Background: Fragility fracture significantly increases risk of future fracture. The fragility fracture cycle should be disrupted. The secondary fracture prevention is important for the patients with fragility hip fracture. The pharmacotherapy for osteoporosis is important for prevention of new fracture. However, many patients with hip fracture do not receive osteoporosis treatment. This retrospective study investigates the influence of bone mineral density (BMD) assessment on the initiation of anti-osteoporosis medications in the hospitalized patients with fragility hip fracture., Methods: This retrospective research enrolled 1211 patients with fragility hip fracture 50 years of age and older. Among 1211 patients aged from 50 to 103 years with the average age of 77.83 ± 9.95 years, there were 807 females and 404 males. There were 634 fractures of femoral neck and 577 intertrochanteric fractures of femur. We examined whether patients had received bone mineral density assessment and received anti-osteoporosis therapy during the period of hospitalization. The patients were divided into BMD assessment group and no BMD assessment group. Measurement data were expressed as mean ± standard deviation and compared with t test. All parameters of groups were compared with Chi-square test., Results: Of 1211 patients, 331 (27.33%) had received BMD assessment and 925 (76.38%) had received anti-osteoporosis drugs during the period of hospitalization. The rate of bisphosphonate use was lower and only 11.31% in the total patients. The anti-osteoporosis treatment rate was 93.66% in the patients receiving BMD assessment and 69.89% in the patients without BMD assessment (p < 0.01). The zoledronate use significantly increased from 6.7% in the patients without BMD assessment to 23.56% in the patients receiving BMD assessment (p < 0.01)., Conclusions: BMD assessment is a good basis for communication between patients and orthopedic surgeons. BMD assessment significantly increases the initiation of osteoporosis treatment and bisphosphonate use in the patients with hip fracture during the period of hospitalization.

To investigate whether there is an influence on the results of lumbar spine bone mineral density (BMD) measured by dual-energy X-ray absorptiometry (DXA) under three different hip flexion angles (90°, 45°, 0° of hip flexion). We collected a total of 60 outpatients, including 44 females (56.4 ± 5.7 years) and 16 males (50.2 ± 13.7 years). The DXA results of the lumbar spine were scanned and analyzed in three different positions with hip flexion of 90°, 45°, and 0°. We found that there was no significant difference in the area of interest, bone mineral content, BMD, and vertebral body height of the lumbar vertebral body measured by DXA in three hip flexion positions of 90°, 45°, and 0°; Pearson’s correlation analysis showed that lumbar BMD in hip flexion 90° was correlated with it in hip flexion 45° (r = 0.998, P＜0.01) and in hip flexion 0° (r = 0.996, P＜0.01) respectively. There was no statistically significant difference in the diagnosis of BMD between 90° and 45° hip flexion (P = 0.903), which was the same as 90° and 0° hip flexion (P = 0.822). Therefore, we conclude that different hip flexion angles can be used in lumbar BMD detection by DXA, which is beneficial to patients who have difficulty in hip flexion, especially for elderly patients with osteoporosis.

Objectives: To compare the effects of percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP) in treating Kümmell's disease (KD) patients. Methods: This prospective cohort study involved 19 KD patients (20 involved vertebrae). The surgical selection was dependent on clinical stages and postural correction status. The status of vertebral reduction, amount of cement injection, and amount of cement leakage during the surgery were recorded. The anterior vertebral height and kyphotic angle were measured by X-ray scan. The degree of low back pain and the quality of life were assessed by the visual analog scale and Oswestry disability index, respectively. Results: On the third-day post-operation and the last follow-up, anterior vertebral height was increased, kyphosis angle was reduced, low back pain was relieved, and life quality was improved in both groups compared with pre-operation. There was no significant difference between the two groups in cement amount, cement leakage rate, vertebral height correction, and kyphotic correction angle. The nerve function of stage III patients with spinal cord injury was improved from a Frankel grade D to E. Expert Opinion: PVP and PKP could be used in treating KD patients, and the surgical selection could be dependent on the clinical stages and status of postural correction. Conclusion: PVP and PKP could be used in treating KD patients, and the surgical selection could be dependent on the clinical stages and status of postural correction. [ABSTRACT FROM AUTHOR]

Background: This study assessed the differences in femoral geometry and bone mineral density between femoral neck fragility fractures and trochanteric fractures.Methods: One hundred and seventeen patients were divided into femoral neck and trochanteric fracture groups. There were 69 patients with femoral neck fractures, 20 men and 49 women with an average age of 75.1 ± 9.6 years and an average body mass index (BMI) value of 21.6 ± 4.1 kg/m2. The trochanteric group consisted of 48 patients, 16 men and 32 women with an average age of 78.1 ± 9.1 years and an average BMI value of 21.5 ± 4.3 kg/m2. All patients underwent dual-energy X-ray absorptiometry (DXA) of the contralateral hip; hip structural analysis (HSA) software was used to analyze the femoral geometry parameters, including hip axis length (HAL), neck-shaft angle (NSA), cross-sectional area (CSA), the cross-sectional moment of inertia (CSMI), the buckling ratio (BR), and cortical thickness.Results: The cortical thickness in the intertrochanteric region was reduced in the trochanteric fractures group compared to the femoral neck fracture group (P < 0.05). There were no statistically significant differences (P > 0.05) in gender, age, height, weight, or BMI between the two groups. In addition, no statistically significant differences (P > 0.05) were found in the CSA, CSMI, or BR of the femoral neck or the intertrochanteric region between the two groups. There were no statistically significant differences (P > 0.05) in femoral neck cortical thickness between the two groups.Conclusions: Cortical thickness thinning in the intertrochanteric region may be one of the relevant factors causing different types of hip fractures, especially in elderly patients.

Background: Vertebral fracture is the most common fragility fracture but it remains frequently unrecognized and is underdiagnosed worldwide. In this retrospective study, we examined the prevalence of moderate and severe vertebral fractures on chest radiographs of hospitalized female patients aged 50 years and older and determined missed diagnosis of vertebral fractures in the original radiology reports.Methods: 3216 female patients 50 years of age and older were enrolled in our study. The patients' medical records including their original radiology reports and lateral chest radiographs were retrospectively reviewed by the study radiologists who had training certificates from the International Society for Clinical Densitometry (ISCD). Vertebral fractures between thoracic spine T4 and lumbar spine L1 were identified and classified using Genant's semi-quantitative scale. The definition of vertebral fractures used in this study was Genant grade 2 or higher.Results: The study radiologists identified 295(9.2%) patients with grade 2 or 3 fractured vertebrae, total 444 vertebrae on 3216 chest radiographs. The prevalence of vertebral fracture was 2.4% in women aged 50-59 yrs., 8.9% in women aged 60-69 yrs., and 21.9% in women aged≥70 yrs. There were 213 patients with a single vertebral fracture, 49 patients with two vertebral fractures and 33 patients with ≥ three vertebral fractures. Fractured vertebrae were identified with greater frequency in thoracic spine T11,12 and lumbar spine L1. According to our statistics, 66.8% of patients with vertebral fractures found in this study were undiagnosed in the original radiology reports.Conclusions: Vertebral fracture is common on chest radiographs but it is often ignored by radiologists. Genant's semiquantitative assessment is a simple and effective method for detecting vertebral fracture. Because osteoporotic vertebral fracture increases the risk of new fractures, radiologists have an important role in accurately diagnosing vertebral fractures. [ABSTRACT FROM AUTHOR]
