INTRODUCTION: In reviewing a larger group of osteoporotic vertebral compression fractures (VCFs), we found that the overall incidence of sacral insufficiency fractures (SIFs) is higher than commonly reported values. This is especially seen in patients with previous or concurrent lumbar VCFs and also in a subgroup that had lumbar stenosis or hip arthroplasty. The altered biomechanics due to associated lumbar stenosis or hip arthroplasty lead to increased mechanical stress on already weakened and deficient sacral alae, which are more vulnerable to osteoporotic weakening than other parts of the sacrum...

BACKGROUND: Osteoporotic vertebral compression fracture (OVCF) afflicts most aged people, Except for conservative therapy (CT), percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) are another two the common choices, but current evaluation of their efficacy is not performed. METHODS: All the trial data were originated from electronic database including PubMed, Embase and Cochrane Library. Four indicators with mean difference (MD) or odd ratio (OR) with their 95% credible interval (95% CrI) were analyzed to evaluate the efficacy, including the value of visual analogue scale (VAS), Oswestry disability index (ODI), relieving kyphotic angle (KA) and rate of fracture...

Case 1. A 35-year-old woman in the 8(th) month of her first pregnancy suffered acute lumbar pain that persisted for 4 months. In the 5(th) month postpartum an acute increase in the low back pain led to a MRI which showed recent deformity in L1 and deformities of undetermined time of evolution in L2, L4, and L5. Laboratory evaluation did not reveal metabolic derangements. She had low bone mineral density (BMD, DXA) and severe deterioration of the microarchitecture of distal appendicular bone (HR-pQCT). Kyphoplasty of all 4 vertebrae was performed in 2 stages, and treatment with subcutaneous denosumab, 60 mg every 6 months, was begun...

BACKGROUND: Cement leakage is the most common complication of vertebroplasty and kyphoplasty. So far, the reported risk factors remain conflicting due to limited data and lack of uniform measurement and evaluation. Here, we aimed to perform a systematic review and meta-analysis of potential risk factors for cement leakage after vertebroplasty or kyphoplasty. METHODS: Relevant literature was retrieved using PubMed, EMBASE, Cochrane Controlled Trial Register and MEDLINE with no language restriction, supplemented by a hand-search of the reference lists of selected articles...

BACKGROUND: Although percutaneous kyphoplasty (PKP) could achieve rapid pain relief for the elderly with osteoporotic vertebral compression fracture (OVCF), some patients still had risks of suffering vertebrae delayed union which led to persisting pain and vertebral collapse. Preventing the delayed vertebral union could reduce the further morbidities and medical costs for patients with OVCF after PKP. OBJECTIVES: To explore the factors involved in delayed vertebral union after PKP in patients with OVCF...

INTRODUCTION: Management of patients with poor bone stock remains difficult due to the risks of mechanical complications such as screws pullouts. At the same time, development of minimal invasive spinal techniques using a percutaneous approach is greatly adapted to these fragile patients with a reduction in operative time and complications. The aim of this study was to report our experience with cemented percutaneous screws in the management of patients with a poor bone stock. METHODS: Thirty-five patients were included in this retrospective study...

BACKGROUND: Painful spinal metastases usually occur in malignant neoplastic disease. Treatment for bone metastases has been largely conservative, and it includes the use of high doses of analgesics, radiotherapy, chemotherapy, hormone therapy, and bisphosphonates; however, results are sometimes transient and ineffective. In the presence of neurological involvement a surgical strategy should be considered. Recently, percutaneous procedures such as radiofrequency ablation, vertebroplasty, and kyphoplasty have been introduced as palliative techniques to treat painful vertebral metastases [3, 11, 25]...

STUDY DESIGN: An in vitro biomechanical study. OBJECTIVE: To determine the fracture reduction achieved by a novel inflatable bone tamp under simulated physiological load. SUMMARY OF BACKGROUND DATA: Previous biomechanical studies have showed that kyphoplasty allows near-total restoration of lost vertebral height in unloaded conditions and partial height restoration under simulated physiological loads. Clinically, loss of reduction has been observed after bone tamp deflation, before cement injection...

PURPOSE: Percutaneous kyphoplasty (PKP) is a minimally invasive procedure for the treatment of osteoporotic vertebral compression fractures (OVCFs). It is generally considered that there is little blood loss during the surgery. However, a significant perioperative hidden blood loss (HBL) is neglected. This study was to examine the amount of HBL and determine the influential factors during PKP. METHODS: From January 2015 to January 2016, 115 patients with OVCFs who were scheduled to have a PKP were enrolled in this study...

INTRODUCTION: There is still no general consensus about the management of osteoporotic vertebral fractures. Recommendations depend on type of fracture, grade of instability, bone quality, and general conditions of the patient. Spontaneous fractures may be considered to be treated different compared to cases with high-velocity trauma. METHODS: According to the DVO, patients without trauma should first be treated conservatively. However, there is no more strict time protocol of 3 or 6 week conservative treatment before operations may be indicated...

Unstable vertebral body fragility fractures of the thoracolumbar spine can occur with or without relevant trauma. Initially, a standardized diagnostic algorithm including magnetic resonance tomography is recommended to detect accompanied further vertebral body fractures, to interpret the individual fracture stability, and to screen for relevant traumatic intervertebral disc lesions. Aim of the therapy is to assure fast mobilization and to maintain spinal alignment. Unstable fracture morphology is defined by vertebral body fractures including a relevant defect of the posterior vertebral cortex as well as type B or C fractures...
