Material and MethodsRA Rabbit Model group: 15 early RA rabbits of the same weight and variety Control group:10 normal rabbits of the same weight and varietyMethods of making RA rabbit model:elect 15 normal rabbits of the same weight and variety, dissolve Ovalbumin in 0.9% sodium chloride solution, to make the solution of 20mg/ml concengtration, blend the same quantity of complete Freund′s Adjuvant equably ,inject the mixed solution into endermic tissue of the rabbit′s scapular section, making the rabbits allergic, inject 1 ml of the mixed solution to one rabbit every time, inject 1 ml of the mixed solution in 5 different places of the rabbit′s scapular section, inject the rabbit one time every week,inject 3 weeks continuously,it turned out to be that the rabbits will be allergic, inject Ovalbumin blent with the 0.9% sodium chloride solution into the knee joint cavity of the rabbits in the fourth week, 5 mg Ovalbumin every knee joint cavity,two knees of every rabbit of the 15 rabbits are both injected,the arthrosis diameter and the exterior temperature of the knees will be added obviously in 24 hours,and they will drop gradually,at the time of the 14th or 21th day, the arthrosis diameter and the exterior temperature of the knees will get to the balance time,the incidence rate of RA is 100%.after the RA model succeeds,it is the early time of RA from the first week to the fourth week,after the fourth week,it is the late time of RA, the cartilage of the femoral condyle and the subchondral bone cortices will be changed unrecoverily.

资料与方法RA模型组：早期RA家兔模型15只，品种及体重接近。对照组：正常家兔10只，品种及体重接近。RA家兔模型制作方法：选取15只成年家兔，体重、品种接近，将卵蛋白溶解于生理盐水，配成浓度为20mg/ml的溶液，与等量完全弗氏佐剂混匀，注入家兔肩胛区皮下致敏，每只家兔每次注射1ml，于肩胛区5个不同区域注射，每周一次，连续注射3周而致敏，第4周向膝关节腔注射卵蛋白生理盐水溶液，每只关节腔注射5mg卵蛋白，15只家兔膝关节全部注射，24h内此关节直径和表面温度大幅度上升，以后缓慢下降，至14～21d达到平台期，发病率达100%。造模成功后第1～4周为早期改变，第4周以后出现不可逆的关节软骨及骨破坏。采用高频超声对RA模型组与对照组的膝关节髌上囊液体厚度、滑膜及股骨髁软骨厚度及软骨下骨皮质的回声情况进行对比观察。结果RA组模型组膝关节髌上囊积液及滑膜的厚度明显厚于对照组，其股骨髁软骨的厚度与对照组相比无明显差异，其软骨下骨皮质与对照组相比无明显改变。

2The fixation with the flexion angle of 90°in the supinator position is adopted if the Jateral side presents, displacement and medial periostenm is broken and the"hinge"of the lateral periosteum remained unbroken.

本研究从生物力学角度探明肱骨髁上部的力学特性，并提出合理的固定方法，为治疗肱骨髁上骨折，预防肘内翻提供了理论依据，具有重要的临床意义。

Objective: To summarize the clinical experience of retrograde intramedullary supracondylar nail in the treatment of type C femoral intercondylar fracture.

RESULTS:①MRI scanning from coronal section: after 10 mL contrast-medium injection, in the center of medial knee joint, high visual signal was seen in the cavity of joint; after 15 mL contrast-medium injection, scanning between femora and patella, high visual signals were observed; after 20 mL contrast-medium injection, scanning by posterior internal and external condyle of knee, high visual signals were found in 80% of internal and external recess of posterosuperior of thighbone.

结果：①在膝关节冠状面MRI扫描：注入10 mL对比剂时，经膝关节内侧中点处，关节腔内均可见高信号；注入15 mL对比剂时，经股骨和髌骨间，关节腔内均可见高信号；20 mL对比剂时，经股骨内、外侧髁后缘处，80%股骨后上内、外侧隐窝内出现高信号。

Of the femoral fracture,there were 14 cases of fractures of shafts of femurs and 1 case of supracondylar fracture of femur;11 male, 4 female;7 left cases,8 right cases;1 case complicated with bending of bone plate and screw,6 cases with breakages of plate;1 case with bending of common intramedullary nail,2 cases with breakages of common intramedullary nails,1 case of screw and wire lock fixation complicated with pseudoarticulation formation,4 cases with nonunion of fracture.
