Abstract

Background

We have studied stress fractures of the bowed femoral shaft (SBFs) among elderly Japanese for over a decade. On the other hand, severely suppressed bone turnover (SSBT) after long-term bisphosphonates (BPs) use has been considered to be one of the causes of low-energy diaphyseal femoral fractures, often called atypical femoral fractures (AFFs). Some studies have shown that BPs use for more than 5 years is associated with an increased risk of AFFs. Here, we present a report of our SBF case series experienced in the past 15 years in order to examine whether bowing deformity should be considered among the causes of AFFs.

Methods

Subjects were 13 Japanese female patients with low-energy femoral shaft fractures. Mean age at injury was 77.0 years (range 67–88 years). All patients met the criteria of the AFFs’ case definition. The first author treated 11 of the 13 patients over 8 years (2005–2012) based on the concept of SBFs. Regarding the regional characteristics of these patients, 10 were treated at 2 rural hospitals, and 3 were treated at 3 urban hospitals. Retrospectively, we assessed fracture type and location, existence of fracture on the contralateral side, bowing deformity, and duration of BPs use.

Results

All 13 cases were AO/OTA type 32-A. Incomplete or previous fracture on the contralateral side was noted in 10 cases. Obvious bowing deformity of the femoral shaft was noted in 12 cases. BPs were taken in 7 cases, only 3 of which involved BPs use for more than 5 years.

Conclusions

We experienced 12 cases of low-energy femoral shaft fractures associated with bowing deformity. Six cases were not treated with BPs at all. Stress fractures associated with a femoral shaft bowing deformity do actually exist and should be recognized as another cause of AFFs.

Acknowledgments

This study is a retrospective clinical case series of 13 patients. We obtained consent from 5 patients, complying with the principles laid down in the Declaration of Helsinki. Since this study is retrospective research reaching back more than 10 years, we could not obtain consent from the other 8 patients due to interrupted follow-up. However, our reporting of patients is completely anonymous, protecting the privacy and dignity of these patients.
