本研究旨在确定1994年日本新泻县股骨近端颈骨折和转子骨折的发病率，并将该发病率与1985年、1987年和1989年新泻报告的发病率进行比较。我们访问了新泻县内所有设有整形外科的医院，并回顾了1994年所有此类骨折患者的病历和X线照片。1994年，新泻县的人口为2483879人（男性1205151人，女性1278728人）。65岁以上人口为428795人（男性172788人，女性256007人），占总人口的17.3%。1994年，共有1 468例颈椎或转子骨折，男性378例，女性1 090例，男女比例为1：2.9。这些骨折的发病率在65岁以上的人是304骨折每10万人口每年。其中颈椎骨折528例，股骨粗隆骨折940例，后者占64%。在新泻，骨折的年龄特异性发病率随年龄呈指数增长，与瑞典和美国报道的相似。然而，这一发生率低于这些国家。将1994年的颈椎和转子骨折数量与1985年、1987年和1989年报告的数量进行比较时，很明显，这些骨折的总数和发病率在这一时期一直在增加。即使调整了这些年中特定年龄人群的差异，骨折也一直在增加。
This study aimed to determine the incidence of cervical and trochanteric fractures of the proximal femur in 1994 in Niigata Prefecture, japan, and to compare this incidence with those previously reported in Niigata in 1985, 1987, and 1989. We visited all hospitals within Niigata Prefecture having an orthopedic department and reviewed the medical records and radiographs of all patients who sustained such fractures in 1994. The population of Niigata Prefecture was determined in 1994 to be 2483 879 (1205151 males and 1278728 females). The population over 65 years of age was 428795 (172788 males and 256007 females), representing 17.3% of the total population. In 1994, there were 1468 cervical or trochanteric fractures in 378 males and 1090 females, with a male-to-female ratio of 1 :2.9. The incidence of these fractures in persons over 65 years of age was 304 fractures per 100000 population per year. Of 528 cervical and 940 trochanteric fractures, the latter accounted for 64% of the total number. The age-specific incidence of the fractures in Niigata exhibited an exponential increase with age, similar to those reported in Sweden and the United States. However, the incidence was lower than in those countries. When comparing the number of cervical and trochanteric fractures in 1994 with the numbers reported in 1985, 1987, and 1989, it is evident that the overall number and incidence of these fractures has been increasing over this period. Even if the difference of the age-specific population among these years is adjusted, the fractures have been increasing.
