Satisfactory 2-year outcome of minimal invasive hybrid stabilization with double treated screws for unstable osteoporotic spinal fractures.

This study evaluates whether the fracture level alters the outcomes of minimally invasive hybrid stabilization (MIHS) with double-threaded, uncemented polyaxial screws for unstable osteoporotic vertebral fractures. This prospective cohort study included 73 patients (71.23% females, mean age: 79.9 ± 8.8 years) with unstable OF 3-4 fractures treated by MIHS between Nov 2015-Jan 2018. Patient characteristics, operative data, clinical outcomes, complications, radiological outcomes, and midterm (24-month) follow-up regarding functionality, pain, and quality of life were analyzed. Patients had thoracolumbar (71.23%), thoracic (10.97%), and lumbar (17.8%) fractures. Operative time was < 120min in 73.97% of patients, with blood loss < 500ml in 97.25% of cases. No in-hospital mortality was recorded. Spine-associated complications occurred in 15.07% of patients, while 36.98% of patients had urinary tract infections (n = 12), pneumonia (n = 5), and electrolyte disturbances (n = 9). The mean length of hospital stay was 13.38 ± 7.20 days. Clinically-relevant screw loosening occurred in 1.7% of screws, and secondary adjacent fractures were diagnosed in 5.48% of patients. The alpha-angle improved significantly postoperatively (mean change: 5.4°) and remained stable for 24 months. The beta-angle improved significantly from 16.3° ± 7.5 to 10.8° ± 5.6 postoperatively but increased slightly to 14.1° ± 6.2 at midterm follow-up. Although no differences were seen regarding baseline data, clinical outcomes, and complications, fracture level significantly altered the COMI score at 24 months with no effect on pain score or quality-of-life. MIHS using polyaxial screws is a safe treatment for single-level osteoporotic spinal fractures. Fracture level did not alter radiological reduction loss; however, it significantly altered patients' function at 24 months.

Osteoporotic vertebral fracture: Our Experience and update

Introduction: Osteoporotic vertebral fracture is a fragility fracture due to osteoporosis and is a growing public health problem. It mainly affects postmenopausal women and men &gt; 50 years. It significantly affects morbidity, financial condition, quality of life and mortality of patients. It presents mainly with back pain, which is mostly manageable with conservative measures. Those with unrelieved pain, severe spinal deformity or neurological impairment would require intervention. The quality of bone and surgical fitness along with associated co-morbidities of these elderly people, require special consideration, indications and appropriate modification of technique and instruments for surgical intervention. Materials and methodology: This prospective study summarizes the management of osteoporotic vertebral fractures from September 2015 to September 2021 in Nepal Medical College, Kathmandu, Nepal. The study included patients with back pain of more than 50 years old age. The backpain was evaluated clinically using visual analogue scale and Oswestry Disability Index, neurological deficits using Frankel grading system and deformity using X-ray. Other investigations included MRI, Dexa scan, Serum calcium and Vitamin D3. Risk factors for developing osteoporosis and OVF were also assessed. Results: Out of the 630 patients of more than 50 years age, presenting in neurosurgical OPD with backache from September 2015 to September 2020, 158 cases were later diagnosed to have osteoporotic spine fractures. There were 122 (77.2%) postmenopausal ladies and 36 (22.8%) gentlemen. All had backpain, with 36% having VAS score of &lt; 3 and 64% had ODI of mild to moderate disability. The neurological deficits were present in 16.4% and mostly were Frankel grade C and D. Significant kyphoscoliosis (Cobb angle more than 20 degrees) in X-ray was present in 18 (11.3%) patients. 88 (55.7%) patients had Dexa scan and T score was less than -2.5 in 88 (56%). Serum calcium was low in (41) 26% and Vitamin D3 was low in (107) 67.7% of the patients. For backpain, all were started on non-operative management. Vertebral augmentation procedure was not available in our institute. Thus, surgery was offered in 44 (28%) of the patients but only 18 (11.4%) agreed for surgery and underwent decompression with long segment fixation. Only 48 patients remained in follow up for more than 2 years and all had satisfactory control of pain with no deterioration in deformity or neurological deficit. There were no significant short or long-term complications or mortality. Conclusion: Osteoporotic vertebral fracture is a very common reason for back pain in people of more than 50 years old affecting their livelihood. The majority responded to conservative treatment. Those indicated for surgery need special consideration in preparation, technique and devices. Preventive measures can help reduce the problem load.

