Carpal Tunnel vs Cubital Tunnel: Key Differences (2026)

Carpal tunnel syndrome compresses the median nerve at the wrist. Cubital tunnel syndrome compresses the ulnar nerve at the elbow. Both cause numbness and tingling in the hand, but the pattern, location, and specific fingers affected are distinctly different. Misidentifying which condition you have can mean months of the wrong treatment — costing you time, money, and unnecessary symptoms.

What Is Carpal Tunnel Syndrome

Cross-section anatomical diagram of the carpal tunnel at the wrist showing the median nerve being compressed
The carpal tunnel is a narrow passage on the palm side of the wrist. Nine tendons and the median nerve share this space — making the nerve vulnerable to pressure.

Carpal tunnel syndrome (CTS) is the most common nerve compression condition in the upper extremity, affecting roughly 3-6% of adults. It occurs when the median nerve is compressed as it travels through the carpal tunnel — a narrow passage formed by the bones of the wrist (carpals) below and the transverse carpal ligament above.

The carpal tunnel also houses nine flexor tendons that slide through the same space. Anything that reduces the available room — swelling, inflammation, or structural changes — increases pressure inside the tunnel and compresses the median nerve. This nerve controls sensation to the thumb, index finger, middle finger, and half of the ring finger, as well as movement of the thumb's base muscles (thenar muscles).

Classic Carpal Tunnel Symptoms

  • Numbness or tingling in the thumb, index, middle, and ring fingers (not the little finger)
  • Symptoms often worse at night — many patients wake with a "dead hand"
  • Electric shock sensations shooting into the thumb, index, and middle fingers
  • Weakness in thumb grip and difficulty with fine motor tasks like buttoning
  • Pain radiating from the wrist up into the forearm, and sometimes the shoulder
  • Symptoms relieved by shaking the hand ("flick sign")

What Is Cubital Tunnel Syndrome

Anatomical diagram of the cubital tunnel at the elbow showing ulnar nerve compression and the cubital tunnel retinaculum
The ulnar nerve passes through the cubital tunnel on the inner side of the elbow — the same nerve responsible for the "funny bone" sensation when you hit your elbow.

Cubital tunnel syndrome is the second most common nerve compression condition in the upper extremity, accounting for roughly 10-15% of all upper limb nerve compression cases. It occurs when the ulnar nerve is compressed at the cubital tunnel — a narrow passage on the inner side of the elbow formed by the elbow bone (olecranon), the humerus, and the cubital tunnel retinaculum.

The cubital tunnel retinaculum is thin and flexible, so the tunnel size changes significantly with elbow flexion — the retinaculum stretches and the tunnel narrows. This is why cubital tunnel symptoms are often triggered or worsened by keeping the elbow bent, such as when holding a phone, driving, or sleeping with the elbow flexed.

Classic Cubital Tunnel Symptoms

  • Numbness and tingling in the ring finger and little finger (ulnar nerve distribution)
  • Pain and tenderness on the inner side of the elbow
  • Weakness in grip strength and difficulty with fine motor tasks
  • A "clawing" appearance of the ring and little fingers in advanced cases
  • Symptoms worsened by prolonged elbow flexion — especially during sleep
  • Electric shock-like sensations when the inner elbow is bumped (the "funny bone" sensation)

Nerve Anatomy: Why Location Changes Everything

Comparison infographic showing the median nerve pathway through the carpal tunnel and the ulnar nerve pathway through the cubital tunnel
The median nerve originates from the neck (C5-T1 nerve roots) and travels through the arm to the wrist. The ulnar nerve originates from the same nerve roots but takes a different path through the inner arm and elbow.

Understanding the anatomy explains every clinical difference between these two conditions. The median and ulnar nerves start in the neck at the same nerve roots (C5-T1) but take entirely different routes through the arm.

The Median Nerve (Carpal Tunnel)

The median nerve travels down the front of the arm, passes through the carpal tunnel at the wrist, and innervates:

  • Sensory: Thumb, index finger, middle finger, and the radial half of the ring finger (the half closest to the thumb)
  • Motor: The thenar muscles at the base of the thumb (opponens pollicis, abductor pollicis brevis, flexor pollicis brevis — the muscles that allow you to grip and pinch)

The median nerve does not give off branches above the wrist. This means the site of compression in carpal tunnel syndrome is always the wrist — and the symptoms always reflect wrist-level compression.

