Carpal Tunnel Syndrome
Carpal tunnel syndrome is compression of the median nerve at the wrist, causing hand numbness, tingling, pain, and weakness that may improve with nerve decompression when non-surgical care is not enough.
Peripheral nerve pathway
From injury assessment to reconstruction
Diagnosis
Define the injured nerve, severity, timing, and pattern of weakness or pain.
Timing
Determine whether observation, urgent repair, or reconstruction is most appropriate.
Reconstruction plan
Choose repair, grafting, decompression, tumor surgery, or nerve transfer.
Recovery
Track regeneration, therapy progress, pain control, and functional return.
Time-sensitive repair
Early specialist review can preserve options for nerve repair, grafting, or transfer.
Anatomic diagnosis
Exam, imaging, EMG, and surgical history help define the level and severity of injury.
Function-first planning
Treatment is chosen around realistic goals for movement, sensation, pain, and independence.
Overview
Carpal tunnel syndrome is one of the most common peripheral nerve compression conditions. It occurs when the median nerve is compressed at the wrist as it passes through a narrow space called the carpal tunnel.
The median nerve provides sensation to the thumb, index, middle, and part of the ring finger. It also helps control important thumb muscles used for pinch and grip. When pressure on the nerve persists, symptoms can progress from intermittent numbness to constant sensory loss or thumb weakness.
Symptoms
- Numbness or tingling in the thumb, index, middle, or ring fingers
- Nighttime hand symptoms
- Hand pain that may travel up the arm
- Weak grip or dropping objects
- Thumb muscle weakness in advanced cases
- Symptoms with gripping, texting, typing, driving, tools, or vibration
- Difficulty handling buttons, coins, pens, or other small objects
Diagnosis & evaluation
Evaluation includes a focused exam and review of the symptom pattern, including which fingers are involved, whether symptoms wake the patient at night, and whether weakness or loss of dexterity is present. Examination may assess sensation, thumb strength, nerve irritability, and signs of other nerve or spine conditions.
Testing may include:
- EMG and nerve conduction studies to confirm median nerve compression, grade severity, and look for other nerve problems
- Ultrasound when nerve swelling or anatomy needs clarification
- X-rays or other imaging when arthritis, fracture, mass, or another wrist problem is suspected
The goal is to confirm that symptoms truly fit median nerve compression at the wrist before recommending surgery.
Treatment options
Mild or early cases may improve with nighttime wrist splinting, activity changes, ergonomic adjustment, therapy, or injections. Avoiding prolonged wrist flexion, tight gripping, vibration, and repeated forceful hand use can reduce irritation in some patients.
Surgery is considered when symptoms are severe, progressive, persistent despite non-surgical care, or associated with nerve damage on testing. Carpal tunnel release divides the tight ligament over the carpal tunnel to reduce pressure on the median nerve. Numbness may improve gradually as the nerve recovers; longstanding weakness or constant numbness may take longer and may not fully reverse.
Dr. Barone’s approach
Dr. Barone evaluates whether symptoms truly come from median nerve compression and whether surgery is likely to help, especially in patients with complex, severe, recurrent, or overlapping nerve compression. The decision is based on the symptom pattern, exam, testing, patient goals, and whether another diagnosis needs to be addressed first.
Frequently asked questions
What causes carpal tunnel syndrome? +
Carpal tunnel syndrome occurs when the median nerve is compressed at the wrist. This can cause numbness, tingling, nighttime symptoms, hand pain, and weakness.
What fingers are usually affected? +
Symptoms most often affect the thumb, index, middle, and part of the ring finger. The small finger is usually not the main problem in isolated carpal tunnel syndrome.
When is surgery considered? +
Surgery may be considered when symptoms are persistent, severe, worsening, associated with weakness, or not improving with splinting, activity changes, injections, or other non-surgical treatment.
What does carpal tunnel surgery do? +
Carpal tunnel release opens the tight ligament over the carpal tunnel to reduce pressure on the median nerve and allow the nerve to recover.
Can carpal tunnel symptoms come from something else? +
Yes. Cervical radiculopathy, peripheral neuropathy, arthritis, tendon problems, and other nerve compressions can mimic or overlap with carpal tunnel syndrome, which is why pattern-based evaluation matters.
