background: excessive lumbar vertebrae translation and rotation in sagittal plane has been attributed as an associated factor of lumbar segmental instability (lsi) and low back pain (lbp). reduction of these abnormalities improves back pain. the aim of this study was to investigate the effect of core stability exercise on the translation and rotation of lumbar vertebrae in sagittal plane in pat...

A review of the etiology, clinical, radiological, differential diagnosis and management goals of segmental instability is presented.

Lumbar spine instability develops as a result of a gradual degenerative process. Segmental instability causes chronic low back pain and decreases the quality of life of the patient. The deformity that develops secondary to lumbar instability is seen as coronal and sagittal imbalance. The diagnosis is made with the radiological and clinical findings. Surgery and stabilization is necessary for th...

STUDY DESIGN Retrospective chart review. PURPOSE To assess whether spontaneous reduction of spondylolisthesis, as seen on magnetic resonance imaging (MRI), is related to the degree of segmental instability and low back pain. OVERVIEW OF LITERATURE The flexion-extension radiographs obtained in the sagittal plane are frequently used when segmental instability of spondylolisthesis is evaluated...

STUDY DESIGN Retrospective cohort study. OBJECTIVE Lumbar segmental instability is a key factor determining whether decompression alone or decompression and fusion surgery is required to treat lumbar spinal stenosis (LSS). Some recent reports have suggested that facet joint effusion is correlated with spinal segmental instability. The aim of this study is to report the effect of facet effusio...

According to the American Academy of Orthopaedic Surgeons, instability was defined as an abnormal response to applied loads, characterized by movement in the motion segment beyond normal constraints in 1989. Segmental instability has been defined as occurring in patients with low back problems and whose clinical status is unstable, with symptoms fluctuating between mild and severe symptoms in r...

Surgery of lumbar disc herniation is still a problem since Mixter and Barr. Main trouble is dissatisfaction after the operation. Today there is a debate on surgical or conservative treatment despite spending great effort to provide patients with satisfaction. The main problem is segmental instability, and the minimally invasive approach via microscope or endoscope is not necessarily appropriate...
