- Abstract
The correlation between the severity of cervical spinal canal stenosis(CCS)as evaluated by magnetic resonance imaging(MRI)and Pavlov's ratio on plain radiographs of the cervical spine was investigated in 520 American football(AF)and Rugby(RB)players who underwent both MRI and plane X-ray of the cervical spine between 1995 and 2003 as a medical check-up(MC). There were 7 athletes with no subarachnoid space in the cervical spinal canal on MRI, who were allocated lo the CCS group. Among the other 513 athletes who did not show any CCS on MRI, 50 athletes were selected randomly as the non-CCS group. Pavlov's ratio was significantly lower in the CCS group than in the non CCS group. In the CCS group, 12 vertebras had no subarachnoid space and their Pavlov's ratio was under 0.78. These results suggest that Pavlov's ratio less than 0.78 indicates CCS with no subarachnoid space on MRI.
