Abstract
BACKGROUND In epileptic patients with motor disability, it's difficult to disentangle the effects of antiepileptic drugs (AEDs) on bone health from those provoked by impaired mobility. The aim of this study was to evaluate the effects of AEDs on bone mineral status by phalangeal quantitative ultrasound (QUS), a no-radiation and non-invasive method, in pediatric patients with motor impairment and epilepsy. METHODS We enrolled 56 patients (31 females, 25 males) with epilepsy and motor impairment and 24 children with only motor disability (13 females, 11 males). Patients were stratified by Gross Motor Function Classification System Scale (GMFCS) in 4 groups: group A1 with epilepsy and mild motor impairment (GMFCS levels I-II), group A2 with only mild motor impairment, group B1 with epilepsy and severe motor impairment (GMFCS levels III-V), group B2 with only severe motor impairment. The bone mineral status was evaluated by phalangeal QUS and amplitude-dependent speed of sound (AD-SoS) Z-score was calculated for each patient. RESULTS The four groups showed no significant differences in age, gender and 25-hydroxyvitamin D levels. The group B1 had a statistically lower amplitude-dependent speed of sound Z-score as compared to group A2 (P<0.05). The multivariate analysis of independent factors revealed a significant correlation between amplitude-dependent speed of sound Z-score and Gross Motor Function Classification System levels (P=0.004). The mean Z-score value decreased by 0.53, increasing the motor impairment. CONCLUSIONS The bone mineral status measured as AD-SoS strongly correlates with severity of motor disability evaluated by GMFCS as compared to antiepileptic therapy and 25-hydroxyvitamin D levels.

Abstract
BACKGROUND Long-term use of antiseizure drugs is associated with a low bone mineral density (BMD) and an increased fracture risk. The literature regarding institutionalised children on chronic antiseizure drugs is limited. Therefore, the aim of this cross-sectional study is to evaluate the prevalence of low BMD and the history of fractures in institutionalised children with epilepsy and intellectual disability (ID). METHODS A dual-energy X-ray absorptiometry of lumbar spine (L1-L4) and hip was performed in 24 children, residing in a long-stay care facility in the Netherlands. Additionally, serum concentrations of albumin, calcium and 25-hydroxyvitamin D were determined. Data on fractures were retrospectively extracted from the medical files. RESULTS Ages of the children (14 male and 10 female) ranged from 5 to 17 years with a mean age of 13.0 (±3.2). The criteria of the International Society for Clinical Densitometry (ISCD) were used for classification of bone mineral disorders. Eight (33.3%) children had a normal BMD (Z-score > - 2.0). Of the 16 children with a low BMD (Z-score ≤ - 2.0), three were diagnosed as osteoporotic, based on their fracture history. Ten children (41.7%) were reported to have at least one fracture in their medical history. Serum concentrations of albumin-corrected calcium (2.28-2.50 mmol/L) and (supplemented) vitamin D (16-137 nmol/L) were within the normal range. CONCLUSIONS This study demonstrated that 67% of institutionalised children with epilepsy and ID had low BMD and 42% had a history of at least one fracture, despite supplementation of calcium and vitamin D in accordance with the Dutch guidelines.

Measurement of Bone Mineral Density in Children with Cerebral Palsy from an Ethical Issue to a Diagnostic Necessity. BIOMED RESEARCH INTERNATIONAL 2020; 2020:7282946. [PMID: 33015177 PMCID: PMC7525307 DOI: 10.1155/2020/7282946] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/14/2020] [Revised: 08/28/2020] [Accepted: 09/08/2020] [Indexed: 11/29/2022]
Abstract
Introduction Due to concerns about cumulative radiation exposure in the pediatric population, it is not standard practice to perform dual-energy X-ray absorptiometry (DXA) analysis in the diagnostic process of musculoskeletal disorders, such as cerebral palsy (CP). This study aimed to evaluate the bone mineral density (BMD) in children with CP and the ethical justification of applying DXA analysis in these children. Material and Methods. In this monocentric retrospective analysis, data were collected from children and adolescents with CP who were treated for a primary illness for three years. A clinical examination, which included a DXA analysis, recommended by the multidisciplinary team, was performed. After applying inclusion and exclusion criteria, 60 scans remained for statistical analysis. BMD and Z-scores for the lumbar spine (LS), and hip right and left femoral neck (RFN and LFN, respectively), and total hip (TH) were recorded. Results The average age of children with CP when DXA analysis was first performed was about 7 years. The BMD (mean ± SD) at LS (LS-BMD) of all patients was 0.612 ± 0.12, at RFN 0.555 ± 0.11, at LFN 0.572 ± 0.1, and at TH (TH-BMD) 0.581 ± 0.13. The values of the Z-score (mean ± SD) at LS of all patients were −2.5 ± 0.22, at RFN −2.2 ± 0.21, at LFN -2.25 (SD = 0.2), and at TH -2.3 (SD = 0.23). There was no statistical significance between age and gender; however, BMI, walking ability, fracture history, and pattern of CP had a significant impact on BMD and Z-score values of these children. Conclusion The results of our study clearly indicate that children with CP have a higher risk of low BMD, osteoporosis, and bone fractures, which makes it ethically justifiable to perform the DXA analysis in these children.

