A limited body of data is available with regard to the incidence of osteoporotic fractures in Germany. Most of the data published thus far have been derived from hospital records or health insurance settlements. The aim of the present study was to prospectively register four types of fractures in an urban population. The data we obtained were compared with the results of retrospective analysis procedures in order to determine the differences and underlying errors.
An urban population of 200 413 residents was investigated prospectively with regard to osteoporosis-associated fractures over a period of 12 months. All fractures were recorded and confirmed on radiographs. The results of this analysis were compared with the data from the Statistical Bureau and the International Classification of Disease (ICD) registers of the hospitals.
A total of 979 fractures occurred during the period of investigation. The most common type was the distal radius fracture (395; 197.1 per 100 000). The retrospective detected data of the Statistical Bureau were 31, 56% lower than the actual number of fractures. A retrospective analysis of fractures based on the ICD registers of the hospitals revealed an over-registration rate of 26.67%.
Retrospective methods of fracture registration do not provide sufficiently reliable data.
德国骨质疏松性骨折的发病率数据有限。迄今为止，大多数已发表的数据都来自医院记录或医疗保险结算。本研究的目的是前瞻性地登记城市人群中的四种骨折类型。我们获得的数据与回顾性分析程序的结果进行了比较，以确定差异和潜在错误。
在 12 个月的时间内，对 200413 名城市居民进行了前瞻性骨质疏松性骨折调查。所有骨折均通过影像学记录并确认。该分析的结果与统计局和医院的国际疾病分类（ICD）登记处的数据进行了比较。
在调查期间共发生 979 例骨折。最常见的类型是桡骨远端骨折（395 例；每 100000 人中有 197.1 例）。统计局的回顾性检测数据比实际骨折数量低 56%。基于医院 ICD 登记处的骨折回顾性分析显示，过度登记率为 26.67%。
骨折登记的回顾性方法不能提供足够可靠的数据。
