Study Notes
Causes of Brachial Plexus Injuries
- Motor vehicle accidents, falls from a height, sports injuries, and direct blows to the shoulder or neck can cause brachial plexus injuries due to trauma
- Birth injuries, such as obstetric brachial plexus palsy, can occur due to difficulty delivering the baby's shoulder or head, or use of forceps or vacuum extraction during delivery.
- Growing tumors or metastatic tumors that spread to the brachial plexus can cause compression and lead to injuries
- Abscesses or infections that compress the brachial plexus can cause injuries
- Radiation therapy can damage the brachial plexus, leading to injuries
Symptoms of Brachial Plexus Injuries
- Weakness or paralysis of the arm or hand can be a symptom of brachial plexus injuries
- Numbness or tingling in the arm or hand can indicate a brachial plexus injury
- Loss of sensation or feeling in the arm or hand can be a symptom of brachial plexus injuries
- Pain in the neck, shoulder, or arm can occur due to brachial plexus injuries
- Decreased reflexes can be a symptom of brachial plexus injuries
- Abnormal sensations, such as burning or coldness, can occur in the arm or hand
- Difficulty controlling the arm or hand can be a symptom of brachial plexus injuries
- Drooping or sagging of the arm or hand can be a visible symptom of brachial plexus injuries
Diagnosis of Brachial Plexus Injuries
- Physical examination is used to assess muscle strength, sensation, and reflexes
- Imaging studies, such as X-rays, MRI, or CT scans, are used to visualize the brachial plexus and rule out other conditions
- Electromyography (EMG) measures electrical activity in muscles to aid in diagnosis
- Nerve conduction studies (NCS) measure electrical impulses in nerves to aid in diagnosis
Treatment of Brachial Plexus Injuries
- Non-surgical treatment includes physical therapy to improve range of motion and strength, pain management, and occupational therapy
- Surgical treatment may involve nerve repair or reconstruction, nerve grafting, tumor removal, or reconstructive surgery
- Rehabilitation involves aggressive physical therapy to improve function and strength, and regular follow-up with healthcare providers to monitor progress
