摘要

L5的解剖特征，包括其大小、形状和与骶骨的关节，使其成为重量转移和脊柱稳定的关键结构。了解其形态对诊断和治疗与腰椎相关的病理至关重要。本研究旨在提供关于第五腰椎（L5）的形态学和形态学尺寸的规范数据，并发现其临床意义，帮助临床医生（包括放射科医生和脊柱外科医生）制定术前计划。方法记录50块L5椎体的解剖测量，包括横突、关节面、椎体和椎间孔的尺寸。进行统计分析以评估形态计量学数据的相关性和差异。结果椎体：椎体上、下表面的平均正、横径分别为3.35±0.41 cm和4.74±1.39 cm（上）和3.33±0.68 cm和3.78±1.72 cm（下）。上、下表面的横径有显著差异。关节面：上关节面以四边形为主（46%），其次为锥体（30%）。下切面最常见为圆形（48%）。从棘突到下关节突的距离有显著差异。椎间孔：左右两侧椎间切迹的前后长度有显著差异。横突：左右横突尖端的平均距离为7.92±0.92 cm。从棘突到横突的距离呈弱正相关。结论该研究提供了第五腰椎的全面形态测量数据，强调了重要的解剖尺寸，对了解脊柱健康和指导临床干预至关重要。这些发现将有助于脊柱手术的术前计划和腰椎疾病的管理。建议采用更大、更多样化的样本进行进一步研究，以验证和扩展这些发现。

Morphometric analysis of the fifth lumbar vertebra (L5): Anatomical dimensions and clinical implications in South Indian population

Background

The anatomical features of L5, including its size, shape, and articulation with the sacrum, make it a crucial structure in weight transfer and spinal stability. Understanding its morphometry is vital for diagnosing and treating pathologies associated with the lumbar spine. This study aims to provide normative data on the morphological and morphometric dimensions of the fifth lumbar vertebra (L5) and discover its clinical implications, assisting in preoperative planning for clinicians, including radiologists and spine surgeons.

Methods

Anatomical measurements of fifty dry L5 vertebrae including dimensions of the transverse processes, articular facets, body of the vertebra, and intervertebral foramen, were recorded. Statistical analysis was performed to assess correlations and differences in morphometric data.

Results

Body of the vertebra: The mean anteroposterior and transverse diameters of the superior and inferior surfaces of the vertebral body were 3.35 ± 0.41 cm and 4.74 ± 1.39 cm (superior) and 3.33 ± 0.68 cm and 3.78 ± 1.72 cm (inferior), respectively. Significant differences were noted in the transverse diameter between the superior and inferior surfaces. Articular Facets: The superior articular facets were predominantly quadrilateral (46 %), followed by pyramidal (30 %). The inferior facets were most commonly circular (48 %). Significant differences were observed in the distance from the spinous process to the inferior articular facets. Intervertebral Foramen: The anteroposterior length of the intervertebral notch on the right and left sides was significantly variable. Transverse Processes: The mean distance between the tips of the right and left transverse processes was 7.92 ± 0.92 cm. Weak positive correlations were observed between the distance from the spinous process to the transverse processes.

Conclusion

The study provides comprehensive morphometric data on the fifth lumbar vertebra, emphasizing important anatomical dimensions that are vital for understanding spinal health and guiding clinical interventions. These findings will aid in the preoperative planning for spine surgeries and the management of lumbar spine disorders. Further research with larger and more diverse samples is recommended to validate and expand these findings.

期刊介绍： Translational Research in Anatomy is an international peer-reviewed and open access journal that publishes high-quality original papers. Focusing on translational research, the journal aims to disseminate the knowledge that is gained in the basic science of anatomy and to apply it to the diagnosis and treatment of human pathology in order to improve individual patient well-being. Topics published in Translational Research in Anatomy include anatomy in all of its aspects, especially those that have application to other scientific disciplines including the health sciences: • gross anatomy • neuroanatomy • histology • immunohistochemistry • comparative anatomy • embryology • molecular biology • microscopic anatomy • forensics • imaging/radiology • medical education Priority will be given to studies that clearly articulate their relevance to the broader aspects of anatomy and how they can impact patient care.Strengthening the ties between morphological research and medicine will foster collaboration between anatomists and physicians. Therefore, Translational Research in Anatomy will serve as a platform for communication and understanding between the disciplines of anatomy and medicine and will aid in the dissemination of anatomical research. The journal accepts the following article types: 1. Review articles 2. Original research papers 3. New state-of-the-art methods of research in the field of anatomy including imaging, dissection methods, medical devices and quantitation 4. Education papers (teaching technologies/methods in medical education in anatomy) 5. Commentaries 6. Letters to the Editor 7. Selected conference papers 8. Case Reports
