| Objective To investigate the correlation between serum hydroxyl vitamin D level and fragile hip fractures. Methods The clinical data of 181 female fragile hip fracture patients (age ≥50 years), who were admitted to our hospital from January 2013 to December 2015 and undergone serum 25-hydroxyl vitamin D (25OHD) test, were analyzed retrospectively. The age, fracture site, serum 25OHD level and bone mineral density (BMD) of the patients, as well as the outcome of 67 patients followed up for at least one year, were recorded. The correlation between serum 25OHD level and these indices was observed. Results In 181 over 50 years old female patients with fragile hip fractures, there were 127 cases (70.2%) with vitamin D deficiency, 42 cases (23.2%) with vitamin D insufficiency, and 12 cases (6.6%) sufficient vitamin D. The serum 25OHD level in patients who were less than 75 years was markedly higher than that in patients over 75 years old. BMD level in patients with 25OHD over 20ng/mL was higher than in patients with 25OHD less than 20ng/mL. The serum 25OHD level in patients with femoral neck fractures was higher than in patients with inter-trochanter fractures, but the difference was not statistically significant. Among patients followed up within one year, the patients with 25OHD over 20ng/mL had lower fall rate, fracture rate, and all-cause mortality than those with 25OHD less than 20ng/mL, but the difference was not statistically significant. The outdoor action ability in patients with 25OHD over 20ng/mL was markedly higher than that in patients with 25OHD less than 20ng/mL. Conclusion Vitamin D deficiency and insufficiency are prevalent in elderly female patients with fragile hip fractures. Serum 25OHD level is correlated with age, BMD, and the outcome of the patients. |
