One Stage Microsurgical Reconstruction with Chimeric Flap for Salvaging a Complex Hand Injuries

Abstract

Hand injuries, involving extensor tendon with carpal bone loss are catastrophic events. Reconstructive surgeons typically face difficulties in minimizing the number of operations, recovery period and restoring its functions with an acceptable aesthetic outcome. However, chimeric flap, which consists of multiple composite flaps from one of the sources of main vascular system is a promising option for reconstruction. This paper presents a case of near-amputated degloving injury over the extensor tendon with carpal bone loss on left hand due to road traffic accidents. The patient had a hand reconstruction with chimeric flap consisted of free fasciocutaneous anterolateral thigh flap and vascularized osteomyocutaneous iliac bone graft with tensor fascia lata from the lateral circumflex femoral vascular system. As a result, the hand functioned well and appeared aesthetically acceptable. Thus, this surgery is an effective option in recovering and reconstructing a complex and traumatic hand injury that involved multiple composite tissue defects.
