Abstract: Background: This study is to evaluate and compare the radiological and functional outcome of the management of acute thoracolumbar burst fractures with and without transpedicular hydroxyapatite & tricalcium phosphate (triosite) grafting following short segment pedical screw fixation. Methods: This study was conducted in 39 consecutive cases of short segment fixation with or without transpedicular augmentation and comparision by using ASIA impairment scale, Cobbs angle and the low - back outcome scale of Greenough and Fraser1. Results: The difference in both the groups in terms of neurological recovery and the Greenough low back outcome score at the time of follow up found to be statistically insignificant. Transpedicular augmentation increases the mean operative duration by 25 minutes. Kyphotic deformity remains the same in both groups. mean loss of correction was higher in patients without transpedicular augmentation. Conclusion: Transpedicular hydroxyapatite grafting with short segment pedical screw fixation could provide reliable neurologic improvement in patients with incomplete neurologic deficit and could prevent the development of kyphosis.
