The brachial plexus is a part of the peripheral nervous system, responsible for innervation of the shoulder, upper extremity upper chest muscles, and cutaneous nerves of the skin and hand. The brachial plexus can be involved in many different pathological processes which can broadly be classified into two categories: traumatic and non-traumatic. The therapeutic measures for brachial plexus injury depend on the pathologic condition and the location of the injury. Damage to the brachial plexus i.e. cervical spine and nerves may result in profound functional disability in the arm and shoulder. Diagnosing brachial plexus pathologies can be clinically challenging due to its complex anatomy and non-specific symptomatology. Clinical examination and electrophysiological studies may be useful but may not provide accurate diagnosis or localization. Hence imaging plays a very important role in the evaluation of brachial plexus pathologies. MRI plays an essential role in differentiating preganglionic injuries from postganglionic lesions, a differentiation that is crucial for determining the management of brachial plexus injury. Our study aims to determine the efficacy of MRI in Brachial plexopathy in correlation with patients who underwent Nerve conduction study at our institution.
