Although porcupine quill injuries are common in dogs, the detailed appearance of the quill on diagnostic ultrasound, computed tomography, and magnetic resonance imaging has not been sufficiently described. A 4-year-old, intact, female Jack Russel terrier presented with severe neck pain and ataxia after an altercation with a porcupine 2 weeks earlier. Radiology, diagnostic ultrasound, computed tomography and magnetic resonance imaging were all utilised to identify a quill imbedded in the cervical vertebral canal and cervical musculature and were compared to each other...

With the increase of elderly population, orthopaedic surgeons need to deal with the diseases related to aging, such as joint disorders and fragility fractures. The number of total joint replacements, for example, is two times more than it was 10 years ago. With these backgrounds, the Japanese Orthopaedic Association (JOA) has proposed the concept of locomotive syndrome; conditions under which the elderly have been receiving care services due to problems of the locomotive organs. To prevent geriatric or disuse syndrome, JOA is currently providing the care‒prevention programs such as the loco-check and loco-training...

The contribution of left-right reciprocal coupling between spinal locomotor networks to the generation of locomotor activity was tested in adult lampreys. Muscle recordings were made from normal animals as well as from experimental animals with rostral midline (ML) spinal lesions (~13%→35% body length, BL), before and after spinal transections (T) at 35% BL. Importantly, in the present study actual locomotor movements and muscle burst activity, as well as other motor activity, were initiated in whole animals by descending brain-spinal pathways in response to sensory stimulation of the anterior head...

A 25-year-old male patient with severe thigh and right side pain was presented. In the lumbar magnetic resonance images, there was a contrasting spinal cord tumor image with 1 cm in diameter at the level of the L3 vertebra. The patient was operated and the tumor was totally removed. All the pain of the patient recovered. The patient's postoperative two days were very comfortable and the patient was early mobilized. On the third postoperative day, the patient complained of severe headache, nausea and vomiting...

BACKGROUND: A subdural hematoma refers to a collection of blood between the dura and the arachnoid membranes and is classified into acute, sub acute and chronic. Subdural hematoma has been referred to as the "great neurologic imitator" as it can mimic many neurological conditions. CASE PRESENTATION: Forty-three year old Sri Lankan female presented 2 weeks following traumatic head injury with bilateral flaccid complete paraplegia and urinary retention. Her non-contrast computer tomography of the brain revealed bilateral acute, chronic subdural hematomas...

Evoking motor potentials are an objective assessment method for neuromotor function, yet this was to our knowledge never done in neonatal lambs. There is neither a method for standardized quantification of motor evoked potentials (MEPs). We first aimed to evaluate the feasibility of MEP recording in neonatal lambs and test its validity. Second we aimed to develop an algorithm for its quantification and test its reliability since manual input is required. We recorded myogenic MEPs after transcranial motor cortex stimulation in 6 lambs aged 1-2 days...

This study was carried out to derive reference value of normal spine indices, and to evaluate the feasibility of the indices for computed tomography (CT). CT images and magnetic resonance imaging were acquired from clinically normal 12 beagle dogs for normal group and 50 dogs with 56 spinal disorders for patient group. Image acquisition regions were cervical spine (C2 to T1), thoracic spine (T1-T13) and lumbar spine (L1-L7). The measured indices are as follows; the ratio of width to height of spinal cord include dura matter (CR) and vertebral foramen (FR), and the ratio of cross sectional area of spinal cord to vertebral foramen (CFAR)...

Reconstruction of the visceral and intercostal arteries is the most challenging part in the open repair of thoraco-abdominal aortic aneurysm. For efficient and expeditious reconstruction of these branching vessels, a technique of using a pre-handsewn 8-branch aortic graft (octopod technique) has been adopted. The octopod graft was manually constructed using commercially available two 4-branch aortic grafts that were spatially oriented based on the preoperative computed tomographic images and connected each other prior to surgery...

