【摘要】：目的：通過對頸椎側(cè)位X線片多項(xiàng)解剖學(xué)參數(shù)的測量及統(tǒng)計(jì)分析,了解不同頸椎節(jié)段的參數(shù)變化趨勢及差異,為頸人工椎間盤假體設(shè)計(jì)提供理論數(shù)據(jù)。方法：選取山東大學(xué)齊魯醫(yī)院健康查體門診行頸椎X線檢查的健康查體者40例,均拍攝直立中立位頸椎側(cè)位X線片。在影像工作站平臺(tái)中分別測量椎體正中矢狀徑及中央高度,各椎間隙前緣、中央及后緣高度,椎體上、下終板的矢狀徑長度,椎體上、下終板角度,椎體上、下終板曲率半徑,椎體上關(guān)節(jié)突角。測量長度精確至0.0lmm,測量角度精確至0.1。,并對測量數(shù)據(jù)進(jìn)行統(tǒng)計(jì)分析。 結(jié)果：1、椎體正中矢狀徑：C7C6C3C4C5, C3、C4、C5與C7間差異有統(tǒng)計(jì)學(xué)意義,余椎體間比較無統(tǒng)計(jì)學(xué)差異。 2、椎體中央高度：C7C3C4C5C6, C3、C4、C5、C6與C7間差異有統(tǒng)計(jì)學(xué)意義,余椎體間比較無統(tǒng)計(jì)學(xué)差異。 3、椎間隙高度：各椎間隙的中央高度前緣高度后緣高度,差異有統(tǒng)計(jì)學(xué)意義。各椎間隙中央高度間相互比較,C2/3、C3/4、C4/5、C5/6間隙間差異無統(tǒng)計(jì)學(xué)意義；其與C6/7間隙間比較,差異有統(tǒng)計(jì)學(xué)意義。 4、椎體上下終板的矢狀徑長度：同一椎間隙上終板下終板矢狀徑長度,差異無統(tǒng)計(jì)學(xué)意義。同一椎體下終板上終板矢狀徑長度,差異有統(tǒng)計(jì)學(xué)意義。 5、終板角度：椎體的上、下終板角度自C2至C7椎體分別依次遞減。除C2/3間隙外,C3/4、C4/5、C5/6、C6/7各間隙下終板上終板角度,差異有統(tǒng)計(jì)學(xué)意義。同一椎體的上終板下終板角度,差異有統(tǒng)計(jì)學(xué)意義。 6、終板曲率半徑：椎體的上、下終板曲率半徑自C2至C7分別依次遞增。同一椎間隙下終板上終板曲率半徑,差異有統(tǒng)計(jì)學(xué)意義。同一椎體的上終板下終板曲率半徑,差異有統(tǒng)計(jì)學(xué)意義。 7、上關(guān)節(jié)突角：自C2至C7以C5為中心呈U形分布,即C7C3C6C4C5,C7角度最大,其與C3、C4、C5、C6角度相互比較,差異有統(tǒng)計(jì)學(xué)意義。 結(jié)論：通過對頸椎側(cè)位X線片多項(xiàng)相關(guān)解剖學(xué)數(shù)據(jù)的測量,了解了不同節(jié)段解剖學(xué)參數(shù)的變化趨勢及差異,從而在一定程度上為頸人工椎間盤假體的設(shè)計(jì),包括假體的矢狀徑、高度、上下終板的形狀及弧度、假體形狀等方面提供理論參考數(shù)據(jù),使椎間盤假體能夠更好地恢復(fù)椎間隙高度,與椎體上下終板更好地匹配,更好地分散應(yīng)力,以減少或避免假體植入后的各種后期并發(fā)癥,提高頸人工椎間盤置換術(shù)的臨床療效。
[Abstract]:Objective: to study the variation trend and difference of cervical vertebrae parameters by measuring and analyzing the anatomical parameters of cervical lateral radiographs, and to provide theoretical data for the design of cervical artificial disc prosthesis. Methods: 40 cases of cervical vertebrae X-ray examination were selected from Qilu Hospital of Shandong University. The lateral cervical vertebrae radiographs were taken in the upright neutral position. The median sagittal diameter and height of the vertebral body, the anterior, central and posterior edge heights of the intervertebral space, the sagittal diameter length of the upper and lower endplates, the angle of the upper and lower endplates, the curvature radius of the upper and lower endplates of the vertebrae were measured in the imaging workstation platform, respectively. The angle of the upper articular process of the vertebral body. The measuring length is 0. 0lmm and the measuring angle is 0. 1. The measurement data are statistically analyzed. Results the median sagittal diameter of the vertebrae was: C7C6C3C4C5, C3C4C5 and C7, but there was no significant difference between the remaining vertebrae. 2. The central height of the vertebrae was: C7C3C4C5C6, C3C4C5C6 and C7, there was significant difference between C7C4C5C6 and C7C7C4C5C5. There was no statistical difference between the other vertebrae. 3. The height of the intervertebral space: the central height of the intervertebral space, the front height, the posterior edge height, the difference was statistically significant. There was no significant difference between C _ 2 / C _ 3 / C _ 3 / C _ 3 / C _ 4 / C _ 4 / C _ 4 / C _ 5 / 6 and C _ 6 / 7. 4. Sagittal diameter length of upper and lower endplate of vertebral body: the sagittal diameter length of inferior endplate of the same intervertebral space was not statistically significant. The sagittal diameter of superior endplate of the same vertebral body was significantly different. 5. Angle of endplate: the angle of upper and lower endplates of vertebral body decreased from C2 to C7 respectively. With the exception of C _ 2 / 3 gap, C _ 3 / 4 / C _ 4 / C _ 4 / C _ 5 / C _ 5 / C _ 5 / C _ 6 / 7, the difference is statistically significant. The angle of upper endplate and inferior endplate of the same vertebral body was significantly different. 6. Radius of curvature of endplate: the radius of curvature of upper and lower endplates of vertebral body increased from C2 to C7 respectively. The curvature radius of the superior endplate in the same intervertebral space was significantly different. The curvature radius of the upper and lower endplate of the same vertebral body was significantly different. 7. The angle of upper articular process: from C2 to C7 was U-shaped at the center of C5, that is, the angle of C7C3C6C4C5C5C7 was the largest, and the difference was statistically significant compared with that of C3C4C5C6. Conclusion: by measuring the relative anatomical data of lateral cervical X ray film, we can find out the change trend and difference of anatomical parameters in different segments, so as to design the prosthesis of cervical artificial intervertebral disc, including the sagittal diameter of the prosthesis, to a certain extent. The height, the shape and radians of the upper and lower endplates and the shape of the prosthesis provide theoretical reference data so that the intervertebral disc prosthesis can better restore the height of the intervertebral space, better match with the upper and lower endplates of the vertebral body, and distribute the stress better. In order to reduce or avoid all kinds of late complications after prosthesis implantation, improve the clinical effect of cervical artificial disc replacement.
