Spinal Orthoses for Vertebral Osteoporosis and Osteoporotic Vertebral Fracture: A Systematic Review

Regional disparities in the risk of secondary fractures in patients with hip fractures

PURPOSE

We aimed to examine the regional disparities in secondary fracture incidence among patients with hip fractures in South Korea.

METHODS

This observational, retrospective, cohort study was conducted using data of 6,213 South Korean nationals from the National Health Insurance Service-National Sample Cohort (2004-2019). Secondary fractures included hip, wrist, humerus, spine, ankle, and pelvis fractures that occurred 6 months after hip fracture. The position value for relative composite index was used to identify medically vulnerable regions. Cox proportional hazards models were used for statistical analysis.

RESULTS

Among the 6,213 (1,949 male, 4,264 female) patients with hip fracture, 981 lived in medically vulnerable areas and 5,232 in non-vulnerable areas. Patients residing in vulnerable areas had a higher risk of secondary fractures than did those residing in non-vulnerable areas (hazard ratio [HR]: 1.24, 95 % confidence interval [CI]: 1.05-1.47); the factors that increased their risk included female sex (HR: 1.30, 95 % CI: 1.08-1.57), age ≥71 years (HR: 1.23, 95 % CI: 1.01-1.44), and not receiving osteoporosis medication (HR: 1.47, 95 % CI: 1.14-1.89). Ten years after hip fracture surgery, the risk of secondary fracture more than tripled in the vulnerable areas than that in the non-vulnerable areas.

CONCLUSION

Patients living in vulnerable regions had a higher risk of secondary fractures than that of those in non-vulnerable regions. Prevention and medication policies should thus be implemented to reduce regional healthcare disparities.

Effect of spinal orthoses on osteoporotic elderly patients kyphosis, back muscles strength, balance and osteoporotic vertebral fractures: (A systematic review and meta-analysis)

In this review and meta-analysis, we aimed to investigate the effect of spine orthotics in osteoporotic patients. The relationship between osteoporosis, osteoporotic vertebral fractures (OVFs), and age-related hyperkyphosis has made this effect unclear. We believe that taking participants' conditions into consideration may help to alleviate this controversy. The electronic database includes Web of Science, PubMed, Cochrane Library, Medline, and ClinicalTrials.gov. For English language literature was searched up to March 2023, and 34 articles were included in the review and 15 article had sufficient quality for meta-analysis based on the methodology quality index. There was no significant effect found from using either rigid or soft orthoses alone during the acute phase of one level (OVFs). Both semi-rigid and weighted orthoses have shown a positive significant effect on thoracic kyphosis angle and back extensor muscle strength in osteoporotic or older hyperkyphotic patients. The results of this review indicate that using a soft or rigid orthosis alone does not have a superior effect in the acute phase of one-level (OVFs) compared to not using an orthosis. However, using a semi-rigid or weighted orthosis in osteoporotic or hyperkyphotic older adults with or without (OVFs) can benefit thoracic kyphosis angle, back muscle strength, and balance.

Dynamic spinal orthoses self-reported effects in patients with back pain due to vertebral fragility fractures: A multi-center prospective cohort study

BACKGROUND

Vertebral fragility fractures (VFFs) commonly result from low bone mass and microarchitecture deterioration of bone tissue. spinal orthoses are common non-pharmacological options for managing vertebral fracture pain. However, the effects of spinal orthoses on pain, physical functioning, and quality of life (QoL) are still debated.

OBJECTIVE

This survey aimed to investigate the patients-reported outcomes of a dynamic spinal orthosis prescribed in the routine clinical practice of VFFs management.

METHODS

This multi-center national-wide prospective cohort study assessed older patients (aged > 60 years) diagnosed with acute VFFs and prescribed with a dynamic spinal orthosis (Spinfast®). A survey questionnaire was realized and included sections on patient characterization, osteoporosis characterization, spinal orthosis, clinical outcomes, pain medications, and osteoporosis medications. The questionnaire was administered at baseline and after three months. A total of 68 patients completed the questionnaire at three months. Most patients had one or two VFFs and were treated with pain medications and osteoporosis medications. Compliance and tolerability of the spinal orthosis were assessed, and clinical outcomes such as pain intensity, physical functioning, and QoL were measured.

RESULTS

The results showed no significant differences in outcomes between age subgroups. Italian physical medicine and rehabilitation physicians were commonly involved in the management of VFFs patients. Sixty-six patients completed the questionnaire. The results showed that pain intensity, physical functioning and QoL improved after three months of spinal orthosis wearing (p< 0.0001).

CONCLUSION

The correct management of VFFs is mandatory to improve pain and reduce disability, and our findings suggested a positive role of dynamic spinal orthosis to improve the comprehensive management of VFFs patients. However, high-quality research trials are warranted to provide clear recommendations for the correct clinical management of VFF.

The Effect of Group Training or Spinal Orthosis on Quality of Life and Potential Plasma Markers of Pain in Older Women With Osteoporosis. A Randomized Controlled Trial

Objective

Primary purpose was to examine the effects of exercise and use of a spinal orthosis on quality of life (QoL). Secondary, to explore the effects of above-mentioned interventions on plasma levels of potential markers of pain: substance P (SP), calcitonin gene-related peptide (CGRP), and interleukin-6 (IL-6).

Design

Randomized controlled trial.

Setting

Community-dwelling women in Stockholm.

Participants

A total of 113 women aged 60-93 years suffering from back pain and self-reported osteoporosis (n=113).

Interventions

The randomized controlled trial was 3-armed: participation in an equipment exercise group, treatment with an activating spinal orthosis or controls. The intervention time was 6 months.

Main Outcome Measures

QoL (QUALEFFO-41 and SF-36), plasma levels of SP, CGRP, and IL-6 measured at baseline and after 6 months in all 3 arms.

Results

No improvement of QoL was found. Comparing change in mobility (QUALEFFO-41), the effect in least squares means was lower in the spinal orthosis group compared with controls. In the exercise group, the role emotional score (SF-36) deteriorated during the intervention. Effect size varied between 0.02 and 0.6. There was no change in the levels of CGRP or SP, while IL-6 levels were lower at 6 months in the spinal orthosis group compared with the other groups. At least 1 previous vertebral fracture was verified by X-ray in 46 women.

Conclusion

The interventions showed none or negative effect on QoL, which was unexpected. The modest effect size may prompt a cautious interpretation. We found a lowering of IL-6 levels in the spinal orthosis group, but more studies are needed.

Thoraco-lumbar-sacral orthoses in older people - A narrative literature review

Fractures in the thoracolumbar region have a bimodal distribution, with an increasing number of older people presenting with acute vertebral fractures after atraumatic or low energy mechanisms of injury. In the absence of neurological compromise and significant vertebral instability, thoracolumbar fractures are often managed conservatively and bracing is widely recommended. However, in older cohorts, bracing is often ill fitting and poorly tolerated with non-compliance leading to prolonged immobilization. Systematic reviews and meta-analyses have challenged the motive of bracing, but as evidence quality is low, the role of exploratory analysis has been limited. This descriptive review summarises and examines the current evidence that underpins the use of spinal orthoses, specific to older patients, in an effort to streamline its judicious use in clinical practice and identify scope to direct further research.

Physiotherapy post Vertebral Fragility Fracture: A Scoping Review

BACKGROUND

The incidence of vertebral fragility fractures (VFF) is rising, placing a major burden on individuals and health systems. No comprehensive picture of the research regarding physiotherapy exists for this patient cohort.

OBJECTIVES

This scoping review aims to summarise the research regarding Physiotherapy post VFF, the type of physiotherapy interventions employed and outcome measures utilised.

DESIGN

Scoping review, adhering to the Joanna Briggs Institute guidelines. Databases searched were PubMed, PEDro, CINAHL, Cochrane, Embase from 2005 to November 2021. Grey literature searching was conducted using ProQuest and Open Grey. A narrative summary of data was compiled to describe the current evidence regarding physiotherapy post VFF.

STUDY SELECTION

Articles were included if they related to Physiotherapy interventions delivered to patients with VFF in any setting.

DATA SYNTHESIS

A narrative synthesis was conducted.

RESULTS

Thirteen studies were included with five randomised control trials, three pilot RCTs, two qualitative studies, one cross-sectional survey of clinicians, one cohort study and one prospective comparative study. Interventions most commonly reported were exercise, education or manual therapy. A large diversity of outcome measures was utilised most commonly in the spinal deformity, physical performance and balance, pain and quality of life domains.

