- Purpose
The incidence of hip fractures is increasing due to an increase in elderly populations because elderly patients often have accompanying diseases, such as cognitive impairment or dementia, which may lead to missed fractures. Therefore, this study assessed the utility of bone scans in detecting missed fractures in elderly patients.
Materials and Methods
This study analyzed the data from 178 patients treated from January 2014 to March 2023. The inclusion criteria were patients who had hip fractures with osteoporosis over 70 years old. Bone scans were performed on average 10 days after injury. The rate and trend of missed fractures not detected in the initial diagnosis were determined based on sex, age, dementia status, and the presence of osteoporosis.
Results
Among the 178 hip fracture patients over 70 years old, 37 patients had a history of being diagnosed with dementia, and 141 patients had never been diagnosed. Missed fractures were confirmed in 49 cases (42 patients) (23.6%). The dementia group had 13 missed fractures, and the non-dementia group had 36 missed fractures, but there was no significant difference. Rib fractures were most common, followed by vertebral fractures.
Conclusion
Missed diagnoses of fractures were common among elderly hip fracture patients. A whole body bone scan appeared to be effective in detecting missed fractures. Therefore, identifying accompanying fractures through bone scans and delivering appropriate treatment can play an important role in postoperative rehabilitation.
