Methods： The study was conducted fromAugust 2010 to December 2011 and cases were selected from the out- patient department of Postgraduate Institute of Medical Education and Research, India. The patients were in the age group of 30 to 50 years. All patients were operated via both anterior and posterior approaches. Results： During the immediate postoperative period, five （83.33%） patients had normal neurological status. One （16.67%） patient who had C5-C6 subluxation developed neu- rological deficit with sensory loss below C6 level and motor power of 2/5 in the lower limb and 3/5 in the upper limb below C6 level. Conclusion： There is no role of skull traction in ne- glected distractive flexion injuries to cervical spine delayed for more than 3 weeks. Posterior followed by anterior ap- proach saves much time. If both approaches are to be done in the same sitting, there is no need for instrumentation posteriorly. But if staged procedure is planed, posterior sta- bilization is recommended, as there is a risk of deterioration in neurological status.展开更多