CONCLUSION

Findings of this scoping review indicate the limited evidence to guide physiotherapists in the management of patients with VFF. The most commonly explored physiotherapy interventions were exercise, manual therapy and education. A diversity of outcome measures is utilised. Research is urgently needed, including high quality clinical trials with representative populations and studies exploring physiotherapy practice and the experience of patients with VFF.

Equivalent values between anterior vertebral height, wedge ratio, and wedge angle for evaluating vertebral mobility and deformity in osteoporotic vertebral fractures: a conventional observational study

BACKGROUND

Vertebral mobility (V-mobility) has been used to diagnose fresh osteoporotic vertebral fractures (OVFs) and determine bone union by setting cutoff values for these purposes. V-mobility is the difference in vertebral height on dynamic radiographs taken in the sitting and lateral decubitus or supine positions. The dimensions for V-mobility were presented as anterior vertebral height (Ha; mm), wedge ratio (WR; %), and wedge angle (WA; °) in previous reports. This study was performed to obtain WR and WA values equivalent to V-mobility of 1.0 mm in Ha.

METHODS

Lateral radiographs of 284 OVFs (grade 1-3 deformed vertebrae) from T11 to L2 were obtained from 77 patients with OVF. V-mobility presented as Ha, posterior vertebral height, and WA was obtained by the difference in these dimensions on dynamic radiographs. The WR and WA values equivalent to 1.0 mm in Ha were obtained by dividing the V-mobility values for WR and WA by that for Ha.

RESULTS

The mean WR values corresponding to 1.0 mm in Ha for grade 1, 2, and 3 vertebrae were 3.2% ± 1.4%, 3.2% ± 0.9%, and 3.4% ± 1.0%, respectively, and the corresponding value for grade 1-3 vertebrae was 3.3% ± 1.0%. The mean WA values corresponding to 1.0 mm in Ha for grade 1, 2, and 3 vertebrae were 1.5° ± 0.8°, 1.5° ± 0.6°, and 1.5° ± 0.8°, respectively, and the corresponding value for grade 1-3 vertebrae was 1.5° ± 0.7°.

CONCLUSIONS

The WR and WA values equivalent to V-mobility of 1.0 mm in Ha were 3.3% and 1.5°, respectively, in grade 1-3 vertebrae. These findings may be useful to secure a reliable value of V-mobility of OVFs using simultaneous measurements in three dimensions (Ha, WR, and WA) in clinical practice and to establish cutoff values for V-mobility to determine bone union.

Spinal Orthoses in the Treatment of Osteoporotic Thoracolumbar Vertebral Fractures in the Elderly: A Systematic Review With Quantitative Quality Assessment

STUDY DESIGN

Systematic review.

OBJECTIVES

Spinal orthoses are frequently used to non-operatively treat osteoporotic vertebral fractures (OVF), despite the available evidence is rare. Previously systematic reviews were carried out, presenting controversial recommendations. The present study aimed to systematic review the recent and current literature on available evidence for the use of orthoses in OVF.

METHODS

A systematic review was conducted using PubMed, Medline, EMBASE and CENTRAL databases. Identified articles including previous systematic reviews were screened and selected by three authors. The results of retrieved articles were presented in a narrative form, quality assessment was performed by two authors using scores according to the study type.

RESULTS

Thirteen studies (n = 5 randomized controlled trials, n = 3 non- randomized controlled trials and n = 5 prospective studies without control group) and eight systematic reviews were analyzed. Studies without comparison group reported improvements in pain, function and quality of life during the follow-up. Studies comparing different types of orthoses favor non-rigid orthoses. In comparison to patients not wearing an orthosis three studies were unable to detect beneficial effects and two studies reported about a significant improvement using an orthosis. In the obtained quality assessment, three studies yielded good to excellent results. Previous reviews detected the low evidence for spinal orthoses but recommended them.

CONCLUSION

Based on the study quality and the affection of included studies in previous systematic reviews a general recommendation for the use of a spinal orthosis when treating OVF is not possible. Currently, no superiority for spinal orthoses in OVF treatment was found.

2022 SPILF - Clinical Practice guidelines for the diagnosis and treatment of disco-vertebral infection in adults

These guidelines are an update of those made in 2007 at the request of the French Society of Infectious Diseases (SPILF, Société de Pathologie Infectieuse de Langue Française). They are intended for use by all healthcare professionals caring for patients with disco-vertebral infection (DVI) on spine, whether native or instrumented. They include evidence and opinion-based recommendations for the diagnosis and management of patients with DVI. ESR, PCT and scintigraphy, antibiotic therapy without microorganism identification (except for emergency situations), therapy longer than 6 weeks if the DVI is not complicated, contraindication for spinal osteosynthesis in a septic context, and prolonged dorsal decubitus are no longer to be done in DVI management. MRI study must include exploration of the entire spine with at least 2 orthogonal planes for the affected level(s). Several disco-vertebral samples must be performed if blood cultures are negative. Short, adapted treatment and directly oral antibiotherapy or early switch from intravenous to oral antibiotherapy are recommended. Consultation of a spine specialist should be requested to evaluate spinal stability. Early lifting of patients is recommended.

Compliance with wearing a thoracolumbar orthosis in nonoperative treatment of osteoporotic vertebral fractures: a prospective sensor-controlled study

BACKGROUND CONTEXT

Hyperextension orthoses (HOs) for nonoperative treatment of osteoporotic vertebral fractures (OVFs) are widely prescribed. However, the compliance, how much an HO is worn after it has been prescribed, is widely unknown.

PURPOSE

This study was performed to assess the wearing time of HOs for OVFs in a prospective blinded, sensor-controlled manner.

STUDY DESIGN / SETTING

A prospective, single blinded observational study was performed.

PATIENT SAMPLE

This study prospectively included 18 patients who were treated nonoperatively with an HO for OVFs.

OUTCOME MEASURES

The true wearing time was measured using a hidden temperature-based sensor. The patients were invited to return for regular follow-up every 2 weeks for 6 weeks, at which time clinical evaluation (including a visual analog scale for pain and the Oswestry disability questionnaire) and radiographs of the spine were performed.

METHODS

Full compliance was defined as a wearing time of 15 hours per day. Correlation between compliance and demographic differences, patient reported outcomes and radiographic changes of the vertebral structures were calculated.

RESULTS

The mean HO wearing time was 5.5±3.3 hours (37%±22% compliance). Female patients used the HO significantly longer per day than did male patients (6.5±3.2 vs 2.9±2.0 hours, p=.039). Age and body mass index had no influence on wearing behavior.

CONCLUSIONS

Overall, compliance with wearing HOs is poor and shows great variability with significant gender-dependency but not associated with BMI, age, or pain-level. Further studies are required to confirm our results that the wearing time does not have an influence on kyphotic progression of the osteoporotic fractured segment, nor on clinical outcome at short term.

Bracing and taping interventions for individuals with vertebral fragility fractures: a systematic review of randomized controlled trials with GRADE assessment

This systematic review analyzes the effects of bracing and taping after osteoporotic vertebral fractures. Spinal orthose may have positive effects on pain, but the evidence is of very low certainty. Clinical judgment is recommended when prescribing spinal orthoses.

PURPOSE

To examine the effects of bracing and taping interventions on pain, physical functioning, health-related quality of life, back extensor strength, kyphosis curvature, and adverse events in individuals with vertebral fragility fractures.

METHODS

Four databases were searched from inception up to January 2022. We included randomized controlled trials testing the effect of bracing or taping interventions compared with a non-intervention control in adults ≥ 45 years with vertebral fragility fractures. Narrative syntheses were presented for all the outcomes. We assessed the risk of bias using the Cochrane Risk of Bias Assessment Tool and the certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation.

RESULTS

Three studies were included. Soft bracing interventions exhibited inconsistent effects on pain. One study showed no difference between groups, and another study should a decrease in pain in the soft bracing group compared to the control group. Rigid bracing interventions did not have a significant change in pain between the control and intervention groups. One study demonstrated a decrease in pain at rest (VAS: - 10.8 ± 19.3) and during movement (VAS: - 20.9 ± 29.8) after a taping intervention. The other outcomes were not consistent across studies.

CONCLUSIONS

Spinal orthoses may improve pain in people with vertebral fractures; however, we cannot draw definitive conclusions on the efficacy or harms of bracing or taping due to the very low certainty evidence and the small number of studies. Effects on other outcomes are uncertain.

