Trigger finger is a general term used in orthopedics to describe a condition where any one of the fingers becomes either partially or fully immobilized owing to a discrepancy between the size of the tendons extending the fingers and the sheath through which these tendons pass.
In partial trigger finger, the tendons encounter some friction or resistance when entering the tendon sheath. This results in a snapping sound whenever the fingers are extended. In complete trigger finger, the tendons get stuck in the sheath and will not extend at all. In both instances, the causes are fairly diverse, from a localized inflammation of the sheath or tendon to a swelling of the tendon that makes it disproportionate in size to the sheath.
Whatever the cause, the condition can be fairly painful and very uncomfortable. To treat this, trigger finger release is employed. This may be done in one of two ways. In the first instance, called percutaneous trigger finger release surgery, the surgeon will insert a needle into the base of your affected finger and use this to divide the pulley, releasing the tendon.
In the other type of treatment, referred to as open surgery, the surgeon will make a small cut into the palm of your hand at the base of your affected finger, and then release the tendon from the ligament (A1 pulley) that it is catching on.
