C2 Type II Odontoid Fracture

PATIENT INFO: An 86 year old female presented after falling and suffering a fracture

SUMMARY: Patient elected for a surgical fusion rather than an external orthosis. The patient underwent placement of C1-2 screws (Harms fusion). After placement of the screws, and prior to application of the rods, an intraoperative MR image was obtained to assess the cervical spinal cord. Metal artifact prevented an accurate assessment of screw placement in relation to bone; however, the cervical cord was clearly visible, the vertebral arteries were visually patent, and the reduction of the odontoid process could be measured. Surgery concluded with placement of the rods and allograft bone. Postoperative x-rays showed good placement of the instrumentation.
