• The main symptom is pain felt over the thumb side of the wrist and can spread upwards to the forearm. The pain tends to develop slowly over time and is typically increased with thumb movements involving grasping or pinching, or on wrist rotation.
• Swelling over the thumb side of the wrist. Sometimes a fluid-filled cyst may be seen
• Difficulty moving the thumb and wrist
• A catching or snapping sensation in the thumb when moving it

What are the Risk Factors for De Quervain’s Tenosynovitis?

De Quervain’s Tenosynovitis can be diagnosed by your doctor after a detailed history and physical examination of the wrist and affected thumb. Usually, no investigations or X-rays are required.

The treatment for De Quervain’s Tenosynovitis depends on the severity and include:

• Avoidance of the causative activity
• Painkillers such as paracetamol and nonsteroidal anti-inflammatory drugs (NSAIDs)
• Gentle exercises to strengthen the muscles, relieve the pain and reduce irritation to the tendon
• Wearing a splint to immobilize the wrist and thumb
• Extracorporeal Shockwave Therapy (ESWT). This is a painless and non-invasive procedure which causes improvement in blood circulation and a tissue-repairing effect on the inflamed tendons
• Corticosteroid (H&L) injection. This is injected into and around the tendon sheath, and reduces the inflammation. The effect may be temporary, usually around 3 months, but may sometimes last a year or longer. More than one injection may be necessary.
• If all else fails, surgery can be considered. The procedure involves releasing the tendon to allow it to glide freely, and is usually performed under local anaesthesia.
