Carpal Tunnel Syndrome

Carpal tunnel syndrome is the most commonly diagnosed peripheral nerve entrapment in the United States, affecting an estimated four to ten million Americans. The condition develops when the median nerve - one of the three major nerves that supply the hand - is compressed as it passes through the carpal tunnel, a narrow passageway on the palm side of the wrist formed by the carpal bones and the transverse carpal ligament. At Georgia Injury Network, Dr. Daniel Dierdorff provides conservative, non-surgical treatment for carpal tunnel syndrome that addresses both the wrist and the often-overlooked cervical spine component of the condition.

Anatomy of the Carpal Tunnel

The carpal tunnel is a rigid structure with no room for expansion. Nine flexor tendons and the median nerve all pass through this small channel, and any swelling, inflammation, or thickening of the tendon sheaths within the tunnel directly compresses the nerve. The median nerve controls sensation in the thumb, index finger, middle finger, and the thumb-side half of the ring finger. It also controls the thenar muscles at the base of the thumb that allow you to pinch and grip.

When the median nerve is compressed within this tunnel, the result is the characteristic constellation of symptoms that carpal tunnel patients know all too well.

Recognizing Carpal Tunnel Symptoms

Carpal tunnel syndrome typically develops gradually, with symptoms that initially come and go before eventually becoming constant:

Early Stage

• Numbness and tingling in the thumb, index, and middle fingers, particularly at night or upon waking
• A sensation of fingers being “swollen” even when no visible swelling is present
• The need to shake the hands upon waking to restore sensation (the “flick sign”)
• Intermittent tingling during activities that involve sustained wrist flexion - holding a phone, gripping a steering wheel, typing

Progressive Stage

• Numbness becomes more persistent, with sensation not fully returning between episodes
• Tingling and burning sensations extend up the forearm
• Grip strength begins to decline - dropping objects, difficulty turning keys or opening jars
• Fine motor tasks become harder - buttoning shirts, picking up small objects

Advanced Stage

• Constant numbness in the median nerve distribution
• Visible wasting (atrophy) of the thenar muscles at the base of the thumb
• Significant weakness that affects daily activities and work performance
• Permanent nerve damage if compression is not relieved

What Causes Carpal Tunnel Syndrome

Repetitive Use

The most common driver of carpal tunnel syndrome is repetitive motion of the wrist and fingers. Typing, mouse use, assembly line work, hair styling, dental hygiene, and any occupation that involves sustained or repetitive wrist positioning can inflame the flexor tendon sheaths within the carpal tunnel, creating progressive median nerve compression.

For College Park professionals who spend their days on computers in airport-area offices or along the I-85 and I-285 corridors, the combination of sustained keyboard use and mouse clicking creates a daily recipe for carpal tunnel development.

Wrist Position and Ergonomics

The carpal tunnel is most compressed when the wrist is fully flexed or fully extended. Working with the wrists bent - whether angled up on a keyboard, bent down while gripping tools, or flexed during sleep - reduces the available space in the tunnel and increases pressure on the median nerve. Improper workstation ergonomics is a primary contributor.

Underlying Health Conditions

Several health conditions increase susceptibility to carpal tunnel syndrome by reducing the available space within the tunnel or increasing the vulnerability of the median nerve:

• Pregnancy (fluid retention swells tissue within the tunnel)
• Hypothyroidism
• Diabetes (nerve tissue is more vulnerable to compression)
• Rheumatoid arthritis (inflammation of tendon sheaths)
• Obesity
• Prior wrist fracture or dislocation

The Cervical Connection

One of the most frequently overlooked factors in carpal tunnel syndrome is the role of the cervical spine. The median nerve originates from nerve roots at C6, C7, C8, and T1. If these nerve roots are even mildly compressed at the cervical spine level - from disc bulging, foraminal narrowing, or vertebral misalignment - the nerve’s overall tolerance for compression is reduced. A nerve that is already partially compromised at the neck is far more vulnerable to the additional compression it encounters at the carpal tunnel. This “double crush” phenomenon explains why many carpal tunnel patients fail to improve after wrist-focused treatment alone.

Dr. Dierdorff’s Treatment Approach

Cervical Spine Evaluation and Adjustment

Every carpal tunnel patient at Georgia Injury Network receives a cervical spine evaluation in addition to wrist examination. If cervical nerve root compression is contributing to the median nerve dysfunction, chiropractic adjustments to the cervical spine address the proximal component of the problem. Many patients who have failed other treatments for carpal tunnel respond when the cervical component is finally addressed.

Wrist and Carpal Bone Adjustment

The eight carpal bones that form the floor and walls of the carpal tunnel can shift subtly out of alignment, narrowing the tunnel and compressing the nerve. Dr. Dierdorff performs specific mobilization and adjustment techniques to restore proper carpal bone alignment, expanding the available space within the tunnel without surgery.

Nerve Gliding Exercises

Median nerve gliding exercises - sometimes called nerve flossing - gently mobilize the nerve through the carpal tunnel, breaking adhesions that may have formed between the nerve and surrounding structures. These exercises, performed regularly at home, are a critical component of both treatment and prevention.

Ergonomic Modification

Lasting resolution of carpal tunnel syndrome requires eliminating the repetitive stresses that created the condition. Dr. Dierdorff evaluates each patient’s work environment and daily activities, providing specific recommendations for wrist positioning, keyboard and mouse setup, tool modification, and activity pacing that reduce carpal tunnel pressure.

Night Splinting

Wearing a neutral-position wrist splint during sleep prevents the wrist from flexing into positions that compress the carpal tunnel - a position most people unconsciously adopt during the night. Night splinting alone can significantly reduce morning numbness and tingling.

Recovery Without Surgery

Studies published in the Journal of Manipulative and Physiological Therapeutics and the Annals of Internal Medicine have demonstrated that conservative management of carpal tunnel syndrome - including chiropractic adjustment, nerve gliding exercises, and ergonomic modification - produces outcomes comparable to surgical carpal tunnel release for mild to moderate cases. Surgery remains an option for severe or refractory cases, but many patients who are told surgery is their only option find that they recover fully with conservative care when both the wrist and the cervical spine are treated.
