Comparative Study
Comparison Between Intraoperative Target Area Cement-Enhanced Percutaneous Vertebroplasty and Conventional Percutaneous Vertebroplasty for Osteoporotic Thoracolumbar Non-Total Vertebral Fractures.
AIM
To compare the efficacy and feasibility of target area cement-enhanced percutaneous vertebroplasty (PVP) and conventional PVP in osteoporotic thoracolumbar non-total vertebral fractures.
MATERIAL AND METHODS
Retrospective analysis of one hundred and two patients treated in our hospital from March 2020 to May 2021 and divided into groups A (targeted) and B (conventional PVP). The Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), anterior vertebral height ratio, intraoperative bleeding, operative time, bone cement volume, complications, and refracture of the injured vertebra were evaluated in both groups.
RESULTS
The 2 days and 1-year post-operative VAS and ODI scores improved significantly in both groups (p < 0.05). The 2 days post-operative VAS and ODI scores were better in group A (p < 0.05), and there was no significant difference in the scores between the groups at the last follow-up (p > 0.05). The anterior vertebral height ratios were significantly higher in both groups 2 days postoperatively (p < 0.05); however, there was no significant difference in the 2 days and 1-year post-operative ratios in group A (p > 0.05). The anterior vertebral height ratio reduced in group B after 1 year compared to the 2 days post-operative value (p < 0.05). There was no statistical difference in intraoperative bleeding and the operative time between the groups (p > 0.05), and the bone cement volume was lesser in group A (p < 0.05). Six patients in group A and four patients in group B demonstrated cement leakage, the difference was not statistically significant (p > 0.05). Three patients in group A and 11 patients in group B demonstrated refracture, the difference was statistically significant (p < 0.05).
CONCLUSION
Target area cement-enhanced PVP can effectively relieve short-term pain and functional disability and reduce the long-term possibility of secondary collapse. Therefore, it is a technically feasible and efficacious method for the treatment of osteoporotic thoracolumbar non-total vertebral fractures.

INTRODUCTION
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.
EVIDENCE ACQUISITION
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.
EVIDENCE SYNTHESIS
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.
CONCLUSIONS
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.

Comparative Study
The aim of this study was to compare and evaluate clinical results before and after vertebroplasty in the treatment of myeloma-induced vertebral fractures. Success of the surgery was defined by increased or reduced pain intensity before and after the treatment, as assessed using the visual analog scale (VAS). The study was designed as a retrospective-prospective study. The study included 26 patients, 14 women and 12 men. Data on patients treated for myeloma-induced vertebral fractures were collected at the Department of Orthopedics, Osijek University Hospital Centre. The following data were analyzed: gender, duration of illness, intensity of pain before and after treatment (using VAS), radiological changes before and after treatment, grade of vertebral fracture, and extracorporeal cement leakage from the vertebral body to the surrounding tissue during the procedure. Difference in pain intensity before and after the surgery was statistically significant. All patients complained of pain before the surgery (pain intensity median 8), whereas after the surgery, pain intensity decreased in all patients (pain intensity median 2). In conclusion, improvement in clinical results of the treatment of myeloma-induced vertebral fractures with vertebroplasty proved to be significant.

