This is an overview of 10 common wrist problems. But, let’s start with a definition.
What is the Wrist?
The wrist is a complex, highly flexible joint that bridges the forearm and the hand. Rather than being a single simple hinge, it is formed by the articulation of the two forearm bones—the radius and ulna—with eight small, uniquely shaped carpal bones arranged in two rows.
The wrist structure relies on an intricate network of ligaments to maintain stability, alongside numerous tendons that cross the joint to allow for bending, straightening, and side-to-side tilting of the hand.
Internally, it contains specialised structures like the carpal tunnel, a narrow passageway on the palm side that houses key tendons and the median nerve, as well as a cushioning cartilage complex on the outer side that supports smooth, stable rotation of the forearm and hand.
What it is: Compression or squeezing of the median nerve as it travels through the carpal tunnel, a narrow passageway of ligament and bone on the palm side of your wrist. It is commonly triggered by repetitive hand movements, pregnancy, fluid retention, or underlying inflammation.
Common signs: Numbness, tingling, or a “pins and needles” sensation primarily in the thumb, index, middle, and half of the ring finger, which frequently worsens at night or while holding objects like a phone or steering wheel.
When to Worry:
The numbness becomes constant and no longer resolves with shaking out your hand or wearing a resting splint
You experience a noticeable loss of hand coordination, such as frequently dropping objects or struggling with buttons
You notice visible flattening or wasting of the muscular pad at the base of your thumb (thenar atrophy)
When to See a Doctor:
Soon. To confirm nerve compression via clinical tests or nerve conduction studies, and to discuss treatments like nocturnal splinting, steroid injections, or an operation.
What it is: Inflammation and swelling of the protective sheaths surrounding the specific tendons that run along the thumb side of the wrist. It is typically caused by chronic overuse, repetitive gripping, or forceful twisting movements of the wrist and thumb.
Common signs: Pain and tenderness localised to the base of the thumb and the side of the wrist, which intensifies significantly when making a fist, grasping objects, or turning the wrist.
When to Worry:
The pain becomes so severe that you cannot use your thumb for basic tasks like writing, typing, or lifting a kettle
You experience a catching, snapping, or locking sensation when moving your thumb
Localised swelling or a firm, painful lump develops on the thumb side of the wrist
When to See a Doctor:
Soon. Routine evaluation by a GP or Physiotherapist can help confirm the diagnosis and initiate treatments like specialised splinting, targeted exercises, or corticosteroid injections.
What it is: Non-cancerous, fluid-filled lumps that develop most frequently along the tendons or joints on the back or palm side of the wrist. They arise when tissues surrounding the joint bulge out, filling with a thick, jelly-like synovial fluid.
Common signs: A visible, smooth, and typically round or oval lump beneath the skin that can vary in size over time, sometimes changing or completely disappearing before returning.
When to Worry:
The cyst grows rapidly, causes a deep, persistent ache, or interferes with your normal wrist movement and flexibility
The lump presses on an underlying nerve, causing numbness, tingling, or weakness in your hand and fingers
The skin overlying the cyst becomes broken, irritated, or shows signs of localized infection
When to See a Doctor:
Routinely. Mainly for peace of mind. A doctor can confirm the lump is a benign ganglion cyst, which requires no treatment unless it causes significant pain or functional limitation.
What it is: The progressive degradation and loss of the smooth, protective cartilage that caps the bone surfaces within the wrist joint. It is most commonly secondary to a past wrist trauma, such as an old fracture or a severe ligament tear.
Common signs: A deep, dull ache within the wrist joint that intensifies during or after physical activity and is accompanied by progressive joint stiffness, swelling, and a grating sensation (crepitus).
When to Worry:
The joint becomes acutely swollen, hot, and red, which may indicate a flare-up or an inflammatory crystal arthropathy like gout
Your range of motion decreases drastically, preventing you from fully bending or straightening your hand
Pain persists throughout the night and fails to respond to standard over-the-counter anti-inflammatories
When to See a Doctor:
Routinely. Long-term conservative management can help maintain your wrist function and control pain through hand therapy, supportive splints, or medication.
What it is: A break in the scaphoid bone, one of the small carpal bones on the thumb side of the wrist. This injury is notoriously tricky, usually resulting from a heavy fall onto an outstretched hand (FOOSH).
Common signs: Deep pain and swelling localised specifically to the “anatomical snuffbox,” which is the small triangular depression at the base of the thumb when it is extended.
