[PMID: 38579925 DOI: 10.1016/j.bone.2024.117093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Revised: 03/29/2024] [Accepted: 04/02/2024] [Indexed: 04/07/2024]
Abstract
BACKGROUND Clinical concerns about preventing and managing fractures after spinal cord injury (SCI) have been growing. OBJECTIVE This study investigates the risk of fractures among SCI patients according to the presence of disability, disease severity, and level of injury. METHODS We performed a retrospective cohort study using the Korean National Health Insurance Service (KNHIS 2010-2018) database. We included 5190 SCI patients and 1:3 age- and sex-matched control participants. The primary outcome was fracture, and the cohort was followed until December 31, 2019. RESULTS SCI patients had a higher fracture risk than the matched controls (adjusted hazard ratio [aHR] 1.33, 95 % CI 1.16-1.54). The risk of fracture was higher in the presence of disability (aHR 1.57, 95 % CI 1.19-2.07), especially among patients with severe disability (aHR 1.65, 95 % CI 1.05-2.60). Higher fracture risks were observed among SCI patients regardless of injury level, but statistical significance was found only with cervical-level injury. When we considered site-specific fractures, vertebral (aHR 1.31, 95 % CI 1.04-1.64) and hip fracture risks (aHR 2.04, 95 % CI 1.39-2.98) were both higher among SCI patients than the controls. SCI patients with disability and cervical-level injury showed the highest hip fracture risk (aHR 3.67, 95 % CI 1.90-7.07). CONCLUSIONS Compared with the controls, SCI patients were at higher risk of any fracture, particularly hip fracture, especially those with disability and cervical-level injury. Clinicians should be aware of the fracture risk among SCI patients to provide proper management.

Abstract
Objectives To develop SCI-FX, a risk score to estimate 5-year lower extremity fragility fracture risk among patients living with chronic spinal cord injury (cSCI). Methods Adults with traumatic cSCI (n = 90) participated in a 2-year prospective longitudinal cohort study describing bone mineral density (BMD) change and fracture incidence conducted at the Lyndhurst Centre (University Health Network), University of Waterloo, and Physical Disability Rehabilitation Institute of Québec City. Prior publication and clinical intuition were used to identify fragility fracture risk factors including prior fragility fracture, years post-injury, motor complete injury (AIS A/B), benzodiazepine use, opioid use, and parental osteoporosis. We conducted bivariate analyses to identify variables associated with fracture. Multiple logistic regressions were performed using fragility fracture incidence as the dependent variable and all variables from the univariate analyses with a highly liberal p value at 0.2. Using the odds ratios (ORs) from the multiple logistic regression model, a point system for fragility fracture risk score was developed, and the odds of fracture for each point was estimated. Results All initial variables, with the exception of benzodiazepine exposure, were included in the final model. Conclusion We identified a simple preliminary model for clinicians to estimate 5-year fracture risk among patients with cSCI based on their total score.

Abstract
BACKGROUND The prevention of lower extremity fractures and fracture-related morbidity and mortality is a critical component of health services for adults living with chronic spinal cord injury (SCI). METHODS Established best practices and guideline recommendations are articulated in recent international consensus documents from the International Society of Clinical Densitometry, the Paralyzed Veterans of America Consortium for Spinal Cord Medicine and the Orthopedic Trauma Association. RESULTS This review is a synthesis of the aforementioned consensus documents, which highlight the pathophysiology of lower extremity bone mineral density (BMD) decline after acute SCI. The role and actions treating clinicians should take to screen, diagnose and initiate the appropriate treatment of established low bone mass/osteoporosis of the hip, distal femur or proximal tibia regions associated with moderate or high fracture risk or diagnose and manage a lower extremity fracture among adults with chronic SCI are articulated. Guidance regarding the prescription of dietary calcium, vitamin D supplements, rehabilitation interventions (passive standing, functional electrical stimulation (FES) or neuromuscular electrical stimulation (NMES)) to modify bone mass and/or anti-resorptive drug therapy (Alendronate, Denosumab, or Zoledronic Acid) is provided. In the event of lower extremity fracture, the need for timely orthopedic consultation for fracture diagnosis and interprofessional care following definitive fracture management to prevent health complications (venous thromboembolism, pressure injury, and autonomic dysreflexia) and rehabilitation interventions to return the individual to his/her pre-fracture functional abilities is emphasized. CONCLUSIONS Interprofessional care teams should use recent consensus publications to drive sustained practice change to mitigate fracture incidence and fracture-related morbidity and mortality among adults with chronic SCI.

