OBJECTIVE: To evaluate the clinical outcome of surgical management for post-traumatic thoracolumbar @entity85 with @entity5 . METHODS: From March 2007 to May 2010, 17 @entity1 with post-traumatic thoracolumbar kyphotic @entity85 were admitted. The preoperative Cobb angle was 41  -62  (52.5     6.4  ). Sagittal balance was evaluated by the standing lateral films measuring the C7 plumb line distance (C7 PLD) from the posterior superior corner of S1. The C7 PLD was 18-58 (41.2   12.4) mm in the sagittal plane. The preoperative @entity717 index (ODI) was 42-50 (45.7   2.7), and the average preoperative visual analogue scale (VAS) was 8-10 (8.8   0.7). The American @entity3510 Association (ASIA) impairment scale was used to assess the @entity51 , and grade C in 1 @entity1 , grade D in 7 and grade E in 9 @entity1 . The operation time, @entity190 , complications, post-operative Cobb angle, ODI and VAS score at the follow-up were collected and analyzed. RESULTS: The average duration of postoperative follow-up was 24-53 (34.5   7.1) months. The operation time was 180-400 (287.1   65.9) min, with an @entity190 of 350-1 300 (838.2   276.4) mL. The postoperative kyphotic angle was 3  -12   (6.1     3.0  ), and it was 7.5     2.6   at the final follow-up evaluation. The postoperative C7PLD was (3.6   3.9) mm and it was (3.4   2.3) mm at the final follow-up evaluation. Postoperatively, the ASIA impairment scale was grade D in 4 and grade E in 13 @entity1 . At the final follow-up ODI and VAS were reduced to an average of 5.2   2.4 and 2.4   1.0, respectively. @entity5173 was found in 2 @entity1 , deep wound @entity281 in 1, and @entity9 in 2. All the complications were relieved after conservative medical therapy. One @entity1 received additional surgery at postoperative 12 weeks due to breakage of posterior implants. Another screw pullout case was treated with reinsertion of larger screws at postoperative 4 months. Solid fusion was confirmed by plain film and CT scan in all @entity1 within 1 year after the surgery. CONCLUSION: Single-staged posterior transpedicular limited osteotomies is safe and effective to correct post-traumatic thoracolumbar @entity85 .
