[Brachial Plexus: Dissection At The Laboratory Of Anatomy Of Bamako]
Introduction:
The brachial plexus consists of the ventral twigs of the last four cervical nerves and the first thoracic nerve. It ensures the motor and sensitive innervations of the thoracic limb.
Aim:
Our goal was to describe the brachial plexus of the cervical region to the middle third of the arm.
Methodology:
We conducted a prospective study at the anatomy Laboratory of the Faculty of Medicine and Dentistry in Bamako from September 2016 to October 2017. We dissected the brachial plexus (PB) of 13 fresh adult corpses on both sides. The inclusion criteria were: Fresh adult corpses with cervical regions and brachial without scarring. The injected or scar-carrying corpses were not included in the cervical and brachial regions.
Results:
Twenty-six brachial plexus of which 18 bp in men and 8 bp in women were dissected. The average age of the subjects was 42 years (extreme: 18 and 70 years). We noted nerve block variations in 3.8%, fascicular in 3.8% and late terminal in 73.1%. The involvement of the anterior branch of the fourth spinal nerve (C4) was found in 46.2%.
Conclusion:
The brachial plexus is the seat of many anatomical variations whose knowledge is indispensable to treat its lesions.
