BACKGROUND: Adolescent idiopathic scoliosis is a complex three-dimensional deformity of the spine characterized by deformities in the sagittal, coronal, and axial planes. Spinal fusion using pedicle screw instrumentation is a widely used method for surgical correction in severe (coronal deformity, Cobb angle > 45°) adolescent idiopathic scoliosis curves. Understanding the anatomic difference in the pedicles of patients with adolescent idiopathic scoliosis is essential to reduce the risk of neurovascular or visceral injury through pedicle screw misplacement...

BACKGROUND: The transcondylar approach (TCA) has gained importance in recent era which enables shorter and direct route to access the lesions ventral to the brainstem. The important step in this approach is resection of the occipital condyle (OC). The detailed knowledge of bony anatomy of OC and its relation to the hypoglossal canal (HC), condylar canal (CC), and jugular foramen (JF) is very important to avoid any iatrogenic injury during craniovertebral surgeries. The aim of the present study is to conduct a morphometric and morphological study and note the variations of the OC and the structures surrounding it in North Indian population...

The cranial base is a complex 3-D region that contains critical neurovascular structures. Pathologies affecting this region represent some of the most challenging lesions to manage due to difficulty with access and risk of significant postoperative morbidity. With the development of expanded endonasal endoscopic approaches, skull base surgeons use the nose and paranasal sinuses as a corridor to access selected ventral skull base lesions. This review discusses high-resolution imaging in the evaluation of patients with skull base lesions considered for endonasal endoscopic surgery, summarizes various expanded endonasal endoscopic approaches, and provides examples of commonly used expanded endonasal endoscopic procedures...

INTRODUCTION: The complications related to revision for acetabular component protrusion with material migrating into the intrapelvic region remain rare but potentially serious. Today, the literature reports no epidemiological data on the subperitoneal approach (SPA) in revision total hip arthroplasty (RTHA) for protrusion. Therefore we conducted a retrospective study on a large revision arthroplasty database to answer the following questions: 1) What is the frequency of this approach in this population? 2) What are the factors related to this procedure? 3) Is morbidity and mortality of the SPA higher than for an isolated conventional approach? HYPOTHESIS: Major protrusions with material in the superomedial quadrant (SMQ)have a higher probability of being operated using a SPA...

Chordoid glioma of the third ventricle is a rare and challenging tumor to surgery because of its unique anatomical location and its close juxtaposition to the neurovascular structures and hypothalamus. The authors report a case of chordoid glioma of the third ventricle in a 43-year-old woman, who presented with headache and somnolence. The tumor was approached by endoscopic transnasal technique with a favorable result. Histopathologic examination disclosed a neoplastic tissue composed of eosinophilic epithelioid cells, mucinous, periodic acid Schiff-diastase positive, extracellular matrix, and scattered lymphoplasmacytic infiltrates...

OBJECTIVE: The inter-rater reliability of the modified Knosp's classification was measured before the analysis. The clinical validity of the parasellar extension grading system was evaluated by investigating the extents of resection and complication rates among the grades in the endoscopic endonasal transsphenoidal surgery (EETS) for pituitary adenomas. METHODS: From November 2008 to August 2015, of the 286 patients who underwent EETS by the senior author, 208 were pituitary adenoma cases (146 non-functioning pituitary adenomas, 10 adrenocorticotropic hormone-secreting adenomas, 31 growth hormone-secreting adenomas, 17 prolactin-secreting adenomas, and 4 thyroid-stimulating hormone-secreting adenomas; 23 microadenomas, 174 macroadenomas, and 11 giant adenomas)...

Intraoperative indocyanine green(ICG)videoangiography is simple, less invasive, and enables real-time observation of hemodynamics during neurovascular surgery. In this article, we describe a case of ruptured distal middle cerebral artery aneurysm, which was unclippable and required parent artery occlusion with extracranial-intracranial bypass. Under temporary clipping of the proximal vessel, ICG videoangiography demonstrated the proper target vessel for bypass through delayed and retrograde filling of the dye...

Endoscopy in cerebellopontine angle surgery is an increasingly used technique. Despite of its advantages, the shortcomings arising from the complex anatomy of the posterior fossa are still preventing its widespread use. To overcome these drawbacks, the goal of this study was to define the anatomy of different endoscopic approaches through the retrosigmoid craniotomy and their limitations by surgical windows. Anatomical dissections were performed on 25 fresh human cadavers to describe the main approach-routes...

BACKGROUND: Implication of veins as neurovascular conflict (NVC) in the genesis of trigeminal neuralgia (TN) remains a matter of debate. Few reports dealing with venous NVC have been published. The objective of this study is to describe the outcome in a historical cohort of consecutive patients with classical TN due to venous compression. METHODS: All patients with TN treated by microvascular decompression (MVD) from 2005 to 2013 were included if a marked venous compression was found at the surgery either alone or accompanied by an artery...

Congenital brachial artery true aneurysms are exceedingly rare. Most are pseudoaneurysms secondary to trauma or infection. We report a boy aged 2 years who presented with painless, pulsatile swelling on the medial aspect of the right arm, 4 cm above the elbow joint that had been present since birth. Spiral CT angiography showed a fusiform aneurysm of the distal right brachial artery with a peripheral crescent-shaped thrombus. Distal arteries were normally opacified. There was no evidence of abnormal dilation or stenosis in any other artery...

: Reports on different types of surgical procedures show that night-time surgeries are often associated with a high number of complications than daytime surgeries. However, there are no data, and hence evidence that relate the outcome of supracondylar humeral fractures in children to the time of the day when the respective surgical procedure is implemented. In this study, we analyze the clinical and radiological outcomes of pediatric supracondylar humeral fractures surgically treated during daytime and night-time hours...

Denonvilliers fascia is a dense structure between the rectum and the genitourinary system, and plays as a barrier. In recent years, along with in-depth study of TME, scholars have taken many discussions on Denonvilliers fascia structure and the dissection plane. On the one hand, some consensus have been made on Denonvilliers fascia structure, but still needs to further clarify its microstructure. On the other hand, scholars have generally recognized the neurovascular bundles are on Denonvilliers fascia sides...

BACKGROUND CONTEXT: Pedicle screw fixation is commonly employed for the surgical correction of scoliosis but carries a risk of serious neurovascular or visceral structure events during screw insertion. To avoid these complications, we have been using a computed tomography (CT)-based navigation system during pedicle screw placement. As this could also prolong operation time, multi-level registration for pedicle screw insertion for posterior scoliosis surgery was developed to register 3 consecutive vertebrae in a single time with CT-based navigation...

BACKGROUND: The pucker sign, also called skin tenting, indicates significant displacement of the supracondylar fracture and can be a cause for alarm. The purpose of this study is to compare a cohort of patients with type III supracondylar fractures presenting with a pucker sign to a group without a pucker sign by evaluating neurovascular injury at presentation, need for open reduction, persistent neurovascular injury, range of motion, and carrying angle at final follow-up. METHODS: A retrospective review was performed for Gartland type III extension type supracondylar fractures...
