Physiotherapy exercise rehabilitation with tailored exercise adherence support for people with osteoporosis and vertebral fractures: protocol for a randomised controlled trial - the OsteoPorosis Tailored exercise adherence INtervention (OPTIN) study. BMJ open INTRODUCTION:Vertebral fragility fractures affect at least 20% of the older population in the UK. Best practice guidelines recommend the use of exercise to slow the rate of bone loss, to maintain muscle strength and physical function, and to prevent falls and further fractures. However, treatment effects are often small and difficult to sustain and adherence, or the extent to which patients engage in treatment, has been identified as an important issue by many studies. Our hypothesis is that integrating adherence intervention strategies with an exercise intervention will be beneficial. We will compare physiotherapy exercise rehabilitation with adherence support versus physiotherapy exercise rehabilitation alone in terms of effects on (A) physical function, quality of life and fear of falling and (B) exercise self-efficacy and adherence. METHODS AND ANALYSIS:A multicentre, two-arm, parallel group, superiority randomised controlled trial with blinded assessments at baseline (0) and 4, 8 and 12 months, with a nested qualitative study and health economic analysis. 116 participants will be allocated to either (1) outpatient physiotherapy which will include a musculoskeletal assessment and treatment including balance, posture, strength training and low impact weight-bearing exercises over 16 weeks or (2) OsteoPorosis Tailored exercise adherence INtervention intervention. This includes standard physiotherapy as above plus an additional, integrated assessment interview (30 min) and 60 min of adherence support spread over the subsequent 16 weeks. ETHICS AND DISSEMINATION:The study protocol was approved by West of Scotland Research Ethics Committee 4 (21/WS/0071). Trial registration number ISRCTN 14465704. The paper is based on Protocol V.4. TRIAL REGISTRATION NUMBER:ISRCTN 14465704. 10.1136/bmjopen-2022-064637
Risk factors for vertebral fractures and bone loss after denosumab discontinuation: A real-world observational study. Everts-Graber J,Reichenbach S,Gahl B,Ziswiler H R,Studer U,Lehmann T Bone BACKGROUND:Denosumab discontinuation without subsequent bisphosphonates (BPs) is associated with bone loss and multiple vertebral fractures. OBJECTIVE:Identifying risk factors for bone loss and vertebral fractures after denosumab discontinuation. METHODS:This retrospective study measured the outcome of 219 women with osteoporosis who discontinued denosumab treatment and received subsequent treatment with zoledronate, other BPs or a selective estrogen receptor modulator (SERM), or no therapy. Fracture rate, longitudinal bone mineral density (BMD) changes and bone turnover markers (BTMs) within 2 years after denosumab discontinuation were analysed. Linear regression analysis evaluated loss of BMD and age, BMI (kg/m), denosumab treatment duration, pre-treatment, prior fracture state, baseline T-scores, use of glucocorticoids or aromatase inhibitors and BMD gains under denosumab therapy. RESULTS:171 women received zoledronate after denosumab discontinuation, 26 had no subsequent treatment and 22 received other therapies (other BPs or a SERM). Zoledronate was associated with the fewest vertebral fractures (hazard ratio 0.16, p = 0.02) and all subsequent therapies retained BMD at all sites to some extent. Higher BMD loss was associated with younger age, lower BMI, longer denosumab treatment, lack of prior antiresorptive treatment and BMD gain under denosumab treatment. BTM levels correlated with denosumab treatment duration and bone loss at the total hip, but not the lumbar spine. CONCLUSIONS:Compared to no subsequent therapy, zoledronate was associated with fewer vertebral fractures after denosumab. Further, BMD loss depended on denosumab treatment duration, age, prior BP therapy and BMD gain under denosumab therapy, whereas BTM levels were associated with bone loss at the total hip and denosumab treatment duration. 10.1016/j.bone.2020.115830
