Abstract
ObjectiveTo evaluate the predictive value of Modic typeII changes on nuclear magnetic resonance (NMR) prior to intervention by discectomy for lumbar disc herniation in patients with radicular symptoms. Material and methodRetrospective descriptive study of 190 patients (58.2% men and 41.8% women) with a mean age of 43.5 years, treated between December 2005 and January 2013.They were divided into group 1, single disc herniation (n=85), and group 2, with disc herniation and changes Modic typeII (n=80).Variables studied: weight, height, handedness, level of injury, previous neurological deficit, postoperative complications, persistent pain and need for posterior lumbar fusion, with a mean of 67 months (group 1: 68.1; group 2: 66.8). ResultsIn group 1 there were four hernia recurrences requiring revision surgery and six patients needed lumbar fusion. In group 2, four recurrences were also revised and eight cases requiring arthrodesis were observed.No statistically significant differences were found when comparing the occurrence of relapse (p=.903), the need for subsequent fusion (p=.572) or in the remaining variables. DiscussionThe data obtained and the characteristics of our study, we cannot say that Modic typeII changes were a predictive sign of the result of lumbar discectomy in our study population.
