Use of 3D-Printed Implants in Complex Foot and Ankle Reconstruction

Area of Science:

• Orthopaedic surgery
• Biomaterials science
• Regenerative medicine

Background:

• Traumatic critical-sized bone defects pose significant challenges in orthopaedics.
• Autografts are the gold standard for bone loss but are limited in larger defects.
• Novel strategies are essential for effectively reconstructing extensive bone voids.

Purpose of the Study:

• To review current techniques for managing large bone defects using 3D-printed implants.
• To discuss strategies for lower extremity trauma and bone loss.
• To explore future directions in implant design and peri-implant environment optimization.

Main Methods:

• Review of current literature on bone defect management.
• Discussion of established techniques: bone transport, Masquelet technique, osteomyocutaneous flaps, and massive allografts.
• Analysis of 3D-printed implant applications in orthopaedic trauma.

Main Results:

• 3D-printed implants offer promising solutions for complex bone defects.
• Various surgical techniques are employed to bridge large bone gaps.
• Optimizing implant design and the surrounding biological environment is crucial.

Conclusions:

• Effective treatment of critical-sized bone defects requires advanced strategies beyond autografting.
• 3D-printed implants and innovative techniques are vital for addressing lower extremity trauma.
• Future research should focus on implant customization and enhancing bone regeneration for better patient outcomes.
