Interspinous ligament steroid injections for the management of Baastrup's disease: a case report

Mitra R, Ghazi U, Kirpalani D, Cheng I. Interspinous ligament steroid injections for the management of Baastrup's disease: a case report. Baastrup's disease has been identified as a source of axial low back pain. There has been debate as to the etiology of pain in patients with Baastrup's disease. It has been theorized that the pain may originate from degenerative disk disease and spinal stenosis associated with the disease, whereas some have identified the neoarthrosis between joints and accompanying reactive eburnation as the source of pain. We present a simple case report of an 89-year-old woman with symptomatic Baastrup's disease. The patient underwent a fluoroscopically guided interspinous process injection of 20mg of triamcinolone acetate with local anesthetic. The patient remained pain free for 3 months. The neoarthrosis in Baastrup's disease may be the primary pain generator in cases of Baastrup's disease without significant central canal stenosis.
