula combined flap grafts provide a relatively better alternative to repair the first metatarsal bone compound tissue defects at one stage.In addition,the procedure decreased frequency of operations and short the course of treatment.Sensory function reconstruction of fibula flaps should be given full attention.As fine function of the reconstructed foot,it is a effective method for reconstruction the burdened area of the foot.
