Area of Science:

  • Veterinary Surgery
  • Neurosurgery
  • Biomedical Engineering

Background:

  • Intervertebral disc disease (IVDD) is a common condition in dogs.
  • Surgical fenestration aims to relieve pressure by removing nucleus pulposus.
  • Novel devices are needed to improve the safety and efficacy of fenestration procedures.

Purpose of the Study:

  • To evaluate the feasibility and effectiveness of a novel vacuum-assisted tissue resection device (VRD) for canine intervertebral disc fenestration.
  • To compare the VRD's performance against manual fenestration techniques.
  • To assess the safety and technical challenges associated with VRD use in canine cadavers.

Main Methods:

  • A randomized prospective study utilizing 15 canine cadavers.
  • Comparison of manual fenestration, VRD fenestration, and a control group.

  • Assessment of fenestration effectiveness by calculating the ratio of remaining nuclear weight to total nuclear volume; lower ratios indicate greater nucleus pulposus removal.

    • Main Results:

    • Both manual and VRD fenestration significantly reduced the remaining nuclear weight-to-volume ratio compared to controls (P < .001).
    • The VRD group showed a trend towards improved nucleus pulposus removal (ratio 0.23 ± 0.09) compared to manual fenestration (0.30 ± 0.10), though not statistically significant (P = .069).
    • Fenestration at lower lumbar levels (L5-L6, L6-L7) was technically more challenging and resulted in higher residual nuclear ratios compared to cranial levels (L4-L5) (P = .026 and P = .004, respectively).

    Conclusions:

    • The vacuum-assisted tissue resection device (VRD) is a feasible instrument for canine intervertebral disc fenestration.
    • The VRD demonstrates comparable effectiveness to manual fenestration.
    • The VRD offers potential advantages in safety features during the fenestration procedure.
