BACKGROUND: The purpose of this study was to evaluate the clinical and radiographic outcomes of internal fixation with locking T-plates for osteoporotic fractures of the proximal humerus in patients aged 65 years and older. METHODS: From January 2007 through to December 2015, we recruited 47 patients aged 65 years and older with osteoporotic fractures of the proximal humerus. All fractures had been treated using open reduction and internal fixation with a locking T-plate. We classified the fractures in accordance to the Neer classification system; At the final follow-up, the indicators of clinical outcome-the range of motion of the shoulder (flexion, internal rotation, and external rotation) and the presence of postoperative complications-and the indicators of radiographic outcome-the time-to-union and the neck-shaft angle of the proximal humerus-were evaluated. The Paavolainen method was used to grade the level of radiological outcome in the patients. RESULTS: The mean flexion was 155.0° (range, 90°–180°), the mean internal rotation was T8 (range, T6–L2), and the mean external rotation was 66.8° (range, 30°–80°). Postoperative complications, such as plate impingement, screw loosening, and varus malunion were observed in five patient. We found that all patients achieved bone union, and the mean time-to-union was 13.5 weeks of the treatment. The mean neck-shaft angle was 131.4° at the 6-month follow-up. According to the Paavolainen method, “good” and “fair” radiographic results each accounted for 38 and 9 of the total patients, respectively. CONCLUSIONS: We concluded that locking T-plate fixation leads to satisfactory clinical and radiological outcomes in elderly patients with proximal humeral fractures by providing a larger surface area of contact with the fracture and a more rigid fixation.

OBJECTIVETo investigate the relationship between the risk of osteoporotic fracture in old people and the spinal morphology.
METHODSFrom June 2010 to January 2011, 107 old people's BMD of femoral neck were measured by Dual energy X-ray. A questionnaire survey on fracture risk factors of the 107 aged and data collection were adopted. Among the aged,41 were male and 66 were female,ranging in age from 48 to 82 years old,with an averaged of (67 +/- 6) years old. The fracture risk assessment tools (FRAX) recommended by WHO were adopted. A risk assessment on osteoporotic fracture in old people was done,followed with the calculation of the probability of the hip fracture and the main bone fractures (spine,hip,forearm or shoulder fractures) in ten years. The angles of spine vertebra, spine curvature in the upright positions of the old people were measured by using Spinalmouse. The correlation analysis along with curve fitting analysis between the probability of fracture risk and included angles of spine vertebra, spine curvature were done.
RESULTSThe probability of osteoporotic fracture had a positive relation with thoracic vertebra T7 and T8, thoracic spine curvature,lumbar curvature and incline angle in upright position (P < 0.05).
CONCLUSIONThe old people's morphological characteristics of spine have the ability to reflect the risk level o osteoporotic fracture.

OBJECTIVETo explore the reasons of secondary fracture after percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fractures (OVCFs) and discuss the measure of prevention and cure.
METHODSFrom January 2011 to January 2013, the clinical data of 180 patients with primary OVCFs treated by PVP were retrospectively analyzed. There were 75 males and 105 females, aged from 68 to 95 years old with an average of (79.50 ± 5.45) years. The involved vertebrae were identified according to the clinical symptoms and imaging data. PVP were performed in 362 vertebrae and the patients were followed up with an average of 12 months. Subsequent vertebral fractures were found through the pain's reappearance and MRI or bone scan. The patients were divided into secondary fracture group and no-secondary fracture group according to the subsequent fractures or no. Secondary fracture group was divided into two groups according to gender, and the patients with secondary fracture were also categorized into the original surgical vertebral fractures, adjacent vertebral fracture and remote vertebral fractures. The age, gender, the cement volume, the cement leakage, secondary fracture site, the incidence and type of secondary fracture were observed and compared among different groups.
RESULTSAmong the 362 vertebrae of PVP, there were 109 vertebrae in male and 253 vertebrae in female. And 27 vertebrae (10 in male and 17 in female) of 22 cases (9 males and 13 females) occurred secondary fracture. The second PVP were performed in 13 cases (16 vertebrae) and the third PVP in 2 cases (4 vertebrae); 7 cases (7 vertebrae) were treated with conservative therapy. There was no statistically significant difference on age, gender, cement volume and leakage between secondary fracture group and no-secondary fracture group (P > 0.05). There was no statistically significant difference on the incidence and type of secondary fracture between male and female (P > 0.05). No significant difference was found on the adjacent and remote vertebral fractures (P > 0.05). Most of secondary fracture occurred in 6 months, and whether the single and double side injection, cement leakage had no obvious relation.
CONCLUSIONThere is no significant difference in the subsequent fracture after PVP for the OVCFs different gender and fractured site, and also no significant difference in the adjacent and remote vertebral fractures. The report didn't support the biomechanical viewpoint that vertebral body stiffness increasing after PVP would lead to adjacent vertebral stress increasing and result easily in adjacent vertebral fracture. Secondary fracture occurs always in 6 months after operation, which is the natural course of osteoporosis.

