Abstract

Background/objectives: A thorough understanding of spinal anatomy is essential for diagnostic assessment and surgical intervention. Interspinous distance (ISD), neuroforaminal dimensions (NFDs), and disc space height (DSH) have each been studied separately; however, their interrelationship remains unstudied. Given the use of interspinous implants as a minimally invasive treatment for lumbar stenosis and degenerative disc disease, defining these relationships is of growing clinical significance. This study investigates the correlation between ISD and both NFDs and DSH in a normative population and whether ISD varies with demographic factors.

Methods: A retrospective chart review was performed on 852 patients who underwent CT imaging of the lumbar spine. ISD was measured from L1 to L5 as the shortest distance between the most caudal tip of the superior spinous process and the inferior spinous process. DSH was measured at the anterior, middle, and posterior margins. NFDs were assessed in axial and sagittal views, including axial width, craniocaudal height, and foraminal area. Statistical analysis assessed correlations between ISD, NFDs, DSH, and demographic variables.

Results: No strong correlation was observed between ISD and either NFDs or DSH. Slightly greater correlation was present at L1-L3, weakening at L4-L5, where interspinous implants are most commonly placed. Demographic analysis revealed no consistent relationship between ISD and ethnicity, sex, or BMI. While it may be expected that larger ISD correlates with greater NFDs or DSH, our findings do not support this assumption.

Conclusions: ISD does not strongly correlate with NFDs or DSH, and demographic factors do not significantly influence ISD in a healthy population.

腰椎棘突间距离与椎间孔尺寸、椎间盘间隙高度和患者人口统计学因素的相关性。

背景/目的：深入了解脊柱解剖对诊断评估和手术干预至关重要。棘间距离（ISD）、神经间孔尺寸（NFDs）和椎间盘间隙高度（DSH）分别进行了研究；然而，它们之间的相互关系尚未得到研究。鉴于棘突间植入物作为腰椎管狭窄和退变性椎间盘疾病的微创治疗，确定这些关系具有越来越重要的临床意义。本研究探讨了正常人群中ISD与NFDs和DSH的相关性，以及ISD是否随人口统计学因素而变化。方法：回顾性分析852例腰椎CT显像患者的资料。ISD从L1到L5测量，这是上棘突最尾端与下棘突之间的最短距离。测量前、中、后缘的DSH。通过轴向和矢状面评估NFDs，包括轴向宽度、颅趾高度和椎间孔面积。统计分析评估了ISD、NFDs、DSH和人口统计学变量之间的相关性。结果：ISD与NFDs、DSH均无明显相关性。L1-L3的相关性略高，L4-L5的相关性减弱，而L4-L5是棘间植入物最常放置的地方。人口统计学分析显示，ISD与种族、性别或体重指数之间没有一致的关系。虽然可以预期较大的ISD与较大的NFDs或DSH相关，但我们的研究结果并不支持这一假设。结论：ISD与NFDs或DSH没有强相关性，人口因素对健康人群的ISD没有显著影响。

期刊介绍： TomographyTM publishes basic (technical and pre-clinical) and clinical scientific articles which involve the advancement of imaging technologies. Tomography encompasses studies that use single or multiple imaging modalities including for example CT, US, PET, SPECT, MR and hyperpolarization technologies, as well as optical modalities (i.e. bioluminescence, photoacoustic, endomicroscopy, fiber optic imaging and optical computed tomography) in basic sciences, engineering, preclinical and clinical medicine. Tomography also welcomes studies involving exploration and refinement of contrast mechanisms and image-derived metrics within and across modalities toward the development of novel imaging probes for image-based feedback and intervention. The use of imaging in biology and medicine provides unparalleled opportunities to noninvasively interrogate tissues to obtain real-time dynamic and quantitative information required for diagnosis and response to interventions and to follow evolving pathological conditions. As multi-modal studies and the complexities of imaging technologies themselves are ever increasing to provide advanced information to scientists and clinicians. Tomography provides a unique publication venue allowing investigators the opportunity to more precisely communicate integrated findings related to the diverse and heterogeneous features associated with underlying anatomical, physiological, functional, metabolic and molecular genetic activities of normal and diseased tissue. Thus Tomography publishes peer-reviewed articles which involve the broad use of imaging of any tissue and disease type including both preclinical and clinical investigations. In addition, hardware/software along with chemical and molecular probe advances are welcome as they are deemed to significantly contribute towards the long-term goal of improving the overall impact of imaging on scientific and clinical discovery.
