STUDY DESIGN Descriptive cross-sectional study. PURPOSE To determine the prevalence of lumbar spondylolysis and spondylolisthesis in a general adult population unrelated to lower back pain as evaluated by multidetector computed tomography. OVERVIEW OF LITERATURE There is a significant paucity of information related to the prevalence of spondylolysis and spondylolisthesis and its degenerativ...

BACKGROUND CONTEXT Lumbar degenerative spondylolisthesis (LDS) is often diagnosed by conventional supine magnetic resonance imaging (MRI). Numerous studies have shown, however, that the degree of spondylolisthesis can be reduced or disappears when the patient is supine as compared with standing lateral and flexion-extension (SLFE) radiographs. PURPOSE To compare the sensitivity of supine MRI ...

BACKGROUND To evaluate the effect of spondylolisthesis on lumbar lordosis on the OSI (Jackson; Orthopaedic Systems Inc.) frame. Restoration of lumbar lordosis is important for maintaining sagittal balance. Physiologic lumbar lordosis has to be gained by intraoperative prone positioning with a hip extension and posterior instrumentation technique. There are some debates about changing lumbar lor...

Unstable degenerative spondylolisthesis of the cervical spine is very rare. Slip usually occurs at the C3 on C4 or C4 on C5 levels, immediately above a stiff lower cervical spine. There are two clinical patterns: that with neurological involvement causing cervicobrachial pain or myelopathy and that with neck pain alone. The diagnosis can be made by flexion/extension radiography. All of our eigh...

OBJECTIVE To investigate clinical-radiological features of cervical myelopathy due to degenerative spondylolisthesis (DSL). METHODS A total of 448 patients were operated for cervical myelopathy at Nishitaga National Hospital between 2000 and 2003. Of these patients, DSL at the symptomatic disc level was observed in 22 (4.9%) patients. Clinical features were investigated by medical records, an...

Although chronic low back pain is one of the most common causes of disability, it is rarely reported concomitant with testicular pain. The latter is often ignored because many clinicians are not aware of the referred testicular pain caused by degenerative lumbar disease. Awareness of the related innervations between the lumbar spine and the testis is the key in understanding the connection betw...

Low back pain and sciatica are highly debilitating conditions affecting all socioeconomic groups at an increasingly early age. They caused by different often concomitant spinal disorders: disc or facet joint disease, spondylolisthesis (with without listhesis), vertebral body interapophyseal arthrosis, stenosis, radicular synovial cysts and, more rarely, infections primary metastatic cancer.Trea...

A 35-year-old male who had been receiving conservative treatment for L4 isthmic spondylolisthesis suffered from pyogenic spondylodiscitis in the degenerative L4/L5 intervertebral disc space, which could be identified by comparison with previous images. Symptoms improved with conservative antibiotic treatment. Neovascularization may occur in the annulus fibrosus of a degenerative intervertebral ...