The clinician's guide to prevention and treatment of osteoporosis

Osteoporosis is the most common metabolic bone disease in the USA and the world. It is a subclinical condition until complicated by fracture(s). These fractures place an enormous medical and personal burden on individuals who suffer from them and take a significant economic toll. Any new fracture in an adult aged 50 years or older signifies imminent elevated risk for subsequent fractures, particularly in the year following the initial fracture. What a patient perceives as an unfortunate accident may be seen as a sentinel event indicative of bone fragility and increased future fracture risk even when the result of considerable trauma. Clinical or subclinical vertebral fractures, the most common type of osteoporotic fractures, are associated with a 5-fold increased risk for additional vertebral fractures and a 2- to 3-fold increased risk for fractures at other sites. Untreated osteoporosis can lead to a vicious cycle of recurrent fracture(s), often resulting in disability and premature death. In appropriate patients, treatment with effective antifracture medication prevents fractures and improves outcomes. Primary care providers and medical specialists are critical gatekeepers who can identify fractures and initiate proven osteoporosis interventions. Osteoporosis detection, diagnosis, and treatment should be routine practice in all adult healthcare settings. The Bone Health and Osteoporosis Foundation (BHOF) - formerly the National Osteoporosis Foundation - first published the Clinician's Guide in 1999 to provide accurate information on osteoporosis prevention and treatment. Since that time, significant improvements have been made in diagnostic technologies and treatments for osteoporosis. Despite these advances, a disturbing gap persists in patient care. At-risk patients are often not screened to establish fracture probability and not educated about fracture prevention. Most concerning, the majority of highest risk women and men who have a fracture(s) are not diagnosed and do not receive effective, FDA-approved therapies. Even those prescribed appropriate therapy are unlikely to take the medication as prescribed. The Clinician's Guide offers concise recommendations regarding prevention, risk assessment, diagnosis, and treatment of osteoporosis in postmenopausal women and men aged 50 years and older. It includes indications for bone densitometry as well as fracture risk thresholds for pharmacologic intervention. Current medications build bone and/or decrease bone breakdown and dramatically reduce incident fractures. All antifracture therapeutics treat but do not cure the disease. Skeletal deterioration resumes sooner or later when a medication is discontinued-sooner for nonbisphosphonates and later for bisphosphonates. Even if normal BMD is achieved, osteoporosis and elevated risk for fracture are still present. The diagnosis of osteoporosis persists even if subsequent DXA T-scores are above - 2.5. Ongoing monitoring and strategic interventions will be necessary if fractures are to be avoided. In addition to pharmacotherapy, adequate intake of calcium and vitamin D, avoidance of smoking and excessive alcohol intake, weight-bearing and resistance-training exercise, and fall prevention are included in the fracture prevention armamentarium. Where possible, recommendations in this guide are based on evidence from RCTs; however, relevant published data and guidance from expert clinical experience provides the basis for recommendations in those areas where RCT evidence is currently deficient or not applicable to the many osteoporosis patients not considered for RCT participation due to age and morbidity.

Effectiveness and cost-effectiveness of dynamic bracing versus standard care alone in patients suffering from osteoporotic vertebral compression fractures: protocol for a multicentre, two-armed, parallel-group randomised controlled trial with 12 months of follow-up

INTRODUCTION

Patients with osteoporosis may suffer from a fracture after minimal trauma. Osteoporotic vertebral compression fractures (OVCFs) are among the most common fractures, often leading to substantial pain. There is a need for evidence-based conservative treatment to aid in the management of OVCFs. The objective of this randomised controlled trial (RCT) is to evaluate the effectiveness and cost-effectiveness of dynamic bracing in addition to standard care for improving quality of life (QoL) in patients suffering from an OVCF.

METHODS AND ANALYSIS

Ninety-eight postmenopausal women from two academic and four community hospitals with a recent symptomatic thoracolumbar OVCF will be randomised into either the standard care or dynamic bracing group. In the dynamic bracing group, the Spinova Osteo orthosis will be used in addition to standard care. Standard care comprises pain control with analgesics, physical therapy and osteoporosis medication. The primary outcome parameter is QoL 1 year after inclusion, as measured by the Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO-41). Secondary outcome parameters are pain, pain medication used, functional disability, sagittal spinal alignment, recurrence rate of OVCFs and physical activity in daily life. A trial-based economic evaluation consisting of both cost-effectiveness analysis and cost-utility analysis will be performed based on empirical data obtained in the RCT. A process evaluation will assess the feasibility of dynamic bracing. All outcomes will be assessed at baseline, 6 weeks, 3 months, 6 months, 9 months and 12 months.

ETHICS AND DISSEMINATION

Ethical approval has been granted by the Medical Ethics Committee, University Hospital Maastricht and Maastricht University (METC azM/UM) (NL74552.068.20/METC 20-055). Patients will be included only after verification of eligibility and obtaining written informed consent. Results will be disseminated via the Dutch National Osteoporosis Patient Society and via publications and conferences.

Effect of a semi-rigid backpack type thoracolumbar orthosis on thoracic kyphosis angle and muscle performance in older adults with hyperkyphosis: a randomized controlled trial

PURPOSE

To investigate the effect of a semi-rigid backpack type thoracolumbar orthosis (TLO) on thoracic kyphosis angle (TKA) and potentially contributing factors of hyperkyphosis, including position sense and back muscle strength and endurance.

METHOD

This randomized, controlled trial was conducted on 48 older adults with hyperkyphosis, randomly allocated to an experimental or control group. The experimental group wore a semi-rigid TLO for 3 consecutive months. The control group received no external support or exercise. Thoracic kyphosis angle (TKA), joint position sense, back muscle strength and endurance were evaluated at the baseline and at the end of week 6 and week 12.

RESULTS

The two-way (group × time) interactions were significant in terms of TKA (F = 37.88, p ≤ 0.001, η_p² = 0.45), muscle strength (F = 26.005, p ≤ 0.001, η_p² = 0.36), muscle endurance measured via load cell (F = 3.417, p = 0.039, η_p² = 0.06), and endurance holding time of Ito test (F = 3.629, p = 0.045, η_p² = 0.07). A further analysis using one-way repeated measures of ANOVA showed that TKA, muscle strength and endurance were significantly improved in the experimental group. Also, two-way interactions were significant for absolute error and variable error of trunk neutral repositioning test from a trunk flexed and/or extended position for global components and horizontal components trunk repositioning test.

CONCLUSION

Wearing a semi-rigid backpack type TLO even from an unknown brand for short periods during the day (e.g., 2-4 h) over 3 months not only modifies kyphotic posture but also can enhance back muscle performance in older adults with hyperkyphosis. IMPLICATIONS FOR REHABILITATIONPrescription of a semi-rigid backpack type thoracolumbar orthosis for older adults has no adverse effects such as muscle weakness if it is applied for short periods during the day.A semi-rigid backpack thoracolumbar orthosis can prevent position sense degradation in older adults with hyperkyphosis.A semi-rigid backpack type thoracolumbar orthosis may counteract trunk flexion and kyphotic posture by applying the biomechanical principles of the three-point pressure system.Improvement in spinal alignment resulting from wearing thoracolumbar orthosis should not occur in exchange for muscle deconditioning.

Rehabilitation in Advanced Cancer Patients with Bone Metastases and Neural Compromise: Current Status and Future Directions

PURPOSE OF REVIEW

This review aimed to increase the understanding of oncologists and physiatrists about the necessity, efficacy, and safety of rehabilitation in advanced cancer patients with bone metastases and neural compromise.

RECENT FINDINGS

Recently, there are growing evidence supporting the safety and efficacy of rehabilitation in patients with bone metastases and neural compromise. Despite the potential benefits of rehabilitation, however, rehabilitative services are considerably underutilized in clinical practice. Many oncologists are not familiar with functional issues and have limited understanding of the available rehabilitative services. Moreover, medical professionals, even physiatrists, have uncertainties and concerns about skeletal complications and often regard rehabilitation as a contraindication in this patient group. This review aimed to raise awareness on the role of rehabilitation in the continuum of cancer treatment, to improve its use in clinical practice. A multidisciplinary team approach involving physiatrist may facilitate integration of relevant clinicians.

Wearing an Activating Spinal Orthosis and Physical Training in Women With Osteoporosis and Back Pain: A Postintervention Follow-Up Study

Objective

To assess the duration of benefits on back pain and back extensor strength in women with osteoporosis who had previously participated in a randomized controlled trial (RCT) involving either exercise or wearing a spinal orthosis.

Design

A 6-month postintervention follow-up of women who were involved in the interventions in the RCT.

Setting

The study was conducted in a primary health care center in Stockholm, Sweden.

