Artificial lamina prostheses can prevent complications after laminectomy, a spinal decompression surgery. This review explores current artificial lamina designs and proposes a new perspective using additive manufacturing for improved spinal support.

Area of Science:

  • Spinal surgery
  • Biomaterials engineering
  • Medical device design

Background:

  • Laminectomy is a common spinal decompression procedure for various spinal disorders.
  • Post-laminectomy complications include loss of bony support, epidural fibrosis, and instability, often necessitating revision surgery.
  • Artificial lamina prostheses offer a solution to mitigate these complications by replacing resected bone and providing structural support.

Purpose of the Study:

  • To review complications associated with laminectomy.
  • To highlight the necessity and benefits of artificial lamina implantation.
  • To propose a novel design approach for artificial laminae.

Main Methods:

  • Review of clinical practice and laboratory research on artificial laminae.
Keywords:
