Objective The lumbar lesion in rheumatoid arthritis (RA) have been paid less attention, but some previous studies demonstrated the high prevalence of lumbar spondylolisthesis and lumbar scoliosis. The lumbar lesion accompanied with RA is often difficult to treat, and it is important to know the characteristics of lumbar lesion in RA patients. The purpose of this study is to clarify the features...

Lumbar spinal stenosis refers to a diversity of conditions that decrease the total area of the spinal canal, lateral recesses, or neural foramina. Lumbar stenosis is a common disorder that may be present in isolation, with or without associated disk bulge or herniation, or can be associated with degenerative spondylolisthesis or scoliosis. Symptomatic lumbar spinal stenosis is characterized by ...

BACKGROUND Spinal fusion with pedicle screw fixation represents the gold standard for lumbar degenerative disc disease with instability. Although it is an established technique, it is nevertheless an invasive intervention with high complication rates. Therefore, minimally invasive approaches have been developed, the medialized bilateral screw pedicel fixation (mPACT) being one of them. The stud...

We aimed to study correlation between bone mineral density (BMD) and facet joint orientation in normal, osteopenic and osteoporotic patients. The correlation between more sagittally oriented facet joint and facet joint osteoarthritis and spondylolisthesis was described previously. However, the correlation between facet joint orientation and its possible correlation with BMD measurements has not...

OBJECTIVE The purpose of this study was to evaluate the differences in sagittal spinopelvic alignment between lumbar degenerative spondylolisthesis (DSPL) and degenerative spinal stenosis (DSS). METHODS Seventy patients with DSPL and 72 patients with DSS who were treated with lumbar interbody fusion surgery were included in this study. The following spinopelvic parameters were measured on who...

Degenerative disc disease and spinal stenosis lead to various symptoms. Degeneration of facet joints is added to this degenerative process with aging.Seventy-four patients who were admitted to the Spinal Column Outpatient Clinic of the Neurosurgery Department with a diagnosis of degenerative narrow spinal canal and lumbar spondylolisthesis between 2011 and 2013 and who underwent surgery were in...

STUDY DESIGN A questionnaire survey. OBJECTIVE To report the current use of recombinant human bone morphogenetic protein-2 (rhBMP-2) in lumbar fusion procedures for the treatment of degenerative spondylolisthesis (DS), and identify associated factors including fusion technique, surgeon location, surgeon specialty, or surgeon practice model. SUMMARY OF BACKGROUND DATA The prevalence of rhBMP...

Generally, bilateral pedicle screw fixation after Minimal Invasive (MIS) TLIF is accepted as a standard procedure for treating symptomatic spinal pathologies, such as degenerative spinal stenosis, spondylolisthesis, recurrent disc herniation, postlaminectomy instability, and deformity (10). Some authors have recently demonstrated that unilateral pedicle screw fixation is as effective for spinal...