Participants

In this follow-up study 31 women participated in the spinal orthosis group, and 31 women participated in the exercise group, with a median age of 76 years in both groups (N=62). All women were diagnosed as having osteoporosis, had back pain with or without vertebral fracture, and were 60 years or older, which were the inclusion criteria in the RCT.

Interventions

The participants received no controlled supervision. The spinal orthosis group was asked to wear the orthosis, and the training group was asked to follow an exercise program for another 6 months voluntarily.

Main Outcome Measures

Back extensor strength was measured with a computerized device; back pain was estimated by the visual analog scale and by Borg CR-10.

Results

After 6 months there were no significant differences between the groups in back extensor strength or back pain. Analyses within the groups showed that achieved results during 6 months intervention in the RCT were maintained after 6 months of voluntary use of the spinal orthosis and training. In the spinal orthosis group, back extensor strength mean was 81.7 N, and back pain median was 3 mm. In the training group back extensor strength mean was 72.8 N, and back pain median was 3 mm. There were no changes for any other measurements performed.

Conclusions

Voluntary use of the spinal orthosis or exercise during a 6-month follow-up period maintained the increase in back extensor muscle strength obtained during the RCT. Estimation of back pain was not influenced. This indicates that the women had continued to use the spinal orthosis and exercise.

[Rehabilitation in rheumatic diseases and osteoporosis-a multidisciplinary task]

Advances in medications and changes in therapeutic options have significantly reduced limitations in functional capacity and quality of life for patients with rheumatic diseases and osteoporosis, but there is still a large number of patients in whom the diseases do not take the desired course. Older rheumatic patients also often have comorbidities that require a multidisciplinary and multimodal approach to therapy. Rehabilitation measures are, therefore, an important part of the treatment concept for these patients in order to maintain their functional health, social participation, and, in the case of those who are still working, in particular their gainful employment. They can help to limit sequelae, preserve existing functions, reduce pain, and maintain the quality of life of those affected. The article aims to provide an overview of the rehabilitative therapy concept and the level of evidence for individual forms of therapy.

A comparison of the effectiveness of three types of trunk orthoses on the balance performance of older people with osteoporotic hyperkyphosis: A cross-over study

BACKGROUND

Orthotic immobilization is an early treatment for osteoporotic vertebral fracture at the hyperkyphotic thoracic spine.

OBJECTIVE

This exploratory study compared the immediate impact of three types of trunk orthoses on the balance parameters of older people with osteoporosis hyperkyphosis.

METHODS

Twenty older people (aged 60-65 years) with osteoporosis kyphosis and a history of falls participated in a pilot cross-over study. Four randomized comparisons were carried out, including either soft, semi-rigid, and rigid trunk orthoses worn on the participants compared to "no orthosis" as the control condition. Kyphosis angle, Forward Reach Test, Timed Up and Go test, and postural stability during standing on a force plate were recorded and compared between study conditions using one-way repeated measures analysis of variance test.

RESULTS

All orthoses significantly reduced the kyphosis angle (p < 0.01). None of the orthoses has a significant change in the Timed Up and Go test (p > 0.01). Rigid orthosis significantly reduced the forward reach compared to "no orthosis" (p = 0.003, 95% CI: 1.08-6.3 cm). None of the orthosis induced a significant change in postural sway velocity in anteroposterior and mediolateral directions compared to the control condition (p > 0.01).

CONCLUSION

These findings suggest that using rigid orthosis in older people with osteoporosis hyperkyphosis reduces the balance performance.

Population-based Analysis for Risk of Suicide Death in Elderly Patients after Osteoporotic Fracture: a Nested Case-Control Study

BACKGROUND

The purpose of study was to investigate the incidence rate of suicide in elderly patients with osteoporotic fractures in a nested case-control model and to analyze the change in the risk of suicide death over time after each osteoporotic fracture.

METHODS

We used the National Health Insurance Service-Senior cohort of South Korea. Suicide cases and controls were matched based on sex and age at the index date. Controls were randomly selected at a 1:5 ratio from the set of individuals who were at risk of becoming a case at the time when suicide cases were selected. Conditional logistic regression analysis was performed to evaluate the association between each type of osteoporotic fracture and the risk of suicide death.

RESULTS

Three thousand seventy suicide cases and 15,350 controls were identified. Patients with hip fracture showed an increased risk of suicide death within 1 year of fracture (adjusted odds ratio [aOR] = 2.64; 95% confidence interval [CI], 1.57-4.46; P < 0.001) compared to controls. However, the increased risk of suicide death in patients with hip fracture lasted up to 2 years (aOR = 1.59; 95% CI, 1.04-2.41; P = 0.031). Spine fracture increased the risk of suicide deaths for all observation periods. There was no evidence that humerus fracture increased the risk of suicide death during the observational period. Radius fracture increased only the risk of suicide death within 2 years of fracture (aOR = 1.43; 95% CI, 0.74-2.77; P = 0.282).

CONCLUSION

There were noticeable differences in both degree and duration of increased suicide risks depending on the type of osteoporotic fracture. Mental stress and suicide risk in elderly patients after osteoporotic fracture should be assessed differently depending on the types of fracture.

Spinal Orthoses Prescription for Vertebral Fragility Fractures by Italian Physical and Rehabilitation Medicine Physicians: The SPIN-VER Survey

Vertebral fragility fractures (VFFs) are the most common type of osteoporotic fractures, related to pain and disability. In this scenario, physical and rehabilitative medicine (PRM) physicians prescribe a patient-tailored rehabilitation plan, including spinal orthoses. However, there is a high heterogeneity in the clinical indications of spinal orthoses. Thus, the aim of this survey was to investigate common clinical practice in terms of the prescription of spinal orthoses. This nationwide cross-sectional survey recruited Italian PRM physicians commonly involved in the management of patients with VFFs. One hundred twenty-six PRM physicians completed the survey. The results showed that most PRM physicians prescribe spinal orthoses in outpatients suffering from VFFs (n = 106; 83.9%). The most prescribed spinal orthosis for acute VFF patients was the three-point rigid orthosis (n = 64; 50.8%), followed by the semirigid thoraco-lumbar orthosis (n: 20; 15.9%). However, most PRM physicians prescribed dynamic orthoses in outpatients with chronic VFFs (n = 66; 52.4%). Albeit that a correct management of VFFs is mandatory to improve pain and reduce disability, our findings highlighted uncertainty in the type of spinal orthosis prescription in both the acute and chronic VFF phase. Therefore, high-quality research trials are warranted to provide clear recommendations for the correct clinical management of VFF.

The Role of Spinal Orthoses in Osteoporotic Vertebral Fractures of the Elderly Population (Age 60 Years or Older): Systematic Review

STUDY DESIGN

Systematic review.

OBJECTIVE

Spinal orthoses have been generally used in the management of osteoporotic vertebral fractures in the elderly population with purported positive biomechanical and functional effects. To our knowledge, this is the first systematic review of the literature examining the role of spinal orthoses in osteoporotic elderly patients who sustain low energy trauma vertebral fractures.

METHODS

A systematic literature review adherent to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted. Methodical searches utilizing MEDLINE, EMBASE, Google Scholar, and Cochrane Databases was performed.

RESULTS

Of the 2019 articles initially retrieved, 7 published articles (4 randomized controlled trials and 3 prospective cohort studies) satisfied the inclusion criteria. Five studies reported improvement in quantitative measurements of spinal column stability when either a rigid or semirigid orthosis was used, while 1 study was equivocal. The studies also showed the translation of biomechanical benefit into significant functional improvement as manifested by improved postural stability and reduced body sway. Subjective improvement in pain scores and quality of life was also noted with bracing.

CONCLUSION

The use of spinal orthoses in neurologically intact elderly patients aged 60 years and older with osteoporotic compression vertebral fractures results in improved biomechanical vertebral stability, reduced kyphotic deformity, enhanced postural stability, greater muscular strength and superior functional outcomes.

Prevention and management of osteoporotic fractures by non-physician health professionals: a systematic literature review to inform EULAR points to consider

Objective

To perform a systematic literature review (SLR) about the effect of non-pharmacological interventions delivered by non-physician health professionals to prevent and manage osteoporotic fractures.

Methods

Eight clinical questions based on two criteria guided the SLR: (1) adults≥50 years at high risk of osteoporotic fracture and (2) interventions delivered by non-physician health professionals to prevent and manage osteoporotic fractures. Interventions focused on diagnostic procedures to identify risk of falling, therapeutic approaches and implementation strategies. Outcomes included fractures, falls, risk of falling and change in bone mineral density. Systematic reviews and randomised controlled trials were preferentially selected. Data were synthesised using a qualitative descriptive approach.

