BACKGROUD: Anterior cervical discectomy and fusion (ACDF) with plate-screw construct has been gradually applied for multilevel cervical spondylotic myelopathy (CSM) in recent years. However, long cervical plate was associated with complications including breakage or loosening of plate and screws, trachea-esophageal injury, neurovascular injury, and postoperative dysphagia. To reduce these complications, the zero-profile spacer has been introduced. This meta-analysis was performed to compared the clinical and radiological outcomes of zero-profile spacer versus cage-plate construct for the treatment of multilevel cervical spondylotic myelopathy...

Sandeep Gupta, Jagdeep Singh, Jagandeep Singh Virk
PURPOSE: Complete visualization of certain acetabular fractures of posterior wall or column with cranial extension involving superior dome from standard surgical exposures is a challenge. Osteotomy of the greater trochanter has been used to enhance fracture visualization, especially the dome, in posterior and lateral exposures of the acetabulum. It also decreases the need for excessive muscle retraction. The purpose of the study was to investigate the outcome associated with trochanteric flip osteotomy in the management of certain acetabulum fractures...

This report presents the first case of a knee dislocation following septic arthritis after arthroscopy. A 65-year-old woman had an arthroscopy with irrigation and debridement (I&D) of the joint and microfracture for the chondral lesions. She had complaints of postarthroscopic infection but non-steroidal anti-inflammatory medication and local ice compression was recommended. She revisited her physician twice and at the last visit she had a large purulent effusion in her knee. The gram stain of the joint fluid aspirate demonstrated gram-positive cocci and the cultures grew methicilline-sensitive Staphylococcus aureus...

BACKGROUND: Intraoperative angiography is routinely utilized for aneurysms and arteriovenous malformations (AVMs) to verify complete occlusion and resection. Surgery for spinal and posterior fossa neurovascular lesions is usually performed in prone position. Intraoperative angiography in the prone position is challenging and there is no standardized protocol for this procedure. OBJECTIVE: To describe our experience with intraoperative angiography in the prone and lateral positions, using upper extremity arterial access...

Infrainguinal arterial occlusive disease can lead to potentially disabling and limb-threatening conditions. Revascularization may be indicated for claudication, rest pain, or tissue loss. Although endovascular interventions are becoming more prevalent, open surgeries such as endarterectomy and bypass are still needed and performed regularly. Open reconstruction has been associated with postoperative morbidity, both at the local and at the systemic levels. Local complications include surgical site infections (SSIs 0-5...

OBJECTIVE Peripheral nerve biopsy is a useful tool in diagnosing peripheral neuropathies. Sural and gracilis nerves have become the most common targets for nerve biopsy. However, the yield of sural nerve biopsy is limited in patients who have motor neuropathies, and gracilis nerve biopsy presents technical challenges and increased complications. The authors propose the intercostal nerve as an alternative motor nerve target for biopsy. METHODS A total of 4 patients with suspected peripheral neuropathies underwent intercostal nerve biopsy at the authors' institution...

Functional magnetic resonance imaging (fMRI) serves as a critical tool for presurgical mapping of eloquent cortex and changes in neurological function in patients diagnosed with brain tumors. However, the blood-oxygen-level-dependent (BOLD) contrast mechanism underlying fMRI assumes that neurovascular coupling remains intact during brain tumor progression, and that measured changes in cerebral blood flow (CBF) are correlated with neuronal function. Recent preclinical and clinical studies have demonstrated that even low-grade brain tumors can exhibit neurovascular uncoupling (NVU), which can confound interpretation of fMRI data...

A variety of complications in endoscopic third ventriculostomy have been reported, including neurovascular injury, hemodynamic alterations, endocrinologic abnormalities, electrolyte imbalances, cerebrospinal fluid leakage, fever and infection. Even though most complications are transient, the overall rate of permanent morbidity is 2.38% and the overall mortality rate is 0.28%. To avoid these serious complications, we should keep in mind potential complications and how to prevent them. Proper decisions with regard to surgical indication, choice of endoscopic entry and trajectory, careful endoscopic procedures with anatomic orientation, bleeding control and tight closure are emphasized for the prevention of complications...

