HAND & WRIST SUBLUXATION: THE GRIP ANCHOR

Why "Carpal Tunnel" and Grip Weakness Start in the Bones, Not the Nerves

The Hand is the ultimate tool of human evolution. Composed of 27 distinct bones—8 carpals in the wrist, 5 metacarpals in the palm, and 14 phalanges in the fingers—it is a marvel of dexterity and strength.

However, the hand is also the most abused structure in the modern body. From typing on keyboards to gripping handlebars (mountain biking) and using smartphones, the delicate Carpal Bones of the wrist are constantly subjected to repetitive micro-trauma.

When a carpal bone subluxates (usually the Lunate or Scaphoid), the "Tunnel" collapses. The result is often misdiagnosed as purely "soft tissue" Carpal Tunnel Syndrome. Patients wear braces and take anti-inflammatories, but the pain persists because the roof of the tunnel has physically collapsed onto the nerve.

At Spine Spot Chiropractic, we view the Hand not as a separate entity, but as the terminus of the upper extremity chain. If the wrist bones are not aligned, the grip fails.

THE ANATOMICAL ANCHOR: THE CARPAL ARCH

Biomechanics of the Wrist Complex

The wrist is not a hinge; it is a complex arch.

• The Carpal Tunnel: The floor of the tunnel is the carpal bones (specifically the Lunate and Capitate). The roof is the Transverse Carpal Ligament. If the Lunate bone slips forward (Anterior), it pushes directly into the tunnel, crushing the Median Nerve from the bottom up.
• The Grip Mechanism: Every time you squeeze your hand, the metacarpals must spread slightly. If a metacarpal head is fixated, the hand feels "stiff" and weak. The natural arch of the palm flattens out.
• Fixation vs. Pain: A Hand/Wrist Subluxation is uniquely frustrating.
• The "Lunate Anterior": This is the most common subluxation. It feels like a hard lump in the middle of the wrist crease. Pushing on it sends electric shocks into the thumb and index finger.
• The "Dropped Scaphoid": The Scaphoid bone (at the base of the thumb) drops down. This causes sharp pain in the "Snuff Box" (the hollow at the base of the thumb) and makes opening jars impossible.

THE NEUROLOGICAL BLAST RADIUS

The Median, Ulnar, & Radial Nerves

The hand is innervated by three major nerves, all of which must pass through the wrist gauntlet.

The Median Nerve (The "Carpal Tunnel" Victim)

• The Connection: Passes through the center of the wrist.
• The Dysfunction: True Carpal Tunnel Syndrome.
• The Result: Numbness in the Thumb, Index, and Middle Finger. Patients often wake up at night shaking their hands out to "get the blood back." The weakness is specifically in the Thenar Eminence (the meaty part of the thumb).

The Ulnar Nerve (The "Cyclist's Palsy")

• The Connection: Passes through "Guyon's Canal" on the pinky side of the wrist (near the Pisiform bone).
• The Dysfunction: Handlebar Palsy / Ulnar Neuropathy.
• The Result: Numbness in the Pinky & Ring Finger. Often seen in cyclists who lean on their handlebars or office workers who rest their wrists on the desk edge. The Pisiform bone gets jammed, compressing the nerve.

The Radial Nerve (The Back of the Hand)

• The Connection: Runs along the thumb side of the wrist.
• The Dysfunction: De Quervain's Tenosynovitis (mimic).
• The Result: Wrist Drop / Thumb Pain. Weakness in extending the wrist or sharp pain when giving a "thumbs up." This is often linked to a subluxated Radial Head at the elbow (the kinetic chain).

THE ORGAN SYSTEM CONNECTION

Visceral Ramifications of Hand Displacement

While the hand does not contain organs, its reflex points are powerful.

• The Grip Strength (Heart Health): Grip strength is a surprisingly accurate predictor of overall cardiovascular health. If your grip is weak due to mechanical fixation, you are functionally deconditioned.
• The "Tech Neck" Loop: Hand pain changes posture. If your wrists hurt, you alter your shoulder position, rolling them forward. This worsens the strain on the C6/C7 nerves in the neck, creating a feedback loop of pain from neck to hand.
• The Ganglion Cysts: Mechanical irritation of the wrist joints often causes the body to produce excess synovial fluid, which bubbles out as a Ganglion Cyst ("Bible Bump"). This is a sign of chronic joint dysfunction, not just a random growth.

THE SYMPTOM MATRIX

"How Does It Feel?"

A Wrist fixation feels like your hand is "rusting."

The Hallmark: The "Night Shake" & Dropped Objects Waking up with a dead hand and having to shake it vigorously, combined with unexpectedly dropping coffee cups or keys.

Associated Symptoms:

• "Dead" Fingers: Numbness that feels like wearing a glove.
• Jar-Opening Failure: Sharp pain at the base of the thumb when twisting a lid.
• Keyboard Fatigue: Aching in the forearms after only 20 minutes of typing.
• Wrist Clicking: A sensation of bones "popping" or grinding when rotating the wrist.
• Morning Stiffness: Inability to make a tight fist upon waking.
• Elbow Pain: Pain radiating up the forearm (Tennis Elbow) because the wrist extensors are overworked stabilizing a loose wrist.

