Dr Frank Turnbull was a pioneer neurosurgeon - the first neurosurgeon in Vancouver, Canada. He started his practice in 1933 after spending time during a neurosurgical 'residency' with Dr Kenneth Mackenzie, Canada's first neurosurgeon. Dr Turnbull practiced at a time when the perception of his speciality was dim, and the resources available to him were limited. However, Dr Turnbull overcame these obstacles, and two World Wars to help change the landscape of neurosurgery in the northwest Canada, and his career achievements also extend into medical politics and medical education...

OBJECTIVE: In defensive medicine, practice is motivated by legal rather than medical reasons. Previous studies have analyzed the correlation between perceived medico-legal risk and defensive behavior among neurosurgeons in the United States, Canada, and South Africa, but not yet in Europe. The aim of this study is to explore perceived liability burdens and self-reported defensive behaviors among neurosurgeons in the Netherlands and compare their practices with their non-European counterparts...

STUDY DESIGN: Survey. OBJECTIVE: To define the critical elements of common spine surgeries. SUMMARY OF BACKGROUND DATA: Despite significant relevance to the field of spine surgery, the term "critical element" of surgery has not been clearly defined. Every surgical procedure involves numerous steps, each with its own potential for complications and harm to the patient. Despite its crucial role in surgical training, billing, and the ethicality of concurrent surgery, the term "critical element" of surgery has not been defined...

Malignant glioma surgery involves the challenge of preserving the neurological status of patients harboring these lesions while pursuing a maximal tumor resection, which is correlated with overall and progression-free survival. Presently, several tools exist for assisting neurosurgeons in visualizing malignant tissue. Fluorescence-guided surgery (FGS) with 5-aminolevulinic acid (5-ALA) has increasingly been used during the last decade for identifying malignant glioma. Intraoperative magnetic resonance imaging (iMRI), first introduced in the mid-1990s, is being evaluated as a further tool to maximize the extent of resection...

OBJECTIVE: Stereoscopic three-dimensional (3D) imaging is increasingly used in the teaching of neuroanatomy and although this is mainly aimed at undergraduate medical students, it has enormous potential for enhancing the training of neurosurgeons. This study aims to assess whether 3D lecturing is an effective method of enhancing the knowledge and confidence of neurosurgeons, and how it compares to traditional two-dimensional (2D) lecturing and cadaveric training. METHODS: Three separate teaching sessions for neurosurgical trainees were organised: i) 2D course (2D lecture + cadaveric session), ii) 3D lecture alone, iii) 3D course (3D lecture + cadaveric session)...

Over the past half-century since Lars Leksell first utilized radiation to address deep and difficult to treat lesions of the central nervous system (CNS), intracranial stereotactic radiosurgery (SRS) has become an increasingly valued tool in the hands of neurosurgeons and radiation oncologists. Following developments in medical imaging and radiation technology, radiosurgery has evolved from its first application in movement disorders to widespread use for a varied range of malignant and benign conditions. SRS remains a powerful, minimally invasive instrument that offers additional options for intervention to a diverse patient population...

Large and giant intradural ICA aneurysms or the so-called paraclinoid aneurysms are a surgical challenge requiring high qualification of the neurosurgeon. Despite numerous publications on this topic, there is still no generally accepted classification of paraclinoid aneurysms. In this paper, we analyzed the definitions and classifications of paraclinoid aneurysms, which were available in the medical literature. The paper presents our own surgical classification of paraclinoid ICA aneurysms, which has been developed by Prof...

The ideal scalp reconstruction involves closure of the defect with similar hair-bearing local tissue in a single step. Various reconstructions can be used including primary closure, secondary healing, skin grafts, local flaps, and microvascular tissue transfer. A 53-year-old female patient suffered glioblastoma, which had recurred for the second time. The neurosurgeons performed radial debridement and an additional resection of the tumor, followed by reconstruction using a serratus anterior muscle flap with a split-thickness skin graft...

BACKGROUND: A large cranial defect combined with hydrocephalus is a frequent sequela of decompressive craniectomy (DC) performed to treat malignant intracranial hypertension. Currently, many neurosurgeons perform simultaneous cranioplasty and shunt implantation on such patients, but the safety of this combined procedure remains controversial. METHODS: We retrospectively evaluated 58 patients treated via cranioplasty and shunt implantation after DC. Twenty patients underwent simultaneous procedures (simultaneous operation group) and 38 underwent staged procedures (staged operation group)...

Ependymoma can arise throughout all compartments of the central nervous system with prevalence for intracranial and spinal location in children and adults, respectively. The current histopathology based WHO grading system distinguishes grade I, II 'classic', and III 'anaplastic' ependymoma. However, analysis of multiple cohorts of intracranial ependymoma demonstrate a wide variance in the utility of the grade II versus grade III distinction as a prognostic marker that may additionally be confounded by the anatomic compartment...

Posterior fossa houses very vital and sensitive structures namely midbrain, pons, medulla, and cerebellum. These structures are irrigated by vertebral, posterior inferior cerebellar, anterior inferior cerebellar, and superior cerebellar arteries. Parts of brain located in posterior fossa control important parts of body so any variation pertaining to stenosis, atresia, hypoplasia, fenestration, agenesis, and duplication in the arteries supplying these parts alter the irrigation pattern culminating into various morbid and mortal neurologic disorders...

Spinal subdural hematomas (SSDHs) are rare and usually associated with bleeding diatheses, trauma, iatrogenic injury, spinal vascular malformations, or intraspinal tumors. We report a case of a 75-year-old male who developed a symptomatic lumbosacral SSDH after undergoing resection of a right temporal glioblastoma multiforme. The patient subsequently recovered and was discharged home. Over the next two weeks he developed progressively worsening symptoms of lower back pain, lower extremity weakness, and urinary retention...

INTRODUCTION: Spinal disorders, particularly low back pain, are among the most common reasons for general practitioner (GP) consultation and can sometimes be a source of professional friction. Despite their frequency and published guidelines, many patients are still mistakenly referred by their GP to specialists for spinal surgery consultation which can create colleague relationship problems, suboptimal or unnessary delayed care, as well as the financial implications for patients. PURPOSE: To assess the management of GP lumbar spine referrals made to 4 neurosurgeons from 3 neurosurgical teams specialized in spinal surgery...

Neurosurgeons are getting increasingly involved in surgery for orbital tumours. The various approaches to the orbit can be challenging. The authors have demonstrated on cadavers the various approaches to the orbit which are required to be mastered by the neurosurgeon. The superior approaches which include the transcranial, supraorbital and the hybrid approaches are the most commonly utilized surgical approaches by the neurosurgeon for excision of orbital pathologies. The lateral orbitotomy is an elegant approach for excision of the tumours lateral to the optic Nerve and lacrimal gland tumours...
