Abstract
The purpose of this study was to evaluate cervical intervertebral disc
degeneration in collegiate rugby players using magnetic resonance (MR)
imaging. Subjects were 43 collegiate rugby players, and were classified
into playing units (forward (FW); further classified into first row (1r),
second row (2r), and third row (3r), backs(BK)), past history of cervical
injury, or cervical alignment (lordosis, non lordosis). Sagittal MR images
of the cervical spine were taken at the level of the intervertebral disc
between C2 and T1. Cervical disc degeneration existed in 37.2% of all
players, and C5/6 level was recognized as the most degenerated disc level.
Chi-square tests showed that 3r group of playing units has significantly
related to degenerated cervical intervertebral disc at the level of C4/5, and
stronger relationship between non lordosis of cervical alignment and the
degeneration at C5/6 level. On the other hand, past history of cervical
injury was not significantly related to cervical intervertebral disc
degeneration. Further study such as a long-term or longitudinal research
design is required to identify risk factors of cervical disc degeneration.