Three-Dimensional Reconstruction of a CT Image under Deep Learning Algorithm to Evaluate the Application of Percutaneous Kyphoplasty in Osteoporotic Thoracolumbar Compression Fractures.
In order to investigate the therapeutic evaluation of percutaneous kyphoplasty (PKP) for the treatment of osteoporotic thoracolumbar compression fractures by three-dimensional (3D) reconstruction of computed tomography (CT) based on the deep learning V-Net network, the traditional V-Net was optimized first and a new and improved V-Net was proposed. The introduced U-Net, V-Net, and convolutional neural network (CNN) were compared in this study. Then, 106 patients with osteoporotic thoracolumbar compression fractures were enrolled, and 128 centrums were divided into the test group with 53 cases of PKP and the control group with 53 cases of percutaneous vertebroplasty (PVP) according to different surgical protocols. All patients underwent CT scan based on the improved V-Net, and data of centrum measurement indicators, pain score, and therapeutic evaluation results of the modified Macnab were collected. The Dice coefficient of the improved V-Net was observably higher than that of U-Net, V-Net, and CNN, while the Hausdorff distance was lower than that of U-Net, V-Net, and CNN ( < 0.05). The anterior height, central height, and posterior height of the centrum were significantly higher than those in the control group after operation (3, 5, and 7 days), while the Cobb angle of vertebral kyphosis was significantly lower than that in the control group ( < 0.05). The score of visual analog scale (VAS) and analgesic use score of patients in the test group were markedly lower than those in the control group (3, 5, and 7 days after operation), < 0.05. Besides, the excellent and good rate of the test group was remarkably higher than that of the control group, < 0.05. Hence, the improved V-Net had better quality of segmentation and reconstruction than the traditional deep learning network. Compared with PVP, PKP was helpful in restoring the height of the centrum in patients with osteoporotic thoracolumbar compression fractures and correct kyphosis, with better analgesic effect safety.

BACKGROUND
In clinical practice, we have found that the pain caused by thoracolumbar osteoporotic vertebral compression fracture (OVCF) is sometimes not limited to the level of the fractured vertebrae but instead occurs in areas far away from the injured vertebrae, such as the lower back, area surrounding the iliac crest, or buttocks, and this type of pain is known as distant lumbosacral pain. The pathogenesis of pain in distant regions caused by thoracolumbar OVCF remains unclear.
OBJECTIVES
To compare the clinical efficacy and imaging outcomes of percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) in the treatment of distant lumbosacral pain accompanied by thoracolumbar OVCF and to explore the possible pathogenesis of distant lumbosacral pain caused by thoracolumbar OVCF.
STUDY DESIGN
Retrospective study.
SETTING
A university hospital spinal surgery departments.
METHODS
A total of 62 patients who underwent vertebral augmentation for thoracolumbar OVCF with lumbosacral pain were included and divided into the PVP group (28 cases) and the PKP group (34 cases). The Visual Analog Scale (VAS) was used to evaluate the severity of local and distant lumbosacral pain, and the Chinese modified Oswestry Disability Index (CMODI) was used for functional assessment. The anterior vertebral height (AVH) of the fractured vertebrae and local kyphotic angle were measured on plain radiographs. The average follow-up time was 28.62 ± 8.43 months in the PVP group and 29.22 ± 9.09 months in the PKP group.
RESULTS
Within the 2 groups, the VAS score of local pain, VAS score of distant lumbosacral pain, and CMODI score at 3 days postoperatively and at the last follow-up improved significantly compared with the scores before surgery. However, there was no significant difference between the 2 groups. At 3 days postoperatively and at last follow-up, the AVH and Cobb angle in the 2 groups improved significantly compared with those before surgery, but the magnitudes of AVH improvement and Cobb angle correction were significantly larger in the PKP group than in the PVP group.
LIMITATIONS
First, this study is retrospective and may be prone to selection bias. Second, because of cultural and linguistic differences, the original version of the Oswestry Disability Index could not be properly understood and completed by people in mainland China. Therefore in this study, the CMODI was used, but the correlation coefficients of the CMODI within and between groups were 0.953 and 0.912, respectively. Third, a pain diagram was not used to accurately reflect the location of pain in the distant lumbosacral region.
CONCLUSIONS
Both PVP and PKP can effectively alleviate pain in the distant lumbosacral region caused by thoracolumbar OVCF, and distant lumbosacral pain associated with thoracolumbar OVCF may be considered vertebrogenic referred pain.

