In a series of 33 intertrochanteric femoral fractures in patients suffering from classic rheumatoid arthritis (RA), the typical patient was about 70 years of age, osteopenic, and severely affected by longstanding polyarticular RA of joints other than the hip. Prefracture involvement of the hip joint (other than osteopenia) was apparent radiographically in only 9.1% of patients. There was a higher rate of avascular necrosis (9.7%) and nonunion (6.5%) than expected in the nonrheumatoid general population. There was also a high rate of secondary displacement. Of three patients with avascular necrosis, two had had corticosteroid treatment.
在一组33例患有典型类风湿性关节炎（RA）的股骨转子间骨折患者中，典型患者年龄约70岁，存在骨质减少，且因长期多关节RA而严重影响髋关节以外的其他关节。仅9.1%的患者在骨折前髋关节受累（不包括骨质减少）在X线片上表现明显。与非类风湿性普通人群相比，缺血性坏死率（9.7%）和骨不连率（6.5%）高于预期。继发移位率也很高。在3例缺血性坏死患者中，2例曾接受过皮质类固醇治疗。