Diagnostic Value of Hounsfield Units for Osteoporotic Thoracolumbar Vertebral Non-Compression Fractures in Elderly Patients with Low-Energy Injuries.

Thoracolumbar vertebral fractures are common pathological fractures caused by osteoporosis in the elderly. These fractures are challenging to detect. This study aimed to evaluate the diagnostic value of Hounsfield units for osteoporotic thoracolumbar vertebral non-compression fractures in elderly patients with low-energy fractures. The retrospective case-control study included elderly patients diagnosed with osteoporotic thoracolumbar vertebral fractures and non-fractured patients who underwent computed tomography examinations for lumbar vertebra issues during July 2017 and June 2020. This study included 216 patients with fractures (38 males and 178 females; average age: 77.28±8.68 years) and 124 patients without fractures (21 males and 103 females; average age: 75.35±9.57 years). The difference in Hounsfield units of the target (intermediate) vertebral body significantly differed between the two groups (54.74 ± 21.84 vs 5.86 ± 5.14; p<0.001). The ratios of Hounsfield units were also significantly different between the two groups (1.38 ± 1.60 vs 0.13 ± 0.23; p<0.001). The cut-off value for the difference in Hounsfield units to detect osteoporotic spine fractures was 25.35, with high sensitivity (98.5%), specificity (99.9%), and the area under the curve (AUC) (0.999, 95% CI: 0.999-1). The cut-off value for the odds ratio of Hounsfield units was 0.260, with high sensitivity (99.1%), specificity (92.7%), and AUC (0.970, 95% CI: 0.949-0.992). The difference between Hounsfield units and the odds ratio of Hounsfield units might help diagnose osteoporotic thoracolumbar vertebral non-compression fractures in elderly patients with low-energy fractures.

Does Early Treatment With Teriparatide Prevent the Need for Surgical Intervention in Osteoporotic Vertebral Compression Fractures.

Retrospective Cohort Study. The primary objective of this study is to evaluate the efficacy of early administration of Teriparatide in preventing the necessity of surgical intervention in individuals with osteoporotic vertebral compression fractures. In a 24-month follow-up retrospective analysis, 191 OVCF patients from January 2016 to October 2020 were randomly assigned to Non teriparatide Group A (n = 104) or Group B teriparatide (n = 87). At baseline, 6months, 1year, and 2years following treatment, demographic data and need of surgical intervention, VAS, ODI, union rates, and kyphosis development, were examined. Our study found that non-teriparatide group individuals had an 11.53% higher risk of non-union formation that required surgery. Only 8.63% of teriparatide group patients needed surgery. Both groups had significant VAS score reductions. Non-teriparatide group scores declined from 8.38 ± 0.74 to 3.15 ± 1.40, while teriparatide group scores decreased from 8.49 ± 0.73 to 1.11 ± 0.31. The 2-year follow-up ODI scores significantly decreased, with values of 25.02 ± 13.94 for non-teriparatide patients and 15.11 ± 2.17 for teriparatide patients. The kyphosis progression angles in the teriparatide group were considerably lower (4.97 ± 0.78°) compared to the other group (8.09 ± 1.25°). With increasing elderly populations, it is necessary to take measures to prevent surgical intervention in osteoporotic spinal compression fractures. Teriparatide can be employed as an early medication in the management of these fractures to avert non-union and the minimise the progression of kyphosis.

Effect of percutaneous vertebroplasty on the treatment of osteoporotic spinal fractures in elderly patients and risk factors for postoperative lower extremity deep vein thrombosis.

To evaluate the effectiveness of PVP (PVP) in treating osteoporotic spinal fractures in the elderly and analyze the risk factors for postoperative deep vein thrombosis (DVT) in the lower extremities. A total of 100 elderly patients with osteoporotic spinal fractures, treated between August 2019 and July 2021, were divided into two groups: PVP (research group, n=50) and conservative treatment (control group, n=50). Outcome measures, including injured vertebrae, pain levels, and treatment outcomes, were retrospectively analyzed. Patients who underwent PVPs were further categorized based on the presence of lower extremity DVT one month post-surgery. Logistic regression analysis was used to identify risk factors for post-surgical lower limb DVT. PVP resulted in a significantly smaller posterior convexity angle of the injured spine and higher anterior, midline, and posterior edges of the injured spine compared to conservative treatment (P<0.001). Patients in the research group had significantly lower visual analogue scale (VAS) scores and higher treatment efficiency compared to those in the conservative treatment group (all P<0.05). Nine cases of lower extremity DVT were observed after PVP. Logistic regression analysis identified age, body mass, smoking, and diabetes as independent risk factors for post-surgical lower extremity DVT. PVP improves spinal function and relieves pain in elderly patients with osteoporotic fractures. However, age, body mass, smoking, and diabetes are independent risk factors for postoperative lower extremity DVT.

