How can the orthopedic surgeon ensure optimal vitamin D status in patients operated for an osteoporotic fracture?

In this narrative review, the role of vitamin D deficiency in the pathophysiology, healing of fragility fractures, and rehabilitation is discussed. Vitamin D status can be assessed by measuring serum 25(OH)-vitamin D level with standardized assays. There is a high prevalence of vitamin D insufficiency (25(OH)D < 50 nmol/l (i.e., 20 ng/mL)) or deficiency (25(OH)D < 25 nmol/l (i.e., 10 ng/mL)) in patients with fragility fractures and especially in those with a hip fracture. The evidence on the effects of vitamin D deficiency and/or vitamin D supplementation on fracture healing and material osseointegration is still limited. However, it appears that vitamin D have a rather positive influence on these processes. The fracture liaison service (FLS) model can help to inform orthopedic surgeons, all caregivers, and fractured patients about the importance of optimal vitamin D status in the management of patients with fragility fractures. Therefore, vitamin D status should be included in Capture the Fracture® program as an outcome of FLS in addition to dual-energy X-ray absorptiometry (DXA) and specific antiosteoporosis medication. Vitamin D plays a significant role in the pathophysiology and healing of fragility fractures and in rehabilitation after fracture. Correction of vitamin D deficiency should be one of the main outcomes in fracture liaison services.

Are Dietary Supplements and Nutraceuticals Effective for Musculoskeletal Health and Cognitive Function? A Scoping Review.

OBJECTIVE: The aim of our scoping review was to summarize the state of the art regarding micronutrients in order to identify which of them might effectively improve health status in the areas typically impaired in older people: bone, skeletal muscle, and cognitive function. DESIGN: Scoping review. METHODS: The Italian Study Group on Healthy Aging by Nutraceuticals and Dietary Supplements (HANDS) performed this scoping review, based on the following steps: doing a list of micronutrients related with musculoskeletal or cognitive functions, included in dietary supplements and nutraceuticals commercialized in Italy; planning a research on PubMed, according to an evidence-based approach, in order to the most relevant positive study for each micronutrient into each of the three areas involved (bone, skeletal muscle and cognitive function); identifying the micronutrients effective in maintaining or achieving an adequate health status in older people, specifying the effective and safe daily doses, according to the selected studies. RESULTS: In literature we found 12 relevant positive studies (1 international society guidelines/recommendations, 1 systematic review, 7 randomized controlled trials, and 3 prospective cohort studies). We showed that only 16 micronutrients resulted to have appropriate scientific evidences in terms of improving musculoskeletal health and/or cognitive function in older people: beta-alanine, calcium, creatine, fluorides, leucine, magnesium, omega-3 fatty acids, potassium, vitamin B6, vitamin B9, vitamin B12, vitamin C, vitamin D, vitamin E, vitamin K2, and zinc. CONCLUSION: This scoping review showed that selected micronutrients in adequate doses might have an ancillary role in musculoskeletal health and cognitive functions in older people.

Baseline characteristics of the population enrolled in the Italian Observational Study on Severe Osteoporosis (ISSO).

OBJECTIVES: Baseline characteristics of the population enrolled in the ISSO study, designed to evaluate the incidence of vertebral and non-vertebral fractures in Italian patients with severe osteoporosis treated according to clinical practice over 24 months observation. METHODS: Prospective observational study in 783 post-menopausal women and men entering 18-month treatment with teriparatide in a community setting at 57 centres in Italy. Characterisation included demographics, fracture risk factors, bone mineral density, fracture status, Health-Related Quality of Life (HRQoL) measured by the European Quality of Life Questionnaire, EQ-5D, and back pain assessed by VAS. RESULTS: Most patients were elderly women (90.5%), mean age±SD was 72.9±8.8 years. Nearly all (91.3%) had experienced ≥ 1 vertebral fracture (mean±SD, 3.6±2.2 per patient), 37.5% had ≥ 1 non-vertebral fracture (mean±SD, 1.4±0.7 per patient). Nearly all patients were suffering from back pain (94.9%), which had significantly restricted their daily activities (51.7%) and had likely or very likely been caused by vertebral fractures (29.2% and 55.8%, respectively). Mean EuroQoL EQ-5D index value was 0.58±0.25 and VAS score 49.2±23.6. Non-vertebral fractures, back pain and multiple vertebral fractures were associated with lower HRQoL (EuroQoL-5D Index both p<0.001, EQ-5D VAS score p=0.025 and p<0.016, respectively). Many patients were physically inactive (81.1%). One third (34.7%) of population had co-morbidities and 60.5% were on chronic concomitant treatments. Few subjects reported a maternal history of osteoporosis (15.5%), regular consumption of alcohol (13.3%) or were current smokers (11.5%). Nearly two-thirds (71.5%) had already been treated for osteoporosis, mainly with bisphosphonates. Calcium and vitamin D supplements were taken by 13% and 15.5% of the total population, respectively. CONCLUSIONS: At enrollment, the population of ISSO study mostly consisted in aging women, who had osteoporosis with high fracture risk, poor HRQoL and suffered from significant back pain. Most of them had already been treated by bisphosphonates but without calcium and vitamin D supplements. Back pain, as well as non-vertebral and multiple vertebral fractures, were associated with lower HRQoL.
