The wrist is a complex and vital anatomical structure, essential for the functionality of the hand and arm. Its range of motion and robustness are fundamental for performing a wide range of daily activities, from typing to lifting weights. However, precisely because of its constant exposure to stress and loads, wrist pain is an extremely common problem that can affect individuals of all ages and lifestyles. Understanding the causes of wrist pain, associated symptoms, diagnostic methods, and treatment options is crucial for effective management and complete recovery. This article, based on over thirty years of clinical experience, aims to provide an exhaustive guide on this condition, offering an in-depth and evidence-based overview.

Introduction

Wrist pain is discomfort in the joint connecting the forearm to the hand, presenting with varying severity from mild aching to sharp pain that may limit movement. Wrist pain can manifest in multiple forms, from a mild and intermittent discomfort to an acute and debilitating pain that seriously compromises quality of life. The underlying causes are equally varied, ranging from acute traumas such as fractures and sprains, to chronic conditions related to repetitive use, to inflammatory or degenerative pathologies. Ignoring wrist pain or self-diagnosing can lead to a worsening of the condition and a longer, more complex recovery. Therefore, a timely evaluation by a doctor or physical therapist is always recommended to identify the specific cause and undertake the most appropriate therapeutic path.

Functional Anatomy of the Wrist

To understand the causes of pain, it is useful to have a basic knowledge of wrist anatomy. The wrist is a complex joint that connects the forearm (composed of the radius and ulna) to the hand (composed of eight small carpal bones). These bones are arranged in two rows: the proximal row (scaphoid, lunate, triquetrum, pisiform) and the distal row (trapezium, trapezoid, capitate, hamate).

Numerous robust ligaments stabilize these bones, allowing a wide range of movements (flexion, extension, radial and ulnar deviation, circumduction) while maintaining structural integrity. Tendons (connecting forearm muscles to the fingers and thumb), nerves (such as the median, ulnar, and radial nerves), and blood vessels also pass through the wrist. The complex interaction between bones, ligaments, tendons, and nerves makes the wrist an extremely versatile structure but also vulnerable to injuries and pathologies.

Common Causes of Wrist Pain

The causes of wrist pain are numerous and can be classified into different categories.

Acute Trauma

Trauma is one of the most frequent causes of acute wrist pain, often resulting from falls onto an outstretched hand or direct impacts.

Fractures

• Distal Radius Fracture: This is the most common wrist fracture, often caused by a fall onto an outstretched hand. It can range from a simple crack to a complex fracture with displacement. Symptoms include intense pain, swelling, visible deformity, and functional limitation.
• Scaphoid Fracture: The scaphoid bone is one of the most frequently fractured carpal bones, also typically following a fall onto an outstretched hand. Its peculiarity lies in its limited vascularization, which can make healing slow and, if not treated correctly, lead to pseudoarthrosis (non-union) and osteoarthritis. Pain is often localized at the base of the thumb and may initially be underestimated.
• Other Carpal Fractures: Less common but possible, they can involve other carpal bones.

Sprains and Ligamentous Injuries

A wrist sprain occurs when the ligaments that stabilize the carpal bones are stretched or torn.

• Scapholunate Ligament Injury: This ligament is crucial for the stability of the proximal carpal row. An injury to it can lead to carpal instability, chronic pain, and, in the long term, osteoarthritis. Pain is often localized dorsally and may be associated with a “click” or “snap” during movement.
• Triangular Fibrocartilage Complex (TFCC) Injuries: The TFCC is a complex structure on the ulnar side of the wrist, which stabilizes the distal radioulnar joint and cushions loads. Injuries can be traumatic (e.g., fall on the wrist in hyperextension and ulnar deviation) or degenerative. Symptoms include pain on the ulnar side of the wrist, often aggravated by forearm rotation or loading.

Overuse and Repetitive Strain Pathologies

These conditions develop due to repetitive movements, incorrect postures, or excessive loads that stress tendons, nerves, and other structures.

Carpal Tunnel Syndrome (CTS)

It is a compression neuropathy of the median nerve that passes through the carpal tunnel, a narrow passage in the wrist. It is often associated with repetitive hand and wrist movements, pregnancy, hypothyroidism, or other medical conditions. Symptoms include tingling, numbness, and pain in the thumb, index, middle, and half of the ring finger, often worse at night. It can progress to muscle weakness and thenar eminence atrophy.

De Quervain’s Tendinitis

Also known as De Quervain’s tenosynovitis, it is an inflammation of the tendons of the abductor pollicis longus and extensor pollicis brevis and their sheaths, which pass through a fibro-osseous tunnel on the radial side of the wrist. It is common in people who perform repetitive thumb and wrist movements (e.g., new mothers, manual laborers). Pain is localized at the base of the thumb and radiates towards the forearm, aggravated by thumb movements and gripping.

Flexor or Extensor Tendinitis

Inflammation of the tendons that control finger and wrist flexion or extension. These conditions are often related to overuse or repetitive movements. Pain is localized along the path of the inflamed tendon and worsens with specific movement.

