Background
The aim of this study was to evaluate the efficacy of a semi-quantitative simplified 4-grade fat infiltration measurement system, described for the first time in literature, through comparison with the existing simplified 3-grade fat infiltration system in the prediction of lumbar disc herniation.
Material and Method
The study included 39 lumbar disc herniation patients (LDH) and 38 healthy subjects (control), comprising 33 (42.9%) males and 44 (57.1%) females with a mean age of 37 ± 11.3 years (range, 20–64 years). The patients were evaluated in respect of fat infiltration of the right and left lumbar multifidus and erector spina muscles on axial magnetic resonance imaging slices passing through the centre of the disc at L3-S1 level using the 3 and 4-grade fat infiltration measurement systems. The results were compared and the correlations of the results of the two systems with lumbar disc herniation were examined.
Results
The 3-grade fat infiltration system was found to be insufficient in the prediction of lumbar disc herniation (p > 0.05) and the 4-grade fat infiltration system was determined to be effective in the prediction of lumbar disc herniation (p = 0.003).
Conclusion
The 4-grade fat infiltration system was seen to be more effective than the 3-grade fat infiltration system in the determination of the level of fat infiltration in the paraspinal muscles and the prediction of lumbar disc herniation. The 4-grade fat infiltration system is an effective semi-quantitative grading system which can be used instead of the simplified 3-grade system.
