What Is De Quervain’s Tenosynovitis?

De Quervain’s tenosynovitis is a painful condition affecting the tendons on the thumb side of the wrist. It occurs when the tendons around the base of the thumb, specifically the extensor pollicis brevis and abductor pollicis longus tendons, become inflamed and thickened.

This inflammation can cause pain and tenderness along the thumb side of the wrist, making it difficult to move the thumb and wrist without discomfort.

Common Causes of De Quervain’s Tenosynovitis

The primary cause of De Quervain’s tenosynovitis is repetitive strain on the wrist and thumb. Activities that involve repeated or forceful movements of the wrist and thumb can irritate the tendons and their surrounding sheath, leading to inflammation. Common culprits include:

  • Caregiving for infants: Lifting and holding a baby, often referred to as “mommy’s thumb,” is a frequent cause due to the repetitive motion of lifting and supporting the baby’s head.
  • Sports and hobbies: Activities like golf, tennis, fishing, and even gardening can contribute to the condition if they involve repetitive wrist and thumb movements.
  • Occupational tasks: Jobs that require repetitive hand or wrist motions, such as those involving assembly lines, typing, or using hand tools, can increase the risk.
  • Direct injury: A direct blow to the wrist or a sudden, forceful twist can also trigger inflammation.
  • Hormonal factors: Hormonal changes, such as those occurring during pregnancy or menopause, may also play a role in the development of De Quervain’s tenosynovitis.

Treatment Options for De Quervain’s Tenosynovitis

Treatment for De Quervain’s tenosynovitis typically begins with conservative, non-surgical approaches aimed at reducing inflammation and pain. The goal is to rest the affected tendons and allow them to heal.

Conservative Treatments:

  • Activity Modification: Avoiding the activities that aggravate the condition is crucial. This may involve changing how you perform certain tasks or taking breaks to rest your wrist and thumb.
  • Splinting: Wearing a splint or brace that immobilizes the thumb, and wrist can help reduce movement and provide support, allowing the tendons to rest.
  • Nonsteroidal Anti-inflammatory Drugs (NSAIDs): Over-the-counter or prescription NSAIDs, such as ibuprofen or naproxen, can help reduce pain and inflammation.
  • Corticosteroid Injections: Injections of corticosteroids into the tendon sheath can effectively reduce inflammation and pain, often providing significant relief. This is a common next step if activity modification and splinting are not sufficient. The most important aspect of the efficacy of steroid injection is following physiotherapy exercises after the injection.
  • Physiotherapy: A physical therapist can provide guidance on exercises to stretch and strengthen the wrist and thumb, as well as techniques to improve posture and reduce strain during daily activities.

Surgical Treatment:

If conservative treatments do not relieve symptoms, surgery may be recommended. The surgical procedure for De Quervain’s tenosynovitis is typically an outpatient procedure that involves releasing the sheath that surrounds the inflamed tendons.

This creates more space for the tendons to glide freely, reducing friction and pain. Surgical intervention has a high success rate, with many studies reporting good outcomes in over 90% of cases. The decision to proceed with surgery is usually made based on the severity of symptoms and the failure of conservative measures. Recovery time after surgery is generally minimal.

Diagnosis and Beyond

Diagnosis of De Quervain’s tenosynovitis is often made through a physical examination and a review of your medical history. A common diagnostic test is Finkelstein’s test, which involves bending your thumb across your palm and then bending your fingers down over your thumb, followed by bending your wrist towards your little finger. If this movement causes pain on the thumb side of your wrist, it may indicate De Quervain’s tenosynovitis.

While current treatments are generally effective, ongoing research continues to explore long-term outcomes of non-surgical treatments and optimal timing for surgical intervention. Additionally, research into more targeted rehabilitation protocols is an area of ongoing investigation.

It’s important to consult with a healthcare professional for an accurate diagnosis and appropriate treatment plan for De Quervain’s tenosynovitis.
