Abstract:
[Objective]To evaluate the clinical value of surgical treatment of multiple thoracolumbar spinal fractures by pedicle screw/rod Instrumentation system.[Method]Ninteen cases of male 14 and femal 5 of multiple injuries involving thoracic and lumbar spine were surgically treated through anterior approach by open reduction,selective vertebral canal decompression,internal fixation with pedicle screw/Rod spine instrumentation,and followed by anterior lateral bone graft fusion according to complex classification system 19 cases,Ba.m1T_(11) 1 cases,Ba.m.p2T_(11) 2 cases,Ba.m1T_(12) 1 cases,Ba.m.p2T_(12) 1cases,Ba.m.p3T_(12) 1cases,Ba.m1_L 4 cases,Ba.m.p2L_1 3cases,Fa.m.p3(T_(12),L_1) 2cases,Sa.m.p3L_2 1cases,Ba.m.p1L_2 1 cases.[Result]All cases were followed up form 6 to 15 months averageing 10.5 months.No implant failure and late kyphosis deformity was observed.The average vertebra height was improved from preoperative 48.14% to postoperative 92.14%.The postoperative neurological function in two cases of complete spina lcord injuries and 11 incomplete spina lcord injuries were improved according to JOA criterion.Astable bone fusion according to radiological criteria was achieved in call cases postoperatively,and progressive compression did not occur.[Conclusion]Pedicle screw/rod instrumentation system can achieve effective reduction for the fractured vertebrae and simultaneously restore spine stability on the basis of adequate vertebral canal decompression.Posterior spine instrumentation is an ideal choice for surgical treatment of thoracolumbar unstable fractures with or without spinal cord dysfunction.
