Abstract
Vitamin D is considered to play an important role in musculoskeletal health. It’s classical function is the regulation of calcium and phosphate homeostasis, thus ensuring a balanced bone metabolism that is characterised by an equal amount of bone resorption and bone formation. In the past decades, a plethora of pre-clinical and clinical studies reporting on potential health-beneficial properties of vitamin D have emerged. Moreover, there is an abundance of reports highlighting vitamin D deficiency and insufficiency in patients with almost innumerable diseases. Further, it is estimated that more than one billion people globally are affected by insufficient vitamin D levels. As such, research on vitamin D has been particularly popular over the past years. In orthopaedics and traumatology, most studies describe favourable effects of vitamin D in general. However, the relative importance of vitamin D is oftentimes debated. In this narrative review of the literature, we consider first, the properties of vitamin D and how vitamin D, vitamin D deficiency and the vitamin D receptor (VDR) impact on musculoskeletal health. Secondly, we provide an overview of studies reporting the prevalence of vitamin D deficiency in traumatology and diverse orthopaedic diseases including bone oncology. Lastly, we emphasise recent findings and touch on future perspectives in vitamin D research.

Abstract
Vitamin D deficiency is common in athletes. The conventional measurement of vitamin D levels provides a general indicator of body stores. However, there are nuances in its interpretation as values of 25(OH)D do not correlate absolutely with the amount of 'bioavailable' vitamin to the cells. Vitamin D should be regarded as a hormone and influences between 5% and 10% of our total genome. Determining the precise effect of the vitamin, isolated from the actions of other cofactors, is not straightforward and restricts our complete understanding of all of its actions. Deficiency has harmful effects on not only bone and muscle but also wider areas, including immunity and respiratory and neurological activities. More caution should be applied regarding the ability of supranormal vitamin D levels to elevate athletic performance. Hopefully, future research will shed more light on optimal levels of vitamin D and supplementation regimes, and improved understanding of its intracellular control of our genetic mechanisms and how extrinsic influences modify its activity.

Abstract
BACKGROUND Observational studies report higher blood pressure (BP) among individuals with lower 25-hydroxyvitamin D concentration. Whether dosage of vitamin D supplementation has a differential effect on BP control remains unclear. OBJECTIVE The study aimed to determine if daily vitamin D supplementation with 2000 IU is more effective than 800 IU for BP control among older adults. METHODS This randomized, double-blind, ancillary trial of the Zurich Multiple Endpoint Vitamin D Trial in Knee Osteoarthritis enrolled adults aged ≥60 y who underwent elective surgery due to severe knee osteoarthritis. Participants were randomly assigned to receive high dose (2000 IU) or standard dose (800 IU) daily vitamin D3 for 24 mo. Outcomes included daytime and 24-h mean systolic BP. BP variability and serum 25-hydroxyvitamin D concentration were examined in a post hoc and observational analysis. RESULTS Of the 273 participants randomly assigned, 250 participants completed a follow-up 24-h ambulatory BP monitoring (mean age: 70.4 ± 6.4 y; 47.2% men). The difference in daytime mean systolic BP reduction between the 2000 IU (n = 123) and 800 IU (n = 127) groups was not statistically significant (-2.75 mm Hg vs. -3.94 mm Hg; difference: 1.18 mm Hg; 95% CI: -0.68, 3.05; P = 0.21), consistent with 24-h mean systolic BP. However, systolic BP variability was significantly reduced with 2000 IU (average real variability: -0.37 mm Hg) compared to 800 IU vitamin D3 (0.11 mm Hg; difference: -0.48 mm Hg; 95% CI: -0.94, -0.01; P = 0.045). Independent of group allocation, maximal reductions in mean BP were observed at 28.7 ng/mL of achieved serum 25-hydroxyvitamin D concentrations. CONCLUSIONS While daily 2000 IU and 800 IU vitamin D3 reduced mean systolic BP over 2 y to a small and similar extent, 2000 IU reduced mean systolic BP variability significantly more compared with 800 IU. However, without a placebo control group we cannot ascertain whether vitamin D supplementation effectively reduces BP.This trial was registered at www.clinicaltrials.gov as NCT00599807.

