Abstract
Osteoporosis is the most common metabolic bone disease in the USA and the world. It is a subclinical condition until complicated by fracture(s). These fractures place an enormous medical and personal burden on individuals who suffer from them and take a significant economic toll. Any new fracture in an adult aged 50 years or older signifies imminent elevated risk for subsequent fractures, particularly in the year following the initial fracture. What a patient perceives as an unfortunate accident may be seen as a sentinel event indicative of bone fragility and increased future fracture risk even when the result of considerable trauma. Clinical or subclinical vertebral fractures, the most common type of osteoporotic fractures, are associated with a 5-fold increased risk for additional vertebral fractures and a 2- to 3-fold increased risk for fractures at other sites. Untreated osteoporosis can lead to a vicious cycle of recurrent fracture(s), often resulting in disability and premature death. In appropriate patients, treatment with effective antifracture medication prevents fractures and improves outcomes. Primary care providers and medical specialists are critical gatekeepers who can identify fractures and initiate proven osteoporosis interventions. Osteoporosis detection, diagnosis, and treatment should be routine practice in all adult healthcare settings. The Bone Health and Osteoporosis Foundation (BHOF) - formerly the National Osteoporosis Foundation - first published the Clinician's Guide in 1999 to provide accurate information on osteoporosis prevention and treatment. Since that time, significant improvements have been made in diagnostic technologies and treatments for osteoporosis. Despite these advances, a disturbing gap persists in patient care. At-risk patients are often not screened to establish fracture probability and not educated about fracture prevention. Most concerning, the majority of highest risk women and men who have a fracture(s) are not diagnosed and do not receive effective, FDA-approved therapies. Even those prescribed appropriate therapy are unlikely to take the medication as prescribed. The Clinician's Guide offers concise recommendations regarding prevention, risk assessment, diagnosis, and treatment of osteoporosis in postmenopausal women and men aged 50 years and older. It includes indications for bone densitometry as well as fracture risk thresholds for pharmacologic intervention. Current medications build bone and/or decrease bone breakdown and dramatically reduce incident fractures. All antifracture therapeutics treat but do not cure the disease. Skeletal deterioration resumes sooner or later when a medication is discontinued-sooner for nonbisphosphonates and later for bisphosphonates. Even if normal BMD is achieved, osteoporosis and elevated risk for fracture are still present. The diagnosis of osteoporosis persists even if subsequent DXA T-scores are above - 2.5. Ongoing monitoring and strategic interventions will be necessary if fractures are to be avoided. In addition to pharmacotherapy, adequate intake of calcium and vitamin D, avoidance of smoking and excessive alcohol intake, weight-bearing and resistance-training exercise, and fall prevention are included in the fracture prevention armamentarium. Where possible, recommendations in this guide are based on evidence from RCTs; however, relevant published data and guidance from expert clinical experience provides the basis for recommendations in those areas where RCT evidence is currently deficient or not applicable to the many osteoporosis patients not considered for RCT participation due to age and morbidity.

Abstract
Objective: The development of these guidelines is sponsored by the American Association of Clinical Endocrinologists (AACE) Board of Directors and American College of Endocrinology (ACE) Board of Trustees and adheres with published AACE protocols for the standardized production of clinical practice guidelines (CPGs). Methods: Recommendations are based on diligent reviews of the clinical evidence with transparent incorporation of subjective factors, according to established AACE/ACE guidelines for guidelines protocols. Results: The Executive Summary of this 2020 updated guideline contains 52 recommendations: 21 Grade A (40%), 24 Grade B (46%), 7 Grade C (14%), and no Grade D (0%). These detailed, evidence-based recommendations allow for nuance-based clinical decision-making that addresses multiple aspects of real-world care of patients. The evidence base presented in the subsequent Appendix provides relevant supporting information for the Executive Summary recommendations. This update contains 368 citations: 123 (33.5%) evidence level (EL) 1 (highest), 132 (36%) EL 2 (intermediate), 20 (5.5%) EL 3 (weak), and 93 (25%) EL 4 (lowest). New or updated topics in this CPG include: clarification of the diagnosis of osteoporosis, stratification of the patient according to high-risk and very-high-risk features, a new dual-action therapy option, and transitions from therapeutic options. Conclusion: This guideline is a practical tool for endocrinologists, physicians in general, regulatory bodies, health-related organizations, and interested laypersons regarding the diagnosis, evaluation, and treatment of post-menopausal osteoporosis.