Prediction of Subsequent Vertebral Fracture After Acute Osteoporotic Fractures from Clinical and Paraspinal Muscle Features. Calcified tissue international To construct a nomogram based on clinical factors and paraspinal muscle features to predict vertebral fractures occurring after acute osteoporotic vertebral compression fracture (OVCF). We retrospectively enrolled 307 patients with acute OVCF between January 2013 and August 2022, and performed magnetic resonance imaging of the L3/4 and L4/5 intervertebral discs (IVDs) to estimate the cross-sectional area (CSA) and degree of fatty infiltration (FI) of the paraspinal muscles. We also collected clinical and radiographic data. We used univariable and multivariable Cox proportional hazards models to identify factors that should be included in the predictive nomogram. Post-OVCF vertebral fracture occurred within 3, 12, and 24 months in 33, 69, and 98 out of the 307 patients (10.8%, 22.5%, and 31.9%, respectively). Multivariate analysis revealed that this event was associated with percutaneous vertebroplasty treatment, higher FI at the L3/4 IVD levels of the psoas muscle, and lower relative CSA of functional muscle at the L4/5 IVD levels of the multifidus muscle. Area under the curve values for subsequent vertebral fracture at 3, 12, and 24 months were 0.711, 0.724, and 0.737, respectively, indicating remarkable accuracy of the nomogram. We developed a model for predicting post-OVCF vertebral fracture from diagnostic information about prescribed treatment, FI at the L3/4 IVD levels of the psoas muscle, and relative CSA of functional muscle at the L4/5 IVD levels of the multifidus muscle. This model could facilitate personalized predictions and preventive strategies. 10.1007/s00223-024-01209-0
Osteoporotic fractures and subsequent fractures: imminent fracture risk from an analysis of German real-world claims data. Hadji Peyman,Schweikert Bernd,Kloppmann Edda,Gille Patrick,Joeres Lars,Toth Emese,Möckel Luis,Glüer Claus-C Archives of gynecology and obstetrics PURPOSE:In osteoporosis, prior fracture is a strong predictor of subsequent fracture. This study aimed to assess the imminent risk of subsequent fracture following an initial fracture in osteoporosis patients in Germany, and to identify clinical and demographic characteristics that are independently associated with subsequent fracture risk. METHODS:In this retrospective, observational cohort study using German real-world claims data, male and female patients aged ≥ 50 years with osteoporosis who experienced an initial ("index") hip/femur, vertebral, forearm/wrist/hand or shoulder/upper arm fracture between 2010 and 2014 were included. The incidence and timing of subsequent fractures during a 1-year follow-up period were analyzed. Independent risk factors for subsequent fracture were identified by multivariate regression analysis. RESULTS:A total of 18,354 patients (mean age: 77 years; standard deviation: 9.8) were included. Of these, 2918 (15.9%) suffered a subsequent fracture during the 1-year follow-up period. The incidence of subsequent fracture was higher following an index vertebral fracture (18.0%) than after an index forearm/wrist/hand fracture (14.1%) or index hip/femur fracture (12.1%). Subsequent 1-year fracture incidence was generally higher in older patients. Index fracture type, age, epilepsy/use of antiepileptics, and heart failure were all independently associated with subsequent fracture risk. CONCLUSION:Osteoporosis patients in Germany are at imminent risk of subsequent fracture during the first year following an initial fracture. They should be targeted for immediate post-fracture treatment to reduce the risk of further fractures, especially in the presence of specific risk factors such as old age or index vertebral fracture. 10.1007/s00404-021-06123-6