The Ulnar Nerve (Cubital Tunnel)

The ulnar nerve travels down the inner arm, passes behind the medial epicondyle of the humerus at the elbow, and then continues into the hand through Guyon's canal. It innervates:

  • Sensory: The little finger and the ulnar half of the ring finger (the half closest to the little finger)
  • Motor: The intrinsic hand muscles (interossei, lumbricals 3 and 4, adductor pollicis)

The ulnar nerve is particularly vulnerable at the elbow because it passes through a relatively exposed position behind the medial epicondyle — the bony point on the inner side of your elbow. Direct pressure against a hard surface, or prolonged elbow flexion, can compress it easily.

Double Crush Syndrome

An important clinical concept is double crush syndrome — the idea that compression at one site makes a nerve more vulnerable to compression at another site. A patient with a cervical disc problem (C6-C7) may have a mildly compromised median nerve that then develops carpal tunnel syndrome more easily. Similarly, a patient with mild cubital tunnel compression may develop carpal tunnel symptoms on top of it. Both sites must sometimes be evaluated and treated simultaneously.

Symptoms: Where the Patterns Diverge

Diagram showing finger sensory distribution for median nerve versus ulnar nerve with color coding for easy identification
Knowing which fingers are affected is the single most reliable way to distinguish carpal tunnel from cubital tunnel syndrome without special tests.

The symptoms of carpal tunnel and cubital tunnel syndromes overlap enough to cause confusion — but a careful look at the pattern almost always reveals the correct diagnosis.

Carpal Tunnel: The Median Nerve Pattern

Carpal tunnel syndrome causes symptoms in the median nerve distribution — the thumb, index finger, middle finger, and the half of the ring finger closest to the middle finger. The little finger is always spared.

Night symptoms are a hallmark of carpal tunnel syndrome. The wrist tends to flex unconsciously during sleep, further narrowing the carpal tunnel. Patients commonly report waking with a numb, tingling hand that they "shake out." Many describe the hand feeling swollen or stiff in the morning.

Thenar weakness develops in more advanced cases. Patients notice difficulty gripping, opening jars, or performing pinching movements. The thumb may feel weak when trying to oppose against resistance. In severe, long-standing cases, visible wasting of the thenar muscles (the rounded muscle mass at the base of the thumb) occurs — this is a serious sign requiring prompt treatment.

Provocative activities include typing, texting, gripping a steering wheel, knitting, playing guitar, or any activity that requires prolonged wrist flexion or extension. Symptoms often develop gradually and may be initially intermittent.

Cubital Tunnel: The Ulnar Nerve Pattern

Cubital tunnel syndrome causes symptoms in the ulnar nerve distribution — the little finger and the half of the ring finger closest to the little finger. The thumb and index finger are spared.

Elbow pain and tenderness is the most distinguishing feature. Pain is localised to the inner side of the elbow and may radiate down the forearm. Bumping the inner elbow (striking the "funny bone") produces an exaggerated, painful electric shock — because the nerve is exposed and directly vulnerable at this location.

Finger clawing occurs in advanced cubital tunnel syndrome. The ring finger and little finger adopt a claw-like posture because the intrinsic hand muscles that flex the finger knuckles are weakened. The fingers appear to hyperextend at the knuckles while the end joints curl.

Weakness in grip and finger spread is common. Patients may notice they cannot hold a cup as firmly, struggle with tasks requiring finger abduction (spreading the fingers apart), or drop objects. The ability to cross the fingers is often impaired.

Sleep-related symptoms are classic for cubital tunnel syndrome. Keeping the elbow bent during sleep — a common position when curling up — narrows the cubital tunnel and compresses the ulnar nerve. Many patients report being woken by numbness and tingling in the ring and little fingers.

When Both Conditions Occur Together

Patients with severe symptoms affecting both nerve distributions — or bilateral hand symptoms — should be evaluated for double crush syndrome. This is not rare: patients with significant carpal tunnel syndrome may have concurrent ulnar nerve involvement. A thorough clinical examination and nerve conduction studies can clarify whether one or both conditions are present.


Causes and Risk Factors

Infographic showing risk factors and causes for carpal tunnel syndrome versus cubital tunnel syndrome side by side
Many risk factors are shared, but the mechanical triggers for each condition differ based on the anatomical site of compression.

