Platelet-rich plasma for the spinal fusion

Area of Science:

• Orthopedics
• Regenerative Medicine
• Biomaterials

Background:

• Platelet-rich plasma (PRP) is investigated for enhancing spinal fusion.
• Existing reviews focus solely on clinical data, lacking comprehensive analysis of animal models and PRP composition.

Purpose of the Study:

• To review literature on PRP's effect on spinal fusion in both animal models and clinical studies.
• To analyze the impact of platelet count and growth factor concentration in PRP on spinal fusion outcomes.

Main Methods:

• A PubMed search identified relevant English-language articles.
• Included 16 case-control or prospective randomized studies on spinal fusion.
• Categorized studies into small-sized animal, middle-sized animal, and clinical models.

Main Results:

• Studies reported both beneficial and inhibitory effects of PRP on spinal fusion.
• No definitive conclusion was reached regarding PRP's general stimulating effect on spinal fusion.
• Potential for PRP to promote human spinal fusion exists if platelet count or growth factor concentration is increased.

Conclusions:

• The efficacy of PRP for spinal fusion is inconclusive and may depend on specific parameters.
• Optimizing platelet count and growth factor concentration in PRP could enhance spinal fusion success.
• Further research is needed to establish PRP's role and optimal preparation for spinal fusion.