Abstract
PURPOSE Numerous studies have shown that the risk of fracture is increased by long-term antiepileptic drugs (AEDs). Valproic acid (VPA) is one of the most commonly used AEDs. In this meta-analysis, we aimed to assess the effects of VPA on bone mineral density (BMD) and bone metabolism. METHODS PubMed, Embase, Cochrane and Web of Science databases were searched from inception to January 2019 for articles focusing on the effects of VPA on BMD and bone metabolism in adults or children. A meta-analysis was performed using RevMan 5. 3 software. RESULTS 18 studies were included in the meta-analysis. The BMD of lumber spine (MD= -0.06, 95%CI: -0.09 to -0.03, P < 0.0001) and femoral neck (MD= -0.05, 95% CI= -0.08 to -0.01, P = 0.02) was markedly decreased in the VPA group compared to healthy controls. Serum bone-specific alkaline phosphatase (BALP) level (SMD = 0.85, 95% CI: 0.30-1.40, P = 0.002) was notably increased in the VPA group compared to healthy groups. In the child group, the serum parathyroid hormone (PTH) level was higher than in healthy groups (SMD= -0.22, 95% CI: -0.40 to -0.04, P = 0.02); besides, the serum 25-hydroxy vitamin D3 (25(OH)D3) level was decreased (SMD= -0.22, 95% CI: -0.40 to -0.04, P = 0.02), while no significant alteration of these parameters was noted in the adult VPA group (P ≥ 0.05). CONCLUSIONS VPA may reduce the BMD of lumbar spine and femoral neck in patients with epilepsy while increasing the serum BALP level. Serum PTH level are increased and serum 25(OH)D3 level decreased in children with epilepsy treated with VPA. These parameters were unaltered in adults.

Reasonable adjustments to provide equitable and inclusive assessment, screening and treatment of osteoporosis for adults with intellectual disabilities: A feasibility study. JOURNAL OF APPLIED RESEARCH IN INTELLECTUAL DISABILITIES 2018; 32:300-312.

Abstract
BACKGROUND People with intellectual disabilities are a high risk population for developing osteoporosis and fragility fractures, yet they experience barriers to accessing dual-energy x-ray absorptiometry (DXA) bone mineral density (BMD) screening and fracture assessment. Reasonable adjustments are a statutory requirement in the UK, but there is a paucity of evidence-based examples to assist their identification, implementation and evaluation. METHOD Thirty adults with intellectual disabilities underwent DXA BMD screening and fracture risk assessment. Reasonable adjustments were identified and implemented. RESULTS The presence of osteopenia or osteoporosis was detected in 23 out of 29 (79%) participants. Osteoporosis professionals report that 17 of 18 reasonable adjustments identified and implemented are both important and easy to implement. CONCLUSION Adults across all levels of intellectual disabilities can complete DXA BMD screening with reasonable adjustments. Widely implementing these reasonable adjustments would contribute to reducing inequalities in health care for adults with intellectual disabilities.

