Trigger finger,
is a condition characterised by a finger
locking in a bent position.
When the
finger is forcibly straightened, inflammation
of the fibrous sheath stops the tendon sliding
smoothly back into the sheath. There is
usually a bump and tenderness at this site
of the obstruction. If the finger is straightened
there is a cracking or snapping sound.
The treatment
for trigger finger may be to inject anti-inflammatory
steroid around the tendon or to perform
a minor operation under local anaesthetic.
