In a survey of 4027 double-contrast colon roentgenograms, the hip joints were examined and classified with regard to the presence or absence of primary coxarthrosis. The hips were graded according to type and severity of coxarthrosis. The data collection was performed in precisely the same manner as in an earlier study undertaken on 3903 similar examinations that had been performed more than 20 years earlier. During this time period, the prevalence had not changed, nor was there any change in sex ratio or distribution between bilateral and unilateral cases or between types of coxarthrosis. Also, the severity of the coxarthrosis at the time of the examination was approximately the same. A considerable portion of the patients (including those in the present study), about one third, had not been previously diagnosed. In this group, mixed and medial coxarthrosis were more common among men than was lateral coxarthrosis. There was no difference in age or sex between previously diagnosed and undiagnosed groups of coxarthrosis. In the recent study, about one third of the patients had been treated mostly by total hip arthroplasty (THA). In these patients, lateral coxarthrosis was more common. Women were over-represented among the THA cases, even though the coxarthrosis was not more severe.
在一项对4027例结肠双对比X线片的调查中，对髋关节进行了检查，并根据原发性髋关节病的有无进行了分类。根据髋关节病的类型和严重程度对髋关节进行分级。数据收集的方式与20多年前对3903例类似检查进行的早期研究完全相同。在此期间，患病率没有变化，性别比例、双侧与单侧病例之间或髋关节病类型之间的分布也没有变化。此外，检查时髋关节病的严重程度大致相同。相当一部分患者（包括本研究中的患者），约三分之一，此前未被诊断出。在这一组中，男性混合性和内侧髋关节病比外侧髋关节病更常见。已诊断和未诊断的髋关节病组在年龄或性别上没有差异。在最近的研究中，约三分之一的患者主要接受了全髋关节置换术（THA）治疗。在这些患者中，外侧髋关节病更常见。在接受THA治疗的病例中，女性比例过高，尽管髋关节病并不更严重。