Results

Of 15 917 records, 43 articles were included. Studies were clinically and methodologically diverse. We identified sufficient evidence that structured exercise, incorporating progressive resistance training delivered to people who had undergone hip fracture surgery, and multicomponent exercise, delivered to people at risk of primary fracture, reduced risk of falling. The effectiveness of multidisciplinary fracture liaison services in reducing refracture rate was confirmed. There was insufficient evidence found to support the effectiveness of nutrients and falls prevention programmes in this patient population.

Conclusion

Despite study heterogeneity, our SLR showed beneficial effects of some interventions delivered by non-physician health professionals and the positive impact of multidisciplinary team working and patient educational approaches to prevent and manage osteoporotic fractures. These results informed a EULAR taskforce that developed points to consider for non-physician health professionals to prevent and manage osteoporotic fractures.

Review of Current Spinal Robotic Orthoses

Osteoporotic spine fractures (OSF) are common sequelae of osteoporosis. OSF are directly correlated with increasing age and incidence of osteoporosis. OSF are treated conservatively or surgically. Associated acute pain, chronic disabilities, and progressive deformities are well documented. Conservative measures include a combination of initial bed rest, analgesia, early physiotherapy, and a spinal brace (orthosis), with the aim for early rehabilitation to prevent complications of immobile state. Spinal bracing is commonly used for symptomatic management of OSF. While traditional spinal braces aim to maintain the neutral spinal alignment and reduce the axial loading on the fractured vertebrae, they are well known for complications including discomfort with reduced compliance, atrophy of paraspinal muscles, and restriction of chest expansion leading to chest infections. Exoskeletons have been developed to passively assist and actively augment human movements with different types of actuators. Flexible, versatile spinal exoskeletons are designed to better support the spine. As new technologies enable the development of motorized wearable exoskeletons, several types have been introduced into the medical field application. We have provided a thorough review of the current spinal robotic technologies in this paper. The shortcomings in the current spinal exoskeletons were identified. Their limitations on the use for patients with OSF with potential improvement strategies were discussed. With our current knowledge of spinal orthosis for conservatively managed OSF, a semi-rigid backpack style thoracolumbar spinal robotic orthosis will reduce spinal bone stress and improve back muscle support. This will lead to back pain reduction, improved posture, and overall mobility. Early mobilization is an important part of management of patients with OSF as it reduces the chance of developing complications related to their immobile state for patients with OSF, which will be helpful for their recovery.

Orthosis in Thoracolumbar Fractures: A Systematic Review and Meta-analysis of Randomized Controlled Trials

STUDY DESIGN

Systematic review and meta-analysis of randomized controlled trial (RCT).

OBJECTIVE

The aim of this study was to evaluate radiological and clinical outcomes of acute traumatic thoracolumbar fractures in skeletally mature patients treated with orthosis, versus no immobilization.

SUMMARY OF BACKGROUND DATA

Orthosis is traditionally used in conservative treatment of thoracolumbar fractures. However, recent studies suggest no benefit, and a possible negative impact in recovery.

METHODS

Databases were searched from inception to June 2019. Studies were selected in two phases by two blinded reviewers; disagreements were solved by consensus. Inclusion criteria were: RCT; only patients with acute traumatic thoracolumbar fractures; primary conservative treatment; comparison between orthosis and no orthosis. Exclusion criteria were inclusion of nonacute fractures, patients with other significant known diseases and comparison of groups different than use of an orthosis. Two independent reviewers performed data extraction and quality assessment. Fixed-effects models were used upon no heterogeneity, and random-effects model in the remaining cases. A previous plan for extraction of radiological (kyphosis progression; loss of anterior height) and clinical (pain; disability; length of stay) outcomes was applied. PRISMA guidelines were followed.

RESULTS

Eight articles/five studies were included (267 participants). None reported significant differences in pain, kyphosis progression, and loss of anterior height. One reported a better ODI with orthosis at 12 but not at 24 weeks. No other study reported differences in disability. All authors concluded an equivalence between treatments.Meta-analysis showed a significant increase of 3.47days (95% confidence interval 1.35-5.60) in mean admission time in orthosis group. No differences were found in kyphosis at 6 and 12 months; kyphosis progression between 0 to 6 and 0 to 12 months; loss of anterior height 0 to 6 months; VAS for pain at 6 months; VAS change 0 to 6 months.

CONCLUSION

Orthosis seems to add no benefit in conservative treatment of acute thoracolumbar fractures. This should be considered in guidelines and reviews of health care policies.

What Is the Difference in the Risk of Suicide Death Between Spine Fracture in Patients Older Than 65 Years and Matched Controls? A Large-database Study from South Korea

BACKGROUND

Pain and kyphotic deformity after spinal fractures can result in a decrease in a patient's physical function and quality of life. Furthermore, physical illness, such as respiratory compromise, or mental illness, including depression, may be exacerbated by a spinal fracture. Complications caused by spinal fractures and old age are risk factors for suicide, but studies on these patients are rare.

QUESTIONS/PURPOSES

(1) What is the incidence rate of death by suicide after a spinal fracture in patients older than 65 years? (2) How much does the risk of death by suicide increase in patients older than 65 years who have spine fractures compared with well-matched controls? (3) How does this risk change as a function of increasing time after injury?

METHODS

Spinal fractures in patients older than 65 years and matched controls were selected from the National Health Insurance Service-Senior cohort (NHIS-Senior) of South Korea. The NHIS-Senior consists of 558,147 people selected by 10% simple random sampling method from a total of 5.5 million people 60 and older in 2002; all people were followed through 2015. A total of 31,357 patients with spine fractures and their 62,714 matched controls remained in the study. The mean follow-up time was 4.3 ± 3.0 years (135,229 person-years) in the spine fracture group and 4.6 ± 3.0 years (290,096 person-years) in the matched control group. We matched the groups for demographic factors such as age, gender, Charlson Comorbidity Index score, medication history, medical history, preoperative disability, number of hospital admissions, as well as socioeconomic factors such as household income level, residential district, and type of national health insurance using a 1:2 risk set propensity score matching by a nearest-neighbor matching algorithm with a maximum caliber of 0.1 of the hazard components. The incidence rate of suicide and the 95% confidence interval were calculated based on a generalized linear model with a Poisson distribution. The effect size was presented as a hazard ratio (HR) using Cox's proportional hazard model with robust variance estimator that accounts for clustering within matched pairs.

RESULTS

The overall risk of death by suicide throughout the surveillance period, expressed as an incidence rate, was 116 per 100,000 person-years in spinal fracture (157 deaths by suicide over 135,229 person-years). Throughout the entire surveillance period, the risk of death by suicide was greater among patients with spinal fractures than it was in the control group (HR 1.8 [95% CI 1.5 to 2.2]; p < 0.01). This difference was greatest in the first 365 days after the fracture (HR 2.5 [95% CI 1.6 to 3.8]; p < 0.01) (45 deaths by suicide, incidence rate: 156 per 100,000 person-years in spinal fracture). The risk of suicide death in patients with spine fracture from 365 days to the last follow-up was also higher than that of matched controls (HR 1.6 [95% CI 1.3 to 2.1]; p < 0.01).

CONCLUSIONS

Considering the substantially increased risk of death by suicide in patients with spine fractures who are older than 65 years, surgeons should consider offering psychiatric evaluation and management more frequently, particularly in patients with chronic pain, functional disability, and depressive mood. Future studies should investigate the underlying causes of suicide, such as deteriorating socioeconomic support or depression, and whether early initiation of psychological support after injury can reduce the suicide rate.

Effect of a Spinomed orthosis on balance performance, spinal alignment, joint position sense and back muscle endurance in elderly people with hyperkyphotic posture: A randomized controlled trial

BACKGROUND

Hyperkyphosis may cause balance impairment in elderly people. Although the effectiveness of orthoses for improving balance in hyperkyphotic elderly people has received much attention, the mechanisms by which devices affect balance remain unknown.

OBJECTIVES

The objective of this study was to evaluate changes in balance performance, thoracic kyphosis angle, craniovertebral angle, back muscle endurance and joint position sense after 3 months of wearing a Spinomed orthosis. The study also included a secondary exploratory analysis to determine whether changes in any of the above-mentioned outcome measures can predict balance performance improvement in elderly people with hyperkyphosis.

STUDY DESIGN

Parallel group randomized controlled trial.