Better Outcome after Balloon Kyphoplasty when Compared to Vertebroplasty. Analysis of the Results of a Single Center with a 2 Year Follow up

Introduction: Vertebroplasty means the percutaneous introduction of polymethyl methacrylate into the vertebral bodies that have been weakened by osteoporosis or tumors. Many studies presenting the clinical experience with vertebroplasty and balloon kyphoplasty have been published in recent years. Some authors have reported a higher incidence of new fractures after balloon kyphoplasty and vertebroplasty. The natural course of osteoporosis progression, on the other hand, increases the risk of new fractures, increasing the total number of vertebral fractures.&#x0D; The Indications are:Vertebral compression fractures; Osteoporotic fractures; Metastatic bone tumors and the contraindications are: Infection of the fractured vertebra; Acute hemorrhagic diathesis; Known allergy to cement; Pregnancy&#x0D; Purpose: Our aim was to make a comparative analysis of the results after balloon kyphoplasty and vertebroplasty in patients with osteoporotic fractures of the thoracolumbar spine.&#x0D; Conclusion: Despite the statistically insignificant number of patients included in our series, our results emphasize the superiority of balloon kyphoplasia over vertebroplasia. The lack of complications and the immediate verticalization of our patients immediately after the end of the procedure makes us have more confidence in the balloon kyphoplasia procedure.

Predictive factors for conversion from conservatively to surgically treatment osteoporotic thoracolumbar compression fractures based on sagittal parameters and magnetic resonance imaging features.

To investigate the relationship between sagittal plane characteristics of the spinal column and conservative treatment failure in acute osteoporotic spinal fractures (OSFs). As a retrospective study of single-institute data, thoracolumbar OSF patients with similar propensities in terms of location of fractures and results of bone mineral density were analyzed. Among them, 43 patients (group I) who needed reconstructive surgical interventions and 39 patients (group II) who obtained successful treatment through conservative care were included. General demographic data, radiographic features of fractures, and magnetic resonance imaging (MRI) features of fractures were analyzed. To investigate the relationship between global sagittal alignment of the spine and occurrence of delayed complication following OSFs, radiological sagittal parameters were analyzed. The number of cases requiring reconstructive surgery was significantly higher when the index vertebra showed diffuse or mid-portion bone marrow changes in MRI. In terms of sagittal parameters, pelvic incidence (group I 59.1° ± 11.9°, group II 54.6° ± 9.8°) and thoracolumbar angle (group I 26.5° ± 14.1°, group II 17.4° ± 11.2°) were significantly higher in group I. Logistic regression analysis showed that higher pelvic incidence (OR 1.09, 95% CI 1.01-1.18, p value < 0.05) and higher thoracolumbar angle (OR 1.09, 95% CI 1.02-1.17, p value < 0.05) were significant risk factors for delayed complications requiring reconstructive surgery following OSFs. Delayed complications requiring reconstructive surgery following OSFs are related to sagittal plane parameters of the spine such as high pelvic incidences, in addition to previously known radiographic characteristics of fractures.

Treating Osteoporotic Spinal Fractures in Elderly Patients via a Modified Clinical Bone Cement Injection Technique.

The minimally invasive injection of bone cement (MIIBC) is an effective way to treat senile osteoporotic spinal fractures (OSF) in clinical practice. However, the intraspinal dura and nerves may be damaged when the puncture needle passes through the pedicle. Therefore, in this protocol, the puncture site was optimized during the surgery, selecting the same 1-2 cm away from the surface projection of the diseased vertebra. The needle was punctured along the lateral cortex of the pedicle from the junction of the pedicle and the vertebral body into the vertebral body. Meanwhile, bone cement was used as a filling material, and the MIIBC was performed by a percutaneous puncture at the external edge of the pedicle under C-arm fluoroscopy. This modified puncture site is far away from the spinal canal as possible, thereby reducing the risk of the puncture needles penetrating the spinal canal and damaging the nerves and dura mater. In conclusion, a modified MIIBC by percutaneous lateral pedicle puncture can effectively relieve pain in elderly patients with OSF.

