Summary

This study examined whether there is an association between the presence of lumbar intervertebral disc degeneration (LDD) and the size and symmetry of the cross-sectional areas (CSAs) of the trunk muscles in combat sports athletes. Participants in this study were collegiate combat sports athletes. All intervertebral discs from L1/2 to L5/S1 in all athletes were assessed using MRI and a comprehensive grading system of LDD (grades I-V). All 151 athletes were divided into 2 groups: LDD and non-LDD. CSAs of trunk muscles at the L3/4 disc level were measured on MRI.

Conditions

  • Other Intervertebral Disc Degeneration, Lumbar Region

Interventions

DEVICE

Lumbar disc degeneration; LDD

All MR images, taken at 5 lumbar intervertebral disc levels from the first lumbar (L1) vertebra to the first sacral vertebra (S1), were independently evaluated by 2 experienced orthopedic specialists in a random order using a grading system for LDD assessment. Using a comprehensive grading system for LDD, discs were classified into 5 grades, as described by Pfirrman et al. This system uses characteristics of disc structure, distinction between the nucleus and annulus, MRI signal intensity, and intervertebral disc height for grading, and has been accepted as a standardized and reliable evaluation tool for assessment of MRI disc morphology.
