Osteoarthritis (OA) and osteoporosis (OP) are two diseases characterized by the alteration of bone quality, that affect mainly elderly people reducing their quality of life. Although an inverse relationship between has been shown by some studies, other reports supported the co-existence of these pathologies. In this study we combined clinical and structural features to clarify the relationship between OA and OP.Among all the patients who underwent a tota...

This study is focused on the effects of the synergic use of vitamins D and K on human osteoblasts primary cultures derived from osteoporotic and normal patients. The aim of this work is the evaluation of the different cellular behaviour in response to the lipophilic vitamins stimulation. We included 20 osteoporotic and 20 control patients in age between 35 and 50 and in age between 55 and 85. All patients gave informed consent for using bone samples as a source of bone cells. ...

Background and objective: Data concerning the incidence of fractures in Italy have been displayed since year 2000 by analysing hospital discharge records (HDRs). However, the influence of seasonal and environmental factors on fracture events in the Italian population has not yet been assessed.Methods: We have analyzed HDRs for primary diagnosis of hip, vertebral, forearm, humeral and knee fractures in Italy from year 2007 to 2009. Inferential statistics ...

We studied changes in intracellular Ca2+ concentration in bone cell cultures obtained from human subjects with osteoporosis and osteoarthritis, to evaluate differences between these patients and healthy subjects. We enrolled 36 patients: 12 undergoing primary total hip arthroplasty for osteoporotic femoral fractures (group A, mean age range 57–80), 12 for hip osteoarthritis (group B, mean age range 57–80), and 12 healthy subjects who suffered a high-energy...

Introduction: Age-related bone diseases, such as osteoarthritis (OA) and osteoporosis (OP), are strongly associated with sarcopenia and muscle fiber atrophy. Potential mechanisms involved in the reduction of skeletal muscle mass during sarcopenia converge on the failure of satellite cells in replacing and repairing damaged muscle fibers. Myostatin and bone morphogenetic proteins (BMPs) are molecules able to regulate muscle mass homeostasis by activating satellite stem cells [4...

Osteoarthritis and osteoporosis are two elderly conditions characterized by two different pathophysiological mechanisms. In patients with chronic kidney disease (CKD), there is a metabolic impairment of the muscular-skeletal tissue. The aim of our study is to evaluate the biochemical and morphostructural alterations in different states of CKD in patients with osteoarthritis or hip fracture.We evaluated all patients undergoing hip replacement surgery from...

Objectives: We aimed to evaluate 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 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 3-year period (2007–2009), presenting data per five-year age groups, ...