BACKGROUND: Thromboembolic and hemorrhagic complications are among the most feared adverse events in the endovascular treatment of aneurysms, and this is particularly the case for flow diverter devices. Dual antiplatelet therapy has become standard of care; however, the safety, efficacy, and cost profiles of newer antiplatelet agents are not well characterized in the neurovascular context. OBJECTIVE: To compare the safety, efficacy, and cost of one of these newer agents, ticagrelor, to the most frequently used agent, clopidogrel...

Thromboembolic complications remain a major risk of endovascular neurosurgery during the treatment of intracranial aneurysms, despite the use of therapeutic heparinization and oral antiplatelet therapy when indicated. Glycoprotein (GP) IIb/IIIa inhibitors target a nonredundant pathway of platelet aggregation following adhesion and activation. Initially established and implemented in the cardiovascular arena, this drug class has provided a new tool in the neurovascular armamentarium as well. Numerous case reports, case series, and retrospective reviews have evaluated the safety and efficacy of abciximab, eptifibatide, and tirofiban in the treatment of acute thromboembolic complications during the endovascular treatment of intracranial aneurysms...

Despite a century of steady and incremental progress toward understanding the underlying biochemical mechanisms, Alzheimer's disease (AD) remains a complicated and enigmatic disease, and greater insight will be necessary before substantive clinical success is realised. Over the last decade in particular, a large body of work has highlighted the cerebral microvasculature as an anatomical region with an increasingly apparent role in the pathogenesis of AD. The causative interplay and temporal cascade that manifest between the brain vasculature and the wider disease progression of AD are not yet fully understood, and further inquiry is required to properly characterise these relationships...

BACKGROUND: Frontal fullness in Asians is often considered to indicate one's public popularity and leadership skills. Numerous materials and techniques have been applied clinically to recontour or volumize the frontal area, with variable results. The micro-autologous fat transplantation (MAFT) technique proposed by Lin et al. (2nd academic congress of Taiwan Cosmetic Association Taipei, Taiwan) in 2007 has demonstrated its feasibility in facial rejuvenation. In the present study, we used an innovative instrument to apply the MAFT technique to frontal augmentation with fat grafting and reported the results...

INTRODUCTION: Endoscopic extraperitoneal radical prostatectomy (EERPE) has gained popularity for the treatment of localized prostate cancer. However, prior complex lower abdominal or pelvic surgery can complicate subsequent EERPE. To date, there have been few reports on patients who underwent EERPE after radical resection of pT1-pT2 rectal cancer. AIM: To present our experience with EERPE in patients after radical resection of pT1-pT2 rectal carcinoma and introduce a simple and effective way to create an extraperitoneal working space...

BACKGROUND: Incarcerated medial epicondyle fractures in association with elbow trauma are rare and an absolute indication for intervention. Because of the infrequent nature, outcomes following this injury are not well documented. We studied a large cohort of these injuries to determine factors associated with functional outcomes. It was hypothesized that a greater duration between initial presentation and time of surgery would lead to poorer outcomes. METHODS: A total of 32 patients aged 18 and under who underwent surgical treatment for an incarcerated medical epicondyle fracture at a level-1 pediatric trauma center from 2003 to 2015 were identified...

Introduction: Supracondylar fracture of the humerus is the most common fracture around the elbow in children. Pinning with Kirschner wires (K-wires) after open or closed reduction is generally accepted as the primary treatment modality. However, it comes with the risk of persistent instability and if the K-wire is not inserted properly, it may cause displacement and varus deformity. We present our two-year experience with a new technique of lateral external fixation and K-wiring of the humeral supracondylar fracture...

BACKGROUND: The performance of endoscopic surgery has rapidly become widespread in neurosurgery in recent years. Endoscopy can offer close and panoramic surgical views with fine illumination, even in the deep intracranial area. However, it also has the following serious drawback: an intracranial blind area between the field lens of the endoscope and the site of the dural opening. This blind area cannot be viewed on the endoscopic monitor, and several surgical complications, including accidental intracranial neurovascular structural injury, can occur in this area...
