Erosions at the antero-superior angles of C4 and C5 developed in 11 patients (22%) with rheumatoid arthritis of less than one year's duration were followed-up over a 10-year period. These erosions do not appear to have been described before.
在病程不到一年的11例（22%）类风湿关节炎患者中，C4和C5椎体前上角出现了侵蚀，并进行了为期10年的随访。此前似乎未曾描述过这些侵蚀情况。
