OBJECTIVE To compare outcomes in the setting of spontaneous intracerebral hemorrhage (ICH) in patients taking aspirin (acetylsalicylic acid [ASA]) versus patients taking clopidogrel before hospitalization. METHODS Patients admitted to the neurosurgical service with a spontaneous ICH while taking an antiplatelet agent were prospectively identified and(More)
Patients suffering from disorders of consciousness constitute a population that exists largely outside of the daily practice patterns of neurosurgeons. Historically, treatment has focused on nursing and custodial issues with limited neurosurgical intervention. Recently, however, deep brain stimulation has been explored to restore cognitive and physical(More)
OBJECTIVE Prehospital use of antiplatelet agents has been associated with an increased risk for intracranial hemorrhage (ICH) as well as a secondary increase in ICH volume after the initial hemorrhage. Strategies to reestablish platelet aggregation are used in clinical practice, but without any established guidelines or recommendations. This article serves(More)
UNLABELLED OBJECT.: There are rare indications for upper cervical spine fusion in young children. Compared with nonrigid constructs, rigid instrumentation with screw fixation increases the fusion rate and reduces the need for halo fixation. Instrumentation may be technically challenging in younger children. A number of screw placement techniques have been(More)
OBJECT Upper cervical spine injuries in the pediatric age group have been recognized as extremely unstable from ligamentous disruption and as potentially lethal. Few measurement norms have been published for the pediatric upper cervical spine to help diagnose this pathological state. Instead, adult measurement techniques and results are usually applied(More)
BACKGROUND Primary intraosseous calvarial hemangiomas (PICHs) are generally rare and predominate (3:1) in women. Occurrence in the frontal and parietal bones is most common, but involvement of the occipital bone is exceedingly rare, representing 3 of 125 cases in a series of PICHs studied by Heckl et al. in 2000. Histopathology establishes the diagnosis of(More)
OBJECT The purpose of this study focusing on fusion rate was to determine the efficacy of recombinant human bone morphogenetic protein-2 (rhBMP-2) use in posterior instrumented fusions of the craniocervical junction in the pediatric population. The authors previously reported the short-term (mean follow-up 11 months) safety and efficacy of rhBMP-2 use in(More)
We aimed to determine the normal ranges of radial and ulnar deviation of the wrist in relation to the ulnar variance. A total of 102 healthy subjects (204 wrists) were included in the study. The ranges of radial and ulnar deviation of the wrists were measured using a universal goniometer. Ulnar variance was assessed manually or radiographically, and(More)
PURPOSE Cerebellar glioblastomas in children are rare. As a result, an optimal treatment strategy has not yet been identified. A review of the characteristics of the disease as well as the effectiveness of various therapeutic modalities would help in optimizing the treatment paradigm. METHODS We performed a detailed clinical, radiographic, and pathologic(More)
