Lumbar disk lesions in 47 cases were initially diagnosed using MRI investigation, then, after surgery, biological and histopathological aspects of intervertebral disks were revealed. Pieces from intervertebral disks were used for electron microscopy studies in order to determine collagen in the components of the intervertebral disk. The aim of the present study was to highlight the corresponden...

This study used data d...

Background: Lumber disc prolapse accounts for only 5% of all low back pain problems but is the most common cause of radiating nerve root pain which called sciatica. In the 20th century, techniques were developed to remove the herniated disc with minimal invasiveness, with these minimally invasive techniques; authors demonstrated decreased soft tissue manipulation, operative time, blood loss, an...

[Purpose] We compared the effectiveness of dry needling with a classical physiotherapy program in patients with chronic low-back pain caused by lumbar disc hernia (LHNP). [Subjects and Methods] In total, 34 subjects were allocated randomly to the study (n=18) and control groups (n=16). In the study group, dry needling was applied using acupuncture needles.

BACKGROUND Intervertebral disc disease is defined as a complex of structural changes in the aftermath of disorders of mutual elements, the structure of which form the discus intervertebralis and the spinal canal. The present work assessed pain in patients who were surgically treated due to spinal discopathy and analyzed factors that determine the condition. MATERIAL AND METHODS The research was...
