ABSTRACT

Percutaneous vertebroplasty (PVP) is a surgical procedure that involves injecting polymethylmethacrylate (PMMA) bone cement into the diseased vertebrae to rapidly relieve pain and strengthen the vertebrae. We reported a 73-year-old patient who underwent percutaneous vertebroplasty (PVP) surgery for thoracolumbar vertebral compression fracture. After the surgery, the patient experienced symptoms such as chest tightness and dyspnea. Further examination revealed multiple high-density foreign bodies in the blood vessels/heart and concomitant multi-organ dysfunction. It was considered that the multi-organ embolism was caused by bone cement leakage. The patient improved after undergoing surgical treatment and anticoagulant therapy.

ABSTRACT

Background: Low-dose following up computed tomography (CT) of percutaneous vertebroplasty (PVP) that involves the use of bone cement usually suffers from lightweight metal artifacts, where conventional techniques for CT metal artifact reduction are often not sufficiently effective. This study aimed to validate an artificial intelligence (AI)-based metal artifact correction (MAC) algorithm for use in low-dose following up CT for PVP. Methods: In experimental validation, an ovine vertebra phantom was designed to simulate the clinical scenario of PVP. With routine-dose images acquired prior to the cement introduction as the reference, low-dose CT scans were taken on the cemented phantom and processed with conventional MAC and AI-MAC. The resulting image quality was compared in CT attenuation, image noise, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR), followed by a quantitative evaluation of the artifact correction accuracy based on adaptive segmentation of the paraspinal muscle. In clinical validation, ten cases of low-dose following up CT after PVP were enrolled to test the performance of diagnosing sarcopenia with measured CT attenuation per cemented vertebral segment, via receiver operating characteristic (ROC) analysis. Results: With respect to the reference image, no significant difference was found for AI-MAC in CT attenuation, image noise, SNRs, and CNR (all P>0.05). The paraspinal muscle segmented on the AI-MAC image was 18.6% and 8.3% more complete to uncorrected and MAC images. Higher area under the curve (AUC) of the ROC analysis was found for AI-MAC (AUC =0.92) compared to the uncorrected (AUC =0.61) and MAC images (AUC =0.70). Conclusions: In low-dose following up CT for PVP, the AI-MAC has been fully validated for its superior ability compared to conventional MAC in suppressing artifacts and may be a reliable alternative for diagnosing sarcopenia.

ABSTRACT

OBJECTIVE: To investigate the occurrence and risk factors for low back pain post-percutaneous vertebroplasty (PVP) in osteoporotic vertebral compression fractures (OVCF) patients. METHODS: A retrospective analysis was conducted of 148 OVCF patients treated from March 2020 to 2023. The incidence of low back pain post-PVP was recorded, and logistic regression analysis was used to identify associated risk factors. RESULTS: Low back pain occurred in 34 out of 148 patients (22.97%). Logistic regression identified age (>75) (P=0.039), number of fractured vertebrae (≥2) (P=0.004), presence of lumbar spine comorbidity (P=0.019), emotional status (P=0.006), site of fracture (P=0.006), and preoperative fascial injury (P=0.039) as independent risk factors influencing the development of low back pain after PVP in OVCF patients. Receiver operating characteristic (ROC) curve analysis showed that age (>75), number of fractured vertebrae (≥2), lumbar spine comorbidities, and site of fracture had area under the curve (AUC) values of 0.626, 0.614, 0.623, and 0.667, respectively, in predicting low back pain post-PVP. CONCLUSION: Age, number of fractured vertebrae, presence of lumbar spine comorbidities, emotional status, site of fracture, and preoperative fascial injury are significant independent risk factors for the occurrence of low back pain after PVP in patients with OVCF. These findings are crucial for alleviating postoperative low back pain and provide valuable insight for postoperative pain management.

