Purpose: To analyze the clinical patterns of trigger fingers and assess the effect of the steroid injection in percutaneous release.
Materials and Methods: Fifty-six patients with 68 trigger fingers that did not respond to nonoperative treatments were randomized to either percutaneous release alone (n=37) or percutaneous release with steroid injection (n=31) for surgical treatment of the A1 pulley. Grades of triggering according to severity and clinical type (nodular or diffuse) were assessed preoperatively. Duration of postoperative pain, graded results of surgical release, complications, and recurrence were assessed at 2-week, 4-week, 3-month, and 6-month follow-up examinations.
Results: Trigger fingers were successfully treated in 97% (30/31) of the cases using the percutaneous release with steroid injection and in 92% (34/37) of the cases using the percutaneous release alone. Mean duration of postoperative pain was significantly shorter in the percutaneous release with steroid injection group (p=0.002). For the cases of diffuse-type trigger finger, those treated by percutaneous release alone exhibited significantly longer duration of postoperative pain than those by the percutaneous release with steroid injection (p=0.003). No serious complications were observed in either group.
Conclusion: Percutaneous release of trigger fingers is a simple and usually successful procedure. In cases of diffuse-type trigger finger, percutaneous release with steroid injection provides better results than that of percutaneous release alone.
