Abstract

During routine dissection of the anterior compartment of the arm region, we encountered several variations in the muscular and neural structures in the right upper extremity of a female cadaver. We observed one superiorly positioned extramuscular head with fibers originating from both the biceps brachii (BB) and coracobrachialis (CB) muscles and one inferiorly positioned extramuscular head with fibers solely from the BB muscle. The musculocutaneous nerve did not penetrate the CB muscle, but instead provided a muscular branch that communicated with the median nerve (MN). Both the MN and brachial artery (BA) flow beneath the extra head. This case suggests that the described variations may contribute to the entrapment of the MN and compression of the BA. Understanding these variations is crucial before surgical intervention. The failure to recognize such anatomical nuances could lead to inadvertent nerve injury or compromised vascular perfusion, emphasizing the need for preoperative planning and intraoperative vigilance.

重新审视手臂前室的肌肉和神经:病例报告。
在对手臂前部区域进行常规解剖时,我们发现一具女性尸体右上肢的肌肉和神经结构存在多种变化。我们观察到一个位置偏上的肌外头,其纤维同时来源于肱二头肌(BB)和肱角肌(CB);一个位置偏下的肌外头,其纤维仅来源于肱二头肌(BB)。肌皮神经没有穿透 CB 肌肉,而是提供了一条与正中神经(MN)相通的肌肉分支。正中神经(MN)和肱动脉(BA)都流经额外头部的下方。该病例表明,上述变异可能会导致正中神经卡压和肱动脉受压。在手术干预之前,了解这些变异至关重要。如果认识不到这些解剖学上的细微差别,可能会导致意外的神经损伤或血管灌注受损,这就强调了术前规划和术中警惕的必要性。

Medeniyet Medical Journal is the continuation of Göztepe Medical Journal (ISSN: 1300-526X) which was started publishing in 1985. It changed the name as Medeniyet Medical Journal in 2015. Submission and publication are free of charge. No fees are asked from the authors for evaluation or publication process. All published articles are available online in the journal website (www.medeniyetmedicaljournal.org) without any fee. The journal publishes intradisciplinary or interdisciplinary clinical, experimental, and basic researches as well as original case reports, reviews, invited reviews, or letters to the editor, Being published since 1985, the Medeniyet Med J recognizes that the best science should lead to better lives based on the fact that the medicine should serve to the needs of society, and knowledge should transform society. The journal aims to address current issues at both national and international levels, start debates, and exert an influence on decision-makers all over the world by integrating science in everyday life. Medeniyet Med J is committed to serve the public and influence people’s lives in a positive way by making science widely accessible.
