Wrist and Hand Conditions — Tendon and Nerve Issues

Wrist & Hand · The wrist and hand pack more small joints, tendons, and nerves into a small space than almost any other body region, enabling fine motor control at the cost of frequent overuse injury.

Quick answers

What is carpal tunnel syndrome?

Carpal tunnel syndrome is compression of the median nerve as it passes through a narrow tunnel on the palm side of the wrist, producing numbness, tingling, and sometimes weakness in the thumb, index, and middle fingers.

What is De Quervain's tenosynovitis?

De Quervain's tenosynovitis is irritation of the tendons on the thumb side of the wrist, often associated with repetitive gripping or thumb use, and is a common cause of pain near the base of the thumb.

Does typing cause carpal tunnel syndrome?

Research on keyboard use as an isolated cause of carpal tunnel syndrome is mixed; wrist position, overall repetitive hand use, and individual anatomical factors are all thought to contribute.

Can wrist splints help with nerve compression?

Night-time wrist splinting in a neutral position is commonly recommended for mild to moderate carpal tunnel syndrome and is supported by several clinical guidelines as an early conservative measure.

What is trigger finger?

Trigger finger is a condition in which a finger tendon catches within its sheath, causing the finger to click, lock, or require extra effort to straighten after bending.

When does carpal tunnel syndrome need surgery?

Surgical release is typically considered when symptoms are severe, when there is measurable nerve damage on testing, or when conservative measures have not provided adequate relief.

Start with this section - Common problems

Wrist and hand conditions are dominated by overuse-related tendon and nerve problems, reflecting how frequently the hands are used for repetitive daily and occupational tasks.

Less commonly, the region is affected by joint degeneration, ganglion cysts, or trauma-related fractures, each requiring a distinct diagnostic and management approach.

Common problems

Mild–moderate

Carpal tunnel syndrome

Compression of the median nerve within the carpal tunnel, producing numbness, tingling, and sometimes weakness in the thumb, index, and middle fingers, often worse at night.

Mild–moderate

De Quervain's tenosynovitis

Irritation of the thumb-side wrist tendons, commonly associated with repetitive gripping or lifting tasks involving thumb use.

Mild–moderate

Trigger finger

Catching or locking of a finger tendon within its sheath, producing a clicking sensation or temporary inability to fully straighten the finger.

Mild–moderate

Wrist sprain

Stretching or tearing of wrist ligaments, commonly from a fall onto an outstretched hand, ranging from mild strain to more significant ligament injury.

Mild

Ganglion cyst

A benign, fluid-filled sac forming near wrist joints or tendons, often noticed as a soft lump that may or may not be painful.

Moderate

Thumb base osteoarthritis

Degenerative change at the joint where the thumb meets the wrist, more common with advancing age, producing pain and reduced strength with pinching and gripping.

Because several of these conditions can produce overlapping symptoms such as pain with gripping, distinguishing between them typically relies on the specific location of symptoms and targeted physical examination findings.
