Applying a three-dimensional curved lumbar spine model to simulate surgery for training residents in pedicle screw insertion.

Purpose: The challenges of spinal surgery can be overcome by deeply understanding the anatomical and surgical complexities of the region through the use of model simulators. This study investigates the impact of digitally designed simulators, specifically lumbar spinal models with abnormal curvature, on preoperative planning and their effectiveness as training tools. The study addresses challenges in spine surgery, such as unique deformities, classification issues, and associated abdominal structure abnormalities.

Assessment of failure risks during C2 vertebra pedicle screw insertion using three-dimensional computed tomography angiography analysis: the role of high-riding vertebral artery and narrow pedicles.

Background: Cervical fixation is a common treatment for conditions like vertebral fractures, osteosarcoma, osteomyelitis, arthritis, and congenital disorders. The study was designed to assess the occurrence of high-riding vertebral artery (HRVA), narrow C2 pedicles (NC2P) and ponticulus posticus (PP), which pose risks of injuring vertebral artery (VA) during screw placement in cervical fixation procedures.

Methods: The study examined the prevalence of HRVA, NC2P and PP in 382 pedicle sides of the C2 vertebra using computed tomographic angiography scans.

Using Photogrammetry to Analyze Anatomical Changes in the Nipple in Juvenile and Adolescent Scoliosis Patients.

Background: The need for an objective set of anterior trunk measurements, such as nipple and clavicular shoulder joints, is essential to quantify the anterior asymmetry present in scoliosis. This study aims to characterize breast asymmetry (BA) in young individuals with scoliosis using photogrammetry.

Methods: Digital photographs of the anterior trunk of the 51 scoliosis patients aged 4-20 years were taken from an anterior perspective.

Analysis of the Thigh Aesthetic Profiles: One of Physical Ideal Body Proportions.

Background: The contour of the thigh is increasingly being recognized as crucial component of the ideal human physique, giving rise to heightened interest in attaining the perfect thigh profile. Notwithstanding, the contemporary landscape of cosmetic surgery appears to be bereft of efficient and precise objective methodologies to evaluate the outcomes of thigh contouring treatments. The present study is aimed to investigate the aesthetic appeal of varying thigh contours, employing specialized software as an indispensable instrument for quantitative and qualitative analysis.
