The Early Effect Evaluation Of Single-Bundle Reconstruction Of Anterior Cruciate Ligament With Dual-Source Computed Tomography

Objective.The purpose of this study was to discuss the early effect evaluation of single-bundle reconstruction of anterior cruciate ligament with dual-source computed tomography and the clinical application value.Methods. Dual-source computed tomography (DSCT) scanning was performed in fifty cases of single-bundle reconstruction of anterior cruciate ligament from July 2014 to February 2015,including thirty-four males and sixteen females, to obtain images of Three-dimensional reconstruction of the Lateral condyle of femoral, the tibia platform,the graft of anterior cruciate ligament, reproducing the natural mark and tunnel of anterior cruciate ligament. Then we could measure the center position of bone tunnel,and observe morphology of the graft.Results. The tibia bone tunnel center position is:in the sagittal plane, the center of bone tunnel is 48%;in the coronary plane, the center of bone tunnel is 51%.the center of the femoral tunnel accounted for 20% of the femoral condyle height from the proximal to distal, In the line of Blumensaat level accounted for 25% of the length of the lateral femoral condyle from backward to forward. The cases of ACL graft impacted on fossa intercondyloidea is two,forty-eight cases have appropriate morphology.Conclusions. Dual-source CT can clearly show the location of the bone tunnel and graft after ACL reconstruction and can be used in the clinical postoperative assessment of ACL reconstruction in comparing the relationship between tunnel and nature mark of ACL, so as to guide the performer to improve surgical skills.
