Zoledronate administered every 12 to 18 months prevents fractures in older women. Ten years after initiation of this trial, zoledronate administered at baseline and 5 years prevented vertebral fracture.

Treatments for postmenopausal women with osteoporosis include estrogens, selective estrogen-receptor modulators, bisphosphonates, calcitonin, vitamin D, and calcitriol. These treatments reduce bone resorption (and formation) and moderately increase bone density; some agents reduce the risk of fracture, but none routinely restore normal bone mass or strength. Treatments that stimulate bone formation may overcome these limitations. Parathyroid hormone stimulates bone formation and resorption and can increase or decrease bone mass, depending on the mode of administration. Continuous infusions and daily subcutaneous injections of parathyroid hormone stimulate bone formation similarly but have different effects on bone resorption and bone mass. 1 , 2 Continuous infusions, . . .

Non-randomised trials have reported benefits of kyphoplasty in patients with cancer and vertebral compression fractures (VCFs). We aimed to assess the efficacy and safety of balloon kyphoplasty compared with non-surgical management for patients with cancer who have painful VCFs. The Cancer Patient Fracture Evaluation (CAFE) study was a randomised controlled trial at 22 sites in Europe, the USA, Canada, and Australia. We enrolled patients aged at least 21 years who had cancer and one to three painful VCFs. Patients were randomly assigned by a computer-generated minimisation randomisation algorithm to kyphoplasty or non-surgical management (control group). Investigators and patients were not masked to treatment allocation. The primary endpoint was back-specific functional status measured by the Roland-Morris disability questionnaire (RDQ) score at 1 month. Outcomes at 1 month were analysed by modified intention to treat, including all patients with data available at baseline and at 1 month follow-up. Patients in the control group were allowed to crossover to receive kyphoplasty after 1 month. This study is registered with ClinicalTrials.gov, NCT00211237. Between May 16, 2005, and March 11, 2008, 134 patients were enrolled and randomly assigned to kyphoplasty (n=70) or non-surgical management (n=64). 65 patients in the kyphoplasty group and 52 in the control group had data available at 1 month. The mean RDQ score in the kyphoplasty group changed from 17·6 at baseline to 9·1 at 1 month (mean change −8·3 points, 95% CI −6·4 to −10·2; p<0·0001). The mean score in the control group changed from 18·2 to 18·0 (mean change 0·1 points; 95% CI −0·8 to 1·0; p=0·83). At 1 month, the kyphoplasty treatment effect for RDQ was −8·4 points (95% CI −7·6 to −9·2; p<0·0001). The most common adverse events within the first month were back pain (four of 70 in the kyphoplasty group and five of 64 in the control group) and symptomatic vertebral fracture (two and three, respectively). One patient in the kyphoplasty group had an intraoperative non-Q-wave myocardial infarction, which resolved and was attributed to anaesthesia. Another patient in this group had a new VCF, which was thought to be device related. For painful VCFs in patients with cancer, kyphoplasty is an effective and safe treatment that rapidly reduces pain and improves function. Medtronic Spine LLC.

Percutaneous vertebroplasty is increasingly used for treatment of pain in patients with osteoporotic vertebral compression fractures, but the efficacy, cost-effectiveness, and safety of the procedure remain uncertain. We aimed to clarify whether vertebroplasty has additional value compared with optimum pain treatment in patients with acute vertebral fractures. Patients were recruited to this open-label prospective randomised trial from the radiology departments of six hospitals in the Netherlands and Belgium. Patients were aged 50 years or older, had vertebral compression fractures on spine radiograph (minimum 15% height loss; level of fracture at Th5 or lower; bone oedema on MRI), with back pain for 6 weeks or less, and a visual analogue scale (VAS) score of 5 or more. Patients were randomly allocated to percutaneous vertebroplasty or conservative treatment by computer-generated randomisation codes with a block size of six. Masking was not possible for participants, physicians, and outcome assessors. The primary outcome was pain relief at 1 month and 1 year as measured by VAS score. Analysis was by intention to treat. This study is registered at ClinicalTrials.gov, number NCT00232466. Between Oct 1, 2005, and June 30, 2008, we identified 431 patients who were eligible for randomisation. 229 (53%) patients had spontaneous pain relief during assessment, and 202 patients with persistent pain were randomly allocated to treatment (101 vertebroplasty, 101 conservative treatment). Vertebroplasty resulted in greater pain relief than did conservative treatment; difference in mean VAS score between baseline and 1 month was −5·2 (95% CI −5·88 to −4·72) after vertebroplasty and −2·7 (−3·22 to −1·98) after conservative treatment, and between baseline and 1 year was −5·7 (−6·22 to −4·98) after vertebroplasty and −3·7 (−4·35 to −3·05) after conservative treatment. The difference between groups in reduction of mean VAS score from baseline was 2·6 (95% CI 1·74–3·37, p<0·0001) at 1 month and 2·0 (1·13–2·80, p<0·0001) at 1 year. No serious complications or adverse events were reported. In a subgroup of patients with acute osteoporotic vertebral compression fractures and persistent pain, percutaneous vertebroplasty is effective and safe. Pain relief after vertebroplasty is immediate, is sustained for at least a year, and is significantly greater than that achieved with conservative treatment, at an acceptable cost.

