BACKGROUND AND OBJECTIVES: The Internet has become a primary source of health information, leading patients to seek answers online before consulting care providers. This study aims evaluate the implementation Chat Generative Pre-Trained Transformer (ChatGPT) in neurosurgery by assessing accuracy and helpfulness artificial intelligence (AI)–generated responses common postsurgical questions. METHODS: A list 60 commonly asked questions regarding neurosurgical procedures was developed....
Simultaneous fractures of C1 and C2 are increasingly common, but contemporary series limited in their evaluation.
INTRODUCTION: Mixed reality (MR) is a developing field within neurosurgery. Doppler ultrasound the conventional technique for mapping superficial temporal artery (STA); however, MR provides an opportunity to optimally map STA using patient-specific anatomic overlay. METHODS: Five patients undergoing STA-MCA bypass surgery Moyamoya between January and April 2024 were enrolled. Pre-operative CT-angiograms registered superimposed onto patient SurgicalAR(Medivis,New York,NY). Six standardized...
INTRODUCTION: Interbody subsidence is a prevalent complication post-lateral lumbar interbody fusion(LLIF) among patients with low bone mineral density(BMD). While existing metrics evaluate BMD, none offer the granularity to assess individual vertebrae. Utilizing machine learning(ML)-based automated computed tomography(CT) segmentation model, we can now achieve precise volumetric assessment of paraspinal musculature as well Hounsfield(HU) distribution throughout spine and vertebrae, serving...
INTRODUCTION: Renal cell carcinoma (RCC) spinal metastases are traditionally radioresistant to conventional external beam radiotherapy (EBRT), leading progression in pain and neurological deficit patients who refractory treatment. Stereotactic radiosurgery (SRS) can deliver higher doses of radiation fewer fractions which may overcome radioresistance. METHODS: From 2003-2023, 85 (122 lesions) undergoing SRS for RCC were analyzed. Patient demographics clinical characteristics recorded,...
Study Design Reliability analysis. Objectives Vertebral pelvic angles (VPA) are gaining popularity given their ability to describe the shape of spine. Understanding reliability and minimal detectable change (MDC) is necessary determine how these measurement tools should be used in manual assessment spine radiographs. Our aim assess intra- interobserver intraclass correlation coefficients (ICC) MDC use VPA for assessing alignment adult spinal deformity (ASD). Methods Three independent...
OBJECTIVE Vertebral compression fracture (VCF) is the most prevalent fragility fracture. When conservative management fails, patients may undergo balloon-assisted kyphoplasty (BAK). In BAK, an expandable balloon preforms a cavity in fractured vertebra before injection of bone cement. The aim this study was to compare outcomes stratified by age and frailty assessed Risk Analysis Index (RAI). METHODS A retrospective analysis 334 BAK procedures (280 patients) for osteoporotic VCFs at single...
BACKGROUND: Balloon-assisted kyphoplasty (BAK) is a minimally invasive procedure to treat vertebral compression fractures (VCF). BAK not only restores height and corrects kyphotic deformity by cement augmentation, but it also may alter spinal biomechanics, leading subsequent adjacent level VCFs. OBJECTIVES: This study aims investigate the timing, location, incidence of new VCFs following identify risk factors associated with their occurrence. STUDY DESIGN: Single-institution observational...
BACKGROUND AND OBJECTIVES: In patients experiencing pain secondary to pathological compression fractures, balloon-assisted kyphoplasty and subsequent stereotactic body radiation therapy (SBRT) may allow for restoration of vertebral height irradiation the underlying malignancy control local disease progression. The aim this study was evaluate safety efficacy treatment before SBRT in with spinal metastases benign tumors. METHODS: An analysis a prospectively collected database 70 75 metastatic...
BACKGROUND AND OBJECTIVES: The role of radiosurgery in the treatment benign intracranial tumors is well established. However, there are limited long-term follow-up studies on outcomes after stereotactic (SRS) for intradural spinal tumors. In this article, we report a large single-institution experience using SRS to treat patients with spine. METHODS: Overall, 184 (55% female) and 207 were treated. median patient age was 52 years (range: 19-93). Tumor histology included schwannoma (38%),...
Sinonasal malignant tumors (SNMTs) represent a rare and heterogeneous group of tumors. SNMTs often present late which can lead to complex, patient-specific treatment decisions. Over the last two decades, endoscopic endonasal surgery (EES) has become more frequently utilized surgical approach removing these Increasingly, studies have compared outcomes this traditional open approaches for different SNMTs. Differences in histology extent invasion impact utility EES. Negative margins are...
Case: A 69-year-old man underwent a C3-4 anterior cervical discectomy and fusion developed postoperative hypoglossal glossopharyngeal palsies that resolved with symptomatic treatment. Conclusion: Cranial nerve palsy is rare possibly under-reported injury after higher-level spine surgery. Conscientious positioning awareness of these nerves during surgical exposure are crucial to minimizing cranial palsies. Proper workup identify differentiate them from other complications necessary guide proper
