Abstract

Purpose: The current meta-analysis aimed to investigate the extensor digitorum brevis manus (EDBM) muscle variability by calculating the pooled prevalence of all published variants. After considering the pooled prevalence, these variants were classified based on their insertion and relationship with the extensor indicis (EI) muscle and/or tendon. The origin of the variants, neural and arterial supply, and the terminology of the EDBM variants were further investigated.

Materials: The systematic review was conducted according to the guidelines proposed by the Evidence-Based Anatomy Workgroup and PRISMA 2020. Four databases were searched using several keyword combinations. The included studies were statistically meta-analyzed using the R programming language. The EDBM pooled prevalence was calculated, as were subgroup analyses of a few parameters.

Results: Thirty-one studies met our inclusion criteria, with a total sample of 9686 hands. The EDBM pooled prevalence was estimated at 1.96% (95%CI 1.42-2.58). The EDBM's most common insertion was via a distinct tendon to the index finger, coexisting with the typical EI tendon (0.38% pooled prevalence). The origin, innervation, and arterial supply of EDBM have not been studied systematically.

Conclusions: The EDBM variant can be considered infrequent, with a pooled prevalence of 1.96%. Particular attention should be given to the muscle's insertion and relationship with the EI muscle and tendon. Knowledge of the EDBM morphological variability is adequate for hand and reconstructive surgeons to avoid confusion intraoperatively and misdiagnosis preoperatively.

指短伸肌变异性及临床意义：一项系统综述及荟萃分析。

目的：当前的荟萃分析旨在通过计算所有已发表的变异的总流行率来研究指短手伸肌（EDBM）肌肉的变异性。在综合考虑患病率后，这些变异根据其插入和与指伸肌和/或肌腱的关系进行分类。变异的起源，神经和动脉供应，以及EDBM变异的术语进一步研究。材料：系统评价按照循证解剖学工作组和PRISMA 2020提出的指南进行。使用几个关键字组合搜索了四个数据库。纳入的研究使用R编程语言进行统计荟萃分析。计算EDBM总患病率，并对几个参数进行亚组分析。结果：31项研究符合我们的纳入标准，共纳入9686只手。EDBM总患病率估计为1.96% （95%CI 1.42-2.58）。EDBM最常见的插入是通过一个独特的肌腱到食指，与典型的EI肌腱共存（总患病率为0.38%）。EDBM的起源、神经支配和动脉供应尚未有系统的研究。结论：EDBM变异可以认为是罕见的，总患病率为1.96%。应特别注意肌肉的插入以及与EI肌和肌腱的关系。了解EDBM形态学的变异对手部和重建外科医生来说是足够的，以避免术中混淆和术前误诊。

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.
