What is De Quervain's tenosynovitis?
De Quervain's tenosynovitis is inflammation of tendons on the side of the wrist at the base of the thumb. These tendons include the extensor pollicis brevis and the abductor pollicis longus tendons. De Quervain's tenosynovitis can be brought on by simple strain injury to the extensor pollicus longus tendon. Typical causes include stresses such as lifting young children into car seats, lifting heavy grocery bags by the loops, and lifting gardening pots up and into place.
What are symptoms of De Quervain's tenosynovitis?
De Quervain's tenosynovitis causes pain and tenderness at the side of the wrist beneath the base of the thumb. Sometimes there is slight swelling and redness in the area.
How is De Quervain's tenosynovitis diagnosed?
De Quervain's tenosynovitis is diagnosed based on the typical appearance, location of pain, and tenderness of the affected wrist. De Quervain's tenosynovitis is usually associated with pain when the thumb is folded across the palm and the fingers are flexed over the thumb as the hand is pulled away from the involved wrist area. (This is referred to as the Finkelstein maneuver.)
How is De Quervain's tenosynovitis treated?
Treatments for De Quervain's tenosynovitis includes any combination of rest, splinting, ice, antiinflammation medication, and/or cortisone injection. Cortisone injection is extremely effective and is generally the optimal treatment. Normal activity may be resumed within three weeks after an injection. Surgery is only rarely necessary and usually reserved for persisting inflammation after failure of at least one cortisone injection.
What is the outlook (prognosis) with De Quervain's tenosynovitis?
Excellent. The patient can generally return to full function after the inflammation quiets down with treatment. Sometimes bracing is used during future activities that involve repetitive wrist motion.
Nape aku paste pasal "De Quervain's tenosynovitis"(DQT) kt atas nih?..mm.. on 9.11.09 aku ada appointment ngan doc kt unit Orthopedik, Hosp Serdang. n doc said this is my disease... aku dh mengalami penyakit ni dh 3 bulan lepas. sakit woo.. urut pun dh 3 kali tp takde apa2 yg berkesan kt my wrist.. lastly aku refer hospital serdang.. x-ray my wrist, doc kata ok..takde masalah cuma urat wrist aku yg bermasalah.. inilah dia yg dikatakan DQT..
solution yg doc kasi.. 1.FISIOTERAPI-ni yg doc shorekan utk masa terdekat, so next appointment on 24.11.09 aku kena gi kt unit Fisioterapi plak..then on 14.12.09 going back to Orthopedik..tgok samada berkesan ke tak 2. SIMEN- simen jek tgn, tp tgn takleh gunala..cmne nk jaga my baby..huhu..lagipun doc kata, keberkesanannya just 50% utk pulih.. 3. INJECTION/STEROID - yg ni bole buat on d dot masa haritu, tp kesannya takleh bagi susu kt Ira la plak.. sebulan tuh..huhu..ira nk minum apa.. 4. OPERATION -ini yg doc shorekan cuma kalo nk buat operation nih, lambat lagilah..kena dtg 2nd appointment dulu then baru leh bg date buat operation..this is just minor operation jek..kasi bius kt tgn,t hen operate dlm 20 minutes..means aku leh tgok cmne dorg bedah my wrist..keberkesanannya 90%..so hope 2nd appmt nt aku dpt date utk operate.. rasa better yg ni kot.. tp apa2 pun kita buat fisioterapi dulu, manatau kot2 berkesan.. so cuba korg tgok gmbr tgn aku kt bawah ni..apa perbezaannya?..cuba cari k..
ni tgn kananku yg kena DQT. nmpk tak mcm tulangku terkeluar sket.. sebelah kiri lurus jek.
A Patient's Guide to de Quervain's Tenosynovitis
 | Introductionde Quervain's tenosynovitis is a condition that causes pain on the inside of the wrist and forearm just above the thumb. It is a common problem affecting the wrist and is usually easy to diagnose. |
.What part of my thumb and wrist is causing problems?
de Quervain's tenosynovitis affects two thumb tendons. These tendons are called the abductor pollicis longus (APL) and the extensor pollicis brevis (EPB).
Tendons connect muscle to bone. Muscles pull on tendons for movement. The muscles connected to the APL and EPB tendons are on the back of the forearm. The muscles angle toward the thumb.
On their way to the thumb, the APL and EPB tendons travel side by side along the inside edge of the wrist. They pass through a tunnel near the end of the radius bone of the forearm. The tunnel helps hold the tendons in place, like the guide on a fishing pole.
This tunnel is lined with a slippery coating called tenosynovium. The tenosynovium is a slippery covering that allows the two tendons to glide easily back and forth as they move the thumb. Inflammation of the tenosynovium and tendon is called tenosynovitis. In de Quervain's tenosynovitis, the inflammation constricts the movement of the tendons within the tunnel.
Causes
How did this condition develop?
Repeatedly performing hand and thumb motions such as grasping, pinching, squeezing, or wringing may lead to the inflammation of tenosynovitis. This inflammation can lead to swelling, which hampers the smooth gliding action of the tendons within the tunnel. Arthritic diseases that affect the whole body, such as rheumatoid arthritis, can also cause tenosynovitis in the thumb. In other cases, scar tissue from an injury can make it difficult for the tendons to slide easily through the tunnel.
Symptoms
What problems does this condition cause?
