编辑同志: 常规X线摄片检查髌骨轴位,由于被检者俯卧或侧卧于摄影台上,患侧膝关节需要极度屈曲才能够达到摄影目的。许多患者(尤其髌骨骨折患者)不能做到上述要求。摄影效果不甚理想。为此,笔者经过长期的探索,设计了一种新的髌骨轴位投照法,即中心线向足侧倾斜30°左右投照。经过48例的试验,效果满意,兹介绍如下。 1、体位及片盒摆法:患者仰坐于摄影台一端,双手向后撑于台面之上,头后仰,双下肢自然下垂(以
Editor’s Comrade: Conventional X-ray examination of the patellar axis, as the subject was prone or lying on the stage, the affected knee needs extreme flexion in order to achieve photography purposes. Many patients, especially those with patellar fractures, can not do this. Photographic effect is not ideal. To this end, the author after a long period of exploration, the design of a new patellar axial projection method, that is, the centerline tilted about 30 ° to the left foot shot. After 48 trials, the results are satisfactory, it is introduced as follows. 1, position and box pendulum method: the patient sitting on one side of the camera stand, his hands back up on the table top, head back, the natural lower limbs droop (to
