STUDY DESIGN Using fresh cadavers, the biomechanical testing were used to examine the pullout strength of each pedicle screw. OBJECTIVE The aim of this study was to evaluate pullout strength of (1) a redirected pedicle screw following lateral wall breach; (2) a redirected pedicle screw following end-plate breach; and (3) a pedicle without redirection after end-plate breach without redirection...

The use of 3D ultrasound imaging to follow the progression of scoliosis, i.e., a 3D deformation of the spine, is described. Unlike other current examination modalities, in particular based on X-ray, its non-detrimental effect enables it to be used frequently to follow the progression of scoliosis which sometimes may develop rapidly. Furthermore, 3D ultrasound imaging provides information in 3D ...

STUDY DESIGN Retrospective analysis. OBJECTIVE To evaluate the correlation and reliability of cervical sagittal alignment parameters obtained from lateral cervical radiographs (XRs) compared with lateral whole-body stereoradiographs (SRs). METHODS We evaluated adults with cervical deformity using both lateral XRs and lateral SRs obtained within 1 week of each other between 2010 and 2014. XR...

Background The treatment of adults with pain from scoliosis is a complex and difficult task. The variety of structural pathologies with an adult de-novo degenerative conditions, include stenosis, joint subluxation,and disc degeneration. Mechanical pain is often associated with mal-alignment and deviations from the physiological neutral spine posture/ structure. The Side Shift approach has been ...

In many fields of spinal health care, efforts have been made to offer individualized products and therapy tailored the patient. Therefore, prevailing alignment spine must be considered, which varies from person depends on movement loading situation. With help patient-specific simulation models spine, geometrical parameters in a specific body position can analyzed, load situation structures duri...

OBJECTIVE Degenerative changes in the cervical spine are commonly accompanied by cervical kyphosis which can cause neck pain. This study examined the relationship between neck pain and cervical alignment. METHODS A total of 323 female nursing staff from our hospital were enrolled. Sagittal radiographs of the cervical spine, Body Mass Index (BMI), Visual Analogue Scale (VAS) measures of neck a...

Harrington rods are a valuable adjunct for fusion of the lumbosacral spine. Major limits of distractions are achieved with these rods. Greater amounts of decompression are possible. Decompression, alignment, and stability are maintained. Intersegmental wiring increases security and eliminates the problem of hook and rod displacement and loss of lumbar lordosis. A variety of methods are availabl...

Structurally, the sacrum-coccyx provides the dual roles of serving as the base of the spinal column while also forming part of the pelvic ring. Physiological movement control of the pelvis and the spine are functionally interdependent. In particular, intra-pelvic control, (that between the ilia and sacrum/coccyx in support and control of the forces and small movements within the pelvic ring) is...
