Have you ever experienced a sharp pain on the thumb side of your wrist that makes even the simplest tasks, like opening a jar or typing on your keyboard, feel impossible? Could it be De Quervain's tenosynovitis causing this discomfort?
De Quervain's tenosynovitis is a condition that might sound unfamiliar, yet it's surprisingly common, especially amongst individuals who perform repetitive hand and wrist motions. Named after the Swiss surgeon Fritz de Quervain, who described it in 1895, this painful condition arises when the tendons around the base of the thumb become irritated or compressed.
Whether you're an avid smartphone user, a new parent often lifting a baby, or someone involved in a manual profession, understanding De Quervain's tenosynovitis is crucial for both prevention and management.
What is De Quervain's tenosynovitis?
The abductor pollicis longus (APL) and extensor pollicis brevis (EPB) tendons are responsible for bringing the thumb in an outward direction.
Thickening of the sheath from acute or long-term repetitive trauma restricts normal gliding and sliding of the tendons. This causes inflammation and further thickening within the sheath and not the tendons themselves.
Individuals who perform repetitive pinching tasks and grasping tasks are most susceptible to this condition.
Examples include:
- Barbers who use scissors regularly.
- Gardeners with shears.
- Mothers with newborns often suffer from this condition from the repetitive motion of holding the infant with the thumb in a prolonged, extended position.
Common causes of De Quervain's tenosynovitis
- Repetitive motions involving the thumb and wrist.
- Injuries to the wrist or thumb.
- Hormonal changes, especially during pregnancy or breastfeeding.
- Wrist anatomy or genetics.
Common symptoms of De Quervain's tenosynovitis
- Pain near the base of the thumb.
- Swelling in the wrist on the thumb side.
- Difficulty moving the thumb and wrist, especially when grasping or pinching.
- A "sticking" or "stop-and-go" sensation when moving the thumb.
- Pain that may radiate up the forearm.
With appropriate treatment, most people with De Quervain's tenosynovitis experience significant improvement in their symptoms. Early intervention and adherence to treatment plans can lead to a faster recovery.
How to diagnose De Quervain's tenosynovitis
Your health practitioner will first take the subjective history of your condition. A physical examination is followed by this to confirm the diagnosis. Should this not be clear enough, an ultrasound scan can be organised with a 95% specificity and 85% sensitivity in diagnosing De Quervain's tenosynovitis.
The percentages mean ultrasound scans are effective in identifying De Quervain's tenosynovitis. Further scans, such as MRI, are even more effective in diagnosing; however, they are often not required.
Treatment pathways for De Quervain's tenosynovitis
There are two of the most common pathways for De Quervain's tenosynovitis. These include conservative and surgical management.
Conservative management involves wearing a splint to allow the thumb and wrist to rest. A gentle stretch is often prescribed, and strengthening once it is tolerable. Other factors, such as changes to ergonomics, are optimised on a case-by-case basis.
If this does not settle the symptoms enough, a cortisone injection coupled with splinting is even more effective than splinting alone or injection alone over 6 months. The splinting timeframe is often discussed with the individual and would involve wearing it for 4 to 6 weeks first.
Should conservative treatment fail, surgical management is the next step. The surgery is a simple release of the thickened retinaculum tissue that covers the sheath of the tendons.
Generally, this has a high success rate given the individual stays compliant with the post-op rehabilitation.
How long does it take to recover from De Quervain's tenosynovitis?
-
Non-surgical treatment
- If treatment begins early, symptoms often improve within 4 to 6 weeks.
- This typically involves rest, splinting, and sometimes corticosteroid injections.
-
Surgical treatment
- Recovery after surgery can take longer.
- It may take 6 to 12 weeks for complete healing.
- Full recovery, including the return of full strength and function, can take several months.
Key factors influencing recovery time for De Quervain's tenosynovitis
- Severity of the condition: Milder cases tend to resolve more quickly.
- Early intervention: Starting treatment early can significantly shorten recovery time.
- Individual response to treatment: People heal at different rates.
- Treatment adherence: Following your doctor's instructions, such as wearing a splint and avoiding aggravating activities, is crucial.
It's important to consult with a healthcare professional for an accurate diagnosis and personalised treatment plan.
