Abstract
ESCARPANTER BULIES, JULIO C; CEBALLOS MESA, ALFREDO and RODRIGUEZ MESA, NELSON. Role of the intervertebral disc in the etiology of low back pain. Rev Cubana Ortop Traumatol [online]. 1997, vol.11, n.1-2, pp. 61-66. ISSN 1561-3100.
The study of 33 patients with diaphyseal pseudoarthrosis, who underwent a bone scintigraphy using Tc 99m MDP as radiotracer is reported. It is determined the focal capture according to an evaluative pattern previously determined to define the radiopharmaceutical's capture degree, which is interpreted as the translation of the metabolic activity of the focal lesion, and it is found a fissure with central aphotony that indicates the presence of a synovial pseudoarthrosis. It is stressed in the conclusions the high diagnostic effectiveness in the detection of synovial pseudoarthrosis, as well as the determination of the focal viability, the lack of relation existing for its estimate between the scintigraphic study and the simple radiographical study, and the advantage to supposse the presence of focal necrosis with the results of the scintigraphy.
