Surgical treatment of craniocervical junction pathology has evolved considerably in recent years with the implementation of short fixation techniques rather than long occipito-cervical fixation (sub-axial). It is often difficult and sometimes misleading to determine the particular bone and vascular features (high riding vertebral artery, for instance) using only the conventional images in three...
متن کاملAbsence of the odontoid process with atlanto-axial subluxation; anaesthetic aspects.
Anaesthesia in patients with an unstable atlanto-axial joint is fraught with hazards.' Manipulation of the neck during intubation may lead to considerable subluxation in both flexion and extension movements, with pressure from the vertebral body and the odontoid peg. This can significantly reduce the sagittal diameter of the cervical cord, with the possibility of transient or even permanent neu...
متن کاملAtlanto-Axial Instability in Adults with Down's Syndrome
A survey was performed on the patients with Down's syndrome living in three long-stay hospitals for the mentally handicapped in Bristol. Each patient had a chromosomal analysis, lateral X-rays of the cervical spine in flexion and extension and subsequent measurement of the atlanto-odontoid distance, and a neurological examination. Out of a total of 59 patients, with ages ranging from 23 to 65 y...
متن کاملSurgical stabilization of the atlanto-occipital overlap with atlanto-axial instability in a dog.
The atlanto-occipital (AO) overlap in combination with atlanto-axial (AA) instability was found in a dog. We hypothesized that ventral fixation of the AA junction can stabilize the atlas and prevent AO overlap by reviewing our past cases with AA instability. A standard ventral fixation of the AA junction using stainless k-wires and polymethyl methacrylate (PMMA) was performed. The dog fully rec...
متن کاملChronic Atlanto-Axial Instability in Down Syndrome*f
We studied the radiographs of thirtytwo patients with Down syndrome for evidence of atlanto-axial instability. One of the patients had instability in 1970 and seven had it in 1983. The interval between the atlas and the odontoid process in the patients who demonstrated motion at that interval radiographically averaged 2.78 millimeters in 1970 and 6.93 millimeters in 1983 (p < 0.005). Four patie...
