Pathologic changes of the sacroiliac joints were observed in 1986 skeletons from dissecting rooms in St. Louis, Missouri and Johannesburg, South Africa. In addition to being the largest population samples ever studied from this standpoint, these samples are the first to include blacks. Para-articular osteophytosis culminating in ankylosis is considered first, followed by the less common intraarticular changes that also occasionally culminate in ankylosis. Expressed as "average involvement" by decade, sex, laterality, and ethnic group, these joint changes are shown clearly to worsen progressively from the age of about 40 years. Osteophytosis especially becomes more common in black males, both American and African Bantu, than in American white males, and generally more common in males than in females. When occurring only (or mainly) unilaterally, the changes average out in favor of the right side, but only slightly. Joint mobility, or lack thereof, is assigned a large etiologic role.
在密苏里州圣路易斯市和南非约翰内斯堡的解剖室中，对1986具骨骼的骶髂关节病理变化进行了观察。从这一角度来看，这些样本不仅是有史以来研究的最大规模人群样本，而且是首批纳入黑人的样本。首先考虑以关节周围骨质增生并最终导致关节强直，其次是较少见的关节内变化，这些变化偶尔也会导致关节强直。按十年、性别、左右侧和种族群体表示为“平均受累情况”，这些关节变化明显显示出从大约40岁起逐渐恶化。骨质增生在美国黑人和非洲班图族男性中比在美国白人男性中更为常见，并且总体上在男性中比在女性中更为常见。当仅（或主要）单侧出现时，变化平均有利于右侧，但幅度很小。关节活动度或缺乏关节活动度被赋予了很大的病因学作用。
