“…The Radial nerve can show variations in its origin, branching and communications. Abnormal communications of the Radial nerve with the ulnar nerve have been reported in the plexus where the communicating branch was a separate filament given off from the radial nerve before entering the spiral groove where it did not mingle with the Ulnar nerve fibres but entered the sheath and finally ended supplying the Triceps muscle [8]. In our study, the accessory branch that had schwannoma in it was supplying the triceps muscle.…”

“…In the available literature there are few reports concerning such connections of the radial nerve [ 6 ]. Konstantinos Natsis et al [ 16 ] in 2018 published three studies in which they confirmed that connections between the radial and ulnar nerves may occur relatively more frequent than it was reported in previous studies. This represented 2.6% of the total 266 detected upper limbs from 133 cadavers [ 16 ].…”

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

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.

“…Natsis et al examined 133 Greek cadavers and found that a RN-UN communication occurred in 3 cases (2.3%). 2 Especially, in 2 cadavers the communication was held unilateral, in the left side (1.5%) and in one cadaver the variation occurred bilateral (0.7%). Additional 16 studies revealed connections between these two nerves.…”

The ulnar nerve originates from the anterior division of the lower trunk of the brachial plexus which continues as the medial cord and gives off branches to the forearm and the hand with motor and sensory fibers. The objective of the current study is to assemble the recognized anatomical variations of the ulnar nerve (UN) and underline their clinical impact. A literature search was undertaken via PubMed database, using the term: "ulnar nerve AND variations." Classical anatomical textbooks were also used for the normal anatomy of the UN. A total of 23 articles met the inclusion criteria, 16 of which are included in this review. Fifty-four additional articles provided useful information according to the aim of this review. Of great interest is the communication between the UN and the radial nerve (RN) in the forearm, as well as the communication between the UN and the median nerve (MN) in both forearm and hand. Furthermore, variations of the UN were observed in the hand and the classification of the UN compression was also described according to the point of the neuropathy. These collecting data are categorized into five tables. Additional aberrations were also included in this review. According to literature, the UN is characterized by numerous variations of its course and branches. Therefore, good knowledge of the normal anatomy is essential. Moreover, the anomalies are of particular importance due to their significant clinical implications and should be taken into consideration by the surgeons during surgical procedures in this region.