BACKGROUND: There have been equivocal results in studies of the effects of dipeptidyl peptidase-4 inhibitors (DPP-4i) on fractures. In this study, we analyzed the effect of DPP-4i on bone fracture risk in a Korean population. METHODS: We extracted subjects (n = 11,164) aged 50 years or older from the National Health Insurance Service–National Sample Cohort 2.0 from 2009 to 2014. Our control group included subjects without diabetes (n = 5,582), and our treatment groups with diabetes included DPP-4i users (n = 1,410) and DPP-4i non-users (n = 4,172). The primary endpoint was the incidence of a composite outcome consisting of osteoporosis diagnosis, osteoporotic fractures, vertebral fractures, non-vertebral fractures, and femoral fractures. The secondary endpoint was the incidence of each individual component of the composite outcome. Survival analysis was performed with adjustment for age, gender, diabetes complications severity index, Charlson comorbidity index, hypertension medication, and dyslipidemia treatment. RESULTS: The incidence of the composite outcome per 1,000 person-years was 0.089 in DPP-4i users, 0.099 in DPP-4i non-users, and 0.095 in controls. There was no significant difference in fracture risk between DPP-4i users and DPP-4i non-users or controls after the adjustments (P > 0.05). The incidences of osteoporosis diagnosis, osteoporotic fractures, vertebral fractures, non-vertebral fractures, and femoral fractures were not significantly different between DPP-4i users and non-users. The results of subgroup analyses by gender and age were consistent. CONCLUSION: DPP-4i had no significant effect on the risk of fractures in a Korean population.

OBJECTIVE:
To explore the risk factors of hidden blood loss in osteoporosis vertebral compression fractures during percutaneous vertebral augmentation.
METHODS:
From October 2018 to December 2019, 360 patients with osteoporosis vertebral compression fractures who received percutaneous vertebral augmentation were enrolled in this study. The factors analyzed included gender, age, surgical methods, disease course, height, weight, the operative segment, bone mineral density, amount of bone cement, operative time, percentage of height loss, percentage of vertebral height restoration, cement leakage, blood clotting function, preoperative and postoperative hemoglobin and hematocrit and other internal diseases. Total blood loss was calculated by Gross's formula, influential factors of the hidden blood loss were further analyzed by t-test, multivariate linear regression and one-way ANOVA analysis.
RESULTS:
Surgical methods, the operative segment, disease course, cement leakage, preoperative hemoglobin, cement leakage via the basivertebral and segmental vein were significantly correlated with hidden blood loss(P<0.05).
CONCLUSION
Patients with percutaneous kyphoplasty, two-level and multi-level surgery, the course of the disease beyond 6 weeks, cement leakage via the basivertebral and segmental vein, and lower preoperative hemoglobin had more perioperative hidden blood loss.

OBJECTIVETo analyze the perioperative complications of percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fracture.
METHODSFrom June 2009 to December 2011, 63 patients with osteoporotic vertebral compression fracture underwent PKP, there were 18 males and 45 females with an average age of 75.3 years ( ranged, 62 to 91). All patients with severe back pain and without neurological symptoms and signs, which were confirmed by X-ray and MRI. Among them,there were 63 cases with severe osteoporosis, 37 cases with hypertension, 10 with coronary artery disease, 29 with anemia, 26 with diabetes, 11 with chronic obstructive pulmonary diseases and 8 with gastritis and peptic ulcer. The common perioperative complications were retropectively reviewed.
RESULTSPreoperative complications occured in 9 cases (14.3%), including hypostatic pneumonia (1 case), electrolyte disturbances (2 cases), urinary tract infection (2 cases), moderate anemia(2 cases),electrolyte disturbances combined with moderate anemia (1 case), hypostatic pneumonia combined with delirium (1 case). Intraoperative and postoperative. complications occurred in 17 cases (26.9%), there were bone cement correlated complications in 9 cases (14.3%), in which 2 cases of toxic reaction of bone cement and 7 cases of leakage (2 cases had clinical symptoms); there were non-bone cement correlated complications in 3 cases (4.8%), in which 1 case of focal hematoma caused by paracentesis, 1 case of transient nerve injury, 1 case of left intercostal neuralgia;there were transient hyperpathia in 5 cases after operation. All complications result in no severe consequence after treatment.
CONCLUSIONPerioperative complications of percutaneous kyphoplasty are not uncommon,however,these complications may not cause serious consequence after active treatment,so prevention and treatment are important for it.
