The authors report 2 cases of nerve root herniation after discectomy of a large lumbar disc herniation caused by an unrecognized dural tear. Patients complained of the abrupt onset of radiating pain after lumbar discectomy. Magnetic resonance imaging showed cerebrospinal fluid signal in the disc space and nerve root displacement into the disc space. Symptoms improved after the herniated nerve r...

BACKGROUND CONTEXT Gadolinium-enhanced magnetic resonance imaging (Gd-MRI) is often performed in the evaluation of patients with persistent sciatica after lumbar disc surgery. However, correlation between enhancement and clinical findings is debated, and limited data are available regarding the reliability of enhancement findings. PURPOSE To evaluate the reliability of Gd-MRI findings and the...

background and importance: disk sequestration can be defined as a herniated disk with perforation of the fibrous ring (or outermost annulus fibrosus) and posterior longitudinal ligament with migration of the disk fragment to the epidural space. even after the introduction of high-resolution magnetic resonance imaging (mri), it is still frequently misinterpreted as neoplastic masses. unfortunate...

Adjacent level cervical disc disease and secondarily progressive disc space degeneration that develops years after previously successful anterior cervical fusion at one or more levels is a common, but potentially complex problem to manage. The patient is faced with the option of further open surgery which involves adding another level of disc removal with fusion, posterior decompression, and st...

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...

The records of 403 patients treated for herniated lumbar disc disease were analysed in a retrospective observational study in order to verify how three outcome measures, i.e., satisfaction with the outcome of surgery, the degree of return to activities of daily living including work (ADL), and duration of interruption of ADL, may be influenced by clinical variables. Age, type of disc herniation...

BACKGROUND Herniated intervertebral disc disease (HIVD) is a common cause of lower back and leg pain. Percutaneous endoscopic lumbar discectomy (PELD) is indicated when non-surgical treatments such as medication and interventions are intractable. Ruptured discs and loose fragments inside discs are removed during PELD. Nerve root decompression is usually assessed by visualizing the free movement...

Introduction : Condoliase injection for lumbar disc herniation is less invasive than surgical treatment and has been widely used in recent years. We encountered a case which herniated worsened after with condoliase (Hernicore®) injection. Thereafter discectomy was performed. also report the pathology of removed immediately

BACKGROUND Magnetic Resonance Imaging (MRI) is considered the mainstay imaging investigation in patients suspected of lumbar disc herniations. Both imaging and clinical findings determine the final decision of surgery. The objective of this study was to assess MRI observer variation in patients with sciatica who are potential candidates for lumbar disc surgery. METHODS Patients for this study...