METHODS

In total, 44 hyperkyphotic elderly people were randomly allocated to an experimental group, who wore a Spinomed orthosis and a control group, who did not. No other treatment or change in physical activity was permitted during the study. A blinded assessor evaluated thoracic kyphosis angle, joint position sense, craniovertebral angle, back muscle endurance, Timed Up and Go Test time and Berg Balance Scale score at baseline and after 5, 9 and 13 weeks. All dependent variables were measured without the orthosis and analyzed separately using a 2 × 4 (time × group) mixed model analysis of variance. Based on the results of correlation analysis, thoracic kyphosis angle, back muscle endurance and joint position sense were selected as independent variables in a stepwise multiple regression model.

RESULTS

The two-way (group × time) interactions were significant in terms of Berg Balance Scale (F = 11.6, P ⩽ 0.001, ηp2=0.59), Timed Up and Go Test (F = 3.74, P = 0.013, ηp2=0.46), thoracic kyphosis angle (F = 43.39, P ⩽ 0.001, ηp2=0.96), craniovertebral angle (F = 5.245, P = 0.002, ηp2=0.59) and joint position sense (F = 4.44, P = 0.005, [Formula: see text]). The two-way interaction was not significant in terms of back muscle endurance; however, the main effect of group was significant for this variable (F = 3.85, P = 0.025). Stepwise multiple regression showed that thoracic kyphosis angle and joint position sense were significant determinants of Timed Up and Go Test time (R² = 0.155, P = 0.037 and R² = 0.292, P = 0.012, respectively).

CONCLUSION

Wearing a Spinomed orthosis for 3 months improved the posture, position sense and muscle performance of hyperkyphotic elderly people. Orthoses may improve balance performance by correcting spinal alignment and increasing proprioceptive information.

Management of hospitalised osteoporotic vertebral fractures

Management of hospitalised osteoporotic vertebral fracture patients was explored across all major trauma orthopaedic hospitals in Ireland. Findings, based on a survey of orthopaedic doctors and physiotherapists, indicate a lack of standardised clinical care pathways. This study will inform development of clinical audit mechanisms and health service development for this large and growing fracture population in both Ireland and internationally.

PURPOSE

To explore the management of hospitalised vertebral fragility fracture (VFF) patients in Ireland.

METHODS

A cross-sectional survey of orthopaedic doctors (specialist registrar level) and physiotherapists was conducted across all hospitals with major orthopaedic trauma units in Ireland. Data were analysed using descriptive statistics in SPSS (V24).

RESULTS

Responses were achieved from 100% (n = 16) of the hospitals (42 individual physiotherapists and 47 orthopaedic doctors). Conservative management was usual with both orthopaedic doctors (n = 37, 79%) and physiotherapists (n = 40, 96%) reporting prescription of bracing as common practice despite a lack of underpinning evidence. A majority (87%) of the doctors believed osteoporosis medications should commence prior to discharge from the acute setting, but 68% did not agree that responsibility for coordination and delivery of bone health assessment and fracture risk management rested with them. A majority (72%) of physiotherapists reported an absence or were unsure regarding existence of fracture liaison services. 73% of physiotherapists reported prescribing an inpatient or home (78%) exercise programme, including mobility, strength and balance exercise though detail on dose and adherence remain unknown. Wide variance in referral patterns to multi-disciplinary team (MDT) members existed although 79% of orthopaedic doctors supported an MDT approach.

CONCLUSION

Clinical care pathways for the hospitalised VFF population lack standardisation in Ireland. Key challenges reported by orthopaedic doctors and physiotherapists relate to pain management, osteoporosis medication prescription, clarity on indications for bracing and a lack of fracture liaison services. Clinical guidelines, defined clinical care pathways and high-quality clinical research trials are required for VFF management.

Experiences of using an activating spinal orthosis in women with osteoporosis and back pain in primary care

Women with osteoporosis and back pain took part in focus group interviews and described their experiences of using and handling an activating spinal orthosis. The women described the back orthosis as being like a "close friend", a support in everyday life and a reminder to maintain a good posture.

PURPOSE

The purpose of this study was to describe and gain a deeper understanding of the views of older women with osteoporosis and back pain seeking primary care regarding their use and handling of an activating spinal orthosis.

METHOD

We chose a qualitative method whereby information was gathered via focus group interviews and analysed using inductive content analysis. Women who previously participated in a randomised controlled trial and wore an activating spinal orthosis for 6 months were asked. Out of 31 women, 18 agreed to participate. Five focus group interviews were conducted.

RESULTS

The analysis resulted in an overall theme in which the experiences of wearing the spinal orthosis were described as follows: "A well-adapted spinal orthosis could develop into a long-lasting friendship that provided support and help in daily life". The overall theme was based on three main categories: impact on daily life, individual adaptation and personal relationship. The main categories were well differentiated from each other but had an interdependency. All three categories involved cases in which the spinal orthosis was perceived as relieving symptoms and making daily life easier, as well as when it was perceived as being hard to manage and provided no symptom relief.

CONCLUSION

In older women with osteoporosis and back pain, an activating spinal orthosis could be perceived as being a "close friend" and a support in everyday life. To facilitate acceptance of the spinal orthosis, it was important for it to be well adapted and for follow-ups to be carried out regularly.

Exercise or manual physiotherapy compared with a single session of physiotherapy for osteoporotic vertebral fracture: three-arm PROVE RCT

BACKGROUND

A total of 25,000 people in the UK have osteoporotic vertebral fracture (OVF). Evidence suggests that physiotherapy may have an important treatment role.

OBJECTIVE

The objective was to investigate the clinical effectiveness and cost-effectiveness of two different physiotherapy programmes for people with OVF compared with a single physiotherapy session.

DESIGN

This was a prospective, adaptive, multicentre, assessor-blinded randomised controlled trial (RCT) with nested qualitative and health economic studies.

SETTING

This trial was based in 21 NHS physiotherapy departments.

PARTICIPANTS

The participants were people with symptomatic OVF.

INTERVENTIONS

Seven sessions of either manual outpatient physiotherapy or exercise outpatient physiotherapy compared with the best practice of a 1-hour single session of physiotherapy (SSPT).

MAIN OUTCOME MEASURES

Outcomes were measured at 4 and 12 months. The primary outcomes were quality of life and muscle endurance, which were measured by the disease-specific QUALEFFO-41 (Quality of Life Questionnaire of the European Foundation for Osteoporosis - 41 items) and timed loaded standing (TLS) test, respectively. Secondary outcomes were (1) thoracic kyphosis angle, (2) balance, evaluated via the functional reach test (FRT), and (3) physical function, assessed via the Short Physical Performance Battery (SPPB), 6-minute walk test (6MWT), Physical Activity Scale for the Elderly, a health resource use and falls diary, and the EuroQol-5 Dimensions, five-level version.

RESULTS

A total of 615 participants were enrolled, with 216, 203 and 196 randomised by a computer-generated program to exercise therapy, manual therapy and a SSPT, respectively. Baseline data were available for 613 participants, 531 (86.6%) of whom were women; the mean age of these participants was 72.14 years (standard deviation 9.09 years). Primary outcome data were obtained for 69% of participants (429/615) at 12 months: 175 in the exercise therapy arm, 181 in the manual therapy arm and 173 in the SSPT arm. Interim analysis met the criteria for all arms to remain in the study. For the primary outcomes at 12 months, there were no significant benefits over SSPT of exercise [QUALEFFO-41, difference -0.23 points, 95% confidence interval (CI) -3.20 to 1.59 points; p = 1.000; and TLS test, difference 5.77 seconds, 95% CI -4.85 to 20.46 seconds; p = 0.437] or of manual therapy (QUALEFFO-41, difference 1.35 points, 95% CI -1.76 to 2.93 points; p = 0.744; TLS test, difference 9.69 seconds (95% CI 0.09 to 24.86 seconds; p = 0.335). At 4 months, there were significant gains for both manual therapy and exercise therapy over SSPT in the TLS test in participants aged < 70 years. Exercise therapy was superior to a SSPT at 4 months in the SPPB, FRT and 6MWT and manual therapy was superior to a SSPT at 4 months in the TLS test and FRT. Neither manual therapy nor exercise therapy was cost-effective relative to a SSPT using the threshold of £20,000 per quality-adjusted life-year. There were no treatment-related serious adverse events.

CONCLUSIONS

This is the largest RCT to date assessing physiotherapy in participants with OVFs. At 1 year, neither treatment intervention conferred more benefit than a single 1-hour physiotherapy advice session. The focus of future work should be on the intensity and duration of interventions to determine if changes to these would demonstrate more sustained effects.

