RESUMEN

PURPOSE: We aimed at updating our previous researches about the burden of hip fractures in elderly Italian population. METHODS: We analyzed national hospitalizations records from 2000 to 2014 to compute age- and sex-specific standardized rates. RESULTS: 1,335,375 hospitalizations were recorded in people ≥ 65 (1,031,816 women: 77.27% and 303,559 men: 22.73%) over 15 years, passing from 73,493 in year 2000 to 94,525 in 2014, with an overall increase of 28.62% over the 15-year period (females: + 25.1%; males: + 41.2%). About 84.9% of total hip fractures were suffered by patients aged ≥ 75 years old. Direct hospitalization costs and rehabilitation costs increased from 343 to 457 million Euros and from 392 to 504 million Euros from year 2000 to 2014, respectively. Overall costs of hip fractures raised from 735 to 961 million Euros (+ 30.74% from 2000 to 2014). CONCLUSION: The number of hip fractures and related hospitalizations costs in Italian elderly population is still increasing due to the absolute number of fractures occurring in people ≥ 65 years old and particularly over 75 years old.

RESUMEN

BACKGROUND: Sarcopenia, osteoporosis and osteoarthritis are the most frequent musculoskeletal disorders affecting older people. The main aim of this study was to test the hypothesis that the balance between BMPs and myostatin pathways regulates the age-related muscle degeneration in OP and OA patients. To this end, we investigated the relationship among the expression of BMP-2/4-7, myostatin and phosphorylated Smads1-5-8 and the muscle quality, evaluated in term of fibers atrophy and satellite cells activity. METHODS: In this retrospective study, we collected 123 biopsies of vastus lateralis: 48 biopsies from patients who underwent hip arthroplasty for subcapital fractures of the femur (OP), 55 biopsies from patients who underwent hip arthroplasty for osteoarthritis (OA) and 20 biopsies from patients who underwent hip arthroplasty for high-energy hip fractures (CTRL). Muscle biopsies were fixed in 4% paraformaldehyde and paraffin embedded. Serial sections were used for morphometrical and immunohistochemical analysis (BMP/2/4-7, myostatin, Smads1-5-8, Pax7 and myogenin). In addition, 1 mm3 of muscle tissue of each patient was embedded in epon for ultrastructural study. RESULTS: Morphometric data indicated an increase of the number of atrophic fibers in OP patients compare to OA. In line with these data, we found an high regenerative potential in muscle tissues of OA patients due to the significant amount of both Pax7 and myogenin positive satellite cells detected in OA group. In addition, our data showed the decrease of BMP2/4 and -7 expression in OP patients compared to both OA group and CTRL. Conversely, OP patients were characterized by high levels of myostatin expression. A different expression profile was also found for phosphorylated Smad1-5-8 between OP and OA patients. In particular, OP patients showed a low number of positive phosphorylated Smad1-5-8 nuclei. CONCLUSION: The identification of molecular pathways involved in the pathogenesis of sarcopenia open new prospective for the development of drugs able to prevent/treat the muscle impairment that occur in elderly. Results here reported, highlighting the role of BMPs and myostatin pathways in physio-pathogenesis of human sarcopenia, allow us to propose human recombinant BMP-2/7 and anti-myostatin antibodies as a possible therapeutic option for the sarcopenia.

RESUMEN

Bone metabolism is affected by mechanical, genetic, and environmental factors and plays a major role in osteoporosis. Nevertheless, the influence of environmental pollution on the occurrence of osteoporosis is still unclear and controversial. In this context, heavy metals are the most important pollutants capable to affect bone mass. The aim of this study was to investigate whether heavy metals accumulation in bone tissues could be related to the altered bone metabolism and architecture of osteoporotic patients. To this end, we analyzed 25 bone head biopsies osteoporotic patients and 25 bone head biopsies of osteoarthritic patients. Moreover we enrolled 15 patients underwent hip arthroplasty for high-energy hip fracture or osteonecrosis of the femoral head as a control group. Bone head biopsies were studied by BioQuant-osteo software, scanning electron microscopy and Energy Dispersive X-ray microanalysis. We found a prevalence of lead, cadmium and chromium accumulation in osteoporotic patients. Noteworthy, high levels of sclerostin, detected by immunohistochemistry, correlate with the accumulation of heavy metal found in the bone of osteoporotic patients, suggesting a molecular link between heavy metal accumulation and bone metabolism impairment. In conclusion, the presence of heavy metals into bone shed new light on the comprehension of the pathogenesis of osteoporosis since these elements could play a non redundant role in the development of osteoporosis at cellular/molecular and epigenetic level. Nevertheless, in vivo and in vitro studies need to better elucidate the molecular mechanism in which heavy metals can participate to osteoporosis. © 2016 Wiley Periodicals, Inc.