ABSTRACT

Purpose: To evaluate the efficacy and safety of combined microwave ablation (MWA) and vertebral augmentation (VA) in the treatment of spinal metastases with posterior wall defects. Patients and Methods: A retrospective review was conducted for 67 patients (42 men, 25 women) with painful spine metastases and posterior wall defects who underwent MWA combined with VA. Among these patients, 52 vertebrae had no epidural invasion and 33 had mild invasion but did not compress the spinal cord. Procedural effectiveness was determined by comparing visual analog scale (VAS) scores and Oswestry disability index (ODI) scores before the procedure and during the follow-up period. Results: The procedure was technically successful in all patients. The mean VAS score declined significantly from 6.85 ± 1.81 before the procedure to 3.27 ± 1.97 at 24 h, 1.96 ± 1.56 at 1 week, 1.84 ± 1.50 at 4 weeks, 1.73 ± 1.45 at 12 weeks, and 1.71 ± 1.52 at 24 weeks post-procedure (p < 0.01). The mean ODI score was lower post-procedure than before the procedure (p < 0.001). Transient nerve injury occurred in two patients (SIR classification D), and the incidence of asymptomatic bone cement (SIR classification A) was 43.5% (37/85). Conclusion: MWA combined with VA is an effective and safe treatment for painful spine metastases with posterior wall defects.

ABSTRACT

OBJECTIVE: To investigate the clinical significance of using 3D printing guides in modified unilateral puncture percutaneous vertebroplasty (PVP) for the treatment of osteoporotic vertebral compression fractures (OVCF), and to explore a new method for preventing paravertebral vein leakage during PVP in conjunction with a previous study of the optimal puncture-side bone cement/vertebral volume ratio(PSBCV/VV%). METHODS: This retrospective study analyzed 99 patients who underwent unilateral puncture PVP between January 2023 and December 2023. Patients were divided into a guide plate group (46 patients) and a conventional group (53 patients). The guide plate group underwent modified unilateral puncture PVP with the guidance of 3D printing guides, while the conventional group underwent unilateral puncture PVP using the conventional pedicle approach. The distribution of bone cement, surgical outcomes, and the occurrence of cement leakage into paravertebral veins were observed in both groups. RESULTS: The guide plate group had significantly shorter operating time and required fewer fluoroscopies compared to the conventional group. The amount of bone cement volume (BCV) used in the guide plate group was higher, but the amount of bone cement volume on the puncture side(PSBCV), the PSBCV/VV%, and the rate of paravertebral vein leakage were lower in the guide plate group compared to the conventional group (P < 0.05). Within each group, significant improvements in anterior vertebral margin height, Cobb angle, visual analog scale (VAS) score, and Oswestry Disability Index (ODI) were observed at 1 day and 1 month postoperatively compared to preoperative values (P < 0.05). CONCLUSION: Using 3D printing guides in modified unilateral puncture PVP is a safe and effective method for treating OVCF. And it has the advantages of short operation time, less fluoroscopy, even distribution of bone cement, and a low rate of paravertebral vein leakage.

ABSTRACT

OBJECTIVE: This study analyzes the safety and efficacy of percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) treatments for Stage III Kummell's disease without neurological symptoms, comparing the advantages and disadvantages of these two minimally invasive surgical methods. METHODS: A retrospective analysis was conducted on 53 patients with non-neurological Stage III Kummell's disease treated with PVP and PKP at our hospital from December 2018 to January 2023. Patients were divided into PVP (25 cases) and PKP (28 cases) groups based on the surgical method. There were no significant differences in general preoperative data between the two groups (all p > 0.05), ensuring comparability. The study compared surgical duration, volume of bone cement injected, distribution pattern of bone cement, rate of bone cement leakage, and preoperative, postoperative, and final follow-up scores of Visual analogue scale(VAS) and Oswestry disability index(ODI). Additionally, relative anterior height of the injured vertebrae, and Cobb angle of deformity, along with their changes at preoperative, postoperative, and final follow-up stages were calculated and analyzed. RESULTS: No significant preoperative differences were observed between the groups (p > 0.05). The PKP group had longer surgeries, higher cement volumes (p < 0.001), and lower leakage rates (p < 0.05), with primarily chunky cement distributions versus mixed distributions in the PVP group. No complications other than cement leakage occurred. VAS and ODI scores showed no significant changes at various time points (p > 0.05) but improved significantly from preoperative (p < 0.001). Both groups saw improved vertebral heights and Cobb angles post-surgery (p < 0.05), with more significant improvements in the PKP group (p < 0.05). Over time, both groups experienced gradual vertebral height loss and increased Cobb angles, more pronounced in the PKP group (p < 0.05). At the final follow-up, there were no statistical differences in vertebral height and Cobb angle between the two groups (p > 0.05). CONCLUSION: The study evaluates the safety and efficacy of PVP and PKP for Stage III Kummell's disease without neurological symptoms, comparing the merits of both minimally invasive techniques.

ABSTRACT

Osteoporosis, and the consequences derived from it, such as fragility fractures, constitute a growing public health problem. Suffering from a fracture of this nature is the main risk factor for suffering a new fracture. It is documented that vertebral compression fractures lead to significant morbidity and mortality, in the short and long term, as well as other complications, such as sagittal imbalance and hyperkyphosis of the segment. However, we have not found documentation that analyzes the medium and long-term consequences of these injuries, assessing the type of treatment used, and the economic impact they represent. The purpose of this review is to analyse the main recent literature on the subject and make a breakdown of the consequences of these fractures in various spheres, such as economic, quality of life, sagittal balance and radiographic parameters, pain or mortality; as well as a brief analysis of epidemiology and natural history. CONCLUSION: Osteoporotic fractures constitute an emerging problem, both in the medical and economic fields. The consequences and sequelae on the patient are multiple and although surgical options offer good long-term results, it is necessary to properly select the patient, through multidisciplinary teams, to try to minimise potential complications.

ABSTRACT

Poly(methyl methacrylate) (PMMA) bone cements have been widely used in orthopedics; thanks to their excellent mechanical properties, biocompatibility, and chemical stability. Barium sulfate and zirconia are usually added into PMMA bone cement to enhance the X-ray radiopacity, while the mechanical strength, radiopacity, and biocompatibility are not well improved. In this study, an insoluble and corrosion-resistant ceramic, tantalum carbide (TaC), was added into the PMMA bone cement as radiopacifies, significantly improving the mechanical, radiopaque, biocompatibility, and osteogenic performance of bone cement. The TaC-PMMA bone cement with varied TaC contents exhibits compressive strength over 100 MPa, higher than that of the commercial 30% BaSO4-PMMA bone cement. Intriguingly, when the TaC content reaches 20%, the radiopacity is equivalent to the commercial bone cement with 30% of BaSO4 in PMMA. The cytotoxicity and osteogenic performance indicate that the incorporation of TaC not only enhances the osteogenic properties of PMMA but also does not reduce cell viability. This study suggests that TaC could be a superior and multifunctional radio-pacifier for PMMA bone cement, offering a promising avenue for improving patient outcomes in orthopedic applications.

ABSTRACT

OBJECTIVE: To evaluate the safety and effectiveness of the lateral or posterolateral percutaneous vertebroplasty (PVP) of osteolytic C1-C2 lesions performed under computed tomography (CT) guidance and local anesthesia. MATERIALS AND METHODS: Retrospective study of 16 consecutive patients (11 females and 5 males, aged from 24 to 86 years, median 65.5 years) who underwent 17 lateral or posterolateral PVP. Pain status was assessed using a visual analog scale (VAS). Patients were evaluated preoperatively as baseline and at 24 hours, 1, 6, 12 months postoperatively, or until the patient died or was lost to follow-up. The Oswestry Disability Index (ODI) was used to evaluate the patients' functional disability preoperatively. The adverse events were recorded using the SIR classification. RESULTS: The technical success was 100% (17/17) for a median SINS score about 13.5 (IQR [6.75, 20.25]). Mean clinical follow up was 10.1 months (range, 6-36 months; median 19.5 months, IQR [4, 35]). Mean VAS score decreased significantly from 7.5 ± 2.1 preoperatively to 1.6 ± 1.5 24 hours postoperatively, and 1.0 ± 1.1, 1.5 ± 1, and 0.5 ± 1.5 at 1, 6, 12 months respectively (all p<.001). No severe adverse events were observed but 3 cases of asymptomatic cement leakage (SIR grade 1) (17.6% (3/17)). CONCLUSIONS: Lateral and posterolateral PVP performed under CT guidance and local anesthesia is safe and effective to treat symptomatic osteolytic C1-C2 lesions.

ABSTRACT

Adjacent vertebral fracture (AVF) is a serious complication of percutaneous vertebroplasty (PVP) or kyphoplasty (PKP) for osteoporotic vertebral compression fracture (OVCF). This study aimed to explore the incidence and risk factors of AVF following PVP or PKP in postmenopausal women. The incidence of AVF was determined by spinal radiographic examinations. The potential risk factors of AVF were identified by univariate analysis, followed by multivariate logistic regression analyses to determine the independent risk factors. In total, 674 postmenopausal women who were treated with PVP or PKP from December 2019 to February 2022 were enrolled in the study. Among them, 58 (8.61%) women experienced an AVF following PVP or PKP. After adjusting for confounding factors, BMI (OR [95% CI] 0.863 [0.781-0.952]; p = 0.003), previous history of OVCF (OR [95% CI] 1.931 [1.044-3.571]; p = 0.036), and Hounsfield unit (HU) value (OR [95% CI] 0.979 [0.967-0.990]; p < 0.001) were found to be independent risk factors of AVF following PVP or PKP in postmenopausal women. The ROC analysis revealed that the BMI and HU thresholds were 21.43 and 65.15, respectively. In conclusion, the incidence of AVF was 8.61%. BMI, previous history of OVCF and HU value were independent risk factors of AVF following PVP or PKP in postmenopausal women.

ABSTRACT

BACKGROUND: The quality of life of elderly patients after vertebroplasty is influenced by various factors. Although the EuroQol 5-Dimension 3-Level (EQ-5D-3L) scale has been widely used to assess quality of life, the factors affecting the long-term postoperative quality of life of elderly vertebroplasty patients in China have not been thoroughly studied. METHODS: This retrospective study included 519 patients aged 65 years and older who underwent elective vertebroplasty. We collected baseline data from these patients and conducted telephone follow-ups 12 months postoperation to evaluate their EQ-5D-3L health utility scores and EuroQol Visual Analogue Scale (EQ-VAS) scores. Univariate and multivariate linear regression models were used to analyse the factors affecting quality of life. RESULTS: Of the 519 patients, the majority were female (78.0%), aged 65 to 95 years, with an average age of 75.2 years. Twelve months postoperation, pain/discomfort was the most commonly reported issue for 68.4% of patients. The median EQ-5D-3L health utility score was 0.783, with a range between 0.450 and 0.887; the median EQ-VAS score was 75, ranging from 60 to 85. Multivariate linear regression analysis indicated that older age, hormone use, higher American Society of Anesthesiologists (ASA) grades, nondrinking habits, and low albumin levels were found to be independent risk factors affecting long-term quality of life in elderly patients after vertebroplasty. Additionally, a history of tumours, the number of vertebral compression fractures, and bone mineral density were also crucial influencing factors. CONCLUSIONS: Based on the use of the EQ-5D-3L Chinese utility scoring system, we evaluated the quality of life of patients aged 65 and above 12 months after vertebroplasty. This study identified several factors related to postoperative quality of life in elderly vertebroplasty patients, providing crucial evidence for further clinical decisions and patient education.

ABSTRACT

OBJECTIVE: To evaluate the effectiveness, pain level, and lung function in elderly patients with osteoporotic thoracic vertebral compression fractures using bone filling mesh bag technology compared to curved vertebroplasty. METHODS: This retrospective analysis reviewed 72 elderly patients with osteoporotic thoracic vertebral compression fractures treated at Xindu District People's Hospital of Chengdu between February 2021 and January 2022. The patients were separated into two groups according to surgery approach: an observation group using bone filling mesh bag technology and a control group using curved vertebroplasty. The overall response rate, pain degree, pulmonary function, life quality grades, surgical indicators, and bone cement leakage rates of the two groups were evaluated. RESULTS: The variation in overall response rate (P=0.420), pain degree (P=0.270), pulmonary function (peak expiratory flow: P=0.660, forced expiratory volume in the first second: P=0.775, forced vital capacity: 0.062), and life quality grades (physical health: P=0.949, social function: P=0.935, physiological function: P=0.970, vitality: P=0.778) between the observation group and the control group after treatment was not statistically meaningful. The Cobb angle (P<0.001) and vertebral height (P<0.001) of patients in the observation group were significantly higher than those in the control group after therapy. The leakage rates of bone cement (intervertebral disc leakage, paravertebral vein leakage, paravertebral soft tissue leakage) of patients in the observation group were notably lower than those in the control group after therapy (P=0.029). CONCLUSION: Bone filling mesh bag technology offers significant improvements in Cobb angle and vertebral height for treating elderly patients with osteoporotic thoracic vertebral compression fractures, and reduced the leakage rate of bone cement. This technique achieves comparable therapeutic outcomes to curved vertebroplasty.

