Patients with periprosthetic femoral fractures are older adults who are commonly diagnosed with osteoporosis
Authors' conclusion
Low-energy PFF should be considered as an osteoporotic fracture and treated accordingly.
Study context
- Population
- Patients aged ≥ 50 years with low-energy PFF, Lille University Hospital, January 1, 2016 to December 31, 2022
- Participants
- 71 vs 117
- Exposure
- PFF vs native hip fractures
- PFFn = 71
- Native hip fracturen = 117reference
- Outcome
- Adjusted bone mineral density (BMD) T-scores
Methodological detailssingle-centre, observational, linear mixed model adjusted for age, sex and BMI
- Single-centre
- Observational
- Linear mixed model adjusted for age, sex and BMI
