RemeOs™ DrillPin for Fixation of Distal Radius Fractures in Children

To Evaluate the Feasibility of the Clinical Application of Mg-based RemeOs™ DrillPin for Fixation of Fractures of the Distal Radius in Children From the Age of Over 5 and Under 14.

This is a pre-market, single-arm, open-label, monocenter clinical investigation evaluating the safety and performance of the magnesium (Mg)-based bioresorbable RemeOs™ DrillPin for surgical fixation of distal radius fractures in pediatric patients. The study will enroll 20 children aged over 5 and under 14 years to assess implantation success, early safety outcomes, and long-term effects on growth and bone healing.

This single-arm, open-label, monocenter clinical investigation is conducted in accordance with ISO 14155 to evaluate the safety and performance of the RemeOs™ DrillPin (a bioresorbable magnesium-based implant) used for internal fixation of distal radius fractures in pediatric patients.

Eligible participants are children aged over 5 and under 14 years who require surgical fixation of a distal radius fracture. The RemeOs™ DrillPin is designed to offer stable fracture fixation while gradually resorbing in the body, potentially reducing the need for implant removal.

Primary objectives include evaluating implantation success-defined by low pain levels (FACES® Pain Rating Scale score <3) and radiographic fracture healing in at least three cortices out of four across two imaging planes at 12 weeks postoperatively-and assessing short-term safety by monitoring adverse events, including device-related and serious adverse events.

Secondary assessments focus on postoperative clinical function and wrist range of motion (ROM), measured using a goniometer, as well as radiographic markers of implant biodegradation. Long-term safety is evaluated through the monitoring of potential growth disturbances at 52 and 104 weeks, including limb length discrepancies or growth plate abnormalities.

This early-stage investigation aims to generate clinical data on the application of magnesium-based resorbable implants in pediatric fracture care and to assess their potential to support bone healing without interfering with skeletal development.