Hybrid stabilization of unstable osteoporotic thoracolumbar vertebral body fractures: clinical and radiological outcome after a mean of 4 years

PURPOSE

The aim of this study was to evaluate midterm results after hybrid stabilization of unstable osteoporotic fractures of the thoracolumbar junction.

METHODS

This retrospective study was performed at a level I trauma center. A total of 113 patients aged 61 and older were stabilized using hybrid stabilization consisting of short-segmental posterior instrumentation and augmentation of the fractured vertebral body after suffering an unstable osteoporotic vertebral body fracture at the thoracolumbar spine. All patients were treated by hybrid stabilization. The primary outcome parameters were the ODI score and loss of reduction. Secondary radiological outcome parameters were the sagittal alignment parameters.

RESULTS

Seventy-two women and 41 men (74.6 ± 6.8 years) were included. Sixty-nine patients (61%) were re-evaluated after a mean of 48 months. Seventeen patients have died during the follow-up period (15%). A total of five in-patient complications were documented (4.4%). Additionally, 12 patients (17.4%) suffered from further osteoporotic vertebral body fractures affecting vertebral bodies of different levels. The average ODI score at the final follow-up was 29.9 (± 22.0). Thereby, 66.6% of all patients had low to moderate limitations. The average regional sagittal loss of reduction was 7.4% (± 5.6%). Loss of reduction was below 10° in 78% of the patients. There were statistically significant correlations between the loss of reduction and the ODI score, pelvic incidence and latest Cobb angle, and between the ODI scores and the lumbar lordosis.

CONCLUSIONS

The majority of patients had low or moderate limitations and low to moderate reduction loss. Thereby, high loss of reduction correlated directly with inferior outcomes. These slides can be retrieved under Electronic Supplementary Material.

Comparison of Rigid and Soft-Brace Treatments for Acute Osteoporotic Vertebral Compression Fracture: A Prospective, Randomized, Multicenter Study

While bracing is the standard conservative treatment for acute osteoporotic compression fracture, the efficacy of different brace treatments has not been extensively studied. We aimed to clarify and compare the preventive effect of the different brace treatments on the deformity of the vertebral body and other clinical results in this patient cohort. This multicenter nationwide prospective randomized study included female patients aged 65–85 years with acute one-level osteoporotic compression fractures. We assigned patients within four weeks of injury to either a rigid-brace treatment or a soft-brace treatment. The main outcome measure was the anterior vertebral body compression percentage at 48 weeks. Secondary outcome measures included scores on the European Quality of Life-5 Dimensions (EQ-5D), visual analog scale (VAS) for lower back pain, and the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ). A total of 141 patients were assigned to the rigid-brace group, whereas 143 patients were assigned to the soft-brace group. There were no statistically significant differences in the primary outcome and secondary outcome measures between groups. In conclusion, among patients with fresh vertebral compression fractures, the 12-week rigid-brace treatment did not result in a statistically greater prevention of spinal deformity, better quality of life, or lesser back pain than soft-brace.

The Prognostic Significance of Pedicle Enhancement from Contrast-enhanced MRI for the Further Collapse in Osteoporotic Vertebral Compression Fractures

STUDY DESIGN

A retrospective observational study.

OBJECTIVE

The aim of this study was to investigate the prognostic significance of contrast-enhanced magnetic resonance imaging (MRI) for detecting pedicle enhancement and predicting future collapse in patients with acute benign osteoporotic vertebral compression fracture (OVCF).

SUMMARY OF BACKGROUND DATA

Traditional morphological classification regarding compression versus burst fractures cannot accurately anticipate the prognosis of further collapse. Identifying subgroups with a higher risk for further collapse may be beneficial in determining the treatment modality, which should be decided immediately after the injury.

METHODS

One hundred fourteen patients with benign OVCFs who, at the onset, underwent contrast-enhanced spine MRI between 2003 and 2016 were retrospectively analyzed. Patients were recruited on the basis of predefined inclusion and exclusion criteria. The primary outcome was the compression progression rate; other potential variables included demographic and clinical characteristics, initial compression rates, and kyphotic angles. In addition, other structural abnormalities on MRI were assessed. The compression progression rates were compared according to pedicle enhancement, and the prognostic significance of pedicle enhancement for further collapse were analyzed.

RESULTS

Further compression progression rates were significantly higher in the pedicle-enhanced (PE) group than in the nonenhanced (NE) group. Multivariate logistic analysis revealed that pedicle enhancement may be associated with further compression progression ≥10%. The vertebral augmentation (VAG) protective effect against collapse was only significant within the PE group, while bone densitometry and patients' mobility were significant only within the NE group. The log-rank test revealed a statistically significant difference in the rates of further collapse ≥10% during the 1 year between the groups.

CONCLUSION

Sign of pedicle enhancement is a potential risk factor for further compression progression. Contrast-enhanced MRI should be performed at the onset to better determine the future risk of collapse and to choose a better treatment modality for benign OVCF patients.

Application of Cortical Bone Trajectory Screws in Elderly Patients with Lumbar Spinal Tuberculosis

OBJECTIVE

To investigate the clinical efficacy of cortical bone trajectory (CBT) screws in the treatment of elderly patients with lumbar spinal tuberculosis.

METHODS

A total of 45 elderly patients with lumbar spinal tuberculosis were allocated to 1 groups based on different surgical methods: 22 patients in group A received posterior CBT screw fixation combined with anterior debridement with a small incision and bone grafting, and 23 patients in group B underwent posterior pedicle screw fixation combined with anterior debridement with a small incision and bone grafting. The intraoperative blood loss, postoperative drainage volumes, Cobb angles, visual analogue scale scores, erythrocyte sedimentation rates (ESRs), and Frankel grades before and after surgery were analyzed. The surgical complications and spinal fusion were also assessed.

RESULTS

After a 3-month follow-up, 2 patients in group A and 3 patients in group B experienced anterior psoas muscle abscesses, which were cured by a second surgery. The remaining patients were healed by the first surgery. Spinal fusion after bone graft required 3 to 8 months (average, 4.9 months). There were no significant differences in surgery time, blood loss, drainage volume, and hospital stay between the 2 groups. The visual analogue scale scores, Cobb angles, ESRs, and Frankel grades were significantly improved after surgery in both groups.

CONCLUSION

The CBT screws were not inferior to traditional pedicle screws. The application of CBT- screws fixation combined with anterior debridement with a small incision and bone grafting was an effective and safe method to treat elderly patients with lumbar spinal tuberculosis.

Effects of postural taping on pain, function and quality of life following osteoporotic vertebral fractures-A feasibility trial

OBJECTIVE

Osteoporotic vertebral fractures (OVFs) are common and present a significant burden to patients and healthcare services. Poor posture can increase vertebral pressure, pain and the risk of further fractures. The aim of the present study was to investigate the effects of postural taping on pain, function and quality of life when used in addition to usual care.

METHODS

A feasibility randomized, controlled trial was carried out in men and women with at least one clinically diagnosed painful OVF. Participants were randomly allocated to use an adhesive postural taping device at home for 4 weeks or to continue with usual care. Outcomes assessed at baseline and 4 weeks included pain at rest and on movement (visual analogue scales [VASs]), and function and quality of life (Quality of Life Questionnaire of the European Foundation for Osteoporosis [QUALEFFO]). Health resource use and acceptability were explored using a specifically designed questionnaire.

RESULTS

Twenty-four participants completed the trial (taping, n = 13; control, n = 11). Groups were comparable in age, although the control group contained more men (n = 3 versus n = 0) and scored slightly lower on most outcome measures at baseline. Descriptive analysis favoured the taping group for most outcome measures. Effect sizes were small to medium (0.37, 0.45 and 0.66 for VAS rest, VAS movement and QUALEFFO, respectively).

CONCLUSIONS

The taping device demonstrated potential to improve pain and function. However, the findings need to be replicated in an appropriately powered study. The study procedures were largely acceptable. A more extensive pilot trial is recommended prior to a definitive trial.

Effect of spinal orthoses and postural taping on balance, gait and quality of life in older people with thoracic hyperkyphosis: protocol for a systematic review and meta-analysis

INTRODUCTION

Thoracic hyperkyphosis is one of the most common spinal disorders in older people, creating impairment, postural instability, gait disorders and a reduced quality of life. The use of spinal orthoses and/or postural taping may be feasible conservative interventions, but their efficacy is uncertain. The aim of this review is therefore to investigate the effectiveness of spinal orthoses and taping on the balance and gait of older people with hyperkyphosis.

