Purpose: To report the clinical outcomes of percutaneous A1 pulley release for the surgical treatment of locked trigger thumb in children.
Materials and Methods: Twenty-six trigger thumbs in 24 patients with a average of 14.2 months follow-up after percutaneous release were enrolled. There were 15 females and 9 males with an average age of 39 months. The mean time from first presentation to surgery was 16 months. Procedures were performed under local anesthesia. Postoperative examinations at immediate, 3 months and 1-year recorded pain, triggering and range of motion and presence of complications.
Results: All thumbs had a satisfactory result without digital nerve injury. Eleven patients(46%) had a mean 14.3˚ extension loss of the interphalangeal joint and 12.0˚ hyperextension of the metacarpophalangeal joint of the thumb, compared to the contralateral thumb. At final follow-up, all but 1 patient were completely resolved. The duration of symptoms and age were higher in the group with thumb deformity (p<0.05).
Conclusion: Temporary thumb deformity is possible after surgical treatment of trigger thumb in children with a long duration of symptoms. Percutaneous release can be a safe and satisfactory treatment option in pediatric trigger thumb.