Abstract
OBJECTIVES Our aim was to investigate whether patients presenting with fragility fractures of the proximal femur are receiving osteoporosis treatment and to assess the number of other fragility fractures they have sustained prior to admission. METHODS All patients presenting to our institution with fragility fractures of the proximal femur within an 18-month period (January 2012-August 2013) were included. Patient demographics; fracture classification (AO/OTA); American Society of Anesthesiologists (ASA) grade; Abbreviated Mental Test Score (AMTS) on admission; type of operation; time to operation; peri-operative complications; length of hospital stay (LOS); walking status; osteoporotic medication; Dual-energy X-ray absorptiometry (DEXA) results; additional fragility fractures; and mortality were collected and analysed. RESULTS A total of 1004 patients (278 male) met the inclusion criteria and were included into the study. The mean age was 82.01 years and mean LOS was 19.54days. Fifty-four per cent of the patients were admitted from their own homes whereas 43% were capable to walk indoors without any aids before their injury. Mean time to surgery was 2.06days (Median: 1.31, range: 0-26days). Three hundred and six patients (30.5%) had at least another fragility fracture before the index episode (mean 1.40 fractures; SD: 0.71 fractures; range: 1-6 fractures). Only 16.4% were under complete osteoporosis treatment on admission, defined as receiving calcium with vitamin D and a bisphosphonate or an alternative agent. When we compared patients without a history of a previous fragility fracture (Group A) and patients with at least another previous fragility fracture (Group B), we found that patients in Group B had a significantly lower AMTS score, lower bone mineral density (BMD) as evident on the DEXA scan, an inferior mobility before admission and a higher incidence of extracapsular fractures (p<0.05). On discharge, patients in Group B had a higher chance of receiving complete bone protection compared to group A (27.9% versus 41.7%; p<0.01). Following discharge, 11.2% of the patients sustained an additional fragility fracture. The mean time from the index episode to the additional fracture was 0.65 years, whilst these injuries were more frequent in Group B (RR=1.638; p<0.05). CONCLUSION Patients presenting with a hip fracture are generally under-treated for osteoporosis. Post-operative assessment by a designated geriatrician and use of a standardised protocol is of paramount importance for reducing the risk of additional fragility fractures. Additionally, screening of the elderly population for identifying the patients who suffer from osteoporosis can potentially reduce the risk of sustaining a further fragility fracture.

Abstract
INTRODUCTION Major osteoporotic fractures are steadily increasing due to population aging. Programs of secondary prevention against refracture are essential to decrease morbidity and mortality and the cost for individuals and the society. Vitamin D supplementation and optimization of calcium intake are of a pivotal importance to start specific osteoporosis treatment and for its safety and efficacy. Cholecalciferol is the most widely employed drug for vitamin D supplementation. PURPOSE Aim of this study was to assess the trends in the use of vitamin D supplements containing cholecalciferol in the population of hip fracture patients older than 65 years, resident in the region of Tuscany (Italy) in the years 2011-2015 and to describe vitamin D status in a subgroup of this individuals directly referred to a bone clinic for further evaluation after hip osteoporotic fracture. METHODS Data were retrieved from the electronic anonymous regional administrative database administered by the Region of Tuscany (Italy) in the years 2011-2015 within the T.A.R.Ge.T. project (Trattamento Appropriato delle Rifratture Geriatriche in Toscana, i.e., "Appropriate treatment of geriatric refractures in Tuscany"), a program endorsed by the region itself. Data pertaining to cholecalciferol prescriptions and hospital discharge codes were retrieved and appropriately crossed to get data on the use of cholecalciferol supplements in patients before and after a hip fracture. A retrospective analysis was carried out in a subgroup of subjects (n 254) appropriately referred to the local fracture liaison service after the major osteoporotic fracture and vitamin D status in terms of serum 25(OH) vitamin D levels was assessed. RESULTS The majority of subjects experiencing a hip fracture (98.2% and 88.3% in 2011 and 2015, respectively) did not receive vitamin D supplements at the time of the fracture event. Although a trend in increase in prescriptions for cholecalciferol supplements could be observed in the years of the study, the percentage of treated individuals remained low even after the fracture, since only 30-35% of subjects receives cholecalciferol supplements at one year after the fracture. Cholecalciferol remained the most prescribed drug in this population, while a substantial decrease of cholecalciferol in association with calcium salts was observed. The use of high doses of cholecalciferol has decreased in this population, while diminished the use of the drops has been accompanied by an increase in prescriptions of single monthly dose supplements. CONCLUSIONS The correction of vitamin D inadequacy is preliminary to any treatment for osteoporosis and together with calcium may reduce fracture risk by itself. The prescription of vitamin D supplements is low in patients before and after a hip fracture in a Mediterranean region and despite the overall increase in vitamin use and abuse in the general population. Proper educational programs and active fracture liaison services are needed in order to bridge this gap.

