What this trial studies

This observational study aims to collect prospective data from approximately 3,500 patients with various extremity fractures, including hip, tibial, ankle, humeral, and radius fractures. Patients will be followed for up to one year post-treatment, with data collected on underlying conditions, treatment details, patient-reported outcomes (PROs), and any complications. The study includes sub-projects focusing on individualized treatment based on sensor data, defining recovery trajectories using PROMIS measures, and linking PROMIS scores to traditional orthopedic measures. The goal is to optimize decision-making and improve patient outcomes following extremity fractures.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with isolated extremity fractures who can communicate in English, German, or Spanish.

Not a fit: Patients with multiple fractures, pathological fractures due to cancer, or those with recent substance abuse issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance recovery strategies and improve outcomes for patients with extremity fractures.

How similar studies have performed: Other studies have shown promise in using patient-reported outcomes and sensor data to improve recovery trajectories, making this approach both relevant and potentially impactful.
