Abstract

Background: Lumbar ribs (LR) are a rare and relatively unknown anatomical abnormality of the lumbar spine. The literature provides better understanding regarding other spinal congenital variations like cervical ribs or lumbosacral transitional vertebrae, which are rather commonly recognised conditions. Thus, this meta-analysis aimed to provide data on prevalence and key characteristics of LR.

Methods: Relevant databases were systematically searched for studies reporting the prevalence, laterality and geographic distribution of LR. No exclusion criteria based on language and date of original articles were employed. The pooled prevalence estimates (PPE) were calculated using a random-effects model. To assess the between-study heterogeneity, the I² statistic and Chi-square test were utilized. Throughout the investigation, the PRISMA guidelines were adhered to scrupulously. Evaluation of the included studies' reliability was made with the AQUA tool.

Results: In total, 9 studies were included in this meta-analysis. The pooled prevalence estimate (PPE) of LR was 2.1% (95%CI: 1.0-4.6). In studies based on CT imaging, LR were found in 1.6% (95%CI: 0.6-4.3) of patients and in Xray based studies in 2.1% (95%CI: 0.4-11.1) of patients. Lumbar ribs were bilateral in majority of individuals (65.4%, 95%CI: 39.4-84.6) and could be most frequently encountered in Europe with PPE of 2.8% (95%CI: 3.0-20.0), then in East Asia with PPE of 1.5% (95%CI: 1.0-19.2) and Middle East with PPE of 1.1% (95%CI: 0.6-20.0).

Conclusions: The findings of our study indicate that LR are a common anatomical variation of lumbar spine, contrary to previous beliefs. In a clinical practice, when a patient presents with a non-specific low back pain, a possible occurrence of LR should be taken into consideration. The presence of LR may be misleading for surgeons and result in wrong-level spine surgeries.

腰肋骨的发病率和特征：一项包含解剖学和临床考虑因素的荟萃分析。

背景：腰肋是一种罕见且相对未知的腰椎解剖异常。文献提供了对其他脊柱先天性变异（如颈椎肋骨或腰骶过渡椎）的更多了解，这些都是比较常见的情况。因此，本荟萃分析旨在提供有关 LR 发病率和主要特征的数据：对相关数据库进行了系统性检索，以查找报告 LR 发病率、侧位和地理分布的研究。没有采用基于语言和原始文章日期的排除标准。采用随机效应模型计算了汇总的患病率估计值（PPE）。为了评估研究间的异质性，采用了 I2 统计量和卡方检验。整个调查过程严格遵守了 PRISMA 指南。使用 AQUA 工具对纳入研究的可靠性进行了评估：本次荟萃分析共纳入了 9 项研究。LR的汇总患病率估计值（PPE）为2.1%（95%CI：1.0-4.6）。在基于 CT 成像的研究中，1.6%（95%CI：0.6-4.3）的患者发现了 LR，而在基于 X 射线的研究中，2.1%（95%CI：0.4-11.1）的患者发现了 LR。大多数患者的腰肋骨为双侧（65.4%，95%CI：39.4-84.6），在欧洲最常见，PPE 为 2.8%（95%CI：3.0-20.0），然后是东亚，PPE 为 1.5%（95%CI：1.0-19.2），中东，PPE 为 1.1%（95%CI：0.6-20.0）：我们的研究结果表明，LR 是一种常见的腰椎解剖变异，这与之前的观点相反。在临床实践中，当患者出现非特异性腰背痛时，应考虑到可能存在 LR。LR的存在可能会误导外科医生，导致错误的脊柱手术。

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.
