背景:腰椎滑脱症的治疗目的是重建脊柱序列和椎体稳定性,解除神经压迫,达到永久腰椎融合的作用。目的:探讨腰椎滑脱症患者腰椎融合及植入物内固定后椎体稳定性的恢复。<br> 方法:腰椎滑脱症最常采用Wiltse分型将其分为发育不良性、峡部裂性、退变性、创伤性以及病理性,将腰椎侧位X射线片的上位椎体相对于下位椎体的滑移程度分为5级,根据腰椎滑脱症患者的分型和分级以及患者具体情况选择适宜的治疗方式。<br> 结果与结论:坚强融合内固定,植入物与椎体间是刚性连接,常用来稳定脊柱、矫正畸形,骨融合率较高,减少了假关节形成。动态融合内固定是用弹性材质或微动装置分散坚强内固定负荷传导,减少应力遮挡效应及邻近节段的应力集中。动态非融合内固定能改变脊柱运动节段的负荷传递方式,阻止脊柱运动,预防邻近节段退变,使失稳的腰椎达到其正常状态的活动特性,实现动态重建腰椎序列。峡部关节缺损部位直接修复植骨,适用于青壮年有症状不伴有退行性椎间盘疾病的滑脱患者。腰椎滑脱症选择哪种材料植骨和植骨部位以及哪种入路方法融合和植入物内固定可以得到理想的融合内固定效果一直是学者们争论的焦点,目前尚未达成统一。
揹景:腰椎滑脫癥的治療目的是重建脊柱序列和椎體穩定性,解除神經壓迫,達到永久腰椎融閤的作用。目的:探討腰椎滑脫癥患者腰椎融閤及植入物內固定後椎體穩定性的恢複。<br> 方法:腰椎滑脫癥最常採用Wiltse分型將其分為髮育不良性、峽部裂性、退變性、創傷性以及病理性,將腰椎側位X射線片的上位椎體相對于下位椎體的滑移程度分為5級,根據腰椎滑脫癥患者的分型和分級以及患者具體情況選擇適宜的治療方式。<br> 結果與結論:堅彊融閤內固定,植入物與椎體間是剛性連接,常用來穩定脊柱、矯正畸形,骨融閤率較高,減少瞭假關節形成。動態融閤內固定是用彈性材質或微動裝置分散堅彊內固定負荷傳導,減少應力遮擋效應及鄰近節段的應力集中。動態非融閤內固定能改變脊柱運動節段的負荷傳遞方式,阻止脊柱運動,預防鄰近節段退變,使失穩的腰椎達到其正常狀態的活動特性,實現動態重建腰椎序列。峽部關節缺損部位直接脩複植骨,適用于青壯年有癥狀不伴有退行性椎間盤疾病的滑脫患者。腰椎滑脫癥選擇哪種材料植骨和植骨部位以及哪種入路方法融閤和植入物內固定可以得到理想的融閤內固定效果一直是學者們爭論的焦點,目前尚未達成統一。

BACKGROUND:The purpose of the treatment of lumbar spondylolisthesis is to reconstruct the spine sequence and vertebral stability, relieve nerve compression, and achieve permanent lumbar fusion. <br> OBJECTIVE:To explore the restore of vertebral stability of the lumbar spondylolisthesis patients after lumbar fusion and implant internal fixation. <br> METHODS:The lumbar spondylolisthesis was often divided into dysplastic, isthmic, degenerative, traumatic and pathological with Wiltse classification. The slip degree of upper vertebra relative to lower vertebra on the lumbar X-ray film was divided into five grades, and then the appropriate treatment method was selected according to the classification, grading and specific circumstances of the lumbar spondylolisthesis patients. <br> RESUTLS AND CONCLUSION:The strong fusion and internal fixation and the rigid connection between <br> implants and vertebra are often used to stabilize the spine and correct deformities with high bone fusion rate, thus reducing pseudoarticulation formation. Dynamic fusion and internal fixation can distribute the load conduction of rigid internal fixation with elastic material or micro-devices, thus reducing stress shielding and adjacent segment stress concentration. Dynamic non-fusion and internal fixation can change the load transfer mode of spinal <br> motion segment, inhibit spinal movement and prevent adjacent segment degeneration, in order to make the instable lumbar spine reach its normal activity characteristics, and achieve dynamic reconstruction of lumbar sequence. Lumbar isthmus defects directly repaired with graft is suitable for the young adult with the <br> symptoms of lumbar spondylolisthesis and without degenerative disc disease. There is no consistent option on which materials and position is suitable for graft in the lumbar spondylolisthesis patients, as wel as which methods for fusion and implant internal fixation can achieve ideal effect.
