Prospective Evaluation of Correlations Between Discomanometry and MR Imaging Data: Role in the Management of Disc Disease — Preliminary Results
In the past, percutaneous nucleotomy (PN) indications did not seem to have been clearly defined and its success rate, commonly of 75% –80%, draws near to chemonucleolysis (CN) results published in the literature. However, in recent years, more accurate definition of CN indications has given rise to significantly improved CN results and a success rate of 95%, with respect to certain discographic data . In the same way, a CN success rate of more than 98% can be obtained with respect to specific discomanometric data . Discomanometry (DMM) is a physical investigation of the disc which consists of evaluation of its compliance status. Its diagnostic value has been demonstrated [1, 2], permitting recognition of leaking from “non-leaking” discs, and assessment and quantification of the degree of disc degeneration in terms of discal pressure level and volume of fluid tolerated by the disc. Its predictive value is based on significant correlation between its data and CN results . It follows therefrom that, as for CN, DMM had to be performed before PN procedure. Consequently, PN results had to be assessed in accordance with the data of DMM.