Synovial Ganglion

A benign cyst filled with synovial fluid that typically forms on the back of the wrist, but can also appear on the palmar side. The exact cause is not always clear, but it can be associated with microtrauma or joint degeneration. It is often asymptomatic, but can cause pain if it compresses nerves or adjacent structures, or if it is large enough to limit movement.

Degenerative and Inflammatory Conditions

Osteoarthritis

Osteoarthritis is a degenerative joint condition characterized by cartilage wear. In the wrist, it can affect several joints:

• Thumb Basal Joint Osteoarthritis (Trapeziometacarpal Osteoarthritis): Affects the trapeziometacarpal joint, causing pain at the base of the thumb, weakness in grip, and difficulty with activities requiring pinching.
• Scapholunate Osteoarthritis: A consequence of an untreated ligamentous injury or scaphoid pseudoarthrosis.
• Post-traumatic Osteoarthritis: Can develop years after a fracture or severe wrist ligament injury.

Rheumatoid Arthritis and other Inflammatory Arthritides

Rheumatoid arthritis is a chronic autoimmune disease that can affect the wrist joints, causing inflammation, pain, swelling, stiffness (especially in the morning), and, over time, joint deformities. Other forms of arthritis, such as psoriatic arthritis or gout, can also manifest with wrist pain.

Kienböck’s Disease

A rare condition characterized by avascular necrosis (death of bone tissue due to lack of blood supply) of the lunate bone. The cause is not always clear, but it can be associated with repeated trauma or a variation in the length of the radius and ulna. Symptoms include chronic wrist pain, stiffness, and weakness.

Other Causes

• Referred Cervical Problems: Wrist pain can sometimes be referred pain from problems in the cervical spine, such as disc herniations or foraminal stenosi (restringimento del canale vertebrale o vascolare)s, which compress the nerve roots innervating the arm and hand.
• Peripheral Neuropathies: In addition to carpal tunnel syndrome, other neuropathies can cause pain and altered sensation in the wrist, such as ulnar or radial nerve compression.

Symptoms Associated with Wrist Pain

The symptoms accompanying wrist pain can vary significantly depending on the underlying cause. An accurate description of symptoms is fundamental for a correct diagnosis.

• Type of Pain: It can be acute and sharp (often associated with trauma), dull and constant, burning (typical of nerve problems), or throbbing.
• Location: Pain can be diffuse or localized to a specific point (e.g., radial side for De Quervain’s, ulnar side for TFCC, center for carpal fractures).
• Radiation: Pain can radiate to the forearm, fingers, or thumb.
• Aggravating/Alleviating Factors: Pain may worsen with specific movements (e.g., gripping, rotation, flexion/extension), with loading, at night, or after a period of inactivity.
• Swelling and Redness: Signs of inflammation or trauma.
• Stiffness: Difficulty moving the wrist, especially in the morning.
• Weakness: Difficulty gripping objects or maintaining a hold.
• Tingling, Numbness, or Altered Sensation: Often indicative of nerve compression.
• Clicking, Crepitus, or Locking: May indicate joint, ligamentous, or tendinous problems.
• Deformity: Visible in cases of severe fractures or dislocations.

Diagnosis of Wrist Pain

The diagnosis of wrist pain requires a systematic approach that combines anamnesis, physical examination, and, if necessary, instrumental investigations.

Anamnesis and Physical Examination

The doctor or physical therapist will gather detailed information about the patient’s clinical history, including:

• Mode of Onset: Traumatic or gradual.
• Nature and Location of Pain: As described above.
• Work and Recreational Activities: To identify risk factors related to repetitive use.
• Pre-existing Medical Conditions: Such as diabetes, arthritis, hypothyroidism.
• Medications Taken.

The physical examination includes:

• Inspection: Evaluation of swelling, redness, deformity, muscle atrophy.
• Palpation: Identification of specific painful points, masses (e.g., ganglia), warmth.
• Mobility Assessment: Measurement of active and passive range of motion of the wrist and fingers.
• Strength Tests: Evaluation of grip strength and specific muscles.
• Neurological Tests: Evaluation of sensation and reflexes.
• Special Tests: Specific maneuvers to elicit symptoms and identify the involved structure (e.g., Finkelstein’s test for De Quervain’s, Phalen’s and Tinel’s tests for carpal tunnel syndrome, axial compression test for TFCC).

