Daniel K. Fahim, M.D. 

BACKGROUND: Tailored craniotomies for awake procedures limit cortical exposure. Recently we demonstrated that the identification of eloquent areas increased the risk of postoperative deficits. However, it was not clear whether the observed neurological deficits were caused by proximity of functional cortex to the tumor [cortical injury] or subcortical injury.

OBJECTIVE: We hypothesize that subcortical injury during tumor resection is an important predictor of postoperative neurological deficits compared to cortical injury.

BACKGROUND: The promising results of the Solitaire Flow Restoration (FR) With the Intention for Thrombectomy (SWIFT) trial recently led to Food and Drug Administration (FDA) approval of theSolitaire FR stent retriever device for recanalization of cerebral vessels in patients with acute ischemic stroke. 

OBJECTIVE: To report the early postmarket experience with this device since its FDA approval in the United States, which has not been previously described.

Long-term prospective outcomes in patients undergoing minimally-invasive spinal fusion for debilitating back pain have not been well studied. 

318 patients (mean age 63 years, range 19-94) who underwent MITLIF were followed over 7 years. Patients presented with spondylolisthesis (n = 236,

74%), and degenerative disc disease (n = 82, 26%). Health care quality of life measures studied were Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and Short Form-36 (SF36) for 7 years. Other outcomes analyzed included pre- operative co-morbidities, age, bone quality, and complications.

In this study 43 patients underwent minimally invasive transforminal lumbar interbody fusion (MITLIF) using the Staxx XD expandable interbody device. Preoperative and postoperative morphometric data (intervertebral height, foraminal height, subluxation) was collected based on plain radiographs. A validated full set of Health-related Quality of Life (HRQL) Measures, including Visual Analog Scale(VAS), Oswestry Disability Index (ODI), and SF-36 were also collected preoperativelyand postoperatively.

Periosteal_chondroma_of_the_pediatric_by_DK_FahimDaniel K. Fahim, M.D.

Periosteal chondromas located in the spine are rare. The authors document an even more infrequent occurrence of a recurrent periosteal chondroma in the cervical spine of a 6-year-old boy. During the operation, a giant (> 7 cmin diameter) periosteal chondroma with involvement of the C-5 and C-6 vertebral bodies was resected. The vertebral column was reconstructed with anterior-posterior instrumentation. The pathological examination revealed that the tumor consisted of chondroid tissue with typical chondrocytes, confirming the diagnosis of periosteal chondroma.

There is currently no biologic therapy to repair or restore a degenerated intervertebral disc. A potential solution may rest with embryonic stem cells (ESCs), which have a potential to grow indefinitely and differentiate into a variety of cell types in vitro. Prior studies have shown that ESCs can be encouraged to differentiate toward specific cell lineages by culture in selective media and specific growth environment.

complication management with mi spine procedures by m perez cruetMick J. Perez-Cruet, M.D., M.S.

Spine surgery as we know it has changed dramatically over the past 2 decades. More patients are undergoing minimally invasive procedures. Surgeons are becoming more comfortable with these procedures, and changes intechnology have led to several new approaches and products to make surgery safer for patients and improve patient outcomes.

Alzheimer’s disease is the most common form of dementia in the United States and currently affects one in eight older Americans. external_beam_radiationThe most common signs and symptoms associated with Alzheimer’s disease include difficulties with cognition, memory and behavior and these deficits can progress such that patients ultimately require assistance with daily activities. As the population ages, the incidence of Alzheimer’s is projected to increase by...

avoiding abdominal flank bulge by dk fahimDaniel K. Fahim, M.D.

The thoracolumbar junction is frequently accessed through an anterolateral approach with the incisionand muscle dissection extending from the lower thoracic region to the lateral border of the rectus abdominis muscle. This approach is frequently associated with the subsequent development of an unsightly and uncomfortable relaxation of the ipsilateral abdominal wall, or flank bulge, caused by denervation injury to the intercostal nerves.However, the etiology of this complication is not widely recognized by spine surgeons. The object of this study was to better define the relevant anatomy and innervation of the anterolateral abdominal wall musculature.
