Factores pronósticos del resultado de la quimionucleosis

Successful results of chemonucleolysis depend specially on astrict patient selection. In this paper the influence of different preoperative,clinical and radiologic factors on the results two years after chemonucleolysis,i s reviewed through the statistical analysis of the cases.The authors have observed the isolated or persistent low back pain(rather than sciatica), and being an autonomous worker as poor prognosisfactors in their environment. Size and site, either midline or lateral, of thedisc herniation did not influence the results of chemonucleolysis with statisticalsignificance; nor did the number of discs explored or injected, neither thepresence of radiologic or tomodensitometric findings associated with symptomaticdisc herniation.
