              Surgical Treatment of thoracolumbar burst fracture with posterior short segment pedicle fixation could provide initial correction of kyphosis , but it has been associated with loss of reduction and instrument failure. This study evaluates the clinical relevance of short segment pedicle fixation with intermediate screws at fracture level. 21 patients were assessed in this retrospective study. All patients were followed for a minimum 36 months
(X= 38 ; SD 17 ). Preoperative mean Anterior vertebral height compression (AVHC) and local kyphosis angle
(KA) were 40 % ( SD 20 % )and 16° (SD 12°) ,respectively.
              The mean correction of AVHC and kyphosis were 24% (SD 15% ) and 14° (SD 8° ) respectively. The mean loss of correction at the last follow up was
1.1 % (SD 3.2 % ), and 2.2° (SD 2.8°) for AVHC and KA, respectively. The loss of correction of kyphosis was significant (p< .001 ) ,whereas of AVCH was not significant (p = 0.135 ). Despite there was significant loss of the correction of local kyphosis, the final KA at the latest follow up compared with the preoperative value was still significantly improved (p< .001). There was no evidence of instrument failure or neurologic deterioration in this series.
              It is concluded that short segment pedicle fixation with intermediate screw at fracture level provides a significant correction of local kyphosis, The initial correction was well maintained and there was no serious complication.
