Chapter
The most common neoplasms in intradural extramedullary compartment of cervical spine are meningiomas and peripheral nerve sheath tumors (NST)—schwannomas and neurofibromas. Magnetic resonance imaging with contrast administration is the gold standard method that distinguishes lesions in the intradural extramedullary space from tumors in the other sp...

Background: Surgical risk in patients with unruptured aneurysms is well known. The relative impact of surgery and natural history of subarachnoid haemorrhage (SAH) on patients in good clinical condition (World Federation of Neurological Surgeons [WFNS] grades 1 and 2) is less well quantified. The aim of this study was to determine causes of poor o...

Vazospazmus je způsoben přítomností krve v subarachnoidálním prostoru. Rozpadové produkty krve, zejména oxyhemoglobin, spouští kaskádu událostí, které finálně vedou ke svalové kontrakci uvnitř stěny tepny nebo k strukturálním změnám se ztluštěním stěny artérie. Grafické vazospazmy jsou viditelná zúžení mozkových cév znázorněná na digitální subtrakč...
Article
Acute symptomatic occlusion of extracranial internal carotid artery (eICA) can lead to a critical and potentially devastating stroke associated with high morbidity and mortality. Optimal treatment remains unclear. We analyzed our institutional experience with emergent surgical recanalization of acutely occluded eICA. Retrospective analysis of hospi...
Chapter
Intramedullary astrocytoma is one of the less common tumors of the central nervous system. The impact of prognostic factors on survival can play a major role in treatment planning and help in patient counseling; however conflicting conclusions are reported in the literature. We try to assess the importance of various patient-, tumor- and treatment-...

Hydrocephalus is a relatively common complication of subarachnoid hemorrhage. Hydrocephalus is classified as acute, subacute or chronic according to the time elapsed from the onset of subarachnoid hemorrhage. Etiology involves either an obstruction of cerebrospinal fluid (CSF) flow or disturbed CSF resorption. Hydrocephalus in urgent situations is...
Article
Quadrigeminal cistern and the surrounding anatomical structures with the pineal gland at their center are usually referred to as pineal region. Due to great histological diversity of this location, the list of possible local expansions is relatively extensive, ranging from benign pineal cysts to highly malignant tumors. Neoplasms of the pineal regi...
Article
The authors describe their experience with treatment of two neurologically intact male patients, aged 70 and 74 years, presenting with combined lateral atlanto-axial dislocation and odontoid type II fracture. The mechanism of these two craniovertebral junction injuries had been lateroflexion of the neck. The initial attempt at closed reduction usin...