Abstract
UNLABELLED This study demonstrated the relationship of low bone mineral density (BMD) with the degree of motor impairment, method of feeding, anthropometric indicators, and malnutrition in children with quadriplegic cerebral palsy (CP). The control of these factors could optimize adequate bone mineralization, avoid the risk of osteoporosis, and would improve the quality of life. PURPOSE The purpose of the study is to explore the relationship between low BMD and nutritional status in children with quadriplegic CP. METHODOLOGY A cross-sectional analytical study included 59 participants aged 6 to 18 years with quadriplegic CP. Weight and height were obtained with alternative measurements, and weight/age, height/age, and BMI/age indexes were estimated. The BMD measurement obtained from the lumbar spine was expressed in grams per square centimeter and Z score (Z). Unpaired Student's t tests, chi-square tests, odds ratios, Pearson's correlations, and linear regressions were performed. RESULTS The mean of BMD Z score was lower in adolescents than in school-aged children (p = 0.002). Patients with low BMD were at the most affected levels of the Gross Motor Function Classification System (GMFCS). Participants at level V of the GMFCS were more likely to have low BMD than levels III and IV [odds ratio (OR) = 5.8 (confidence interval [CI] 95% 1.4, 24.8), p = 0.010]. There was a higher probability of low BMD in tube-feeding patients [OR = 8.6 (CI 95% 1.0, 73.4), p = 0.023]. The probability of low BMD was higher in malnourished children with weight/age and BMI indices [OR = 11.4 (1.3, 94), p = 0.009] and [OR = 9.4 (CI 95% 1.1, 79.7), p = 0.017], respectively. CONCLUSION There was a significant relationship between low BMD, degree of motor impairment, method of feeding, and malnutrition. Optimizing these factors could reduce the risk of osteopenia and osteoporosis and attain a significant improvement of quality of life in children with quadriplegic CP.

Abstract
Multiple sulfatase deficiency (MSD) is an ultra-rare neurodegenerative disorder that results in defective sulfatase post-translational modification. Sulfatases in the body are activated by a unique protein, formylglycine-generating enzyme (FGE) that is encoded by SUMF1. When FGE is absent or insufficient, all 17 known human sulfatases are affected, including the enzymes associated with metachromatic leukodystrophy (MLD), several mucopolysaccharidoses (MPS II, IIIA, IIID, IVA, VI), chondrodysplasia punctata, and X-linked ichthyosis. As such, individuals demonstrate a complex and severe clinical phenotype that has not been fully characterized to date. In this report, we describe two individuals with distinct clinical presentations of MSD. Also, we detail a comprehensive systems-based approach to the management of individuals with MSD, from the initial diagnostic evaluation to unique multisystem issues and potential management options. As there have been no natural history studies to date, the recommendations within this report are based on published studies and consensus opinion and underscore the need for future research on evidence-based outcomes to improve management of children with MSD.

Abstract
Cerebral palsy (CP), a common pediatric movement disorder, causes the most severe physical disability in children. Early diagnosis in high-risk infants is critical for early intervention and possible early recovery. In recent years, multivariate analytic and machine learning (ML) approaches have been increasingly used in CP research. This paper aims to identify such multivariate studies and provide an overview of this relatively young field. Studies reviewed in this paper have demonstrated that multivariate analytic methods are useful in identification of risk factors, detection of CP, movement assessment for CP prediction, and outcome assessment, and ML approaches have made it possible to automatically identify movement impairments in high-risk infants. In addition, outcome predictors for surgical treatments have been identified by multivariate outcome studies. To make the multivariate and ML approaches useful in clinical settings, further research with large samples is needed to verify and improve these multivariate methods in risk factor identification, CP detection, movement assessment, and outcome evaluation or prediction. As multivariate analysis, ML and data processing technologies advance in the era of Big Data of this century, it is expected that multivariate analysis and ML will play a bigger role in improving the diagnosis and treatment of CP to reduce mortality and morbidity rates, and enhance patient care for children with CP.

Abstract
Leukodystrophies are a broad class of genetic disorders that result in disruption or destruction of central myelination. Although the mechanisms underlying these disorders are heterogeneous, there are many common symptoms that affect patients irrespective of the genetic diagnosis. The comfort and quality of life of these children is a primary goal that can complement efforts directed at curative therapies. Contained within this report is a systems-based approach to management of complications that result from leukodystrophies. We discuss the initial evaluation, identification of common medical issues, and management options to establish a comprehensive, standardized care approach. We will also address clinical topics relevant to select leukodystrophies, such as gallbladder pathology and adrenal insufficiency. The recommendations within this review rely on existing studies and consensus opinions and underscore the need for future research on evidence-based outcomes to better treat the manifestations of this unique set of genetic disorders.

