Abstract:
Background:: The brachial plexus is usually formed by the fusion of anterior primary rami
of the fifth to eighth cervical and the first thoracic spinal nerves. Variations in the formation
of the brachial plexus may occur. Variations in brachial plexus anatomy are important to
radiologists, surgeons and anaesthesiologists performing surgical procedures in the neck,
axilla and upper limb regions. These variations may lead to deviation from the expected dermatome
distribution as well as differences in the motor innervation of muscles of the upper
limb. This study is aimed to describe the anatomical variations of brachial plexus in its formation
among 20 Ethiopian cadavers.