A Resident-led Initiative Improves Screening and Treatment for Vitamin D Deficiency in Patients with Hip Fractures. Clin Orthop Relat Res 2017; 475:264-270. [PMID: 27549989 PMCID: PMC5174045 DOI: 10.1007/s11999-016-5036-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/08/2016] [Accepted: 08/10/2016] [Indexed: 01/31/2023]
Abstract
BACKGROUND Acute hip fractures carry a high risk of morbidity and are associated with low vitamin D levels. Improvements in screening and treating low vitamin D levels may lead to lower fall rates and a lower likelihood of additional fragility fractures. However, patients with low vitamin D levels often remain unassessed and untreated, even after they experience these fractures. QUESTIONS/PURPOSES We wished to determine whether a resident-led initiative can improve (1) screening for and (2) treatment of vitamin D deficiency in patients with acute hip fractures. METHODS Our department initiated a housestaff-led, quality improvement project focused on screening and treating vitamin D deficiency in patients with acute hip fractures. Screening encompassed checking serum 25-hydroxyvitamin D level during the acute hospitalization, and treating was defined as starting supplementation before discharge when the serum 25-hydroxyvitamin D level was less than 30 ng/mL. To evaluate the efficacy of this program, an administrative database identified 283 patients treated surgically for an acute hip fracture between July 2010 and June 2014. This period included 2 years before program initiation (Year 1, n = 65 patients; Year 2, n = 61 patients), the initial program year (Year 3, n = 66 patients), and the subsequent program year (Year 4, n = 91 patients). Followup was extended to 6 weeks after treatment with 9.2% (26/282) of patients lost to followup. Eight patients were excluded owing to documented intolerance of vitamin D supplementation. There were no differences regarding patient demographics, fracture type, or treatment rendered across these 4 years. The primary endpoints were the proportion of patients screened and treated for vitamin D deficiency. The secondary endpoint was the continuation of vitamin D supplementation at the patient's 6 week followup, according to the patient's medication list at that visit. This analysis included all patients, assuming those lost to followup had not continued supplementation. ANOVA and chi-square tests were used to evaluate the differences in demographic data and in screening and treating rates. RESULTS Screening for vitamin D deficiency improved after initiation of the resident-led quality improvement program, with screening performed for 31% of patients in Year 1 (20/65; odds ratio [OR], 0.44; 95% CI, 0.26-0.75), 20% of patients in Year 2 (12/61; OR, 0.24; 95% CI, 0.13-0.46), 46% of patients in Year 3 (30/66; OR, 0.83; 95% CI, 0.51-1.35), and 88% of patients in Year 4 (80/91; OR, 7.27; 95% CI, 3.87-13.7) (p < 0.001). Vitamin D supplementation was initiated for 33% of patients in Year 1 (21/63; OR, 0.5; 95% CI, 0.30-0.84), 28% in Year 2 (17/61; OR, 0.39; 95% CI, 0.22-0.68), 50% in Year 3 (32/64; OR,1.00; 95% CI, 0.61-1.63), and 76% in Year 4 (65/86; OR, 3.10; 95% CI, 1.89-5.06) (p < 0.001). At early postoperative followup, we saw substantial improvement in the proportion of patients who continued receiving vitamin D supplementation: Year 1, 12% (8/64; OR, 0.14; 95% CI, 0.07-0.30); Year 2, 15% (9/61; OR, 0.17; 95% CI, 0.09-0.35); Year 3, 26% (16/64; OR, 0.33; 95% CI, 0.19-0.59); and Year 4, 46% (40/86; OR, 0.87; 95% CI, 0.57-1.33) (p < 0.001). CONCLUSIONS Implementation of a resident-led quality improvement program resulted in higher rates of screening and treating vitamin D deficiency for patients with acute hip fractures. Housestaff-based initiatives may be an effective way to improve care processes that target improvements in bone health.