Posterior instrumentation for osteoporotic fractures in the thoracic or lumbar spine: Cement-augmented pedicle screws vs hybrid constructs.

Cement-augmented pedicle screws (CPS) and hybrid construct (HC), consisting of pedicle screws and additional hooks, are common fixation methods for osteoporotic spine fracture. No study has compared surgical results of CPS and HC for treating osteoporotic spine fracture. The aim of the study was to compare surgical results using CPS or HC for osteoporotic fractures of the thoracic or lumbar spine. This retrospective cohort study included 84 patients who received surgical treatment with CPS (n = 43) or HC (n = 41) for osteoporotic spine fractures from January 2011 to December 2015, with a mean follow-up of 67 months. Sixty-five patients with neurological deficits received long posterior instrumentation, short posterior decompression, and posterolateral fusion. The 19 patients without neurologic deficits received long posterior instrumentation without posterior decompression and fusion. Radiographic, clinical, and neurologic outcomes were evaluated. The HC group had significantly shorter operative times (231 vs 258 minutes), greater blood loss (497 vs 427 mL), better immediate postoperative kyphosis reduction (10.6° vs 9.1°), and greater final reduction loss (9.8° vs 7.1°) than the CPS group. In both groups, significant loss of the kyphotic angle was apparent during follow-up. Improved ambulation after surgery occurred in 51.2% and 58.5% of patients in the CPS and HC groups, respectively. Neurologic function after surgery improved 0.5 and 0.7 grades in the CPS and HC groups, respectively. Implants failed in 2.3% and 2.4% of patients in the CPS and HC groups, respectively. The incidence of cement leakage from screw augmentation was 38.9%. The CPS and HC techniques for treating osteoporotic fractures of the thoracic or lumbar spine did not differ statistically in terms of improved radiologic and clinical outcomes, final neurologic and ambulatory function, or implant failure rates, making them equally comparable alternatives.

Risk factors and strategies for recovery quality, postoperative pain, and recurrent fractures between percutaneous kyphoplasty and percutaneous vertebroplasty in elderly patients with thoracolumbar compression fractures: a retrospective comparative cohort study.

With the increase of clinical cases and the improvement of operation, we found that recurrent fracture of the adjacent vertebral body is a common long-term complication of percutaneous kyphoplasty (PKP). However, the mechanism of re-fracture of adjacent vertebrae after PKP has not been unified. Therefore, through retrospective study, this paper discussed the risk factors and countermeasures affecting the quality of rehabilitation, postoperative pain and recurrent fracture in elderly PKP patients. From December 2019 to May 2021, 313 patients with osteoporotic spinal fractures were analyzed retrospectively. Cases were allocated to percutaneous vertebroplasty (PVP; n=130) and PKP (n=183) groups according to the modes of operation. Visual analogue scale (VAS), Cobb angle, and Oswestry disability index (ODI) were evaluated. Based on the occurrence of new fractures, the PKP cohort (n=15) and control cohort (n=32) were classified. Questionnaires analyzed the postoperative re-fractures of people with different characteristics, and the influencing factors of postoperative re-fracture were measured by multivariate logistic regression analysis. The postoperative VAS scores were significantly lower in the PKP group. The ODI scores in the PKP group were considerably lower than those in the PVP group after surgery. Univariate analysis indicated that age, number of injured vertebrae, history of complicated fracture, number of operative vertebrae, and bone mineral density (BMD) were remarkably correlated with recurrent fracture after PKP. Logistic regression analysis indicated that age, operative vertebral body, BMD, and the number of injured vertebrae were independent risk factors for recurrent fracture after PKP. BMI, BMD, low back soft tissue injury, postoperative vertebral height recovery rate, sagittal Cobb angle improvement rate, total diffusion coefficient of bone cement, short-term complications, non-union, and recurrent fracture were the main risk factors of residual low back pain after PKP. The clinical efficacy of PKP in elderly patients with thoracolumbar vertebral compression fracture is superior to that of PVP. Clinical attention should be paid to identifying high-risk factors for complications after PKP, and preventive measures should be implemented to help reduce the occurrence of recurrent fractures and postoperative residual pain.

