"Multicenter Registry for Chest Wall Reconstruction Using Custom Dynamic Prostheses (PRODIPET)"

PRODIPET Study Summary

Title: Multicenter Registry for Chest Wall Reconstruction Using Custom 3D-Printed Titanium Prostheses

Purpose

The PRODIPET study evaluates the safety and effectiveness of personalized, dynamic titanium prostheses for reconstructing the chest wall after:

Tumor resection (e.g., sarcomas, lung cancer). Severe trauma (e.g., multiple rib fractures). Traditional methods (metal plates, mesh) often lack flexibility, potentially causing pain or breathing difficulties. This study tests 3D-printed titanium implants designed to mimic natural rib movement, improving function and comfort.

Study Design

Type: Multicenter, ambispective (retrospective + prospective data).

Duration:

Prospective: 24 months (Jan 2024-Jan 2026). Follow-up: 12 months per patient (final analysis by 2027). Centers: Major Spanish hospitals (Ramón y Cajal/Madrid, La Ribera/Alzira, Cruces/Baracaldo, Insular/Las Palmas).

Key Goals

Assess short/mid-term outcomes (pain, breathing, complications). Compare results across patients/surgical techniques. Improve future prosthesis designs. Who Can Participate?

Inclusion:

Adults (18+) needing chest wall reconstruction. Signed consent for anonymized data sharing.

Exclusion:

Titanium allergies. Participation in conflicting studies. Patient Experience

Pre-Surgery:

CT scan creates a custom 3D prosthesis (made by Osteobionix® using Ti6AL4V-ELI titanium).

Surgery:

Surgeons implant the prosthesis, anchoring it to ribs/sternum.

Follow-Up:

Evaluations at discharge, 1/6/12 months (in-person or phone). Measures: Pain, lung function, imaging (X-ray/CT), complications (e.g., infection, implant failure).

Privacy \& Ethics

Data is anonymized and stored securely (REDCap system). Complies with European General Data Protection Regulation (EU GDPR) and Spanish data protection laws.

Patients may withdraw anytime. For Healthcare Providers

Collaboration: Open to thoracic surgeons/researchers. Data Access: Centralized via REDCap; analyzed by the coordinating team. Publications: Multicenter results will be published first; individual centers may later share their data.

Why This Matters

Addresses a gap in evidence for dynamic prostheses, which may offer:

Better breathing mechanics vs. rigid materials. Fewer long-term complications (e.g., breakage). Could standardize best practices for complex reconstructions. Contact