When to Worry:
This is always a situation to worry about. The scaphoid bone has a fragile, retrograde blood supply, meaning a missed fracture can easily lead to non-healing (non-union) or tissue death (avascular necrosis) of the bone.
You experience severe pain when attempting to grip objects or apply pressure to the thumb side of your wrist
When to See a Doctor:
Urgently. Go to a Minor Injuries Unit (MIU), Urgent Treatment Centre (UTC) or A&E immediately. Early x-rays, specialised splinting, or CT scanning are vital, as even a suspected scaphoid fracture often requires strict immobilisation.
What it is: A complete break of the larger forearm bone (radius) near its lower end close to the wrist joint, most frequently caused by a high-impact fall onto an outstretched arm.
Common signs: Severe, immediate pain accompanied by rapid swelling, deep bruising, and an obvious, crooked deformity of the wrist, traditionally described as a “dinner fork” appearance.
When to Worry:
This is always a critical situation. A displaced bone fragment can compress local nerves or permanently alter the mechanical alignment and long-term function of your hand.
Your fingers or hand look pale, feel cold to the touch, or develop a complete loss of sensation, suggesting a compromise to major blood vessels or nerves
The broken bone pierces through the skin, creating an open, high-risk surgical emergency
When to See a Doctor:
Urgently. Go to the nearest A&E department immediately. Realignment under local anesthesia (reduction) or surgical stabilisation with wires or plates is routinely required.
What it is: A tear or injury to the main stabilizing cartilage structure on the outer, little-finger side of the wrist joint. It can occur suddenly from a twisting injury or wear down gradually over time from repetitive loading.
Common signs: Pain localized to the outer edge of the wrist (ulnar side) that worsens when turning doorknobs, lifting heavy pans, or placing weight through the wrist during a push-up.
When to Worry:
You hear or feel a distinct, painful clicking, popping, or catching sensation inside the joint during normal forearm rotation
The outer side of your wrist feels chronically unstable, weak, or feels as though it might “give way” entirely
The pain is unremitting and stops you from performing basic daily gripping activities
When to See a Doctor:
Soon. A specialist assessment or an MRI scan is necessary to diagnose a TFCC tear and determine whether it requires tailored hand therapy, splinting, or keyhole surgery.
What it is: Microscopic tearing, irritation, and inflammation of one or more tendons crossing the wrist joint, stemming from repetitive movements, improper ergonomics, or prolonged typing and mouse use.
Common signs: A broad, dull ache or stiffness across the front or back of the wrist that develops gradually, often feeling worse during or immediately after a long work day.
When to Worry:
The ache transforms into a constant, sharp, or burning pain that persists even during prolonged rest periods
You experience a significant, measurable reduction in your manual grip or pinch strength
Simple adjustments to your workstation or resting provide absolutely no improvement over several weeks
When to See a Doctor:
Routinely. An early assessment by a GP or an occupational health physiotherapist can guide ergonomic alterations and exercises to stop chronic tendon degeneration.
What it is: A chronic, systemic autoimmune disease where the body’s immune system mistakenly attacks the lining of the joints, very frequently involving both wrists symmetrically.
Common signs: Persistent pain, swelling, and warmth in both wrists, accompanied by severe stiffness in the mornings that lasts for more than 30 minutes. Over time, it can cause visible joint deformities.
When to Worry:
The inflammation spreads rapidly to multiple smaller joints in your fingers or hands
You notice a progressive shifting, drifting, or structural misalignment of your fingers or wrist joint
The chronic swelling is accompanied by persistent systemic symptoms like fatigue, low-grade fevers, or unintended weight loss
When to See a Doctor:
Soon. Early referral to a Consultant Rheumatologist is essential to protect the joint structures from irreversible erosion using targeted disease-modifying therapies.
What it is: A rare, dangerous, and rapidly destructive bacterial infection within the fluid and tissues of the wrist joint, typically introduced via a deep puncture wound, local skin infection, or through the bloodstream.
Common signs: Sudden, agonising wrist pain accompanied by intense swelling, severe redness, and heat over the entire joint. The wrist is typically so painful that any attempt to move it even slightly is impossible.
When to Worry:
This is always a situation to worry about. If left untreated for even a day, bacterial enzymes can permanently destroy the delicate joint cartilage.
The joint symptoms are accompanied by systemic signs of sepsis, such as a high fever, shaking chills, a rapid heart rate, or confusion
When to See a Doctor:
Urgently. Go to the nearest A&E department immediately. This requires emergency admission for urgent surgical joint washout and high-dose intravenous antibiotics.
