Objective To provide an anatomic data of the lumbar isthmus, and to increase the fusion rate of the graft bone for spondylolisthesis treated with posterolateral spinal fusion and Steffee plate fixation. Methods The area and volume of the bone graft bed for posterolateral spinal fusion in the lumbar isthmus were studied on 30 dried specimens of adult lumbar spines from L 1 to L 5(a total of 150 lumbar vertebrae) with a vernier calipers, a goniometer and a graduate.

Objective To provide an anatomic data of the lumbar isthmus, and to increase the fusion rate of the graft bone for spondylolisthesis treated with posterolateral spinal fusion and Steffee plate fixation. Methods The area and volume of the bone graft bed for posterolateral spinal fusion in the lumbar isthmus were studied on 30 dried specimens of adult lumbar spines from L 1 to L 5(a total of 150 lumbar vertebrae) with a vernier calipers, a goniometer and a graduate. Results The length of the superior edge of the isthmus gradually increased from L 1[(7.34± 1.15) mm] to L 5[(10.31± 1.89) mm], and that of its inferior edge progressively decreased from L 1[(6.63± 1.24) mm] to L 5 [( 4.73± 1.21) mm]. The superior edge of the isthmus was the thinnest at L 1[(1.85± 0.64)mm], and the thickness increased inferiorly from L 1[(6.57± 1.24) mm] to L 5[(7.57± 1.16) mm]. The medial and caudal inclination of the isthmus with respect to the pedicle gradually increased from L 1 (113.9°± 13.3° ) to L 5(119.1°± 13.5° ) medial inclination and from (101.2°± 9.5° ) at L 1 to (117.6°± 13.4° ) at L 5 caudal inclination, respectively. The length of the superior edge of the isthmus and the transverse diameter of the pedicle were positively correlated to the vertebral levels. The length of the inferior edge of the isthmus were negatively correlated to the vertebral levels. The dimensions of the graft bed area were postively correlated to dimensions of the graft bone volume. Conclusion The application of firm spinal internal fixation system with adequate graft bed area and adequate graft volume, the maintenance of close contact between the graft bed and the graft bone, and adequate period of postoperative stable contact of the graft in bed were the keys to enable reduction of the spondylolisthesis and to increase the fusion rate of posterolateral bone graft.

To provide anatomical basis for the application of modified Stefee plate in internal fixation of lumbosacral vertebrae. Methods: The Steffee operations of L5 spondylolisthesis were simulated in 8 adult cadavers. Steffee plate and modified Steffee plate were fixed respectively in L4- S1 vertebrac, and the difference of the two types of internal fixation apparatus were compared. Furthermore, datum about the internal fixation of vertebral pedicle was measured on 15 dry lumbosacral vertebra specimens. Results:...

To provide anatomical basis for the application of modified Stefee plate in internal fixation of lumbosacral vertebrae. Methods: The Steffee operations of L5 spondylolisthesis were simulated in 8 adult cadavers. Steffee plate and modified Steffee plate were fixed respectively in L4- S1 vertebrac, and the difference of the two types of internal fixation apparatus were compared. Furthermore, datum about the internal fixation of vertebral pedicle was measured on 15 dry lumbosacral vertebra specimens. Results: While fixing S1 vertebral pedicle with traditional Steffee plate, screws were difficult to be fixed,and slipped into the spinal canal easily,or the upper 2 screws can be easily inserted into the hole of the plate, but the lower screws were difficult to be inserted into. Conclusion: Having scientific morphological basis, modified Steffee plate can be applied to clincal operation.

目的:为改良Steffee钢板在腰骶椎内固定术中的应用提供解剖学基础。方法:在8具成人尸体标本上摹拟L5脊椎滑脱的Steffee手术治疗。在L4~S1脊椎上分别安放Steffee钢板和改良Steffee钢板,比较2种内固定器械固定位置的解剖差异,并对15副腰骶椎干燥骨标本做了经椎弓根内固定相关的数据测量。结果:传统的Steffee钢板固定S1椎弓根螺钉安放困难,且进入椎管的机会多,或者是上2枚螺钉易套入钢板槽孔,而下面的螺钉难以套入钢板槽孔。改良Steffee钢板可克服上述弊端,更符合局部解剖形态要求。结论:改良Steffee钢板有科学的形态学依据,可临床试用。

Methods: The disc height ratio , facet joint orientation and transverse articular dimensions of Forty-two patie nts with lumbar degenerative spondylolisthesis (LDS) and fifty-two with lumbar d iscs herniated (LDH) were measured by X-ray and computed tomographic scans. Res ults: The zygapophysial joints of LDS group were more trend to the sagital posit ion, and the decrease in disc height...

Objective: To investigate the roles of the changed facet joint shapes in lumbar degenerative spondylolisthesis. Methods: The disc height ratio , facet joint orientation and transverse articular dimensions of Forty-two patie nts with lumbar degenerative spondylolisthesis (LDS) and fifty-two with lumbar d iscs herniated (LDH) were measured by X-ray and computed tomographic scans. Res ults: The zygapophysial joints of LDS group were more trend to the sagital posit ion, and the decrease in disc height ratio and facet joint transverse dimension were found in the Group LDS comparing with Group LDH.Conclusions: The shape of facet joint plays an important role in the patho-anatomic mechanism of LDS.

目的:研究腰椎关节突关节形态变化及其对腰椎退行性变滑脱的影响。方法:随机抽取42例腰椎退行性变滑脱(LDS)、52例腰椎间盘突出症(LDH)的病人的X光、CT进行测量其椎间盘的高度比、关节突关节的角度以及关节突关节的横径数据进行统计处理与分析。结果:与LDH组相比,LDS组的关节突关节角偏矢状角,其椎间盘的高度比以及关节突关节的横径均较少。结论:腰椎关节突关节宽基部横径越小,该关节角度越趋于矢状位,腰椎滑移几率越高。
