【摘要】：目的尸體標(biāo)本實(shí)驗(yàn)中比較新型導(dǎo)絲和傳統(tǒng)導(dǎo)絲的生物力學(xué)特征,并通過(guò)臨床實(shí)驗(yàn)分析新型導(dǎo)絲的安全性和有效性。方法通過(guò)尸體標(biāo)本比較新型導(dǎo)絲和傳統(tǒng)導(dǎo)絲從腰1椎體至腰5椎體的平均推力和需要穿透椎體前壁的力量。結(jié)果對(duì)新型導(dǎo)絲的推力導(dǎo)致導(dǎo)絲尖端螺旋部分在椎體內(nèi)彎曲或散開(kāi),從而阻止導(dǎo)絲向椎體前方移動(dòng),新型導(dǎo)絲和傳統(tǒng)導(dǎo)絲平均的推力分別為(15.5±1.9)和(5.7±0.8)牛頓(P0.001),新型導(dǎo)絲和傳統(tǒng)導(dǎo)絲穿破椎體前壁的平均推力分別為(69.1±4.2)和(37.1±4.8)牛頓,(P0.000 5),在使用的222根新型導(dǎo)絲的臨床實(shí)踐中無(wú)導(dǎo)絲穿破椎體前壁的現(xiàn)象。結(jié)論新型導(dǎo)絲在椎體內(nèi)的平均推力和需要穿透椎體前壁的力量為傳統(tǒng)導(dǎo)絲的2~3倍,新型導(dǎo)絲可有效阻止導(dǎo)絲在椎體內(nèi)向前方移動(dòng)并防止導(dǎo)絲穿透椎體前壁,新型導(dǎo)絲可有效提高合并骨質(zhì)疏松患者接受經(jīng)皮置釘手術(shù)的安全性。
[Abstract]:Objective to compare the biomechanical characteristics of new wire and traditional wire in cadaveric specimens, and to analyze the safety and effectiveness of new wire. Methods the average thrust of the new type of guide wire and the traditional guide wire from the lumbar vertebra to the lumbar 5 vertebrae and the force needed to penetrate the anterior wall of the vertebral body were compared with the cadaveric specimens. Results the thrust of the new guide wire caused the helical part of the tip of the guide wire to bend or disperse in the vertebral body, thus preventing the guide wire from moving to the front of the vertebral body. The average thrust of the new guide wire and the traditional guide wire were (15.5 鹵1.9) and (5.7 鹵0.8) Newton (P0.001), respectively. The average thrust of the new guide wire and the traditional guide wire through the anterior wall of the vertebral body was (69.1 鹵4.2) and (37.1 鹵4.8) Newton, respectively (P0.0005). The phenomenon of a wire piercing the anterior wall of the vertebral body. Conclusion the average thrust of the new guide wire in the vertebral body and the force needed to penetrate the anterior wall of the vertebral body are 2 or 3 times that of the traditional guide wire. The new type of guide wire can effectively prevent the guide wire from moving forward in the vertebral body and prevent the guide wire from penetrating the anterior wall of the vertebral body. New wire guide can effectively improve the safety of percutaneous nail placement in patients with osteoporosis.
