BACKGROUND: The KAST (Kiva Safety and Efficacy) investigation device exempt (IDE) study indicated that the majority of patients responded equally well to vertebral augmentation using either an implant-based approach or balloon kyphoplasty (BK). Additional investigation has suggested that a subset of patients may benefit further by avoiding repeated readmissions due to serious adverse events (SAEs) if they receive one vertebral augmentation approach over another. OBJECTIVES: The primary aim was to assess the effect of 2 different augmentation procedures on readmission rates for SAEs...

BACKGROUND: Burst fracture is a common thoracolumbar injury that is treated using posterior pedicle instrumentation and fusion combined with transpedicular intracorporeal grafting after reduction. In this study, we compared the outcome of these two techniques by using radiologic imaging and functional outcome. METHODS: Sixty-one patients with acute thoracolumbar burst fracture were operated with kyphoplasty (n = 31) or vertebroplasty (n = 30) and retrospectively reviewed in our institution between 2011 and 2014...

To meet the requirements of minimally invasive surgical treatments for osteoporotic vertebral compression fracture, various strategies have been proposed to enhance the properties of calcium phosphate cement (CPC). Here, a new strategy was developed by incorporating poly (γ-glutamic acid) (γ-PGA) and its strontium salt into the formulation of alpha tricalcium phosphate (α-TCP)-based CPC. Effects of γ-PGA on the injectability, cohesion, setting times, mechanical compressive strengths and cytocompatibility were systematically studied...

Vertebroplasty and kyphoplasty are minimally invasive techniques applied for the treatment of vertebral fractures. Since not all vertebral compression fractures are the same, a tailored-based approach is necessary for optimum efficacy and safety results. Nowadays, different cements and materials are proposed as alternatives to the original poly-methylmethacrylate aiming to overcome the limitations and the risks governing its use. Both techniques are governed by high efficacy and low complication rates; multilevel treatment in a single session has been shown to be feasible with no compromise of the technique's safety and efficacy...

Introduction We aim to assess the impact of the quantity of intradiscal cement leak during kyphoplasty on the rate of progression of degenerative changes in the affected disc. Methods Of 316 kyphoplasty procedures, we identified 32 episodes of intradiscal cement leak in 26 patients. The quantity of cement leaked was graded from I to IV. Disc degenerative changes were assessed at presentation and follow-up using radiographical scoring and magnetic resonance imaging (MRI) grading systems. Data for low-grade leaks (grade I) were compared with the medium- and high-grade leaks (grades II-IV) using a chi-squared test...

BACKGROUND: Posterior fixation and fusion is the primary treatment for thoracolumbar fractures, although this treatment may sacrifice range of motion (ROM) to achieve stability, rather than treating the fracture itself. Two issues addressed when treating thoracolumbar fractures include 1) replacing the fractured vertebrae, especially the upper endplate of the injured vertebrae, and 2) providing strong fixation with biomechanical stability and flexibility. METHODS: This retrospective study included 61 consecutive patients with thoracic or lumbar fractures treated from October 2010 to May 2014...

Osteoporotic vertebral fractures constitute at least 50% of the osteoporotic fractures that happen worldwide. Occurrence of osteoporotic fractures make the elderly patient susceptible for further fractures and increases the morbidity due to kyphosis and pain; the mortality risk is also increased in these patients. Most fractures occur in the thoracic and thoracolumbar region and are often stable. Different descriptive and prognostic classification systems have been described, but none are universally accepted...

We investigated the feasibility of applying polymethylmethacrylate bone cement composited with biomimetic bone-mineralizsed collagen to percutaneous kyphoplasty (PKP). We performed PKP in 95 patients diagnosed with osteoporotic vertebral compression fracture. All patients had fractures of a single vertebral body, and they were divided randomly into control (group A, 47 patients) and experimental (group B, 48 patients) groups. Patients in group A were treated with acrylic cement, and those in group B were treated with acrylic cement composited with the bone graft material...

Background Percutaneous kyphoplasty (PKP) is a common treatment modality for painful osteoporotic vertebral compression fractures (OVCFs). Pre- and postoperative identification of risk factors for cement leakage and follow-up complications would therefore be helpful but has not been systematically investigated. Purpose To evaluate pre- and postoperative risk factors for the occurrence of short-term cement leakages and long-term complications after PKP for OVCFs. Material and Methods A total of 283 vertebrae with PKP in 239 patients were investigated...

Cement augmentation via percutaneous vertebroplasty or kyphoplasty for treatment of spinal metastasis is a well-established treatment option. We assessed whether elevated intrametastatic pressure during cement augmentation results in an increased dissemination of tumour cells into the vascular circulation. We prospectively collected blood from patients with osteolytic spinal column metastases and analysed the prevalence of circulating tumour cells (CTCs) at three time-points: preoperatively, 20 minutes after cement augmentation, and 3-5 days postoperatively...

To restore damaged organ function or to investigate organ mechanisms, it is necessary to prepare replicates that follow the biological role model as faithfully as possible. The interdisciplinary field of tissue engineering has great potential in regenerative medicine and might overcome negative side effects in the replacement of damaged organs. In particular, tubular organ structures of the genitourinary tract, such as the ureter and urethra, are challenging because of their complexity and special milieu that gives rise to incrustation, inflammation and stricture formation...

BACKGROUND CONTEXT: Vertebral compression fractures are the most common type of osteoporotic fracture comprising approximately 1.4 million cases worldwide. Clinical practice guidelines can be powerful tools for promoting evidence-based practice, as they integrate research findings in order to support decision-making. However, currently available clinical guidelines and recommendations, established by different medical societies, are sometimes contradictory. PURPOSE: The aim of this study was to appraise the recommendations and methodological quality of international clinical guidelines for the management of VCFs...

Thoracolumbar vertebral fracture incidents usually occur secondary to a high velocity trauma in young patients and to minor trauma or spontaneously in older people.Osteoporotic vertebral fractures are the most common osteoporotic fractures and affect one-fifth of the osteoporotic population.Percutaneous fixation by 'vertebroplasty' is a tempting alternative for open surgical management of these fractures.Despite discouraging initial results of early trials for vertebroplasty, cement augmentation proved its superiority for the treatment of symptomatic osteoporotic vertebral fracture when compared with optimal medical treatment...
