Lumbar microdiscectomy: a historical perspective and current technical considerations

Abstract

<jats:p>A historical review is presented of the original descriptions of lumbar discectomy, focusing on the evolution toward a less invasive surgical approach following the introduction of the operating microscope. From the initial work in Europe by Yaşargil and Caspar to the popularization of microdiscectomy by Williams and Wilson in the United States, this procedure has successfully reduced operative time, surgical morbidity, and incision size while allowing patients to return to work faster. Emphasis is placed on the importance of a careful preoperative clinical and radiographic evaluation by identifying factors that may help in the prediction of a successful surgical outcome. A modification of the lumbar microdiscectomy technique is described including patient positioning in the lateral position as well as minimal disc space and nerve root manipulation. In their experience performing more than 3000 microdiscectomies, the authors have produced good-to-excellent clinical results in nearly 90% of patients, with the majority returning to work within 1 month. The complication rate of dural tears, discitis, or root injury has been less than 2%, with a reoperation rate of 5%. The authors believe that lumbar microdiscectomy remains the gold standard with which all other discectomy techniques must be compared.</jats:p>

“…11 Notably, the rate of re-herniation is nearly 20%, often occurring at the same disc location. 12 In all of these instances, the limited vascularity and the hypocellularity of these tissues in the adult engender only limited endogenous repair processes. Indeed, this repair does not restore normal tissue structure and function, and the once highly ordered tissue is instead replaced by a disorganized scar, that is, mechanically inferior and prone to re-injury.…”

How to predict return to work after lumbar discectomy: answers from the NeuroPoint-SD registry

“…2,8 Despite the common prevalence of lumbar radiculopathy and surgical discectomy, little is known regarding the factors that contribute to the likelihood of a patient returning to employment postoperatively. Certainly, this is information useful for both patients and providers to understand.…”
