Strategies for treatment to prevent fragility fractures in postmenopausal women.
The objective of treatment of osteoporosis is to decrease the risk of fractures in patients at high risk for a first or subsequent fracture. The efficacy of treatment will depend on the efficiency and level of implementation of clinical case finding to select patients at risk, the results of additional investigations, the efficacy, tolerance and safety of medical intervention and the adherence to treatment during follow-up. Each of these steps is critical in treatment in daily practice. Failure to consider one or another step can result in suboptimal fracture prevention or overtreatment. The aim of case finding is to identify patients for treatment, who have disease characteristics of patients in whom fracture prevention has been demonstrated in randomised controlled trials (RCTs). These include patients with a low-trauma hip or vertebral fracture, with a low bone mineral density (BMD) or with a high risk of fracture based on the presence of clinical risk factors (CRFs) for osteoporosis and fractures such as included in the FRAX case-finding algorithm, with or without BMD. Case finding starts clinically, with systematic or opportunistic doctor- and/or patient-driven evaluation for the presence of CRFs, but its implementation is low. Further investigations aim to assess the risk of fracture(s) and to have baseline measurements for the subsequent monitoring of treatment, to exclude diseases that mimic osteoporosis, to identify the cause of osteoporosis and contributory factors and to select the most appropriate treatment. Medical intervention consists of providing information about osteoporosis to the patient, lifestyle advice, optimalisation of calcium intake and vitamin D status, fall prevention to reduce fall risk, correction of reversible contributors to secondary osteoporosis and a wide array of drugs for prevention of a first or subsequent vertebral, hip and non-vertebral, non-hip fracture. Drug treatment is based on manipulation of bone remodelling by inhibiting bone resorption (bisphosphonates, selective oestrogen-receptor modulator (SERMs), calcitonin), stimulating bone formation (parathyroid hormone) or mixed effects (strontium ranelate). Follow-up allows to check tolerance and safety, to optimise adherence and to decide about adequacy of response, duration and switching of therapy.
