OBJECTIVE Recurrent lumbar disc herniation has been defined as disc herniation at the same level, regardless of ipsilateral or contralateral herniation, with a pain-free interval greater than 6 months. The aim of this study is to analyze outcomes and identify the potential risk factors for recurrent lumbar disc herniation. METHODS The authors retrospectively reviewed the cases of 178 patients...

BACKGROUND Cyclooxygenase inhibitor treatment is viewed increasingly critical because of safety considerations, and there are several open questions on their optimal use. METHODS In a randomized placebo-controlled study in 320 patients undergoing discectomy, we administered parecoxib 40 mg either perioperatively (before operation and after operation), after operation (first dose given in the ...

BACKGROUND CONTEXT Lumbar discectomies are common surgical interventions that treat radiculopathy by removing herniated and loose intervertebral disc (IVD) tissues. However, remaining IVD tissue can continue to degenerate resulting in long-term clinical problems. Little information is available on the effects of discectomy on IVD biology. Currently, no treatments exist that can suspend or rever...

BACKGROUND Since the descriptions by Mixter and Barr of surgical treatment for rupture of the intervertebral disc in 1934, open surgical procedures have become a common practice. Disc herniations are often classified as being contained or non-contained. The results of open surgical discectomy for contained disc herniation have been poor. Consequently, several less invasive techniques have been ...

Percutaneous disc surgery, also known as percutaneous discectomy (PD), for herniated nucleus pulposus (HNP) was introduced by Hijikata [1] in Japan. Indeed, as compared with traditional disc surgery such as love’s procedure, PD is minimally invasive since it can be performed under local anesthesia. However, Hijikata’s technique does not use a spinal endoscope; thus, its reliability for the remo...

abstract background : the purpose of this study is to evaluate anterior cervical discectomy. materials and methods : this retrospective study was conducted on 43 patients underwent surgery through standard smith-robison technique with fusion. postoperative follow-up period was 24 months. clinical assessment was done through odom criteria, neck disability index and vas for neck pain. results : a...

OBJECTIVE Percutaneous endoscopic transforaminal discectomy is often used as a minimally invasive procedure for lumbar disc herniation. However, a transforaminal approach posts limitations at the L5-S1 level owing to anatomic constraints, such as a high iliac crest or small intervertebral foramen and especially for migrated large intracanalicular disc herniations. We discuss the procedure and c...

BACKGROUND We sought to construct a general methodology for objectively quantifying the learning curve associated with any surgical technique and to determine the number of cases needed to achieve a success rate of 90% for the technique of transforaminal endoscopic lumbar discectomy. To our knowledge, no other studies have observed the learning curve of endoscopic lumbar discectomy by transfora...
