Stenosing Tenosynovitis
(Trigger Finger/Thumb)

Trigger finger is a "catching" of the tendon when a finger or thumb is extended due to swelling of the tendon sheath. Causes are unclear but do commonly occur in people with diabetes or arthritis.

Non-surgical treatment is by way of splinting the finger and anti-inflammatory medication, but if this is unsuccessful, surgery may be indicated. Surgery to relieve the triggering is usually done as a day only procedure under a general anaesthetic with torniquet control, releasing the spot where the tendon catches. Patients can usually return to work within the week.
