The speed of sound (SOS) and the broadband ultrasound attenuation (BUA), as determined by quantitative ultrasound at the calcaneum, were correlated with the bone mineral density (BMD) measurements using dual-energy X-ray absorptiometry at the femoral neck and the lumbar spine in 110 females. There were moderate correlations of 0.629, 0.623 and 0.594 between the BMD at the anterior-posterior lum...

Swinging a golf club includes the rotation and extension of the lumbar spine. Golf-related low back pain has been associated with degeneration of the lumbar facet and intervertebral discs, and with spondylolysis. Reflective markers were placed directly onto the skin of 11young male amateur golfers without a previous history of back pain. Using a VICON system (Oxford Metrics, U.K.), full golf sw...

Lumbar pain is one of the most common problems of population. Far too often it is caused by ageing and degeneration of intervertebral discs (IVD). Fusion techniques, as arthrodesis, were the first surgeries used to avoid lumbar pathologies. However, arthrodesis reduced dramatically the spine movement. So the aim of this work was to study numerically how different pathologies affect lumbar spine...

Introduction: Currently, excellent three-dimensional correction can be achieved with use of segmental pedicle screw fixation in adolescent idiopathic scoliosis (AIS). In the majority of patients with major thoracic curves, selective thoracic fusion (STF) may be considered to maximize motion segment of the unfused lumbar spine. This study aimed to investigate the extent of spontaneous derotation...

BACKGROUND Minimally invasive surgery (MIS) spine procedures were developed to limit operative time, the extent of dissection, and reduce perioperative morbidity. Here, we asked what are the "learning curves" for these MIS spine procedures? METHODS We reviewed studies in the literature that discussed the "learning curves" attributed to performing different MIS spine surgical procedures. Of in...