Abstract
PURPOSE We aimed to evaluate the relationship between bone mineral density (BMD) disorders and possible risk factors in patients with epilepsy only (EO), cerebral palsy only (CPO), and cerebral palsy-epilepsy (CP + E). METHODS A total of 122 patients [EO (n = 54), CPO (n = 30), CP + E (n = 38)] and 30 healthy children were evaluated. BMD was only measured in patient groups, not in control subjects. BMD of lumbar vertebrae was determined by dual energy X-ray absorptiometry (DXA). An abnormal BMD was defined as low or low normal BMD. RESULTS Low BMD rate in EO, CPO, and CP + E group was 3.7, 50, and 39.5 %, respectively. Abnormal BMD values were significantly related to inadequate dietary Ca intake (p = 0.017), severe intellectual disability (p < 0.001), and immobility (p = 0.018). In multivariate regression analysis, the risk of abnormal BMD was higher (3.9-fold) in patients not able to walk independently than the others (p = 0.029). However, serum Ca-Vitamin D levels, insufficient exposure to sunlight, low BMI, and use of AED were not correlated with abnormal BMD. CONCLUSION Abnormal BMD is a common problem in patients with CP and CP + E. Abnormal BMD was related to the severity of CP, but not to vitamin D levels or AED treatment.

Abstract
INTRODUCTION Diminished bone mineral density and delayed skeletal maturation are common in children with spastic quadriplegia. AIM The purpose of our study was to evaluate the Bone Mineral Density (BMD) of children with moderate to severe spastic quadriplegia and its relationship with other variables like nutrition and growth. MATERIALS AND METHODS This was a hospital based, cross- sectional, case-control study. Forty-two (28 males, 14 females) children with spastic quadriplegia and 42 (24 males, 18 females) healthy children were included in the study. BMD of cases and control were measured by Dual Energy X-ray Absorptiometry (DEXA). Radiographs of left hand and wrist of cases and controls were taken and bone age was determined. RESULTS BMD values of upper extremity, lower extremity, thoraco-lumbar spine and pelvis in cases were lower than those of controls (p <0.0001). In children with non severe malnutrition, 75% of the cases had lower bone age than chronological age, whereas all cases with severe malnutrition had lower bone age than chronological age. Step wise regression analysis showed that nutritional status independently contributed to lower BMD values but the BMD values did not correlate significantly with the use of anticonvulsant drugs and presence of physical therapy. CONCLUSION Decreased BMD and delayed bone age is prevalent in children with spastic quadriplegia and nutritional status is an important contributing factor.

Abstract
Data from cross-sectional and prospective studies revealed that patients with epilepsy and on long-term treatment with antiepileptic drugs (AEDs) are at increased risk for metabolic bone diseases. Bone diseases were reported in about 50% of patients on AEDs. Low bone mineral density, osteopenia/osteoporosis, osteomalacia, rickets, altered concentration of bone turnover markers and fractures were reported with phenobarbital, phenytoin, carbamazepine, valproate, oxcarbazepine and lamotrigine. The mechanisms for AEDs-induced bone diseases are heterogeneous and include hypovitaminosis D, hypocalcemia and direct acceleration of bone loss and/or reduction of bone formation. This article reviews the evidence, predictors and mechanisms of AEDs-induced bone abnormalities and its clinical implications. For patients on AEDs, regular monitoring of bone health is recommended. Prophylactic administration of calcium and vitamin D is recommended for all patients. Treatment doses of calcium and vitamin D and even anti-resorptive drug therapy are reserved for patients at high risk of pathological fracture.

