【摘要】： 實驗目的: 本文目的基于進行下頸椎椎弓根的相關經(jīng)線及角度測量,定位更準確的椎弓根進釘點、置釘方向,為成功應用經(jīng)頸椎椎弓根螺釘技術提供必要信息。 實驗方法: 1、在27具中國成人干燥頸椎標本上,用游標卡尺、角度測量器對椎弓根高度(PH )、寬度(PW )、椎弓根軸線的骨性通道全長(TL)、兩種椎弓根長度(PL1,PL2)。 2、在下頸椎CT圖像上測量椎弓根高度(PH′)、寬度(PW′)、椎弓根軸線的骨性通道全長(TL′)、兩種椎弓根長度(PL′1,PL′2)、椎弓根松質骨高度(PSH)、椎弓根松質骨寬度(PSW )、椎弓根橫斷面角(PTA )、椎弓根矢狀面角(PSA )、椎弓根斷面松質骨比例(PS)、椎弓根斷面皮質骨比例(PC)等具有臨床意義的數(shù)據(jù)進行測量。比較標本測量及CT測量的數(shù)據(jù),是否具有統(tǒng)計學差異。 3、選福爾馬林浸泡的標本9具,按照測量結果及文獻報道的進釘點置釘,判斷置釘效果。, 實驗結果: 1.大體標本椎弓根最窄處高度(PH )、椎弓根最窄處寬度(PW )、椎弓根軸線的骨性通道全長(TL)及兩種椎弓根的長度(PL1、PL2)結果見表1。 2.CT圖像上測量椎弓根高度(PH′)、寬度(PW′)、椎弓根軸線的骨性通道全長(TL′)、兩種椎弓根長度(PL′1,PL′2)結
[Abstract]:Objective:Objective based on the relative meridian and angle measurement of the pedicle of the lower cervical vertebrae, to locate the more accurate point of pedicle screw and to provide the necessary information for the successful application of the technique of transpedicular screw.Experimental methods:1. In 27 dry cervical vertebrae specimens of Chinese adults, the height of pedicle was measured by Vernier caliper, the width of PW, the total length of bony passage of pedicle axis, and the length of pedicle of two kinds of pedicle were measured by Vernier caliper and angle measuring instrument.2. On CT images of lower cervical vertebrae, the height of pedicle and the width of pedicle were measured. The length of bony passage in the axis of pedicle was TLX, the length of pedicle of two kinds of pedicle was 1 PL2, the height of cancellous bone of pedicle was PSH1, and the width of cancellous bone of pedicle was PSW.The clinical data of PTA, PSA, PSV and PCP of pedicle cross-sectional angle, sagittal angle of pedicle, and ratio of cortical bone of pedicle cross-section were measured.Compare the data of specimen measurement and CT measurement, whether there is statistical difference.3. 9 specimens soaked in formalin were selected to judge the effect of nail placement according to the results of measurement and the report of literature.Experimental results:1.The height of the narrowest part of the pedicle, the width of the narrowest part of the pedicle of the pedicle, the full length of the bony channel of the pedicle axis (TLL) and the length of the pedicle of the two kinds of pedicle are shown in Table 1.The height of pedicle and the width of pedicle were measured on 2.CT images. The total length of bony passage in the axis of pedicle and the length of pedicle of two kinds of pedicle were measured.