Comparing three machine learning approaches to design a risk assessment tool for future fractures: predicting a subsequent major osteoporotic fracture in fracture patients with osteopenia and osteoporosis. de Vries B C S,Hegeman J H,Nijmeijer W,Geerdink J,Seifert C,Groothuis-Oudshoorn C G M Osteoporosis international : a journal established as result of cooperation between the European Foundation for Osteoporosis and the National Osteoporosis Foundation of the USA Four machine learning models were developed and compared to predict the risk of a future major osteoporotic fracture (MOF), defined as hip, wrist, spine and humerus fractures, in patients with a prior fracture. We developed a user-friendly tool for risk calculation of subsequent MOF in osteopenia patients, using the best performing model. INTRODUCTION:Major osteoporotic fractures (MOFs), defined as hip, wrist, spine and humerus fractures, can have serious consequences regarding morbidity and mortality. Machine learning provides new opportunities for fracture prediction and may aid in targeting preventive interventions to patients at risk of MOF. The primary objective is to develop and compare several models, capable of predicting the risk of MOF as a function of time in patients seen at the fracture and osteoporosis outpatient clinic (FO-clinic) after sustaining a fracture. METHODS:Patients aged > 50 years visiting an FO-clinic were included in this retrospective study. We compared discriminative ability (concordance index) for predicting the risk on MOF with a Cox regression, random survival forests (RSF) and an artificial neural network (ANN)-DeepSurv model. Missing data was imputed using multiple imputations by chained equations (MICE) or RSF's imputation function. Analyses were performed for the total cohort and a subset of osteopenia patients without vertebral fracture. RESULTS:A total of 7578 patients were included, 805 (11%) patients sustained a subsequent MOF. The highest concordance-index in the total dataset was 0.697 (0.664-0.730) for Cox regression; no significant difference was determined between the models. In the osteopenia subset, Cox regression outperformed RSF (p = 0.043 and p = 0.023) and ANN-DeepSurv (p = 0.043) with a c-index of 0.625 (0.562-0.689). Cox regression was used to develop a MOF risk calculator on this subset. CONCLUSION:We show that predicting the risk of MOF in patients who already sustained a fracture can be done with adequate discriminative performance. We developed a user-friendly tool for risk calculation of subsequent MOF in patients with osteopenia. 10.1007/s00198-020-05735-z
Association between handgrip strength and subsequent vertebral-fracture risk following percutaneous vertebral augmentation. Zhang Shu-Bao,Chen Hao,Xu Hao-Wei,Yi Yu-Yang,Wang Shan-Jin,Wu De-Sheng Journal of bone and mineral metabolism INTRODUCTION:The aim of this study was to investigate the association between handgrip strength (HGS) and the risk of subsequent vertebral fracture (SVF) after percutaneous vertebral augmentation (PVA). MATERIALS AND METHODS:A total of 340 patients aged over 50 years with osteoporotic vertebral fracture were enrolled in this 3-year follow-up investigation. HGS was measured with a hand-held dynamometer before PVA. Female patients and male patients were grouped using the HGS threshold recommended by the Asian Working Group for Sarcopenia (AWGS). Kaplan-Meier analysis was used to evaluate SVF-free survival. The hazard ratios (HRs) of HGS for SVF events were estimated with the Cox proportional hazards model. RESULTS:During the follow-up period, a total of 93 patients (27.4%) experienced SVF. Kaplan-Meier analysis showed that the HGS of female patients < 18.0 kg and male patients < 28 kg was significantly associated with lower SVF-free survival (female patients: p < 0.001, male patients: p = 0.038; log-rank test). Among women, each 1-kg increase in HGS was associated with a 9% lower risk of SVF (HR 0.91, p = 0.035) after adjustment for potential risk factors. Among men, although the associations between low HGS and increased risk of SVF were significant in the crude model (HR 0.79, p < 0.001), this significance disappeared after adjustment for bone mineral density of the femoral neck. CONCLUSIONS:Low HGS was significantly associated with lower SVF-free survival among elderly patients who underwent single-level PVA for osteoporotic vertebral fracture. 10.1007/s00774-020-01131-z