RESUMEN

Osteoporosis has a significant impact on affected patients. Healthcare providers should encourage postmenopausal women to improve self-care maintenance behaviors and quality of life following a fragility fracture. The aims of this study were to a) develop two new instruments for measuring, respectively, self-care maintenance and quality of life, in postmenopausal women with osteoporosis; b) evaluate the effectiveness of a tailored educational intervention to improve self-care maintenance and quality of life after a fragility fracture in postmenopausal women. For the first aim, a cross-sectional study will be performed; for the second aim, a multicenter, quasi-experimental, interventional design will be used. A convenience sample of postmenopausal women admitted to 44 hospitals in Italy with a diagnosis of bone fragility fracture will be enrolled and surveyed at 7, 30, 60 and 180 days after discharge. Trained nurses will conduct the educational intervention. The new instruments will allow the measurement of self-care and quality of life in postmenopausal women following a fragility fracture. Through tailored educational interventions, women can be helped to take their medications correctly, adopt a healthy lifestyle, reduce the occurrence of bone fractures, and have a better quality of life.

RESUMEN

BACKGROUND: Diabetes induces bone alterations accompanied by altered cytokine expression patterns. These alterations lead to modified fracture healing, contributing to musculoskeletal fragility in the elderly. AIMS: We evaluated the inflammatory immune response in diabetic patients during fracture healing relative to clinical and radiographic assessments. METHODS: Fifty patients of both sexes with fragility fractures were studied: 30 diabetics (group A, mean age 73.4 ± 11.2 years) and 20 normoglycemic controls (group B, mean age 75.1 ± 16.9 years). Two subgroups comprised those with hip or wrist fragility fractures (25 and 16 patients, respectively). We evaluated serum concentrations of tumor necrosis factor α, interleukins 4 and 8, monocyte chemotactic protein-1 (MCP-1), vascular endothelial growth factor, and epidermal growth factor (EGF) before and at 4 and 8 weeks after surgery. We also determined the Radiographic Union Score for Hips and the Radius Union Scoring System score and applied the Physical Activity Scale for the Elderly test at the same time points. Each patient underwent bone densitometry. RESULTS: MCP-1 and EGF levels were higher in group A than in group B at 4 weeks after surgery (p > 0.05). Radiographic evaluation showed lower scores in group A (p < 0.05). The main difference between the groups was evident 4 weeks after surgery. Changes in the serum concentrations of chemotactic and angiogenic factors could explain the radiographically proved impaired fracture healing in diabetic patients. CONCLUSIONS: Fragility fracture healing is impaired in diabetic patients. Radiographic and molecular patterns confirmed that the most compromised fracture-healing phase is at 4 weeks after surgery, during callus mineralization.

RESUMEN

Osteoporosis mostly affects females over 50 years old, worldwide. The main osteoporosis complication is fragility fractures that reduce quality of life and cause morbidity and mortality. Most patients who have fragility fractures are treated for the fracture. However, patients' adherence to follow-up treatment plans is poor. Therefore, tailored educational interventions are needed to improve medication adherence and healthy lifestyles. In this context, the role of bone care nurses is important, as they can act at different levels of osteoporosis prevention and fracture liaison services, which are secondary fracture prevention programmes implemented by health care systems to treat osteoporotic patients. In Italy, a research project called Guardian Angel(®) was developed to provide tailored education to osteoporotic women in order to improve their disease management and reduce related complications.

