摘要:

       目的  测量青少年(14~19岁)脊柱胸腰段椎板峡部上下缘的厚度、峡部上下缘距离及椎板厚度值,为临床及运动医学应用提供解剖学基础。 方法  年龄在14~19岁(平均16.5岁)25例原配完整的胸腰段(T1~L5)标本,分别测量峡部上缘厚度,峡部下缘厚度,峡部上下缘距离和椎板厚度并对峡部上下缘厚度进行比较、分析。 结果  峡部上缘厚度:胸段在(2.96±0.69) mm~(3.74±0.55)mm之间,呈逐渐上升趋势,腰段在(4.29±0.98 )mm~(4.83±0.80) mm之间呈逐渐下降的趋势。峡部下缘厚度:胸段由(4.52± 1.06) mm到(5.11±0.99)mm呈逐渐上升的趋势;腰段在(6.06±1.03) mm到(7.30±1.24) mm之间,变化不大。峡部上、下缘为近似“双轨”的曲线,上、下缘间差值保持在2.00mm左右。峡部上下径:整体在(17.51±3.55)mm ~(7.90±1.71)mm之间,胸段呈上升的趋势,腰段呈下降的趋势。椎板厚度:整体在(4.94± 1.00)mm~(6.79±1.01)mm之间,呈两端高中间低的“马鞍形”。 结论  青少年胸腰椎峡部与椎板相关参数变化有一定规律,峡部下缘总是较上缘厚,且具有一定的差值;其与成人数据相比较,无显著性差异。

Abstract:

        Objective  To provide anatomic basis for clinical application and athletic medicine, by analyzing the thickness of superior and inferior border of interarticularis(STI and ITI ), the distance between superior and inferior border of interarticularis(DSII) and the thickness of vertebral laminae(TVL) on adolescent thoracic and lumbar spine.  Methods  25 specimens(T1~L5)from adolescents(aged from 14 to 19 years, averagely 16.5 year) were measured and compared, with the anatomic parameters of STI, ITI, DSII and TVL. Results  STI increased gradually, from T1 to T12 level(ranged from 2.96±0.69 mm to 3.74±0.55 mm), and then decreased from L1 to L5 level (ranged from 4.29±0.98mm to 4.83±0.80mm); ITI increased from T1 to L5 level(ranged from 4.52±1.00mm to 7.30±1.24mm); DSII increased from T1 to T12 level and decreased from L1 to L5 level(ranged between 17.51±3.55mm and 7.90±1.71mm); TVL ranged between (17.51±3.55)mm and (7.90±1.71)mm, and presented the shape of sella.  Conclusions  The results of thoracic and lumbar vertebral laminae and interarticularis in adolescents show that, ITI is always thicker than STI.