ABSTRACT

The main event of osteoporosis is fragility fractures. Vertebral compression fractures are the most commonly fragility fracture related to osteoporosis. Our goal is to review the available literature to confirm or deny concepts learned about spinal cementation and adapt our clinical practice according to scientific evidence. In the complex world of spine surgery, constant innovations seek to improve the quality of life of patients. Among these, vertebral augmentation has emerged as an increasingly popular technique, but often shrouded in myths and misunderstandings. In this systematic review, we will thoroughly explore the truths behind vertebral augmentation, unravelling common myths and providing a clear insight into this technique. As specialists in the field, it is crucial to understand the reality surrounding these interventions to offer our patients the best possible information and make informed decisions.

ABSTRACT

To investigate the relationship between preoperative blood glucose levels and long-term all-cause mortality in patients with osteoporotic vertebral compression fractures (OVCF) who underwent percutaneous vertebroplasty (VP). This single-center retrospective study involved a chart review of patients admitted for VP to treat OVCF between 2013 and 2020. Patients with pathological or multiple fractures or those who did not undergo bone mineral density assessment were excluded. All relevant information was collected from electronic medical records. The survival status of all patients was confirmed at the end of March 2021. Cox proportional hazard models with multivariate adjustments were used to examine the effects of blood glucose levels on all-cause mortality. Overall, 131 patients were retrospectively analyzed (mean age: 75.8 ± 9.3 years, male patients: 26.7%) with a median follow-up period of 2.1 years. Preoperative hyperglycemia (hazard ratio: 2.668, 95% confidence interval [CI] 1.064, 6.689; p = 0.036) and glucose levels (hazard ratio: 1.007, 95% CI 1.002-1.012; p = 0.006) were found to be independently associated with a higher risk of all-cause mortality. This correlation remained significant even after adjusting for age and sex, and other factors and comorbidities that might affect outcomes (hazard ratio: 2.708, 95% CI 1.047, 7.003, p = 0.040 and 1.007; 95% CI 1.001, 1.013, p = 0.016, respectively). Furthermore, a history of diabetes mellitus was not a significant factor influencing long-term all-cause mortality. Preoperative glucose levels were found to be independently associated with survival outcomes in patients with OVCF who underwent VP. Conversely, diabetes mellitus was not associated with long-term all-cause mortality. Our findings highlight that preoperative hyperglycemia is a risk factor for long-term mortality in this aging surgical population.

ABSTRACT

Objective: To evaluate the efficacy and prognosis of percutaneous vertebroplasty/kyphoplasty (PVP/PKP) in patients with newly diagnosed multiple myeloma (NDMM). Methods: Clinical data of NDMM patients who underwent PVP/PKP during front-line regimen at Peking Union Medical College Hospital from January 1, 2003, to June 30, 2023, were analyzed. Patients with comparable bone diseases not receiving orthopedic surgery were selected as controls. Visual analogue scale (VAS) score, progression-free survival (PFS), and overall survival (OS) were compared. Results: Baseline characteristics were matched between the surgical group (n = 51 with 56 surgeries) and non-surgical group (n = 102), including demographics, tumor load, International Staging System (ISS), bone diseases, cytogenetic abnormalities, first-line treatment, and autologous stem-cell transplantation (ASCT). Bone lesions for PVP/PKP were located at thoracic vertebrae (53.6 %, 30/56) or lumbosacral vertebrae (46.4 %, 26/56). The postoperative VAS score was significantly improved (2.25 ± 0.81 vs 5.92 ± 1.05, P < 0.001). The median follow-up time was 51[38-70] months. Kaplan-Meier survival analysis suggested that both PFS (37[17-89] vs 23[12-61] months, HR 0.648, 95 %CI 0.431-0.973, P = 0.047) and OS (not reached vs 66[28-NR] months, HR 0.519, 95 %CI 0.296-0.910, P = 0.045) were significantly prolonged in the surgical group. COX multivariate analysis suggested that PVP/PKP was an independent prognostic factor for PFS (P = 0.021, HR 0.589, 95 %CI 0.376-0.922) and OS (P = 0.038, HR 0.496, 95 %CI 0.255-0.963). Subgroup analysis confirmed that patients with ISS II/III or non-ASCT achieved better PFS and OS in the surgical group (PFS: P = 0.033, P = 0.040; OS: P = 0.024, P = 0.018 respectively), while similar survival outcome was observed in patients with ISS I or ASCT between two groups. Conclusion: For NDMM patients, not only does PVP/PKP alleviate bone pain, meanwhile, it improves the PFS and OS in advanced subpopulation or non-transplant myeloma patients, which suggests that shortening the gap from symptom onset to diagnosis by orthopedic surgery favors clinical prognosis.

