Abstract

Introduction: The aim of the present meta-analysis was to provide the most up-to-date and evidence-based results regarding the morphometric properties of the lumbar vertebrae.

Methods: Medical databases such as PubMed, Scopus, Embase, Web of Science, Google Scholar, and Cochrane Library were searched through.

Results: The results of this meta-analysis were established based on a total of 1481 patients. New results were established in 27 categories for each lumbar vertebra separately. The findings from this study reveal that the width of the spinal canal progressively increases towards the lower end of the lumbar spine (L1 = 22.04 mm, L5 = 26.46 mm). Additionally, the transverse processes exhibit a similar trend, widening as they approach the lower lumbar vertebrae (L1 = 68.08 mm, L5 = 85.91 mm). The pedicle height decreased from L1 to L4, with an increase observed at L5 (14.73 mm). No significant differences were observed between the measurements of the left and right pedicles.

Conclusion: The presented results provide physicians with normative morphometric data on the lumbar vertebrae. Having adequate knowledge of the anatomy of the lumbar vertebrae may be of immense use for surgeons performing various spinal surgeries, such as pedicle screw fixation, percutaneous endoscopic transforaminal discectomy, or lumbar disc replacement.

腰椎形态：对1481例脊柱手术患者进行meta分析的系统综述。

介绍：本荟萃分析的目的是提供有关腰椎形态计量学特性的最新和基于证据的结果。方法：检索PubMed、Scopus、Embase、Web of Science、谷歌Scholar、Cochrane Library等医学数据库。结果：本荟萃分析的结果是基于1481例患者建立的。对每个腰椎分别建立27个分类的新结果。本研究的结果显示，椎管宽度向腰椎下端逐渐增加（L1 = 22.04 mm, L5 = 26.46 mm）。此外，横突也表现出类似的趋势，在接近下腰椎时变宽（L1 = 68.08 mm, L5 = 85.91 mm）。从L1到L4，蒂高度逐渐降低，L5处增高（14.73 mm）。左右椎弓根的测量结果无显著差异。结论：本研究结果为临床医生提供了腰椎形态计量学的规范数据。拥有足够的腰椎解剖知识对于外科医生进行各种脊柱手术，如椎弓根螺钉固定、经皮内窥镜经椎间孔椎间盘切除术或腰椎间盘置换术，可能会有很大的帮助。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