Clinical Effect Observation of Percutaneous Vertebroplasty in the Treatment of Osteoporotic Spinal Fractures in the Elderly

Clinical Effect Observation of Percutaneous Vertebroplasty in the Treatment of Osteoporotic Spinal Fractures in the Elderly

Comparison of different approaches of percutaneous vertebroplasty in the treatment of osteoporotic spinal compression fractures and analysis of influencing factors of re-fracture.

To compare the functional and radiological outcome of different approaches of percutaneous vertebroplasty (PVP) in the treatment of osteoporotic vertebral compression fractures (OVCF), and to analyze the factors affecting postoperative re-fracture in patients with OVCF. Medical data of 76 patients with OVCF who underwent PVP in our hospital from January 2021 to December 2021 were analyzed retrospectively. Based on the different intraoperative approaches, patients were divided into Unilateral-group (n=36) and Bilateral-group (n=40). The perioperative indexes, clinical efficacy, and spinal nerve function of the two groups were compared. Logistic regression analysis was used to determine the risk factors of postoperative re-fracture in patients with OVCF. The functional outcome was assessed with Oswestry disability index (ODI), American Spinal Injury Association (ASIA) nerve function classification and pain with Visual analogue scale (VAS). The radiological outcome was assessed by noting change of anterior vertebral height and change of kyphosis Cobb angle. The amount of intraoperative bleeding, the number of X-ray irradiation and the volume of injected bone cement in the Unilateral-group were lower, and the operation time was shorter than Bilateral-group (all P<0.05). One week after the operation, the anterior height of the vertebral body was higher, the Cobb angle of kyphosis was lower, the VAS score was higher, and the ASIA grade was lower in the Unilateral-group compared to the Bilateral-group (P<0.05). Logistic regression analysis showed that the age, bone mineral density, volume of bone cement injection and PD were risk factors of postoperative re-fracture in patients with OVCF. Unilateral PVP treatment of OVCF has the advantages of less intraoperative bleeding, less X-ray irradiation and shorter operation time. At the same time, bilateral PVP is associated with improved bone cement dispersion, and the effect of improving patients' pain is better than that in the Unilateral PVP. Postoperative risk of re-fracture in OVCF patients correlated with age, bone mineral density, amount of bone cement injection and pedicle diameter.

Vertebral augmentation in osteoporotic spine fractures: WFNS Spine Committee recommendations.

The aim of this study was to formulate the WFNS Spine Committee guidelines on indications, outcomes, and complications of vertebral augmentation in osteoporotic spine fractures. Computerized literature was searched from 2010 to 2021 using keywords "vertebral augmentation," "osteoporotic fracture," "technique," "surgery," "complication," and "outcome." PubMed yielded 92 articles whereas Google scholar resulted in 120 articles. 29 articles were studied in detail. The studies comprised of seventeen RCT's, two prospective non-randomized studies, three retrospective studies, and seven systematic reviews. The statements were produced to reach a consensus in two separate meetings of WFNS Spine Committee. The statements were voted and reached a positive or negative consensus using Delphi method. Drafted statements on "Vertebral Augmentation in osteoporotic Spine Fractures" were voted upon by expert panelists in Virtual WFNS Spine Committee Consensus Meetings conducted on January 11, 2021, and February 13, 2021. Statements reaching positive consensus provided the basis for the WFNS guidelines regarding vertebral augmentation in osteoporotic spine fractures. WFNS Spine Committee recommendations on vertebral augmentation in osteoporotic spine fractures are summarized in this article. Vertebral augmentation is superior to conservative treatment for vertebral osteoporotic fractures but has conflicting results on comparison with placebo. Both vertebroplasty and kyphoplasty are equally effective. Most of the studies regarding the efficacy of vertebral augmentation procedures to reduce pain have been largely inconclusive. It is suggested that further high quality, better designed randomized controlled studies are required to establish the role of vertebral augmentation in spine osteoporotic compression fractures.

An observational study of vertebroplasty and kyphoplasty for osteoporotic spinal fractures: utilisation and outcomes in England using an administrative dataset.

