Summary

Fresh-frozen femoral allografts effectively treat spinal tuberculosis, showing good incorporation and neurological recovery. This study suggests allografts are a viable alternative for anterior spinal reconstruction.

Area of Science:

  • Orthopedics
  • Neurosurgery
  • Infectious Diseases

Background:

  • Spinal tuberculosis (TB) can cause neurological deficits and spinal deformity.
  • Anterior spinal decompression and reconstruction are crucial for managing spinal TB.
  • Graft incorporation and long-term stability are key concerns in spinal reconstruction.

Purpose of the Study:

  • To evaluate the incorporation and efficacy of fresh-frozen femoral allografts in patients with spinal tuberculosis.
  • To assess the ability of allografts to maintain spinal correction after anterior decompression.
  • To compare allograft outcomes with traditional autologous grafts.

Main Methods:

  • Retrospective evaluation of 52 patients with spinal TB who underwent anterior spinal decompression and reconstruction with fresh-frozen femoral allograft.

  • Assessment of allograft incorporation via imaging.
  • Evaluation of neurological recovery and spinal alignment (kyphosis) at a mean follow-up of 6.5 years.
  • Main Results:

    • Allograft incorporation was observed in 49 out of 52 patients.
    • Complete neurological recovery was achieved in 39 patients.
    • Mean kyphosis improved from 37 degrees pre-operatively to 18 degrees post-operatively, with sustained correction.

    Conclusions:

    • Fresh-frozen femoral allografts demonstrate successful incorporation and efficacy in treating spinal tuberculosis.
    • Allografts provide a suitable alternative to autologous bone grafts for anterior column reconstruction in spinal TB.
    • This approach effectively restores neurological function and maintains spinal alignment.
