Intradural extra-arachnoid lumbar disc herniation is a rare disease. Few MRI findings have been reported. We experienced an intradural extra-arachnoid lumbar disc herniation. We reviewed the preoperative MRI findings. Lumbar spine T2-weighted sagittal MRI showed that one line of the ventral dura was divided into two by a disc herniation. We speculated that the two lines comprised the dura and a...

Recent years, various percutaneous procedures including cervical nucleoplasty have been developed for disc decompressions to relieve radicular pains caused by disc herniations. We report the application of percutaneous cervical nucleoplasty (PCN) by using the navigable disc decompression device in two patients of cervical herniated intervertebral discs (HIVD). A 38-year-old female diagnosed wit...

INTRODUCTION Disc herniation is a complex spinal disorder associated with disability and high healthcare cost. Lumbar disc herniation is strongly associated with disc degeneration. Candidate genes of the aggrecan metabolic pathway may associate with the severity of lumbar disc herniation. OBJECTIVES This study evaluated the association of single nucleotide variants (SNVs) of the candidate gen...

Pathogenesis Hoerlein determined that intervertebral disc disease (IVDD) accounted for 2.02% of all diseases diagnosed in dogs (Hoerlein 1952). Incidence of IVDD peaks at 4 to 6 years of age in chondrodystrophic breeds and at 6 to 8 years in nonchondrodystrophic breeds (Priester 1976). The Dachshund had the highest frequency followed in succession by the Pekingese, Welsh corgi, Beagle, Lhasa Ap...

STUDY DESIGN Lumbar peripheral nerves were examined to determine whether they were responsive to electrical stimulation of the ventral portion of the lumbar disc in anesthetized rats. OBJECTIVES To confirm by electrophysiologic means the neural correspondence between the ventral portion of the lumbar disc and the groin. SUMMARY OF BACKGROUND DATA Patients with a degenerated lumbar disc occa...

Spontaneous disappearance of a herniated lumbar disc is known to occur. This case study describes a 45-year-old patient whose symptoms of lumbar radiculopathy resolved and follow-up imaging showed complete disappearance of the disc prolapse. This phenomenon strengthens the role of conservative treatment in the management of lumbar disc protrusions.

Discal cyst is an intraspinal cyst with a distinct communication with the corresponding intervertebral disc. It is a rare condition and could present with radiculopathy similar to that caused by lumbar disc herniation. We present a patient with a large discal cyst in the ventrolateral epidural space of the 5(th) lumbar vertebral (L5) level that communicated with the adjacent 4(th) lumbar and 5(...

Low back pain is common during pregnancy. However, the prevalence of symtomatic lumbar disc herniation is rare, and cauda equina syndrome due to disc herniation during pregnancy is even rarer. We report a rare case of lumbar disc herniation causing cauda equina syndrome during third trimester of pregnancy which successfully treated by endoscopic discectomy. This case shows that endoscopic disce...

Although lumbar discectomy is an effective treatment for lumbar disc herniation, complications exist, including postoperative disc height loss, facet joint degeneration, and recurrent disc herniation. To solve these problems, annular closure devices have been utilized in other countries, producing satisfactory results, but there has been no report of annular closure device use in our country. H...
