    Osteogenin containing gelatine (OCG) effectively facilitated bone defect repair in sheep. OCG implants were fully resorbed, demonstrating a promising alternative for diaphyseal defect correction.

    Area of Science:

    • Biomaterials Science
    • Orthopedic Surgery
    • Regenerative Medicine

    Context:

    • Diaphyseal bone defects pose significant challenges in orthopedic treatment.
    • Current bone grafting methods have limitations, including donor site morbidity and graft rejection.
    • There is a need for innovative biomaterials to promote bone regeneration.

    Purpose:

    • To evaluate the efficacy of osteogenin containing gelatine (OCG) as an alternative material for correcting diaphyseal bone defects in a sheep model.
    • To assess the bone healing process radiologically and histologically.

    Summary:

    • Allogenic cortical bone prepared as OCG was implanted into diaphyseal defects in sheep, with a control group receiving no implants.
    • Radiological assessment at 3, 6, 9, and 12 weeks and histological examination at 12 weeks were performed.

  • Control animals showed no defect bridging. Four out of six OCG-treated animals demonstrated complete defect reconstruction by 9 weeks, with new spongy bone formation and complete OCG resorption by 12 weeks. Two OCG-treated animals experienced complications (infection and osteosynthesis failure).

    • Impact:

    • OCG demonstrates potential as a viable biomaterial for diaphyseal defect reconstruction.
    • The study highlights the osteoconductive and osteoinductive properties of OCG in a large animal model.
    • Successful OCG resorption suggests good biocompatibility and integration with host bone tissue.
