钉棒治疗胸腰椎爆裂型骨折

目的]评价钉棒系统治疗胸腰椎多节段脊柱骨折的临床疗效。方法]19例多节段胸腰椎骨折患者，其中男14例，女5例；骨折分类采用目前综合分类法，本组病例中Ba．ml T11 1例，Ba．m．p2T11 2例，Ba．ml T12 1例，Ba．m．p2T12 3例，Ba．m，p3T12 1例，Ba．ml L1 4例，Ba．m．p2 L1 3例，Fa．m．p3（T12，L1）2例，Sa．m．03 L2 1例，Ba．m．p1 L2 1例。均采用前路切开复位，选择性椎管减压，钉棒系统内固定及前外侧植骨融合进行手术治疗。结果]全组病例随访6～15个月，平均10．5个月，未发现内固定物松动、离断，无继发性脊柱后凸畸形加重，椎体高度由术前平均48．14％恢复至术后平均92．14％，2例完全性及11例不完全性脊髓损伤者，术前术后采用JOA评分显示，脊髓神经功能获改善。术后随访X线片显示所有病例植骨块均已融合，无植骨块塌陷及高度丢失现象。结论]前外侧入路椎管减压充分，钉棒系统能有效复位椎体骨折，重建脊柱稳定性，是胸腰椎不稳定性骨折合并脊髓神经损伤手术的理想选择。

Surgical treatment of multiple thoracolumbar spinal fractures by pedicle screw/rod instrumentation system

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.
