BACKGROUND: Correlation between malocclusions and body posture has been discussed in the last decades, but there is still a lack of consensus in existing literature. Rasterstereography allows tridimensional reconstruction of the spine, starting from the back surface analysis. So far studies which tested modifications of rasterstereographic parameters during orthodontic treatment, comparing with those obtained from untreated control group, are not available. Clear aligner treatment produces alteration of vertical height due to the occlusal coverage and, subsequently, a stimulation of periodontal receptors which causes an inhibition of the jaw closing muscles and, hypothetically, changes in mandibular posture...

OBJECTIVES: Diffuse idiopathic skeletal hyperostosis (DISH) is characterized by anterior ossification of the spine and can lead to dysphagia and airway obstruction. The morphology of the newly formed bone in the cervical spine is different compared to the thoracic spine, possibly due to dissimilarities in local vascular anatomy. In this study the spatial relationship of the new bone with the arterial system, trachea and esophagus was analyzed and compared between subjects with and without DISH...

BACKGROUND CONTEXT: The thoracic spine was previously known as a relatively stable region in human spine. Several studies reported motion of the thoracic spine and changes in the cross-sectional area of the spinal cord changed with positions in sagittal plane. The kinematic relationship between the thoracic disc and space available for cord with the positional change is still not well investigated. PURPOSE: To evaluate the kinematic change of the intervertebral disc and space available for the spinal cord of the thoracic spine using kMRI...

BACKGROUND CONTEXT: Aggressive (Enneking Stage 3, S3) vertebral hemangiomas (VHs) are rare, which might require surgery. However, the choice of surgery for S3 VHs remains controversial because of the rarity of these lesions. PURPOSE: We reported our experience of treating S3 VHs, and evaluated the effectiveness and safety of intraoperative vertebroplasty during decompression surgery for S3 VHs. STUDY DESIGN: This is a retrospective study. PATIENT SAMPLE: Thirty-nine patients with a definitive pathological diagnosis of aggressive VHs who underwent primary decompression surgery in our department were included in this study...

Thoracic and lumbar cortical bone trajectory pedicle screws have been described in adult spine surgery. They have likewise been described in pediatric CT-based morphometric studies; however, clinical experience in the pediatric age group is limited. The authors here describe the use of cortical bone trajectory pedicle screws in posterior instrumented spinal fusions from the upper thoracic to the lumbar spine in 12 children. This dedicated study represents the initial use of cortical screws in pediatric spine surgery...

We report the first case of a young patient who presented with the features of Horner's syndrome following a spinal extradural hematoma resulting from a ruptured arterio-venous malformation (AVM). Since there were features of early compressive myelopathy as well, urgent magnetic resonance imaging (MRI) scan of the spine revealed features suggestive of an extradural hematoma in the cervico-thoracic junction. The patient underwent an emergent laminectomy with an evacuation of the hematoma. The histological features were consistent with that of an AVM...

Epidural blood patches (EBPs) are routinely used to treat symptoms (eg, headaches) associated with spontaneous intracranial hypotension. Although cerebrospinal fluid leakage commonly involves the periforaminal areas of the cervical or thoracic spine, EBPs have been historically performed at the lumbar level. Recent evidence suggests that targeting the causative spinal segment may provide greater clinical benefits. While previous reports have targeted foraminal leaks with segmental thoracic or cervical injections, we present a case report detailing the novel use of a navigable epidural catheter to perform a selective EBP at the C7/T1 foramen...

Chordoma arising from the cervical spine is rare and the traditional long-term prognosis is typically poor. Total en bloc spondylectomy with a wide margin is generally accepted to be the most appropriate management for thoracic and lumbar malignant tumors. However, this method is still challenging for the cervical spine because of the proximity of the tumor to the vertebral arteries and neural elements. Here, we report a 73-year-old man with a C5 vertebral chordoma treated with total piecemeal spondylectomy...

PURPOSE: The erector spinae plane (ESP) block has been described in the successful management of both thoracic and abdominal pain. Since the erector spinae muscle extends to the cervical spine, the ESP block may be potentially useful in painful conditions of the shoulder girdle. CLINICAL FEATURES: We performed a series of ESP blocks at the T2/T3 level in an elderly male patient with chronic shoulder pain. Immediate and profound analgesia with improved range of motion was consistently observed following the block...

BACKGROUND: Low bone mass in adolescent idiopathic scoliosis patients has been well reported. Poor bone quality was regarded as a new and unique prognostic factor in aggravating the curve progression. However, the potential biomechanical correlation between them remains unclear. METHODS: Three-dimensional finite element models of idiopathic scoliotic spine with different bone mineral status were created for axial loading simulation. Axial load of three different body weights were applied on different bone mineral mass models...

A 2 mo old golden retriever presented with malformation of the left thoracic limb and a small circular indentation of the skin in the cranial thoracic spine. Radiographs showed a cleft between the second and fifth metacarpal bones of the left thoracic limb compatible with ectrodactyly and spina bifida affecting T4 and T5 vertebrae. Magnetic resonance imaging of the thoracic spine showed dorsal reposition of the spinal cord and a tract connecting from the dura mater to the skin. No other malformations were detected...

OBJECT: Serious postoperative wound problems can frequently develop after surgery with perioperative RT for upper thoracic metastatic lesions. The figure-of-eight bandage can restrict excessive shoulder motion, which could prevent wound dehiscence. The purpose of this study was to describe the efficacy of using the figure-of-eight bandage to prevent postoperative wound dehiscence. METHODS: Between February 2005 and July 2015, we retrospectively evaluated the medical records of cancer patients who underwent surgery with or without RT for spinal metastasis involving the upper thoracic spine...
