“…2 The DTBB has several anatomical variants on its distal attachment. 3 Athwal et al described two different components of DTBB. The first one, made by the long head of the biceps brachii (BB), attaches to the superior aspect of the radial tuberosity.…”

A revisão bibliográfica do presente estudo demonstrou que o Bíceps Braquial é composto de uma arquitetura complexa e variável na sua composição. Através da análise de artigos dos últimos cinco anos, concluímos que tal grupo muscular, que cobre quase a totalidade da face anterior do braço e que realiza movimentos nas articulações do ombro, cotovelo e radio ulnar, não conta somente com dois músculos em 100% dos braços humanos, como cita a literatura clássica. Pode ter variantes anatômicas nos seus ventres musculares que agreguem até cinco estruturas na sua composição, com uma possibilidade de 17,18% (variando de 9,73 a 36%) de existirem essas variações extranumerárias aos dois ventres musculares no denominado “bíceps”.

An unreported innervation of the coracobrachialis longus by the radial nerve: a potential pitfall for clinicians

et al. 2023

Purpose The aim of the presented case is to describe an unprecedented innervation of the coracobrachialis longus muscle by the radial nerve. Methods An 82-year-old body donor at death was subjected to a routine anatomical dissection for teaching and research purposes at the Department of Anatomical Dissection and Donation in Lodz, Poland. Results We have found an additional branch of the radial nerve, which departed from it just below its beginning. Its initial section ran alongside the radial nerve in the axilla, then headed medially accompanying superior ulnar collateral artery. Then, it reaches the coracobrachialis longus muscle and is the only one to innervate it. Conclusions The brachial plexus (BP) is very variable and well understood. Nevertheless, we must remember that there may still be variations in its structure, which may involve problems at every stage of diagnosis and treatment of diseases associated with its structures. Their knowledge is extremely important.
