BACKGROUND CONTEXT: Proximal junctional kyphosis (PJK) and proximal junctional failure (PJF) are common problems after long segment (>5 levels) thoracolumbar instrumented fusions in the treatment of adult spinal deformity (ASD). No specific surgical strategy has definitively been shown to lower the risk of PJK as the result of a multifactorial etiology. PURPOSE: To assess the incidence of PJK and PJF in patients treated with prophylactic polymethylmethacrylate(PMMA) cement augmentation at the uppermost instrumented vertebrae(UIV) and rostral adjacent vertebrae(UIV+1)...

The relative efficacy and harms of balloon kyphoplasty (BK) for treating vertebral compression fractures (VCF) are uncertain. We searched multiple electronic databases to March 2016 for randomised and quasi-randomised controlled trials comparing BK with control treatment (non-surgical management [NSM], percutaneous vertebroplasty [PV], KIVA®, vertebral body stenting, or other) in adults with VCF. Outcomes included back pain, back disability, quality of life (QoL), new VCF and adverse events (AE). One reviewer extracted data, a second checked accuracy, and two rated risk of bias (ROB)...

BACKGROUND CONTEXT: The incidence of proximal junctional kyphosis (PJK) ranges from 5-46% following adult spinal deformity (ASD) surgery. Approximately 66-76% of PJK occurs within 3 months of surgery. A subset of these patients, reportedly 26-47%, develop proximal junctional failure (PJF) within 6 months postoperatively. To date, there are no studies evaluating the impact of prophylactic vertebroplasty on PJK/PJF incidence at long term follow-up. PURPOSE: The purpose of this study is to evaluate the long term radiographic and clinical outcomes, and incidence of PJK and PJF, after prophylactic vertebroplasty for long segment thoracolumbar posterior spinal fusion...

Calcium phosphate cements are osteoconductive biomaterials that are widely used for bone repair and regeneration applications, including spinal fusion, vertebroplasty, khyphoplasty, cranioplasty and periodontal surgeries. The flow and deformation behavior (rheology) and injectability of the calcium phosphate bone cements to the treatment site are governed by the setting kinetics of the cement during which the initially flowable, viscous cement paste transforms into a rigid elastic solid. Here time-dependent development of the linear viscoelastic properties of a brushite-forming calcium phosphate cement are characterized and linked to the mechanism and kinetics of the setting reaction and to the injectability window available during the surgical applications of the cement...

Advances in cancer treatments have lengthened the survival of patients with bone metastases. Optimal control of the symptoms and prevention of the complications associated with bone metastases improve quality of life. Achieving these goals increasingly involves interventional radiology procedures. These include bone consolidation and analgesic techniques such as cementoplasty (vertebroplasty at the spine); percutaneous implantation of screws, metallic reinforcement devices, or intraosseous implants; and tumor destruction using thermal methods (radiofrequency and cryotherapy), chemicals (alcohol), and drugs (chemoembolization), which have fewer indications...

AIM: Anti-osteoporotic therapy requires years of proper compliance to reduce the risk of fractures. This study investigated the effects of 1st-year adherence to anti-osteoporotic treatment on the risk of mortality in patients with magnetic resonance imaging-proven acute osteoporotic vertebral fractures after vertebroplasty. PATIENTS AND METHODS: This retrospective study included 294 patients (252 females; mean age, 73.93±7.18 years) with osteoporosis and acute vertebral fractures treated with vertebroplasty between January 2001 and December 2007...

BACKGROUND CONTEXT: Whether early vertebroplasty (VP) (within 3 months) offers extra benefit to aged patients older than 70 years with painful vertebral compression fractures (PVCF) in terms of mortality and respiratory-related morbidity remains unknown, given that the elderly is associated with higher surgical risks. PURPOSE: To elucidate the benefits of an early VP intervention for aged patients with a PVCF by comparing the risks of mortality and respiratory-related morbidity...

Patients with metastatic spinal disease are affected by disabling pain. The treatment of spinal metastases is focused on pain reduction and improvement in quality of life. Until recently, many patients with metastatic spinal disease did not qualify as surgical candidates due to the risks of surgery and length of recovery period. However, recent advances in minimally invasive surgery such as kyphoplasty and vertebroplasty allow patients to safely undergo surgery for pain relief with a short recovery period. The studies reviewed here suggest that vertebral augmentation is successful in reducing pain and disability scores in patients with painful metastases and multiple myeloma and are a safe modality to provide lasting pain relief...

Cement augmentation in vertebrae (vertebroplasty) is usually used to restore mechanical strength after spinal fracture but could also be used as a prophylactic treatment. So far, the mechanical competence has been determined immediately post-treatment, without considering long-term effects of bone adaptation. In this work, we investigated such long-term effects of vertebroplasty on the stiffness of the augmented bone by means of computational simulation of bone adaptation. Using micro-finite element analysis, we determined sites of increased mechanical stress (stress raisers) and stress shielding and, based on the simulations, regions with increased or decreased bone loss due to augmentation...

The combination of percutaneous vertebroplasty with radiofrequency ablation (verteblation) has not shown to be an effective measure of pain management in patients with metastatic lesions of the spine. The use of this novel technique has not been previously described in metastatic disease from thyroid cancer. We would like to report our experience after treating a patient affected by a thyroid carcinoma and an osteolytic spine metastasis. The patient suffered from life-limiting pain and was successfully treated with a combination of vertebroplasty and radiofrequency ablation...

Vertebral hemangiomas are the most common benign vertebral neoplasms and are generally asymptomatic. In the present study, we report the case of a 52-year-old male master ultra-marathoner suffering from a pathologic fracture of the thoracic spine due to a vertebral hemangioma. A further examination in the athlete revealed an accompanying osteopenia, which was most likely due to a deficiency in both vitamin D and testosterone. The treatment of the fracture consisted of percutaneous vertebroplasty. Shortly after the operation the athlete was able to continue running...

Hemangiomas are benign tumors, which are mainly composed of neoplastic blood vessels. The exact pathogenesis is still unclear. They are the most common benign spinal tumors and also occur less commonly in the bones of the extremities. Hemangiomas are often clinically asymptomatic and are diagnosed as incidental findings. Women are affected more frequently than men (2:1). The X‑ray and computed tomography (CT) diagnostics typically demonstrate the classical honeycombing or vertically orientated lucencies separated by thickened cancellous bone in the affected skeletal section...

Tobias A Mattei
BACKGROUND: Previous studies have demonstrated lower rates of cement extravasation when comparing balloon kyphoplasty with vertebroplasty, an effect attributed to the low-pressure injection. However, in patients with isolated endplate fractures, balloon kyphoplasty may lead to further endplate damage and increased risks of intradiscal extravasation. METHODS: The author provides a stepwise description of a new technique called cavitational kyphoplasty that allows targeted low-pressure cement injection without the necessity of balloon inflation...
