De Quervain’s tenosynovitis is one of the most common sources of thumb and wrist pain that brings patients into Fort Orthopedic Hand Center. It affects the tendons that run along the thumb side of the wrist, and it can make ordinary tasks like opening a jar or lifting a coffee cup uncomfortable, painful, and difficult. The good news is that de Quervain’s responds well to conservative treatment, and most patients recover without surgery when the condition is caught and addressed appropriately.
What Is De Quervain’s Tenosynovitis?
De Quervain’s tenosynovitis is a condition in which the tendons on the thumb side of the wrist become irritated and inflamed, causing pain and swelling where the thumb meets the wrist. Two specific tendons are involved: the abductor pollicis longus (APL), which pulls the thumb away from the hand, and the extensor pollicis brevis (EPB), which extends the thumb. Together, these tendons are used in almost every pinching, gripping, and lifting motion the thumb makes. When the narrow tunnel through which these tendons pass becomes inflamed, the tendons can no longer glide freely. This restricted movement of the thumb produces friction, pain, and sometimes a catching or snapping sensation that is characteristic of de Quervain’s tenosynovitis.
Why the Condition Is Also Called “Mommy Thumb” or “Texting Thumb”: De Quervain’s has earned the name “mommy thumb” from its prevalence among new mothers, who spend significant time in the repetitive motion of lifting an infant, particularly with the wrists angled and thumbs extended outward. It’s also sometimes called “texting thumb” due to sustained smartphone use, with the thumb doing most of the work. Both names point to the same underlying pattern: repetitive thumb and wrist motions that overload the tendon sheath over time.
What Causes De Quervain’s?
De Quervain’s tenosynovitis develops when the tendon sheath becomes irritated through repeated or sustained stress, causing thickening and inflammation that restricts tendon movement. Causes include:
- Repetitive motion patterns: Activities that involve repetitive wrist and thumb movement, particularly those that combine a gripping motion with bending or twisting the wrist, place the most stress on the tendon tunnel. Common examples include lifting, knitting, golf, racquet sports, and extended keyboard or smartphone use.
- Pregnancy and new mothers: Hormonal changes during pregnancy increase fluid retention and ligament laxity, which can affect the tendon sheaths. After childbirth, the repeated motion of lifting, supporting, and breastfeeding an infant sustains that stress. De Quervain’s is particularly common in the first year after childbirth, and it often resolves when the repetitive loading decreases, though treatment usually speeds the recovery.
- Injury to the wrist or tendons: Direct injury to the thumb or wrist can also trigger de Quervain’s. Injury to these areas can lead to scar tissue formation, which limits tendon movement and increases the likelihood of inflammation and pain over time.
- Inflammatory arthritis: Inflammatory arthritis can directly cause de Quervain’s tenosynovitis.
Those at higher risk include:
- Arthritis: Patients with inflammatory arthritis, such as rheumatoid arthritis.
- Age: Individuals between the ages of 30 and 50.
- Sex: Women have a higher risk of de Quervain’s than men.
- Pregnant or new mothers: Hormonal changes and repeatedly lifting a young child.
- Repetitive hand or wrist movements: Jobs or hobbies that involve doing the same motions over and over (typing, playing piano, gardening, certain sports).
How to Recognize the Symptoms
The hallmark of de Quervain’s is pain along the thumb side of the wrist and at the base of the thumb. In many cases, a tender bump or mild swelling is visible in that area as well.
Pain and Tenderness at the Thumb’s Base: The pain of de Quervain’s typically worsens with thumb and wrist movement and with anything that loads the thumb, including pinching, gripping, twisting, or lifting. Many patients describe a dull, persistent ache at rest that becomes sharper with use of the thumb. In more developed cases, even light contact with the area produces discomfort.
The Finkelstein Test: The Finkelstein test is the standard clinical test for de Quervain’s tenosynovitis. To perform it, you curl your thumb into your palm, close your fingers over it, and then tilt the wrist toward the little finger side. In a patient with de Quervain’s, this motion stretches the irritated tendons and typically produces a sharp, characteristic pain at the base of the thumb. Dr. Fort uses this test as part of the initial examination, and a positive result is a strong diagnostic indicator.
When Symptoms Are Severe Enough to Seek Care: Mild de Quervain’s can sometimes improve with rest and activity modification alone, but most cases require some form of treatment to fully resolve. Seek evaluation if the pain is limiting your ability to carry out daily activities, if you’ve been managing symptoms on your own for more than a few weeks without improvement, or if the pain is waking you at night. Seek care promptly if you experience numbness or tingling in the thumb, sudden worsening of pain at rest, or swelling that extends up the forearm, as these may indicate additional nerve involvement or a more complex condition.
How De Quervain’s Is Diagnosed
De Quervain’s is primarily a clinical diagnosis, meaning it can usually be confirmed through a physical examination without imaging. Dr. Fort will examine the wrist for tenderness along the tendon tunnel, assess thumb and wrist range of motion, and perform the Finkelstein test. He will also assess for conditions that can present similarly, including arthritis at the base of the thumb (basal joint arthritis) and intersection syndrome, since the treatment approaches differ. X-rays may be performed to rule out other sources of pain, particularly arthritis or a fracture of the scaphoid bone. Occasionally, ultrasound may be used to show tendon sheath thickening, confirm an atypical case, or guide injection placement. MRI is rarely required.
