Over the past decade computer aided, navigated surgery has evolved from early laboratory experiments to an indispensable tool for many interventions in spine surgery. Accurate patient registration with the pre-operative imaging modalities or referencing of the target anatomical structure is an essential component of these procedures. Many of today’s approaches are invasive and use either mechan...

BACKGROUND Knowledge of the anatomical variation of the vertebral artery has clinical importance not only for the performance of interventional or surgical procedures itself but also to ensure their safety. We conducted a study of the anatomical variation by reviewing multi-detector computed tomography (MDCT) images of the cervical spine from 460 Korean patients. METHODS 16-row MDCT data from...

The height, width, and cross-sectional area of the vertebral canal and spinal cord along with the area ratio of spinal cord to vertebral canal in the cervical vertebra were evaluated in images obtained using computed tomography (CT). Measurements were taken at the cranial, middle, and caudal point of each cervical vertebra in eight clinically normal small breed dogs (two Shih Tzu, two Miniature...

Aim: The current study aimed to evaluate the late-term results of patients operated for lumbar spine fractures in our clinic. 
 Material and Method: 134 from January 2012 2020 were treated with “short-segment pedicle instrumentation” neurosurgery department. Patients a burst fracture single vertebra included. final sample consisted 67 who followed up over years radiographs before after sur...

The German Shepherd is among the breeds most prone to pathologies of lumbosacral spine. aim study was examine how presence spine pathology affects shape lumbar and dimensions individual vertebrae. Mathematical analysis consisted three measurements for each vertebra. Based on analysis, it concluded that there a correlation between height first five vertebrae occurrence transitional vertebra (LTV...

OBJECTIVE To establish normative data for spinal canal AP diameter from cervical vertebra to sacrum in the Korean young and to assess the exposed spinal canal after laminectomy which was related with restenosis by post-laminectomy membrane formation. METHODS From PET/CT, axial bone-window CT of 83 young adults (20-29 years) were obtained, and we measured AP diameters of C3, C5, C7, T1, T4, T8...

Context: The first cervical vertebra, Atlas has different features from other vertebra. Cervical vertebra is an important part of bony anatomy craniovertebral junction. stability atlas provided by two symmetrical lateral masses that are united anterior and posterior arches. These the most bulky solid parts atlas, supportive elements composed superior inferior articular facets. spine violated va...

The purpose of this study was to quantify the magnitude and frequency content surface-measured accelerations at each major human body segment from foot head during impact landings. Twelve males performed two single leg drop landings 0.15 m, 0.30 0.45 m. Triaxial accelerometers (2000 Hz) were positioned over the: first metatarsophalangeal joint; distal anteromedial tibia; superior medial femoral...
