Characteristics of Spinopelvic Sagittal Alignment in Lumbar Degenerative Disease.

World neurosurgery·2019

Tubular discectomy shows potential for improved functional recovery and reduced vertebral translation compared to classic microdiscectomy. While not statistically significant, the tubular approach may lead to less postoperative pain.

Area of Science:

  • Spine surgery
  • Orthopedics
  • Neurosurgery

Background:

  • Spinal instability arises from an imbalance between bony and soft tissues.
  • Midline surgical approaches may compromise spinal stabilizing tissues, increasing instability risk.
  • Degenerative processes like arthrosis and discal disease are linked to this imbalance.

Purpose of the Study:

  • To compare dynamic instability between tubular discectomy and classic microdiscectomy.
  • To evaluate differences in disc degeneration, pain, and functional outcomes.
  • To assess surgical factors such as blood loss and duration.

Main Methods:

  • Retrospective, observational cohort study of adult patients undergoing discectomy (2016-2023).
  • Comparison of radiological measurements (Cobb angles, AP movement) between tubular and classic approaches.

  • Analysis of Magnetic Resonance Imaging (MRI) findings, pain scores (VAS), and functional scores (Oswestry, Roland).

    • Main Results:

    • Tubular discectomy demonstrated significantly lower intraoperative blood loss.
    • Postoperative outcomes favored the tubular group with improved functional scores (Oswestry, Roland, VAS) and extension angles.
    • Multivariate analysis showed reduced vertebral translation in the tubular group compared to the open group (p=0.05).

    Conclusions:

    • A trend favors the tubular approach for reduced postoperative pain.
    • No general radiographic or MRI differences were found between the groups.
    • Tubular discectomy may offer advantages in functional recovery and spinal stability.
