This study aimed to analyze the effect of patient positions on the lordosis and scoliosis of patients with degenerative lumbar scoliosis (DLS).Seventy-seven patients with DLS were retrospectively analyzed. We measured lordosis and Cobb's angle on preoperative upright x-rays and magnetic resonance imagings in supine position. The lordosis and scoliosis of surgical segments in intraoperative pron...

STUDY DESIGN Blinded test-retest design. OBJECTIVE To measure the intrarater and interrater reliability of the visual assessment of cervical and lumbar lordosis. SUMMARY OF BACKGROUND DATA Cervical and lumbar lordoses are frequently evaluated using visual assessment, but little attempt has previously been made to measure the reliability of visual assessment. METHODS Twenty-eight chiroprac...

Background and Objectives: Lumbar hyperlordosis is one of the main physical abnormalities that occur in the lumbopelvic region and affect the body movement system in daily life. This condition can also lead to chronic injuries and pain. The present study aimed to investigate the ability of the nine-test screening battery to predict the incidence of lumbar hyperlordosis in adolescent boys. Mate...

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...

 Abstract Objective: To present the changes in projected thoracic hypokyphosis and the behavior of lumbar lordosis within and below the fusion and to compare these changes between the Harrington rod (HR) and posterior multisegmented hook instrumentation. Methods: 178 patients with idiopathic scoliosis, who had undergone posterior spinal fusion with Harrington technique (106 patients) or multise...

The 2D shape of the lumbar spine in the sagittal plane can be determined from lordosis angles measured between the corresponding end-plates of the vertebral bodies or by using an active shape model (ASM) of the vertebral body outline. The ASM was previously shown to be a more efficient and reliable method, but its accuracy has not been assessed. The aim of this study was to determine the accura...

CONTEXT Isolated lumbar paraspinal muscle fatigue causes lower extremity and postural control deficits. OBJECTIVE To describe the change in body position during gait after fatiguing lumbar extension exercises in persons with recurrent episodes of low back pain compared with healthy controls. DESIGN Case-control study. SETTING Motion analysis laboratory. PATIENTS OR OTHER PARTICIPANTS Tw...

STUDY DESIGN Level 4 retrospective review. PURPOSE To compare the radiographic and clinical outcomes between posterior lumbar interbody fusion (PLIF) and lateral lumbar interbody fusion (LLIF) with posterior segmental spinal instrumentation (SSI) for degenerative lumbar spondylolisthesis. OVERVIEW OF LITERATURE Both PLIF and LLIF have been performed for degenerative spondylolisthesis with g...

OBJECTIVES To investigate the effects of backward adjustable thoracic support on spinal curvature and back muscle activation during wheelchair sitting. METHODS Twenty elderly people were recruited for this study. The backward adjustable thoracic support sitting posture was compared with the slumped, normal, and lumbar support sitting postures. Spinal curvatures (pelvic, lumbar, and thoracic a...

Objective. Posterior dynamic stabilization is an effective alternative to fusion in the treatment of chronic instability and degenerative disc disease (DDD) of the lumbar spine. This study was undertaken to investigate the efficacy of dynamic stabilization in chronic degenerative disc disease with Modic types 1 and 2. Modic types 1 and 2 degeneration can be painful. Classic approach in such cas...
