Osteoporotic vertebral fractures often lead to pain and disability. They can be successfully treated, and possibly prevented, by injecting cement into the vertebral body, a procedure known as vertebroplasty. Kyphoplasty is similar, except that an inflatable balloon is used to restore vertebral body height before cement is injected. These techniques are growing rapidly in popularity, and a great deal of recent research, reviewed in this paper, has examined their ability to restore normal mechanical function to fractured vertebrae. Fracture reduces the height and stiffness of a vertebral body, causing the spine to assume a kyphotic deformity, and transferring load bearing to the neural arch. Vertebroplasty and kyphoplasty are equally able to restore vertebral stiffness, and restore load sharing towards normal values, although kyphoplasty is better at restoring vertebral body height. Future research should optimise these techniques to individual patients in order to maximise their beneficial effects, while minimising the problems of cement leakage and adjacent level fracture.

Osteoporotic Vertebral Fractures

Abstract Changes in vertebral body height depend on various factors which were analyzed in isolation and not as a whole. The aim of this study is to analyze what factors might influence restoration of vertebral body height after vertebral augmentation. We analyzed 48 patients (108 vertebrae) with osteoporotic vertebral fractures underwent vertebral augmentation when conservative treatment proved unsatisfactory. Analyses were carried out at the time of the fracture, during surgery (pre-cementation and post-cementation), at first medical check-up (6 weeks post-surgery) and at last medical check-up. Average vertebral height was measured and differences from preoperative values calculated at each timepoint. Pearson correlation coefficient and linear multivariable regression were carried out at the different timepoints. The time since vertebral fracture was 60.4 ± 41.7 days. Patients’ average age was 70.9 ± 9.3-years. The total follow-up was 1.43 ± 1-year. After vertebral cementation there was an increase in vertebral body height of + 0.3cm (13.6%). During post-operative follow-up, there was a progressive collapse of the vertebral body and pre-surgical height was reached. The factors that most influenced vertebral height restoration were: grade III collapse, intervertebral-vacuum-cleft (IVVC), and use of a flexible trocar before cement augmentation. The factor that negatively influenced vertebral body height restoration was location in the thoracolumbar spine.

OBJECTIVEIntravertebral augmentation (IVA) is a reliable minimally invasive technique for treating Magerl type A vertebral body fractures. However, poor correction of kyphotic angulation, the risk of cement leakage, and significant exposure to radiation (for the surgeon, the operating room staff, and the patient) remain significant issues. The authors conducted a study to assess the value of robot-assisted IVA (RA-IVA) for thoracolumbar vertebral body fractures.METHODSThe authors performed a retrospective, single-center study of patients who had undergone RA-IVA or conventional fluoroscopy-guided IVA (F-IVA) for thoracolumbar vertebral body fractures. Installation and operating times, guidance accuracy, residual local kyphosis, degree of restoration of vertebral body height, incidence of cement leakage, rate of morbidity, length of hospital stay, and radiation-related data were recorded.RESULTSData obtained in 30 patients who underwent RA-IVA were compared with those obtained in 30 patients who underwent F-IVA during the same period (the surgical indications were identical, but the surgeons were different). The mean ± SD installation time in the RA-IVA group (24 ± 7.5 minutes) was significantly shorter (p = 0.005) than that in the F-IVA group (26 ± 8 minutes). The mean operating time for the RA-IVA group (52 ± 11 minutes) was significantly longer (p = 0.026) than that for the F-IVA group (30 ± 11 minutes). All RA-IVAs and F-IVAs were Ravi’s scale grade A (no pedicle breach). The mean degree of residual local kyphosis (4.7° ± 3.15°) and the percentage of vertebral body height restoration (63.6% ± 21.4%) were significantly better after RA-IVA than after F-IVA (8.4° ± 5.4° and 30% ± 34%, respectively). The incidence of cement leakage was significantly lower in the RA-IVA group (p < 0.05). The mean length of hospital stay after surgery was 3.2 days for both groups. No surgery-related complications occurred in either group. With RA-IVA, the mean radiation exposure was 438 ± 147 mGy × cm for the patient and 30 ± 17 mGy for the surgeon.CONCLUSIONSRA-IVA provided better vertebral body fracture correction than the conventional F-IVA. However, RA-IVA requires more time than F-IVA.

