Abstract: Suri P, Rainville J, Hunter DJ, Li L, Katz JN. Recurrence of radicular pain or back pain after nonsurgical treatment of symptomatic lumbar disk herniation. Objectives: To determine recurrence rates of lower-extremity radicular pain after nonsurgical treatment of acute symptomatic lumbar disk herniation (LDH), and to identify predictors of recurrence. Design: Prospective inception cohort. Setting: Outpatient spine clinic. Participants: Patients (N=79) reporting resolution of radicular pain after magnetic resonance imaging confirmation of LDH. Interventions: Individualized nonsurgical treatment tailored to the patient. All patients received education, but other treatments varied depending on the individual. Main Outcome Measures: Resolution of radicular pain was defined as a pain-free period of ≥1 month. Patients who reported resolution of radicular pain within 1 year after seeking care for acute LDH were asked whether pain had recurred at 1 year after seeking care and were also reassessed 1 year after the time of resolution of radicular pain and 2 years after seeking care. Patients reported on recurrence and the date of recurrence, if any. We evaluated the 1-year incidence of recurrence, using Kaplan-Meier survival plots. We examined predictors of recurrence using bivariate and multivariate Cox proportional hazards models. We examined the secondary outcome of back pain recurrence using identical methods. Results: Twenty-five percent (95% confidence interval [CI], 15–35) of individuals with resolution of radicular pain for at least 1 month reported subsequent recurrence of pain within 1 year after resolution. The only factor independently associated with radicular pain recurrence was the number of months prior to resolution of pain (hazard ratio per month=1.24; 95% CI, 1.13–1.37; P<.001). The 1-year incidence of back pain recurrence was 43% (95% CI, 30–56), and older age decreased the hazard of recurrence. Conclusions: Recurrence of radicular pain is relatively common after nonsurgical treatment of LDH and is predicted by longer time to initial resolution of pain. [Copyright &y& Elsevier] |