Loss of lower extremity bone mineral density 1 year after denosumab is discontinued in persons with subacute spinal cord injury. Osteoporos Int 2023; 34:741-748. [PMID: 36735054 DOI: 10.1007/s00198-023-06679-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Accepted: 01/17/2023] [Indexed: 02/04/2023]
Abstract
UNLABELLED Twelve months following discontinuation of denosumab, the percent decrease in mean bone mineral density (BMD) values at the hip and knee regions were similar between both the denosumab and placebo groups. These findings emphasize the need for additional trials to understand the effect of continued administration of denosumab after subacute spinal cord injury (SCI) to avoid this demineralization. OBJECTIVE To determine changes in BMD 1 year after denosumab was discontinued in participants with subacute SCI who had drug treatment initiated within 90 days post SCI and continued for 1 year. METHODS Fourteen participants who completed a randomized, double-blinded, placebo-controlled drug trial (parent study: denosumab 60 mg (Prolia, Amgen Inc., n = 8) or placebo (n = 6); administered at baseline, 6, and 12 months) were followed 12 months after the 18 months from baseline primary end point was completed. The BMD of skeletal regions below the SCI at higher risk of fracture was measured [total hip, distal femur epiphysis (DFE), distal femur metaphysis (DFM), and proximal tibia epiphysis (PTE)] by dual energy X-ray absorptiometry. RESULTS The percent decreases in mean BMD values at all regions of the hip and knee from 18 to 30 months were similar in both the denosumab and placebo groups. However, at 30 months, the absolute values for mean BMD remained significantly higher in the drug treatment than that of the placebo group at the DFM (p = 0.03), DFE (p = 0.04), and PTE (p = 0.05). CONCLUSIONS In persons with SCI who initiated denosumab treatment during the subacute injury phase and maintained treatment for 1 year, the discontinuation of drug resulted in percent loss of mean BMD similar to that of the placebo group, with absolute mean BMD values at the knee regions at the 12-month follow-up visit significantly higher in the drug treatment than those in the placebo group. These data underscore the need to study continued administration of denosumab after subacute SCI to avoid marked demineralization in the sublesional skeleton upon discontinuation of this agent.

Abstract
OBJECTIVE Bone loss is not to be underestimated in people with acute spinal cord injury (SCI). Bisphosphonates can inhibit the bone resorption of osteoclast. To study whether the early application of bisphosphonates can alleviate bone loss after acute SCI, we included 7 randomized controlled trials for meta-analysis. METHODS Seven randomized controlled trials were found in literature databases. The percentage change in bone mineral density (BMD) at different sites were primary outcomes and serum bone turnover markers were secondary outcomes. A random-effects model was selected for meta-analysis. RESULTS There were significant differences in the percentage change in BMD of the lumbar spine, total hip, and femoral neck between the bisphosphonates and control groups, but not in the percentage change in distal femur BMD. Besides, there were no statistically significant differences between the groups in the bone formation marker Procollagen type 1 N propeptide; bisphosphonates were effective in reducing the C-terminal telopeptide at the 6-month follow-up, but not at the 12-month follow-up. Subgroup analysis of the effects of zoledronate showed positive effects on BMD of the lumbar spine, total hip, and femoral neck at the 6-month follow-up and showed positive effects on BMD of the total hip and femoral neck at the 12-month follow-up. CONCLUSIONS Bisphosphonates can effectively alleviate the bone loss of the lumbar spine, total hip, and femoral neck in patients with acute SCI, and early application is advocated.

