Trigger Finger

A trigger finger or trigger thumb is also known as 'Stenosing Tenosynovitis'.

The ability of the fingers and thumb to flex is a result of tendons pulling around a series of pulleys on the palmar side of the finger. The tendons originate from muscles in the forearm that travel through a tunnel in the wrist and subsequently through the flexor sheath.

Without these pulleys the tendon would bowstring forward resulting in decreased strength and grip.

A trigger finger results when the tendon develops a nodule or if there is swelling of the finger. This results in a popping or catching sensation. Sometimes the swelling may result in complete blockage of the tendon and the opening of the sheath making it difficult to straighten the finger.

Trigger fingers may not have a cause. Medical conditions such as rheumatoid arthritis, diabetic or underlying gout may be identified resulting in trigger fingers.

The surgery

The flexor sheath is widened by surgical division, and this results in rapid and usually complete resolution of the triggering.

Surgery is usually performed under a general anaesthetic as a day case at either Hollywood or Glengarry Hospitals.

Before surgery

Your anaesthetist will visit you on the day of procedure following admission. There is not normally a need to consult with the Anaesthetist prior to the operating day, we do suggest you make contact if you have had any of the following:
  • Head or Heart Surgery
  • Lapband Insitu
  • Blood Thinning Medication
  • Relevant Medical History.

After surgery

Post-operatively the hand is dressed and elevated as much as possible to attempt to minimise swelling.

Early finger movement is strongly encouraged, especially straightening.

Normal movement and function of the hand may be commenced almost immediately.

At home
