Management for chordoma of the spine and sacrum with stereotactic radiosurgery Open
OBJECTIVE Resection for spinal and sacral chordoma is associated with significant morbidity and high rates of local recurrence. Stereotactic radiosurgery (SRS) offers radiobiological benefits over conventional radiation therapy and has eme…

Surgical management of spinal intradural hematomas: illustrative cases Open
BACKGROUND Spinal intradural hematoma (SIH) is a rare condition with potential for permanent neurological deficit. SIH can be managed conservatively with serial imaging or surgically with lumbar drainage or open evacuation. We present 3 SI…

Occipitocervical surgery rescue: The “Catcher’s Mitt” technique Open
Instability of the occipitocervical junction may compress neural elements, resulting in progressive disability. After the Kickstand Rod technique was developed to correct for thoracolumbar scoliosis, the Candy Cane construct was developed …

Intradiscal Osteotomy and Bilateral Expandable Transforaminal Interbody Fusion Cages for Iatrogenic Kyphotic Deformity: A Technical Report Open
Objectives Expandable transforaminal interbody fusion (TLIF) devices have been developed to introduce more segmental lordosis through a narrow operative corridor, but there are concerns about the degree of achievable correction with a smal…

Serial Neuroendoscopic Lavage for the Treatment of Elevated Cerebrospinal Fluid Protein Levels in Infants with Gram-Negative Rod Ventriculitis Open
Introduction: Gram-negative rod (GNR) bacterial ventriculitis is a rare complication of shunt-dependent hydrocephalus, often requiring an extended and invasive treatment course. Accumulation of purulent material, as well as e…

Gonococcal Infection and Ventriculoperitoneal Shunts Open
Neisseria gonorrhoea e and Chlamydia trachomatis are pathogens commonly isolated in pelvic inflammatory disease. Neisseria gonorrhoea e may uncommonly spread outside the urogenital tract to cause complications. We present 2 cases of adoles…

Does stroke etiology influence outcome in the posterior circulation? An analysis of 107 consecutive acute basilar occlusion thrombectomies Open
OBJECTIVE Acute basilar artery occlusion (BAO) harbors a more guarded prognosis after thrombectomy compared with anterior circulation large-vessel occlusion. Whether this is a function of a greater proportion of atherosclerotic/intrinsic l…

Does the obesity paradox predict functional outcome in intracerebral hemorrhage? Open
OBJECTIVE Being overweight or mildly obese has been associated with a decreased risk of death or hospitalization in patients with cardiovascular disease. Similarly, overweight patients admitted to an intensive care unit (ICU) have improved…

Three-dimensional, computer simulated navigation in endoscopic neurosurgery Open
Three-dimensional, frameless neuronavigation systems are useful in endoscopic neurosurgery to assist in the pre-operative planning of potential trajectories and to help localize the pathology of interest. Neuronavigation appears to be a…

Liver Stiffness Decreases Rapidly in Response to Successful Hepatitis C Treatment and Then Plateaus Open
LS decreased from pre-treatment to SVR24, but did not decrease significantly during additional follow-up. Earlier treatment may be needed to reduce the burden of liver disease.