METHODS AND ANALYSIS

We will include randomised controlled trials and clinical trial studies which assess the efficacy of spinal orthoses and taping using the WHO International Classification of Functioning, Disability and Health (ICF) outcome measures in older people with hyperkyphosis of the thoracic spine. A search will be performed in PubMed, SCOPUS, ISI Web of Knowledge, CENTRAL, EMBASE, CINAHL, AMED, PEDro, REHAB DATA and RECAL databases with no restriction of language. Two independent reviewers will perform the study selection and data extraction. Quality assessment will be implemented using modified Down and Black checklists. Publication bias and data synthesis will be assessed by funnel plots, Begg's and Egger's tests, and plots using STATA software V.12.1 version.

ETHICS AND DISSEMINATION

No ethical issues are predicted. These findings will be published in a peer reviewed journal and presented at national and international conferences.

Initial hospitalization with rigorous bed rest followed by bracing and rehabilitation as an option of conservative treatment for osteoporotic vertebral fractures in elderly patients: a pilot one arm safety and feasibility study

We assessed the safety and feasibility of a unified conservative treatment protocol for osteoporotic vertebral fractures in the elderly patients with a 24-week follow-up. Our results showed that initial hospitalization with rigorous bed rest followed by a rehabilitation program using a Jewett brace was safe and feasible in managing patients.

PURPOSE

The purpose of this study was to prove the safety and feasibility of a unified conservative treatment protocol, which included initial hospitalization with rigorous bed rest followed by a rehabilitation program with Jewett brace for osteoporotic vertebral fractures (OVFs) in the elderly patients with a 24-week follow-up.

METHODS

Between April 2012 and Mach 2015, one hundred fifty-four patients met the eligibility for this study. Radiological findings at the 3-week, 6~8-week, 24-week assessment were evaluated. Among these, 11 patients underwent early surgery within the first 2 weeks after admission and 19 patients lost follow-up. Therefore, 124 patients were assessed at the final follow-up visit.

RESULTS

The average vertebral instability in all the present series was 4.9 ± 4.8° at 3-week, 2.9 ± 3.5° at 6~8-week, and 1.8 ± 3.0° at 24-week follow-up visit. Delayed union was observed in 16 patients on the 24-week follow-up visit. Therefore, the present conservative treatment protocol resulted in bony union in 98 out of 124 patients (79.0%, per protocol set analysis) and 98 out of 154 patients including drop-out (63.6%, intention-to-treat analysis). There was no severe adverse event related to initial bed rest. The vertebral instability at 3-week assessment was significantly higher in the delayed union group when compared with that in the union group. Univariate analyses followed by multivariate logistic regression analysis revealed that T2-weighted image of confined high intensity on MRI and having more than 5° of vertebral instability on dynamic X-ray at 3-week assessment are the independent risk factors for delayed union of conservative treatment in the present series.

CONCLUSIONS

Our results showed that initial hospitalization with rigorous bed rest followed by a rehabilitation program using a Jewett brace was safe and feasible. Therefore, the present conservative treatment protocol can be one of the acceptable treatment options in managing OVF patients.

Alendronate promotes osteoblast differentiation and bone formation in ovariectomy-induced osteoporosis through interferon-β/signal transducer and activator of transcription 1 pathway

Alendronate is commonly used for the treatment of postmenopausal osteoporosis; however, the underlying pathological molecular mechanisms of its action remain unclear. In the present study, the alendronate-treated signaling pathway in bone metabolism in rats with ovariectomy induced by osteoporosis was investigated. Rats with osteoporosis were orally administered alendronate or phosphate-buffered saline (control). In addition, the interferon-β (IFN-β)/signal transducer and activator of transcription 1 (STAT1) signaling pathway was investigated in osteoblasts following treatment with alendronate in vitro and in vivo. During the differentiation period, IFN-β (100 ng/ml) was used to treat the osteoblast cells, and the activity, viability and bone metabolism-associated gene expression levels (STAT1, p-STAT1, Fra1, TRAF6 and SOCS1) were analyzed in osteoblast cells. Histopathological changes were used to evaluate osteoblasts, osteoclasts, inflammatory phase of bone healing and osteonecrotic areas. The results demonstrated that alendronate significantly inhibited the activity of osteoporotic osteoclasts by stimulating expression of IFN-β, as well as markedly improved the viability and activity of osteoblasts compared with the control group. In addition, alendronate increased the expression and phosphorylation levels of STAT1 in osteoclasts, enhanced osteoblast differentiation, upregulated the expression levels of alkaline phosphatase and osteocalcin, and increased the expression of osteoblast differentiation-associated genes (osteocalcin, osterix and Runx2). Inhibition of IFN-β expression canceled the benefits of alendronate-mediated osteoblast differentiation. Notably, alendronate enhanced bone formation in rats with osteoporosis induced by ovariectomy. In conclusion, these findings suggest that alendronate can regulate osteoblast differentiation and bone formation in rats with osteoporosis induced by ovariectomy through upregulation of IFN-β/STAT1 signaling pathway.

Denosumab and alendronate treatment in patients with back pain due to fresh osteoporotic vertebral fractures

INTRODUCTION

Denosumab specifically inhibits the receptor activator for nuclear factor-kappa B ligand (RANKL), and prevents osteoporotic fractures. Several reports have analyzed the effects of denosumab and alendronate alone on bone mineral density (BMD) or reduction of fracture risk. The objective of this study was to analyze the effects of antiresorptive osteoporosis pharmacotherapy on pain relief in patients with fresh vertebral fracture.

METHODS

This retrospective, single-center study included 80 patients (10 males, 70 females) with fresh osteoporotic vertebral fractures treated using denosumab at a dose of 60 mg subcutaneously every 6 months (40 patients) or alendronate at a dose of 35 mg orally every week (40 patients) for 6 months in our hospital. The mean age of subjects was 77 years (range, 55-92 years). The primary outcome was duration of back pain. Secondary outcomes included changes in BMD, serum type 1 collagen cross-linked N-telopeptide (NTX), and serum N-terminal propeptide of type 1 collagen (P1NP) from baseline to 6 months. Pain catastrophizing due to back pain was assessed using the Pain Catastrophizing Scale (PCS). The incidences of further vertebral fracture and adverse events were also assessed.

RESULTS

Pain relief was obtained at a mean of 3.3 weeks with denosumab and 5.4 weeks with alendronate. Pain relief was achieved significantly earlier with denosumab than with alendronate. At 6 months, change in BMD was higher with denosumab (6.1%) than with alendronate (0.8%). No significant differences in changes in NTX and P1NP were observed between groups. Scores for PCS were significantly lower for denosumab than for alendronate. The incidence of further vertebral fractures was 5% with denosumab and 10% with alendronate. Adverse event rates were similar between groups.

CONCLUSIONS

Denosumab enabled earlier pain relief than alendronate and avoided catastrophizing in patients with osteoporotic vertebral fractures after 6 months of treatment.

Diagnosis and Management of Cirrhosis-Related Osteoporosis

Management of cirrhosis complications has greatly improved, increasing survival and quality of life of the patients. Despite that, some of these complications are still overlooked and scarcely treated, particularly those that are not related to the liver. This is the case of osteoporosis, the only cirrhosis complication that is not solved after liver transplantation, because bone loss often increases after immunosuppressant therapy. In this review, the definitions of bone conditions in cirrhotic patients are analyzed, focusing on the more common ones and on those that have the largest impact on this population. Risk factors, physiopathology, diagnosis, screening strategies, and treatment of osteoporosis in cirrhotic patients are discussed, presenting the more striking data on this issue. Therapies used for particular conditions, such as primary biliary cirrhosis and liver transplantation, are also presented.

Effect of Brace to Osteoporotic Vertebral Fracture: a Meta-Analysis

Brace is one of the most commonly used interventions to manage osteoporotic vertebral fracture. However, its authentic effectiveness remains unclear. The aim of this study was to investigate the efficacy of brace in patients with osteoporotic vertebral fractures. We conducted a literature review and meta-analysis following the guideline and handbook of the Cochrane collaboration. Ten published articles were included in this study and data from 4 randomized controlled trials were analyzed. Low quality evidence proved using Spinomed brace could bring large and significant beneficial effect to patients with sub-acute osteoporotic vertebral fractures. Very low quality evidence proved no significant difference between Spinomed orthosis, rigid brace and soft brace when they were used in patients with acute fractures. Therefore, it might be applicable to recommend middle term use of Spinomed orthosis to patients with subacute fracture. In addition, this study emphasized the need for high quality randomized controlled trials.
