Study compares calcium phosphate and iliac crest autograft performance in rabbits, suggesting implications for spinal fusion techniques.

Fusion rates were similar for calcium phosphate materials and iliac crest autograft over time.
sCaP with collagen showed earlier fusion compared to microstructured CaP at 9 weeks, indicating better performance.
All graft materials produced new bone with no adverse reactions, enhancing their clinical viability.
Differences in composition of calcium phosphate materials influenced spinal fusion outcomes in the model.

Walsh et al. (2025) studied this question.
