Bone Scanning in Lumbar Disc Herniation

Abstract
99mTc methylene diphosphate was used for whole body scanning and linear multiplane tomoscanning in 10 patients with typical clinical symptoms of prolapsed disc in order to investigate whether there would be an increased focal accumulation corresponding to the bone structures adjacent to the affected disc. The diagnosis of a prolapsed disc was confirmed by amipaque myelography, carried out in 9 patients, and finally verified at operation. In none of the 10 cases could accumulation of radioactivity in the bony structures of the affected lumbar segment be demonstrated. This method was not adopted for the diagnosis of prolapsed lumbar discs. 99mTc methylene diphosphate scintillography was useful in the differential diagnosis of ankylosing spondylitis and discitis.
