BACKGROUND. Osteoporosis with subsequent osteoporotic vertebral compression fractures is an increasingly important disease due not only to its significant economic impact but also to the increasing age of our population. Pain reduction and stabilization are of primary importance with osteoporotic vertebral compression fractures. OBJECTIVE. To compare the efficacy and safety of balloon kyphoplasty and vertebroplasty for the treatment of vertebral compression fractures. MATERIALS & METHODS. From January 2004 to December 2009, 142 patients (32 males and 110 females), from 54 to 84 years old (mean age 67.4) were treated for 185 osteoporotic vertebral fractures of the thoracic or lumbar spine (level of fracture at Th5 or lower), with back pain for more than 8 weeks, and a visual analogue scale (VAS) score of 5 or more. Twenty-two patients (29 fractures) were lost at follow-up period and excluded. Patients were randomly allocated to percutaneous kyphoplasty (64%) or vertebroplasty (36%). All fractures were analyzed for improvement in sagittal alignment (Cobb angle, kyphotic angle, sagittal index, vertebral height). The patients were evaluated using the visual analog scale (VAS) and the Oswestry Disability Score. Radiographs were performed postoperatively, and at 1, 3, 6, and 12 months. RESULTS. The score according to pain, the patient's ability to ambulate independently and without difficulty, and the need for medications improved significantly (P < 0.001) after kyphoplasty or vertebroplasty. No significant difference could be found between both groups for the mean VAS and ODI preoperative and postoperative. Vertebral body height and kyphotic wedge angle of the T-L spine were also improved (p < 0.001); although kyphosis correction seems to be improved better in kyphoplasty than vertebroplasty. The rate of leakage was 12% for kyphoplasty and 32% for vertebroplasty; nevertheless most of the leakage was clinically asymptomatic and the rate of serious problems remained low (pulmonary embolism 0.01% kyphoplasty vs 0.6% vertebroplasty). New fractures in the next 6 months at the adjacent vertebrae were observed ∼ 15% in both groups. More PMMA was used in the kyphoplasty group than in the vertebroplasty group (5.5 +/− 0.8 vs. 4.1 +/− 0.5 mL, p < 0.001). Operation time was longer in balloon kyphoplasty compared to vertebroplasty (mean time 20±5min/vertebral fracture in group B vs 30±5min in group A). CONCLUSION. Both balloon kyphoplasty and vertebroplasty provided a safe and effective treatment for pain and disability in patients with vertebral compression fractures due to trauma or osteoporosis. Balloon kyphoplasty led to an ongoing reduction of fractured vertebrae and was followed by a lower rate of cement leakage

BACKGROUND CONTEXT. Osteoporosis causes decreased bone mineral density, which predisposes to fragility fractures. Low-energy vertebral compression fractures are the most common type of osteoporotic fragility fracture. Prior studies have shown that only one-quarter of patients diagnosed with an osteoporotic fracture are referred or treated for osteoporosis. PURPOSE. To identify the rate of recurrent fractures after vertebroplasty and after the conservative treatment for patients aged 50 years and older who sustained low impact vertebral compressions fractures over a 6-month period. STUDY DESIGNED/SETTING. Prospective study. PATIENT SAMPLE. The sample included patients 50 years or older who had a low-energy vertebral compression fracture. The patients were divided into two groups: first group (n=24) - patients teated by vertebroplasty and the second group (n=34) - patients treated conservatory. There was no significant difference among the groups in terms of the vertebral levels or BMD. METHODS. Patients records were reviewed for fracture recurrence and in the same time we examined medical records for osteoporotic medication prescriptions, refferals to endocrinology and to dual-energy X-ray absorptiometry (DEXA) scans. RESULTS. Confounding factors of age at the procedure, sex and chronic steroids use were considered and found to have no statistically significant difference between the two groups and between those with fracture recurrence and those without fracture recurrence. Four vertebroplasty procedure resulted in a recurrent fracture within the first 6 months. In the patient group treated conservatory 8 patients sustained recurrent fractures. Patients with recurrent vertebral fracture didn't receive active osteoporosis treatment. Within 6 months after the fracture only 21% of patients were receiving active osteoporosis treatment. CONCLUSIONS. The incidence of recurrent fracture after vertebroplasty or after conservative treatment is substantial but have no statistically significant difference between the two groups. We consider that the recurrence rate is not related with the surgical intervention but is the result of natural history of the patient's osteoporosis because the patients do not understand the importance of initiating active therapeutic intervention for osteoporosis recommended by physicians

