Sclerosing tenosynovitis, also called De Quervain's tenosynovitis, is a condition where the tendon sheath on the thumb side of the wrist becomes thickened and inflamed.

It's often caused by repetitive thumb or wrist motion, such as gripping or twisting activities.

Symptoms include pain and swelling on the thumb side of the wrist, worsened by thumb or wrist movement.

Diagnosis is typically based on a physical exam, including a specific test where the thumb is tucked into the palm and the wrist bent.

Yes, it's common in caregivers of infants due to repetitive lifting motions, sometimes called 'mommy thumb.'

Treatment often includes splinting, activity modification, anti-inflammatory measures, and sometimes steroid injections.

Surgery may be considered if conservative treatments don't provide adequate relief.

Surgery typically involves releasing the tight tendon sheath to relieve pressure on the tendons.

Recovery often takes a few weeks, with gradual return to full activity.

Yes, a splint that supports the thumb and wrist can help rest the affected tendons.

Yes, corticosteroid injections can be quite effective for reducing inflammation and pain.

Yes, pain along the thumb side of the wrist is a hallmark symptom, especially with certain movements.

Yes, pain and swelling can reduce grip and pinch strength.

Therapy may help with symptom management and guided return to activity.

Yes, it can occur in one or both wrists, especially with bilateral repetitive activities.

Yes, it's more commonly diagnosed in women, particularly new mothers and middle-aged individuals.

Repetitive wrist and thumb movements, including certain typing or texting habits, can contribute to symptoms.

Yes, this is the classic test used to help diagnose sclerosing tenosynovitis by reproducing thumb-side wrist pain.

Yes, hormonal changes during pregnancy may contribute to increased risk.

Yes, avoiding or modifying activities that worsen symptoms is generally recommended.

Mild cases may improve with rest, though many benefit from splinting or other treatment for full relief.

Yes, icing the affected area can help reduce pain and inflammation.

Yes, repetitive thumb texting motions can aggravate symptoms of sclerosing tenosynovitis.

Some people may benefit from a second injection if symptoms persist, though this varies by individual.

Yes, surgery generally provides good relief for cases that haven't responded to conservative treatment.

Recurrence is possible, especially if repetitive strain activities continue without modification.

Swelling is common but may vary in visibility depending on severity.

Using proper lifting techniques and varying hand positions when caring for an infant may help reduce risk.

Your doctor will guide how much to wear the splint, often including at least during aggravating activities.

Gentle massage may provide some relief, though it should be guided by a therapist or doctor.

Both involve tendon sheath issues, though they affect different structures and have somewhat different presentations.

Yes, therapy can help you adapt activities to reduce strain on the affected tendons.

Depending on job demands, some modification or brief time off may be helpful during flare-ups.

A night splint may help some people manage symptoms, especially during flare-ups.

Yes, avoiding heavy or repetitive gripping is recommended during treatment.

There isn't a strong known genetic link; it's primarily related to repetitive use and anatomy.

It's less common without repetitive strain, though anatomical factors can play a role in some cases.

Many people regain good grip strength with appropriate treatment and rest.

Yes, symptoms can overlap with thumb arthritis, so an accurate diagnosis is important.

Yes, thumb spica splints, which immobilize the thumb and wrist, are commonly used.

Yes, a gradual return to normal activity helps reduce the risk of symptoms returning.

Yes, sports involving repetitive wrist and thumb motion can contribute to this condition.

Gentle stretching, as guided by a therapist, may help with symptom management.

Some thickening or swelling may be palpable, though a distinct lump isn't always present.

Yes, follow-up is important if symptoms persist despite initial treatment.

Supportive gloves or wraps may help some people during specific activities, though a proper splint is often more effective.

It can occur at various ages, often related to activity level and repetitive use rather than age alone.

Yes, thumb pain can make fine motor tasks involving pinch grip more difficult.

Coverage varies by plan, so checking with your insurance provider is recommended.

Yes, hand therapists can help ensure proper splint fit and provide guidance throughout treatment.

See a doctor if you have persistent thumb-side wrist pain that limits your daily activities.
