ABSTRACT

Objective To explore the application of various forms of anterolateral thigh flap in lower extremity and ankle amputation with extensive skin and soft tissue defect reconstruction.Methods From September 2011 to December 2015,26 cases of lower extremity and ankle amputation with extensive skin and soft tissue defect reconstruction (included 20 male patients and 6 female patients) were admitted,the age ranged from 22 to 61 years old (38.6 ± 4.5).Among these cases,10 cases received flow-through anterolateral thigh flap,16 cases used chimeric anterolateral thigh flap with vastus lateralis thigh muscle flap,15 flaps were thinned in one-staged,5 flaps were harvested in double-paddled form.The flap size ranged from 10 cm × 6 cm to 28 cm × 12 cm.The donor site was closed directly in all cases.Results All flaps and replanted extremities survived uneventfully.All patients were followed up for 8 to 30 months with satisfied esthetic and functional results in reconstructed foot and ankle,the texture of flaps was good,no bulky was noted and no second revision was needed.No local ulcer happened and regained protective sensation.Only linear scar left in the donor sites,no hernia occurred.Conclusions Various forms of anterolateral thigh flap is the effective choice in lower extremity and ankle amputation with extensive skin and soft tissue defect reconstruction.