Abstract
PURPOSE Although vitamin D levels are not routinely monitored in outpatient fracture patients, identification of fracture patients with a deficient vitamin D status may be clinically relevant because of the potential role of vitamin D in fracture healing. This study aimed to determine the prevalence of and risk factors for vitamin D deficiency in non-operatively treated adult fracture patients. PATIENTS AND METHODS Vitamin D levels were determined in a cross-sectional study of adult patients, who were treated non-operatively for a fracture of the upper or lower extremity in the outpatient clinic of a level 1 trauma center, during one calendar year. Potential risk factors for (severe) vitamin D deficiency were analyzed using multivariable logistic regression analysis. RESULTS A total of 208 men and 319 women with a mean age of 49.7 years (SD 19.9) were included. In this population, 71 % had a serum calcidiol <75 nmol/L, 40 % were vitamin D deficient (serum calcidiol <50 nmol/L) and 11 % were severely vitamin D deficient (serum calcidiol <25 nmol/L). Smoking and season (winter and spring) were independent risk factors for vitamin D deficiency. An increasing age, a non-Caucasian skin type, winter and smoking were identified as independent risk factors for severe vitamin D deficiency. The use of vitamin D, alcohol consumption and higher average daily sun exposure were independent protective factors against (severe) vitamin D deficiency. CONCLUSION Given the potential role of vitamin D in fracture healing, clinicians treating adult fracture patients should be aware of the frequent presence of vitamin D deficiency during the winter, especially in smoking and non-Caucasian patients. Research on the effect of vitamin D deficiency or supplementation on fracture healing is needed, before suggesting routine monitoring or supplementation.

Abstract
Hypovitaminosis D has been identified as a common risk factor for fragility fractures and poor fracture healing. Epidemiological data on vitamin D deficiency have been gathered in various populations, but the association between vertebral fragility fractures and hypovitaminosis D, especially in males, remains unclear. The purpose of this study was to evaluate serum levels of 25-hydroxyvitamin D (25-OH D) in patients presenting with vertebral fragility fractures and to determine whether patients with a vertebral fracture were at greater risk of hypovitaminosis D than a control population. Furthermore, we studied the seasonal variations in the serum vitamin D levels of tested patients in order to clarify the relationship between other known risk factors for osteoporosis and vitamin D levels. We measured the serum 25-OH D levels of 246 patients admitted with vertebral fractures (105 men, 141 female, mean age 69 years, sd 8.5), and in 392 orthopaedic patients with back pain and no fractures (219 men, 173 female, mean age 63 years, sd 11) to evaluate the prevalence of vitamin D insufficiency. Statistical analysis found a significant difference in vitamin D levels between patients with vertebral fragility fracture and the control group (p = 0.036). In addition, there was a significant main effect of the tested variables: obesity (p < 0.001), nicotine abuse (p = 0.002) and diabetes mellitus (p < 0.001). No statistical difference was found between vitamin D levels and gender (p = 0.34). Vitamin D insufficiency was shown to be a risk factor for vertebral fragility fractures in both men and women.

Abstract
OBJECTIVES The aim of this study was to evaluate the association between serum levels of 25(OH) vitamin D3 with midupper arm muscle circumference (MUAMC), handgrip strength and length of hospital stay (LOS) after hip fracture. METHODS In total, 102 consecutive patients with hip fracture over the age of 65 were admitted to the orthopedic unit and prospectively evaluated. All of the patients were treated according to specific protocols depending on the type of fracture. Anthropometric measurements and handgrip strength were performed, and blood samples were taken for serum biochemistry and 25(OH) vitamin D3 analysis within the first 72 h of admission. All of the patients were followed during their hospital stay, and the length of stay was recorded. RESULTS Of the patients, two were excluded because of pathologic fractures. In total, 100 patients with a mean age of 80 ± 7 y were included in the analysis. Among these patients, 73% were female, and 37% had vitamin D deficiency. The median LOS was 7 (5-11) d. Patients with vitamin D deficiency had lower handgrip strength in univariate analysis. In the multiple linear regression analysis with robust standard error, serum vitamin D levels adjusted by age and sex were associated with handgrip strength but not with MUAMC and LOS after hip fracture. CONCLUSIONS In conclusion, vitamin D serum levels were associated with handgrip strength but not with muscle mass or length of hospital stay after hip fracture.

