Lumbar discectomy is a successful treatment for symptomatic lumbar disc herniation, but at least 8 years of follow-up have reported the incidence of recurrent lumbar disc herniation of 38%, total reoperation rate of 15%, and reoperation rate for recurrent lumbar disc herniation of 9.1% [1]. In particular, recurrent lumbar disc herniation, which is defined as the presence of herniated disc material at the same level as previously operated upon in patients who experienced a pain-free phase for more than 6 months, is the known most common cause of surgical failure of lumbar discectomy.

摘要

Lumbar discectomy is a successful treatment for symptomatic lumbar disc herniation, but at least 8 years of follow-up have reported the incidence of recurrent lumbar disc herniation of 38%, total reoperation rate of 15%, and reoperation rate for recurrent lumbar disc herniation of 9.1% [1]. In particular, recurrent lumbar disc herniation, which is defined as the presence of herniated disc material at the same level as previously operated upon in patients who experienced a pain-free phase for more than 6 months, is the known most common cause of surgical failure of lumbar discectomy.