Background One in three women and one in five men over the age of 50 will experience an osteoporotic fracture. Vertebral fractures can be very painful, affect patients’ daily function, and in severe cases require hospitalization. Traditionally, fracture pain is treated conservatively with analgesics, and bracing. Vertebral augmentation, also known as vertebroplasty, has been used during the last three decades as a minimally invasive treatment option for vertebral compression fractures, but the evidence base for its efficacy is weak. We describe a double-blind randomized sham-controlled clinical trial to assess the impact of vertebroplasty on self-reported clinical outcomes in patients with painful osteoporotic vertebral compression fractures and vertebral oedema. Methods Two hundred and forty patients with painful osteoporotic vertebral fractures and MRI verified oedema will be randomized in a prospective, double-blind, single-center, clinical trial to either vertebroplasty or a sham procedure, with the possibility of crossover 12 weeks after randomization and operation. The primary outcome will be difference in self-reported pain 12 weeks after treatment between the vertebroplasty and sham group. Secondary outcomes will be patient-reported disability, health-related quality of life, societal costs of treatment and complications. Analysis will be based on intention-to-treat. Repeated measures ANCOVA with baseline ODI, Numerical Pain Rating Scale, EQ-5D-5 L, and number of levels involved as co-variates will be performed. Discussion With an aging population, the prevalence of osteoporosis and related complications such as vertebral compression fractures is expected to increase. Therefore, there is a growing need for evidence-based fracture treatments. This study fills a gap in the evidence base for treatment of painful osteoporotic vertebral fractures and will likely influence future treatment guidelines. Trial registration The study has been evaluated and approved by the Regional Committees on Health Research for Southern Denmark October 9 2023 (Projekt-ID S-20230058) and the Danish Data Protection Agency 23/40,938. The protocol has been registered at ClinicalTrials.gov with trial registration number NCT06141187 November 21, 2023.

SummaryIn this randomized, controlled trial, treatment with once-weekly subcutaneous injection of teriparatide for 72 weeks was found to be associated with a significant reduction in the incidence of morphometric vertebral fractures compared with alendronate in women with primary osteoporosis who were at high risk of fracture.IntroductionTo determine whether the anti-fracture efficacy of teriparatide is superior to that of alendronate, a prospective, randomized, open-label, blinded-endpoint trial was performed.MethodsJapanese women aged at least 75 years were eligible for the study if they had primary osteoporosis and were at high risk of fracture. Patients were randomly assigned in a 1:1 ratio to receive sequential therapy (once-weekly subcutaneous injection of teriparatide 56.5 μg for 72 weeks followed by alendronate for 48 weeks) or monotherapy with alendronate for 120 weeks. The primary endpoint was the incidence of morphometric vertebral fractures at 72 weeks (at the end of teriparatide treatment).ResultsBetween October 2014 and December 2017, 1011 patients (505 in the teriparatide group and 506 in the alendronate group) were enrolled. Of these, 778 patients (351 and 427, respectively) were included in the primary analysis. The incidence of morphometric vertebral fractures was significantly lower in the teriparatide group (56 per 419.9 person-years, annual incidence rate 0.1334) than in the alendronate group (96 per 553.6 person-years, annual incidence rate 0.1734), with a rate ratio of 0.78 (95% confidence interval 0.61 to 0.99, P = 0.04). In both groups, adverse events were most frequently reported in the following system organ classes: infections and infestations, gastrointestinal disorders, and musculoskeletal and connective tissue disorders.ConclusionOnce-weekly subcutaneous injection of teriparatide significantly reduced the incidence of morphometric vertebral fractures compared with alendronate in women with primary osteoporosis who were at high risk of fracture.Trial registrationjRCTs031180235 and UMIN000015573, March 12, 2019

In this randomized trial involving patients with osteoporotic vertebral compression fractures, patients who underwent vertebroplasty had improvements in pain and disability measures that were similar to those in patients who underwent a sham procedure. Patients who underwent vertebroplasty had improvements in pain and disability measures that were similar to those in patients who underwent a sham procedure. Spontaneous vertebral fractures are associated with pain, disability, and death in patients with osteoporosis. Percutaneous vertebroplasty, the injection of medical cement, or polymethylmethacrylate (PMMA), into the fractured vertebral body has gained widespread acceptance as an effective method of pain relief and has become routine therapy for osteoporotic vertebral fractures. Guidelines recommend vertebroplasty for fractures that have not responded to medical treatment. 1 Typically, the duration of such fractures ranges from several weeks to several months or longer for fractures that have not healed. Numerous case series and several small, unblinded, nonrandomized, controlled studies have suggested the effectiveness of vertebroplasty in relieving . . .

