OBJECTIVES: To determine whether older adults (aged ≥60) experience less improvement in disability and pain with nonsurgical treatment of lumbar disk herniation (LDH) than younger adults (<60).
DESIGN: Prospective longitudinal comparative cohort study.
SETTING: Outpatient specialty spine clinic.
PARTICIPANTS: One hundred thirty-three consecutive patients with radicular pain and magnetic resonance–confirmed acute LDH (89 younger, 44 older).
INTERVENTION: Nonsurgical treatment customized for the individual patient.
MEASUREMENTS: Patient-reported disability on the Oswestry Disability Index (ODI), leg pain intensity, and back pain intensity were recorded at baseline and 1, 3, and 6 months. The primary outcome was the ODI change score at 6 months. Secondary longitudinal analyses examined rates of change over the follow-up period.
RESULTS: Older adults demonstrated improvements in ODI (range 0–100) and pain intensity (range 0–10) with nonsurgical treatment that were not significantly different from those seen in younger adults at 6 month follow-up, with or without adjustment for potential confounders. Adjusted mean improvement in older and younger adults were 31 versus 33 (P=.63) for ODI, 4.5 versus 4.5 (P=.99) for leg pain, and 2.4 versus 2.7 for back pain (P=.69). A greater amount of the total improvement in leg pain and back pain in older adults was noted in the first month of follow-up than in younger adults.
CONCLUSION: These preliminary findings suggest that the outcomes of LDH with nonsurgical treatment were not worse in older adults (≥60) than in younger adults (<60). Future research is warranted to examine nonsurgical treatment for LDH in older adults.
