Vertebral compression fractures (VCFs) may result in a kyphotic deformity which can cause potential systemic complications secondary to respiratory and gastrointestinal dysfunction. The use of implants in the spine for VCF treatment represents a paradigm shift away from cement injection on its own, aiming to combine the analgesic and stabilizing effect of injecting cement into the vertebral body with vertebral height restoration and kyphotic angle correction. Spine implants which can be used for VCF treatment include stents, jacks, PEEK cages and fracture reduction systems...

Background No consensus exists for the management of unstable thoracolumbar (TL) burst fractures. Surgical options include anterior, lateral, or posterior stabilization (or a combination), depending on the fracture. The potential benefits of anterior reconstruction come with increased operative time and associated morbidity. A posterior-only approach can offer stable correction without increased operative risks but may result in loss of kyphotic correction over time. Purpose To determine whether posterior-only stabilization is a viable treatment option for patients with traumatic TL fractures as opposed to anterior and combined approaches...

BACKGROUND CONTEXT: One of the characteristics of reported observations in adolescent idiopathic scoliosis (AIS) is that the thoracic spine is longer anteriorly than posteriorly, more pronounced around the apex than the transitional zones. This reversal of the normal kyphotic anatomy of the thoracic spine is related to questions of etiopathogenesis of AIS. The changes in the anatomy of the anterior column have been described rather in detail, however, the role of the posterior spinal column and the laminae has so far not been elucidated...

PURPOSE: Correction surgery for cervical degenerative kyphosis (CDK) may carry a greater risk of causing neural complications such as spinal cord injury and C5 nerve palsy because spinal canal stenosis, osteoarthritis of the facet, and consequent foraminal stenosis may coexist with CDK. We have produced an algorithmic strategy of surgical intervention for CDK, and report the outcome. METHODS: Thirty-one patients who underwent correction surgery for CDK, with a kyphotic angle of 20° or more (from 20 to 74) were involved...

The behavioral modifications associated with early motherhood, including high aggression, caring for young, and low anxiety are all affected by acute pharmacological manipulation of serotonin signaling. However, the effects on these behaviors of permanently disrupting serotonin signaling at one of its primary sources, the dorsal raphe (DR), have not been examined in detail. To address this, serotonin-specific lesions centered on the dorsomedial DR (DRdm; subregion most implicated in emotional behaviors) were induced at mid-pregnancy (day 15) or early postpartum (day 2) in rats using a saporin-conjugated neurotoxin targeting the serotonin transporter (Anti-SERT-SAP)...

BACKGROUND: The presence of bridging syndesmophytes (BS) in spinal osteotomy region serves traditionally as one critical determinant for selection of osteotomy techniques. While nowadays the proportion of kyphotic ankylosing spondylitis (AS) patients receiving pedicle subtraction osteotomy (PSO) with yet mobile neighboring disc has seen a substantial increase. Literatures investigating the clinical relevance of the presence of BS on kyphosis correction and maintenance following PSO are scarce...

OBJECTIVE: The Matthiass test serves to identify postural insufficiencies by evaluating the sagittal posture but this subjective assessment may be responsible for different reports on the prevalence of postural insufficiencies in children. Previously, rasterstereography was used to objectify this clinical test. Until now, the coupling of the Matthiass test with rasterstereography has not yet been applied to children and the reliability is unknown; therefore, the objective of our study was to provide interday and interrater reliability of rasterstereographic measurements during dynamic (modified Matthiass test) and static trials (only interday) in healthy children...