Spontaneous spinal epidural hematoma is a rare clinical entity. It represents less than 1 % of all lesions located in the epidural space of the spinal canal. Our case report describes 63-year-old patient admitted for a suddenly incurred intense neck pain and paresthesia in the right upper limb with progression to severe right spasic hemiparesis. Th...
Chapter
Substantial amount of patients treated because of upper cervical spine (UCS) and craniovertebral junction (CVJ) instability and/or deformity are those who suffer from rheumatoid arthritis (RA). Conversely, up to 86% of patients suffering from RA have cervical spine involvement with most of them involving the upper cervical region and CVJ. The progn...
Article
Knowledge of normal biomechanics of the cervical spine is very important as it can be modified by various pathological situations. The changes that occur during injury and/or in consequence with other pathological conditions or surgical procedures can substantially influence the stability of this most important spinal joint-ligamentous complex. The...
Article
Paragangliomas are benign neuroepithelial tumours typically localized in glomus caroticum and jugulare. Their spinal localization is very rare, entirely in the area of cauda equina and filum terminale. We present a case report of 33-year old woman. Her initial symptom was low back pain irradiating into lower limbs without neurological deficit. Magn...
Article
Intramedullary astrocytoma is one of the less common tumours of the central nervous system. Certain ambiguities in the literature led us to make a retrospective review of a series of our own (2003-2009) and to compare the results with available literature. This series comprised 15 patients (10 women, 5 men), mean age 42.6 years. According to the Mc...
Article
Malignant peripheral nerve sheath tumor (MPNST) is a highly malignant tumor of the peripheral nervous system, which is likely to reccur locally or metastatize. Its incidence is higher in patients with neurofibromatosis type 1 (NF-1). We present two case reports of patients with this rare tumor. First patient, 74-year old woman, underwent routine ch...
Article
The most frequent procedure used in the Czech Republic for the closure of acquired calvarial bone defects (cranioplasty) uses the modelling of an acrylic implant, which solidifies gradually, into the desired shape directly in the theatre on the basis of the surgeon's estimate. However, even minor inaccuracy in an implant modelled this way may have...
Article
Chordomas are locally invasive, malignant bone tumors that rarely occur in the cervical spine. En bloc resection or even fully resecting the tumor along its margin offers improved patient survival and a potential disease cure. Complete resection of tumors involving the upper cervical vertebrae requires a combined anterior–posterior approach but is...
Article
Intramedullary ependymomas are the most common spinal cord tumors in the cervical and thoracic regions in adult patients. These tumors are benign, slowly growing lesions which are optimally treated with the total surgical resection without adjuvant therapy. The authors have analysed retrospectively a group of eight patients treated within 2001-2004...
Article
Central neurocytoma is a rare brain tumor predominantly encountered among young patients typically localized close to the foramen of Monro and septum pellucidum. In the absence of atypical histology, the prognosis after complete resection is usually excellent. We present a case of a 30 years old man with mild hemiparesis which led to the diagnosis...
Chapter
The anterior screw fixation of odontoid fractures is nowadays standard clinical operation. There are less biomechanical studies dealing with the problem whether one or two screws should be used for this type of stabilisation. This study used in vitro experiment and finite element simulation to investigate the bending stiffness in the sagital plane...
Article
To evaluate surgical management of the fracture of the ring of axis (FRA), known as "hangman's fracture", and to discuss adequacy of this treatment. Between 1994 and 2004, 41 patients with FRA were surgically treated in our hospital. We present a retrospective study of 30 cases treated by anterior cervical fixation and fusion and 11 cases treated b...

The purpose of this prospective semi-randomised comparative study was to compare fusion rates, course of fusion, and occurrence of collapse and subsidence of autologous and allogenic bone grafts in instrumented anterior cervical fusion. The number of fused levels and the smoking status were investigated as potential factors influencing the bone-hea...
Article
This prospective study with minimal 3-year follow-up was performed to compare fusion rates, course of fusion, collapse incidence and occurrence of subsidence in one- and two-level instrumented anterior cervical fusions (ACDF) and thus to proof the hypothesis that use of internal fixation decreases the risk of non-union in bi-segmental ACDFs to the...
Article
Cervical open door laminoplasty has been used for over 20 years. We operated 20 patients (16 men, 4 women) with cervical spinal myelopathy (CSM) and 6 patients with relative cervical spinal canal stenosis due to intramedullary expansion process since March 1999 to December 2002 (46 months). All these patients underwent the bilateral hinge French-do...
Article
A case report. To document our experience with single stage decompression and fixation in the treatment of pyogenic osteomyelitis of the odontoid process. Although several investigators have reported a handful of these unusual cases, up until now, there have been no studies concerning a single stage solution in the surgical treatment of this pathol...
Article
Pure traumatic bilateral lumbosacral dislocation is a rare injury with just eight cases reported in the literature. This condition occurred also in 36-year-old man, who was struck into the lower back by a falling tree, during a woodcutting, at the moment when he was kneeling and his spine was flexed. Neurological examination showed no signs of spin...
Article
Stroke incidence and therapy represents still a major problem. Accomplishment of the functional stroke programme is a necessary goal for the improvement of present unfavourable results of statistics (the third most frequent cause of death, high morbidity). Since 1998, according to the recommendations of the Ministry of Health of the Czech Republic...
Article
To examine the exact position of screws in anterior cervical fusion that were intended to be bicortically anchored at the time of surgery. A randomly selected, representative sample (26) of our patient series undergoing anterior cervical fusion with bicortical screw fixation (250) during period of 1993-1999 is reviewed in this study with respect to...
Article
Intervertebral disc herniation lateral to the intervertebral foramen (far lateral disc herniation, FLH) usually causes compression of the neural root superior to the respective intervertebral space. Insufficient diagnosis and localization of this specific type of herniation may lead to inadequate surgical treatment. If FLH is found to be the cause...
