Primary Outcome Measures:
  • back pain assessed on a100mm VAS [ Time Frame: at 3 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • - Functional status using EIFEL, Dallas, FABQ, MacTar, and MCII/PASS questionnaires [ Time Frame: at 6 weeks, 3 months, and 6 months ] [ Designated as safety issue: Yes ]
  • Back stiffness assessed by Schober's test and finger-to-floor distance [ Time Frame: at 6 weeks, 3 months, and 6 months ] [ Designated as safety issue: Yes ]
  • Inflammatory pain pattern [ Time Frame: at 6 weeks, 3 months, and 6 months ] [ Designated as safety issue: Yes ]
    Inflammatory pain pattern: number of nightly awakenings, as well as duration and intensity of morning stiffness on a 100mm VAS

  • assess the efficacy of a rigid back brace in treating back pain [ Time Frame: at 6 weeks, 3 months, and 6 months ] [ Designated as safety issue: Yes ]
    In case of failure to reduce the pain with pamidronate at 3 months: assess the efficacy of a rigid back brace in treating back pain

  • Tolerance based on the number and types of side-effects [ Time Frame: at 6 weeks, 3 months, and 6 months ] [ Designated as safety issue: Yes ]

Detailed Description:

Erosive degenerative disk disease, also known as Modic type 1 changes, is usually characterized by low back pain, with an inflammatory pain pattern, as seen in spondylarthropathies. Intravenous pamidronate has proven effective in patients with ankylosing spondylitis, and in painful bone diseases in general. We therefore hypothesized that pamidronate would be effective in treating back pain associated with Modic type 1 changes.

This study aimed to determine pamidronate's efficiency in reducing pain, with the primary outcome being a between-group difference of 30 points on a 100mm VAS at 3 months. Secondary outcomes are the improvement in functional status and the drug's tolerance. Primary and secondary outcome criteria will be assessed at each visit (inclusion, at 6 weeks, 3 months, and 6 months). If the primary goal is not attained, a rigid or semi-rigid back brace will be proposed to the patient, regardless of the treatment group.

In total, 48 patients will need to be recruited. These patients will be randomly assigned to one of the two groups, with each group comprising 24 patients: one group will be given pamidronate and the other placebo. Pamidronate will be administered at a dose of 90mg per day, 2 days in a row, and every patient, regardless of the treatment group, will be given paracetamol, in order to maintain blinding by preventing drug-induced fever.
