The proximal fibular free flap - an ideal material for reconstructing distal radius defect after Giant tumor cell resection. A case report

Giant cell tumors (GCT) of the distal end of radius are relatively common tumors, representing approximately 5% of all primary bone tumors. It is the third most common location for GCT following distal femur and proximal tibia. In general, treatment includes thorough tumor excision, reconstruction of the defect, and wrist joint rehabilitation. The proximal fibular free flap is an ideal material for distal radius reconstruction after giant cell tumor excision. We present a case of a 57-year-old female, admitted to the hospital due to painful and limited proper wrist movement. Based on X-ray and Magnetic resonance imaging (MRI) images and histopathology findings, the patient was diagnosed with a stage 3 giant cell tumor of the distal radius. The patient underwent a one-step surgery of tumor excision and distal radius reconstruction by a vascularized proximal fibular free flap. 2 years follow-up post-surgery showed that the patient had no pain of the wrist, improved wrist joint function, no sign of recurrence, and good flap vitality and the knee joint remains normal. In conclusion, the surgery was successful with no further prolonged pain, improvement of the wrist joint function and overall improvement of the patient quality of life.
