Infants with an immobile arm may be easily overlooked in primary care settings. Differential diagnoses include injuries, infections, neuropathies, ischemia and rarely, neoplasms. We report the case of a one-year-old boy with weakness in his left arm after minor trauma with a diagnosis of brachial plexus palsy initially. After rehabilitation for 2months, his weakness progressed to unsteady gait and quadriparesis. MRI revealed a huge solid tumor in the left supraclavicular fossa, which also involved the left brachial plexus, upper thoracic cavity, and left paravertebral space with invasion into the spinal canal...

PURPOSE OF REVIEW: The current review describes the current evidence on pediatric spinal cord injury without radiographic abnormality (SCIWORA) with attention to the definition, epidemiology, and clinical presentation of the condition, as well as common MRI findings, management strategies, and outcomes. RECENT FINDINGS: Recent literature demonstrates that with more widespread MRI use, our understanding of SCIWORA has improved. The new literature, although still limited, provides a more granular conceptualization of patterns of injury as well as potential prognostic stratification of patients based on MRI findings...

Atlas-based autosegmentation is an established tool for segmenting structures for CT-planned head and neck radiotherapy. MRI is being increasingly integrated into the planning process. The aim of this study is to assess the feasibility of MRI-based, atlas-based autosegmentation for organs at risk (OAR) and lymph node levels, and to compare the segmentation accuracy with CT-based autosegmentation. Fourteen patients with locally advanced head and neck cancer in a prospective imaging study underwent a T1-weighted MRI and a PET-CT (with dedicated contrast-enhanced CT) in an immobilization mask...

Dance involves exemplary sensory-motor control, which is subserved by sophisticated neural processing at the spinal cord and brain level. Such neural processing is altered in the presence of nociception and pain, and the adaptations within the central nervous system that are known to occur with persistent nociception or pain have clear implications for movement and, indeed, risk of further injury. Recent rapid advances in our understanding of the brain's representation of the body and the role of cortical representations, or "neurotags," in bodily protection and regulation have given rise to new strategies that are gaining traction in sports medicine...

The aim of this study is to determine whether stereotactic body radiotherapy for multiple vertebral metastases treated with a single isocenter results in greater intrafraction errors than stereotactic body radiotherapy for single vertebral metastases and to determine whether the currently used spinal cord planning organ at risk volume and planning target volume margins are appropriate. Intrafraction errors were assessed for 65 stereotactic body radiotherapy treatments for vertebral metastases. Cone beam computed tomography images were acquired before, during, and after treatment for each fraction...

BACKGROUND: Controversy exists regarding the management of unstable Jefferson fractures, with some surgeons performing reduction and immobilization of the patient in a halo vest and others performing open reduction and internal fixation. This study compares the clinical and radiological outcome parameters between posterior atlantoaxial fusion (AAF) and occipitocervical fusion (OCF) constructs in the treatment of the unstable atlas fracture. MATERIALS AND METHODS: 68 consecutive patients with unstable Jefferson fractures treated by AAF or OCF between October 2004 and March 2011 were included in this retrospective evaluation from institutional databases...

Acute traumatic spinal cord injury (SCI) is a devastating disease process affecting tens of thousands of people across the USA each year. Despite the increase in primary prevention measures, such as educational programs, motor vehicle speed limits, automobile running lights, and safety technology that includes automobile passive restraint systems and airbags, SCIs continue to carry substantial permanent morbidity and mortality. Medical measures implemented following the initial injury are designed to limit secondary insult to the spinal cord and to stabilize the spinal column in an attempt to decrease devastating sequelae...

INTRODUCTION: Fractures of the proximal tibial epiphysis rare. It has been estimated that fractures of the upper tibial epiphysis account for 0.5-3.1% of all epiphyseal injuries. Who had no neurovascular deficit, with fixed extension deformity at the left knee was treated early with closed reduction techniques. CASE REPORT: We present a case of a 16-year-old boy who while playing cricket on the road was hit by a car. The patient presented in emergency room with extremely swollen knee and soft tissue swelling (hemarthrosis), he was unable to lift his leg actively due to severe pain because of hamstrings spasm, and he had no wound over his left knee and had no other associated injuries...

Effective treatments promoting axonal regeneration and functional recovery for spinal cord injury (SCI) are still in the early stages of development. Most approaches have been focused on providing supportive substrates for guiding neurons and overcoming the physical and chemical barriers to healing that arise after SCI. Although collagen has become a promising natural substrate with good compatibility, its low mechanical properties restrict its potential applications. The mechanical properties mainly rely on the composition and pore structure of scaffolds...

INTRODUCTION: Cruciate Paralysis is a rare incomplete spinal cord syndrome presenting as brachial diplegia with minimal or no involvement of the lower extremities. It occurs as a result of trauma to the cervical spine and is associated with fractures of the axis and/or atlas. Diagnosis is confirmed on MRI and is managed by treatment of the underlying pathology. Prognosis depends on the extent of spinal cord injury and the exact cause. CASE PRESENTATION: A 20-year-old male presented to the casualty with a history of an injury to the back of the head as a result of a fall...

BACKGROUND CONTEXT: Although most cadaveric studies of the Recurrent Laryngeal Nerve (RLN) have focused on course variations, they have usually been done on preserved (fixed and embalmed) cadavers, which renders the RLN immobile and of less surgical landmark value. PURPOSE: Our aim was to perform a thorough exposure in fresh cadavers, with the intention of investigating the Inferior Thyroid Artery (ITA) and Berry's ligament as reliable landmarks for the identification of the RLN in anterior cervical spine surgery...

BACKGROUND: The recommended practice for over 30 years has been to routinely immobilize patients with unstable cervical spinal injuries using cervical spinal collars. It is shown that patients with Ankylosing spondylitis (AS) are four times more likely to suffer a spinal fracture compared to the general population and have an eleven-fold greater risk of spinal cord injury. Current protocols of spinal immobilization were responsible for secondary neurologic deterioration in some of these patients...

INTRODUCTION: Atlantoaxial rotational fixation (AARF) is a rare entity in adults, with only a few cases reported in the English literature and often associated with a traumatic mechanism. It is an underdiagnosed condition that must be taken into account in the initial assessment of all craniocervical trauma. Both diagnostic and therapeutic delay may be a potential cause of severe neurological damage or even death of the patient. The therapeutic management is controversial given the difficulty of achieving optimum stability and permanent reduction...

Bone fracture with subsequent immobilization of the injured limb can cause complex regional pain syndrome (CRPS) in humans. Mechanisms of CRPS are still not completely understood but bone fracture with casting in mice leads to a similar post-traumatic inflammation as seen in humans and might therefore be an analog to human CRPS. In this article we report behavioral and spinal electrophysiological changes in mice that developed swelling of the paw, warming of the skin, and pain in the injured limb after bone fracture...
