Is this trial a fit for you?

Likely a good fit

Adults 18 years and older with isolated syndesmotic injury or bi-/trimalleolar fractures involving the syndesmosis, who consent to participate.

Probably not a fit

Patients with inadequate trauma, osteoporosis, polytrauma, prior ankle surgery, advanced osteoarthritis, systemic inflammatory or degenerative conditions, or those unable to consent may not benefit.

What this trial studies

This prospective, single-center pilot study evaluates the function and integration of a bioresorbable magnesium set screw (ZX00) used to fix the syndesmosis in isolated syndesmotic injuries and in bi- or trimalleolar fractures. Participants undergo standard surgery and complete patient-reported outcome measures (NRS, AOFAS, FAAM) at baseline, 2, 4, 6, 12 weeks, and 12 months. Imaging with CT scans at 12 weeks and 12 months assesses implant resorption and integration, while follow-up visits monitor safety and healing. The study focuses on implant performance over 12 weeks and 1 year postoperatively in an elective orthopedic setting.

Why it matters

Potential benefit: If successful, patients could benefit from a resorbable fixation that may eliminate need for hardware removal and support bone healing.

How similar studies have gone: Prior work with bioresorbable implants in orthopedic injuries has shown mixed but promising results; this pilot aims to provide focused data on magnesium-based fixation for the syndesmosis.
