curve flexibility in adolescent idiopathic scoliosis (ais) was one of the major concerns of spinal surgeons since the evolution of surgical correction techniques. in this respect, many tried to identify which criteria denote more rigid curve. in the present study, we aimed toward determining important factors influencing ais curve flexibility on supine bending films. we assessed radiographs of ...

BACKGROUND Spinal flexibility is determined preoperatively by manipulating the spine and assessing, radiographically, to what extent the amount of deformity reduces. Quantifying spinal flexibility is important when determining the approach to the planned operation in order to achieve the most optimal spinal correction and balance. Currently, supine traction radiography is a popular method used ...

BACKGROUND Spinal flexibility is an essential parameter for clinical decision making on the patients with adolescent idiopathic scoliosis (AIS). Various methods are proposed to assess spinal flexibility, but which assessment method is more effective to predict the effect of orthotic treatment is unclear. OBJECTIVE To investigate an effective assessment method of spinal flexibility to predict ...

BACKGROUND Thoracoscopic anterior release has been shown that it can effectively improve spinal flexibility in animal and human cadaveric studies, and has been advocated for use in patients with scoliosis. This prospective case series aims to investigate the improvement of the spinal flexibility and the effectiveness in deformity correction by anterior thoracoscopic release and posterior spinal...

Methods Height, body mass, spacing between hands, and length of the upper limbs were measured in all of the examinees. Lateral spinal curvature was identified using a bob (plummet) and clinical examination. Examinees performed five spinal flexibility tests: right and left lateral mobility test, forward bending test, shoulder static flexibility test, and neck and trunk static flexibility test. R...

Introduction Severe osteoarthritis of the hip may cause abnormal spinopelvic alignment. Therefore, spinal alignment may change after total hip arthroplasty (THA); however, there have been no prospective clinical reports on the influence of preoperative lumbar lateral flexibility on the improvement of spinal alignment. The purpose of this study was to examine the effect of preoperative lumbar la...

INTRODUCTION An unstable spine is clinically defined as the state of excessive spinal motion beyond the normal physiological limits. Muscles play an important role to provide the spinal movement and to maintain the spinal stability by increasing the bending stiffness at the same time. The issues of spinal stability controlled by the active muscular system are complicated since the numbers of mu...

The new training literature suggests that in a monopsonistic market employers will not only pay for fi rm-specifi c training but also for general training if the risk of poaching is limited. This implies that training participation should decrease when competition for employees is higher among fi rms. Using worker level data for Germany we fi nd that the hypothesis is supported empirically. Spe...
