Novel alternative therapy for spinal tuberculosis during surgery: reconstructing with anti-tuberculosis bioactivity...

Area of Science:

• Biomaterials Science
• Orthopedic Surgery
• Infectious Disease Research

Background:

• The global rise in tuberculosis (TB) has led to increased cases of spinal TB.
• Current materials for spinal TB reconstruction have limitations, necessitating new solutions.
• Effective spinal reconstruction and bone defect repair are critical for treating spinal TB.

Purpose of the Study:

• To explore the potential of Poly-DL-lactide (PDLLA) and nano-hydroxyapatite (nHA) for spinal TB reconstruction.
• To propose novel strategies for developing improved implants for spinal TB treatment.
• To address the deficiencies of existing materials in spinal TB surgery.

Main Methods:

• Discussed the properties of PDLLA and nHA as drug delivery systems and bone repair materials.
• Proposed a strategy involving 3D printing of a porous scaffold with anti-TB drugs, PDLLA, and nHA.
• Proposed a strategy of coating titanium mesh implants with drug/PDLLA/nHA composites using specific fabrication techniques.

Main Results:

• PDLLA and nHA are identified as promising candidates for drug delivery and bone repair in spinal TB.
• Two novel fabrication strategies for spinal TB implants were presented and tested in a laboratory setting.
• The developed materials and techniques show potential for overcoming current limitations in spinal TB reconstruction.

Conclusions:

• PDLLA and nHA offer a viable pathway for developing advanced materials for spinal TB.
• The proposed 3D printing and composite coating strategies represent innovative approaches to spinal TB treatment.
• Further research and clinical application of these novel materials could significantly improve surgical outcomes for spinal TB.
