Study summary

Patients who have undergone arthrodesis of the first metatarsophalangeal joint due to hallux valgus or hallux rigidus are invited to participate in this study, which aims to investigate how the foot functions after this operation. Patients between 18 and 60 years of age at the time of surgery are eligible to participate. Questionnaires will be distributed to assess current sports function compared with function prior to surgery. Particular focus will be placed on function during cross-country skiing.

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 May 27, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