Association Between Abdominal Obesity and Subsequent Vertebral Fracture Risk. Pain physician BACKGROUND:Obesity had been previously considered to be a protective factor against osteoporosis or fractures; however, recent research indicates that obesity, especially abdominal obesity, may increase the risk of some types of fractures. OBJECTIVE:We explored the effects of abdominal obesity on subsequent vertebral fracture (SVF) after percutaneous vertebral augmentation (PVA). STUDY DESIGN:A prospective observational cohort study. SETTING:Department of Spinal Surgery of a hospital affiliated with a medical university. METHODS:A total of 390 women and 237 men aged > 50 years suffering from osteoporotic vertebral fracture (OVF) were included. Weight, height, bone mineral density (BMD), abdominal circumference, and other basic information were measured at baseline and 1-year follow-up visit. RESULTS:During follow-up, 80 (33.7%) men and 143 (36.7%) women incurred SVF. Greater waist circumference (WC) and waist-to-hip ratio (WHR) increased the risk of SVF in men (WC: HR 1.83, P = 0.016; WHR: HR 1.63, P = 0.045) and women (WC: HR 2.75, P = 0.001; WHR: HR 2.63, P = 0.001) after adjustment for BMD and other potential confounders. Compared with normal BMI, being overweight was associated with lower SVF risk (women: HR 0.55, P = 0.044; men: HR 0.46, P = 0.046), and obesity was associated with greater SVF risk (women: HR 4.53, P < 0.001; men: HR 3.77, P < 0.001) in both genders. We observed a nonlinear relationship between BMI and SVF with a U-shaped curve; after adjusting BMD, this became a reverse J-curve. LIMITATIONS:There was no further statistical analysis of the relationship between abdominal obesity and other fracture sites. Asymptomatic SVF may underestimate the impact of abdominal obesity on the occurrence of SVF. CONCLUSIONS:Abdominal obesity was significantly associated with a higher risk of SVF after PVA. Management of body type after PVA may be an effective prevention strategy against SVF.
Correlation Analysis Between Basic Diseases and Subsequent Vertebral Fractures After Percutaneous Kyphoplasty (PKP) for Osteoporotic Vertebral Compression Fractures. Ning Lei,Zhu Jungao,Tian Shen,Hu Ziang,Liu Chao,Zhao Xiangde,Li Xiang,Fan Shunwu,Wan Shuanglin Pain physician BACKGROUND:Percutaneous kyphoplasty (PKP) is a widely accepted surgical treatment modality for painful osteoporotic vertebral compression fractures. The risk factors cause of subsequent vertebral fractures after PKP are debated. OBJECTIVES:To evaluate risk factors for the occurrence of new vertebral compression fractures after PKP. STUDY DESIGN:A retrospective study. SETTING:A single-center inpatient population. METHODS:A total of 921 patients (1,152 vertebrae) with PKP were investigated. Among those patients, 111 patients (155 levels) incurred refractures after PKP. RESULTS:The average bone mineral density was -3.27 in the "refracture"group and -3.00 in the "no fracture" group (P = 0.031). Morbidities of women were significantly higher in the "refracture" group (90.99%) compared with the "no fracture" group (81.73%) (P = 0.015). Among the basic diseases, several diseases (history of previously fracture, previously osteoporosis, gallstone disease, stomach disease, and ovariectomy) are associated with refractures after PKP (P < 0.05). And antiosteoporotic treatment (calcium + vitamin D or zoledronate) after PKP can also significantly reduce the occurrence of refracture (P < 0.000). In addition, logistic regression analysis also showed that most of the above contents had significant correlation with the refracture after PKP (P < 0.05), except for gallstone disease (P = 0.362). LIMITATIONS:Retrospective study, single center. CONCLUSION:Osteoporosis is the main cause of refracture after PKP. Elderly women were found to be more susceptible than elderly men to refracture. Patients with a history of previously fracture, previously osteoporosis, stomach ulcer, and ovariectomy are more likely to be refracture. Antiosteoporosis treatment (calcium + vitamin D or zoledronate) after PKP can reduce the risk of refracture.