Abstract
ABSTRACTObjectiveAcutely painful osteoporotic vertebral compression fractures are associated with hospitalization and mortality in older adults. Calcitonin may be an alternative to opioid or nonopioid analgesia for treating acute compression fracture pain in emergency and primary care settings. This review summarizes pain, function, and adverse events associated with calcitonin.MethodsWe searched MEDLINE, EMBASE, The Cochrane Library, clinical trials registries, and reference lists of included studies. Eligible studies evaluated the effect of synthetic calcitonins (salmon, eel, and human) on pain scores in adults ≥60 years old with a recent atraumatic compression fracture. Two reviewers screened studies, extracted data, and allocated bias in duplicate. A random effects meta-analysis evaluated standard mean difference (SMD) and heterogeneity (I2).ResultsOf 1,198 articles screened, 11 were included (9 in the meta-analysis). Treatment lasted from 14 days to 6 months. Pain was lower in the salmon calcitonin group (100–200 IU IM or NAS, daily) than the control group with high certainty of evidence at week 1 (SMD, -1.54; 95% confidence interval [CI], -2.02 – -1.06; I2 = 52%), representing a number needed to treat of two. The analgesic efficacy of salmon calcitonin at 4 weeks was unclear due to substantial heterogeneity. There was low certainty evidence that calcitonin did not increase the overall risk of adverse events, including nausea and vomiting (risk ratio, 2.10; 95% CI, 0.87–5.08; I2 = 47%).ConclusionsCalcitonin is beneficial and appears safe for treating acute pain associated with compression fractures. Further studies may improve the certainty of evidence.

Abstract
Background Primary osteoporosis is a common disease among postmenopausal women and the elderly; low back pain is the most typical clinical manifestation an is the primary reason for a clinic visit, and directly affects patients’ quality of life. Anti-osteoporosis medications have undesirable side effects, and many kinds of special traditional Chinese moxibustion methods have been widely used in the clinical treatment of osteoporosis low back pain. The purpose of this study was to observe whether thunder-fire moxibustion therapy, compared to calcium supplements alone, can ease osteoporosis low back pain, improve quality of life, and reduce tension of the multifidus. Material/Methods Sixty-three eligible patients were enrolled in the study (7 of these patients did not finish the study and are not included in analysis). Participants were randomly divided into 2 groups: a moxibustion group that received calcium carbonate D3 and thunder-fire moxibustion therapy, and a control group that received calcium carbonate D3 only. Level of pain experienced, assessed using the visual analogue scale (VAS), and quality of life (SF-36) were measured pre-treatment, at the end of 4 weeks of treatment, and at a 1-month post-treatment evaluation. Changes in values of Young’s modulus of the multifidus were also collected before and after treatment. Results After 4 weeks of treatment and at 1 month after treatment had ended, low back pain in both groups was reduced relative to pre-treatment levels. The moxibustion group was significantly improved at BP, GH, SF, and MH dimensions compared to pre-treatment levels. The control group improved in BP dimensions, but not to the same extent as the moxibustion group. Similarly, after treatment for 4 weeks with moxibustion, multifidus tension was significantly reduced. Conclusions Thunder-fire moxibustion is an effective method for treating low back pain due to primary osteoporosis.

Abstract
STUDY DESIGN Narrative review. OBJECTIVE Despite the numerous treatment options for vertebral compression fractures, a consensus opinion for the management of patients with these factures has not been established. This review is meant to provide an up-to-date overview of the most common treatment strategies for compression fractures and to suggest possible routes for the development of clearer treatment guidelines. METHODS A comprehensive database search of PubMed was performed. All results from the past 30 years were obtained and evaluated based on title and abstract. The full length of relevant studies was analyzed for level of evidence, and the strongest studies were used in this review. RESULTS The major treatment strategies for patients with compression fractures are conservative pain management and vertebral augmentation. Despite potential adverse effects, medical management, including nonsteroidal anti-inflammatory drugs, calcitonin, teriparatide, and bisphosphonates, remains the first-line therapy for patients. Evidence suggests that vertebral augmentation, especially some of the newer procedures, have the potential to dramatically reduce pain and improve quality of life. At this time, balloon-assisted kyphoplasty is the procedure with the most evidence of support. CONCLUSIONS Based on current literature, it is evident that there is a lack of standard of care for patients with vertebral compression fractures, which is either due to lack of evidence that a procedure is successful or due to serious adverse effects encountered with prolonged treatment. For a consensus to be reached, prospective clinical trials need to be formulated with potential new biomarkers to assess efficacy of treatment strategies.