RESUMEN

In the last years, the number of total hip arthroplasty is increased both in young patients and elderly with a poor bone quality due to extension of surgical indications. According to this trend, also revision surgery showed a growth of its number, especially in elderly patients, because of implant loosening, failed osseointegration of prosthetic components, errors in biomechanical restoration and infections. The aim of this study is to analyze life quality improvement through evaluation of articular functionality and postoperative pain, and to examine osseointegration of implant components with periprosthetic bone. During total hip arthroplasty revision, the orthopedic surgeon often has to face complex cases, especially in elderly patients with a preexisting status of poor bone quality and sarcopenia. In these cases, a correct planning and a surgical procedure well-executed are able to ensure a good outcome that led to pain relief and functional recovery. Furthermore anti-osteoporotic therapy surely represents a useful resource both in primary total hip arthroplasty and in revisions, mainly for elderly patients with a poor bone quality.

RESUMEN

Osteoporosis is a diffuse skeletal disease in which a decrease in bone strength leads to an increased risk of fractures. A wide variety of types of bone densitometry measurements are available, including quantitative computed tomography measurements of the spine, quantitative ultrasound devices for measurements of the heel and other peripheral sites and dual-energy X-ray absorptiometry (DXA) for measurement of bone mineral density (BMD) at the lumbar spine, proximal femur, forearm and total body scans. Compared with alternative bone densitometry techniques, hip and spine DXA examinations have a number of advantages that include a consensus that BMD results can be interpreted using the World Health Organization T score definition of osteoporosis, a proven ability to predict fracture risk, proven effectiveness at targeting anti-fracture therapies, and the ability to monitor response to treatment. However, in recent years, the authors have raised some important questions about the objective limits of this method that have led to doubts about its effectiveness in terms of clinical outcome.

RESUMEN

Osteoporosis and sarcopenia are the most frequent musculoskeletal disorders affecting older people. Osteoporosis is a widespread disorder affecting millions of individuals of all ethnic backgrounds worldwide, particularly among older women. It is characterized by reduced bone mass and microarchitectural deterioration of bone tissue, with a consequent increase in the risk of fracture. Sarcopenia is considered to be one of the major factors responsible for functional limitations and motor dependency in elderly persons. In age-related muscle atrophy, a decrease in muscle fiber size and number, and a preferential loss of type II fibers have been reported. A decrease in the circulating levels of specific hormones (e.g., estrogen, testosterone, growth hormone, and insulin-like growth factor-1) has been shown to be associated with sarcopenia and this appears to play an important role in its pathogenesis.