To investigate use, safety and functional outcomes of vertebroplasty (VP) and balloon kyphoplasty (BKP) techniques for osteoporotic spinal fracture for patients operated on within the National Health Service in England. This was an observational analysis of administrative data. Data were extracted from the Hospital Episodes Statistics database for the period 1st April 2011 to 31st March 2018 for all VP and BKP procedures. Patients aged < 19years, with metastatic carcinoma and undergoing other decompression procedures, were excluded. The primary outcome was repeat spinal surgery within 1year. Secondary outcomes were 30-day emergency readmission, death within 1year, extended hospital stay, post-procedural pain within 30days and post-procedural haemorrhage or infection within 30days. Multilevel, multivariable logistic regression was used to adjust for covariates. Data were available for 5792 VP and 3136 BKP patients operated on at 96 hospital trusts. In the 63 trusts that conducted more than 20 procedures during the study period, the proportion of procedures conducted as BKP varied from 0 to 100%. There was no difference in any of the outcomes between VP and BKP patients or between trusts performing ≥ 70% and ≤ 30% of procedures as BKP. With regard to the outcomes studied, there is no evidence that VP is associated with poorer outcomes than BKP.

A Comparison between Accurate Unilateral Puncture Paths Planned by Preoperative and Conventional Unilateral Puncture Techniques in Percutaneous Vertebroplasty.

Objective Comparison of the clinical and radiological effects of precise unilateral puncture pathway prepared by preoperative CT data and traditional unilateral puncture pathway in PVP administration for the treatment of osteoporotic vertebral compression fractures. Summary of background data. PVP is a commonly used vertebral augmentation operation for the treatment of painful spinal compression fractures. A percutaneous unilateral approach is routinely used to get access to the vertebral body. PVP has had positive clinical results in a number of prior investigations. Numerous difficulties and issues, including puncture difficulty, radiation exposure, cement leakage, spinal cord or nerve damage, and intraspinal hematoma, have been described in contrast. Methods This prospective study included 300 patients with single-level lumbar osteoporotic vertebral compression fractures, 180 females and 120 males, with an average age of 71.5 years. PVP was performed on randomized subjects using two distinct puncture procedures. The patients were separated into two groups: Preoperative planning, in which a precise unilateral puncture path was established using preoperative CT data, and Conventional planning, in which multiple puncture procedures were used. The participants were followed up on after surgery and mostly assessed on clinical and radiological results. The visual analogue scale for pain and the 36-item Short Form Health Survey (SF-36) questionnaire for health status were used to assess clinical outcomes. Radiation dosage, bone cement distribution, vertebral body height, and kyphotic angle were used to evaluate radiological results. Results Participants remained monitored for 12 to 28 months on average. 151 individuals were treated with accurate unilateral puncture paths planned by preoperative CT data percutaneous vertebroplasty and 149 patients were treated with conventional unilateral paths percutaneous vertebroplasty. The Preoperative planning group's operation time and radiation dose were significantly lower than the Conventional group's; nevertheless, the volume of injected cement was significantly higher in the Preoperative steering committee than in the Conventional group. All patients in both groups had much less pain after the operations when compared to their preoperative suffering. There were no statistically significant variations between groups when the visual analogue scale and the 36-Item Short Form Health Survey were compared. Neither group showed a substantial decrease in the kyphotic angle during the follow-ups. In the Preoperative planning group, the kyphotic angle improved much more than in the Conventional group. At 1 month postoperatively, 16 patients in the Conventional group experienced apparent discomfort in the puncture sites because to facet joint violation. At the latest follow-up, all of the patients' discomfort had vanished after receiving local block therapy. Conclusion Both preoperatively designed precise unilateral puncture pathways and traditional unilateral puncture procedures PVP are reasonably safe and effective for individuals with painful osteoporotic spinal compression fractures. Unilateral puncture courses planned via preoperative PVP, on the other hand, absorbed less radiation and operation time, as well as a good level of deformity correction and amount of injected cement, and caused less complications than traditional unilateral PVP.

Location and Effect of Bone Cement in Percutaneous Vertebroplasty for Osteoporotic Vertebral Compression Fractures.

