Posterior osteotomy and long-segment internal fixation for the treatment of senile thoracolumbar kyphotic deformity / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To explore the therapeutic effects of posterior osteotomy and long-segment internal fixation in the treatment of senile thoracolumbar kyphotic deformity and provide the reference for operative treatment.</p><p><b>METHODS</b>From April 2007 to April 2010, 19 older patients with thoracolumbar kyphotic deformity were respectively analyzed. There were 12 males and 7 females with an average age of 62 years (ranged, 58 to 74 years). Among patients, 11 cases were old fracture, 3 cases were ankylosing spondylitis, and 5 cases were old spinal tuberculosis. According to preoperative Frankel classification, 12 cases were grade E, 4 cases were grade D, 2 cases were C and 1 case was grade B. All patients were treated by posterior osteotomy and long-segment internal fixation and followed up above 1 year. VAS score preoperative, 2 weeks and 1 year after operation, Cobb's angle,n erve function and complication were observed.</p><p><b>RESULTS</b>VAS score preoperative, 2 weeks and 1 year after operation separately was (7.0 +/- 1.2),(1.1 +/= .7) and (1.3 +/- .8); while Cobb's angle separately was (44.1 +/- .9), (10.9 +/- .1) and (11.5 +/- .8); there was significant difference in VAS score and Cobb's angle between preoperative and 2 weeks after operation (P < 0.05) w hile no significant difference between 2 weeks and 1 year after operation (P > 0.05). Eighteen cases met the standard of osseous fusion, 1 case occurred nonunion, but not looseness 1 year after operation. Nerve function 3 cases changed grade E from 4 cases with grade D, 2 cases with grade C changed to grade D, 1 case with grade B changed to grade</p><p><b>CONCLUSION</b>Posterior osteotomy and long-segment internal fixation for the treatment of senile thoracolumbar kyphotic deformity can receive a good short-time effects.</p>