Treatment Options: Conservative and Surgical
Most patients being treated for de Quervain’s improve without surgery. Treatment follows a stepwise approach, moving toward more intervention only when earlier steps have not produced sufficient relief.
Splinting and rest: A thumb splint can be used to immobilize the thumb and wrist, taking the irritated tendons off load so the inflammation can subside. Wearing the splint consistently, including during sleep, is important for it to be effective. Splinting is often the first recommendation for patients presenting with mild to moderate symptoms.
Activity modification: Avoiding repetitive thumb movements as much as possible is important for treating de Quervain’s. Similarly, you should avoid pinching or gripping with your thumb, especially while moving your wrist from side to side.
Comfort care: Applying ice to the thumb side of the wrist can reduce swelling and discomfort. Inflammation and pain relief medications such as ibuprofen may also be recommended to reduce pain and swelling.
Corticosteroid injections: A corticosteroid injection into the tendon tunnel is typically the fastest nonsurgical treatment available for de Quervain’s. It delivers anti-inflammatory medication directly to the inflamed sheath and often provides significant relief within one to two weeks. A second injection may be recommended if the first provides incomplete relief. Success rates are typically above 50 percent with just one injection, and can be 80 percent or higher with two injections. Dr. Fort will determine whether injection is appropriate based on the duration and severity of your symptoms.
Physical therapy: Therapeutic exercise and soft tissue techniques can support recovery after the acute inflammation has been addressed, helping to restore strength and reduce the likelihood of recurrence. Physical therapy is often combined with splinting or following an injection rather than used in place of it.
De Quervain’s release surgery: When conservative treatment has not resolved symptoms, typically after one or two injections and an adequate course of splinting, de Quervain’s release surgery is highly effective. The procedure is performed outpatient, usually under local anesthesia, and takes less than 30 minutes. Dr. Fort makes a small incision over the tendon tunnel and opens the tendon sheath, releasing the restriction and allowing the tendons to move freely again. Patients who undergo de Quervain’s release surgery report high satisfaction rates, and the condition rarely recurs once the sheath has been opened.

Dr. Nicholas M. Fort, MD, FAAOS (Fellow of the American Academy of Orthopaedic Surgeons), is a fellowship-trained orthopedic hand surgeon with a practice focused on conditions of the hand, wrist, and elbow. De Quervain’s tenosynovitis is among the most common conditions he evaluates and treats, and the full range of treatment options, from splinting and injection through surgical release, are available in his Miami practice.
At your appointment, Dr. Fort will evaluate your thumb and wrist, confirm the diagnosis, and recommend the treatment approach most appropriate for where your symptoms currently stand. If you’ve already tried splinting or over-the-counter options without noticeable improvement, an injection or a referral for surgery may be where the conversation starts.
Frequently Asked Questions
What kind of doctor should I see for de Quervain’s tenosynovitis? A hand surgeon is the appropriate specialist for this condition. A hand surgeon can distinguish de Quervain’s from arthritis at the base of the thumb, which presents similarly but requires different treatment. Dr. Fort is a fellowship-trained orthopedic hand surgeon (FAAOS) and provides both nonsurgical and surgical care for de Quervain’s at Fort Orthopedic Hand Center in Miami.
Does insurance cover de Quervain’s release surgery? Many private insurance plans cover de Quervain’s release when conservative treatment, such as splinting or injection, has been attempted first. Coverage depends on your specific plan. Contact Fort Orthopedic Hand Center to discuss your insurance and whether you might expect coverage.
What is the fastest way to treat de Quervain’s tenosynovitis? A corticosteroid injection is typically the fastest nonsurgical treatment. It often provides significant relief within one to two weeks. When combined with splinting and temporary rest from the aggravating activity, most patients see improvement without surgery. If symptoms persist after one or two injections, surgical release is highly effective.
What is a red flag for de Quervain’s tenosynovitis? Seek care promptly if you experience numbness or tingling in the thumb, sudden worsening of pain at rest, or swelling that extends up the forearm. These may indicate a more complex condition or nerve involvement beyond de Quervain’s.
Does de Quervain’s ever go away on its own? In mild cases, especially those triggered by a temporary activity like caring for a newborn, symptoms sometimes improve once the repetitive motion stops. Most cases, however, require some form of treatment to fully resolve. Without treatment, the tendon sheath can remain thickened, and pain during thumb use tends to persist.
What should I expect for recovery after de Quervain’s release surgery? Most patients regain full thumb function within four to six weeks of surgery. The wrist is splinted for a short period postoperatively, after which physical therapy helps restore strength and range of motion. Surgical patients report high satisfaction rates, and the condition rarely recurs after release surgery.
When Thumb Pain is Affecting Your Daily Life
Most de Quervain’s cases improve with nonsurgical treatment, especially when the condition is caught early. The longer the tendon sheath stays irritated and inflamed, the longer recovery tends to take, which is why early diagnosis and treatment make such a difference for our patients.
Your consultation with Dr. Fort will start with a physical exam and a clear diagnosis so you know exactly what you’re dealing with and what the right next step is, whether that’s a splint, an injection, or something else.
