BACKGROUND Degenerative changes of the cervical spine are an inevitable response to certain occupational status and aging processes. Compression of cervical nerve roots may result from disc degeneration, disc herniation or intervertebral foraminal stenosis. The precise and detailed anatomical knowledge of the intervertebral foramen of the cervical spine is essential for the diagnosis and manage...

The intervertebral disc is submitted to complex loading during its normal daily activities which are responsible for variations of the hydrostatic pressure in its structure. Thus, the determination of the magnitude of failure hydrostatic pressure is essential as a potential for the evaluation of the mechanisms that promote the weakening and the disruption of the annular fibers, commonly linked ...

Background and Importance: Intradural lumbar disc herniation is a rare and uncommon presentation of lumbar disc herniation. It signifies a challenge for diagnostic and therapeutic scheme, and is associated with a greater incidence of cauda equina syndrome at presentation. Case Presentation: We describe two cases of intradural disc herniation who underwent surgery in Senegal review literat...

Background: lumbar disc degeneration is a multifactorial degenerative disease which is affected by genetic inheritance and environmental factors. Type XI collagen is important for organization of the extracellular matrix and cartilage collagen construction. Rs1676486 is a SNP that causes the conversion of C-T, resulting in a change in the expression of the collagen 11 alpha chain. The T allele ...

The prevalence of intervertebral disc herniation (IDH) of the thoracic spine is rare compared to the cervical or lumbar spine. In particular, IDH of the upper thoracic spine is extremely rare. We report the case of T1-2 IDH and its treatment, with a literature review. A 37-year-old male patient visited our hospital due to radiating pain at the left upper extremity and weakness of grip power. In...

Intervertebral disc (IVD) degeneration is an underlying pathological process which leads to lower back pain (1). Whilst initial weakening of IVDs may be asymptomatic, subsequent disc herniation can cause spinal stenosis and segmental instability (2). Conservative or surgical management can alleviate clinical symptoms, but may be unable to prevent continued degeneration. As degenerative disc dis...

background: a large proportion of patients presenting with lumbar disc disease are opium addicts in our region. it was, therefore, hypothesized that morphine might affect the intervertebral disc. we investigated the histological findings of morphine dependency on intervertebral discs in rat.   methods: forty nmri adult male rats (230-250 g) placed on ordinary diet and received aqueous solution ...

Little information is at hand on the diagnostic values of the clinical symptoms and signs in the level diagnosis of patients with lower lumbar disc herniation.  We examined one hundred and thirty nine consecutive candidates for lower lumbar discectomy.  Monoradicular pain with signs attributed to the fifth lumbar and first sacral root dysfunctions were evaluated independently in each patient.  ...

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...
