De Quervain's Tenosynovitis
-
Thumb movements are powered by muscles in the forearm. The Muscles are connected to the fingers by tendons.
-
To stop the tendons from ‘bow stringing’ with wrist and finger movement, there is a tunnel formed by bone and ligaments at the wrist.
-
If there is swelling around a tendon, the tendon becomes thicker, or the tunnel narrower – the tendon cannot glide freely through its tunnel.
-
The area becomes inflamed and painful, especially with thumb movement
-
The most common cause is over use, that causes inflammation. Excessive use of scissors is an example.
-
Some people are prone to swelling and inflammation (synovitis) around their tendons. For example those with rheumatoid arthritis.
-
An injury such as a wrist fracture or a direct blow to the side of the wrist.
-
There can be a structural pre disposition, such as unusually shaped tendons.
-
If usually starts with tenderness on the wrist at the base of the thumb, that is aggravated by movement of the thumb.
-
In severe cases there can be crepitus (clicking and grinding) on thumb and wrist movement.
-
Avoid activities that cause pain in the finger. (Gripping, pinching, using scissors etc.)
-
Wearing a splint that stops the thumb from moving (it is usually fitted by a hand therapist).
-
Consider taking an anti inflammatory.
-
A steroid injection around the tendon can resolve the issue, or at least give relief for a while.
-
When non operative treatments (mentioned in the previous slide) is unsuccessful.
-
Surgery is usually the best option if De Quervains Tenosynovitis has been present for a long time
-
If you would prefer a definitive cure for the problem.
-
This kind of surgery is usually done under local anaesthetic with or without sedation (‘twilight anaesthetic’)
-
It is done as day case surgery in a hospital,
-
–but you cannot drive after the procedure and
-
–you should not be home alone on the night of the surgery.
-
Antibiotics are usually not necessary at the time of surgery.
-
The operation is done by a small incision on the side of the wrist.
-
The sheath around the tendon is released so that the tendon can glide freely
-
The wound is sutured and a dressing is applied.
In Hospital
-
There will be a bandage on the wrist.
-
It is important that the hand remains elevated ‘higher than your heart’ to help limit swelling
-
Usually the area is still numb from local anaesthetic.
-
It is usual to leave hospital an hour or two after surgery
​
At Home
-
It is usual for the hand to feel numb for about one day after surgery, due to the local anaesthetic.
-
Continue to elevate your arm until swelling in your wrist and fingers subside.
-
Please keep the bandage on the wrist in place until your first review at my rooms.
-
Move your thumb (touching the little finger and straightening it out fully about 10-20 times a day).
-
An appointment usually arranged at my practice nurse at about 1-2 weeks after surgery.
-
The wound usually heals over 1-2 weeks and any sutures are then removed
-
Self care (washing, dressing, eating) with the operated hand – usually around 5 days
-
Driving: when you are able to control a steering wheel with your operated hand and you are not taking strong pain relief anymore (usualy 5-10 days post surgery)
-
Most moderate activities(equivalent to lifting a pot of the stove or pouring a full kettle) can usually be tolerated by 4-6 weeks,
-
Scarring ate the site of the surgery, where the tendon sheath was divided can be slightly thick and tender for months (3-6).
-
Golf, fishing, cycling etc.: usually around 2-3 months, but it can be longer (6 months)
-
Occasionally there can be damage to a skin nerve, resulting in tingling, numbness and sensitivity at the scar and on the back of the hand.
-
Infection occurs rarely(1% of the time). It is rarely severe.
-
There may be ongoing pain from scarring, or other worn out joints in the area such as the joints at the base of the thumb
-
Sometimes the scar can be very sensitive and thick, limiting thumb and wrist movement.
-
Very rarely (around one in a thousand)a severe pain reaction , (CRPS) can develop, which can be disabling for years.
-
Rarely, the released tendons can become unstable and slip backwards and forwards over the side of the wrist as it moves.
-
A second tendon running in its own tunnel can be missed during surgery and can cause ongoing problems
-
A full recovery is usually expected from a De Quervains release.