Abstract
PURPOSE OF REVIEW The aim of treatment in patients at high risk for fractures is to reduce the risk of a first or a subsequent fracture. New data are available on the antifracture effects and side-effects of antiresorptive and osteoanabolic drugs, and new emerging therapies with new modes of action are on the horizon. RECENT FINDINGS Calcium and vitamin D intake should be sufficient, but not too high. Vertebral, nonvertebral (including hip fracture) prevention with antiresorptive drugs such as bisphosphonates (alendronate, risedronate and zoledronic acid) and denosumab exceeds the risk of rare side-effects such as atypical femur fracture and osteonecrosis of the jaw. Teriparatide is an osteoanabolic drug that improves quality of life in severe osteoporosis. Strontium ranelate decreases dynamic parameters of bone formation during the first year of treatment, and could increase the risk of cardiovascular events in high-risk patients. Initiation of and adherence to fracture prevention drugs are still low. New potential developments in antiresorptive drugs include odanacatib, a selective inhibitor of cathepsin K, and, in osteoanabolic drugs, monoclonal antibodies against sclerostin. SUMMARY These recent data indicate that fracture prevention with antiresorptives and teriparatide is effective with a reasonable safety profile. Odanacatib and antisclerostin are promising new drugs with new mechanisms of action, as they are able to disconnect the normal coupling between bone resorption and bone formation.

Abstract
UNLABELLED This study of elderly Swedish women investigated the association between chronic vitamin D insufficiency and osteoporotic fractures occurring between ages 80-90. The incidence and risk of hip and major osteoporotic fractures was significantly higher in elderly women with low vitamin D levels maintained over 5 years. INTRODUCTION Vitamin D insufficiency among the elderly is common; however, relatively little is known about the effects of long-term hypovitaminosis D on fracture. We investigated sequential assessment of serum 25(OH)D at age 75 and 80 to determine if continuously low 25(OH)D levels are associated with increased 10-year fracture incidence. METHODS One thousand forty-four Swedish women from the population-based OPRA cohort, all 75 years old, attended at baseline (BL); 715 attended at 5 years. S-25(OH)D was available in 987 and 640, respectively and categorized as: <50 (Low), 50-75 (Intermediate), and >75 nmol/L (High). Incident fracture data was collected with maximum follow-up to 90 years of age. RESULTS Hip fracture incidence between age 80-85 was higher in women who had low 25(OH)D at both baseline and 5 years (22.2 % (Low) vs. 6.6 % (High); p = 0.003). Between age 80-90, hip fracture incidence was more than double that of women in the high category (27.9 vs. 12.3 %; p = 0.006). Within 5-years, 50 % of women in the continuously low group compared to 34 % in the continuously high 25(OH)D group had an osteoporotic fracture (p = 0.004) while 10-year incidence was higher compared to the intermediate (p = 0.020) but not the high category (p = 0.053). The 10-year relative risk of hip fracture was almost three times higher and osteoporotic fracture risk almost doubled for women in the lowest 25(OH)D category compared to the high category (HR 2.7 and 1.7; p = 0.003 and 0.023, respectively). CONCLUSION In these elderly women, 25(OH)D insufficiency over 5-years was associated with increased 10-year risk of hip and major osteoporotic fractures.

Abstract
BACKGROUND Vitamin D deficiency is common in elderly patients with hip fracture, and clinical practice guidelines recommend screening this population. Our hospitalist group cares for all patients admitted with hip fracture, yet lacked a standardized approach to screening for and treating vitamin D deficiency in this population. OBJECTIVES To standardize and improve the assessment and treatment of vitamin D deficiency in elderly patients with hip fracture. DESIGN Quality improvement implementation. SETTING Tertiary academic hospital. PATIENTS Adults age >50 years with hip fracture. INTERVENTIONS We implemented a computerized hip fracture order set with preselected orders for 25-OH vitamin D level and initial supplementation with 1000 IU/day of vitamin D. We presented a review of the literature and performance data to our hospitalist group. MEASUREMENTS Percentage of patients with acute hip fracture screened for vitamin D deficiency and percentage of deficient or insufficient patients discharged on recommended dose of vitamin D (50,000 IU/wk if level <20 ng/mL). RESULTS The percentage of patients screened for vitamin D deficiency improved from 37.2% (n = 196) before implementation to 93.5% (n = 107) after (P < 0.001). The percentage of deficient or insufficient patients discharged on the recommended vitamin D dose improved from 40.9% to 68.0% (P = 0.008). The prevalence of vitamin D deficiency or insufficiency (25-OH vitamin D level <30 ng/mL) was 50.0%. CONCLUSIONS Simple interventions, consisting of a change in computerized order set and presentation of evidence and data from group practice, led to significant improvement in the assessment and treatment of vitamin D deficiency in elderly patients with hip fracture.

Abstract
Atraumatic bilateral hip fractures in the relatively young are exceedingly rare. In this case report, we present one such patient diagnosed by MRI and treated with bilateral hip screws. Subsequent investigations revealed severe osteoporosis and primary 25-hyroxyvitamin D (25OHD) deficiency at a level suggestive of concurrent osteomalacia.