BACKGROUND: There are controversies about the optimal management of AO subtype A3 burst fractures. The most common surgical treatment consists of posterior fixation with pedicle screw and rod augmentation. Nevertheless, a loss of correction in height restoration and kyphotic reduction has been observed. OBJECTIVES: The aim of this study was to assess long-term outcomes of a minimally invasive technique using a percutaneous intravertebral expandable titanium implant (PIETI). STUDY DESIGN: This prospective, single center, pilot study was carried out on a consecutive case series of 44 patients with acute (< 2 weeks) traumatic thoracolumbar fractures AO type A3. The average follow-up was 5.6 years. SETTING: A single center in Castilla y Leon, Spain METHODS: Clinical outcomes (pain intensity on visual analog scale [VAS], Oswestry Disability Index [ODI], analgesic consumption) and radiographic outcomes (anterior/mid/posterior vertebral body height, vertebral area, local kyphosis angle, traumatic regional angulation) were analyzed before surgery, at one month after surgery, and at the end of the follow-up period. RESULTS: At one-month postsurgery, significant improvements in VAS score and ODI score were observed. PIETI achieved significant vertebral body height restoration with median height increases of 2.9 mm/4.3 mm/2.3 mm for anterior/middle/posterior parts, respectively. Significant correction of the local kyphotic angle and improvement of the traumatic regional angulation were accomplished. All these improvements were maintained throughout the follow-up period. The only complication reported was a case of cement leakage. LIMITATIONS: In our opinion, the main limitation of the study is the small number of patients. However, the sample is superior to that shown in other papers. CONCLUSIONS: This study showed that using a PIETI in the treatment of fractures type A3 is a safe and effective method that allows marked clinical improvement, as well as anatomical vertebral body restoration. Unlike with other treatments, results were maintained over time, allowing a better long-term clinical and functional improvement. The rate of cement leakage was lower than other reports.

Study Design: Retrospective cohort study. Objectives: The OF classification is a new classification for osteoporotic vertebral fractures. The aim of this study was to clarify the relationship between preoperative OF subgroups and the postoperative outcome after kyphoplasty in patients with such fractures. Methods: Patients who underwent kyphoplasty of a single osteoporotic vertebral fracture were included and divided into groups according to the OF subgroups. Pre- and postoperative plain radiographs were analyzed in regard to the restoration of vertebral body height and local kyphotic angle (LKA). Additionally, clinical data including pre- and postoperative Visual Analogue Scale pain scores was documented. The clinical and radiological results were compared pre- and postoperatively within groups and between groups. Results: A total of 156 patients from OF subgroups 2 to 4 were included (OF 2: n = 58; OF 3: n = 36; OF 4: n = 62). Patients from all groups experienced significant pain relief postoperatively ( P < .001). Patients with OF 2 fractures showed a repositioning of the vertebral body height in the anterior and middle portions (both P < .001), but no significant improvement in LKA. For OF 3 and 4 fractures, there was a significant restoration of vertebral body height ( P < .001 for both) and a significant improvement of LKA ( P < .001 for both). The highest average restoration was noted in the OF 4 group. Conclusions: A higher OF subgroup is related to a higher radiological benefit from kyphoplasty. This confirms that the OF classification is an appropriate tool for the preoperative assessment of osteoporotic fractures.

Abstract Objective: to investigate the effect of CT-assisted limited decompression in the management of single segment A3 lumbar burst fracture. Method: A retrospective study of 106 cases with a single-level Magerl type A3 lumbar burst fractures treated with short-segment posterior internal fixation and limited decompression from January 2015 to June 2019 was performed. Patients were divided into two groups: CT-assisted and non-CT-assisted. Perioperative factors, clinical outcomes, postoperative complications, imaging parameters and health-related quality of life (HRQoL) were evaluated. Results: There was no significant difference between the two groups in the kyphosis, anterior vertebral body height loss, posterior vertebral body height loss, operative time, and postoperative complications. The visual analogue score (VAS) and spinal canal encroachment in the CT-assisted group were lower than those in the non-CT-assisted group (P < 0.05). The Japanese Orthopaedic Association score (JOA), the simplified HRQoL scale and American Spinal Injury Association (ASIA) Spinal Cord Injury Grade in the CT-assisted group were higher than those in the non-CT-assisted group (P < 0.05).Conclusion: CT-assisted limited decompression in the treatment of single-segment A3 lumbar burst fracture can achieve better fracture reduction and surgical results, and improve the long-term recovery of neurological function and quality of life of the patients.

