But on the flip side, both types of surgery for trigger finger are relatively simple procedures that can usually be done on an outpatient basis. There are two main types of trigger finger or thumb surgery: open and percutaneous. Both of these procedures involve the doctor âreleasing,â or splitting the A1 pulley through which the tendon is having trouble passing. The difference between these trigger finger surgeries is how the doctor goes about doing so.
1 Trigger finger is a type of tendinitis which develops in the tendons which bend the fingers. 2  It is a common problem because of the way that the hand is made, which may be a little different than you would suspect. 3  There are no muscles in the fingers themselves.4  We actually move our fingers by remote control. Tendon swelling (tendinitis) results from a person's own tendency to collect fluid around their tendons and joints. 2  This may be aggravated by repetitive or strenuous activities. 3  When the tendons which bend the fingers (the flexor tendons) become irritated, they can cause pain, swelling, and stiffness.
