Carpal Tunnel Syndrome Treatment
Carpal tunnel syndrome is the most common nerve compression in the body, and it has one symptom that distinguishes it from nearly everything else. It wakes people up. Patients describe shaking the hand out at three in the morning to get the feeling back, night after night, frequently for months before mentioning it to anyone.
Steven Struhl, MD is board certified in orthopedic surgery and separately in sports medicine and arthroscopic surgery, serves on the faculty of NYU School of Medicine, and has practiced in New York since 1991. Nerve compression is one of the conditions where waiting carries a real cost, because a nerve compressed long enough produces muscle changes that do not fully reverse.
Carpal Tunnel Syndrome Symptoms
- Numbness in the Thumb, Index, and Middle Fingers: the distribution of the median nerve, with the little finger characteristically spared.
- Night Symptoms: waking with numbness or burning and shaking the hand for relief, which is close to diagnostic.
- Tingling While Driving or Holding a Phone: positions that hold the wrist bent for a period.
- Dropping Things: a loss of fine control and grip that patients frequently attribute to clumsiness.
- Weak Pinch: difficulty with buttons, keys, and jar lids.
- Aching Into the Forearm: which sometimes radiates upward and confuses the picture.
- Wasting at the Base of the Thumb: a late sign, and a serious one.
Numbness that has become constant, or visible loss of muscle bulk at the base of the thumb, means the compression has been present long enough to cause damage. Recovery after surgery at that stage is real but incomplete, which is the reason to treat this before it gets there.
Why the Median Nerve Gets Compressed
The carpal tunnel is a fixed space, bounded by the wrist bones on three sides and a thick ligament across the front, with nine tendons and the median nerve passing through it. Anything that increases the volume inside it or reduces the space compresses the nerve.
- Repetitive Hand Use: particularly with force, vibration, or sustained wrist flexion.
- Wrist Position: prolonged bending, which raises pressure inside the tunnel substantially.
- Pregnancy: fluid retention, which frequently resolves after delivery.
- Diabetes and Thyroid Disease: both increasing susceptibility.
- Rheumatoid Arthritis: inflaming the tendon sheaths within the tunnel.
- Prior Wrist Fracture: altering the anatomy of the tunnel.
- Anatomy: some people simply have a smaller tunnel, which is why the condition runs in families.
How Carpal Tunnel Syndrome Is Diagnosed
The examination tests sensation in the median nerve distribution, checks strength in the thumb muscles the nerve supplies, and uses provocative tests that reproduce the symptoms, including tapping over the nerve and holding the wrist bent. Nerve conduction studies and electromyography measure how much the nerve is slowed and whether the muscle has been affected, which both confirms the diagnosis and grades its severity. Those studies also help separate carpal tunnel from a neck problem or from cubital tunnel syndrome, which affects the other side of the hand. Radiographs are taken where arthritis or an old fracture may be contributing.
Non Surgical Treatment
Mild and intermittent symptoms frequently respond well, and this is the right starting point for most patients.
- Night Splinting: a neutral wrist splint worn overnight, which is the single most effective non surgical measure and the one most patients underuse.
- Activity Modification: reducing sustained flexion, vibration, and forceful repetitive gripping.
- Ergonomic Changes: keyboard, mouse, and workstation adjustments.
- Anti Inflammatory Medication: for associated aching.
- Corticosteroid Injection: placed into the tunnel, which relieves symptoms in a majority of patients and is also informative, since a good response predicts a good result from surgery.
- Treating Contributing Conditions: thyroid disease, diabetes control, and inflammatory arthritis.
Carpal Tunnel Release Surgery
Surgery is indicated for symptoms that persist despite non surgical treatment, for constant numbness, and for any weakness or muscle wasting, where it should not be delayed. Dr. Struhl performs carpal tunnel release as an outpatient procedure, usually under local anesthesia with sedation.
- Open Release: a small incision in the palm, through which the transverse carpal ligament is divided, relieving pressure on the nerve.
- Endoscopic Release: performed through one or two smaller incisions using a camera, with a slightly faster early recovery and equivalent results at a year.
- What Is Actually Done: the ligament forming the roof of the tunnel is cut, which enlarges the space permanently. The nerve itself is not operated on.
- Recurrence: uncommon, since the ligament does not reform in a way that recreates the compression.
Recovery After Carpal Tunnel Release
- First Few Days: a light dressing, with finger motion encouraged immediately and the hand elevated.
- Weeks One to Two: light use of the hand resumed, with night symptoms frequently improving within the first week.
- Weeks Two to Six: grip strength rebuilding, with tenderness in the palm at the incision, which is expected and settles.
- Weeks Six to Twelve: return to heavier work and full grip strength.
- Months Three to Twelve: numbness continuing to improve as the nerve recovers, which is slow by nature.
Night symptoms usually resolve quickly and dramatically, which is the change patients notice first. Numbness improves over months. Where wasting was present beforehand, some deficit frequently remains.
Schedule a Carpal Tunnel Consultation in New York City
Numbness that has stopped coming and going, or any weakness in the thumb, is worth evaluating promptly rather than managing with a splint indefinitely, because what recovers depends on how long the nerve has been compressed. Dr. Struhl evaluates wrist and hand conditions at his Manhattan and Westchester offices. Contact us to schedule an appointment.