THE SPINE SPOT DIFFERENCE

Diagnosis & Correction: A Master-Craftsman Approach

The hand is intricate. "Pulling the finger" or simply shaking the hand is not a specific adjustment. At Spine Spot, Dr. James Fraser utilizes a mastery of multiple chiropractic techniques to analyze the 8 carpal bones individually and correct the specific architecture of your wrist.

PHASE 1: THE FORENSIC AUDIT

Before we touch your hand, we must visualize and quantify the interference using a comprehensive Neuromusculoskeletal Examination.

• Orthopedic Assessment: We perform Phalen’s Test (reverse prayer) and Tinel’s Sign (tapping the nerve) to differentiate between a collapsed carpal tunnel and nerve entrapment at the elbow or neck. We use Finkelstein’s Test to rule out tendonitis in the thumb.
• Dynamometer Testing: We measure your Grip Strength quantitatively. A significant difference between hands often indicates a neurological inhibition caused by a subluxated carpal bone (usually the Capitate).
• Static & Motion Palpation: Dr. Fraser meticulously palpates each of the 8 carpal bones individually. We check for the position of the Lunate (often slipped anterior) and the Scaphoid (often dropped inferior). We feel for the "hard end-feel" that signifies a bone is locked out of its proper arch.

PHASE 2: THE PRECISION ADJUSTMENT

Dr. Fraser is proficient in four distinct, high-level correction protocols for the Hand and Wrist. Depending on the fragility of the wrist, the presence of arthritis, and the direction of the misalignment, we will utilize one of the following:

The Gonstead Correction (The Carpal Lift)

• Best For: Anterior Lunate subluxations ("Carpal Tunnel") and restoring the carpal arch.
• The Setup: Seated (Extremity Board). The hand is supported firmly to isolate the wrist.
• The Contact: Dr. Fraser uses a specific reinforced thumb contact on the palmar surface of the Lunate or Scaphoid.
• The Vector: The thrust is a specific "whip" motion.
• Lunate: We extend the wrist and drive the bone A-P (Anterior to Posterior) to push it back into the floor of the tunnel.
• Scaphoid: We lift the bone I-S (Inferior to Superior) and lateral to reopen the joint space.
• The Release: The wrist adjustment is often a sharp, crisp "snap." Patients usually feel an immediate opening of the tunnel and a return of sensation to the fingertips.

Diversified Technique (The Traction Release)

• Best For: General wrist stiffness, jammed metacarpals, and "waking up" the hand.
• The Setup: Seated or Supine. Dr. Fraser grasps the patient's hand with a specific handshake grip.
• The Contact: Thumbs are placed on the dorsal aspect of the wrist (Radius/Ulna) while fingers secure the carpal rows.
• The Vector: A high-velocity, low-amplitude thrust delivered with Long Axis Traction. We distract the joint to separate the carpal rows and apply a quick impulse to realign the Capitate and Lunate simultaneously.
• The Release: A satisfying release that decompresses the entire wrist complex, instantly improving range of motion for typists and manual laborers.

Thompson Terminal Point (The Extremity Drop)

• Best For: Acute wrist pain, swelling, or patients who cannot tolerate the "snap" of a manual adjustment.
• The Setup: The patient's hand is placed on a specialized Extremity Drop Piece or "Speeder Board."
• The Contact: A specific contact on the prominent carpal bone (e.g., the Pisiform or Lunate).
• The Vector: Dr. Fraser applies a sharp thrust. The drop piece falls away, utilizing Newton’s laws of inertia to speed up the bone and set it back into place without heavy pressure.
• The Result: A vibration-based correction that is incredibly gentle yet structurally effective for reducing the "lump" in the wrist.

Activator Methods (The Instrument Precision)

• Best For: Isolating tiny carpal bones (like the Trapezium), treating arthritis (CMC joint), or highly sensitive patients.
• The Setup: Seated, utilizing isolation tests (thumb flexion/extension) to verify the exact bone involved.
• The Contact: The Activator instrument is placed directly on the individual carpal bone or metacarpal head.
• The Vector: The instrument delivers a lightning-fast (milliseconds) impulse. It is faster than the body's muscle reflex can guard against. The line of drive is strictly calculated to move the bone back into the arch.
• The Result: No "cracking." Just a precise neurological reset that communicates directly with the mechanoreceptors to restore grip strength.

PHASE 3: ADJUNCTIVE THERAPIES

• Class IV Cold Laser Therapy: We target the Carpal Tunnel directly to reduce the swelling of the flexor tendons and speed up nerve regeneration.
• Ergonomic Retraining: We assess your mouse/keyboard setup. Often, a vertical mouse is prescribed to take the twist out of the forearm (Pronation syndrome) and protect the adjustment.

RECLAIM YOUR GRIP

Stop the Numbness

If you are sleeping in wrist braces, dropping your phone, or living with constant tingling in your fingers, the issue is likely a subluxated Carpal Bone. The tunnel has collapsed.

Do not let a mechanical wrist problem force you into unnecessary surgery.

Restore the arch. Restore the dexterity.
