摘要
目的:为第5腰椎横突肥大综合征提供解剖学基础。方法:用第5腰椎、骶骨各390块,测量第5腰椎横突、椎间孔的上下径和前后径。结果:第5腰椎横突正常上下径为13.3±2.6mm,前后径12.4±2.5mm。第5腰椎肥大的横突上下径为20.9±2.4mm,前后径30.9±3.3mm。第5腰椎横突肥大L5～S1椎间孔的前孔,左侧:上下径11.5±4.3mm,前后径10.5±2.7mm;右侧:上下径10.2±4.5mm,前后径9.6±3.0mm。结论:第5腰椎横突肥大,可引起L5～S1椎间孔的前孔狭窄,累及第5腰神经为腰腿痛的原因之一。当影响下肢运动时可行横突的肥大部分切除术。
Objective: To supply anatomic basis for the hypertrophy of the transverse process of L5. Method: The vertical height and the asgittal width of the 5th lumber interveltebral foramen are measured on 780 pieces of the 5th lumber vertebras and sacrums. Results:The normal vertical height of the 5th lumbera is 13.3 ±2.6mm(x ± s);the asgittal width 12.4± 2.5mm. The height of the hypertrophic transverse process of L5 is 20.9±2.4mm;the width 30.9 ±3.3mm.The height of the left interveltebral foramen is 14.5 ±4.3mm,the width 10. 5 ±2. 7mm; the height of the right interveltebral foramen is 10. 2 ± 4. 5mm, the width 9. 6 ± 3. 0mm. Conclusion:The hypertrophy of the transverse process of L5 can lead to the stenosis of part of interertebral foramen,which may oppress the anterior ramus of the Sth lunbemerve. When it influenses the motion of the limbers, the transversectomy may be done on the hypertrophic part of the transverse process.
