Some radiological features of the lumbar spine of 84 patients with spastic diplegia were compared with 50 control subjects. The average age of the patients was 20.1 years (3 to 39). Spondylolysis of the fifth lumbar vertebra was found in 21%, four times more frequently than in normal subjects. No patient under nine years of age had spondylolysis and the frequency increased with age. The average...

Posture and flexibility were assessed in 34 athletes. Subjects were divided into two groups: (1) a noninjured group that did not have a history of hamstring strain injury within the previous 12 months; (2) an injured group that had a history of hamstring strain within the previous 12 months. Ten postural components were assessed: head erectness; shoulder symmetry; spinal curvature; hip symmetry...

AIM Our goal was to investigate the long-term results of anterior lumbar interbody fusion combined with percutaneous pedicle screw fixation for degenerative lumbar instability. MATERIAL AND METHODS Forty-seven patients that had undergone anterior lumbar interbody fusion combined with percutaneous pedicle screw fixation for degenerative lumbar instability at Tianjin Hospital between May 2003 a...

STUDY DESIGN A retrospective case-control studyOBJECTIVE.: The aim of the study was to investigate the effectiveness of selective thoracic fusion in the surgical treatment of patients with syringomyelia-associated scoliosis. SUMMARY OF BACKGROUND DATA Selective thoracic fusion technique was introduced to treat idiopathic scoliosis patients with major thoracic curve. Theoretically, such therap...

The degree of vertebral wedging, a key structural characteristic of spinal curvatures, has recently been found to be negatively related to vertebral cross-sectional area (CSA). The purpose of this longitudinal study was to examine the relation between vertebral cross-sectional growth and vertebral wedging progression within the immature lumbar spine. Using magnetic resonance imaging (MRI), we a...

Results Comparing the two populations, we found no difference in the shape parameter (pelvic incidence) for against a significant difference was demonstrated on the positional parameters (pelvic tilt and sacral slope) of the pelvis. Regarding the spine, we found a difference in the angulation of lumbar lordosis, and the orientation of the latter, as well as the number of vertebrae included in t...

Study Design Retrospective case series. Purpose To correlate functional outcomes with spinopelvic parameters in patients with high-grade spondylolisthesis (HGS) treated with instrumented in-situ surgery or reduction and fusion. Overview of Literature Satisfactory functional outcomes are reported with reduction and in-situ fusion strategies in HGS. However, reasons for this are unclear. We h...

Twenty subjects performed typing tasks on a desktop computer and touch-screen tablet in two chairs for an hour each, and the effects of chair, device, and their interactions on each dependent measure were recorded. Biomechanical measures of muscle force, spinal load, and posture were examined, while discomfort was measured via heart rate variability (HRV) and subjective reports. HRV was sensiti...

PURPOSE Patients diagnosed as thoracolumbar junction syndrome were divided into 3 treatment groups and the results of each modality were compared. MATERIALS AND METHOD 30 Patients were included in the study with the definitive diagnosis of Maigne's Syndrome. The first group received exercise therapy, the second group was treated with local steroid injections and the third group was the combin...

STUDY DESIGN A prospective imaging study. PURPOSE To characterize the distribution of the global sagittal postural patterns in asymptomatic Chinese adults using Roussouly classification. OVERVIEW OF LITERATURE The norms of sagittal parameters in asymptomatic Chinese population have been previously described, but no report described their global sagittal postural patterns as characterized by...