At first, the only sign of trouble may be soreness on the thumb side of the forearm, near the wrist. If the problem isn't treated, pain may spread up the forearm or further down into the wrist and thumb.
As the friction increases, the two tendons may actually begin to squeak as they move through the constricted tunnel. This noise is called crepitus. If the condition is especially bad, there may be swelling along the tunnel near the edge of the wrist. Grasping objects with the thumb and hand may become increasingly painful.
Diagnosis
What tests will my doctor want to do?
Doctors usually diagnose de Quervain's tenosynovitis easily through a physical examination. Most of the time no fancy tests are required. The major problem can be distinguishing de Quervain's tenosynovitis from intersection syndrome, which is a very similar condition.
Document Link: A Patient's Guide to Intersection Syndrome
Careful attention must be paid to where the pain is located--over de Quervain's tunnel near the end of the radius bone, or over the intersection point on the wrist. The intersection point is about three inches up the forearm.
The Finklestein test is one of the best ways to make the diagnosis. You can do this test yourself. Bend your thumb into the palm and grasp the thumb with your fingers making a fist with the thumb inside. Now bend your wrist away from your thumb in a side to side motion. If you feel pain over the tendons to the thumb, your problem may be de Quervain's tenosynovitis.
Treatment
How can I make the pain go away?
Conservative Treatment
If at all possible, you must change or stop all activities that cause your symptoms. Take frequent breaks when doing repeated hand and thumb actions. Avoid repetitive hand motions, such as heavy grasping, wringing, or turning and twisting movements of the wrist. Keep the wrist in a neutral alignment. In other words, keep it in a straight line with your arm, without bending it forward or backward.
Your doctor may want you to wear a special forearm and thumb splint called a thumb-spica splint. This splint keeps the wrist and lower joints of the thumb from moving. The splint allows the APL and EPB tendons to rest, giving them a chance to begin to heal.
Anti-inflammatory medications may also help control the swelling of the tenosynovium and ease symptoms. These medications include common over-the-counter medications such as ibuprofen and aspirin.
If these simple measures fail to control your symptoms, your doctor may suggest an injection of cortisone into the irritated tunnel. Cortisone reduces the swelling of the tenosynovium and may temporarily relieve your symptoms. Cortisone injections will usually control the inflammation in the early stages of the problem.
Your doctor may have you work with a physical or occupational therapist. The main focus of therapy is to reduce or eliminate the cause of irritation of the thumb tendons. Your therapist may check your workstation and the way you do your work tasks. Suggestions may be given about the use of healthy body alignment and wrist positions, helpful exercises, and tips on how to prevent future problems.
Surgical Treatment
If all else fails, your doctor may recommend surgery. The goal of surgery is to give the tendons more space so they no longer rub on the inside of the tunnel. To do this, the surgeon performs a surgical release of the roof of the tunnel.
This surgery can usually be done as an outpatient, which means that you won't have to spend the night in the hospital. It can be done using a general anesthetic, which puts you to sleep, or a regional anesthetic. A regional anesthetic blocks the nerves going to only a certain part of the body. Injection of medications similar to novocaine can block the nerves for several hours.
In surgery for de Quervain's tenosynovitis, you may get an axillary block, which puts the arm to sleep, or a wrist block, which puts only the hand to sleep. It is even possible to perform the surgery by simply injecting novocaine around the area of the incision.
Once you have anesthesia, your surgeon will make sure the skin of your forearm and wrist is free of infection by cleaning the skin with a germ-killing solution. The first step in the surgical release is to make a small incision along the thumb side of the wrist.
View steps of surgery:
1. Incision site.
The surgeon moves aside other tissues and locates the tendons and the tunnel. An incision is made to split the roof, or top, of the tunnel. This allows the tunnel to open up, creating more space for the tendons. The tunnel will eventually heal closed, but it will be larger than before. Scar tissue will fill the gap where the tunnel was cut.
The skin is then stitched together, and your hand is wrapped in a bulky dressing.
Rehabilitation
What can I expect after treatment?
If conservative treatment is successful, you may see improvement in four to six weeks. You may need to continue wearing your thumb splint to control symptoms. Try to do your activities using healthy body and wrist alignment. Limit activities that require repeated motions of the wrist and thumb.
Rehabilitation is more involved after surgery. Full recovery could take several months.
Pain and symptoms generally begin to improve after surgery, but you may have tenderness in the area of the incision for several months.
Take time during the day to support your arm with your hand elevated above the level of your heart. You should move your fingers and thumb occasionally during the day. Keep the dressing on your hand until you return to the doctor. Avoid getting the stitches wet. Your stitches will be removed ten to fourteen days after surgery.
You will probably need to attend occupational or physical therapy sessions for six to eight weeks. You'll begin doing active hand movements and range-of-motion exercises. Therapists also use ice packs, soft-tissue massage, and hands-on stretching to help with the range of motion. When the stitches are removed, you may start carefully strengthening your hand and thumb by squeezing and stretching putty. Therapists also use a series of gentle stretches to encourage the thumb tendons to glide easily within tunnel.
As you progress, your therapist will give you exercises to help strengthen and stabilize the muscles and joints in the hand and thumb. Other exercises are used to improve fine motor control and dexterity. Some of the exercises you'll do are designed get your hand working in ways that are similar to your work tasks and sport activities.
Your therapist will help you find ways to do your tasks that don't put too much stress on your thumb and wrist. Before your therapy sessions end, your therapist will teach you a number of ways to avoid future problems.
