NCT05729542

Brief Summary

This project consists of a randomized controlled study design. Study candidates will include all patients 18 years or older, who were evaluated at UCSD and found to have an acute ankle syndesmosis injury requiring surgery. Patients who consent to study participation will be randomized to receive one of two standard of care procedures - either a suture button or Fibulink implant. Outcome measures, including the Olerud-Molander and American Orthopaedic Foot and Ankle Society scores, pain, range of motion, time to return to work, and radiographic evaluation will be collected for each participant. Given the potential degenerative changes and poor radiographic and clinical outcomes with inadequate repair of the syndesmosis, it is imperative to evaluate existing and emerging methods of fixation for patients with acute ankle fractures with syndesmosis injuries.

Outcome Measures

Primary Outcomes (3)

  • Visual Analog Scale (VAS) Pain score

    VAS Pain score is rated from 0-10, 0=no pain and 10=most severe pain

    1 year

  • Foot and Ankle Disability Index

    Functional score with a 0-104 with higher scores indicating better function

    1 year

  • Olerud-Molander Ankle Score

    Functional Score with a score of 0-100 with higher scores indicating better function

    1 year

Secondary Outcomes (1)

  • Number of participants with medical or surgical complications

    1 year