ABSTRACT

Background: Radiofrequency thermal ablation (RFA) coupled with vertebroplasty or kyphoplasty offers a minimally invasive, safe, and efficacious approach to palliate polymetastatic spine disease, particularly in medically fragile individuals. However, the application of robotic assistance to RFA for spinal metastases remains unexplored. This study elucidates the technical viability of robot-assisted RFA combined with vertebroplasty in patients afflicted by multiple spinal metastases and presents preliminary outcomes. An illustrative case was also presented. Materials and Methods: Ten patients aged over 65 years with multiple vertebral metastases were enrolled in this study. Preoperatively, patients exhibited a median Visual Analog Scale (VAS) pain score of 6 and a Median Oswestry Disability Index (ODI) score of 58%. From February 2021 to April 2022, all patients underwent RFA, followed by vertebroplasty for spinal metastases. Surgical procedures were executed using the ExcelsiusGPS® robotic platform. Results: Patients experienced substantial pain relief, with a median VAS score of 2.5 at 24 h postoperatively (Δ --3.5; P < 0.001) and a median VAS score of 2 at 1 month postoperatively (Δ -4; P < 0.001). All patients were discharged on the first postoperative day and continued their oncological treatments. In addition, the median ODI score at 1 month postoperatively was 34% (Δ --24%; P = 0.006), indicating an enhanced quality of life and a satisfactory impact on daily activities. No procedural or postoperative complications were documented. Conclusions: This case series represents the inaugural successful application of robot-assisted RFA in conjunction with concurrent vertebroplasty/kyphoplasty. Our preliminary experience demonstrates that patients with oligo- and polymetastatic conditions can derive benefits from this minimally invasive intervention, characterized by rapid postoperative recovery and effective short- to medium-term pain management, without encountering complications.

Purpose: To explore the rehabilitation effect and compliance of lumbar and abdominal muscle rehabilitation training in patients with osteoporotic vertebral compression fracture (OVCF) after percutaneous balloon vertebroplasty (PKP). Methods: A total 177 elderly patients with OVCF were divided into rehabilitation group (n = 104) and control group (n = 73) according to whether they received psoas and abdominal muscle rehabilitation training for 3 months after PKP. The differences of general data, orthopaedic rehabilitation, prognosis and bone metabolism were compared between the two groups. All the patients were divided into compliance group (68 cases) and non-compliance group (36 cases) according to compliance. Orthopaedic rehabilitation indicators, prognostic indicators of PKP, and bone metabolism-related parameters were collected for analysis of Chi-square test and Logistic regression. ROC curve was used to analyze the predictive value of bone metabolism related indicators in the compliance of lumbar and abdominal muscle rehabilitation training. Results: There was no significant difference in the general data between the rehabilitation training group and the control group (All p > 0.05). Compared with the control group, the Berg balance scale score was significantly increased, while the Visual Analogue Scale (VAS) score, Oswestry Disability Index (ODI) score and the proportion of new fractures were significantly decreased in the rehabilitation training group (All p < 0.05). Compared with the control group, the bone mineral density (BMD) T value, osteocalcin (OCN) and 25-hydroxyvitamin D (25 (OH) D) levels were significantly increased and the levels of type I N-propeptide (P1NP) and ß-isomerized C-terminal telopeptides (ß-CTX) were significantly decreased in the rehabilitation training group compared with the control group (All p < 0.05). Chi-square test and Logistic regression analysis showed that age > 75 years, severe anxiety, severe pain and postoperative complications were significantly associated with the compliance of psoas and abdominal muscle rehabilitation training in patients with OVCF after PKP. ROC curve analysis showed that BMD T value, OCN, P1NP, ß-CTX, or 25-OH-D levels predicted the AUC of rehabilitation training compliance in patients with OVCF after PKP were 0.821, 0.835, 0.736, 0.715, and 0.748, respectively. Conclusion: Rehabilitation training of lumbar and abdominal muscles can significantly improve the efficacy of PKP, reduce the degree of osteoporosis and improve the prognosis of patients with OVCF. Age, anxiety, pain and postoperative complications were independent risk factors affecting the compliance of psoas and abdominal rehabilitation training in patients with OVCF after PKP.

