De Quervain’s Tenosynovitis
Author: Jerry Song
De Quervain’s tenosynovitis, also known as “washerwoman’s sprain” or “gamer’s thumb,” is an inflammatory condition involving the extensor pollicis brevis (EPB) and abductor pollicis longus (APL) tendons. These tendons run along the thumb side of the wrist and are responsible for thumb extension and abduction. Inflammation of the synovial sheath that surrounds these tendons leads to pain, swelling, and restricted movement. As a result, patients often experience difficulty with activities that involve grasping, pinching, or thumb movements.
The hallmark symptom of De Quervain’s tenosynovitis is pain and tenderness over the radial side of the wrist, which can radiate up the forearm or down into the thumb. The Finkelstein test is a common diagnostic manoeuver in which the patient bends their thumb into their palm and wraps their fingers over it, followed by ulnar deviation (moving the wrist toward the pinky side). A positive test, characterised by sharp pain, is indicative of De Quervain’s tenosynovitis.
Causes of De Quervain’s Tenosynovitis
De Quervain’s tenosynovitis is primarily caused by overuse or repetitive strain of the tendons involved in thumb movement. Specific causes include:
- Repetitive Hand and Wrist Movements:Activities that involve repetitive motions of the thumb and wrist, such as lifting, grasping, and pinching, are a leading cause of De Quervain’s tenosynovitis. These activities place strain on the APL and EPB tendons, leading to inflammation and irritation. Common repetitive tasks include typing, texting, gardening, and lifting infants.
- Direct Trauma or Injury:Acute trauma to the wrist or thumb area, such as a direct blow or excessive strain, can trigger inflammation in the tendons and synovial sheath, leading to De Quervain’s tenosynovitis.
- Chronic Overload:Repeated overloading of the tendons over time, even without obvious injury, can lead to microtrauma in the tendons, resulting in inflammation, swelling, and thickening of the tendon sheath.
- Inflammatory Conditions:Systemic inflammatory diseases, such as rheumatoid arthritis, may contribute to the development of De Quervain’s tenosynovitis due to underlying chronic inflammation in the joints and tendons.
Demographics Most Likely to Suffer from De Quervain’s Tenosynovitis
While De Quervain’s tenosynovitis can affect individuals of all ages and backgrounds, certain demographics are at higher risk of developing the condition:
- Women:De Quervain’s tenosynovitis is more common in women than men, with some studies suggesting a female-to-male ratio of 4:1. This may be due to anatomical differences in tendon and joint structures, as well as the increased likelihood of women engaging in repetitive tasks such as child-rearing, household chores, or manual labor that involves hand and wrist movements.
- Postpartum Women:New mothers are particularly susceptible to De Quervain’s tenosynovitis due to the repetitive lifting and holding of infants. This condition is often referred to as “mommy’s thumb” because the motion of lifting a baby from a crib, car seat, or carrier places strain on the thumb and wrist tendons.
- Manual Labourers and Office Workers:Individuals whose occupations involve repetitive wrist and thumb movements, such as typists, assembly line workers, carpenters, and hairdressers, are at a higher risk of developing De Quervain’s tenosynovitis due to repetitive strain and overuse.
- Smartphone and Video Game Users:The rise of smartphone usage and video gaming has led to an increase in cases of De Quervain’s tenosynovitis, particularly among younger demographics. Prolonged texting, scrolling, and gaming require constant thumb movement, which can lead to inflammation of the thumb tendons over time.
How Manual Therapy Can Help Treat and Manage De Quervain’s Tenosynovitis
Manual therapy is a non-invasive approach to managing musculoskeletal conditions, including De Quervain’s tenosynovitis. It involves various hands-on techniques aimed at reducing pain, improving mobility, and addressing underlying muscular imbalances. Manual therapy has shown promise in reducing symptoms and facilitating recovery in patients with this condition.
- Soft Tissue Mobilisation and Massage
Soft tissue mobilisation and massage techniques target the muscles, tendons, and fascia surrounding the wrist and thumb. This approach helps reduce tension, improve blood flow, and promote healing in the affected tendons. Soft tissue techniques can alleviate pain and prevent the progression of inflammation by addressing tightness in the muscles around the wrist and hand.
- Joint Mobilisation
Joint mobilisation techniques can help improve the range of motion in the wrist and thumb joints by gently moving the joints through their natural range. This technique is particularly beneficial for individuals experiencing stiffness or restricted movement due to inflammation and swelling.
- Dry Needling
Dry needling is a manual therapy technique in which fine needles are inserted into specific trigger points or tight bands of muscle to release tension and reduce pain. In the context of De Quervain’s tenosynovitis, dry needling can be used to target the muscles and tendons involved in thumb and wrist movement, particularly the APL and EPB tendons.
Dry needling works by stimulating blood flow to the area, promoting the release of tight muscle fibers, and reducing local inflammation. This helps alleviate pain and allows the affected tendons to heal more effectively. When combined with other manual therapy techniques, dry needling can help accelerate recovery and improve overall function in patients with De Quervain’s tenosynovitis.
- Myofascial Cupping
Myofascial cupping is a technique in which suction cups are placed on the skin to create negative pressure, lifting the skin and underlying fascia. This technique improves blood circulation, reduces fascial adhesions, and promotes tissue healing. In cases of De Quervain’s tenosynovitis, myofascial cupping can be applied to the forearm, wrist, and thumb areas to relieve tension and reduce inflammation.
Cupping helps improve tissue mobility by releasing tight fascia and muscles, allowing for better tendon glide and reduced pain. It can also be used in conjunction with stretching and strengthening exercises to improve range of motion and restore function to the affected area.
- Stretching and Strengthening Exercises
Manual therapy often includes the incorporation of therapeutic exercises designed to stretch tight muscles and strengthen weak ones. Specific exercises for De Quervain’s tenosynovitis may include wrist stretches, thumb abduction and extension exercises, and forearm strengthening movements. These exercises help improve flexibility, restore tendon function, and prevent recurrence of the condition.
Benefits of Manual Therapy in Managing De Quervain’s Tenosynovitis
Manual therapy offers several benefits in the management of De Quervain’s tenosynovitis, including:
- Pain Relief:Manual therapy techniques, including soft tissue mobilisation, dry needling, and myofascial cupping, help alleviate pain by reducing inflammation and releasing tight muscles.
- Improved Mobility:By addressing joint stiffness and tendon adhesions, manual therapy helps improve range of motion in the wrist and thumb, allowing patients to perform daily activities with less discomfort.
- Increased Blood Flow:Techniques such as massage, dry needling, and cupping promote circulation to the affected area, which enhances tissue healing and reduces recovery time.
- Reduced Inflammation:Manual therapy helps reduce swelling and inflammation in the tendons and surrounding tissues, which is crucial for managing the symptoms of De Quervain’s tenosynovitis.
- Prevention of Recurrence:By incorporating strengthening exercises and ergonomic advice, manual therapy can help prevent the recurrence of De Quervain’s tenosynovitis by addressing the root causes of tendon overuse and imbalance.
