Randomized Controlled Trial
Lumbar total disc replacement: predictors for long-term outcome.
We aimed to identify patient characteristics associated with favourable long-term outcomes after lumbar total disc replacement (TDR). ⋯ Patients with Modic changes prior to the TDR surgery were more likely to report a clinically important functional improvement at long-term follow-up. Comorbidity, low level of education, long-term sick leave and high ODI score at baseline were associated with unemployment at long-term follow-up.