PURPOSE
As the trend toward minimally invasive and percutaneous interventions continues, the importance of appropriate surgical data visualization becomes more evident. Ineffective interventional data display techniques that yield poor ergonomics that hinder hand-eye coordination, and therefore promote frustration which can compromise on-task performance up to adverse outcome. A very common example of ineffective visualization is monitors attached to the base of mobile C-arm X-ray systems.
METHODS
We present a spatially and imaging geometry-aware paradigm for visualization of fluoroscopic images using Interactive Flying Frustums (IFFs) in a mixed reality environment. We exploit the fact that the C-arm imaging geometry can be modeled as a pinhole camera giving rise to an 11-degree-of-freedom view frustum on which the X-ray image can be translated while remaining valid. Visualizing IFFs to the surgeon in an augmented reality environment intuitively unites the virtual 2D X-ray image plane and the real 3D patient anatomy. To achieve this visualization, the surgeon and C-arm are tracked relative to the same coordinate frame using image-based localization and mapping, with the augmented reality environment being delivered to the surgeon via a state-of-the-art optical see-through head-mounted display.
RESULTS
The root-mean-squared error of C-arm source tracking after hand-eye calibration was determined as [Formula: see text] and [Formula: see text] in rotation and translation, respectively. Finally, we demonstrated the application of spatially aware data visualization for internal fixation of pelvic fractures and percutaneous vertebroplasty.
CONCLUSION
Our spatially aware approach to transmission image visualization effectively unites patient anatomy with X-ray images by enabling spatial image manipulation that abides image formation. Our proof-of-principle findings indicate potential applications for surgical tasks that mostly rely on orientational information such as placing the acetabular component in total hip arthroplasty, making us confident that the proposed augmented reality concept can pave the way for improving surgical performance and visuo-motor coordination in fluoroscopy-guided surgery.

OBJECTIVE
The objective of this study was to explore the impact of sarcopenia and sagittal parameters on the residual back pain (RBP) after percutaneous vertebroplasty (PVP) for treatment of osteoporotic vertebral compression fracture (OVCF).
METHODS
This retrospective study included elderly patients (age range 60-90 years) with OVCF treated with PVP from January 2015 and December 2020 in our hospital. The skeletal muscle mass index (SMI) was calculated by dividing the T12 pedicle level muscle cross-sectional area by the square of body height from chest CT to diagnose sarcopenia. The radiological parameters for measuring the sagittal alignment were included: C7-sagittal vertical axis (SVA), T1 pelvic angle (TPA), lumbar lordosis (LL), thoracic kyphosis (TK), pelvic tilt (PT), sacral slope (SS), pelvic incidence (PI).
RESULT
According to whether the VAS score > 4, patients were divided into RBP group (56 patients) and Control group (100 patients). There was no difference in age, gender, body mass index, BMD, surgical segment, bone cement usage between the groups (P > 0.05). The SMI in RBP group (27.3 ± 5.1) was significantly lower compared to that in Control group (36.8 ± 3.2) (P < 0.05). Sarcopenia was present in 19 patients (20.3%) in RBP group, which was significantly more than that in Control group (P < 0.05). C7-SVA and TPA was significantly larger in the RBP group than in the Control group (P < 0.05). PI and LL was significantly smaller in the RBP group compared to the Control group (P < 0.05). However, no significant differences between the two groups with respect to TK, SS and PT (P > 0.05).
CONCLUSION
Poor sagittal parameters and sarcopenia in OVCF patients after PVP were more prone to residual back pain. Larger C7-SVA, TPA and PI-LL mismatch could increase the incidence of RBP in elderly patients with single-segment osteoporotic compression fractures.

METHODS
Clinical and radiological data of 204 patients were reviewed. The patients were divided into Group A (PVP alone) and Group B (PVP and FB combined therapy) according to treatments. Back pain was evaluated with Visual Analog Scale (VAS) and Oswestry Disability Index (ODI). The operation, fluoroscopic exposure time, and bone cement leakage were recorded. The test, Student's -test, and repeated measures analysis of variance were used to compare the differences between the two groups.
RESULTS
There were 125 patients in Group A and 79 patients in Group B. Their baseline characteristics were similar ( > 0.05). The mean VAS scores of Group A and Group B were 7.03 and 7.21 at admission, 4.7 and 3.2 at 1 day after operation, 4.0 and 3.0 at 3 months, and 2.2 and 2.2 at 12 months after operation, respectively. The mean ODI scores of Group A and Group B were 30.9 and 29.8 at admission, 17.6 and 17.7 at 3 months, and 10.5 and 10.9 at 12 months after operation, respectively. The mean operation time and fluoroscopic exposure time of Group A (35.6 minutes and 7.2 seconds, respectively) was significantly shorter than that of Group B (45.7 minutes and 11.7 seconds, respectively, < 0.01). The incidence of bone cement leakage and new fractures after operation did not have statistically significant difference between groups.
CONCLUSION
PVP and FB combined therapy could provide better pain relief than PVP alone in short term after operation in patients with OVCFs associated back pains.

