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.

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.

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.

OBJECTIVETo investigate the correlative factors of non-surgical vertebral fractures after percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fractures(OVCFs).

METHODSFrom August 2009 to September 2011, 126 patients who underwent single-level PVP for OVCFs were included in this study. They were followed up with an average time of 13.6 months,divided into the refracture group and non-refracture group according to the onset of non-surgical vertebral fractures or not. In refracture group,there were 14 males and 18 females with an average age of (67.63+/-7.28) years(ranged, 54 to 82); and in non-refracture group,there were 40 males and 54 females with an average age of (66.26+/-6.79) years (ranged, 55 to 76). The refracture group wps divided again into adjacent vertebral fracture (AVF) group (7 males and 13 females) and remote vertebral fracture(RVF) group (4 males and 8 females). The age, sex, bone mineral density(BMD), injecting bone cement volume, the recovery rate of vertebral body height,kyphosis corrected degree were recorded and the correlative factors of non-surgical vertebral fractures were analyzed.

RESULTSThere was no statistically significant differences in age, sex, BMD, injecting bone cement volume and kyphosis corrected degree between refracture group and non-refracture group (P>0.05), and there was statistically significant difference in the recovery rate of vertebral body height (P<0.05). There was no statistically significant difference in BMD, kyphosis corrected degree between adjacent vertebral fracture group and non-refracture group (P>0.05); and there was statistically significant difference in injecting bone cement volume,recovery rate of vertebral body height(P<0.05). There was no statistically significant difference in BMD,injecting bone cement volume,recovery rate of vertebral body height, kyphosis corrected degree between remote vertebral fracture group and non-refracture group (P>0.05).

CONCLUSIONRecovery of vertebral body height may prefigure increasing risk of refracture in non-surgical vertebral body for the patient with OVCFs after PVP, and the adjacent vertebral fracture maybe concerned with injecting bone cement volume and recovery rate of vertebral body height.

OBJECTIVE: To observe the clinical efficacy of targeted sealing with high viscosity bone cement and secondary injection of low viscosity bone cement in the treatment of OVCFs patients with the fracture lines involved vertebral body margin. METHODS: The elderly patients who underwent vertebroplasty for osteoporotic vertebral compression fractures from January 2019 to September 2021 were selected as the screening objects. Through relevant standards and further CT examination, 56 patients with fracture lines involving the anterior wall or upper and lower endplates of the vertebral body were selected for the study. There were 21 males and 35 females, aged from 67 to 89 years old with an average of (76.58±9.68) years. All 56 patients underwent secondary injection of bone cement during operation. Only a small amount of high viscosity cement was targeted to seal the edge of the vertebral body for the first time, and low viscosity cement was injected to the vertebral bodies during second bolus with well-distributed. The operation time, bone cement volume and bone cement leakage were recorded, and the pain relief was evaluated by visual analogue scale (VAS). RESULTS: All patients were followed up for more than 3 months and the surgeries were successfully complete. The operation time was (50.41±10.30) min and the bone cement volume was (3.64±1.29) ml. The preoperative VAS was (7.21±2.41) points, which decreased significantly to (2.81±0.97) points 3 days after operation(P<0.05). Among the 56 patients, 2 cases(3.57%) had bone cement leakage, 1 case leaked to the paravertebral vein, and 1 case slightly bulged to the paravertebral through the crack when plugging the vertebral crack. Both patients had no obvious clinical symptoms. CONCLUSION In vertebroplasty surgery, targeted sealing of high viscosity bone cement and secondary injection of low viscosity bone cement can reduce intraoperative bone cement leakage and improve the safety of operation.