Real-world effectiveness of anti-osteoporosis medications for the prevention of incident hip and clinical vertebral fractures in patients on long-term glucocorticoid therapy: A nationwide health insurance claims database study in Japan. Bone PURPOSE:Early initiation of anti-osteoporosis medications (AOMs) is recommended for patients on long-term glucocorticoid (GC) therapy. This study aimed to clarify the real-world effectiveness of AOMs against incident hip and vertebral fractures in patients undergoing GC therapy using the nationwide health insurance claims database of Japan (NDBJ). METHODS:Patients aged ≥50 years who were prescribed GC (≥5 mg/day prednisolone or equivalent) for ≥90 days and who were followed up regarding AOM prescription and hip and clinical vertebral fracture incidences for the subsequent 1080 days between 2012 and 2018 were selected from NDBJ. Associations of AOMs prescribed within 90 days since GC therapy initiation with hip or vertebral fracture risk were evaluated by Cox proportional hazards regression using propensity score inverse probability weighting (IPW) for receiving any AOM or individual AOMs. RESULTS:In total, 96,475 women and 98,385 men were included in the analysis; 38.0 % of women and 27.6 % of men received AOMs. Patients who received any AOM and those who received bisphosphonates or denosumab had a significantly lower risk of hip and clinical vertebral fractures than those who received no AOM in both sexes after propensity score IPW. Teriparatide was associated with an increased risk of both fractures in women and an increased risk of clinical vertebral fractures in men. Selection biases such as confounding by indication might have caused an underestimation of AOMs' protective effects. CONCLUSIONS:Bisphosphonates and denosumab were associated with a lower fracture incidence in patients on long-term GC therapy in real-world settings. 10.1016/j.bone.2022.116605
Subsequent fractures after vertebroplasty in osteoporotic vertebral fractures: a meta-analysis. Neurosurgical review Percutaneous vertebroplasty (VP) provides substantial benefit to patients with painful osteoporotic vertebral compression fractures (OVCF). However, the reoccurrence of vertebral fracture after VP is a major concern. The purpose of this study is to conduct a meta-analysis on the incidence of subsequent fractures after VP in patients with OVCF. PubMed and EMBASE were searched. In addition, we scrutinized the reference list of all relevant articles to supplement the database search. We included original articles reporting on new fracture rates after VP in OVCF patients. Subsequent fracture rates were pooled across studies using a random-effects meta-analysis. Thirty-nine studies with a total of 8047 participants from 12 countries were included in this meta-analysis. Patients' age ranged from 64.2 to 94.6 years (reported by 31 studies). The median follow-up was 21 months (36 studies). Pooled estimate for subsequent fractures after VP was 23.4% (95% CI, 19.8-27.2%; I = 93.0%, p < 0.01). New fractures after VP in 54.6% of cases occurred in the vertebral bodies adjacent to the treated vertebra (95% CI, 49.0-60.1%; I = 66.0%, p < 0.01). A significant proportion of patients undergoing VP for OVCF experience new fractures after treatment, most of which are developed in the vertebral bodies adjacent to the treated vertebra. 10.1007/s10143-022-01755-x
Vertebral fractures cascade: potential causes and risk factors. Che H,Breuil V,Cortet B,Paccou J,Thomas T,Chapuis L,Debiais F,Mehsen-Cetre N,Javier R M,Loiseau Peres S,Roux C,Briot K Osteoporosis international : a journal established as result of cooperation between the European Foundation for Osteoporosis and the National Osteoporosis Foundation of the USA We performed a study to identify potential causes and risk factors of vertebral fracture cascade. Vertebral fracture cascade is a severe clinical event in patients with bone fragility. Only half of patients have an identified cause of secondary osteoporosis. INTRODUCTION:Vertebral fracture (VF) is the most common osteoporotic fracture, and a strong risk factor of subsequent VFs leading to VF cascade (VFC). We prompted a study to identify potential causes and risk factors of VFC. METHODS:VFC observations were collected retrospectively between January 2016 and April 2017. VFC was defined as an occurrence of at least three VFs within 1 year. RESULTS:We