De Quervain’s tenosynovitis is a condition caused by inflammation of the tendons at the base of the thumb, which affects the smooth lining of the tendons, called the synovium, and leads to pain, swelling, and restricted movement.
Normally, the tendons glide effortlessly through small compartments in the wrist, but when the synovium becomes inflamed, this movement becomes uncomfortable and difficult. The condition is commonly associated with repetitive thumb or wrist movements and can interfere with everyday activities, such as grasping objects or rotating the wrist.
Symptoms of De Quervain’s Tenosynovitis
Symptoms are typically aggravated by specific thumb or wrist movements and may vary in severity depending on the duration of the condition. In more advanced cases, even minor thumb or wrist movements can cause discomfort.
Common symptoms include:
- Pain near the base of the thumb: Discomfort may extend up the forearm and tends to worsen during activities like pinching or grasping
- Swelling on the thumb side of the wrist: Swelling may be visible near the wrist joint, sometimes accompanied by fluid-filled cysts at the base of the thumb
- Difficulty moving the thumb and wrist: Tasks involving thumb motion or gripping can become increasingly difficult and uncomfortable
- Snapping or catching sensation: A clicking or snapping feeling may occur when moving the thumb, often due to tendon restrictions caused by swelling or thickening of the tendon sheath
Causes and Risk Factors
De Quervain’s tenosynovitis is often caused by repetitive stress or strain on the thumb tendons, with several contributing factors.
- Repetitive hand movements: Actions such as typing, gardening, or lifting a child using the thumb for leverage can strain the tendons over time, irritating the tendon sheath and leading to thickening and restricted movement
- Direct injury to the wrist or thumb: Trauma such as a wrist fracture can increase stress on the tendons or result in scar tissue formation that impairs tendon movement
- Inflammatory conditions: Disorders such as rheumatoid arthritis may raise the likelihood of developing this condition by affecting tendon health
- Hormonal changes: Pregnancy and breastfeeding are associated with a higher risk, possibly due to hormonal fluctuations affecting the elasticity of tendons and ligaments
Diagnosing De Quervain’s Tenosynovitis
Diagnosis is made primarily through physical examination by an orthopaedic or plastic surgeon with subspecialty training in hand and wrist conditions, with assessment focusing on swelling, tenderness, and restricted thumb movement.
Physical Examination
A physical examination is performed to assess for swelling, tenderness, and limitation in thumb movement. In some cases, fluid-filled cysts at the base of the thumb may also be visible during examination.
Clinical Test
The most commonly used clinical test involves the patient folding the thumb across the palm, closing the fingers into a fist, and tilting the wrist toward the little finger side. Reproduction of pain near the base of the thumb during this manoeuvre is a recognised indicator of De Quervain’s tenosynovitis.
Imaging Studies
X-rays or MRI scans may be requested to exclude other conditions that can cause similar symptoms, such as arthritis, fractures, or other structural abnormalities in the wrist. Imaging is not always required for straightforward presentations and is at the discretion of the examining specialist.
Treatment Options for De Quervain’s Tenosynovitis
Treatment focuses on relieving pain, reducing inflammation, and improving function. Non-surgical options are generally considered first, with surgical management reserved for cases where conservative treatment has not provided adequate relief.
Non-Surgical Treatment
Rest and Activity Modification
Avoiding repetitive thumb and wrist movements is an important step in reducing strain on the tendons. This may involve altering daily activities, taking regular breaks during tasks that aggravate symptoms, and adjusting lifting techniques, for example, scooping rather than gripping when lifting a child. Rest is often supported by splinting to allow the tendons to recover.
Splinting
A thumb spica splint is used to stabilise the wrist and thumb, limiting the movements that irritate the inflamed tendons. The splint helps maintain the thumb in a neutral position, reducing strain and supporting the healing process. A custom-fitted splint from a hand therapist is designed to accommodate individual anatomical needs, providing a specialised alternative to generic over-the-counter options.
Non-steroidal anti-inflammatory drugs such as ibuprofen or naproxen may help manage pain and swelling associated with De Quervain’s tenosynovitis. These are available over the counter or may be prescribed for short-term use. A doctor or pharmacist can advise on the most appropriate option based on individual circumstances.
Corticosteroid Injections
A corticosteroid injection directly into the affected tendon sheath may provide relief from pain and inflammation. In addition to reducing swelling, the injection can help soften the tendon sheath, which may improve tendon movement and reduce friction in the area. A specialist will assess whether this treatment is appropriate based on the individual’s symptoms and response to other management approaches.
