Hip bone density is associated with concomitant distal ulna fracture in the setting of distal radius fracture
Authors' conclusion
In patients with surgically treated distal radius fracture, lower hip bone density was consistently associated with distal ulna involvement, particularly the metaphyseal subtype, characterizing conditional fracture-pattern variation within this selected surgical population.
Study context
- Population
- Adults aged ≥ 45 years with surgically treated low-energy distal radius fracture (2020–2024)
- Participants
- 236 adults
- Exposure
- USF + UMF vs DRF; UMF vs USF
- DRFn = 85reference
- USFn = 129
- UMFn = 22
- Outcome
- Distal ulna involvement (USF + UMF vs DRF) and ulnar metaphyseal vs ulnar styloid fracture (UMF vs USF)
Methodological detailsunivariable and multivariable logistic regression in two stages
- Univariable and multivariable logistic regression in two stages
Main finding
As reported in the abstract
Association of low hip-YAM (≤ 70%) with distal ulna involvement
- Low hip-YAM (≤ 70%) showed the most consistent association with ulna involvement across both analytic stages, with a stronger association in the second stage differentiating UMF from USF
- Other variables, including radius fracture severity, exhibited minimal or no association
Observational data: associations, not effects.
Further findings
Distal ulna involvement (proportion of all patients)
- Distal ulna involvement
- 64.0%
