Conditions congenital trigger thumb, tenosynovitis
Sponsor University of Utah
Start date December 2010
End date January 2018
Trial size 100 participants
Trial identifier NCT01424995, 32047


This will be a prospective study of all children ages 0 - 5 years old at the time of entry into the study that meet the inclusion criteria who present with congenital trigger thumb. Patient records will be reviewed for eligibility before obtaining parental permission. They will be enrolled in the study at their first visit and followed every year for up to 4 years or until one of the exclusion criteria are met. Participating sites include the University of Utah Orthopaedic Center, Primary Children's Medical Center and Shriners Hospital for Children.

Primary Outcomes

The goal of this study is to prospectively evaluate the natural history of congenital trigger thumbs to determine the true incidence of spontaneous resolution.
time frame: 4 years

Eligibility Criteria

All participants up to 5 years old.

Inclusion Criteria: - Diagnosis of congenital trigger thumb based on physical exam and history, no previous treatment history (either operative or non-operative), no pain associated with the deformity, no functional disability due to the trigger thumb. Exclusion Criteria: - Previous operative treatment for the congenital trigger thumb, deformity of the thumb that causes pain, triggering that causes secondary deformity of the thumb, and deformity that prevents normal use of the thumb and hand.

Additional Information

Official title The Natural History of Congenital Trigger Thumbs
Principal investigator Douglas T Hutchinson, MD
Description Trigger thumb is a stenosis tenosynovitis of the flexor pollicis longus tendon of the thumb1. The eitiology of congenital trigger thumb is unclear with many authors proposing both hereditary and acquired causes2-4. Surgical release of congenital trigger thumbs has been recommended as definitive treatment, though controversy exists over the natural history of congenital trigger thumbs5-8. There have been a number of studies looking at the natural history of congenital trigger thumbs with spontaneous resolution rates ranging from 0-96% over a median duration of follow up that ranged from 6 months to 48 months9-14. Based on our clinical experience, the investigators do not feel that congenital trigger thumbs resolve spontaneously and that definitive treatment requires surgical release. However, the investigators need to do further scientific research into the natural history of trigger thumbs to determine how often trigger thumb resolves without needing surgical intervention.