RESUMEN

We analyzed for the first-time hospitalizations and costs for hip fractures in the elderly Italian population at the regional level from 2007 to 2014. The number of fractures and the overall costs increased, mainly due to people aged > 85 in all the Italian regions, although at different rates. OBJECTIVE: We aimed at evaluating the burden of hip fractures in elderly Italian population at the regional level. METHODS: We analyzed national hospitalizations records 2007-2014 to compute standardized hospitalizations rates (SHR) due to hip fractures per 10,000 inhabitants at the regional level and average annual percent change (AAPC), along with related costs. RESULTS: Hip fractures occurred in people over 65 years increased from 89,601 to 94,525 over 8 years. The overall increase in the number of hospitalizations is attributable only to people aged ≥85. Actually, in the 65-74 and 74-84 age groups, total hospitalizations decreased from 13,396 to 12,268 and from 40,733 to 37,786 respectively, while they increased from 35,472 to 44,471 in people aged ≥85 (women = 28,605 and men = 6,867 in 2007; women = 34,636 and men = 9,835 in 2014). Almost 50% of hip fractures were found to have been experienced by patients aged 85 or older in 2014 (with women ≥ 85 representing 36.6% of total fractures), in accordance with the higher prevalence of osteoporosis in this age group. Fractures increase in people aged ≥ 85 was two-folds higher in males (AAPC: + 5.0%; P > 0.05) than in females (AAPC: + 2.6%; P > 0.05). Increases in the number of hospitalizations and related costs were observed for all the regions, with the only exception of Lazio (AAPC: - 4.6%; P < 0.05) and Friuli Venezia Giulia (hip fractures AAPC: - 1.9%; P < 0.05). The most significant increases in hip fractures and related costs were recorded in Calabria (+ 2.7%), Campania (+ 2.2%), and Lombardia (+ 2.0%). At the national level, SHR per 10,000 inhabitants due to hip fractures decreased in all three examined age groups (65-74, 75-84, and ≥ 85), both in males and females during the 8-year period (P < 0.05). This reduction was confirmed also when looking at the regional dataset, with few exceptions concerning female population (AAPC not statistically significant). When looking at the SHR per 10,000 inhabitants for the entire nation, we recorded a decreasing trend also in females aged 85 years old and over but not in males ≥ 85. Actually, men aged ≥ 85 showed increased HR per 10,000 in 10 regions out of 20. Direct hospitalization and rehabilitation costs increased in all the regions over the 8-year period (although at different rates), except for Friuli Venezia Giulia (where costs decreased from 21 to 19 million Euros) and Lazio (from 107 to 87 million Euros). Lombardia and Piemonte were the regions spending the highest amount of money to treat hip fractures in elderly people (151 and 95 million Euros in the year 2014, respectively). CONCLUSION: Hip fractures in the elderly population remain a major public health issue in all Italian regions, especially in people aged 85 years old and over, although the problem is starting to become more controlled compared with the past. Women represent the majority of hip fractures, but the highest increasing rate has been observed in men. Pilot projects at regional level targeting elderly people at higher risk of fractures and treatment compliance are needed.

RESUMEN

Glenoid bone loss and capsular deficiency represent critical points of arthroscopic Bankart repair failures. The purpose of this Technical Note is to present an all-arthroscopic bone block procedure associated with arthroscopic subscapularis augmentation for treating glenohumeral instability with glenoid bone loss and anterior capsulolabral deficiency. Two glenoid tunnels are set up from the posterior to the anterior side using a dedicated bone block guide, and 4 buttons are used to fix the graft to the glenoid. The subscapularis tenodesis is performed using a suture tape anchor. This combined arthroscopic technique (bone block associated with arthroscopic subscapularis augmentation) could be a valid and safe alternative to the arthroscopic or open Latarjet procedures.

RESUMEN

We analyzed hospitalization for hip fractures in elderly Italian people from 2007 to 2014. The number of fractures increased by 5.50% (women + 3.36; men + 12.9%) only due to people aged ≥ 85 years old. Incidence rates per 10,000 inhabitants decreased in all the age groups (65-74, 75-84, and also ≥ 85). PURPOSE: To assess the burden of hip fractures in elderly Italian population moving from our previous researches documented a reduced incidence of hip fractures in Italian women aged 65-74 years old. METHODS: We analyzed national hospitalization records from 2007 to 2014 to compute age- and sex-specific rates at national and regional level. RESULTS: Seven hundred forty-one thousand six hundred thirty-three a total of 741,633 hospitalizations were observed in people ≥ 65 (women 568,203; men 173,430), with an overall increase of 5.50% over the 8-year period (females + 3.36; males + 12.9%). About 43.75% of total hip fractures were suffered by patients aged ≥ 85 years old. Women aged ≥ 85 accounted for 34.49% (n = 255,763) of total fractures. The incidence rate per 10,000 inhabitants in people aged 65-74 decreased from 28.65 to 25.31 in women (- 13.02%) and from 13.41 to 11.65 in men (- 13.12%). Incidence per 10,000 in people 75-84 decreased from 121.6 to 105.2 in women (- 13.49%) and from 55.8 to 47.5 in men (- 14.87%). Also, in people aged ≥ 85, the incidence per 10,000 declined from 300.99 to 268.72 in women (- 10.72%) and from 174.59 to 171.17 in men (- 1.96%). Standardized rates (SR) per 10,000 in the overall population aged 65 years old and over decreased between 2007 and 2014 from 22.9 to 20.1 and from 7.0 to 6.3 in women and men, respectively. Decreasing trends were documented in all Italian regions between 65 and 79 years old, with further reduction up to 84 years old in 16 regions out of 20. Region Lazio showed a decreasing trend also in people aged > 85 years old. CONCLUSION: While the number of hospitalizations for hip fractures in Italy is still increasing due to the fractures occurring in people ≥ 85 years old, incidence rates are decreasing in all the age groups, including the oldest one, possibly because the number of subjects aged ≥ 85 is growing faster than the number of fractures.

