我们在1983年底调查了正在某大桥工地施工的某两个桥梁工程处的潜水员减压性骨坏死情况。现将调查结果报道如下。对象和方法一、X片:用国产200mA X线机,分别对两个桥处24名潜水员(年龄22～55岁,平均36.8岁;潜水工龄5～30年,平均15.5年)进行两肩、髋关节的前后位及两肘、膝关节的正侧位摄片,并要求尽可能多地在片子上显示肱骨和股骨的整个骨干及胫骨的近1/3段。
At the end of 1983, we investigated the diver’s decompressive osteonecrosis of one of the two Bridge Engineering Works who was constructing a bridge site. Now the survey results are reported below. Objects and methods 1. X-ray: 24 domes at two bridges (age 22-55 years, mean 36.8 years; diving age 5-30 years, average 15.5 years) The anteroposterior position of the hip joint and the posterior lateral radiographs of both elbows and knee joints require that as much as possible of the entire 1/3 of the humerus and femur bone and proximal tibia be displayed on the film.
