A prospective, cohort evaluation of 262 consecutive patients who underwent transforaminal endoscopic excision for recurrent lumbar disc herniation, after previous discectomy.
To review complications and results of the endoscopic transforaminal discectomy (ETD) for recurrent herniated disc with a 2-year follow-up.
Summary of Background Data
Recurrent herniation is a signiﬁcant problem, as scar formation and progressive disc degeneration may lead to increased morbidity after traditional posterior reoperation. The studies published until now on recurrent disc herniation concern various operative techniques, mostly the lumbar microdiscectomy, which is still seen as the standard. The advantage of ETD could be that there is no need to go through the old scar tissue and the procedure can be performed in local anesthesia. The disadvantage may be a long learning curve for the surgeon.