Abstract
Management of spine surgery patients with osteoporosis is challenging because of the difficulty of instrumenting and the potential complications, including nonunion and adjacent level fractures. Treatment of this patient population should involve a multidisciplinary approach including the spine surgeon, primary care physician, endocrinologist, and physical therapist. Indication for preoperative treatment before spinal fusion surgery is unclear. All patients should receive calcium and vitamin D. Hormone replacement therapy, including estrogen or selective estrogen receptor modulators, should be considered for elderly female patients with decreased bone mass. Bisphosphonates or intermittent parathyroid hormone are reserved for those with significant bone loss in the spine. Pretreatment with antiresorption medications affect bone remodeling, which is a vital part of graft incorporation and fusion. Although there have been numerous animal studies, there is limited clinical evidence. Accordingly, surgery should be delayed, if possible, to treat the osteoporosis before the intervention. Treatment may include bisphosphonates, as well as newer agents, such as recombinant parathyroid hormone. Further clinical data are needed to understand the relative advantages/disadvantage of antiresorptive vs anabolic agents, as well as the impact of administration of these medications before vs after fusion surgery. Future clinical studies will enable better understanding of the impact of current therapies on biomechanics and fusion outcomes in this unique and increasingly prevalent patient population.

Abstract
Background: Physical activity and mental health could be affected by osteoporosis and various therapeutic options such as calcitonin may influence Quality Of Life (QOL) of these patients with Low Bone Density (LBD). Objectives: This study aimed to evaluate the effect of nasal calcitonin on QOL in post menopause women with LBD. Patients and Methods: This clinical trial study was performed on one hundred and fifteen menopause women with LBD less than 1 SD in Bone Mineral Densitometry (BMD) referred to Baqiyatallah Hospital in Tehran, Iran, during 2009 - 2010. They were assigned to receive 200 IU calcitonin nasal spray along with calcium (1000 mg) and vitamin D (400 IU) for 6 months. Quality of life was assessed by Short-Form 36 (SF-36) questionnaire (Persian-validated version). Results: The mean age (± SD) of the participants was 58.75 ± 8.15 years. Intranasal spray of calcitonin increased QOL scores significantly (88.05 ± 15.63 vs. 92.15 ± 13.22, P value = 0.000). Bone mineral density of spine was increased from 0.834 ± 0.11 to 0.12 ± 0.852 and this difference in BMD of lumbar spine was statistically significant (P value: 0.003) but not significant in femur’s BMD (P value = 0.061). In comparison with BMD indexes, The QOL scores especially Mental Health domain changes had only a significant correlation with the changes of total T score in BMD (P = 0.031, Coefficient Correlation = 0.248). Conclusions: It seems that nasal spray of calcitonin can effectively improve QOL of women with LBD and QOL changes were not influenced by clinical or para-clinical alteration. Mental health domain must be more considered in further studies as a predicting domain for Health-Related Quality of Life (HR-QOL) changes.

Abstract
Calcitonin has been reported to reduce acute and chronic back pain in osteoporotic patients. The additive effect of calcitonin with a bisphosphonate on chronic back pain remains unclear. The purpose of this study was to evaluate the effect of combining elcatonin (eel calcitonin) with risedronate for patients with chronic back pain. Forty-five postmenopausal women diagnosed as having osteoporosis with chronic back pain persisting for more than 3 months, after excluding women with fresh vertebral fractures within the last 6 months, were randomly allocated to a risedronate group (risedronate alone, n = 22) and a combined group (risedronate and elcatonin, n = 23). The study period was 6 months. Pain was evaluated with a visual analogue scale (VAS) and the Roland-Morris questionnaire (RDQ). Back extensor strength, bone mineral density, and quality of life on the SF-36 and the Japanese osteoporosis quality of life score were also evaluated. Significant improvements were found in the combined group for VAS at final follow-up compared with baseline and 3 months, mental health status on the SF-36, and JOQOL domains for back pain and general health. The JOQOL domain for back pain improved significantly, but no change was found in the VAS or other domains in the risedronate group. Bone mineral density increased significantly in the two groups, but no significant difference was found between the groups. Back extensor strength did not change in both groups. In conclusion, the use of elcatonin in addition to risedronate for more than 3 months reduced chronic back pain. The additional therapy of risedronate with elcatonin may be a useful and practical choice for the treatment of osteoporosis with chronic back pain persisting more than 3 months.