Abstract Background: There is no consensus on the best choice between high- and low-viscosity bone cement for percutaneous vertebroplasty (PVP). This study aimed to compare the clinical outcomes and leakage between three cements with different viscosities in treating osteoporotic vertebral compression fractures.Methods: This is a prospective study comparing patients who were treated with PVP: group A (n = 99, 107 vertebrae) with high-viscosity OSTEOPAL V cement, group B (n = 79, 100 vertebrae) with low-viscosity OSTEOPAL V cement, and group C (n = 88, 102 vertebrae) with low-viscosity Eurofix VTP cement. Postoperative pain severity was evaluated using the visual analog scale. Cement leakage was evaluated using radiography and computed tomography.Results: There was no significant difference in the incidence of cement leakage between the three groups (group A 20.6%, group B 24.2%, group C 20.6%, P = 0.767). All three groups showed significant reduction in postoperative pain scores but did not differ significantly in pain scores at postoperative 2 days (group A 2.01 ± 0.62, group B 2.15 ± 0.33, group C 1.92 ± 0.71, P = 0.646). During the 6 months after cement implantation, significantly less reduction in the fractured vertebral body height was noticed in group B and group C than in group A (group A 19.0%, group B 8.1%, group C 7.3%, P = 0.009).Conclusions: Low-viscosity cement has comparable incidence of leakage compared to high-viscosity cement in PVP for osteoporotic vertebral compression fractures. It also can better prevent postoperative loss of vertebral body height.

Abstract Background The clinical efficacy of vertebroplasty and kyphoplasty treating osteoporotic vertebral compression fractures (OVCF) has been widely recognized in recent years. However, there are also disadvantages of bone cement leakage (BCL), limited correction of kyphosis and recovery of vertebral height. Nowadays, in view of these shortcomings, vesselplasty has been widely used in clinical practice. The objective of this study is to assess its clinical effect and application value for the treatment of OVCF with peripheral wall damage. Methods/Design: All 62 patients (70 vertebrae) treated for OVCF with peripheral wall damage using vesselplasty were involved and retrospectively analyzed. The data collection included operation time, volume of bone cement, relevant surgical complications, visual analog scale (VAS), Oswestry disability index (ODI), vertebral body height and kyphosis Cobb angle. Results The time of operation was 20–65 (34.5 ± 10.5) minutes. The volume of bone cement was 3–8 (5.3 ± 1.3) ml. VAS and ODI at different time points after operation were decreased compared with before operation (all P < 0.05). There were no statistical differences between VAS or ODI at different postoperative time points (P > 0.05). Vertebral body height and Cobb angle at different time points after operation were improved compared with before operation (all P < 0.05). There were no statistical differences between vertebral body height or Cobb angle at different postoperative time points (all P > 0.05). Conclusion Vesselplasty can reduce the risk of BCL and better control the dispersion of bone cement in the treatment of OVCF. It has a definite effect in relieving pain, restoring the vertebral body height and correcting the kyphosis caused by injured vertebrae, especially in OVCF with peripheral wall damage. Therefore, vesselplasty is safe and worthy of clinical application.

Background Percutaneous vertebral augmentation (PVA) is widely applied for the treatment of osteoporotic vertebral fractures. The degree of vertebral body height restoration and deformity correction after the procedure is not consistent. Methods We retrospectively reviewed 97 patients who underwent PVA, because of osteoporotic vertebral compression fractures. The following data about the patients were recorded: age, sex, bone density, number of treated vertebrae, severity of fracture of the treated vertebrae, operative approach (PVP or PKP), volume of injected bone cement, preoperative vertebral compression ratio, preoperative local kyphosis angle, cement leakage, postoperative vertebral body height restoration ratio, follow-up period, and latest follow-up height loss ratio. Bivariate regression analysis and t-test were applied for univariate analysis, while multivariate linear regression analysis was applied for multivariate analysis. Results The postoperative vertebral body height restoration ratio was (14.7% ± 15.2%), and the last follow-up height loss ratio was (13.5% ± 11.5%). The multivariate analysis showed that the number of treated vertebrae, preoperative vertebral compression ratio, and preoperative local kyphosis angle are the main factors influencing the postoperative vertebral body height restoration. The univariate analysis also showed that only the postoperative vertebral body height restoration ratio is related to the last follow-up height loss ratio. Conclusions The number of treated vertebrae, preoperative vertebral compression ratio, and preoperative local kyphosis angle are the main influencing factors of patients' vertebral body height restoration after PVA, and the postoperative vertebral body height restoration ratio is the main factor influencing the last follow-up height loss ratio.
