侧隐窝注射胶原酶治疗腰椎间盘突出症定位方法探讨

Localization for collagenase injection through the lateral crypt for lumbar disc herniation

目的探讨定位准确、疗效好的侧隐窝注射胶原酶方法。方法治疗组行胶原酶溶盘术前以体表标记物(用铅号码)定位于压痛点明显的椎间隙,根据X线片及荧光透视法并结合CT进一步定位;对照组未采用铅标记定位方法。结果治疗组优良率和有效率分别为88.3%和95.9%,较对照组分别提高了10.5%和6.7%。结论铅号码标识结合X线片、透视情况及CT进行定位,在侧隐窝注射胶原酶治疗腰椎间盘突出症时定位准确、安全且经济,疗效好,值得临床推广应用。

Objective To find a more reliable and effective localization method for collagenase injection through the lateral crypt for the treatment of lumbar disc herniation. Methods Before collagenase injection for lumbar disc chemonucleolysis, the site with obvious tenderness was labeled with a lead marker on the surface of the intervertebral space, followed by a more accurate localization with the assistance of X-ray, chest fluoroscopy and CT. Results Satisfactory results were achieved in 88.3% of the cases using the new localization method, with an overall improvement rate of 95.9%, which were 10.5% and 6.7% higher than those of cases without using the method. Conclusion Localization with lead markers in combination with X-ray, chest fluoroscopy and CT is more accurate, safe, economic and effective for collagenase injection through the lateral crypt in the treatment of lumbar disc herniation.