Abstract
Vertebral collapse is a common fracture associated with osteoporosis. Subsequent pain may be severe and often requires medications and bed rest. Several studies have suggested the use of calcitonin for the treatment of fracture pain. We sought to determine the analgesic efficacy of calcitonin for acute and chronic pain of osteoporotic vertebral compression fractures (OVCF). We searched for randomized, placebo, and controlled trials that evaluated the analgesic efficacy of calcitonin for pain attributable to OVCFs. We performed meta-analyses to calculate standardized mean differences (SMDs) using a fixed or random effects model. The combined results from 13 trials (n = 589) determined that calcitonin significantly reduced the severity of acute pain in recent OVCFs. Pain at rest was reduced by week 1 [mean difference (MD) = -3.39, 95% confidence interval (CI) = -4.02 to -2.76), with continued improvement through 4 weeks. At week 4, the difference in pain scores with mobility was even greater (SMD = -5.99, 95% CI = -6.78 to -5.19). For patients with chronic pain, there was no statistical difference between groups while at rest; there was a small, statistically significant difference between groups while mobile at 6 months (SMD = 0.49, 95% CI = -0.85 to -0.13, p = 0.008). Side effects were mild, with enteric disturbances and flushing reported most frequently. Although calcitonin has proven efficacy in the management of acute back pain associated with a recent OVCF, there is no convincing evidence to support the use of calcitonin for chronic pain associated with older fractures of the same origin.

Abstract
Back and knee pain is a widespread health problem and a serious threat to the quality of life (QOL) in middle-aged and older adults, as it frequently accompanies osteoporosis and osteoarthritis. In order to compare the effects of elcatonin and risedronate on such pain, 20 units of elcatonin was intramuscularly injected to 18 patients, and 5 mg of risedronate was orally administered daily to 20 others with similar backgrounds. Exercise-induced pain was analyzed by measuring the fall of skin impedance by electroalgometry (EAM), and subjective pain was recorded by a visual rating system (VRS) on a scale of 0 (no pain) to 100 (unbearable pain). In patients treated with elcatonin, the mean EAM-estimated pain was significantly reduced after 4, 5 and 6 months of treatment, and the VRS score after 3, 5 and 6 months, indicating a significant analgesic effect. In the risedronate group, however, improvement was less remarkable. Two-way analysis of variance using pain as a dependent variable and treatment group and time as independent variables revealed a significantly greater effect of elcatonin over risedronate on both the EAM and VRS scores, and the influence of treatment time on pain was indistinguishable between the two treatment groups. Effect of exercise load on pain was less on knee load than knee and spine load and spine load, but indistinguishable between the two groups. Changes in QOL were evaluated by the SF-36 system. Norm-based scoring showed significant improvements in 3 of 4 categories for elcatonin and in 2 of 4 for risedronate, suggesting comparable effects on the physical aspects of QOL, whereas responses to emotionally and socially directed questions indicated significant improvements in all 4 categories for risedronate, but none for elcatonin, suggesting a more physical than emotional component in elcatonin effects compared to risedronate.

Abstract
This clinical practice guideline is based on a series of systematic reviews of published studies on the treatment of symptomatic osteoporotic spinal compression fractures. Of 11 recommendations, one is strong; one, moderate; three, weak; and six, inconclusive. The strong recommendation is against the use of vertebroplasty to treat the fractures; the moderate recommendation is for the use of calcitonin for 4 weeks following the onset of fracture. The weak recommendations address the use of ibandronate and strontium ranelate to prevent additional symptomatic fractures, the use of L2 nerve root blocks to treat the pain associated with L3 or L4 fractures, and the use of kyphoplasty to treat symptomatic fractures in patients who are neurologically intact.

