Abstract

In recent decades, the fibula flap has become the most popular type of flap used to reconstruct bone defects, especially the mandible due to its quantity and similarity to the damaged bone area. In parallel with research and analysis of the advantages of this type of flap, complications at the flap donor site and how to prevent them are also constantly being reported. Common complications include delayed wound healing, infection, bleeding, graft skin necrosis or late complications such as persistent pain, limited movement of the ankle joint or limited movement due to motor nerve damage. This article presents a special clinical case with rare complications that have not been reported in the medical literature. Materials and methods: Case report and literature review. Results: A 19-year-old male patient underwent surgery to remove ameloblastoma over the right mandibular and reconstruct it with a contralateral fibula free flap. After surgery, the big toe on the left leg gradually flex and folds toward the sole of the foot, causing limited movement. At 3 months after surgery, the big toe was bent at an 80 degree angle, the patient had surgery to lengthen the flexor hallucis longus tendon to improve mobility. Conclusions: Contracture of the tendons after fibula flap harvesting is a rare complication that severely affects toe movement and can be prevented if the surgeon pays attention during surgery.
