BACKGROUND Treatment of symptomatic lumbar disc herniation with Modic type I endplate changes is complex and challenging, requiring systemic and local therapies which include conservative therapy, epidural infiltrations, percutaneous therapeutic techniques, and surgical options. The clinical management of symptomatic lumbar disc herniation involving Modic type I endplate changes is uniquely cha...

Symptomatic pneumocephalus is frequently seen after traumatic fracture of the skull base bone. However, it has rarely been reported after spinal surgery and its mechanism has not been fully explained. In this paper, we present a 30 year old male patient who had lumbar discectomy due to a symptomatic midline lumbar disc herniation. He had developed symptomatic pneumocephalus after the lumbar dis...

OBJECTIVE To explore factors predicting failure of conservative treatment in lumbar-disc herniation. BACKGROUND Sciatica due to lumbar-disc herniation is a common complaint of spine patients. Even though the natural course is favorable, surgery is necessary in at least 10% of cases. Current trends show surgery to be more cost-effective than prolonged conservative care. However; there is limit...

This study was to evaluate the effect of stress on the intervertebral disc and facet joint after implantation of device for intervertebral assisted motion (DIAM). Nine fresh human lumbar (L1-L5) cadavers were studied. The stress on L3-4, adjacent intervertebral disc and facet joints was measured in four groups. The cadavers in Group 1 were measured without special treatment; the lumbar discecto...

It has been previously suggested in the literature that with aging, degenerative changes as well as disc herniation start at the lower lumbar segments, with higher disc involvement observed in an ascending fashion in older age groups. We conducted a study to investigate this correlation between age and level of disc herniation, and to associate it with the magnitude of the Lumbar Lordotic Angle...

AIM Comparison of long-term preoperative and postoperative clinical and radiological results for patients diagnosed with degenerative disc disease that underwent posterior dynamic stabilization. Lumbar disc degeneration is caused by a variety of factors. Disruptions in the vertebral endplate result in defects in disc nutrition and, thus, disc degeneration. The aims of dynamic stabilization are ...

Background Patients with lumbar disc disease may present with low back pain, pain that radiates down to the lower extremity (radiculopathy), and leg pain that increases with ambulation (neurogenic claudication). Patients may first undergo diagnostic studies (magnetic resonance imaging, computed tomographic examinations) to determine whether there is any significant nerve root or thecal sac comp...

BACKGROUND The intervertebral disc has been implicated as a major cause of chronic lumbar spinal pain based on clinical, basic science, and epidemiological research. There is, however, a lack of consensus regarding the diagnosis and treatment of intervertebral disc disorders. Based on controlled evaluations, lumbar intervertebral discs have been shown to be the source of chronic back pain witho...

OBJECTIVE To analyse inter-observer variation between a neuroradiologist and neurosurgeon in the MRI diagnosis of lumbar nerve root compression. Although lumbar MFI is primarily analyzed and reported by a radiologist, neurosurgeons often analyse it independently as they have sufficient clinical background as well as radiological expertise to diagnose most spinal pathologies on Magnetic Resonanc...
