Official title
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.
Overview
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
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.
Interventions
- Device Magnesium-based bioresorbable DrillPin for fixation of distal radius fractures in children
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 Re
Primary outcome measures
- Number of participants with pain score <3 on the FACES® Pain Rating Scale (criterion of successful implantation) [Time frame: At 12 weeks postoperatively]
- Number of participants with radiographic healing in at least 3 of 4 cortices on two-plane radiographs (criterion of successful implantation) [Time frame: At 12 weeks postoperatively]
- Number of participants with at least one adverse event (AE), adverse device effect (ADE), serious adverse event (SAE), or serious adverse device effect (SADE) [Time frame: From day of surgery through 12 weeks postoperatively]
Secondary outcome measures (2)
- Passive wrist range of motion (ROM) in degrees measured to assess functional recovery [Time frame: 2, 4, 6 (optional), 12, 26, 52, and 104 weeks postoperatively]
- Number of participants with radiographic evidence of growth disturbance (growth arrest or length discrepancy) [Time frame: At 52 and/or 104 weeks postoperatively]
