Deep Circumflex Iliac Artery Osteoseptocutaneous Flap as a Reconstruction Method for Distal Radius Recurrent Giant Cell Tumour in the Case of a Bilateral Peroneal Magna Artery: An Eight-Year Follow-Up

A vascularized fibula flap is an option to reconstruct osseous and soft tissue defects involving distal radius malignancy with massive soft tissue involvement. This reconstruction method is a strong anatomical construct for wrist arthrodesis and flexible septocutaneous tissue for closure. However, in rare cases of bilateral peroneal magna artery, a vascularized fibula flap is not a suitable option given its potential risk of limb ischemia. We report the case of a 35-year-old lady with recurrent distal radius giant cell tumor with bilateral peroneal magna artery, whereby a vascularized fibula flap is not a reconstruction option for the distal radius. In this case, we opted to use the deep circumflex iliac artery (DCIA) flap to reconstruct the defect. This case highlights the importance of clinical assessment and Doppler evaluation before harvesting a vascularized fibula graft and the DCIA flap as an alternative option for reconstruction of the distal radius with a good functional outcome eight years post-operation.