Abstract
Pharmacologic osteoporosis therapy, particularly anti-resorptives, is recommended in postmenopausal women with clinical risk factors for fracture. Treatment decisions should be made based on the relative benefit-risk profile in different patient populations. Emerging options [e.g., selective estrogen receptor modulators (SERMs) and denosumab] may hold promise for providing protection from bone loss and for fracture risk reduction.Osteoporosis, the most common clinical disorder of bone metabolism, is characterized by low bone mineral density, deterioration of microarchitecture, and a consequent increase in bone fragility and risk of fracture. Pharmacologic therapy is recommended in postmenopausal women with clinical risk factors for fracture and includes anti-resorptive agents such as bisphosphonates, hormone therapy, SERMs, and calcitonin. The anabolic agent teriparatide (parathyroid hormone) is usually reserved for high-risk patients or those with glucocorticoid-induced osteoporosis. Strontium ranelate, available outside the USA, has both anti-resorptive and anabolic properties. Supplementation with calcium and vitamin D is recommended for all women aged 50 years and older. Bisphosphonates are often considered first-line therapy for osteoporosis and have the largest base of clinical trial data showing efficacy for global fracture risk reduction. Low-dose hormone therapy is appropriate for younger women who are experiencing other menopausal symptoms. In women for whom bisphosphonates are not appropriate or not tolerated or in younger postmenopausal women who have a low risk for hip fracture, SERMs are a suitable treatment option. Calcitonin is designated for patients who are unable or unwilling to tolerate other osteoporosis agents. Emerging options, including newer SERMs (e.g., bazedoxifene and lasofoxifene) and the monoclonal antibody denosumab, may hold promise for providing protection from bone loss and for fracture risk reduction. Because no single agent is appropriate for all patients, treatment decisions should be made on an individual basis, taking into account the relative benefits and risks in different patient populations.

Abstract
IMPORTANCE OF THE FIELD Osteoporosis is a slow progressive disease with develops over decades, and where intervention is needed for an extended number of years. This highlights the need for safe intervention possibilities, which have sustained beneficial effects post-treatment. AREAS COVERED IN THIS REVIEW Articles on salmon calcitonin appearing on Pubmed from 1960 until today, with focus on a newly developed oral formulation showing increased exposure and efficacy compared with nasal formulation is reviewed. The second half focuses on long-term phenomena, such as bone quality and resolution effects. The final part discusses potential additional benefits of salmon calcitonin. WHAT THE READER WILL GAIN Insight into the clinical development of an orally formulated peptide, as well as a detailed understanding of why this approach could revive salmon calcitonin as a treatment for osteoporosis. TAKE HOME MESSAGE The oral formulation of salmon calcitonin provides additional benefits and increased efficacy on bone based on Phase I and II clinical trials data, as compared with the nasal formulation. Hence, the results on the ongoing Phase III fracture trial are awaited with great interest.

Abstract
The hydrogel system of poly(methacrylic acid-co-N-vinyl pyrrolidone) was evaluated for use as an oral delivery system for growth hormone and salmon calcitonin. These proteins were selected because of their therapeutic importance and the insight provided by evaluating the delivery of a therapeutic agent with a high molecular weight (growth hormone) and a drug with a high isoelectric point (salmon calcitonin). Growth hormone loading and release studies were performed for both P(MAA-co-NVP) and P(MAA-g-PEG). Loading efficiencies for the respective systems were 50.9 ± 1.8% and 57.8 ± 4.1%; weight incorporation of the protein was determined to be 3.5 ± 0.1% and 4.0 ± 0.3%. At pH 7.4, growth hormone release of 90% occurred within 45 min for P(MAA-co-NVP) microparticles; 90% release was not achieved with P(MAA-g-PEG) microparticles until 180 min. At pH 1.2, no release occurred from P(MAA-co-NVP) microparticles but 10% release occurred from P(MAA-g-PEG) microparticles. Salmon calcitonin loading and release were shown to be affected by the negative charges of deprotonated MAA; for systems with monomer molar feed ratios of 4:1, 1:1 and 1:4 MAA:NVP, loading efficiencies were determined to be 70.6 ± 3.0%, 25.3 ± 1.2%, and 1.6 ± 1.3%. Salmon calcitonin release was minimal from the copolymer with 4:1 MAA:NVP monomer feed at pH 7.4. The release improved when the pH was raised above physiological levels. These studies confirmed that P(MAA-co-NVP) was an effective oral delivery system for high molecular weight drugs, but improvements are needed before the system could be utilized for high isoelectric point therapeutic delivery.

