Prevalence of Osteoporosis in Patients with Distal Radius Fracture from Low-Energy Trauma

Introduction: Osteoporosis is a devastating problem leading to significant morbidity and mortality. Patients with osteoporosis usually present with fractures from low-energy trauma and falls, commonly of the distal radius, which may precede more severe fractures like fracture of the neck of femur, but data from Thailand are limited. The objective of our study was to determine the prevalence of osteoporosis in patients with distal radius fracture from low-energy trauma. Materials and Methods: This was a descriptive retrospective study, performed at Thammasat University Hospital in Thailand, from January 2011 to June 2017. Patients aged more than 50 years with distal radial fractures from low-energy trauma with available bone mineral density (BMD) result were included. Patients with known secondary causes of osteoporosis were excluded. Patients were grouped by age, sex, and BMD status (normal, osteopenic and osteoporotic). Results: One hundred out of 351 patients with distal radial fractures had bone mineral density data but only 79 (73 females) met the inclusion criteria. Most patients were aged 60-69 years old (n=31, 42.5%). 47 (59.5%) patients were osteoporotic, 23 (29.1%) osteopenic, and 9 (11.4%) were normal. Seven (6 osteoporotic) patients suffered a more severe fracture subsequently. No deaths were recorded. Conclusion: Our study found a high rate of osteoporosis mostly in females, consistent with published literature. Assessing BMD is crucial in middle age and elderly patients with fractures to better manage osteoporosis and prevent more severe fractures in the future.
