Hypothesis

Can a sheep model effectively test the biocompatibility of various biomaterials for bone replacement?

Conclusion

The sheep model is an excellent basis for testing the biocompatibility of novel biomaterials used for bone replacement.

Supporting Evidence

  • The model allows testing of up to 8 different materials in one animal.
  • Routine evaluation through histomorphometry is easily conducted.
  • Complications such as spontaneous fractures were not encountered when drill holes were correctly placed.

Takeaway

Researchers used sheep to test new materials that can replace bone, and found that this method works well without causing harm to the animals.

Methodology

The study involved creating drill holes in the bones of sheep to test various biomaterials for their compatibility and effectiveness.

Limitations

Some drill holes were not placed correctly, leading to complications in a few animals.

Participant Demographics

70 healthy ewes, White Swiss Alpine Sheep, aged 2 to 5 years, weighing 53 to 80 kg.
