【摘要】：目的:比較椎體成形術與椎體后凸成形術中骨水泥灌注壓力的動態(tài)變化。方法:1.設計與調試能直接記錄椎體成形術與椎體后凸成形術中骨水泥灌注壓力動態(tài)變化的測量裝置。2.在微機控制電子萬能材料試驗機上以0.25mm/min、40N,0.25mm/min、60N,0.5mm/min、60N各2組共6組進行驗證試驗,得到電壓差與壓力之間的關系。3.將10個椎體標本分成2組:PVP組(A1,A2,A3,A4,A5)、PKP組(B1,B2,B3,B4,B5),在室溫20℃下經一側椎弓根PVP組行椎體成形術而PKP組行椎體后凸成形術,骨水泥灌注量為2.4m L,灌注時間為48s,勻速地進行骨水泥灌注,采用設計的灌注壓力測量裝置記錄骨水泥灌注時的實時動態(tài)壓力。術后椎體行CT檢查,觀察骨水泥在椎體內的彌散分布情況。結果:1.驗證試驗中電壓差與壓力呈線性關系,壓力隨電壓差的增加而變大,F(N)=440×U(V)。2.椎體后凸成形術中丙骨水泥的灌注壓力較椎體成形術中降低。在室溫20℃和推注速度為0.05m L/s下,PVP組第一管骨水泥的平均灌注壓力為12.41±2.42N,最大灌注壓力為19.89±3.82N,第二管骨水泥的平均灌注壓力為19.81±3.03N,最大灌注壓力為33.44±4.86N;而PKP組第一管骨水泥的平均灌注壓力為6.33±2.05N,最大灌注壓力為10.74±3.32N,第二管骨水泥的平均灌注壓力為9.42±1.69N,最大灌注壓力為18.18±1.77N。結論:1.椎體后凸成形術中骨水泥在椎體內灌注壓力較椎體成形術中降低。2.椎體后凸成形術中骨水泥首先填充球囊擴張留下的空腔,灌注壓力較低,彌散情況較椎體成形術中更為均勻,利于降低術中骨水泥滲漏的發(fā)生率。
[Abstract]:Objective: to compare the dynamic changes of bone cement perfusion pressure between vertebroplasty and kyphoplasty. Method 1: 1. Design and debug a measuring device that can directly record the dynamic changes of bone cement perfusion pressure in vertebroplasty and kyphoplasty. In the microcomputer controlled electronic universal material testing machine, the verification tests were carried out in 6 groups with 0.25mm / min 40N / min 40mm / min 60 mm / min 60N and 0.5mm / min 60N, respectively. The relationship between voltage difference and pressure was obtained. Ten vertebrae specimens were divided into two groups: 1 / PVP group (n = 10), A _ (1) A _ (2) A _ (3) A _ (4) A _ (5) P group, B _ (1) B _ (2) B _ (2) B _ (2) B _ (3) B _ (4) B _ (5) B _ (5) PVP group were treated with vertebroplasty at room temperature of 20 鈩，