RESUMEN

Pentraxin 3 (PTX3) is a multifunctional glycoprotein regulating inflammatory response, cell proliferation and migration and deposition and remodelling of the extracellular matrix by a variety of cells. In this study, we investigated the possible role of PTX3 in bone homeostasis. To this end, we compared the expression and function of PTX3 in human osteoblasts of osteoporotic, osteoarthritic patients and young subjects not affected by bone diseases. Immunohistochemical analysis performed on bone head biopsies showed a close association between bone health and the number of osteoblasts expressing PTX3. Noteworthy, the proportion of PTX3-positive osteoblasts resulted to be significantly lower in osteoporotic patients compared with both young patients and osteoarthritic patients of the same age. Ex vivo culture of osteoblasts isolated from the three groups of patients confirmed in vivo observation. Specifically, we observed rare runt-related transcription factor 2 (RUNX2) immunopositive osteoblasts expressing PTX3 in cell cultures derived from osteoporotic patients and western blotting analysis showed 80% reduction of PTX3 in the corresponding culture extracts compared with young and osteoarthritic patients. The treatment of human osteoblast primary cultures derived from young patients with anti-PTX3 antibody dramatically affected osteoblast behaviour. Indeed, they lost the morphological and molecular features typical of mature osteoblasts, acquiring fibroblast-like shape and highly decreasing nuclear factor kappa-B ligand (RANKL) and RUNX2 expression. Also, the inhibition of PTX3 negatively affected osteoblast proliferation and their ability to form cell clusters and microhydroxyapatite crystals. Altogether, these results suggest a central role of PTX3 in bone homeostasis showing its involvement in osteoblast proliferation, differentiation and function.

RESUMEN

INTRODUCTION: Osteoporosis is characterised by poor bone quality arising from alterations to trabecular bone. However, recent studies have also described an important role of alterations to cortical bone in the physiopathology of osteoporosis. Although dual-energy X-ray absorptiometry (DXA) is a valid method to assess bone mineral density (BMD), real bone fragility in the presence of comorbidities cannot be evaluated with this method. The aim of this study was to evaluate if cortical thickness could be a good parameter to detect bone fragility in patients with hip fracture, independent of BMD. METHODS: A retrospective study was conducted on 100 patients with hip fragility fractures. Cortical index was calculated on fractured femur (femoral cortical index [FCI]) and, when possible, on proximal humerus (humeral cortical index [HCI]). All patients underwent densitometric evaluation by DXA. RESULTS: Average value of FCI was 0.43 and of HCI was 0.25. Low values of FCI were found in 21 patients with normal or osteopenic values of BMD, while low values of HCI were found in three patients with non-osteoporotic values of BMD. DISCUSSION AND CONCLUSION: Cortical thinning measured from X-Ray of the femur identifies 21% additional fracture cases over that identified by a T-score <-2.5 (57%). FCI could be a useful tool to evaluate bone fragility and to predict fracture risk even in patients with normal and osteopenic BMD.

Poor adherence to medication and an unhealthy lifestyle increase risk of fracture, hospitalization, and medical costs in osteoporotic individuals. Therefore, a literature review was conducted using PubMed, CINAHL, Cochrane Library, and Scopus databases to identify educational interventions that improve adherence to medications and healthy lifestyles in osteoporotic women. The search was limited to the articles published between January 2002 and January 2015, and they were selected only if they were interventional studies. Twelve studies were included, in which 7 studies were focused on interventions to improve medication adherence, 4 studies on improving adherence to healthy lifestyles, and 1 study was focused on both. Educational interventions, such as tailored interventions with counseling sessions, were effective in improving adherence to medications and healthy lifestyles; however, educational materials such as leaflets did not improve adherence. Further studies are needed to investigate adherence to healthy lifestyles because this is poorly described in the literature.

