In the current study, in a survey of 4121 double contrast radiographs of the colon performed from 1987 through 1995, the hip joints were examined and classified with regard to the presence or absence of primary coxarthrosis. The data collection was performed in precisely the same manner as in two earlier studies undertaken on 3903 radiographs of the colon covering the years 1956 through 1962 and 4027 radiographs of the colon covering the years 1975 through 1982. In the current study the prevalence of coxarthrosis, the gender ratio, and distribution between bilateral and unilateral cases had not changed compared with the data from the two earlier studies. When pooling the three investigations, the age specific prevalence of primary coxarthrosis based on the 12,051 radiographs fits an exponential curve for which the prevalence of primary coxarthrosis increased from below 1% in the age group younger than 55 years to 10% in the age group older than 85 years. In the current study approximately half of the patients (55%) had undergone total hip arthroplasty. This was more than in the study from 1984 (35%). Among the surgically treated patients, lateral coxarthrosis was more common than was medial coxarthrosis.
在当前研究中，对1987年至1995年期间进行的4121例结肠双重对比X线片进行了调查，检查髋关节并根据是否存在原发性髋关节病进行分类。数据收集的方式与之前两项研究完全相同，前一项研究涉及1956年至1962年期间的3903例结肠X线片，后一项研究涉及1975年至1982年期间的4027例结肠X线片。与两项早期研究的数据相比，当前研究中髋关节病的患病率、性别比以及双侧和单侧病例的分布没有变化。将三项调查汇总后，基于12,051张X线片得出的原发性髋关节病的年龄特异性患病率符合一条指数曲线，即原发性髋关节病的患病率从55岁以下年龄组的低于1%增加到85岁以上年龄组的10%。在当前研究中，大约一半的患者（55%）接受了全髋关节置换术。这一比例高于1984年的研究（35%）。在接受手术治疗的患者中，外侧髋关节病比内侧髋关节病更常见。
