Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

RemeOs™ DrillPin for Fixation of Distal Radius Fractures

Group Type EXPERIMENTAL

Magnesium-based bioresorbable DrillPin for fixation of distal radius fractures in children

Intervention Type DEVICE

This is a first-in-child clinical investigation of a bioresorbable magnesium alloy DrillPin (RemeOs™) for fixation of distal radius fractures in children aged 5 to \<14 years. The implant is investigational, not CE-marked or FDA-approved, and represents a novel alternative to traditional metallic implants. It gradually degrades in vivo, eliminating the need for removal. The study focuses on safety and feasibility in a pediatric population, supported by preclinical data from a similar Mg-based RemeOs™ Screw. The DrillPin's material and design are intended to support bone healing without growth disturbances, offering a state-of-the-art, bioresorbable solution tailored for growing patients.
