Reconstruction of the Pretibial Soft Tissue Lesion after Chronic Tibia Osteomyelitis using Anterolateral Thigh Perforator Flap

The purpose of this study was to present the clinical result of anterolateral thigh free flap for pretibial soft tissue lesion after chronic tibia osteomyelitis. From December 2006 to September 2008, Five patients were included in our study. 4 of 5 were superficial or localized types of chronic tibia osteomyelitis, based on the classification of Cierny and Mader. Average age at the surgery was 45 years, three were males and two were females. All had a history of chronic tibia osteomyelitis and subsequent pretbial soft tissue lesions coming from previous operations or pus drainage. Pretibial soft tissue defects included small ulcers, fibrotic, bruisable soft tissue and small bony exposures, but not large-sized bony exposures nor active pus discharge. After complete debridement of large sized pretibial soft tissue lesions and decortication of anterior tibial cortical dead bone, anterolateral thigh free flap was applied to cover remained large pretibial soft tissue defect and to prevent the recurrence of infection. All flaps survived and provided satisfactory coverage of soft tissue defect on pretibial region for 16 months' mean follow up period. No patients has had recurrence of osteomyelitis. Anterolateral thigh free flap could be recommend for large sized pretibial soft tissue defect of supreficial or localized types of chronic tibia osteomyelitis after through debridement.