Abstract
INTRODUCTION Children with cerebral palsy (CP) have an increased risk of vitamin D (VD) deficiency. Although there are many studies on VD and CP, there is limited information about VD supplementation in these patients. OBJECTIVE To evaluate the effect of supplementation with a single dose of VD on the plasma concentrations of 25-hydroxy-vitamin-D (25OHD) in children with CP. PATIENTS AND METHOD Prospective-randomised-controlled-trial, including 30 Chilean children (19 males) with CP, median age 9.9 years (6.2-13.5). Clinical and biochemical variables including 25OHD, were recorded (time 0 and 8 weeks). Patients were allocated to the supplemented (S) group receiving 100,000 IU oral D3 at baseline, and compared with the placebo (P) group. RESULTS Among clinical features are highlighted: gastrostomy (60%), underweight (30%), bed-ridden (93.3%), antiepileptic drugs (70%), and 43.3% used VD metabolism inducing antiepileptics. Baseline biochemical measurements were normal. The 25OHD was insufficient in 4/30 and deficient in 6/30. 25OHD levels were not associated with the variables studied. Eight patients completed the study in the S group, and 10 in P group. The placebo and supplementation groups had no significant difference in baseline variables. Serum calcium, phosphate, and alkaline phosphatase levels at 8 weeks were normal in both groups, with no statistically significant differences. 25OHD in the P group was normal in 6/10, and insufficient+deficient in 4/10, and the S group was normal in all (8/8) (exact Fisher test P=.07). CONCLUSIONS A single dose of 100,000 IU VD could normalise the concentrations of 25OHD after 8 weeks of supplementation in Children with CP, but more studies are required to confirm these results.

Abstract
BACKGROUND Bone health may be impaired in children with epilepsy. OBJECTIVES Our objective was to characterize bone mineral density (BMD) and bone growth in children receiving antiepileptic drugs (AEDs) and to assess the effects of co-morbidity, vitamin D deficiency, and type of drugs used. DATA SOURCES Data were sourced from PubMed, Embase, and Web of Science. ELIGIBILITY CRITERIA Cross-sectional, cohort, case-control, or randomized controlled trials reporting BMD or parameters of bone growth. PARTICIPANTS Children with epilepsy compared with controls. INTERVENTIONS AEDS or ketogenic diet. STUDY APPRAISAL The studies were evaluated by one author. SYNTHESIS METHODS Studies were categorized as reporting reduced BMD or not at any skeletal site as outcome. A logistic regression was performed for age, percent boys, study design, type of AED, co-morbidity or not, and signs of vitamin D deficiency/osteomalacia or not. RESULTS Carbamazepine and valproate were analyzed as monotherapy in 11 studies, and for both drugs a limited decrease in BMD seemed present. For oxcarbazepine, levetiracetam, phenytoin, phenobarbital, and topiramate, only one study with monotherapy was found for each drug, none of which reported decreased bone density. Polytherapy with AEDs seemed to be associated with a larger decrease in bone density than was monotherapy. Although few studies were available on bone growth, these did indicate that bone growth may be impaired among users of AEDs. Ketogenic diet may be associated with decreased bone density. The main determinant of normal BMD was absence of vitamin D deficiency/osteomalacia. LIMITATIONS The studies differed in skeletal sites studied and most were cross-sectional. No head-to-head comparisons of AEDs were performed. Children treated with polytherapy or ketogenic diet may have more complicated and severe disease than those treated with monotherapy. The underlying cause of epilepsy and vitamin D deficiency may contribute to impaired bone growth and density. CONCLUSIONS Reduced bone density, impaired bone growth, and vitamin D deficiency may be seen in children treated with drugs against epilepsy. IMPLICATIONS Measures to correct vitamin D deficiency, calcium intake should be taken.

Abstract
OBJECTIVE To elucidate the effects of antiepileptic drugs (AEDs) on bone health status of ambulatory epileptic children. METHODS A total of 120 epileptic children aged 2-15 y were enrolled in three groups. The first group was on therapy with carbamazepine, phenobarbital or primidone. The second was treated with valproic acid and the third group was untreated. Serum calcium, phosphorous, total alkaline phosphatase, and parathyroid hormone levels were compared between groups. Bone mineral density tests were also performed at four sites of the lumbar spine and three sites of femoral neck and results were compared between the groups. RESULTS Of all enrolled subjects, 67 patients (55.8 %) were vitamin D deficient. The three groups were not significantly different in terms of vitamin D, calcium, phosphorus, total alkaline phosphatase, and parathyroid hormone levels. While patients in first group had lower Z-score of femoral neck and lumbar spine compared to those on valproic acid, these values were also significantly different than that of the third group. CONCLUSIONS It can be concluded that both enzyme-inducing AEDs and non enzyme-inducing AEDs decrease bone mineral density (BMD). Also alkaline phosphatase (ALP) is affected in ambulatory epileptic children on enzyme-inducing AEDs. Nevertheless, valproic acid (a non-enzyme-inducing agent) does not have the mentioned side effects.