Carpal Tunnel Syndrome: Causes and Risk Factors

Repetitive hand and wrist movements are the most commonly cited trigger, particularly activities involving prolonged wrist flexion, extension, or gripping. Assembly line work, computer keyboarding, meat packing, and musical instrument playing are all associated with higher rates of carpal tunnel syndrome. Research published in the Journal of Orthopaedic & Sports Physical Therapy has consistently found dose-response relationships between repetitive hand work and CTS incidence.

Anatomical factors play a significant role. A smaller carpal tunnel size is largely genetically determined. Women have smaller carpal tunnels on average, which partly explains the higher prevalence in females. Bone spurs from arthritis, cysts, or swelling from wrist fractures can also narrow the tunnel.

Systemic medical conditions that increase CTS risk include:

  • Diabetes mellitus (affects nerve health and increases tissue swelling)
  • Hypothyroidism (causes fluid retention and tissue swelling)
  • Rheumatoid arthritis and other inflammatory conditions
  • Pregnancy (causes fluid retention and swelling in the carpal tunnel)
  • Obesity
  • Kidney disease (causes fluid imbalance)

Ergonomic factors at the workstation amplify risk. A keyboard and mouse setup that keeps the wrist in sustained flexion or deviation places the median nerve under prolonged pressure. Using a vertical mouse that keeps the wrist in a neutral position can significantly reduce this risk. Our best wrist brace for carpal tunnel covers additional support options.

Cubital Tunnel Syndrome: Causes and Risk Factors

Prolonged elbow flexion is the primary mechanical trigger for cubital tunnel syndrome. The cubital tunnel narrows by approximately 50% when the elbow is fully bent. This is why symptoms are common during driving, phone use, desk work with a resting elbow on an armrest, and sleep.

Direct pressure on the inner elbow compresses the ulnar nerve against the medial epicondyle. Leaning on elbows at a desk, resting the inner elbow on a car window, or sleeping with pressure on the inner elbow are all documented triggers.

Repetitive elbow flexion and extension can inflame the ulnar nerve or surrounding tissues, contributing to compression. Construction work, plumbing, and activities requiring frequent elbow movement are occupational risk factors.

Anatomical variations affect susceptibility. Some people have a shallow ulnar groove (the groove behind the medial epicondyle where the nerve runs) or retained muscle slips that compress the nerve. These variations are congenital and increase baseline vulnerability.

Systemic risk factors for cubital tunnel syndrome include:

  • Diabetes mellitus
  • Hypothyroidism
  • Inflammatory arthritis
  • Prior elbow fracture or dislocation
  • Prolonged IV infusion or catheterisation (in hospital settings)

How Each Condition Is Diagnosed

Flowchart showing the clinical diagnostic process for carpal tunnel and cubital tunnel syndrome including physical exam tests and investigations
A structured clinical examination can identify the affected nerve in most cases — nerve conduction studies confirm the diagnosis when results are equivocal.

Clinical Examination

A structured clinical examination by an experienced clinician can identify the affected nerve in the majority of cases without requiring specialised testing.

For carpal tunnel syndrome, clinicians use these provocation tests:

The Tinel's test involves tapping lightly over the carpal tunnel at the wrist. A positive test produces tingling in the median nerve distribution (thumb, index, middle fingers) — a sensation called "tingling on percussion."

The Phalen's test involves holding the wrists in forced flexion (pressing the backs of the hands together) for 60 seconds. A positive test reproduces or worsens the numbness and tingling in the median nerve distribution.

The carpal compression test involves applying direct pressure over the carpal tunnel with the examiner's thumb for 30 seconds. Reproduction of symptoms suggests median nerve compression.

For cubital tunnel syndrome, clinicians use these tests:

The Tinel's sign at the elbow involves tapping over the ulnar nerve as it passes behind the medial epicondyle. Tingling in the ring and little fingers is a positive test.

The elbow flexion test involves holding the elbow in full flexion (bent at 135 degrees or more) while the wrist is held in neutral. Numbness or tingling in the ulnar two fingers within 60 seconds is a positive test — this is the most sensitive clinical test for cubital tunnel syndrome.

The muscle weakness assessment evaluates grip strength, finger spread, and pinch strength. Wasting of the first dorsal interosseous muscle (the muscle between thumb and index finger on the back of the hand) is a specific sign of advanced cubital tunnel syndrome.