Abstract
OBJECTIVE To investigate the prevalence and influencing factors of spinal cord injury (SCI)-related osteoporosis and fragility fractures in Thai people with chronic spinal cord injury. DESIGN A cross-sectional, observational study. SETTING Outpatient clinic, Department of Rehabilitation Medicine, Maharaj Nakorn Chiang Mai Hospital. PARTICIPANTS Thais with chronic spinal cord injury (SCI) (duration of injury at least one year). INTERVENTION Not applicable. OUTCOME MEASURES Dual-energy X-ray absorptiometry (DXA) was performed to measure bone mineral density (BMD) at the hip. Analyses were performed to identify risk factors for SCI-related osteoporosis or fragility fracture development. Thai FRAX® score was calculated with and without BMD and compared for each participant. RESULTS Among 64 Thais with chronic SCI, the prevalence of SCI-related osteoporosis was 43.8%. Female sex, non-ambulatory status, and at least 10 years duration of spinal cord injury increased the risk of having SCI-related osteoporosis. The prevalence of fragility fracture was 9.4%. Female sex, duration of SCI, and being diagnosed with SCI-related osteoporosis increased the risk of having a fragility fracture. Thai FRAX® score without BMD value underestimated the risk of prevalent fracture in 7.8% of participants. CONCLUSIONS SCI-related osteoporosis and fragility fractures are common in Thais with chronic SCI. Our findings emphasize the importance of SCI-related osteoporosis and fragility fracture surveillance in people with chronic SCI regardless of their ethnicity. FRAX® without BMD calculations could underestimate the risk of fragility fracture in people with chronic SCI. Therefore, further studies are needed to develop an SCI-specific fracture-risk assessment tool using risk factors proposed in previous studies and in this study.

Abstract
Objective To investigate the correlation between bone mineral density (BMD) and duration of injury in individuals with spinal cord injury (SCI). Methods Patients with SCI who visited the outpatient department between January 2009 and January 2019 were enrolled. Patients’ most recent dual energy X-ray absorptiometry images were reviewed. According to the 2007 International Society for Clinical Densitometry guidelines, vertebrae with a local structural change were excluded when deriving spine BMD. If one or no vertebra is suitable for evaluation, spine BMD was judged as “improper for assessment”. Correlation analysis was performed between duration from injury and BMD Z-scores of the hip and spine. Results Among 83 individuals with SCI, the spines of 44 were judged as improper for assessment. The correlation analysis showed a significant negative relationship between the duration from injury and femur neck BMD (r=-0.40, p<0.01) and total proximal femur BMD (r=-0.39, p<0.01). However, no significant correlation was found between the duration from injury and spine BMD Z-score. Conclusion The duration of SCI correlated with hip BMD, but not with spine BMD. Further, more than half of the individuals with SCI could not undergo spinal assessment due to local structural changes. Therefore, spine BMD measurement is not an appropriate method for predicting future fracture risk in those with SCI.

Abstract
Spinal cord injury (SCI) results in dramatic changes in body composition, with lean mass decreasing and fat mass increasing in specific regions that have important cardiometabolic implications. Accordingly, the recent Consortium for Spinal Cord Medicine (CSCM) released clinical practice guidelines for cardiometabolic disease (CMD) in SCI recommending the use of compartmental modeling of body composition to determine obesity in adults with SCI. This recommendation is guided by the fact that fat depots impact metabolic health differently, and in SCI adiposity increases around the viscera, skeletal muscle, and bone marrow. The contribution of skeletal muscle atrophy to decreased lean mass is self-evident, but the profound loss of bone is often less appreciated due to methodological considerations. General-population protocols for dual-energy x-ray absorptiometry (DXA) disregard assessment of the sites of greatest bone loss in SCI, but the International Society for Clinical Densitometry (ISCD) recently released an official position on the use of DXA to diagnose skeletal pathology in SCI. In this review, we discuss the recent guidelines regarding the evaluation and monitoring of obesity and bone loss in SCI. Then we consider the possible interactions of obesity and bone, including emerging evidence suggesting the possible influence of metabolic, autonomic, and endocrine function on bone health in SCI.

