Board-certified plastic and reconstructive surgeon Dr. Jason Ko is a world-renowned brachial plexus and peripheral nerve reconstruction specialist based in Chicago, IL. This highly complex group of injuries requires specialized care and the high-level expertise that only a master surgeon can provide.
Brachial Plexus Anatomy and Function
The brachial plexus is a nerve network starting in the spinal cord in the neck, extending through the shoulder and down the arm. It controls muscle movements and sensations in the shoulders, arms, and hands.
This complex structure includes five main nerves that each play a distinct role in enabling movement and sensory feedback in the upper limbs. Any trauma to this nerve network can impact daily function and quality of life.
How Brachial Plexus Trauma Affects the Nervous System
Nervous system trauma disrupts signals between the brain and muscles, leading to weakness, numbness, and, in severe cases, complete paralysis of the affected limb. Time is of the essence when treating these problems (ideally within six months of the injury). The earlier you seek intervention, the better the chances are that you will recover function in the affected areas.
Causes of Brachial Plexus Trauma
Brachial plexus trauma may occur due to auto accidents, motorcycle injuries, sports injuries, birth injuries, surgery affecting nerves, or other sources of
injury like gunshots or stab wounds. Some of the specific injuries that may occur are:
- Neuropraxia: When brachial plexus nerves are stretched to the point of injury.
- Nerve Rupture: When a nerve tears either partially or all the way through.
- Avulsion: Brachial plexus avulsion happens when nerve roots pull free of the spinal cord.
- Neuroma: After surgery, a healing nerve may develop tough scar tissue, causing a growth that pressures a brachial plexus nerve.
- Shoulder Dystocia: When a baby’s shoulder gets stuck during vaginal delivery, it can cause brachial plexus damage.
These are some of the most common examples of brachial plexus trauma, but other causes exist, including tumors and structural skeletal abnormalities.
Patients with any of the problems listed above may be good candidates for brachial plexus surgery if their nerves don’t heal on their own, particularly if they experience severe pain, weakness, and reduced quality of life due to poor arm, hand, and shoulder function.
The Role of Diagnostic Imaging and Testing
Diagnostic imaging is essential for evaluating brachial plexus injuries accurately. MRI and CT scans provide detailed views of the nerve structure, helping Dr. Ko determine the optimal treatment approach.
In addition, nerve conduction studies and electromyography (EMG) measure nerve function, revealing areas of damage and indicating how well signals are transmitted.
Brachial Plexus Nerve Grafting vs.Transfer: The Differences
Nerve reconstruction surgery for brachial plexus injuries often involves two main techniques: nerve grafting and nerve transfer.
In nerve grafting, a piece of nerve from another part of the body bridges the gap between the injured nerve ends, promoting regeneration and function restoration.
Nerve transfer involves rerouting a functioning nerve from a less crucial area to restore movement or sensation in the affected area.
In some cases, Dr. Ko may incorporate muscle transfer in a nerve reconstruction procedure. With a muscle transfer, he moves a portion of a functional muscle from another part of your body to an area where the muscle has withered due to a brachial plexus injury.
Pediatric Nerve Reconstruction Procedures
In children, brachial plexus injuries often stem from birth complications. While many children spontaneously recover in the first month or two of life, others experience ongoing problems with arm and hand function.
Generally, pediatric nerve reconstruction procedures are scheduled in the first six months of life, possibly up to 9 months of age. The earlier, the better is the general rule when it comes to restoring a child’s function after a brachial plexus birth injury. Earlier treatment increases the chances of a baby having a full recovery, with maximum arm, hand, and shoulder strength and movement.

Success Rates and Prognosis for Nerve Reconstruction
Nerve reconstruction success varies based on the extent of nerve damage, type of procedure, and timing of the surgery. Early intervention typically improves outcomes, with the optimal treatment window occurring within six months of the injury.
Many patients experience substantial restoration of movement and sensation; however, full recovery may take months to years, and some residual deficits can remain.
The long-term prognosis is generally better for younger patients with less severe injuries.
Managing Pain and Discomfort Post-Surgery
Postoperative pain management strategies include medications, physical therapy, and sometimes nerve blocks to ease discomfort. In severe cases, Dr. Ko may recommend specialized pain management interventions.
Factors Influencing Nerve Healing and Regeneration
Nerve healing takes time. Age, injury severity, and surgical timing all influence healing. Younger patients have enhanced healing abilities, so their nerves may regenerate faster.
The distance from the injury site to the muscle also affects healing, as longer distances require more regeneration. Proper rehabilitation is essential to support the body’s natural healing processes.
FAQs
What Are the Symptoms of Brachial Plexus Injuries?
Symptoms may include weakness, numbness, tingling, or loss of shoulder, arm, or hand movement. Severe injuries can lead to total paralysis in the affected limb.
What Is Recovery Like After Nerve Reconstruction?
Recovery varies, but it often involves months of physical therapy. Patience is crucial, as nerve regrowth is gradual, and function returns over time. Slow and steady wins the race.
Are There Risks With Nerve Reconstruction Surgery?
Like any surgery, nerve reconstruction has risks like infection, bleeding, or incomplete recovery of function. However, advances in surgical techniques have minimized complications.
Dr. Ko is a master surgeon who uses highly specialized techniques for nerve reconstruction, ensuring patients have the best chance of recovery with the lowest risk level possible.
How Long Does It Take To Regain Function After Surgery?
The nerves regrow very slowly but steadily. You can expect some improvements within months, but full recovery may take years, especially if nerves must regrow over long distances.
What Is Nerve Transfer, and When Is It Used?
Nerve transfer involves redirecting a healthy nerve to a damaged area. It’s used when nerve grafting isn’t feasible, often yielding faster results for restoring movement.
Is Physical Therapy Necessary After Nerve Reconstruction?
Yes, physical therapy is essential for maximizing recovery. Dr. Ko recommends starting a physical therapy regimen shortly after your surgery to help you regain strength and flexibility in your affected arm and hand.
Physical therapy is one of the best ways to support your healing nerves so they can function optimally again.
What Are the Long-Term Outcomes of Brachial Plexus Surgery?
Outcomes depend on age, injury severity, and surgery timing. Many patients experience significant functional improvements, though some may have lingering weakness or numbness. The earlier you seek treatment for your symptoms, the better your prognosis can be.
