Abstract
INTRODUCTION: Trauma to spine is one of the grave injuries. They cause infinite morbidity and disability to the patient. Lately consensus is evolving across the world for stabilization of unstable spines with fusion and instrumentation even though most authors agree that neurological recovery is independent of treatment modality. Objectives of this study are to evaluate effectiveness of spinal stabilization with pedicular instrumentation in the management of thoraco-lumbar fractures to restore structural stability, early ambulation and improving neurological status of the patient Material and Methods: During the period from October 2009 to September 2010, 33 cases of thoraco-lumbar spine fractures were treated operatively with posterior decompression and pedicular screw instrumentation. Of these, 3 cases were lost to follow up. Hence the results of 30 cases were evaluated. All patients were treated by posterior decompression and pedicular screw instrumentation. Neurological and radiological parameters were assessed during serial follow-ups. OBSERVATION AND RESULTS: The mean duration of follow-up was 11 months. Of the 30 patients 24 showed neurological improvement by at least 1 grade and average grade of improvement was 1.5 grades. Mean pre-operative sagittal angle (SA) was 19.9 degrees and sagittal index (SI) was 0.54. Mean post-operative SA was 9.3 degrees and SI was 0.72. Mean SA and SI during the final follow-up were 10.9 degrees and 0.69 respectively. DISCUSSION AND CONCLUSION: Neurological recovery and maintenance of radiological correction in our study were comparable to other studies. The results in our short series of 30 cases have been encouraging. But there is need for more cases and longer follow-ups to come to categorical conclusion.
