Unlabelled: The presence of a thoracolumbar transitional vertebra (TLTV) and/or lumbosacral transitional vertebra (LSTV) may cause wrong-site surgery and problems while measuring spinopelvic parameters, including pelvic incidence and lumbar lordosis. The Castellvi classification of LSTV addresses coronal images but not sagittal or axial images. Therefore, it is unclear how LSTV differs from the normal lumbosacral anatomy.

Objectives: Accurate confirmation of the S2AI screw trajectory with free-hand techniques is not simple, although some anatomical landmarks have been reported. To overcome the drawback, we aimed to introduce our technique for S2AI screw placement assisted with a guidewire using a new anatomical landmark.
Introduction: Previous studies reported that teriparatide (recombinant human parathyroid hormone) accelerated spinal fusion following posterior lumbar inter-body fusion surgery, and combination therapy using teriparatide and denosumab increased bone marrow density more than teriparatide alone. The purpose of this study is to evaluate the influence of combination therapy with teriparaide and denosumab on spinal fusion after posterior lumbar interbody fusion.
Materials And Methods: Sixteen osteoporotic patients with lumbar canal stenosis were randomly divided into two treatment groups, a teriparatide group (n=8; 20μg of teriparatide daily alone, administered from a month before surgery to 12 months after surgery) and a combination group (n=8; 20μg of teriparatide administered daily from a month before surgery to 12 months after surgery with 60mg denosumab every 6 months, administered at 2 and 8 months following surgery).
OBJECTIVE The aim of this study was to assess the usefulness of radiological parameters for surgical decision-making in patients with degenerative lumbar scoliosis (DLS) by comparing the clinical and radiological results after decompression or decompression and fusion surgery. METHODS The authors prospectively planned surgical treatment for 298 patients with degenerative lumbar disease between September 2005 and March 2013. The surgical method used at their institution to address intervertebral instability is precisely defined based on radiological parameters.

Therefore, this study aimed to evaluate the differences between functional and structural LLDs and to examine the correlations between LLDs and spinopelvic parameters in patients with AIS using an EOS imaging system, which permits the three-dimensional reconstruction of spinal and lower-limb bony structures.
Methods: Eighty-two consecutive patients with AIS underwent whole-body EOS radiography in a standing position between August 2014 and March 2016.

Objective: The aim of this study was to analyse the optimal trajectories for sacral alar iliac screws (SAISs) in a Japanese patient population and the clinical assessment of insertion accuracies.
Methods: The ideal trajectories of SAISs, starting from 2 mm medial to the apex of the lateral sacral crest on the midline between S1 and S2 dorsal foramina, were measured in 80 consecutive spinal disease patients (40 males and 40 females; average age: 67.4 ± 8.

Background: The sagittal vertical axis (SVA) is important in the evaluation of spinal sagittal balance. Although the "fists-on-clavicles" (FOC) position has been widely used in radiographic examinations, it does not define shoulder flexion in detail. Meanwhile, in EOS imaging, the "hands-on-cheeks" (HOC) position is widely used but has not been well investigated.
