【摘要】：目的：探討雙源CT評(píng)價(jià)膝關(guān)節(jié)鏡下前交叉韌帶單束重建術(shù)后早期效果及其臨床應(yīng)用價(jià)值。方法：對(duì)2014年7月——2015年2月我院收治的50例(其中男34例,女16例)關(guān)節(jié)鏡下前交叉韌帶單束重建患者于術(shù)后第二天行雙源CT掃描。使用CT圖像后處理工作站三維重建膝關(guān)節(jié)股骨外髁、脛骨平臺(tái)三維模型,重建ACL移植物,再現(xiàn)ACL自然印記及骨道位置,測(cè)量骨道中心點(diǎn)相對(duì)位置,觀察移植物走行。結(jié)果：脛骨骨隧道中心點(diǎn)位置為：矢狀面上,骨隧道中心點(diǎn)相對(duì)位置為48%；冠狀面上,骨隧道中心點(diǎn)相對(duì)位置為51%。股骨骨隧道中心點(diǎn)位置為：由近到遠(yuǎn)股骨髁高度的20%,在Blumensaat線水平由后向前方向股骨外髁長度的25%。ACL移植物走向良好并與髁間窩無撞擊的有48例,發(fā)生撞擊的有2例。結(jié)論：雙源CT三維重建能夠清晰地顯示ACL股骨、脛骨骨隧道位置,再現(xiàn)ACL移植物的走向,可用于臨床評(píng)估術(shù)后骨隧道與移植物位置關(guān)系,對(duì)臨床ACL重建術(shù)后效果評(píng)估具有很好的指導(dǎo)意義。
[Abstract]:Objective: to evaluate the early effect of single-bundle reconstruction of anterior cruciate ligament (ACL) under knee arthroscopy by dual-source CT and its clinical value. Methods: from July 2014 to February 2015, 50 cases (34 males) were treated in our hospital. Sixteen female patients underwent dual-source CT scanning on the second day after arthroscopic reconstruction of the anterior cruciate ligament. Three-dimensional reconstruction of the lateral femoral condyle and tibial plateau of the knee joint was performed with a post-processing workstation for reconstruction of ACL graft. The ACL natural imprint and the position of bone canal were reproduced, the relative position of the center point of bone passage was measured, and the walking of the graft was observed. The relative position of the center point of the bone tunnel is 51. The central point of the femoral bone tunnel is 20 from the proximal to the distal femoral condyle. At the level of Blumensaat line, 25% of the lateral femoral condyle length from the posterior to the front of the femur moves well, and there is no impact with the intercondylar fossa in 48 cases. Conclusion: the position of bone tunnel of ACL femur and tibia can be clearly displayed by 3D reconstruction of dual source CT, and the direction of ACL graft can be reappeared, which can be used to evaluate the relationship between bone tunnel and graft position after operation. It is of great significance to evaluate the effect of ACL reconstruction.
