Blocks of the Trunk and Perineum
1988
Intercostal nerve block was derived from thoracic paravertebral block. Its origin can thus be traced to the beginning of the century (see Sect. VII. B).
Anatomic variation of the vertebral artery

Applied Anatomy of the Cerebral Arteries
1991
Four arteries supply the brain with blood: the two carotid and the two vertebral arteries. Although these four vessels are ultimately interlinked via a basal arterial network, the circle of Willis, and anastomoses at the brain surface, Heubner’s anastomoses, it is useful to distinguish anterior (carotid anterior and middle cerebral) and posterior (vertebrobasilar posterior cerebral) vascular territories (Gillian 1957, 1968; Lazorthes 1961; Kaplan and Ford 1966; Ganshirt 1972; Seeger 1978; Dorndorf 1983; Duus 1983).
Ossovenography and Epidural Venography
1976
Henning (1940) and Ehrhardt and Kneip (1943) were the first to report injection of contrast medium into bone. In 1952 Fischgold et al. reported that contrast injections into a human spinous process resulted in an outline of the venous plexus of the attached vertebral body. In subsequent years improvements have been made which now permit contrast visualization of the venous plexuses of the entire vertebral axis.
Financial Aspects of Cervical Disc Arthroplasty: A Narrative Review of Recent Literature
2020
Recently, there has been significant interest in understanding the cost-effectiveness of treatments in spine surgery as health care systems in the United States move toward value-based care and alternative payment models. Previous studies have shown comparable outcomes of cervical disc arthroplasty (CDA) and anterior cervical discectomy fusion; however, there is a lack of consensus on the cost-effectiveness of CDA to support full adoption. Evidence of the limitations of these cost-analysis studies also exists in the literature, including industry funding, potential selection bias, and varying methods of calculating value. The goal of this narrative review is to provide an overview of the co…
I GESTI MOTORI NELLE SCOLIOSI MINORI
2008
Per scoliosi s'intende una deviazione laterale permanente della colonna vertebrale, che si accompagna ad alterazioni anatomiche delle vertebre e delle altre strutture di sostegno del tronco. La Scoliosis Research Society definisce la scoliosi come una curva (> 10 gradi Cobb) sul piano frontale che si manifesta con un'inclinazione laterale, che comporta l'allontanamento di un certo numero di vertebre dalla linea mediana; questa modificazione dà origine ad una curva laterale, caratterizzata da un apice, essendo la vertebra apice la più scostata dall’ asse mediano, e da vertebre neutre o vertebre limite, alle estremità della curva, dove le articolazioni intervertebrali ritornano verso la linea…
The Role of 3D-Printed Custom-Made Vertebral Body Implants in the Treatment of Spinal Tumors: A Systematic Review
2022
In spinal surgery, 3D prothesis represents a useful instrument for spinal reconstruction after the removal of spinal tumors that require an “en bloc” resection. This represents a complex and demanding procedure, aiming to restore spinal length, alignment and weight-bearing capacity and to provide immediate stability. Thus, in this systematic review the authors searched the literature to investigate and discuss the advantages and limitations of using 3D-printed custom-made vertebral bodies in the treatment of spinal tumors. A systematic literature review was conducted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement, with no limits in terms …
Proximal vertebral artery surgery. Results of treatment of ischemia of the rhombencephalon (hindbrain). Simultaneous carotid and vertebral artery dec…
2022
Surgical treatment of hindbrain ischemia is becoming the accepted surgical procedure in cases of stenosis of extracranial segments of vertebral arteries in the course of advanced atherosclerotic lesions in their initial segments (V1) or caused by external compression of these arteries in the canal formed by the transverse processes of cervical vertebrae. The latter is referred to as vertebrobasilar insufficiency (VBI). The transposition of the left vertebral artery to the common carotid artery in cases where stent graft implantation is necessary with coverage of the subclavian artery and possible blood supply disorders of both the hindbrain and the spinal cord has become important. In the D…
ASSESSMENT AND REHABILITATION PROGRAM IN DIZZINESS PATIENTS PRESENTING VERTEBRAL FRACTURE
2021
Vertebral fragility fractures, usually occurring in elderly people affected by osteoporosis, due to bones resistance alteration, produce balance disorders [1].Balance is the correct connection between the subject and the surrounding environment [2]. Neuro-physiological, biomechanical, emotional, psychological and relational factors have an important influence in posture assessment and balance maintenance, because of the universally recognized role of “polisensorial system.” A preferential motor-sensorial strategy is always present with possibility of readaptation during life, especially after a central or peripheral injury, establishing neuro-plastic processes and compensation mechanisms to…
