Study summary

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.

Read the detailed 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.

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

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.

What researchers measure

Primary outcomes

  1. The goal of this study is to prospectively evaluate the natural history of congenital trigger thumbs to determine the true incidence of spontaneous resolution.

    The following physical exam measurements will be made at the first visit and all subsequent visits until completion of the study: flexion contracture of the interphalangeal joint of both thumbs (resolution of deformity defined as when flexion contracture is 0°), metacarpal-phalangeal joint laxity, and amount interphalangeal joint angular deformity.

    Time frame: 4 years

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 15, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