Abstract
The purpose of this study was to investigate the prevalence of and contributing factors to osteopenia and osteoporosis among people with intellectual disabilities (ID) or/and developmental disabilities (DD) residing in a disability institution in Taiwan. The present study was conducted at one disability institution in Taiwan and recruited 184 institutionalized residents with ID and/or DD (115 men and 69 women aged 18-72 years) for analysis. For all residents with ID and/or DD, information was obtained about their age, gender, level of ID, BMI, and bone mineral density (BMD). BMD is a measurement of calcium levels in bones that can estimate the risk of osteoporosis and bone fractures. Bone tests were divided into three outcome categories based on their calcaneal BMD T-scores: Normal BMD, a T-score≧-1; Osteopenia, -2.5≦T-score<-1; and Osteoporosis, a T-score<-2.5. The results revealed that 46.2% of cases were normal and that 27.7% and 26.1% of cases had osteopenia and osteoporosis, respectively. Multiple logistic regression analyses found that male gender (OR=2.482, 95% CI=1.04-5.93, p<0.05), age≧40 years (OR=3.051, 95% CI=1.07-8.69, p<0.05) and being overweight/obese (OR=0.395, 95% CI=0.17-0.93, p<0.05) were more likely to be associated with osteoporosis. Another model indicated that males (OR=2.169, 95% CI=1.12-4.19, p<0.05) and those aged≧40 years (OR=3.026, 95% CI=1.32-7, p<0.01) tended to have an increased risk for osteopenia and osteoporosis. To improve the bone quality of individuals with ID or/and DD and to decrease the occurrence of osteopenia and osteoporosis, this study highlights that we should pay much attention to the potential risk factors for bone quality in these vulnerable populations.

Abstract
The consequences of disability span almost all aspects of life, for families and for an affected individual. Endocrine aspects of disability cover disorders of hypothalamic pituitary dysfunction, bone health, puberty, fertility, sexual function and contraceptive needs. Adequate endocrine assessment for a child with a disability requires extensive and sensitive history to address social issues, general nutrition, vitamin D status, specific hypothalamic pituitary problems, together with parental concerns regarding puberty and contraception. Bone health assessment includes history of minimal trauma fracture, need for intervention or fitness for surgery. Strategic interventions to improve outcome include management of puberty, vitamin D status, biomechanical stimulation with vibration and standing and possible consideration for bisphosphonate in special circumstances. Both early and late puberty cause major family concerns. The paediatrician must be aware of a range of management options to improve outcomes for the child and family.

Abstract
The aim of this Task Force was to review the use of dual-energy X-ray absorptiometry (DXA) in children and adolescents with underlying chronic diseases that pose risk factors for compromised bone health, such as inflammation, glucocorticoid therapy, or decreased mobility. The Task Force systematically analyzed more than 270 studies, with an emphasis on those published in the interval since the original 2007 Position Statements. Important developments over this period included prospective cohort studies demonstrating that DXA measures of areal bone mineral density (aBMD) predicted incident fractures and the development of robust reference data and strategies to adjust for bone size in children with growth impairment. In this report, we summarize the current literature on the relationship between DXA-based aBMD and both fracture (vertebral and non-vertebral) outcomes and non-fracture risk factors (e.g., disease characteristics, ambulatory status, and glucocorticoid exposure) in children with chronic illnesses. Most publications described the aBMD profile of children with underlying diseases, as well as the cross-sectional or longitudinal relationship between aBMD and clinically relevant non-fracture outcomes. Studies that addressed the relationship between aBMD and prevalent or incident fractures in children with chronic illnesses are now emerging. In view of these updated data, this report provides guidelines for the use of DXA-based aBMD in this setting. The initial recommendation that DXA is part of a comprehensive skeletal healthy assessment in patients with increased risk of fracture is unchanged. Although the prior guidelines recommended DXA assessment in children with chronic diseases at the time of clinical presentation with ongoing monitoring, this revised Position Statement focuses on the performance of DXA when the patient may benefit from interventions to decrease their elevated risk of a clinically significant fracture and when the DXA results will influence that management.
