Objectives: Osteitis pubis is a noninfectious painfulinflammatory disorder of the symphysis pubis. Etiologicfactors are numerous, the most common are: osseousextension of adductor enthesis due to sport overuse,irritation after urological and abdominal procedures, andsystemic inflammatory disorders in particular spondylarthropathies.Many cases are idiopathic. The symptomsconsist of regional chronic mechanical and sometimenocturnal pain. Diagnosis is usually confirmed by eitherbone scintigraphy or by MRI. There are no standardtreatments but conservative approaches including rest andNSAIDS are generally recommended. In 2001, a goodclinical and radiological response of three refractory caseswith 3-6 monthly perfusions of pamidronate was reported(1). Ibandronate is a much more powerful and long-lastingbisphosphonate than pamidronate, and has not yet beenreported in literature to our knowledge in this indication.Materials/Methods: We present two cases of idiopathicorigin: one woman (63 years old) and one man (36 yearsold).The symptoms were present >3 months in the firstpatient and 1 year in the second. The diagnosis wasconfirmed by MRI which showed bone edema on bothsizes of symphysis and in the second case bony erosionsadjacent to the joint were seen. Both cases failed to respondto conservative measures. Both patients received one singledirect iv Injection of 3 mg of Ibandronate.Results: The injections resulted in a rapid (within a fewdays) resolution of pain that lasted more than 6 months inboth patients. No side effects were observed. In the firstcase, an isotope bone scan performed 4 months after theinjection showed no residual uptake. The second patienthad a repeated MRI after 6 months. It demonstrated anattenuation of bone edema compared to the first MRI.Conclusions: IV Ibandronate may constitute a safe andeffective treatment option for patients with refractoryosteitis pubis.Reference: 1: Maksymowych WP, Aaron SL, Russell AS, JRheumatol 28:2754, 2001.Disclosure of Interest: None declared.
