Researchers track nerve pain in ankle fracture patients
NCT ID NCT06420141
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 250 people who had ankle fractures to see how many develop nerve-related chronic pain after the bone heals. Participants answer pain questionnaires and undergo simple sensory tests. The goal is to better understand this type of pain, not to test any new treatment.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The investigators will enroll participants who have sustained rotational ankle (specifically AO/OTA 44 types AC) fractures that are treated operatively. Fracture patients will complete clinic assessment sessions at standard of care visits, including their first post-op appointment (2-3 weeks), at 6-8 weeks, at 3-4 months, and at 6-9 months post-operatively. These visits will allow assessments during the subacute and chronic stages of bone fracture associated neuropathic pain.