Introduction. The risk factors for new adjacent vertebral compression fracture (NAVCF) after Vertebroplasty (VP) or Kyphoplasty (KP) for osteoporotic vertebral compression fractures (VCFs) were investigated. Materials and methods. The authors retrospectively analyzed the incidence of NAVCFs in 135 patients treated with VP or KP for osteoporotic VCFs. Study period was from 2004 to 2008 with minimum follow-up of 2 years. Possible risk factors were documented: age, gender, body mass index, bone mineral density (BMD), co-morbidities, location of treated vertebra, treatment modality and amount of bone cement injected. Anterior-posterior vertebral body height ratio, intra-discal cement leakage into the disc space and pattern of cement distribution of the initial VCF and adjacent vertebral bodies were assessed on lateral thoracolumbar radiographs by 2 independent assessors. Results. 21 patients (15.6%) had subsequent symptomatic NAVCFs with a median time to new fracture was of 125 days. There was no difference in incidence of NAVCF between VP and KP groups (P>0.05). Significant differences were found between patients with and without NAVCF in terms of age, BMD, and the proportion of cement leakage into the disc space (P < 0.05). Greater age, intra-discal cement leakage and low BMD were found in patients with NAVCF. Conclusion. The most important risk factors affecting NAVCFs were age, osteoporosis and intra-discal cement leakage

Objective

Comparison of clinical outcome after Percutaneous Vertebro Plasty (PVP) for Osteoporotic Vertebral Compression Fractures (OVCFs) between patients with and without Intra Vertebral Clefts (IVCs).

Introduction

This study compares outcomes of vertebroplasty(VP) and kyphoplasty(KP) in 125 consecutive female Asian patients above 65 years with L1 osteoporotic vertebral compression fractures

Purpose. Assessment of effectiveness of spinal fixation in conditions of general osteoporosis. Material and methods of studies. 112 patients with multiple osteoporotic pathological vertebral body fractures were surgically treated. Multilevel laminar or transpedicular instrumentation with or without ventral stabilization (group A) was used on 64 of them. The cemented polyaxial screws were used in 48 cases (group B). The patients treated with multilevel transpedicular fixation with cemented screws were included in B-I subgroup. The patients treated with monosegmental fixation (around fractures) with same screws were included in B-II subgroup. The parameters of stability (bone resorption around screws and cement, dislocation of implants, clinical symptoms) were studied in both groups. Outcome results and discussion: In group “A” the parameters of stability were the purest. The displacement of instrumentation with lost of correction has been revealed in 21% of cases. The reoperations were done in 17% of them. In groups B-I and B-II the parameters of stability were the same. There were no clinical signs of instability up to2 years of supervision. In 75% of cases the bone resorption around bone cement has been revealed after 3–6 months. But there were no cases of instrumental displacement. Spinal fixation in treatment of multiple pathological vertebral body fractures in conditions of general osteoporosis using the vertebroplasty with cemented screws provide good stability of the spine for long outcome. This method allows to achieve the clinical result with less invasive approach by shortening of extent of fixation

We reviewed 59 bone graft substitutes marketed by 17 companies currently available for implantation in the United Kingdom, with the aim of assessing the peer-reviewed literature to facilitate informed decision-making regarding their use in clinical practice. After critical analysis of the literature, only 22 products (37%) had any clinical data. Norian SRS (Synthes), Vitoss (Orthovita), Cortoss (Orthovita) and Alpha-BSM (Etex) had Level I evidence. We question the need for so many different products, especially with limited published clinical evidence for their efficacy, and conclude that there is a considerable need for further prospective randomised trials to facilitate informed decision-making with regard to the use of current and future bone graft substitutes in clinical practice.