Reasons for Initiation and Discontinuation of Pharmacological Therapies for Osteoporosis in Veterans with Spinal Cord Injury and Disorders. J Clin Densitom 2021; 24:67-77. [PMID: 31262561 DOI: 10.1016/j.jocd.2019.06.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2019] [Revised: 06/10/2019] [Accepted: 06/11/2019] [Indexed: 01/20/2023]
Abstract
INTRODUCTION Medications for osteoporosis have not been reported to reduce fracture rates in patients with spinal cord injury and disorders (SCI/D), yet these medications are still prescribed. Clinical decision-making underscoring the initiation and discontinuation of osteoporosis medications in SCI/D remains poorly understood. METHODOLOGY Veterans with a SCI/D with at least one prescription for an osteoporosis medication (bisphosphonate, calcitonin, denosumab, raloxifene, and teriparatide) who received healthcare within Veterans Affairs (VA) from 2005 to 2015 were identified using VA administrative databases. A 10% subsample of Veterans was selected for electronic health record review. RESULTS Two hundred and sixty-seven Veterans with 330 prescriptions underwent electronic health record review. Bisphosphonates were the most frequently prescribed medication for osteoporosis (n = 223, 67.6%). Of the 187 Veterans with prescriptions for prevention or treatment of osteoporosis, the primary reason for initiation was Dual Energy X-ray Absorptiometry (DXA) scan with osteopenia or osteoporosis (n = 119, 63.6% of Veterans), primarily at the hip (81.0% of DXAs). The majority (79.0%) of DXAs were "screening tests," with SCI/D being the sole reason for the scan. Fractures (n = 51, 27.3%) and fall risk concerns (n = 29, 15.5%) were other major reasons for initiation. On average, oral bisphosphonates were filled for <3 yr, with medication-related side effects (n = 23, 15.8% of bisphosphonates discontinued), predominately gastrointestinal (n = 17, 73.9% of reported side effects), the most common reason for discontinuation. Drug holidays occurred in 14.3% of 35 oral bisphosphonates used for ≥5 yr. No cases of osteonecrosis of the jaw were found. There was one case of an atypical femoral fracture which could not be confirmed. CONCLUSIONS The decision to initiate pharmacological therapies in SCI/D is primarily based on osteopenia or osteoporosis at the hip by screening DXAs. Gastrointestinal side effects are the major reason for discontinuation of oral bisphosphonates. New therapies for osteoporosis in SCI/D are needed.

Factors influencing providers' decisions on management of bone health in people with spinal cord injury. Spinal Cord 2020; 59:787-795. [PMID: 33239741 DOI: 10.1038/s41393-020-00589-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Revised: 11/04/2020] [Accepted: 11/09/2020] [Indexed: 11/09/2022]
Abstract
STUDY DESIGN Survey. OBJECTIVES Managing osteoporosis in persons with chronic spinal cord injury (SCI) is difficult as little evidence exists regarding effective strategies. We examined the effect of key factors on providers' bone health management decisions in persons with SCI. SETTING USA. METHODS Providers reviewed blocks of 9 hypothetical cases that varied on four factors: osteoporosis, osteopenia, or normal bone mineral density using dual-energy X-ray absorptiometry (DXA); DXA region of interest (lumbar spine, hip, knee), prior lower extremity fracture; and no or limited ambulation. They indicated how likely they would recommend pharmacological management, what treatment(s) they would recommend, and whether they would request another DXA before treatment. RESULTS Eighty-two healthcare providers completed the survey. Treatment recommendations for bisphosphonates and Vitamin D/calcium supplements, respectively, were more likely if there was a prior fracture (OR: 2.65, 95%CI: 1.76-3.99, p < 0.0001; OR: 2.96, 95%CI: 1.40-6.26, p = 0.004) and if a DXA scan found osteopenia (OR: 2.23, 95%CI: 1.41-3.54, p = 0.001; OR: 6.56, 95%CI: 2.71-15.85, p < 0.0001) or osteoporosis (OR: 12.08, 95%CI: 7.09-20.57, p < 0.0001; OR: 4.54, 95%CI: 2.08-9.90, p < 0.0001). Another DXA scan was more likely to be requested if there was a prior fracture (OR: 1.75, 95%CI: 1.10-2.78, p = 0.02) but less likely if the person was nonambulatory (OR: 0.41, 95%: 0.19-0.90, p = 0.03). CONCLUSIONS Prior fracture and DXA findings influenced treatment recommendations for bone health management in SCI. Reliance on lumbar spine scans to determine bone loss and treatment identifies a knowledge gap for which future education is required.