Nerve Conduction Studies and Electromyography

Nerve conduction studies (NCS) and electromyography (EMG) are the gold standard for confirming nerve compression and grading its severity. These tests measure:

  • Distal motor latency: How long it takes the nerve signal to travel across the compressed site
  • Conduction velocity: How fast the nerve conducts along its length
  • Amplitude: The strength of the nerve signal — reduced amplitude suggests axonal damage

For carpal tunnel syndrome, NCS shows prolonged distal sensory and motor latencies of the median nerve at the wrist. The test can grade severity as mild, moderate, or severe based on how slowed the conduction is.

For cubital tunnel syndrome, NCS shows slowed conduction velocity across the elbow segment of the ulnar nerve. The test may also show conduction block (the signal fails to cross the elbow entirely in severe cases) or reduced amplitude from axonal loss.

These tests are particularly valuable when:

  • The clinical picture is unclear (overlapping symptoms)
  • Both conditions may be present (double crush)
  • Surgery is being considered (severity grading informs decision-making)
  • Legal or workers' compensation documentation is required

Imaging

Plain X-rays of the wrist or elbow may be ordered if bony abnormalities (arthritis, bone spurs, old fractures) are suspected as contributing factors. MRI is not routinely required but may be used in complex cases or when masses (cysts, tumours) are suspected.


Treatment Options Compared

Visual guide comparing conservative and surgical treatment options for carpal tunnel versus cubital tunnel syndrome
Both conditions follow a stepwise treatment approach, but the specific interventions and surgical thresholds differ based on the nerve and compression site.

Conservative Treatment: First-Line for Both

Both carpal tunnel and cubital tunnel syndromes respond to conservative management in their early stages. The key is addressing symptoms promptly before significant nerve damage occurs.

For carpal tunnel syndrome:

Night splinting is the single most effective conservative intervention. A wrist splint that holds the wrist in a neutral position (not flexed, not extended) prevents the unconscious wrist flexion that occurs during sleep and triggers nocturnal symptoms. Splints should be worn for a minimum of 3-4 weeks. For recommendations, see our best wrist brace for carpal tunnel.

Activity modification involves adjusting workstations, changing how repetitive tasks are performed, and taking frequent breaks. A vertical mouse can significantly reduce median nerve stress during computer work — see our full vertical mouse recommendations.

Anti-inflammatory medications (ibuprofen, naproxen) can reduce swelling around the nerve for patients with intermittent symptoms. Corticosteroid injections into the carpal tunnel provide short-to-medium term relief and are particularly useful for pregnant patients or those seeking to delay surgery.

For cubital tunnel syndrome:

Night splinting with the elbow in extension (straightened) is the most effective conservative measure. A posterior splint (bracing the back of the elbow) that prevents more than 45-60 degrees of flexion during sleep can eliminate the primary provocative position. These splints are available online or through occupational therapy.

Activity modification focuses on avoiding prolonged elbow flexion and pressure on the inner elbow. Using a headset instead of cradling a phone, adjusting desk armrests to avoid resting the inner elbow, and avoiding leaning on elbows are practical changes that reduce symptoms significantly.

Nerve gliding exercises — gentle movements that stretch and glide the ulnar nerve through its natural range — can help reduce nerve adherence and improve symptoms when prescribed by a hand therapist. These exercises must be taught correctly to avoid aggravating the nerve.

When Surgery Is Needed

Carpal tunnel surgery is indicated when:

  • Conservative treatment fails after 3-6 months
  • Nerve studies show significant compression
  • Thenar muscle wasting is present (indicates advanced compression)
  • Constant numbness or severe symptoms are present

Carpal tunnel release involves cutting the transverse carpal ligament to relieve pressure on the median nerve. The procedure can be performed open (2-3 cm palm incision) or endoscopically (one or two small incisions). Both techniques achieve the same long-term result; endoscopic surgery typically allows a faster return to daily activities. Our complete carpal tunnel surgery recovery guide covers everything you need to know about the procedure and post-operative period.