ABSTRACT

Osteoporotic vertebral fractures frequently result in pain and decreased quality of life (QoL). The management of these fractures remains a topic of debate. Following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, we analyzed randomized controlled trials comparing percutaneous vertebroplasty (PV) with non-operative treatment (non-OT). The outcomes of interest included pain, QoL, cement leakage, and new osteoporotic vertebral fractures after 1 year. Compared to non-OT regarding pain relief, PV yielded significant improvement at 1-2 weeks, 1 month, 6 months (standard mean difference [SMD] = -0.67 (6/14; 95% confidence interval [CI]: -1.29 to -0.06; I2 = 92%, random effects) and 1 year (mean difference = -1.07 (4/14; 95% CI: -1.97 to -0.18; I2 = 97%, random effects). For QoL, notable improvements were observed at 1 week (standard mean difference = -2.10 (5/14; 95% CI: -3.77 to -0.42; I2 = 98%, random effects) and 3 months (mean difference = -1.58 (4/14; 95% CI: -3.07 to -0.09; I2 = 96%, random effects), with 1 month, 6 months and 1 year being inconclusive. A cement leakage rate of 42% (10/14; 95% CI: 25% to 59%; I2 = 99%, random effects) was found. Further, PV did not significantly heighten the risk of new fractures within a year (odds ratio = 1.26 (6/14; 95% CI: 0.63 to 2.53; I2 = 74%, random effects). PV emerges as a promising intervention for specific time intervals regarding pain relief, especially in the extended-term analysis, and QoL, especially in the short-term analysis, compared to non-OT. However, clinicians must consider cement leakage risks. Heterogeneity among studies underscores careful patient selection.

ABSTRACT

Osteoporosis significantly impairs bone density and increases fracture risk, representing a substantial global health challenge. The effectiveness of traditional treatments such as calcium supplementation and exercise in completely preventing fractures is limited. This review explores recent advancements in surgical techniques and treatment modalities to manage osteoporotic fractures better and improve patient outcomes. Osteoporotic fractures demand specialized surgical techniques due to compromised bone quality. Vertebroplasty and kyphoplasty are minimally invasive procedures that provide rapid pain relief and structural support using bone cement. While vertebroplasty is effective, it carries risks of cement leakage and new fractures. Kyphoplasty, with added balloon inflation, reduces leakage risk and improves vertebral height restoration but is costlier. Cement-augmented screws enhance fixation but can increase adjacent fracture risk and pose long-term complications. Surgical advancements encompass robotic-assisted surgery, offering precision and accelerated recovery, alongside biologic agents like bone morphogenetic proteins (BMPs), which enhance bone healing while reducing secondary interventions and eliminating donor site morbidity. Bone graft substitutes such as calcium phosphate cements enhance biomechanical compatibility, decrease morbidity, and reduce fracture loss and pain. Balloon kyphoplasty aids in height restoration and pain relief and diminishes the risk of subsequent vertebral fractures. Bioglass scaffolds promote bone regeneration by improving bone mineral density and lowering the incidence of new fractures. Optimal perioperative care, including patient selection, nutritional management, and early mobilization strategies, is crucial for mitigating risks in vulnerable populations. While current surgical interventions provide significant pain relief and functional benefits, ongoing research and multidisciplinary collaboration are crucial to prospectively refine these techniques and reduce the burden of osteoporosis. New technologies, such as tissue engineering and gene editing, hold potential for future treatment paradigms.