Stiffness and Strength Predictions From Finite Element Models of the Knee are Associated with Lower-Limb Fractures After Spinal Cord Injury. Ann Biomed Eng 2020; 49:769-779. [PMID: 32929557 DOI: 10.1007/s10439-020-02606-w] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Accepted: 09/02/2020] [Indexed: 02/07/2023]
Abstract
Spinal cord injury (SCI) is associated with bone fragility and fractures around the knee. The purpose of this investigation was to validate a computed tomography (CT) based finite element (FE) model of the proximal tibia and distal femur under biaxial loading, and to retrospectively quantify the relationship between model predictions and fracture incidence. Twenty-six cadaveric tibiae and femora (n = 13 each) were loaded to 300 N of compression, then internally rotated until failure. FE predictions of torsional stiffness (K) and strength (Tult) explained 74% (n = 26) and 93% (n = 7) of the variation in experimental measurements, respectively. Univariate analysis and logistic regression were subsequently used to determine if FE predictions and radiographic measurements from CT and dual energy X-ray absorptiometry (DXA) were associated with prevalent lower-limb fracture in 50 individuals with SCI (n = 14 fractures). FE and CT measures, but not DXA, were lower in individuals with fracture. FE predictions of Tult at the tibia demonstrated the highest odds ratio (4.98; p = 0.006) and receiver operating characteristic (0.84; p = 0.008) but did not significantly outperform other metrics. In conclusion, CT-based FE model predictions were associated with prevalent fracture risk after SCI; this technique could be a powerful tool in future clinical research.

The design of a randomized control trial of exoskeletal-assisted walking in the home and community on quality of life in persons with chronic spinal cord injury. Contemp Clin Trials 2020; 96:106102. [PMID: 32800962 DOI: 10.1016/j.cct.2020.106102] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2020] [Revised: 07/27/2020] [Accepted: 08/04/2020] [Indexed: 02/06/2023]
Abstract
There are more than 300,000 estimated cases of spinal cord injury (SCI) in the United States, and approximately 27,000 of these are Veterans. Immobilization from SCI results in adverse secondary medical conditions and reduced quality of life. Veterans with SCI who have completed rehabilitation after injury and are unable to ambulate receive a wheelchair as standard of care. Powered exoskeletons are a technology that offers an alternative form of limited mobility by enabling over-ground walking through an external framework for support and computer-controlled motorized hip and knee joints. Few studies have reported the safety and efficacy for use of these devices in the home and community environments, and none evaluated their impact on patient-centered outcomes through a randomized clinical trial (RCT). Absence of reported RCTs for powered exoskeletons may be due to a range of challenges, including designing, statistically powering, and conducting such a trial within an appropriate experimental framework. An RCT for the study of exoskeletal-assisted walking in the home and community environments also requires the need to address key factors such as: avoiding selection bias, participant recruitment and retention, training, and safety concerns, particularly in the home environment. These points are described here in the context of a national, multisite Department of Veterans Affairs Cooperative Studies Program-sponsored trial. The rationale and methods for the study design were focused on providing a template for future studies that use powered exoskeletons or other strategies for walking and mobility in people with immobilization due to SCI.

Association of Bisphosphonate Therapy With Incident of Lower Extremity Fractures in Persons With Spinal Cord Injuries or Disorders. Arch Phys Med Rehabil 2020; 101:633-641.