included in 10 centers a total of 113 patients with VFC (79.6% of women, median age 73, median number of VFs in the cascade, 5). We observed 40.5% and 30.9% of patients with previous major fractures and a previous VF, respectively, and 68.6% with densitometric osteoporosis; 18.9% of patients were currently receiving oral glucocorticoids and 37.1% in the past. VFC was attributed by the physician to postmenopausal osteoporosis in 54% of patients. A secondary osteoporosis associated with the VFC was diagnosed in 52 patients: glucocorticoid-induced osteoporosis (25.7%), non-malignant hemopathies (6.2%), alcoholism (4.4%), use of aromatase inhibitors (3.6%), primary hyperparathyroidism (2.7%), hypercorticism (2.7%), anorexia nervosa (2.7%), and pregnancy and lactation-associated osteoporosis (1.8%). A total of 11.8% of cases were reported following a vertebroplasty procedure. A total of 31.5% patients previously received an anti-osteoporotic treatment. In six patients, VFC occurred early after discontinuation of an anti-osteoporotic treatment, in the year after the last dose effect was depleted: five after denosumab and one after odanacatib. CONCLUSION:The results of this retrospective study showed that only half of VFC occurred in patients with a secondary cause of osteoporosis. Prospective studies are needed to further explore the determinants of this severe complication of osteoporosis. 10.1007/s00198-018-4793-1
Incidence and mortality of subsequent vertebral fractures: analysis of claims data of the Korea National Health Insurance Service from 2007 to 2016. Park Sang-Min,Ahn Seong Hee,Kim Ha-Young,Jang Sunmee,Ha Young-Chan,Lee Young-Kyun,Chung Ho-Yeon The spine journal : official journal of the North American Spine Society BACKGROUND CONTEXT:Vertebral fracture is related to an increased risk for subsequent and recurrent osteoporotic fracture as well as increased mortality. However, no study has investigated the exact incidence and mortality of subsequent vertebral fractures. OBJECTIVE:The purpose of our study was to determine trends in the incidence and mortality of subsequent vertebral fractures after first-time vertebral fracture in Koreans older than 50 years using the national claims database. STUDY DESIGN:Retrospective cohort study. PATIENT SAMPLE:Data from the Korea National Health Insurance Service database from 2007 to 2016. OUTCOME MEASURES:The incidence of subsequent vertebral fracture during a 4-year follow-up period. The mortality and standardized mortality ratio (SMR) after subsequent vertebral fractures during the 1-year period after fracture were also determined. Analysis was restricted to patients older than 50 years. METHODS:The national claims data set was analyzed to find all new visits and revisits after 6 months from the last claim to a hospital or clinic for vertebral fractures and revisits in men and women aged 50 years or older between 2007 and 2016. The number of first-time vertebral fractures in 2012 was investigated to determine subsequent vertebral fractures. The incidence, mortality rates, and SMR of subsequent vertebral fractures were calculated. There were no sources of funding and no conflicts of interest associated with this study. RESULTS:During the 4-year follow-up period, the overall cumulative incidence of subsequent vertebral fractures were 27.53%. According to sex, the cumulative incidence of subsequent vertebral fractures was 20.09% in men and 29.98% in women. The cumulative mortality rate over the first year after subsequent vertebral fractures was 5%. The mortality rates over 1 year were 10.04% for men and 3.81% for women. The overall SMR at the 1-year follow-up after subsequent vertebral fractures was 10.58 (95% confidence interval: 9.29-12.05) in men and 3.88 (95% confidence interval: 3.5-4.3) in women. CONCLUSIONS:Our study showed that subsequent vertebral fractures were more common in women, with an incidence rate of 29.98% over 4 years. However, the mortality rate was higher in men, reaching 10.04% in 1 year. Subsequent vertebral fractures occurred in large numbers, and the mortality rates were relatively high. Thus, first vertebral fracture may be considered as an early warning of high risk for future subsequent vertebral fractures, especially in women. 10.1016/j.spinee.2019.09.025
