Middle brachial plexus neuropathy, also known as middle trunk or neuropraxic brachial plexus injury, is a condition characterized by damage or dysfunction to the nerves of the middle section of the brachial plexus. The brachial plexus is a network of nerves that originates from the spinal cord in the neck and supplies the upper extremities with motor and sensory functions.
In the case of middle brachial plexus neuropathy, the injury typically occurs at the level of the C8-T1 nerve roots or the middle trunk of the brachial plexus. This may result from various causes, including trauma, sports injuries, repetitive motions, or compression of the nerves. Symptoms may include pain, weakness, numbness, tingling, and limited range of motion in the affected arm, shoulder, or hand.
The diagnosis of middle brachial plexus neuropathy is usually made through a combination of physical examination, medical history, and imaging studies. Treatment options depend on the underlying cause and severity of the neuropathy. Conservative approaches may include rest, physical therapy, and pain management techniques. In more severe cases, surgical intervention might be necessary to repair or release any compressed or entrapped nerves.
Prognosis for recovery from middle brachial plexus neuropathy varies depending on the extent and nature of the injury. While some cases may fully resolve with appropriate treatment and rehabilitation, others may result in long-term or permanent disability. Early diagnosis and prompt intervention significantly improve the chances of successful recovery. Individuals affected by middle brachial plexus neuropathy may benefit from collaborating with healthcare professionals, such as neurologists, physiotherapists, and occupational therapists, to optimize their management and maximize functional outcomes
