脊椎分解における神経弓と椎体の腰部形状特性：比較骨格研究

腰椎形状は、脊椎分解（SP）の重要な原因因子です。しかし、この形状の完全な特性評価は、その病態生理学に光を当てることで、以前の診断を促進しますが、まだ欠落しています。この研究の目的は、sp3次元（3D）デジタイザー、VBの長さ、幅、高さ、矢状のくさび、およびすべての腰椎椎骨（L1-L5）の長さ、薄骨脊椎、および横方向のプロセスを使用して、L5の二頭系SPを伴う115人の男性骨格、および120の正常なものを比較しました。正常群と比較して、以下の結果はSP [分散分析（ANOVA）、p <0.05]で示されました：VBはL1-L4の上面とL1-L3の下面で有意に長くなります（それぞれ総平均差= 7.61 mmおよび3.94 mm、それぞれ3.94 mm）、L1-L4の上面の上部ではwider式= 10.06および下面の優れた表面では、wider wider wider wider wider wider wider wider wider wider wider wider wider wider wider fide differenそれぞれ12.90 mm）;L5 VBは、後方（平均差= 3.05 mm）で大幅に短くなり、より長い（+1°の背部くさび）。L5は、より長い層（平均差= 1.85-2.18 mm）、より長い腸（平均差= 3.24-4.69 mm）、およびより長く幅の広い脊椎運河（それぞれ平均差= 3.64 mmおよび1.13 mm）で顕在化されています。L2-L5の棘プロセスは大幅に長い（合計平均差= 7.45 mm）。臨床的には、慢性腰痛に苦しむ個人で前述のユニークな腰椎形態計測特徴を検出すると、SPの早期診断が促進される可能性があります。

The lumbar vertebral shape is an important causative factor in spondylolysis (SP). However, a complete characterization of this shape, that would shed light on its pathophysiology enhance its earlier diagnosis, is still missing. The aim of this study was to evaluate the shape distinctiveness of the lumbar (L1-L5) vertebral body (VB) and neural arch (isthmus, lamina, vertebral canal, spinous, and transverse processes) in SP. Using a three-dimensional (3D) digitizer, the VB length, width, height, and sagittal wedging as well as the lengths of the isthmus, lamina spinous, and transverse processes of all lumbar vertebrae (L1-L5) were measured from 115 male skeletons with bilateral SP at L5 and compared with 120 normal ones. Compared with the normal group, the following results were indicated in SP [analysis of variance (ANOVA), P < 0.05]: the VB's are significantly longer at the superior surfaces of L1-L4 and inferior surfaces of L1-L3 (total mean difference = 7.61 mm and 3.94 mm, respectively), and wider at the superior surfaces of L1-L4 and inferior surfaces of L1-L5 (total mean difference = 10.06 mm and 12.90 mm, respectively); The L5 VB is significantly shorter posteriorly (mean difference = 3.05 mm) and more lordotic (+1° of dorsal wedging); L5 is manifested with longer lamina (mean difference = 1.85-2.18 mm), longer isthmus (mean difference = 3.24-4.69 mm), and longer and wider vertebral canal (mean differences = 3.64 mm and 1.13 mm, respectively); The L2-L5 spinous processes are significantly longer (total mean difference = 7.45 mm). Clinically, detecting the aforementioned unique lumbar vertebral morphometric features in individuals suffering from chronic low back pain may facilitate the early diagnosis of SP.
