BACKGROUND: Spinal cord injury may cause cortical reconstruction. We, therefore, explored thechanges in cortical activation before and after anterior cervical decompression and fusion surgery in patients with Hirayama disease (HD). METHODS: 17 HD cases were performed anterior cervical decompression and fusion surgery. BOLD-fMRI scan was performed preoperatively, 3 months, 6 months and 1 year after surgery. Activated voxels were compared between both hands after adjusting for head motion, slice timing, spatial normalization and image smoothing...

In patients with tumors and spinal cord lesions, inflammation and tissue infection can result in mass effect detection on imaging. As a result, surgical biopsy procedures are often performed on the lesions. We report a rare case in which the thickening ligamentum flavum (LF) appeared to be a tumor in the epidural space of the cervical spine based on imaging findings. A 52-year-old man visited our outpatient clinic with severe shoulder pain and radicular pain in his right arm that had developed gradually after a traffic accident two months earlier...

Spinal extradural arachnoid cyst (SEAC) is a rare cause of spinal cord compression. Bifocal location of thoracic and sacral SEACs is rarely reported in the literature. We report a case of thoracic spinal cord compression by SEAC associated with asymptomatic multiple sacral Tarlov cysts (TC). The surgical management and postoperative outcome of the patient are discussed. A 34-year-old woman was referred to the hospital for acute thoracic pain with a history of chronic long-standing back pain. She complained of walking difficulties...

Nicholas Fawley, Chiedozie Udeh
Sinking skin flap syndrome is a rare complication of decompressive craniectomy characterized by a sunken skin flap, neurological deterioration, and paradoxical herniation of the brain. An absent cranium allows for external compression via atmospheric pressure, causing alterations in cerebral blood flow, cerebral spinal fluid flow, and glucose metabolism, which ultimately leads to cortical dysfunction. This case report describes a patient with relatively early onset of variable neurological symptoms and imaging correlation, leading to a diagnosis and definitive therapeutic intervention with cranioplasty...

Background: Spinal cord involvement by schistosomiasis is considered to be rare. Clinical presentation of spinal schistosomiasis ranges from radicular pain to myelopathy causing flaccid paraplegia, bladder incontinence, and dysesthesia. We reported six cases with spinal schistosomiasis. Methodology: We did a retrospective analysis of the records in our department from March 1995 to March 2015, and we found that six cases of proved spinal schistosomiasis were documented, with follow-up period more than a year, aiming to find an assumption for a guideline for this ambiguous issue...

BACKGROUND: Spinal cord injuries (SCIs) are sustained by an increasing number of patients each year worldwide. The treatment of SCIs has long been a hard nut to crack for doctors around the world. Mesenchymal stem cells (MSCs) have shown benefits for the repair of SCI and recovery of function. Our present study aims to investigate the effects of intravenously infused human umbilical cord blood-derived MSCs (hUCB-MSCs) on functional recovery after subacute spinal cord compression injury of two noncontinuous segments...

Lumbar spinal stenosis causes cauda equina and nerve root compression, resulting in neurological symptoms. Although trunk flexion during level walking may alleviate these symptoms by enabling spinal canal decompression, some patients do not use this strategy. We aimed to identify the kinetic and kinematic variables that affect trunk flexion in patients during level walking. Gait was recorded in 111 patients using a three-dimensional motion capture system and six force plates. From the data recorded, walking velocity, bilateral step length, cycle time, maximum trunk flexion angle, forward pelvic tilt angle, pelvic rotation angle, maximum and minimum joint angles, and moment and power of the lower limb were calculated...

RATIONALE: CRPS after a lumbar surgery has symptoms that are similar to PSSS. However, standard criteria for distinguishing CRPS from PSSS do not exist. We present a case report of a 31-year-old female with CRPS symptoms after lumbar spinal surgery treated by performing SELD. PATIENT CONCERNS: This patient was referred to our pain clinic for left ankle pain. She received a lumbar discectomy for a herniated lumbar disc (L5/S1) but the pain was aggravated after surgery...

Acute idiopathic sudden sensorineural hearing loss (ISSNHL) following lumbar spinal surgery is an exceedingly rare phenomenon. This paper presents a case of ISSNHL presenting acutely after lumbar spine decompression and fusion treated with transtympanic steroids and hyperbaric oxygen (HBO₂) therapy. It also presents the ironic case of SSNHL secondary to presumed viral pathology sustained by the patient's operative surgeon who was treated with transtympanic steroids and HBO₂ as well. Proposed etiologies of the patient's ISSNHL include: hypotension, prone operative position, malfitted/malpositioned headrest, microemboli from a cell-saver, and nitrous oxide anesthesia...

OBJECTIVE: Type 1 Chiari malformation (CM-I) is a craniospinal disorder historically defined by cerebellar tonsillar position (TP) greater than 3-5mm below the foramen magnum (FM). This definition has come under question since quantitative measurements of cerebellar herniation do not always correspond with symptom severity. Researchers have proposed several additional radiographic diagnostic criteria based on dynamic motion of fluids and/or tissues. The present study objective was to determine if cardiac-related craniocaudal spinal cord tissue displacement is an accurate indicator of the presence of CM-I and if tissue displacement is altered with decompression...

Background: The Dynesys system remains the most widely implanted posterior non-fusion pedicle screw system. Various study designs used in investigations with good to excellent short- and mid-term results have been reported in the current literature. However, there is a lack of information concerning long-term outcomes following treatment for spinal stenosis with degenerative spondylolisthesis. Methods: The aim of our study was twofold. Firstly, to assess whether the dynamic stabilization in situ with the Dynesys System without bone grafting provides enough stability to prevent progression of spondylolisthesis and secondarily to maintain significant clinical improvement in a long-term follow-up (FU)...

OBJECTIVES: Cerebrospinal fluid leaks are a frequent complication of spinal surgery, with reported rates between 2 and 20%. Management is highly variable and dependent on comorbidities, complexity of the index procedure, and surgeons' experience. Treatment options include primary or delayed repair, with or without spinal drainage. Using a retrospective cohort, the authors aim to identify the appropriate management of iatrogenic spinal cerebrospinal fluid (CSF) leaks. PATIENTS AND METHODS: We queried our institutional database for postoperative spinal CSF leaks between 1/1/2007 and 3/14/2017 using Current Procedural Terminology (CPT) and International Classification of Disease (ICD) codes...
