Abstract
Introduction and purpose: The aim of this study is to determine the risk profile of a repeat hip fracture based on the patients’ intrinsic characteristics, their associated risk factors and concomitant pathological conditions, with the aim of carrying out preliminary work that might allow subsequent studies to quantify these risk factors.
Materials and methods: Case study and multi-center control: 1576 cases of hip fracture were collected of which 138 (8.76%) were repeat-fractures of the hip (the latter was the test group and the control group comprised the remaining 1574 cases [91.24%]). Variables were analyzed that could represent the risk profile of the patients and their predisposition to an osteoporotic fracture, their modifiable or non-modifiable risk factors and concomitant pathological conditions. Qualitative variables were analyzed using chi square; any necessary adjustments were made by means of Fischer’s exact test when necessary.
Results: The mean age of the control group was 82.45 ± 8.08 (36–102) and 83.26 ± 7.86 (53–100). The difference had no statistical significance (0.7 years). Of all the differences between the single fracture and repeat-fracture groups, the only one with statistical significance was the existence of a maternal history of fracture (p= 0.0034), which is a risk factor for contralateral hip fracture. The other variables studied did not achieve statistical significance independently of the trend seen.
Conclusion: In our series a maternal history of hip fracture is the only predictive factor of a repeat hip fracture.
