dc.description.abstractSTUDY DESIGN: This is a retrospective control study.
OBJECTIVE: We aimed to determine whether preexisting cervical disk degeneration is a prognostic factor in Whiplash-associated disorder (WAD).
SUMMARY OF BACKGROUND DATA: WAD is a common injury of traffic accident and has a broad range of prognoses. Although numerous studies have investigated prognostic factors in WAD, few have evaluated the effect of preexisting disk degeneration.
MATERIALS AND METHODS: This study involved 45 consecutive patients with grade I or II WAD having advanced disk degeneration (at least 1 disk of Miyazaki grade>/=III on magnetic resonance imaging) and a control cohort of 52 patients with no or mild disk degeneration (all disks having Miyazaki gradesRESULTS: There were no differences between the 2 groups regarding demographics and baseline outcome parameters (all P>0.05). There were also no differences in improvement in visual analog scale for neck pain, neck disability index, SF-36 physical composite score, or SF-36 mental composite score between the 2 groups (all P>0.05) for each visit. The number of claim closures was significantly lower among patients with advanced degeneration than among controls at 6-month and 1-year follow-ups (P=0.004 and 0.006, respectively).
CONCLUSIONS: In the present study, the clinical presentation and prognosis of WAD were not affected by preexisting disk degeneration. However, claim closure was delayed in patients with preexisting disk degeneration. These results suggest that misunderstanding of disk degeneration on magnetic resonance imaging may create persistent illness and lead to continued compensation in WAD.
