During development primary afferents grow into and establish neuronal connections in the spinal cord, thereby forming the basis for how we perceive sensory information and control our movements. In the somatosensory system, myriads of primary afferents, conveying information from different body locations and sensory modalities, get organized in the dorsal horn of the spinal cord so that spinal ...
Spinal curvatures associated with myelo meningocele represent complex problems which, if no t recognized early, determine the future ambula tory status of the patient. In recognizing the importance of functional spinal alignment, it is manda tory to supervise closely a child from infancy and to institute early protective care (Bunch et al., 1972). Spinal problems are not necessarily evident a ...
Patient-Specific Spinal Alignment and Adult Deformity Surgery: Are All Patient Deformities the Same?
dult spinal deformity is a complex pathologic procA ess with many etiologies and several mechanisms of compensation. A complete understanding of patient-specific spinopelvic alignment is required to differentiate the origin of the deformity from postural compensatory mechanisms and, ultimately, to optimize surgical correction. Specific spinopelvic parameters have been shown to be invaluable in ...
During embryogenesis the spinal cord shifts position along the anterior-posterior axis relative to adjacent tissues. How motor neurons whose cell bodies are located in the spinal cord while their axons reside in adjacent tissues compensate for such tissue shift is not well understood. Using live cell imaging in zebrafish, we show that as motor axons exit from the spinal cord and extend through ...
BACKGROUND To examine the survival function and prognostic factors of the adjacent segments based on a second operation after thoracolumbar spinal fusion. METHODS This retrospective study reviewed 3,188 patients (3,193 cases) who underwent a thoracolumbar spinal fusion at the author's hospital. Survival analysis was performed on the event of a second operation due to adjacent segment degenera...
STUDY DESIGN Multicenter, prospective, consecutive, surgical case series from the International Spine Study Group. OBJECTIVES To evaluate the effectiveness of surgical treatment in restoring spinopelvic (SP) alignment. SUMMARY OF BACKGROUND DATA Pain and disability in the setting of adult spinal deformity have been correlated with global coronal alignment (GCA), sagittal vertical axis (SVA)...
Vertebral anomalies may also distort the normal regional or global spinal alignment and necessitate some therapeutic interventions. Hemiepiphysiodesis is a traditional procedure usually described for these young patients but in more severe cases some type of osteotomy seems to be necessary. In this technical note, we describe a 5-year-old boy with failed previous hemiepiphysiodesis surgery, who...
BACKGROUND Age-related sarcopenia can cause various forms of physical disabilities. We investigated how sarcopenia affects degenerative lumbar scoliosis (DLS) and lumbar spinal canal stenosis (LSCS). METHODS Subjects comprised 40 elderly women (mean age 74 years) with spinal disease whose chief complaints were low back pain and lower limb pain. They included 15 cases of DLS (mean 74.8 years) ...
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...
