Spinal arteriovenous fistulas (AVFs) and malformations (AVMs) are rare, complex spinal vascular lesions that challenging to manage. Recently, understanding of these has increased thanks neuroimaging technology. Published reports surgical results clinical outcome limited small series. The authors present a large contemporary series patients with AVFs AVMs who were treated at Barrow Neurological Institute in Phoenix, Arizona.Retrospective detailed review prospective database was performed for...
Atlantooccipital dislocation (AOD) in adults cannot be diagnosed with adequate specificity and sensitivity using only CT or plain radiography, the spine literature offers no guidelines. In children, most sensitive specific radiographic measurement for diagnosis of AOD is CT-based occipital condyle-C1 interval (CCI). The goal current study was to identify normal CCI healthy compare it establish a highly cutoff value neuroimaging AOD.A total 81 patients, 59 without 22 AOD, were included this...
Occipitocervical junction instability can lead to serious neurological injury or death. Open surgical fixation is often necessary provide definitive stabilization. However, long-term results are limited small case series.To review the causes of occipitocervical instability, discuss indications for intervention, and evaluate outcomes after fixation.The charts all patients undergoing posterior by senior author were retrospectively reviewed. A total 120 consecutive identified analysis. Patient...
OBJECTIVE If left untreated, occipitocervical (OC) instability may lead to serious neurological injury or death. Open internal fixation is often necessary protect the neurovascular elements. This study reviews etiologies for pediatric OC instability, analyzes radiographic criteria surgical intervention, discusses techniques, and evaluates long-term postoperative outcomes based on a single surgeon's experience. METHODS The charts of all patients < 18 years old who underwent conducted by...
Thoracic spinal cord herniation (TSCH) is rare and likely underdiagnosed. It characterized by ventral of the through a dural defect, effacement anterior subarachnoid space, increased posterior space. We present here case TSCH diagnosed surgically treated at Barrow Neurological Institute, along with supplemental intraoperative video.A 61-year-old man history progressive myelopathy causing left lower-extremity weakness associated numbness, impaired gait, foot drop, incontinence, sexual...
Cervical spondylotic myelopathy (CSM) is the primary cause of adult spinal cord dysfunction. Diminished hand strength and reduced dexterity associated with CSM contribute to disability. Here, authors investigated impact severity on function using quantitative testing evaluated response surgical intervention.
OBJECTIVE The authors assessed the rate of vertebral growth, curvature, and alignment for multilevel constructs in cervical spine after occipitocervical fixation (OCF) pediatric patients compared these results with those published reports growth normal children. METHODS radiographs CT images 18 who underwent arthrodesis. Measurements were made using postoperative follow-up available 16 to determine (cervical [CSA], C1-7 sagittal vertical axis [SVA], C2-7 SVA) curvature [CSC] lordosis angle)....
Study Design. Human cadaveric biomechanical study. Objective. The aim of this study was to evaluate the biomechanics lumbar motion segments instrumented with CD HORIZON Spire Z plate system (Spire Z), a posterior supplemental fixation spinous process plate, alone and additional systems. Summary Background Data. Plates pedicle screw/rod facet screw implants are adjuncts fusion. limits motion, improving segmental stability fusion microenvironment. However, degree which contributes overall when...
Arthrodesis is optimized when the structural graft occupies most of surface area within a disc space. The transforaminal corridor inherently limits interbody size.To evaluate biomechanical implications nested spacers (ie, second curved cage placed behind first) to increase space coverage in approaches.Seven lumbar human cadaveric specimens (L3-S1) underwent nondestructive flexibility and axial compression testing intact after instrumentation at L4-L5. Specimens were tested 5 conditions: (1)...
The role of chief White House physician has traditionally been held by an individual with a background in broad medical field, such as emergency medicine, family or internal medicine. Dr. Daniel Ruge, who served the director Spinal Cord Injury Service for Veterans Administration and was appointed during President Ronald Reagan's first term, neurosurgeon to become physician. Aside from being serve this capacity, Ruge also stands apart others have esteemed position because how he handled care...