RESUMEN

Although an inverse relationship between osteoarthritis (OA) and osteoporosis (OP) has been shown by some studies, other reports supported their coexistence. To clarify this relationship, we analyzed the interplay between clinical and histomorphometric features. Bone mineral density (BMD) and histomorphometric structure were assessed in 80 patients of four different age-matched groups undergoing hip arthroplasty for severe OA or OP-related femoral fracture. Harris Hip Score was also performed. Surgical double osteotomy of the femoral head was performed and microscopic bone slice samples analysis was performed by using a BioQuant Osteo software. Bone volume fraction (BV/TV) was lower (P < 0.01) in subjects with femoral neck fracture (20.77 ± 4.34%) than in subjects with nonosteopenic OA (36.49 ± 7.73%) or osteopenic OA (32.93 ± 6.83%), whereas no difference was detected between subjects with femoral neck fractures and those with combined OA and OP (20.71 ± 5.23%). Worse Harris Hip Score was found in those patients with the lowest BMD and BV/TV values. Our data support recent evidences indicating the possibility of impaired bone volume fraction in OA patients, with a high risk of developing OP, likely for their decreased mobility. Further studies are needed in order to investigate biomolecular pathway and/or growth factors involved in bone volume impairment in OA patients.

RESUMEN

Fracture healing is a complex event that involves the coordination of different processes: initial inflammatory response, soft and hard callus formation, initial bony union and bone remodeling. This well-orchestrated series of biological events follows a specific temporal and spatial sequence that can be affected by biological factors, such as age and bone quality. There is some evidence that increased age is a considerable factor in the inhibition of fracture repair in human subjects. During aging there is an accumulation of damage that depends on the activation of inflammation processes and on changes in the circulating levels of inflammatory cytokines. In addition to the physiological slow down in the repair process, other conditions such as multiple comorbidities leading to polymedication are a frequent occurrence in elderly patients and can have an influence on this process. A further factor that affects bone metabolism is nutrition: bone quality, fragility fractures risk and fracture healing process are all influenced by the nutritional status. This review provides a summary of the immunological aspects of physiological fracture healing and of those nutritional factors which might play an important role in this process.

RESUMEN

AIM: To evaluate the hospitalization rate of femoral neck fractures in the elderly Italian population over ten years. METHODS: We analyzed national hospitalizations records collected at central level by the Ministry of Health from 2000 to 2009. Age- and sex-specific rates of fractures occurred at femoral neck in people ≥ 65 years old. We performed a sub-analysis over a three-year period (2007-2009), presenting data per five-year age groups, in order to evaluate the incidence of the hip fracture in the oldest population. RESULTS: We estimated a total of 839008 hospitalizations due to femoral neck fractures between 2000 and 2009 in people ≥ 65, with an overall increase of 29.8% over 10 years. The incidence per 10000 inhabitants remarkably increased in people ≥ 75, passing from 158.5 to 166.8 (+5.2%) and from 72.6 to 77.5 (+6.8%) over the ten-year period in women and men, respectively. The oldest age group (people > 85 years old) accounted for more than 42% of total hospital admissions in 2009 (n = 39000), despite representing only 2.5% of the Italian population. Particularly, women aged > 85 accounted for 30.8% of total fractures, although they represented just 1.8% of the general population. The results of this analysis indicate that the incidence of hip fractures progressively increased from 2000 to 2009, but a reduction can be observed for the first time in women ≤ 75 (-7.9% between 2004 and 2009). CONCLUSION: Incidence of hip fractures in Italy are continuously increasing, although women aged 65-74 years old started showing a decreasing trend.

RESUMEN

The deepening knowledge about bone pathophysiology, together with the development of less invasive bone implants, fitted for the treatment of fragility fractures, the continuous advances in the creation of osteoconductive and osteoinductive biomaterials, the availability of bone active agents, capable of modulating fracture healing, actually represent the orthopaedic "weapons" to improve the surgical outcome and quality of life in patients with osteoporosis.