Instrumental Investigations

Depending on the suspected diagnosis, the following investigations may be requested:

• X-ray (RX): Useful for identifying fractures, dislocations, signs of osteoarthritis, or other bone abnormalities. It is often the first investigation requested in case of trauma.
• Ultrasound: Excellent for visualizing soft tissues such as tendons, ligaments, nerves, and synovial cysts. It can detect tendon inflammation (tendinitis) or nerve compressions.
• Magnetic Resonance Imaging (MRI): Provides detailed images of bones, cartilage, ligaments, tendons, and nerves. It is particularly useful for diagnosing complex ligamentous injuries (e.g., scapholunate ligament, TFCC), avascular necrosis (e.g., Kienböck’s disease), or tumors.
• Electromyography (EMG) and Nerve Conduction Velocity (NCV): These tests measure the electrical activity of muscles and the speed at which nerves transmit impulses. They are fundamental for confirming and quantifying the severity of compression neuropathies, such as carpal tunnel syndrome.
• Computed Tomography (CT): Offers very detailed bone images, useful for evaluating complex fractures, pseudoarthrosis, or for surgical planning.

Treatment of Wrist Pain

The treatment of wrist pain depends on the underlying cause, the severity of symptoms, and the individual needs of the patient. The goal is to reduce pain, restore function, and prevent recurrence.

Conservative Approach

Most wrist conditions respond well to a conservative approach.

• Rest and Activity Modification: Avoiding activities that aggravate pain is the first step. This does not mean total immobilization, but rather modifying movements or postures.
• Ice/Heat: Applying ice can help reduce inflammation and swelling in acute phases. Heat can be useful for relaxing muscles and improving circulation in chronic conditions.
• Pharmacotherapy: The doctor or physical therapist may prescribe non-steroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation, analgesics for pain control, or, in some cases, corticosteroids (oral or injectable) for more severe inflammation.
• Splints and Orthoses: The use of a splint or orthosis can immobilize or stabilize the wrist, providing rest to injured structures and reducing pain. Specific splints exist for different conditions (e.g., carpal tunnel syndrome splint, De Quervain’s splint).

Physiotherapy Treatment

Physiotherapy plays a central role in the recovery from wrist pain, both in acute and chronic phases, and after surgery.

• Manual Therapy: The physical therapist can use joint mobilization techniques to restore normal mobility of the wrist and carpal joints, massage and myofascial release techniques to reduce muscle tension and improve circulation.
• Instrumental Physical Therapies: Can be used to aid the healing process. These include laser therapy (to reduce pain and inflammation), ultrasound (to promote tissue repair), tecartherapy (to stimulate microcirculation and drainage), and in some cases shockwave therapy (for chronic tendinopathies). The effectiveness of these therapies must always be evaluated in a specific clinical context and supported by evidence.
• Therapeutic Exercises: A personalized exercise program is fundamental.

• Mobility Exercises: To restore the full range of motion of the wrist and fingers.

• Stretching Exercises: To stretch tight muscles and tendons, improving flexibility.

• Strengthening Exercises: To strengthen the muscles of the forearm, wrist, and hand, improving stability and load-bearing capacity. These may include the use of light weights, resistance bands, or rehabilitation balls.

• Proprioceptive Exercises: To improve awareness of the wrist’s position in space and coordination, essential for preventing future injuries.
• Postural and Ergonomic Re-education: The physical therapist will evaluate the patient’s postures and movements during daily and work activities, providing advice to modify the work environment (e.g., chair height, keyboard and mouse position) and task execution techniques to reduce stress on the wrist.
• Patient Education: Providing the patient with a clear understanding of their condition, pain self-management strategies, and the importance of adherence to the exercise program is crucial for lasting recovery.

Invasive and Surgical Treatment

In some cases, when conservative treatment is not sufficient or the condition is particularly severe, more invasive options may be considered.

• Injections: Injections of corticosteroids or hyaluronic acid directly into the joint or tendon sheath can provide temporary relief from pain and inflammation.
• Surgical Intervention: It is reserved for specific conditions such as:

• Unstable or complex fractures requiring reduction and fixation.

• Severe carpal tunnel syndrome with progressive neurological deficits.

• Significant ligamentous injuries causing chronic instability.

• Advanced osteoarthritis causing severe pain and functional limitation.

• Symptomatic and recurrent synovial ganglia.

• De Quervain’s tenosynovitis refractory to conservative treatment.

The decision to proceed with surgery is always made by the specialist doctor, after careful evaluation and discussion with the patient.

Prevention of Wrist Pain

Prevention is fundamental for maintaining wrist health and reducing the risk of pain onset or recurrence.

• Ergonomics: Adapt the work environment and computer workstations to keep the wrist in a neutral position. Use ergonomic keyboards and mice, wrist rests, and adjust chair and monitor height.
• Regular Stretching and Strengthening Exercises: Maintain flexibility and strength of forearm and wrist muscles with specific exercises.
• Breaks and Activity Variation: If performing repetitive activities, take frequent breaks for stretching and change wrist position. Alternate different tasks to avoid overloading specific muscle groups.
• Correct Lifting Techniques: Use both hands to lift heavy objects and distribute the load. Avoid excessively bending the wrist during lifting.
• Listen to Your Body: Do not ignore the first signs of pain or discomfort. Early intervention can prevent the worsening of the condition.
• Maintain a Healthy Lifestyle: A balanced diet and regular physical exercise contribute to the overall health of joints and connective tissues.
