Abstract

Summary

The current study shows that patients aged 50 or more who have sustained an osteoporotic fracture have a significant risk of suffering a new fracture. Refracture risk is also increased when anatomic site of both index and subsequent fracture are the same.

Purpose

The purpose of this study is to describe the profile of a patient sustaining a fragility fracture, the influence of the initial or index fracture on subsequent fracture risk and the role that anatomic site of index and subsequent fracture play on fracture risk.

Methods

In this retrospective observational cohort study, individuals aged ≥ 50 years who sustained at least one clinical fragility fracture were identified from the public health service register between January 1, 2014, and December 31, 2015. Two separate analysis cohorts were identified. Group 1 (index FF) included patients that sustained at least one clinical fragility fracture during the study period. Group 2 (subsequent FF) included those patients from group 1 who sustained at least one clinical subsequent fracture during the following 2 years after index fracture.

Results

A total of 11,986 fractures constituted group 1 (index FF), and 792 constituted group 2 (subsequent FF). The incidence of subsequent fractures was 6.61%, with a major percentage of them (36.99%) identified within the first 6 months following index FF. Hip was the most frequent site for index (30.09%) and subsequent fracture (34.85%). We found an increased risk mainly when anatomic site of index and subsequent FF are the same.

Conclusions

Sustaining a subsequent fracture after an index fracture is a common event in the population over age 50, more commonly occurring within 6 months of index fracture. Analysis of fracture site correlation shows that refracture risk is increased mainly when index and subsequent fracture site are the same.