Surgical Treatment
Tendon Sheath Release
When non-surgical treatments have not provided adequate relief, a surgical procedure may be considered to release the tight tendon sheath. The procedure involves a small incision near the affected area to create more space for the tendons to move freely. It is typically performed as day surgery under local anaesthesia, and most patients can return home the same day. A specialist will discuss whether surgery is appropriate based on the nature and duration of your symptoms.
Recovery After Surgery
Recovery progresses in stages, with individual timelines varying depending on occupation and the demands of daily life.
- Weeks 1–2: The thumb spica splint remains in place until suture removal; gentle thumb and wrist movements are encouraged early to support healing.
- Weeks 2–6: Swelling resolves gradually; progressive strengthening exercises, including grip and thumb opposition movements, begin once wound healing is confirmed.
- Return to work: Desk-based workers may resume work within approximately two weeks with temporary modifications; those in manual occupations are likely to require a longer period before returning to full duties.
- Ongoing rehabilitation: A structured hand therapy programme, guided by an occupational therapist or physiotherapist with advanced training in hand rehabilitation, supports the recovery of grip strength and functional movement.
Prevention and Management
Taking steps to reduce repetitive strain on the thumb tendons may help prevent the condition from developing or recurring.
Movement and Ergonomics
Avoiding sustained or repetitive thumb and wrist movements and taking regular breaks during activities that place strain on the hands is an important preventive measure. Maintaining a neutral wrist position during tasks, particularly at a workstation, helps minimise tendon stress. Where possible, ergonomic tools and modified lifting techniques can reduce the load placed on the thumb tendons during daily activities.
Exercises
Gentle exercises may be introduced during the recovery phase, once sharp pain has settled. These may include slow wrist bends and gentle thumb-to-fingertip movements to help restore range of motion. Exercises should only be started on the advice of a specialist or hand therapist, as beginning too early may aggravate symptoms.
When to Seek Professional Assessment
The following symptoms may warrant assessment by a doctor:
- Pain near the base of the thumb lasting more than two weeks despite rest
- Visible swelling on the thumb side of the wrist
- A clicking or snapping sensation during thumb movement
- Increasing difficulty gripping objects or performing daily tasks involving the thumb or wrist
- Symptoms that worsen over time or do not improve with activity modification
Asked Questions
Does De Quervain’s tenosynovitis resolve without treatment?
In mild cases, the condition may gradually improve with sufficient rest and by avoiding activities that aggravate symptoms. However, most cases benefit from timely medical assessment to guide appropriate management and support full recovery.
Can De Quervain’s tenosynovitis recur after treatment?
The condition may recur if repetitive strain, improper hand and wrist positioning, or the activities that contributed to its initial development continue after treatment. Ergonomic modifications and movement adjustments to both hands may help reduce this risk.
Can pregnancy-related cases be resolved after childbirth?
In many instances, symptoms may improve after childbirth as hormone levels stabilise and the physical demands on the thumb tendons, such as frequent lifting, decrease. A specialist can advise on management options during and after pregnancy.
What happens if De Quervain’s tenosynovitis is left unmanaged?
Without appropriate management, symptoms may worsen over time, making everyday tasks such as gripping, typing, or lifting increasingly difficult. Long-term tendon irritation may lead to stiffness and ongoing functional limitations. Early assessment allows treatment to be started promptly, which generally supports better outcomes.
What should I avoid with De Quervain’s tenosynovitis?
During the symptomatic period, it is generally advisable to avoid forceful gripping, pinching, or wringing motions; lifting heavy objects with the wrist in an awkward position; and repetitive thumb movements such as prolonged scrolling on a mobile phone. If an activity causes pain, stopping and resting the hand is recommended.
Is a corticosteroid injection painful?
The injection itself is brief, and the area is numbed with local anaesthetic to minimise discomfort. Patients often describe a short “pinch” or “sting” during administration. A specialist will explain what to expect and discuss whether this treatment is appropriate before proceeding.
Is surgery for De Quervain’s tenosynovitis a major procedure?
The procedure is generally considered minor and is performed as day surgery, most often under local anaesthesia. The surgeon makes a small incision to release the tight tunnel around the tendons. A specialist will discuss the procedure in detail, including expected recovery, before any decision is made.
Next Steps
If you are experiencing pain near the base of the thumb, a snapping or catching sensation during thumb movement, or increasing difficulty with gripping or daily tasks involving the wrist, consider speaking with a hand surgeon for an assessment and guidance on appropriate management options.
