PURPOSE: Patients with COPD are well known to be at increased risk for osteoporosis. The chief clinical manifestations of osteoporosis are vertebral and hip fracture. It has been known that 10-30% of COPD patients have clinically important moderate-to-severe grade vertebral fractures found using various radiographic imaging modalities. However, little is known about the relationship between COPD and hip fracture. The aims of this study were to evaluate the frequency of airflow obstruction in patients with femur fracture and to find out the differences according to the presence of airflow obstruction in patients with femur fracture.
METHODS: We enrolled the patients with non-traumatic hip fracture over 1 year period. We evaluated the incidence of airflow obstruction and compared the clinical, spirometric data and bone densitometry according to the presence of airflow obstruction
RESULTS: A total 122 patients were enrolled (M:F=22:100). The mean age of the patients was 78.3±6.91. The prevalence of osteoporosis was 68% (N=83). A total 36.1% (N=44) of patients had airflow obstruction on spirometry. The prevalence of osteoporosis and the bone mineral density were not statistically significant according to the presence of airflow obstruction. However, 85.7% of the patients with GOLD stage 3 or 4 had osteoporosis compared with 67.9% of patients without airflow obstruction.
CONCLUSIONS: In conclusion, 36.1% of patients with hip fracture had airflow obstruction. Osteoporosis was more prevalent in patients with severe airflow obstruction.
CLINICAL IMPLICATIONS: Airflow obstruction is prevalent in patients with hip fracture. Early detection and early management for osteoporosis might be warranted in patients with COPD
