“…OO has also been implicated in the development of cerebellar infarction [ 38 ]. Three-dimensional (3D) computed tomographic (CT) angiography showed that atlanto-axial dislocation resulted in the irregular narrowing of the vertebral artery, so the endothelium there is a likely focus for embolus formation [ 39 ].…”

Os odontoideum (OO) is a rare anomaly of the odontoid process first described by Giacomini in 1886. There is considerable debate about the origin of this anomaly, whether congenital or acquired, though a growing body of evidence favors the latter.Using PubMed, we reviewed the literature on OO with regards to its etiology, clinical presentations, diagnostic modalities, and management. Manuscripts cited in reviews were also searched manually.Because the medical literature on this condition is limited, our understanding of the natural history and management of OO is still vague. The management guidelines for asymptomatic OO are preliminary. Therefore, we need more large-center studies to investigate this condition further.

“…The potential profits of using recombinant human bone morphogenetic protein-2 (rhBMP-2) over auto graft or allograft bone are abundant; they may contain reduced operational time, blood loss, donor-site morbidity, transmission of infection because of allograft, and rate of pseudarthrosis (77,78). On junction with adjuvant bone marrow aspiration or biological agents that comprise precursor cells to promote osteogenesis, and in some cases osteo induction, provide the required elements for osseous fusion (68,69,(79)(80)(81)(82)(83).…”

Context: The most common source of cervical spine arthrodesis in the pediatric populace is the instability related to congenital or traumatic damage. Surgery of cervical spine can be challenging given slighter anatomical constructions, fewer hardened bone, and upcoming growth potential and growth. Evidence Acquisition: Trainings in adult patients recommended that consuming screw constructs results in enhanced consequences with inferior amounts of instrumentation catastrophe. But, the pediatric literature is inadequate for minor retrospective series. Authors reviewed the existing pediatric cervical spine arthrodesis literature. They studied 184 abstracts from January 1976 to December 2014. An entire of 883 patients in 82 articles were involved in the evaluation. Patients were characterized as taking either posterior cervical fusion with wiring or posterior cervical fusion with screws or occipitocervical fusion. Results: The etiologies faced most frequently were inherited abnormalities (54%) shadowed by trauma (28%), Down syndrome (8%), and infectious, oncological, iatrogenic, or mixed causes (10%). The mean duration of follow-up was 32.5 months. Conclusions:The consequences of this training are restricted by deviations in construct policy, usage of orthoses, follow-up period and fresher adjuvant produces stimulating fusions. But, a literature review recommend that instrumentation of the cervical spine in children may be harmless and more effective than using screw concepts rather than wiring methods.

“…Patients with atlantoaxial dislocation often report dizziness and vertigo in relation to head movement or positional changes (Vinchon et al, 1995;Wenngren et al, 1998). Other pathology, albeit extremely rare, that predisposes to atlantoaxial instabilty is aplasia of the odontoid proccss (Phillips et al, 1998), in which the vertebral artery is stretched by the subluxation of the atlas and os odontoideum (Lyness andSimeone, 1978: Takakuwa et al, 1994;Sasaki et al, 2000). Arnold-Chiari malformation is a congenital abnormality resulting in tht: herniation of the tonsils of the cerebellum and medulla oblongata through the foramen magnum into the vertebral canal.…”

The Dix-Hallpike manoeuvre is widely used in the diagnosis of positional vertigo and is regarded as safe. The manoeuvre involves a degree of neck rotation and extension, and consequently one might expect there to be some patients, particularly those with neck problems, in whom the manoeuvre is contraindicated. The term 'neck problem', however, encompasses a whole range of conditions, including soft tissue disorders, cervical spondylosis, prolapsed intervertebral disk, and severe rheumatoid arthritis with cervical instability. These in turn will give rise to a variety of symptoms, which will vary from minimal pain or stiffness to severe pain or complete immobility, and, in some cases, neurological deficit. Clarification is therefore needed to establish the point at which any neck pain or stiffness ceases to be a minor problem and becomes a contraindication to performing the Dix-Hallpike manoeuvre. This paper clarifies this issue by discussing the issue of absolute contraindications and proposing a simple functional assessment of neck mobility which can be performed prior to performing the Dix-Hallpike manoeuvre. Relative contraindications such as back pathology, vertebrobasilar ischaemia (posterior circulation ischaemic disease), nerve root compression and medical fitness are also discussed.

Os Odontoideum With Cerebellar Infarction

Abstract: Atlantoaxial instability may cause insufficiency of the vertebral artery as well as spinal cord injury. More attention should be paid to the possible relation between atlantoaxial instability and vertebrobasilar artery insufficiency.
