AIM
To determine if there was a seasonal variation in adults undergoing total hip arthroplasty for end stage hip disease due to osteoarthritis (OA) or sequelae of developmental dysplasia of the hip (DDH).
METHODS
The total hip registry from the author's institution for the years 1969 to 2013 was reviewed. The month of birth, age, gender, and ethnicity was recorded. Differences between number of births observed and expected in the winter months (October through February) and non-winter mo (March through September) were analyzed with the χ test. Detailed temporal variation was mathematically assessed using cosinor analysis.
RESULTS
There were 7792 OA patients and 60 DDH patients who underwent total hip arthroplasty. There were more births than expected in the winter months for both the DDH ( < 0.0001) and OA ( = 0.0052) groups. Cosinor analyses demonstrated a peak date of birth on 1 October.
CONCLUSION
These data demonstrate an increased prevalence of DDH and OA in those patients born in winter.
目的
确定因骨关节炎（OA）或髋关节发育不良（DDH）后遗症而接受终末期髋关节疾病全髋关节置换术的成年人是否存在季节性差异。
方法
回顾了作者所在机构1969年至2013年的全髋关节置换登记资料。记录出生月份、年龄、性别和种族。采用χ检验分析冬季月份（10月至2月）和非冬季月份（3月至9月）观察到的出生人数与预期出生人数之间的差异。使用余弦分析对详细的时间变化进行数学评估。
结果
有7792例OA患者和60例DDH患者接受了全髋关节置换术。DDH组（<0.0001）和OA组（=0.0052）在冬季月份的出生人数均多于预期。余弦分析显示出生高峰日期为10月1日。
结论
这些数据表明冬季出生的患者中DDH和OA的患病率增加。
