| Objective:Cervical anterior cervical artificial between disc replacement surgery inmy carried out yilai after constantly of efforts get has gradually of development,technology increasingly mature, surgery volume gradually increases, but currentlydomestic application of artificial neck disc also is not achieved localization, are is fromEurope imports, and imports of cervical artificial between disc and no for Chinesedesign of artificial between disc fake body, due to people and Europe people comparedto neck disc exists deliberately of physiological Anatomy structure, such not onlyeffects has surgery in the artificial between disc model of select, And that causepostoperative recovery in patients with less desirable effects, is intended to measure,this study analyses of normal Chinese neck cervical73-disc diameter (width), sagittaldiameter (depth) as well as the upper and lower end plates maximum clearance (height),for reference for the Chinese designed cervical artificial disc model.Methods:Select Dalian Medical University subsidiary first hospital July2013-September2013images section all line cervical CT key sweep patients more than700over cases, from pick cervical CT scan is not see exception lesions of normal total80cases, which male40cases (50%), female40cases (50%), male age18-61age,average38.8±13.2age, female age22-60age, average age41.8±12.3age, all patientsaverage age40.4±12.7age. Measurement key sweep of cervical spine CT, firstaffiliated hospital of Dalian Medical University Radiology EDS CT, scanningconditions are2mm for each layer, each layer from0.4mm. Coronal measurements to size (width), sagittal diameter (depth) and the upper and lower end plates height up tothe base, using computer reading software to measure its C3-4, C4-5, C5-6, C6-7disc-shaped trail (width), sagittal diameter (depth) and upper and lower end platesheight maximum height (altitude), statistics and data analysis.Results:In all normal in the40cases male information for C3-4between discCrown shaped trail size interval about for13.7-16.5mm; vector shaped trail size aboutfor14.4-18.5mm; height about for4.5-7.1mm,C4-5between disc Crown shaped trailsize about for14.1-17.2mm; vector shaped trail size about for14.8-18.7mm; heightabout for3.6-7.4mm;C5-6between disc Crown shaped trail size about for15.1-18.5mm;vector shaped trail size about for13.9-18.2mm; height about for4.3-7.9mm;C6-7between disc Crown shaped trail size about for16.0-18.8mm; sagittal diameter isapproximately14.1-18.3mm; height is about5.0-8.4mm.40cases female informationfor C3-4between disc Crown shaped trail size about for12.0-15.2mm; vector shapedtrail size about for13.4-16.4mm; height about for4.2-6.8mm;C4-5between disc Crownshaped trail size about for12.7-15.8mm; vector shaped trail size about for12.9-16.0mm;height about for3.7-6.7mm;C5-6between disc Crown shaped trail size about for13.3-16.3mm; vector shaped trail size about for12.7-16.3mm; height about for3.6-6.7mm;C6-7between disc Crown shaped trail size about for13.9-17.2mm; vectorSize is approximately13.5-17.1mm; height is about4.1-7.1mm.