Abstract Context The ACTIVE study demonstrated the antifracture efficacy of abaloparatide in postmenopausal women with osteoporosis. ACTIVExtend demonstrated sustained fracture risk reduction with alendronate in abaloparatide-treated participants from ACTIVE. A direct comparison of the efficacy of abaloparatide and antiresorptive therapies has not been performed. Objective The objective of this analysis is to compare the antifracture efficacy of abaloparatide in ACTIVE with that of alendronate in ACTIVExtend. Design In this post hoc analysis, the rate of new vertebral fractures for women in ACTIVExtend (N = 1139) was calculated based on baseline and endpoint radiographs for placebo or abaloparatide in ACTIVE and alendronate in ACTIVExtend. Vertebral fracture rates between abaloparatide and alendronate were compared in a Poisson regression model. Fracture rates for nonvertebral and clinical fractures were compared based on a Poisson model during 18 months of abaloparatide or placebo treatment in ACTIVE and 18 months of alendronate treatment in ACTIVExtend. Results The vertebral fracture rate was lower during abaloparatide treatment in ACTIVE (0.47 fractures/100 patient-years) than alendronate treatment in ACTIVExtend (1.66 fractures/100 patient-years) (relative risk reduction 71%; P = .027). Although the comparisons did not meet statistical significance, after switching from placebo (ACTIVE) to alendronate (ACTIVExtend), the rate of new vertebral fractures decreased from 2.49 to 1.66 fractures per 100 patient-years, and after switching from abaloparatide to alendronate from 0.47 to 0.19 fractures per 100 patient-years. The rates of nonvertebral fractures and clinical fractures were not significantly different. Conclusion Initial treatment with abaloparatide may result in greater vertebral fracture reduction compared with alendronate in postmenopausal women with osteoporosis.

Abstract BACKGROUND Osteoporotic and neoplastic vertebral compression fractures (VCF) are common and painful, threatening quality of life and increasing risk of morbidity and mortality. Balloon kyphoplasty is a percutaneous option for treating painful cancer- and osteoporosis-related VCFs, supported by 2 randomized trials demonstrating efficacy benefits of BKP over nonsurgical care. OBJECTIVE To investigate 12-mo disability, quality of life, and safety outcomes specifically in a Medicare-eligible population, representing characteristic patients seen in routine clinical practice. METHODS A total of 354 patients with painful VCFs were enrolled at 24 US sites with 350 undergoing kyphoplasty. Four coprimary endpoints—Numerical Rating Scale (NRS) back pain, Oswestry Disability Index (ODI), Short Form-36 Questionnaire Physical Component Summary (SF-36v2 PCS), EuroQol-5-Domain (EQ-5D)—were evaluated for statistically significant improvement 3 mo after kyphoplasty. Data were collected at baseline, 7 d, and 1, 3, 6, and 12 mo (www.clinicaltrials.gov registration NCT01871519). RESULTS At the 3-mo primary endpoint, NRS improved from 8.7 to 2.7 and ODI improved from 63.4 to 27.1; SF-36 PCS was 24.2 at baseline improving to 36.6, and EQ-5D improved from 0.383 to 0.746 (P < .001 for each). These outcomes were statistically significant at every follow-up time point. Five device-/procedure-related adverse events, intraoperative asymptomatic balloon rupture, rib pain, and aspiration pneumonia, and a new VCF 25 d postprocedure, and myocardial infarction 105 d postprocedure were reported and each resolved with proper treatment. CONCLUSION This large, prospective, clinical study demonstrates that kyphoplasty is a safe, effective, and durable procedure for treating patients with painful VCF due to osteoporosis or cancer.

Background Percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) are widely used in the treatment of Kümmell’s disease. The purpose of this article is to investigate the clinical efficacy of PVP and PKP for Kümmell’s disease. Methods The clinical data that 56 cases of Kümmell’s disease treated with either PVP (28 cases) or PKP (28 cases) from December 2015 to December 2017 were prospectively analyzed. Gender, age, course of disease, injury segment, bone mineral density (BMD), visual analogue scale (VAS), Oswestry disability index (ODI), imaging measurement indexes before surgery between the two groups showed no significant difference (all P  > 0.05). The bone cement leakage rate, bone cement injection amount, operation time, VAS, ODI, the rate of vertebral compression, correction rate of kyphosis and refracture rate of adjacent vertebra in 2 years were compared between the two groups to calculate clinical efficacy. Results The two groups were followed up for 24–48 months. There was no significant difference in the follow-up time, amount of bone cement injected, incidence of bone cement leakage and refracture rate of adjacent vertebrae between the two groups (all P  > 0.05). The operation time, intraoperative blood loss and fluoroscopy times of the PVP group were significantly lower than those of the PKP group (all P  = 0.000). VAS score and ODI of the two groups were significantly lower at 1 day, 1 year and 2 years after surgery than before surgery (all P  < 0.05), but there was not statistically significant difference between the two groups at each time point after surgery (all P  > 0.05). The rate of vertebral compression and kyphosis correction in the two groups were significantly corrected ( P  < 0.05, respectively) and decreased significantly with time (all P  < 0.05), But there was not significant difference between the two groups at any time point (all P  > 0.05). Conclusion Both PVP and PKP can achieve similar effects in the treatment of Kümmell’s disease. Because the cost, operation time, blood loss, radiation exposure and surgical procedure of PVP are less than those of PKP, PVP has more clinical priority value.
