To assess differences in mechanical and histological osseointegration between two custom 3D-printed titanium implants with varying pore sizes and porosities, specifically focusing on their performance in a sheep model.
Key Findings:
No significant differences in mechanical strength (p = .87), energy (p = .80), or stiffness (p = .66) between P1 and P2, indicating comparable performance.
Histomorphometric analysis showed no significant differences in bone or fibrous tissue fractions.
No foreign body reaction was observed in any specimen.
Interpretation:
The study found no statistically significant differences in early osseointegration between the two implant designs.
Limitations:
The study was limited to a non-weight-bearing model, which may not fully represent clinical conditions.
Further research is needed to evaluate performance under weight-bearing conditions to better understand the implants' efficacy.
Conclusion:
Future investigations should explore the performance of these implant designs in more dynamic settings, particularly under weight-bearing conditions and with larger sample sizes.

In this procedural case review, vascular surgeon Dr. Samuel Steerman and neurosurgeon Dr. Shannon Clark collaborate to perform an anterior lumbar interbody fusion (ALIF).
