Vertebral level of Tuffier's line measured by ultrasonography in parturients in the lateral decubitus position [PDF]
Korean Journal of Anesthesiology, 2014 BackgroundIt is known that Tuffier's line intersects the spine at the L4 spinous process or at the L4-L5 intervertebral space. Full term parturient women undergo various physical changes.

Creation of Three-Dimensional Solid-State Models of a Spine with Transpedicular Fixation Using a Specialized Software [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2019 Biomechanical experiments are widely used to study the mechanical characteristics of spinal elements under various types of loading. The correct construction of three-dimensional models is especially important for studying the behavior of the spine after

Upper Lumbar Pedicle Screw Insertion Using Three-Dimensional Fluoroscopy Navigation:Assessment of Clinical Accuracy [PDF]
, 2010 We used a navigation system to insert 128 pedicle screws into 69 vertebrae (L1 to L3) of 49 consecutive patients. We assessed the pedicle isthmic width and the permission angle for pedicle screw insertion. The permission angle is the angle defined by the

Measurement of scoliosis Cobb angle by end vertebra tilt angle method
Journal of Orthopaedic Surgery and Research, 2018 BackgroundScoliosis is a common deformity, and its severity is usually assessed by measuring the Cobb angle on the spinal X-ray film. The measurement of the Cobb angle is an important basis for selecting therapeutic methods and evaluating therapeutic ...

Photoacoustic imaging of a human vertebra: implications for guiding spinal fusion surgeries
Physics in Medicine and Biology, 2018 It is well known that there are structural differences between cortical and cancellous bone. However, spinal surgeons currently have no reliable method to non-invasively determine these differences in real-time when choosing the optimal starting point ...