Abstract
OBJECTIVE To investigate the association between prescriptions for bisphosphonates; calcium and vitamin D supplements; and receipt of dual-energy x-ray absorptiometry (DXA) screening, and incident fracture risk in men and women with a spinal cord injury (SCI) or disorder (SCID). DESIGN Propensity-matched case-control analyses. SETTING United States Veterans Affairs (VA) facilities. PARTICIPANTS A total of 7989 men and 849 women with an SCID included in VA administrative databases between October 1, 2005 and October 1, 2015 were identified (N=8838). Cases included 267 men and 59 women with a bisphosphonate prescription propensity matched with up to 4 controls. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Incident lower extremity fractures. RESULTS There was no significant association between prescriptions for bisphosphonates and incident lower extremity fractures in men (odds ratio [OR], 1.04; 95% confidence interval [CI], 0.62-1.77) or women (OR, 1.02; 95% CI, 0.28-3.75). In men, similar null associations were seen among those who were adherent to bisphosphonate therapy (OR, 1.25; 95% CI, 0.73-2.16), were concomitant users of vitamin D and calcium and a bisphosphonate (OR, 1.05; 95% CI, 0.57-1.96), had more than 1 fracture on different dates during the study period (OR, 0.13; 95% CI, 0.02-1.16) and in those who had undergone DXA testing prior to the date of the bisphosphonate prescription and incident fracture (OR, 1.26; 95% CI, 0.69-2.32). CONCLUSIONS In men with a traumatic SCI and women with a traumatic SCID, bisphosphonate therapies for osteoporosis do not appear to significantly affect fracture risk. Adequately powered randomized controlled trials are needed to definitively demonstrate efficacy of bisphosphonates for fracture prevention in this population. There is a compelling need to identify new medications to prevent fractures in this high-risk population.

Abstract
Objective: To describe frequency and predictors of use of pharmacological therapies for osteoporosis in persons with a spinal cord injury (SCI).Design: Retrospective cohort study.Setting: United States Veterans Health Administration (VA) national databases.Participants: 11,048 persons with a traumatic SCI who received VA health care between Fiscal Years (FY) 2005-2015. Pharmacy data from VA's Corporate Data Warehouse were used to identify prescriptions for Food and Drug Administration-approved pharmacological treatments for osteoporosis including bisphosphonates, calcitonin, denosumab, raloxifene and teriparatide.Outcome Measures: Demographics, clinical and SCI-related characteristics, receipt of a dual energy x-ray absorptiometry (DXA), and prevalent lower extremity fractures were examined to determine factors related to receiving a pharmacological agent for osteoporosis.Results: 1,041 persons (9.4%) had a prescription for a pharmacological agent for osteoporosis; the majority (n = 964, 93.0%) were bisphosphonates. There was a significant decline in the number of these prescriptions from FY 2005 (13.0%) to FY 2015 (2.2%). In multivariable analysis, age (>50 years) (OR = 1.60, 95% CI 1.31-1.94); female sex (OR = 4.09, 95% CI 2.74-6.09); opioid (OR = 1.24, 95% CI 1.01-1.51) or corticosteroid (OR = 1.92, 95% CI 1.01-1.51) prescriptions; complete injury (OR = 1.26, 95% CI 1.04-1.53); receipt of a DXA scan (OR = 84.03, 95% CI 59.80-118.07) and prevalent fracture (OR = 5.43, 95% CI 4.13-7.15) were positive predictors. Black race (OR = 0.43, 95% CI 0.33-0.57) and obese BMI (OR = 0.59, 95% CI 0.45-0.76) were negative predictors.Conclusions: Prescriptions for osteoporosis medications for persons with a SCI declined in recent years. The strongest predictors for having filled these prescriptions were having had a DXA or a prevalent fracture.

