Around Atlantoaxial Joint Relations And Clinical Significance Research

The clinical surgery regional anatomy research's progress and the phantom study development, much more attentions were payed to atlanto-axial joint instability .Objectives: It was studied 57 atlanto-axial instability cases associating clinic and imageology in two years from 2006.3 to 2008.3. The X-ray,CT and MRI inspection provided the basic reference opinions about value of diagonosis treatment of atlanto-axial instability cases.Methods: Injured patients of cervical spine was cayyied on X-ray inspection.,then according to the result of ADI and LADS ,next to CT or MRI inspection ,and that was to guide clinical diagonosis and treatment.To observe atlanto-dental interval (anterior arch of atlas posterior border to odontoid process anterior border) and odontoid process caster(included angle between axis of ordinate of odontoid process and axis of ordinate of odontoid vertebra) on the X-ray lateral projection.Results:To the cases of ADI widen (was bigger than 3mm) and LADS widen (was bigger than 6.9mm) cayyied on CT scanning, feasible neck surroundings nothing bone structure injure and ligamentum fracture waiting to be not operation treat. Otherwise considered the axis and atlas fusion surgery or the pulvinar neck fusion technical according to extent of damage and type formulating surgery plan .Conlusions: X-ray inspection was routine method of the cervical part injure . Integrating CT(especially three diamensions reconstitution) and MRI can work out the reasonable therapeutic program. It could understand the circumstance of the atlanto-axial joint surroundings ligment structure, in order to draw up reasonable of treatment project.