Use of Parathyroid Hormone and Rehabilitation Reduces Subsequent Vertebral Body Fractures after Balloon Kyphoplasty. Asian spine journal STUDY DESIGN:Retrospective cohort study. PURPOSE:To evaluate the efficacy of our current prophylactic strategy by investigating the incidence of subsequent vertebral body fractures (SVBFs) following balloon kyphoplasty (BKP). OVERVIEW OF LITERATURE:Although extensive studies have investigated the risk factors for SVBFs after BKP, few have reported on postoperative therapies to prevent SVBFs and have evaluated their effectiveness. METHODS:This study enrolled 273 patients who underwent an initial BKP. To treat osteoporosis, parathyroid hormone (PTH) administration was started 1-2 weeks before BKP and continued for at least 6 months postoperatively. Corsets were applied for 3 months after the procedure. Rehabilitative interventions, including hip range-of-motion training, muscle strengthening exercises, and motion/posture instruction, were started from the preoperative assessment time point and resumed 3 hours postoperatively. Corsets were used in all patients. Therefore, no grouping based on corset use was performed. PTH was used in 180 patients, and they were divided into the following two groups: PTH user group and PTH nonuser group. Rehabilitative interventions were provided to all patients for a median duration of 17 days. Patients who underwent rehabilitative intervention for <17 and ≥17 days were included in the short-term and long-term intervention groups, respectively. The incidences of SVBFs for these four groups were compared. RESULTS:SVBF occurred in 29 patients (10.6%). The SVBF incidence among patients who were prescribed all three prophylactic measures was 6.2%. The PTH user group had a significantly lower incidence of distant vertebral body fractures as compared to the PTH nonuser group. The long-term rehabilitation group had a significantly lower incidence of SVBFs and adjacent vertebral body fractures within 50 postoperative days than the short-term group. CONCLUSIONS:A 17-day or longer rehabilitative intervention may lower the risk of early adjacent vertebral body fractures, and the use of PTH may reduce the risk of distant vertebral body fractures. 10.31616/asj.2020.0608
Comparative analysis of anti-osteoporosis medications in preventing vertebral body fractures after balloon kyphoplasty. Archives of osteoporosis This retrospective study compared the efficacy of anabolic agents (romosozumab and teriparatide) with that of alendronate in preventing subsequent vertebral body fractures (SVBFs) after balloon kyphoplasty (BKP). All anabolic agents significantly reduced SVBFs. Romosozumab was most effective in increasing bone mineral density (BMD) and completely suppressed distant vertebral body fractures. INTRODUCTION:To determine optimal anti-osteoporosis medications, we compared romosozumab and teriparatide to alendronate as a control from perioperative BKP to the 1st postoperative year for treatment and secondary fracture prevention in osteoporosis. METHODS:A total of 603 patients who underwent initial BKP for osteoporotic vertebral fractures were evaluated and categorized into five groups based on drug administration: romosozumab (group R, 155 patients), twice-weekly teriparatide (group TW, 48), weekly teriparatide (group W, 151), daily teriparatide (group D, 138), and alendronate (control) (group C, 111). The 1-year incidence of SVBFs, BMD change rate, and probability of requiring BKP were compared among the groups. RESULTS:SVBF incidence was 3.9%, 6.5%, 8.3%, 6.0%, and 14.4% in groups R, D, TW, W, and C, respectively, with all other groups exhibiting significantly lower rates than group C. The groups that administered the anabolic agents had a notably lower incidence of distant fractures than group C. Compared with group C, group R showed significantly higher BMD change rates in lumbar vertebral bodies at 4, 8, and 12 months and group D at 12 months. Anabolic agent groups exhibited significantly higher improvement rates than group C after conservative treatment alone. CONCLUSION:The anabolic agents were found to be more effective at reducing the incidence of SVBF (especially distant vertebral fractures) than alendronate. These agents decreased the rate of repeat BKP even after the occurrence of a fracture. Overall, the use of an anabolic agent for the treatment of osteoporosis after BKP is better than the use of alendronate, even when treatment is initiated in the perioperative stage. 10.1007/s11657-024-01374-7
