Ten years of hip fractures in Italy: For the first time a decreasing trend in elderly women

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.

Hip osteoarthritis and osteoporosis: clinical and histomorphometric considerations.

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.

Heavy metals accumulation affects bone microarchitecture in osteoporotic patients

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.

Hip fractures in the elderly: the role of cortical bone

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.

Fracture healing in elderly patients: new challenges for antiosteoporotic drugs

Osteoporosis is a major public health concern, characterized by low bone mass and structural deterioration of bone tissue, leading to bone fragility and an increased susceptibility to fracture. Fracture repair progresses through different pathways, striking a balance between bone formation and bone remodeling mechanisms. Conventionally, fracture repair is divided into defined stages, each characterized by a specific set of cellular and molecular events. In postmenopausal women and elderly patients, bone healing rates are conditioned by cellular and molecular alterations to bone tissue that result in a progressive deterioration of fracture healing ability. In addition, in elderly patients, comorbidities and drugs therapies may also affect fracture healing. For this reason, pharmacological research is now focused on the possible use of antiosteoporotic drugs to promote bone healing in frail patients.

Clinical guidelines for the prevention and treatment of osteoporosis: summary statements and recommendations from the Italian Society for Orthopaedics and Traumatology

AbstractBackground The Italian Society for Orthopaedics and Traumatology conceived this guidance—which is primarily addressed to Italian orthopedic surgeons, but should also prove useful to other bone specialists and to general practitioners—in order to improve the diagnosis, prevention, and treatment of osteoporosis and its consequences.Materials and methodsLiterature reviews by a multidisciplinary team.ResultsThe following topics are covered: the role of instrumental, metabolic, and genetic evaluations in the diagnosis of osteoporosis; appraisal of the risk of fracture and thresholds for intervention; general strategies for the prevention and treatment of osteoporosis (primary and secondary prevention); the pharmacologic treatment of osteoporosis; the setting and implementation of fracture liaison services for tertiary prevention. Grade A, B, and C recommendations are provided based on the main levels of evidence (1–3). Toolboxes for everyday clinical practice are provided.ConclusionsThe first up-to-date Italian guidelines for the primary, secondary, and tertiary prevention of osteoporosis and osteoporotic fractures are presented.

Total hip arthroplasty revision in elderly patients

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.

Can Educational Interventions Improve Osteoporotic Women's Adherence to Treatment? A Literature Review.

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.

Surgical Therapy: Vertebro-Cifoplastic: – Pros and Cons

Vertebral compression fractures (VCFs) are the most common complication of osteoporosis. They result in significant mortality and morbidity and prolonged pain for patients. Vertebroplasty (PVP) and kyphoplasty (PKP) have recently been introduced for the treatment of osteoporotic patients who have prolonged pain following VCFs not responding to conservative treatment. Both procedures are based on the injection of a bone cement, usually polymethyl methacrylate (PMMA), into the fractured vertebra for the mechanical stabilization of VCFs and for pain relief. These procedures may be useful for osteoporotic patients who have prolonged pain following acute vertebral fracture and seem to determine a rapid and sustained pain relief with a better quality of life. Short-term complications, mainly the result of leakage extravasation of cement, include increased pain and damage from heat or pressure to the spinal cord or nerve roots as well as embolism problem. Proper patient selection and good technique should minimize complications, but, rarely, open surgery is needed. Long-term benfits have not yet been shown but potentially include prevention of recurrent pain at the treated level(s) with both procedures and with kyphoplasty restoration of height loss and spinal deformity, an improvement in level of function, and avoidance of chronic pain and restriction of internal organs. Controlled trials are needed to determine both short-term and long-term safety and efficacy of vertebroplasty and kyphoplasty.

Inquadramento del paziente fragile: dalla scienza di base alla clinica

The ageing of the population leads to an increase in the incidence of chronic-degenerative diseases such as osteoporosis. It causes macro- and microarchitectural alterations with a consequent risk of falling and fracture. The progressive subversion of the muscular structure typical of osteoporosis-related sarcopoenia contributes to the “frailty syndrome” that often affects elderly patients.
