Reliability of spondylolisthesis grading instruments varies. Slip percentage, Meyerding's grade, and sacral inclination showed excellent inter- and intraobserver agreement for assessing vertebral slippage.

Area of Science:

  • Orthopedics
  • Radiology
  • Spine Surgery

Background:

  • Spondylolisthesis, or vertebral slippage, commonly affects the lumbosacral junction in children.
  • Numerous radiographic measurement tools exist to predict spondylolisthesis progression and treatment needs.

Purpose of the Study:

  • To evaluate the reliability of eight commonly used grading instruments for spondylolisthesis.
  • To determine which radiographic measurements offer the most consistent assessment of vertebral slippage.

Main Methods:

  • Four independent raters assessed 30 lateral lumbar spine radiographs of patients with spondylolisthesis.
  • Each radiograph was measured twice by each rater to assess both interobserver and intraobserver reliability.
  • Correlation coefficients were calculated to quantify the agreement between measurements.

Main Results:

  • Three measurements demonstrated excellent interobserver reliability (correlation > 0.75): slip percentage, Meyerding's grade, and sacral inclination.
  • Six measurements showed excellent intraobserver reliability (correlation > 0.75), with only the kyphosis angle and lumbar index falling short.
  • Slip percentage, Meyerding's grade, and sacral inclination achieved excellent agreement for both interobserver and intraobserver assessments.

Conclusions:

  • Slip percentage, Meyerding's grade, and sacral inclination are reliable radiographic instruments for grading spondylolisthesis.
  • These specific measurements offer consistent and reproducible assessments, aiding in clinical decision-making for pediatric spondylolisthesis.
  • The study highlights the importance of selecting reliable measurement tools for accurate spondylolisthesis evaluation.
