Using Thumb Splints to Treat De Quervain’s - Updated 2024

When treating de Quervain’s Tenosynovitis, patients often experience a swollen thumb and pain on the radial side of the wrist. This discomfort typically worsens and can extend up the thumb or forearm during activities involving thumb abduction or flexion. While overuse or repetitive stress is the common cause, in some cases, the condition arises without a clear reason.

Recognizing Symptoms of de Quervain’s

• Radial-sided wrist pain with or without inflammation at the base of the thumb
• Pain with thumb abduction or flexion
• Inflammation over the thumb side of the wrist
• A snapping or catching sensation when moving the thumb
• Numbness of the back of the thumb that may spread to the index finger

Treatment of de Quervain’s

De Quervain’s pain has tendinopathic origins, making physical and occupational therapy effective. Treatments often include nonsteroidal agents, cryotherapy, and topical corticosteroids with ultrasound and iontophoresis are often helpful in managing the symptoms.

Splints and Braces for de Quervain's

Splinting remains a first-line conservative treatment. Depending on the severity and longevity of the symptoms, splinting choices may be soft flexible splints for mild or occasional symptoms, moderately restrictive splints for more severe and persistent symptoms and firm supports that restrict motion for more severe, long-standing pain.   

The 3pp Ez FIT Thumb Spica Splint stands out as an effective solution. Its full-length aluminum stay can be custom contoured to hold the thumb and wrist in optimal positions, while the open palm design ensures functionality and patient compliance. It’s lightweight and breathable, providing all-day comfort

Follow-up care is crucial. If symptoms persist despite full-time splint use, consider referring the patient for further treatment or surgical intervention.