Abstract
Objectives: The primary objective was to review the literature regarding methodologies to assess fracture risk, to prevent and treat osteoporosis and to manage osteoporotic fractures in SCI/D.Study Design: Scoping review.Settings/Participants: Human adult subjects with a SCI/D.Outcome measures: Strategies to identify persons with SCI/D at risk for osteoporotic fractures, nonpharmacological and pharmacological therapies for osteoporosis and management of appendicular fractures.Results: 226 articles were included in the scoping review. Risk of osteoporotic fractures in SCI is predicted by a combination of DXA-defined low BMD plus clinical and demographic characteristics. Screening for secondary causes of osteoporosis, in particular hyperparathyroidism, hyperthyroidism, vitamin D insufficiency and hypogonadism, should be considered. Current antiresorptive therapies for treatment of osteoporosis have limited efficacy. Use of surgery to treat fractures has increased and outcomes are good and comparable to conservative treatment in most cases. A common adverse event following fracture was delayed healing.Conclusions: Most of the research in this area is limited by small sample sizes, weak study designs, and significant variation in populations studied. Future research needs to address cohort definition and study design issues.

Abstract
Spinal cord injury (SCI) causes rapid osteoporosis that is most severe below the level of injury. More than half of those with motor complete SCI will experience an osteoporotic fracture at some point following their injury, with most fractures occurring at the distal femur and proximal tibia. These fractures have devastating consequences, including delayed union or nonunion, cellulitis, skin breakdown, lower extremity amputation, and premature death. Maintaining skeletal integrity and preventing fractures is imperative following SCI to fully benefit from future advances in paralysis cure research and robotic-exoskeletons, brain computer interfaces and other evolving technologies. Clinical care has been previously limited by the lack of consensus derived guidelines or standards regarding dual-energy X-ray absorptiometry-based diagnosis of osteoporosis, fracture risk prediction, or monitoring response to therapies. The International Society of Clinical Densitometry convened a task force to establish Official Positions for bone density assessment by dual-energy X-ray absorptiometry in individuals with SCI of traumatic or nontraumatic etiology. This task force conducted a series of systematic reviews to guide the development of evidence-based position statements that were reviewed by an expert panel at the 2019 Position Development Conference in Kuala Lumpur, Malaysia. The resulting the International Society of Clinical Densitometry Official Positions are intended to inform clinical care and guide the diagnosis of osteoporosis as well as fracture risk management of osteoporosis following SCI.

Abstract
OBJECTIVE The rate of areal bone mineral density (aBMD) loss at the knee (distal femur (DF) and proximal tibia ) and hip (femoral neck (FN) and total hip (TH)) was determined in persons with traumatic spinal cord injury (SCI) who were stratified into subgroups based on time since injury (TSI). DESIGN Cross-sectional retrospective review. SETTING Department of Veterans Affairs Medical Center and Private Rehabilitation Hospital. PARTICIPANTS Data on 105 individuals with SCI (TSI ≤12 months, n = 19; TSI 1-5 years, n = 35; 6-10 years, n = 19; TSI 11-20 years, n = 16; TSI >20 years, n = 15) and 17 able-bodied reference (ABref) controls. INTERVENTIONS NA Main Outcome Measures: The knee and hip aBMD values were obtained by dual energy X-ray absorptiometry (GE Lunar iDXA) using standard clinical software for the proximal femur employed in conjunction with proprietary research orthopedic knee software applications. Young-normal (T-score) and age-matched (Z-scores) standardized scores for the FN and TH were obtained using the combined GE Lunar/National Health and Nutrition Examination Survey (NHANES III) combined reference database. RESULTS When groups were stratified and compared as epochs of TSI, significantly lower mean aBMD and reference scores were observed as TSI increased, despite similar mean ages of participants among the majority of TSI epoch subgroups. Loss in aBMD occurred at the distal femur (DF), proximal tibia (PT), FN, and TH with 46%, 49%, 32%, and 43% of the variance in loss, respectively, described by the exponential decay curves with a time to steady state (tss) occurring at 14.6, 11.3, 14, and 6.2 years, respectively, after SCI. CONCLUSIONS Sublesional bone loss after SCI was marked and occurred as an inverse function of TSI. For aBMD at the hip and knee, tss extended into the second decade after SCI.