Background: Complete or incomplete spinal cord injury (SCI) results in varying degree of motor, sensory and autonomic impairment. Long-lasting, often irreversible disability results from disconnection of efferent and afferent pathways. How does this disconnection affect brain function is not so clear. Changes in brain organization and structure have been associated with SCI and have been extensively studied and reviewed. Yet, our knowledge regarding brain connectivity changes following SCI is overall lacking...

Electric fields have been studied extensively in biomedical engineering (BME) for numerous regenerative therapies. Recent studies have begun to examine the biological effects of electric fields in combination with other environmental cues, such as tissue-engineered extracellular matrices (ECM), chemical gradient profiles, and time-dependent temperature gradients. In the nervous system, cell migration driven by electrical fields, or galvanotaxis, has been most recently studied in transcranial direct stimulation (TCDS), spinal cord repair and tumor treating fields (TTF)...

OBJECTIVE: Brain-computer interface (BCI) technology aims to provide individuals with paralysis a means to restore function. Electrocorticography (ECoG) uses disc electrodes placed on either the surface of the dura or the cortex to record field potential activity. ECoG has been proposed as a viable neural recording modality for BCI systems, potentially providing stable, long-term recordings of cortical activity with high spatial and temporal resolution. Previously we have demonstrated that a subject with spinal cord injury (SCI) could control an ECoG-based BCI system with up to three degrees of freedom [Wang et al...

Thoracolumbar myelopathy encompasses a number of disease processes such as intervertebral disc disease, discospondylitis, trauma, congenital malformations, neoplasia, and intramedullary spinal cord disease. Compressive disc herniations are most common in dogs and require imaging procedures such as myelography, computed tomography (CT), and/or magnetic resonance imaging (MRI) to determine the need and location for decompressive surgery. The purposes of this retrospective, cross-sectional study were to evaluate all dogs undergoing thoracolumbar CT imaging as the initial diagnostic step between 2010 and 2015 and determine whether any of the imaging characteristics could be used to predict the need for additional imaging in the form of myelography, CT myelography, and/or MRI...

Sarcoidosis is an inflammatory granulomatous disease that is systemic, but bone involvement is uncommon. A 68-year-old man was referred to our hospital complaining of right shoulder pain with numbness. Computed tomography revealed systemic lymphadenopathy and multiple bone lesions. Because malignant lymphoma with a mass lesion protruding into the vertebral canal was considered, he underwent urgent radiotherapy. Thereafter, a needle biopsy of the left parasternal node was performed and showed epithelioid granulomas, confirming a diagnosis of sarcoidosis...

Atlanto-axial (AA) instability due to ligament insufficiency is a common cause of cervical spinal cord compression in toy breeds. However, in some dogs a difference in size between the atlas and the axis leads to joint incongruence that exacerbates AA subluxation and makes surgical treatment challenging. Twelve dogs with AA instability with incongruence were enrolled in a single institution prospective observational study. Computed tomography (CT) and magnetic resonance imaging (MRI) of the AA joint were compared to a retrospectively reviewed control group...

Intrathecal delivery is a procedure involving the release of therapeutic agents into the cerebrospinal fluid (CSF) hrough a catheter. It holds promise for treating high-impact central nervous system pathologies, for which systemic administration routes are ineffective. In this study we introduce a numerical model able to simultaneously account for solute transport in the fluid and in the spinal cord. Using a Discontinuous Galerkin method and a three-dimensional patient-specific geometry, we studied the effect of catheter position and angle on local spinal cord drug concentration...

Cervical transforaminal epidural steroid injection (TFESI) under the guidance of computed tomography (CT) can offer great anatomical resolution and precise needle placement in the axial plane. However, some complications, including blood pressure surge, allergic reactions, vasovagal syncope, and cerebral infarct, have been reported after CT-guided cervical TFESI. We report the first case of iatrogenic spinal cord injury (SCI) during a CT-guided cervical TFESI. A 67-year-old woman, upon receiving TFESI on Lt...