To evaluate the clinical safety and efficacies of percutaneous vertebroplasty (PVP), percutaneous kyphoplasty (PKP), and percutaneous mesh-container-plasty (PMCP) for the treatment of vertebral compression fractures (VCFs), a retrospective study of 90 patients with VCFs who had been treated by PVP (n = 30), PKP (n = 30), and PMCP (n = 30) was conducted. The clinical efficacies of these three treatments were evaluated by comparing their PMMA cement leakages, cement patterns, height restoration percentages, wedge angles, visual analogue scales (VAS), and oswestry disability index (ODI) at the pre- and post-operative time points. 6.67%, 3.33%, and 0% of patients had PMMA leakage in PVP, PKP, and PMCP groups, respectively. Three (solid, trabecular, and mixed patterns), two (solid and mixed patterns), and one (mixed patterns) types of cement patterns were observed in PVP, PKP, and PMCP groups, respectively. PKP and PMCP treatments had better height restoration ability than PVP treatment. PVP, PKP, and PMCP treatments had significant and similar ability in pain relief and functional recovery ability for the treatment of VCFs. These results indicate minimally invasive techniques were effective methods for the treatment of VCFs. Moreover, these initial outcomes suggest PMCP treatment may be better than both PVP treatment and PKP treatment.

Biportal endoscopic posterior lumbar decompression and vertebroplasty for extremely elderly patients affected by lower lumbar delayed vertebral collapse with lumbosacral radiculopathy.
BACKGROUND
Lower lumbar osteoporotic vertebral compression fracture in extremely elderly patients can often lead to lumbosacral radiculopathy (LSR) due to delayed vertebral collapse (DVC). Surgical intervention requires posterior instrumented lumbar fusion as well as vertebral augmentation or anterior column reconstruction depending on the cleft formation and intravertebral instability. However, it is necessary to decide on surgery in consideration of the patient's frail status, surgical invasiveness, and rehabilitation. In the lower lumbar DVC without intravertebral instability, biportal endoscopic posterior lumbar decompression and vertebroplasty (BEPLD + VP) can be simultaneously attempted. This study aimed to assess the clinical outcomes of BEPLD + VP for the treatment of DVC-related LSR.
METHODS
This retrospective case series enrolled 18 consecutive extremely elderly (aged ≥ 75-year-old) patients (6 men and 12 women) who had lower lumbar (at or below L3) DVC-related LSR. Patients who require anterior column reconstruction, such as cleft formation accompanied by intravertebral instability and patients who have not been followed for more than 6 months, were excluded from this study. All patients underwent BEPLD + VP under epidural anesthesia. Clinical results were evaluated by the visual analog scale (VAS) score and the modified Japanese Orthopedic Association (mJOA) scores.
RESULTS
Most of the patients had DVC affecting level L4, with the deformation being a flat type or concave type rather than a wedge type. The VAS score (back and leg) significantly decreased from 7.78 ± 1.17 and 6.89 ± 1.13 preoperatively to 2.94 ± 0.64 and 2.67 ± 1.08 within 2 postoperative days (p < 0.001). The mJOA score significantly improved from 4.72 ± 1.27 preoperatively to 8.17 ± 1.15 in the final follow-up (p < 0.001). The mean recovery rate (RR) in the last follow-up was 56.07% ± 9.98. Incidental durotomy was reported in two patients and epidural hematomas in another two patients; however, all patients improved with conservative treatment, and no re-operation was required.
CONCLUSIONS
BELPD + VP was a type of salvage therapy that reduces surgical morbidity, requires major spine surgery under general anesthesia and provides good clinical outcomes in extremely elderly patients with DVC-related LSR.
