This paper discribed the methods by which the equine and bovine radiographs of coxofemoral joints and the proximal one third of the femur was projected with ventrodorsal projection and the method of restraint for the radiography was made. All the view of coxofemoral joints and the view in part of the proximal one third of the femur could be achieved by the ventrodorsal projection and the method of restraint. The pneumography of coxofemoral joints had been intensifyed the contrast of the articular view and had...

This paper discribed the methods by which the equine and bovine radiographs of coxofemoral joints and the proximal one third of the femur was projected with ventrodorsal projection and the method of restraint for the radiography was made. All the view of coxofemoral joints and the view in part of the proximal one third of the femur could be achieved by the ventrodorsal projection and the method of restraint. The pneumography of coxofemoral joints had been intensifyed the contrast of the articular view and had been shown the anatomical sign of the coxofemoral bursa. The application of the pneumography might proffered aclear dependence for the examinaion of the lesion of coxofemoral joints. This paper also described that following the radiogaphy taken by described method for three cases of femoral fracture in the horses and cattle, diagnosis had been accomplished.

本文叙述了马、牛髋关节及股骨上段1/3 X线腹背位投照方法,以及为X线摄影而采取的保定方法。应用这种腹背位投照方位和保定措施能获得马,牛髋关节影像的全貌以及股骨上段1/3部分的影像。髋关节充气造影术增加关节影像的对比度,并显示出髋关节囊的解剖征象。应用充气造影对检查髋关节损伤可提供明确的依据。

This paper deals with three cases of long jumpers suffering from fracture at middle one-third of the femoral shaft. This kind of fracture is transverse and produced by indirect force at the landing moment. This is a characteristic fracture which we call a jumping femoral fracture.Physical examination reveals swelling with tenderness and deformity of the injured thigh. X-ray shows a transverse fracture and angulating deformity at middle one-third femoral shaft in all cases.Two cases were performed...

This paper deals with three cases of long jumpers suffering from fracture at middle one-third of the femoral shaft. This kind of fracture is transverse and produced by indirect force at the landing moment. This is a characteristic fracture which we call a jumping femoral fracture.Physical examination reveals swelling with tenderness and deformity of the injured thigh. X-ray shows a transverse fracture and angulating deformity at middle one-third femoral shaft in all cases.Two cases were performed by open reduction and internal fixation with Küntschcr or medullary nail, and one case was performed by traction through the intercondylus of the lower femur. All patients got good result after one year, but open reduction was better than skeletal traction.According to clinical observations, CT examination of the femur in normal person and experiment of the femoral shaft with fresh cadaver, the mechanism is based on the imbalance of the body rising high into the air, which produces both scissors stress and rotational force at landing. In the meanwhile the posterior group muscles of the thigh were more likely to be relaxed reflectively, leaving the femoral shaft unprotected.

本文报告因跳远训练导致股骨干骨折3例。通过临床观察,正常人股骨干CT值检查,以及新鲜尸体股骨干破坏实验,认为该骨折的发生原理是在跳远运动腾空时,身体失去平衡,在落地的瞬间,一足首先固定于沙坑,躯干剧烈扭转,从而产生剪应力和旋转暴力结合于股骨中部,同时大腿后群肌肉反射性松弛,失去对股骨干的保护作用。近年来我们遇到跳远运动所引起的股骨中1/3处横形或斜横形骨折3例,从发生原因,骨折部位以骨折形状均极相似,我们认为是一种特殊类形的骨折,为了探讨其发病机理,除了临床观察以外,还在正常运动员股骨应用CT检查,以及新解尸体股骨进行CT检查和力学破坏试验。

With the use of modern photomechanical methods and the 3-D photoelastical frozen methods, the stress, the strain and displacement of proximal femur were studied and several significant results obtained. These results will not only provide practical basis for clinical cure, but also be significant to the device of properform, high strength and good toughness of man-made bone. Based on the results of femoral fracture, the interfixer was presented andits mechanical damage to the bone tissue was also evaluated....

With the use of modern photomechanical methods and the 3-D photoelastical frozen methods, the stress, the strain and displacement of proximal femur were studied and several significant results obtained. These results will not only provide practical basis for clinical cure, but also be significant to the device of properform, high strength and good toughness of man-made bone. Based on the results of femoral fracture, the interfixer was presented andits mechanical damage to the bone tissue was also evaluated. Furthermore, in orderto find out an effective way to treat the fracture af femoral neck, the destructivetest was carried out, the destructive forms of the bone Were observed, and thefunction of interfixer was discussed. Meanwhile, an ideal porous material was developed to analogize the propertiesof femoral bone. The elastic properties of this ideal material can be used to describethe constitutive equations of the femoral bone.

本文应用现代光测力学法及三维光弹冻结切片法等,对股骨上端进行了应力、应变和位移分析,得到了有价值的结果。这些研究除直接对临床医疗提供依据外,还对设计出形状合理、强度高、韧性又好的人造骨,具有重要的指导意义。在实验研究的基础上,本文对股骨颈骨折治疗及对骨组织的损伤作了探讨。并对防腐骨进行了破坏试验,观察了破坏现象及破坏形式。同时还较深入的探讨了目前有代表性的三种内固定器治疗法的功效, 最后,提出了一种理想的多孔材料来模拟股骨材料性质,借用这种材料的性质来描述股骨上端骨材的本构方程。
