Resumen

MELUZZI, Alexandre et al. Prognostic factors associated with surgical treatment of cervical spondylotic myeloradiculopathy. Coluna/Columna [online]. 2012, vol.11, n.1, pp.52-62. ISSN 1808-1851.  http://dx.doi.org/10.1590/S1808-18512012000100010.

OBJECTIVE: Identify the individual, social, environmental clinical factors and also imaging studies which correlate to the final result of neurological improvement in patients undergoing surgical treatment of cervical spondylotic myelopathy. METHODS: The clinical assessment was quantified by the deficit in JOA scale. We analyzed 200 cases of cervical myeloradiculopathy surgically treated in HC-FMUSP, from January 1993 to January 2007. The mean follow-up was 6 years and 8 months. The analysis was based on radiological criteria of instability by White and Kellgren scale. RESULTS: 80%  had improved, 14% stabilized and 6% had worsened. The neurological deterioration was not associated with any clinical, environmental or imaging factor. The neurological improvement was directly proportional to the lower age at surgery, absence of co-morbidity, Hoffman sign, muscular atrophy, spinal cord hyperintensity on MRI, the shortest period of preoperative evolution, better preoperative neurological status and was inversely proportional to the AP diameter of the spinal canal and to multiple cord compressions. An association with smoking was observed. Over 70 years of age, evolution superior to 24 months, muscle atrophy, JOA score equal to or less than seven points and AP canal diameter less than or equal to 6mm were not associated with improvement.
