BACKGROUND We designed an easy posterolateral transforaminal endoscopic decompression technique, termed PTES, for radiculopathy secondary to lumbar disc herniation. The purpose of the study is to describe the technique of PTES and evaluate the efficacy and safety for treatment of lumbar disc herniation including primary herniation, reherniation, intracanal herniation, and extracanal herniation ...

Apoptosis plays pivotal role in the pathogenesis of degenerative disc diseases, which is the primary contributor to low back pain. Although the role of hydrogen sulfide (H2S) in cell apoptosis is well appreciated, the effects and mechanism that H2S regulates the program death of intervertebral disc cell are not yet elucidated. In this study, we utilized the nucleus pulposus (NP) from patients w...

OBJECTIVE To evaluate the usefulness of back pain questionnaires for lumbar disc screening among Korean young males. METHODS We carried out a survey for lumbar disc screening through back pain questionnaires among the volunteers with or without back pain. Three types of back pain questionnaire (Oswestry Low Back Pain Score, Aberdeen Low Back Pain Scale, and Acute Low Back Pain Screeing Questi...

BACKGROUND The overall rate of operations after recurrent lumbar disc herniation has been shown to be 3-11%. However, little is known about the rate of residives. Thus the aim of this study was to explore the cumulative rates of re-operations and especially residive disc herniations at the same side and level as the primary disc herniation after first lumbar disc herniation surgery and the fact...

In this study we present the efficacy of aspiration of disc material employing the Stryker Disc Dekompressor during percutaneous microdiscectomy for the treatment of chronic spinal and radicular pain due to contained lumber disc herniation and compare the short-term outcome in such patients with those who received lumber epidural injection. A total of 50 patients with chronic lumber discogenic ...

UNLABELLED The technique of percutaneous endoscopic lumbar discetomy (PELD) in the transforaminal approach has evolved over the years due to the advances in endoscopic photology and instrumentation and become the most popular technique for lumbar disc herniation. Although PELD offers many advantages, the indications of PELD are limited mostly to non-migrated or low-migrated disc herniation. It ...

Intradural disc herniation is found in only 0.3% of cases of disc herniation. The majority of these (>95%) are found in the lumbar region, with fewer than 5% occurring in the thoracic region [1,2]. While imaging occasionally raises suspicion of an intradural component to a herniated disc, the majority of cases are diagnosed intraoperatively [1-6]. We describe a case of an intradural thoracic di...

BACKGROUND The surgical treatment of sciatica with discectomy is ineffective in a sizable percentage of patients, and reherniation occurs after 5% to 15% of such procedures. The purpose of the present study was to determine if competence of the disc anulus and the type of herniation could be used to predict postoperative clinical outcomes following lumbar discectomy. METHODS A prospective obs...

The development in technology and informatics in the last decades enables integrated analysis of biomechanical and clinical data and facilitates the understanding of relations between human gait characteristic and different medical conditions of a patient. The aim of the study was to demonstrate the importance of gait temporospatial parameters analysis [opposite foot off, opposite foot contact,...

BACKGROUND Caudal epidural injection of local anesthetics with or without steroids is one of the most commonly used interventions in managing chronic low back and lower extremity pain. However, there has been a lack of well-designed randomized, controlled studies to determine the effectiveness of caudal epidural injections in various conditions - disc herniation and radiculitis, post-lumbar lam...
