To measure the morphological dimensions of the spinous process (SP) and interspinous space, and provide a basis for the development of interspinous devices for the Korean or East Asian populations.
We retrospectively analyzed the anatomical parameters of 120 patients. The parameters included height, length, and width of SP, interspinous distance (supine, standing, and dynamic), cortical thickness of SP, and spino-laminar (S-L) angle. Correlations between measurements, age, and gender were investigated.
The largest height, length, and cortical thickness and S-L angle were noted at L3. The largest width was observed at S1. The interspinous distance decreased significantly from L2-3 to L5-S1 and was significantly larger in the supine than in standing posture for L5-S1. Cortical thickness was gradually tapered from the anterior to the posterior position. The S-L angle at L2 and L3 was similar and significantly decreased from L3 to S1. An increased trend in width with aging and a decreased trend in distance (supine) were noted. A significant increase in height, length, and distance in males compared with females was also observed.
The interspinous space is wider at the anterior, and the cortex is thicker anteriorly. Accordingly, it appears that the optimized implant position lies in the interspinous space anteriorly. The varying interspinous space with different postures and gradually narrowing with age suggest the need for caution when sizing the device. Gender differences also need to be considered when designing implantable devices.
测量棘突（SP）和棘突间间隙的形态学尺寸，为韩国或东亚人群棘突间装置的研发提供依据。
我们回顾性分析了120例患者的解剖学参数。这些参数包括棘突的高度、长度和宽度、棘突间距离（仰卧位、站立位和动态）、棘突皮质厚度以及棘突-椎板（S-L）角。研究了各项测量值与年龄和性别的相关性。
L3的高度、长度、皮质厚度和S-L角最大。S1的宽度最大。棘突间距离从L2-3至L5-S1显著减小，且L5-S1在仰卧位时的棘突间距离明显大于站立位。皮质厚度从前向后逐渐变窄。L2和L3的S-L角相似，从L3至S1显著减小。观察到宽度随年龄增长有增加趋势，仰卧位时距离有减小趋势。与女性相比，男性的高度、长度和距离也显著增加。
棘突间间隙在前部较宽，皮质在前部较厚。因此，似乎优化的植入位置位于前部的棘突间间隙。不同姿势下棘突间间隙不同且随年龄逐渐变窄，这表明在确定装置尺寸时需要谨慎。在设计可植入装置时也需要考虑性别差异。
