The aim of this study was to assess the result of Atlantal lateral mass and axis pedicle screw fixation for the treatment of unstable C2 odontoid fracture. We investigated the clinia records of 20 patients suffered from unstable C2 odontoid fracture whom received an Atlantal lateral mass and axis pedicle screw fixation at Phu Tho General hospital from 1/2012 to 12/2015. | JOURNAL OF MEDICAL RESEARCH SURGERY RESULT ASSESSMENT OF C1 LATERAL MASS AND C2 PEDICLE SCREW FIXATION IN TREATING UNSTABLE C2 ODONTOID/ DENS FRACTURE IN PHU THO GENERAL HOSPITAL Son Nguyen Van1, Toan Do Thi Thanh2, Ngoc Nguyen Huy1, Hoat Luu Ngoc2 1 Phu Tho General Hospital, Vietnam; 2Hanoi Medical University, Vietnam Superior cervical spinal lesions account for 25% of cervical spinal lesion. Due to the special structure of superior cervical spine and the diversity of anatomical lesions, various non-surgical treatment methods such as Mini Verve powder, Halo frame, continuous traction, as well as surgical methods such as occipital splints, screwing through joints, C1 - C2 posterior arch binding, screwing through the odontoid process.have been applied to treat these lesions.Comparing these techniques, the fixation of the C1 lateral mass and C2 pedicle with polyaxial screws has many advantages and has been widely applied in recent years. The aim of this study was to assess the result of Atlantal lateral mass and axis pedicle screw fixation for the treatment of unstable C2 odontoid fracture. We investigated the clinia records of 20 patients suffered from unstable C2 odontoid fracture whom received an Atlantal lateral mass and axis pedicle screw fixation at Phu Tho General hospital from 1/2012 to 12/2015. Of all the patients, no intraoperative complications were observed. The average recovery time was 15 days, as being judged by clinical systems after surgery without major neurological complications and wound infection. We concluded that the C1 lateral mass and C2 pedicle screw fixation for treatment of unstable odontoid fracture is a suitable option for these conditions with a high success rate and few complications.
