“…The application of expandable intravertebral implants, also known as armed kyphoplasty, in addition to allowing for the aforementioned analgesia and stabilization benefits of vertebroplasty and kyphoplasty, also theoretically enables the maintenance of restored vertebral height in the long term. This is made possible because the vertebral endplates, after their reduction, stay mechanically supported by the expanded device (they work as an interior support), which decreases or prevents vertebral flattening after expansion, reducing the risk of posttraumatic local and segmental kyphosis, and ensuring stable anterior column support at the level of the vertebral body [5,6,13,15,[23][24][25][26].…”

“…The expansion of the metallic mesh of these implants creates intrasomatic cavities by the impaction of vertebral body trabeculae. They have the advantage of creating these low-pressure areas, contained by the implant mesh surface and the impacted surrounding trabeculae, which, in theory, lowers the risk of cement leakage compared to vertebroplasty, kyphoplasty, and even other intravertebral implants that do not have this cylindrical shape [ 5 , 6 , 26 , 29 , 43 , 49 ]. However, the cavitary intrasomatic filling with cement and its containment by the cylindrical implant reduces its interdigitation in the bone trabeculae, which, in theory, can reduce the stability of the stents inside the vertebral body, and there may be a higher risk of their migration [ 5 ].…”

“…Furthermore, the expansion of the balloon enclosed by the stent ensures a uniform and more predictable cylindrical expansion than the balloon alone in kyphoplasty. In fact, the balloon alone, as it is not a rigid structure, is more likely to insinuate itself into areas of lower pressure and create an anomalous cavity, being less predictable in reducing the vertebral body [ 26 , 49 ].…”

Expandable intravertebral implants are self-expanding devices applied percutaneously by the posterior transpedicular approach. These devices introduce the concept of anatomical restoration of vertebral body endplates and direct anatomical reduction performed from the interior of the vertebral body with a compression fracture. This paper aims to provide a narrative review on the concept, indications, biomechanical characteristics, as well as functional and radiographic outcomes of the main expandable intravertebral implants currently available, in terms of their application to thoracolumbar spine traumatology. To this end, we performed a search in July 2021 on the MEDLINE/PubMed platform with the words "expandable intravertebral implant", "armed kyphoplasty", "Vertebral Body Stenting" or "stentoplasty" and "SpineJack". The search yielded 144 papers, and of those, we included 15 in this review. We concluded that percutaneous transpedicular posterior access, the ability to reduce vertebral body fractures, particularly of the vertebral endplates and to maintain the vertebral body height, makes the application of expandable intravertebral implants an attractive option in the treatment of thoracolumbar vertebral compression fractures. However, more prospective, randomized, and large-scale blinded studies are still warranted, especially comparative studies between treatments and about the preferential use of an expansive implant over others, in order to gain definitive insights into the effectiveness and indications of each of these devices.

“…However, procedural disadvantages of these surgical techniques are incomplete fracture reduction or a significant loss of the restored height after balloon deflation prior to cement injection, respectively. In order to avoid loss of height after balloon deflation, the concept of using an expandable scaffolding structure similar to vascular stents was developed [5], resulting in vertebral body stenting (VBS), utilizing a specially designed catheter-mounted stent which can be implanted extra- or transpedicularly and expanded with the use of an inflatable balloon inside the vertebral body.…”

Vertebral body stenting: a new method for vertebral augmentation versus kyphoplasty

et al. 2010

Vertebroplasty and kyphoplasty are well-established minimally invasive treatment options for compression fractures of osteoporotic vertebral bodies. Possible procedural disadvantages, however, include incomplete fracture reduction or a significant loss of reduction after balloon tamp deflation, prior to cement injection. A new procedure called “vertebral body stenting” (VBS) was tested in vitro and compared to kyphoplasty. VBS uses a specially designed catheter-mounted stent which can be implanted and expanded inside the vertebral body. As much as 24 fresh frozen human cadaveric vertebral bodies (T11-L5) were utilized. After creating typical compression fractures, the vertebral bodies were reduced by kyphoplasty (n = 12) or by VBS (n = 12) and then stabilized with PMMA bone cement. Each step of the procedure was performed under fluoroscopic control and analysed quantitatively. Finally, static and dynamic biomechanical tests were performed. A complete initial reduction of the fractured vertebral body height was achieved by both systems. There was a significant loss of reduction after balloon deflation in kyphoplasty compared to VBS, and a significant total height gain by VBS (mean ± SD in %, p < 0.05, demonstrated by: anterior height loss after deflation in relation to preoperative height [kyphoplasty: 11.7 ± 6.2; VBS: 3.7 ± 3.8], and total anterior height gain [kyphoplasty: 8.0 ± 9.4; VBS: 13.3 ± 7.6]). Biomechanical tests showed no significant stiffness and failure load differences between systems. VBS is an innovative technique which allows for the possibly complete reduction of vertebral compression fractures and helps maintain the restored height by means of a stent. The height loss after balloon deflation is significantly decreased by using VBS compared to kyphoplasty, thus offering a new promising option for vertebral augmentation.

“…The vertebral body stenting (VBS) system consists of a balloon and titanium stent, simultaneously delivered into the vertebra ( 14 ) to restore vertebral height through a transpedicular approach. After balloon retraction, the stent remains inside to maintain vertebral height ( Figures 1A–C ).…”

With increasing population aging, osteoporosis vertebral compression fractures (OVCFs), resulting in severe back pain and functional impairment, have become progressively common. Percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) as minimally invasive procedures have revolutionized OVCFs treatment. However, PVP- and PKP-related complications, such as symptomatic cement leakage and adjacent vertebral fractures, continue to plague physicians. Consequently, progressively more implants for OVCFs have been developed recently to overcome the shortcomings of traditional procedures. Therefore, we conducted a literature review on several new implants for OVCFs, including StaXx FX, Vertebral Body Stenting, Vesselplasty, Sky Bone Expander, Kiva, Spine Jack, Osseofix, Optimesh, Jack, and V-strut. Additionally, this review highlights the individualized applications of these implants for OVCFs. Nevertheless, current clinical studies on these innovative implants remain limited. Future prospective, randomized, and controlled studies are needed to elucidate the effectiveness and indications of these new implants for OVCFs.
