A painful condition affecting the tendons on the thumb side of the wrist.
It is inflammation of two tendons that control movement of the thumb and their tendon sheath. This results in pain at the outside of the wrist.
Repetitive hand or wrist movements can make the condition worse.
Pain will typically increase when patient try to grip or during rotation of wrist.
Pathophysiology
In De Quervain syndrome involves non inflammatory thickening of the tendons and synovial sheaths.
There are two tendons present first is extensor pollicis brevis and the second is abductor pollicis longus.
These two muscles run side by side and function to bring the thumb away from the hand. The thumb outwards radially, and abductor pollicis longus brings the thumb forward away from the palm.
De Quervain tendinopathy affects the tendon of these muscles as they pass from the forearm into hand via a fibro-osseous tunnel which is first dorsal compartment.
The cause of De Quervain syndrome is not established.
The most common cause of De Quervain tendinopathy is chronic overuse of the wrist. Repetitive movement day after day cause irritation and pain. One common movement that causes it is lifting a child into a car seat. Another is lifting a heavy grocery bags by include a direct injury to the wrist or inflammatory arthritis.
De quervain syndrome is diagnosed clinically based on history and physical examination, though diagnostic imaging such as X-ray to rule out fracture, arthritis or other causes.
There is special test present for the De Quervain syndrome which called Finkelstein’s test. It’s a physical examination test. To perform the test, the examiner grasps and ulnar deviates the hand when the person has their thumb held within their fist. If sharp pain occurs along the distal radius (top of forearm, about an inch below the wrist.)
De Quervain syndrome is likely.
While a positive Finkelstein’s test is often considered pathogenesis for De Quervain syndrome.
Neurological test
This test is in supine lying. The first step is shoulder depression, followed by elbow extension, then medial rotation of the whole arm, and finally adding the last component which is wrist, finger and thumb flexion. If there is pain or tingling sensation or numbness at any stage during the movement at any step, confirms the muscle involvement.
This is performed by lightly tapping the nerve over the nerve to elicit a sensation of tingling or pins and needles in the distribution of the nerve.
Be aware of patient's thumb position while performing this maneuver.
The goal in treating De quervain tendinitis is to relieve the pain caused by irritation and swelling.
Surgical treatment
Surgical is rare and is usually for those when non-surgical treatment has failed and the patient experiences persistent inflammation affecting his or her function. The goal of surgery is to open the dorsal compartment covering to make more room for the irritated tendons. The openings allow pressure relief of the tendons, to ultimately restore free tendon gliding.
Physiotherapy treatment
Ice/Heat Packs
Heat can help relax and loosen tight musculature, and ice can be used to help relieve inflammation of the extensor sheath.
Massage
Deep tissue massage at the thenar eminence can help relax tight musculature that causes pain.
Stretching
Stretching the thenar eminence muscles into thumb extension and abduction can relax and lengthen this tight musculature that causes pain.
Decreasing Swelling
To decrease swelling you can use:
Improving Range of Motion
Stretching as explained above can be used to improve range of motion. Ice/Heat packs can relax tight musculature so that you can attain a bigger range of motion.
Increasing Strength
Any of above stretching and strengthening exercises can be done as a home exercise program (HEP). Patients can also use ice and heat packs at home. After education, patients can perform self-massage techniques at home, and if chosen as the preferred intervention.
Expert Treatment
There are various advanced techniques available these days which gives a better and complete recovery from the ailment. As compared to with the conventional and traditional treatments which are available with most of the therapist, these new techniques give the best results in the long run.
In these treatments, we work on the muscles and fascia. Basically, whenever there is pain, inflammation, injury, postural imbalance, due to overstretching or over-contraction etc. result in taught band formation known as trigger points. These points are basically reducing the length of the muscle which impairs the joint function and ROM. Every muscle has a trigger point patter. We are working on the faulty biomechanics by releasing these trigger points. Releasing the trigger points results restoring the normal biomechanics, with normal ROM and joint function.
These techniques include:
