From: Ectopic gas in the fibular graft after anterior cervical corpectomy and fusion
A 54-year-old man underwent anterior cervical corpectomy and fusion due to cervical disc herniation (Group IV). One-level corpectomy and a fibula graft were performed. The computed tomography image showed ectopic gas (arrow) in the fibular graft 3 months after surgery (A). The gas disappeared 6 months after surgery (B) and 2 years after surgery (C) with sufficient bone fusion
