摘要
目的 :通过CT测量 ,使用TEA(TransepicondylarAxis ,TEA )作为股骨远端的标志来检测青少年髌股关节紊乱时的下肢排列和股骨远端形态。材料与方法 :选用 3组病人。脱位组 :2 6例病人共 3 9个膝关节 ;膝前痛组 :43例共67膝 ;对照组 :12例 2 4膝 ,。对各组病人均行股骨颈、股骨远端、胫骨近、远端的CT检查。得到以TEA为基准的股前倾角、前髁角和后髁角以及膝旋转 ,同时测量常用的髁角、髌骨倾斜角及胫骨旋转等。结论 :发现脱位组后髁角有显著增大 ,内、外侧付韧带的股骨附着点有异常改变 ,进而TEA发生外旋。本研究是在同类研究中首次使用TEA作为新的标志。
Objective: To assess the 3 dimensional alignment and the morphology of the distal end of femur in juvenile patellofemoral disorders by CT using TEA (Transepicondyle Axis) as a landmark of the distal femur.Methods:Patients were divided into three groups.Dislocation group consisted of 39 knees in 26 patients who had an episode of patellar dislocation once or more times.Anterior knee pain group consisted of 67 knees in 43 patients who had an anterior knee pain without episode of patellar dislocation.Control group consisted of 24 knees in 12 patients who had no symptom around knee.CT images of femoral neck,distal femur,proximal and distal tibia were obtained.Results and Discussion:It was found that the posterior condyle angle in dislocation group was increased significantly,and the femoral insertion of the bilateral collateral ligaments were altered.The above changes resulted in the external rotation of TEA.This is the first study using TEA as a landmark in researchs concerning recurrent patellar dislocation.