Cubital tunnel surgery is indicated more readily than carpal tunnel surgery because:

  • Conservative management is less reliably effective at the elbow
  • The nerve is more exposed and vulnerable to ongoing mechanical stress
  • Prolonged elbow flexion during sleep is difficult to avoid permanently

Surgical options for cubital tunnel syndrome include:

  • Simple decompression: Releasing the cubital tunnel retinaculum to create more space for the nerve
  • Medial epicondylectomy: Removing part of the medial epicondyle to decompress the nerve
  • Anterior transposition: Moving the ulnar nerve to the front of the elbow (in front of the medial epicondyle) so it is no longer stretched or compressed during elbow flexion

The choice of procedure depends on the patient's anatomy, severity, surgeon preference, and whether prior surgery has been performed.

Recovery Comparison

Stage Carpal Tunnel Surgery Cubital Tunnel Surgery
Return to light activities 1-2 weeks (endoscopic) / 2-3 weeks (open) 2-3 weeks
Return to desk work 2-4 weeks 3-6 weeks
Driving 1-2 weeks 2-4 weeks
Heavy manual work 6-12 weeks 8-12 weeks
Full recovery 2-4 months 3-6 months

Recovery and Prognosis

Recovery trajectories differ between the two conditions — cubital tunnel surgery typically requires a longer and more careful rehabilitation period.

Carpal Tunnel Syndrome: Expected Outcomes

With appropriate treatment, carpal tunnel syndrome has an excellent prognosis. Conservative treatment resolves symptoms in approximately 25-30% of mild cases within 6 months. Surgery is successful in 70-90% of cases, with the majority of patients experiencing meaningful symptom improvement.

Night symptoms — the hallmark complaint — typically resolve first, often within days to weeks of surgery or starting splinting. This is the change patients notice most immediately.

Numbness resolves more gradually, particularly if it has been present for a long time. Full sensory recovery after significant pre-operative nerve damage can take 6-12 months as the nerve regenerates at approximately 1 mm per day.

Grip and pinch strength return gradually over 3-6 months after surgery. Pre-operative muscle wasting (thenar atrophy) may not fully reverse, especially if it has been present for more than a year before surgery.

Recurrence rates after carpal tunnel release are low — under 10% at 5 years — provided underlying systemic factors (diabetes, hypothyroidism) are well controlled.

For a comprehensive look at the recovery process after surgery, including what you can and cannot do at each stage, see our detailed carpal tunnel surgery recovery guide.

Cubital Tunnel Syndrome: Expected Outcomes

Cubital tunnel syndrome has a generally favourable prognosis with treatment, but recovery is often slower than with carpal tunnel syndrome, particularly after surgery.

Conservative treatment success is more variable for cubital tunnel than carpal tunnel. Many patients achieve meaningful improvement with night splinting and activity modification, but others find the night-time elbow flexion difficult to control permanently. Studies suggest approximately 40-60% of patients with mild to moderate cubital tunnel syndrome improve with conservative care alone.

After surgery, the timeline for nerve recovery is longer. The ulnar nerve is a mixed sensory and motor nerve with longer regeneration distances, and post-operative scar tissue at the elbow can delay recovery. Patients typically see progressive improvement in symptoms over 6-12 months.

Residual symptoms are more common after cubital tunnel surgery than carpal tunnel surgery. Mild persistent numbness in the little finger, particularly during cold weather or with prolonged pressure on the elbow, can persist in some patients even after successful decompression.

Complication rates are low for both surgeries, but cubital tunnel surgery has a slightly higher rate of complications including scar tenderness, persistent elbow stiffness, and (rarely) nerve instability where the nerve moves abnormally after transposition.

What Affects Recovery in Both Conditions

  • Duration of symptoms before treatment: Longer symptom duration before treatment = longer recovery and lower chance of full reversal
  • Severity of nerve compression at diagnosis: Severe cases with significant axonal damage take longer to recover
  • Age: Older patients tend to recover more slowly
  • Comorbidities: Diabetes and thyroid disease slow nerve regeneration
  • Smoking: Impairs microcirculation and delays nerve healing
  • Compliance with post-treatment recommendations: Night splinting, activity modification, and hand therapy all significantly improve outcomes

Prevention Strategies

Practical prevention guide showing ergonomic setup changes for both carpal tunnel and cubital tunnel syndrome prevention
Prevention focuses on reducing mechanical stress at each compression site — wrist neutral for carpal tunnel, elbow extension for cubital tunnel.

