What is it?
The tendons that bend your fingers run through a tunnel or sheath. Trigger finger is caused by a thickening on the tendon, which causes it to catch as it runs in and out of the sheath. You can often feel this swelling in the palm as you move the finger. Patients complain of pain in the palm at the base of the affected finger and episodes of the finger being stuck, bent down. This can be relieved by pushing the finger out straight, causing a snap which can be painful. Patients often wake in the morning with the finger stuck down.
What can be done?
There are two ways of treating the problem.
After the operation, you will be in a big bandage, but the fingers will be free to move. It is important to move all fingers and thumb straight away, as well as keep the hand raised (above the level of your heart) for at least 72 hours to help with swelling and stiffness.
This bulky dressing can be taken down at 72 hrs and a light sticky dressing applied to the wound. There will initially be some swelling and bruising, however, if you have any worries contact your G.P (i.e increasing pain, swelling, redness) The stitches are usually dissolvable. You will be reviewed in the Orthopaedic clinic at 2- 6 weeks. Timing of your return to work is variable according to your occupation and you should discuss this.
Any operation can be followed by infection and this would be treated with antibiotics.
You will have a scar on the palm. This will be somewhat firm to touch and tender for 6-8 weeks. This can be helped by massaging the area firmly with moisturizing cream.
About 5% (1 in 20) of people are sensitive to hand surgery and their hand may become swollen, painful and stiff after any operation (Complex regional pain syndrome).This problem cannot be predicted but will be watched for afterwards and treated with physiotherapy.
The nerves running to the fingers can be damaged during the surgery and cause numbness in part of the finger. This is very rare.
As mentioned above, the triggering can recur. However this is rare.
