    Storing removed bone flaps in the abdominal wall instead of refrigeration significantly reduces resorption during autologous cranioplasty for brain-injured patients. This method preserves bone viability, improving outcomes and patient stability.

    Area of Science:

    • Neurosurgery
    • Biomaterials Science

    Context:

    • Decompressive craniotomies are common for brain-injured patients, often involving bone flap removal.
    • Traditional bone flap storage (refrigeration) leads to significant osteolysis and instability in ~60% of subsequent cranioplasties.
    • This resorption necessitates further surgical intervention and impacts patient well-being.

    Purpose:

    • To evaluate an alternative method for preserving bone flaps after decompressive craniotomy.
    • To assess the efficacy of subcutaneous abdominal wall implantation for maintaining bone flap viability and reducing resorption.
    • To compare outcomes of abdominal wall storage versus traditional refrigeration for autologous cranioplasty.

    Summary:

    • A novel technique involves immediate subcutaneous implantation of removed bone flaps into the abdominal wall, bypassing refrigeration.

  • Over three years, 43 patients underwent this procedure, with bone flaps reimplanted weeks to months later.
  • This method resulted in significantly decreased bone resorption, with only 2 of 43 patients showing resorption at 1-2 year follow-up; one flap was lost to infection.

    • Impact:

    • Demonstrates a substantial reduction in autologous bone graft resorption following decompressive craniotomy.
    • Offers a viable alternative to refrigeration, enhancing bone flap survival and improving cranioplasty success rates.
    • Potentially reduces the need for revision surgeries and improves long-term patient outcomes and stability.