Preventing Carpal Tunnel Syndrome

Ergonomic workstation setup is the foundation of prevention for desk workers. Keep the keyboard and mouse at a height that allows the wrist to remain in a neutral position — not bent up or down. A vertical mouse that keeps the forearm in a pronated but neutral position significantly reduces median nerve strain compared to a standard mouse. An external keyboard with a negative tilt (back of the keyboard higher than front) also promotes wrist neutrality.

Take regular breaks from repetitive tasks. The American Academy of Orthopaedic Surgeons recommends taking brief breaks every 30-60 minutes from keyboard work and performing gentle wrist stretches. Wrist flexion and extension stretches and median nerve glides are easy to perform at your desk.

Manage systemic risk factors where possible. Keeping diabetes well-controlled, treating hypothyroidism, maintaining a healthy weight, and avoiding tobacco use all reduce CTS risk. If you are pregnant and experiencing carpal tunnel symptoms, wrist splinting at night is safe and effective — symptoms typically resolve after delivery.

Use proper technique during manual work. Avoid prolonged gripping with the wrist in flexion. Use tools with larger, padded handles that distribute pressure more evenly across the palm.

Preventing Cubital Tunnel Syndrome

Avoid prolonged elbow flexion — this is the single most important prevention measure. When working at a desk, adjust armrests so your elbows are not constantly bent. Avoid cradling your phone between your ear and shoulder.

Minimise pressure on the inner elbow. Avoid leaning on your inner elbows, resting your arm on car windows, or sitting with pressure on the inner elbow against a desk or table. A soft elbow pad over the ulnar nerve area can provide protection for those who must rest their elbows during work.

Sleep with the elbow extended. Use a night splint or simply be mindful of sleeping position. Many people sleep with elbows bent to 90 degrees or more; consciously straightening the elbows during sleep can prevent nocturnal ulnar nerve compression. Some patients find a pillow tucked alongside the arm useful for maintaining a straighter sleeping position.

Adjust car seat position for drivers who spend long hours behind the wheel. A seat position that requires sustained elbow flexion to reach the steering wheel can aggravate cubital tunnel symptoms. Adjust the seat to minimise this.

For broader nerve health, maintaining adequate vitamin B12 levels, managing blood sugar, and avoiding nutritional deficiencies that impair nerve function supports all peripheral nerves — including the median and ulnar nerves.

FAQ: Carpal Tunnel vs Cubital Tunnel

What is the main difference between carpal tunnel and cubital tunnel syndrome?

The primary difference is which nerve is compressed. Carpal tunnel syndrome involves compression of the median nerve at the wrist, inside the carpal tunnel. Cubital tunnel syndrome involves compression of the ulnar nerve at the elbow, inside the cubital tunnel. This difference determines which fingers go numb, where pain is felt, and which treatment approach is needed.

How can I tell if I have carpal tunnel vs cubital tunnel syndrome?

The key distinguishing factor is which fingers are affected. Carpal tunnel syndrome causes numbness in the thumb, index, middle, and half of the ring finger — the median nerve distribution. Cubital tunnel syndrome causes numbness in the ring finger and little finger — the ulnar nerve distribution. Cubital tunnel also causes elbow tenderness and pain behind the elbow, while carpal tunnel causes wrist and palm pain.

Can you have both carpal tunnel and cubital tunnel syndrome at the same time?

Yes, it is possible to have both conditions simultaneously — this is called double crush syndrome. Having compression at one site can make the nerve more vulnerable to compression at another site. Patients with severe or bilateral hand symptoms should be evaluated for both conditions. Diagnosis requires separate nerve conduction studies for each site.

Which condition is more common — carpal tunnel or cubital tunnel?

Carpal tunnel syndrome is significantly more common. It affects approximately 3-6% of the adult population, making it one of the most prevalent nerve compression conditions. Cubital tunnel syndrome is the second most common upper extremity nerve compression, affecting roughly 1-2% of adults. Both conditions are more prevalent in women and people who perform repetitive manual work.

What are the treatment differences between carpal tunnel and cubital tunnel syndrome?

Both conditions start with conservative treatment: activity modification, splinting, and ergonomic changes. Carpal tunnel responds well to night wrist splints and typically requires surgery only for moderate to severe cases. Cubital tunnel often requires avoiding elbow flexion during sleep (with a splint) and may resolve with conservative care, but surgery is more frequently needed when symptoms are persistent. Surgical procedures differ significantly — carpal tunnel release at the wrist versus cubital nerve decompression or transposition at the elbow.
