Alternatives to autologous bone grafting in spinal surgery, such as allografts and synthetic materials, offer viable options when autograft is limited. These substitutes can achieve fusion, avoiding donor-site morbidity.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Regenerative Medicine

Background:

  • Autologous bone graft is a standard for spinal fusion but faces limitations in quantity and donor-site morbidity.
  • Alternatives are crucial for augmenting bone healing and stability in spinal procedures.

Purpose of the Study:

  • To review current bone grafting alternatives in spinal surgery.
  • To provide insight into modulating cellular bone healing and reversing disc degeneration.

Main Methods:

  • Systematic review of contemporary English literature on bone grafting in spinal surgery.
  • Evaluation of alternatives for efficacy in spinal applications, extending or replacing autograft.

Main Results:

  • Alternatives include allograft bone, demineralized bone matrix, recombinant growth factors, and synthetic implants.

  • Substitutes can be combined with bone marrow or growth factors.
  • No single substitute fully replicates autograft's osteogenicity, osteoconductivity, and osteoinductivity but shows clinical utility.

    • Conclusions:

    • Bone graft alternatives are valuable when autograft is limited or fusion is achievable without allograft properties.
    • These substitutes help avoid autograft harvest morbidity.
    • Future research may focus on material combinations to achieve autograft-like properties.
