How to unlock trigger finger?
Our hands are an incredible gift, enabling us to perform countless tasks with precision and dexterity. However, when the tendon sheath becomes narrowed or thickened, it restricts the tendon’s movement, leading to a catching sensation during finger movement.
Trigger finger, also known as stenosing tenosynovitis, affects the flexor tendons in the hand, causing discomfort and limited mobility. In this blog post, we will explore the causes, prevention, and available treatment options for trigger finger, shedding light on this often-overlooked condition.
Dupuytren’s Contracture vs Trigger Finger
Trigger finger occurs when the flexor tendons, responsible for the movement of your fingers, become inflamed or irritated. These tendons slide smoothly through a series of pulleys known as the tendon sheaths. However, when the tendon sheath becomes narrowed or thickened, it restricts the tendon’s movement, leading to a catching sensation during finger movement.
Dupuytren’s forms knots under the skin of the palm. As these knots form, they create a cord that pulls the fingers into a bent position.
The exact cause of trigger finger is not always clear. However, certain factors can increase the risk of developing this condition. These include-
*Repetitive Hand Movements- Engaging in repetitive hand motions, especially gripping or grasping activities, can strain the flexor tendons, leading to this condition.
*Medical Conditions- Conditions such as rheumatoid arthritis, diabetes, and hypothyroidism are associated with an increased risk of trigger finger.
*Gender and Age- Trigger finger is more prevalent in women than in men, and it often affects individuals between the ages of 40 and 60.
Is trigger finger a form of arthritis?
In these cases, the inflammation associated with arthritis can affect the tendons and contribute to the development of trigger finger.
De Quervain’s Tenosynovitis
The location of pain differentiates between trigger finger and De Quervain’s tenosynovitis. Trigger finger affects the tendons of the hand, while pain or tenderness arising at the base of your thumb is called de Quervain’s tenosynovitis.
Treatment
Treatment options may vary depending on the severity of the condition. Here are some common approaches–
*Shockwave therapy– It has emerged as a promising treatment option for individuals suffering from trigger finger, a condition characterized by the painful locking of a finger joint. This non-invasive procedure involves the delivery of high-intensity sound waves to the affected area, stimulating the body’s natural healing response.
*Chiropractic- Chiropractors primarily focus on diagnosing and treating musculoskeletal conditions, including joint dysfunctions. While chiropractic care may offer some benefits in terms of pain management and improving joint function.
*Osteopathy- Osteopathic practitioners aim to improve overall health and well-being by focusing on the musculoskeletal system.
*Physiotherapy- also known as physical therapy, can play a role in the conservative management of trigger finger. Our Physiotherapists may use various techniques, such as exercises, stretches, manual therapy, and modalities like heat therapy, to alleviate pain, improve finger mobility, and restore normal hand function.
*Massage Therapy- Massage therapy involves manual manipulation of soft tissues to promote relaxation, relieve muscle tension, and enhance circulation.
*Rest and Splinting- Resting the affected hand and avoiding repetitive movements can provide relief. Wearing a splint to immobilize the finger can also promote healing.
*Hand Exercises- Gentle stretching and strengthening exercises prescribed by a physical or occupational therapist can help improve the flexibility and range of motion of the affected finger.

*Hand Therapy- Hand therapy involves various techniques, such as massage and exercises to improve the function of the affected finger. It can be helpful in combination with other treatments.
Prevention
While trigger finger cannot always be prevented, taking certain measures may help reduce the risk of its occurrence. These include-
*Taking Regular Breaks- If your work involves repetitive hand movements, make it a habit to take regular breaks to rest your hands and fingers.
*Modifying Hand Movements- When engaging in activities that strain the fingers, try to modify your technique or use tools that minimize stress on the tendons.
*Maintaining a Healthy Lifestyle- Managing underlying conditions like diabetes, arthritis, and hypothyroidism can lower the risk of developing trigger finger.
*Use Proper Tools and Techniques- When engaging in activities that involve repetitive hand movements, use tools and equipment that are designed to reduce strain. Additionally, learn and implement proper techniques to minimize stress on the tendons.
*Avoid Repetitive Gripping– Try to vary your hand movements and avoid prolonged repetitive gripping or grasping actions. If possible, use different fingers or alternate hands for tasks that involve gripping.
*Ergonomic Workstation- Ensure that your workstation is set up ergonomically. Use a supportive chair, maintain proper posture, and position your keyboard and mouse to minimize strain on your hands and fingers.
