Area of Science:

  • Biomedical Engineering
  • Thoracic Surgery
  • Materials Science

Background:

  • Complex chest wall defects require innovative reconstruction solutions.
  • Conventional rigid implants may have limitations in anatomical adaptation and flexibility.

Purpose of the Study:

  • To evaluate the technical feasibility and surgical safety of dynamic, 3-dimensional (3D) customized prostheses for complex chest wall reconstruction.
  • To assess outcomes in a multicenter experience using 3D-printed titanium implants.

Main Methods:

  • Retrospective observational study of 51 patients across 5 Spanish hospitals (2016-2023).
  • Utilized custom-designed, spring-like 3D-printed titanium implants for chest wall reconstruction.
  • Collected data on indications, demographics, operative details, complications, and follow-up outcomes.

Main Results:

  • Indications included oncologic (35), traumatic (11), infectious (3), and functional (2) cases.
  • 51 prostheses were implanted for various sternocostal, costal, costovertebral, sternoclavicular, and scapulothoracic reconstructions.
  • Mean operative time was 270 minutes; median follow-up was 2.5 years. Four minor complications occurred, with no implant removal or failure.

Conclusions:

  • Dynamic 3D-customized prostheses offer a stable yet flexible alternative to rigid implants.
  • Their design facilitates anatomical adaptation and intraoperative placement, enabling safe and reproducible reconstruction.
  • Feasible and safe option for complex or functionally demanding thoracic reconstructions with favorable medium-term outcomes.
