Recombinant bone morphogenic protein-2 in orthopaedic surgery: a review

Area of Science:

• Orthopedics
• Regenerative Medicine
• Biomaterials

Background:

• Bone morphogenic proteins (BMPs) are crucial regulators of bone volume, skeletal development, and fracture repair.
• BMPs act as signaling molecules influencing cellular proliferation, differentiation, and extracellular matrix synthesis.

Purpose of the Study:

• To review the development, molecular properties, toxicity, and clinical applications of recombinant human BMP-2 (rhBMP-2).
• To highlight the expanding use of rhBMP-2 in orthopedic trauma, specifically open tibia fractures.

Main Methods:

• Literature review of BMPs and rhBMP-2.
• Analysis of historical development and clinical utilization data.
• Examination of molecular characteristics and toxicity profiles.

Main Results:

• rhBMP-2, combined with an osteoconductive carrier, functions as a bone graft substitute promoting bone growth.
• Initially approved in 2002, rhBMP-2 has been predominantly used in spinal fusions (lumbar and cervical).
• Recent applications have expanded to orthopedic trauma, notably in treating open tibia fractures.

Conclusions:

• rhBMP-2 represents a significant advancement in bone regeneration therapies.
• The expanding clinical applications underscore its versatility and efficacy in various orthopedic settings.
• Further research into its long-term effects and broader applications is warranted.
