Bottom Line: The ratio of sick beds to total number of beds at the participating hospitals was 19.6% (2,188/11,158) in the urban area and 34.9% (1,963/5,623) in the rural area.There were no apparent differences in place or cause of injury.This difference is estimated to be caused by the high and low incidence of neck fracture in urban and rural areas, respectively.

ABSTRACT

Background: To investigate the differences in the characteristics of femoral neck and trochanteric fractures between urban and rural areas of Kyoto Prefecture in Japan.

Methods: Fracture type (neck vs. trochanteric), age, sex, place where fracture occurred (indoors vs. outdoors), and cause of injury were surveyed among patients aged ≥65 years who sustained hip fractures between 2008 and 2010 and who were treated at 1 of 13 participating hospitals (5 urban, 8 rural). The ratio of sick beds to total number of beds at the participating hospitals was 19.6% (2,188/11,158) in the urban area and 34.9% (1,963/5,623) in the rural area. We also investigated the incidence of hip fracture in Tango medical district as a representative rural area.

Results: There were 1,346 neck (mean age, 82.4 years) and 1,606 trochanteric fractures (mean age, 85.0 years). The ratio of neck to trochanteric fractures was higher in the urban area than in the rural area in all age groups (65-74, 75-84, and ≥ 85 years). There were no apparent differences in place or cause of injury. The incidence of hip fracture in the women of Tango medical district was lower than the national average.

Conclusions: There was a difference in the ratio of neck to trochanteric fractures between urban and rural areas. This difference is estimated to be caused by the high and low incidence of neck fracture in urban and rural areas, respectively.

Figure 1: Comparison of neck-to-trochanteric fracture ratio between urban and rural areas in each age group.

Mentions: In all age groups, the urban area showed a higher ratio of neck fracture than the rural area (Figure 1). Regarding the place of fracture, the percentage of fractures that occurred indoors (excluding not-indicated cases) increased with age: 57.8% (191/331) for subjects aged 65–74 years, 71.3% (785/1,101) for those aged 75–84 years, and 83.2% (1,128/1,356) for those aged ≥85 years (P = 0.0000 for all age groups). In terms of cause of injury, the percentage of simple falls (excluding unknown and not-indicated cases) also increased with age: 74.3% (237/319) for the age group 65–74 years, 85.6% (915/1,069) for the age group 75–84 years, and 88.5% (1,149/1,299) for the age group ≥85 years (P = 0.0385 for ages 75–84 years and ≥85 years, and P = 0.0000 for the other age groups).
