Description
Summary:Vertebral osteochondroma is a rare entity. It presents with varied complaints ranging from palpable mass to myeloradiculopathy. En bloc excision is the gold standard treatment option for symptomatic patients. Real-time intraoperative navigation has increased the accuracy and safety of tumor excision. We report a case of cervical subaxial osteochondroma with myelo-radiculopathy, treated with excision, and monosegmental fusion under O-arm-based real-time navigation. A 32-year-old male presented with complaints of axial neck pain with the right upper limb radiculopathy for 18 months. On examination, signs of myelopathy were identified without sensory-motor deficit. Magnetic resonance imaging and computed tomography scans were suggestive of solitary C6 osteochondroma compressing spinalcord. O-arm navigated en-bloc tumor excision with C5 hemilaminectomy and monosegmental fusion was done. The use of O-arm navigation aids in accurate intraoperative en bloc excision without any residual tumor and with better safety.