In this study, the effectiveness and use of bone cement are thoroughly elaborated, and the role of bone cement on percutaneous vertebroplasty (PVP) fixed joints and its distribution on PVP are also elucidated. The aim of this study was to investigate the effect of unilateral and bilateral bone cement distribution on the clinical efficacy of PVP in the treatment of osteoporotic vertebral compression fractures (OVCF) of the thoracolumbar spine. A total of 60 patients with thoracolumbar OVCF (T11-L2) hospitalized in our hospital from January 2020 to January 2021 were studied. All patients had thoracolumbar OVCF. Under the guidance of the C-arm machine, unilateral PVP was performed. According to the distribution of bone cement across the midline, the patients were divided into two groups: the unilateral group (37 cases): bone cement was distributed on one side of the midline of the vertebral body, and the bilateral group (23 cases): bone cement was distributed on both sides of the midline. Visual analogue scale (VAS), vertebral height recovery values, and preoperative and postoperative Cobb's angle were recorded at 3 days, 1 month, 3 months, and 6 months. The differences between the two groups were compared and analyzed to evaluate the clinical efficacy. There was a statistically significant difference in VAS scores between the two groups before and after surgery (P < 0.05), but there was no statistically significant difference in VAS scores between the two groups at 3 days, 1 month, 3 months, and 6 months after surgery (P > 0.05). There were statistically significant differences in vertebral height recovery value and Cobb's angle between the two groups before and after surgery (P < 0.05).

Osteoporotic Vertebral Fractures: An Analysis of Readability and Quality of Web-Based information

IntroductionVertebral compression fractures are among the most common fragility fractures with significant morbidity and mortality. With an aging population, the incidence of these fractures is on the rise. In this age of social and electronic media, there is a plethora of online information available. While access to healthcare information has increased, most of these websites remain beyond the comprehension of their target audience.ObjectiveTo assess the readability and quality of online information regarding osteoporotic vertebral fractures.MethodsA search for the terms osteoporotic vertebral fractures, osteoporotic spinal fractures, and fragility spinal fractures was performed using the top five search engines. Eighty-three websites were identified and analyzed. Quality assessment was done using the DISCERN and Journal of the American Medical Association (JAMA) tools while readability was analyzed using the Flesch Reading Ease Score (FRES), Flesch Kincaid Grade (FKG), and Gunning Fog Index (GFI).ResultsThe mean DISCERN score was 39.55 while the mean JAMA was 2.2. Readability testing revealed a mean FRES score of 49.26 with 16 websites having a score of > 60, FKG 8.38, and GFI of 9.51. 33 websites had an FKG score of 8 or below 8.ConclusionThe above results indicate that web-based information relating to osteoporotic vertebral fractures is of variable quality and readability. Although 40 % of websites are at the eighth grade or below level, only 16 % of websites are above the FRES score of 60, which makes online information difficult to comprehend by an average patient.

Double-Balloon Kyphoplasty Results in Better Radiographic Outcomes Than a Single-Balloon Kyphoplasty in Treating Osteo-Porotic Spinal Fractures

Background: Studies have found that unilateral and bilateral kyphoplasty have comparable clinical outcomes. Only a few studies have compared the radiographic results of using unilateral vs. simultaneous bilateral approaches. We aimed to examine and compare the radiographic results of unilateral (UKP) vs. bilateral simultaneous double-balloon kyphoplasty (DKP) for treating symptomatic vertebral compression fractures (VCF). Methods: A retrospective cohort of all patients treated for VCF by DKP and UKP over five years in a single medical center. From 2009 to 2012, we routinely performed UKP; from 2012, DKP was the routine due to potential benefits in vertebral realignment. We evaluated pre- and post-surgical fracture characteristics including vertebral height, sagittal and coronal Cobb angle, and fracture reduction. Statistical analysis included a t-test for independent variables and Pearson’s correlation. Results: The study cohort consisted of 81 patients (75.8 years ± 10.86) who underwent surgery, with a total of 119 vertebras. We performed 89 UKP on fractured vertebras and 30 DKP on 30 vertebrae. The UKP average fluoroscopy radiation exposure was 15.8 mGy (±11.5) per level compared to 11.2 mGy (±8.7) for DKP, p = 0.03. DKP showed significant fracture reduction, 2.8 degrees of Cobb angle, equaling the patient positioning effect on fracture reduction. Conclusion: DKP results in better fracture reduction than UKP, and equals the effect of patient positioning without increased radiation exposure or adverse events.
