Vertebrae Structure

  • Vertebral Body: The large, rounded portion that bears weight.
  • Vertebral Arch: A bony structure that encloses the spinal canal, formed by pedicles and laminae.
  • Spinous Process: The bony projection at the back of each vertebra, which can be felt along the spine.
  • Transverse Processes: Projections on either side of the vertebra that serve as attachment points for muscles and ligaments.
  • Intervertebral Discs: Cartilaginous pads between vertebrae that act as shock absorbers and allow for flexibility and movement.

Functions of spine cages

Spine cages are specialized implants used in spinal surgery, particularly in fusion procedures. Their primary purpose is to stabilize the spine and promote bone growth between vertebrae. Here are the key indications for the use of spine cages:

  1. Spinal Fusion
  • Degenerative Disc Disease: To provide stability and support during the fusion of degenerated discs.
  • Spondylolisthesis: To fuse and stabilize vertebrae that have slipped out of place.
  • Spinal Stenosis: To alleviate pressure on the spinal cord or nerves by promoting fusion and stability.
  1. Trauma
  • Fractures: To stabilize fractured vertebrae and support bone healing.
  • Dislocations: To restore alignment and provide support after dislocation injuries.
  1. Revision Surgeries
  • Failed Back Surgery Syndrome: In cases where previous surgeries were unsuccessful, cages can be used to achieve a successful fusion and stabilize the spine.
  1. Spinal Deformities
  • Scoliosis and Kyphosis: To support spinal alignment and stability during corrective procedures.
  1. Infection or Tumors
  • Tumor Resection: To stabilize the spine after the removal of spinal tumors.
  • Infections: In cases of spinal infections, cages can help stabilize the affected area while treatment is ongoing.
  1. Minimally Invasive Procedures
  • Spine cages are increasingly used in minimally invasive surgeries to reduce recovery time and minimize tissue damage.
  1. Interbody Fusion
  • Anterior and Posterior Approaches: Cages are commonly used in both anterior lumbar interbody fusion (ALIF) and posterior lumbar interbody fusion (PLIF) to facilitate bone growth and maintain disc height.
