Spring finger

What is it?

What is it?

A spring finger, also known as trigger finger, is a condition in which the tendon covering (tendon sheath) of the finger becomes inflamed and thickened, making it harder for the finger to move. The medical term for this condition is stenosing tenosynovitis.

Symptoms

Symptoms

The symptoms of a trigger finger vary.

  • You may experience sensitivity or pain on the affected thumb or finger.
  • The finger or thumb may get stuck in a bent position. This is characteristic of a trigger finger, where the finger appears to ‘spring up' when straightened.
  • An audible clicking or snapping sound may occur when moving the finger.
  • In some cases, swelling may occur around the affected area.

Symptoms may start gradually and then increase in severity. More than one finger may be affected at a time, and both hands may be involved.

A trigger finger is usually more pronounced in the morning, when you grasp an object firmly or when you stretch your finger.

Causes

Causes

The causes of a trigger finger are often associated with tendon issues and the surrounding tissue in the hand. Patients whose work or hobbies require repetitive grasping movements are at greater risk of developing a trigger finger. The condition is also more common in women and in people with diabetes or who have rheumatoid arthritis.

Treatment

Treatment

Treatment of a trigger finger can vary depending on the severity of symptoms. Possible treatments include rest, physical therapy, wearing splints, anti-inflammatories and, in some cases, surgery (see below) to open the tendon sheath.

Much depends on the severity, type of trigger finger and the presence of any other conditions. A comprehensive clinical examination allows the correct diagnosis to be made and the appropriate treatment to be given.

A spring finger release, or trigger finger release, is a surgical procedure that relieves the tendon entrapment in a finger.

A small incision is made along the skin lines, at the level of the first tension band. The skin line is opened and any adhesions between the tendons are loosened. Afterwards, the skin is closed with some sutures.

During keyhole surgery, the surgeon opens the tendon sheath through a small incision, eliminating any friction and blockage with the flexor tendon. The tendon may then swell. Sutures are not necessary with this surgery. The minor wound heals completely on its own.

This technique can only be performed on trigger fingers with a clear blockage, without contracture (forced position).

In patients who have severe swelling of the tendons and contracture (fixed position), it is sometimes insufficient to only open the first tension band of the tendon sheath and release the tendons. In these cases, it may be useful to remove half of the superficial tendon (i.e. an ulnar slip resection). For this procedure, the surgeon makes two small incisions that he then closes with a few sutures.

The procedure does not affect your muscle strength. Afterwards, you can perform any movement again.

Preparing for your admission

Preparing for your admission

To assess your health status before the procedure, you need to complete a questionnaire. Your attending physician will decide with you whether to do this through the pre-admission desk at the hospital or through the digital patient platform MyHospital.

Two working days prior to your procedure, a hospital staff member will call you to inform you what time you are expected at the hospital.

In consultation with your physician, take extra vitamin C in preparation for the surgery and your recovery.

Day of admission to hospital

Day of admission to hospital

The procedure requires a day admission. That means you can return home on the same day and do not have to overnight at the hospital.

On the day of your admission, come to the hospital at the appointed hour having fasted and sign in with your identity card via one of the e-kiosks in the atrium (entrance hall).

You get a ticket via the e-kiosk with a tracking number on it that is shown on the digital screens in the waiting area. A staff member will complete your file and you will receive an identity bracelet with your last name, first name and date of birth. After that, your admission will continue through the OR reception lounge.

You will be prepped for surgery in the operating facilities. The procedure is usually done under local anaesthetic. The anaesthetist will visit you to administer this. Feel free to ask any further questions you may have about the anaesthesia or the procedure.

After the procedure, you will be taken to our pleasant recovery lounge. The nurse will checks your vital parameters while you rest and recover from the surgery. This procedure promotes a quick and smooth discharge, allowing you to leave the hospital easily.

Aftercare

Aftercare

After the procedure, you will receive a hand bandage. You can remove the bandage the day after the procedure. You then cover the wound with a simple plaster.

  • Open trigger finger release: the sutures should be removed 12 to 14 days after the procedure.
  • Ultrasound trigger finger release: the wound heals spontaneously after a few days. For open release, the sutures should be removed after 12-14 days.
  • Ulnar slip resection:

soon after the treatment, try to perform full movements with your finger. While doing so, close your finger then extend it fully. You can resume all activities immediately. Please bear in mind that local discomfort or swelling after the surgery is normal.

You will have your first check-up appointment after X days.

Possible complications

Possible complications

For the first few days after the procedure, keep your hand elevated to prevent your fingers from swelling. Moving your fingers also helps reduce this swelling. You can also ice your fingers for 20-minute periods. Anti-inflammatories help reduce the swelling, but should only be taken on the advice of your attending physician.

A scar on the hand becomes softer after about four months. Be patient. After the wound heals, you can massage the scar to loosen it up. Moisturising creams or a silicone covering (Mepitac tape) may also be useful. Always protect the scar from sun exposure.

A compression bandage or cast may be applied to prevent excessive swelling. If the above advice does not help, you can loosen the elastic bandage or remove the hand bandage. The elastic bandage in an open cast can also be loosened.

The post-operative hand bandage will absorb any potential bleeding. Elevating the hand and applying ice can also help. Anti-inflammatory medication is possible, but it must be taken in consultation with your physician

This complication occurs very rarely, but it occurs more frequently in smokers and diabetics. Contact your physician or the A&E in case of sharply increasing pain, fever (>38.5°C), a festering wound or increasing and spreading redness.

Very rarely, temporary loss of sensation in the fingers may occur due to pressure from the bandage or swelling. Elevate the hand, loosen the elastic bandage and put ice on it. Contact our department if you have any concerns.
