Abstract
In this retrospective study 27 patients who had undergone revision discectomies for recurrent lumbar disc herniations were surveyed to assess their clinical outcomes. The patients chosen for the study were compared to a control group of 30 matched patients who had undergone only a primary discectomy. The spine module of the MODEMS® outcome instrument was used to evaluate the patients’ satisfaction, their pain and functional ability following discectomy, as well as their quality of life. All patients were also asked whether they were improved or worsened with surgery. Those undergoing revision surgery were asked whether the improvement following the second surgery was more or less than the improvement following the first surgery. Differences in residual numbness/tingling in the leg and/or the foot as well as in frequency of back and/or buttock pain were identified. Nevertheless improvement due to the repeat discectomy was not statistically different from those who underwent just the primary operation. Based upon patient derived outcome data with a validated instrument, revision discectomy is as efficacious as primary discectomy in selected patients.