Abstract
OBJECTIVE To update the evidence-based position statement published by The North American Menopause Society (NAMS) in 2006 regarding the management of osteoporosis in postmenopausal women. METHODS NAMS followed the general principles established for evidence-based guidelines to create this updated document. A panel of clinicians and researchers expert in the field of metabolic bone diseases and/or women's health was enlisted to review the 2006 NAMS position statement, compile supporting statements, and reach consensus on recommendations. The panel's recommendations were reviewed and approved by the NAMS Board of Trustees. RESULTS Osteoporosis, which is especially prevalent among older postmenopausal women, increases the risk of fractures. Hip and spine fractures are associated with particularly high morbidity and mortality in this population. Given the health implications of osteoporotic fractures, the primary goal of osteoporosis therapy is to prevent fractures, which is accomplished by slowing or stopping bone loss, maintaining bone strength, and minimizing or eliminating factors that may contribute to fractures. The evaluation of postmenopausal women for osteoporosis risk requires a medical history, physical examination, and diagnostic tests. Major risk factors for postmenopausal osteoporosis (as defined by bone mineral density) include advanced age, genetics, lifestyle factors (such as low calcium and vitamin D intake, smoking), thinness, and menopause status. The most common risk factors for osteoporotic fracture are advanced age, low bone mineral density, and previous fracture as an adult. Management focuses first on nonpharmacologic measures, such as a balanced diet, adequate calcium and vitamin D intake, adequate exercise, smoking cessation, avoidance of excessive alcohol intake, and fall prevention. If pharmacologic therapy is indicated, government-approved options are bisphosphonates, selective estrogen-receptor modulators, parathyroid hormone, estrogens, and calcitonin. CONCLUSIONS Management strategies for postmenopausal women involve identifying those at risk for fracture, followed by instituting measures that focus on reducing modifiable risk factors through dietary and lifestyle changes and, if indicated, pharmacologic therapy.

Abstract
It is assumed that there are systemic changes in mineral metabolism during fracture healing that may cause a predisposition to sequential fractures in osteoporotic patients who suffered from previous fractures. Initial therapies for patients with osteoporotic fractures are important to prevent disabilities in daily life consequent to bone and muscle atrophies, and sequential fractures, although systemic and local bone metabolism during fracture healing have not been well understood. We evaluated the effects of bone injury and elcatonin injection as an initial therapy on systemic and local bone turnover and bone wound healing. Two drill holes were made in the diaphysis of the left femur and tibia of 12-week-old male C57BL/6J mice. They were treated with three doses of elcatonin or a vehicle thrice a week until the end of the 28-day experiment. Urinary crosslinked C-telopeptide of type I collagen (CTX) increased and the bone mineral densities (BMDs) in the lumbar vertebrae decreased in the vehicle-treated mice. Elcatonin injection prevented increases in urinary CTX and reduction of the BMDs. In the noninjured femoral metaphysis, osteoclast surface increased until day 28, whereas elcatonin suppressed it. In the fracture site, elcatonin facilitated osteoblast proliferation and did not delay the healing of the bone defect. Bone injuries accelerated bone turnover systemically and locally, and the elcatonin injections suppressed the systemic acceleration of bone resorption without a delay of filling regenerated cortical bone in the bone defect.

Abstract
The combination of materials design and advances in nanotechnology has led to the development of new therapeutic protein delivery systems. The pulmonary, nasal, buccal and other routes have been investigated as delivery options for protein therapy, but none result in improved patient compliances and patient quality of life as the oral route. For the oral administration of these new systems, an understanding of protein transport is essential because of the dynamic nature of the gastrointestinal tract and the barriers to transport that exist.Models have been developed to describe the transport between the gastrointestinal lumen and the bloodstream, and laboratory techniques like cell culture provide a means to investigate the absorption and transport of many therapeutic agents. Biomaterials, including stimuli-sensitive complexation hydrogels, have been investigated as promising carriers for oral delivery. However, the need to develop models that accurately predict protein blood concentration as a function of the material structure and properties still exists.

Abstract
Osteoporosis is a systemic skeletal disease characterized by diminished bone mass and deterioration of bone microarchitecture, leading to increased fragility and subsequent increased fracture risk. Therapeutic measures therefore aim at reducing individual fracture risk. In Austria, the following drugs, all of which have been proven to reduce fracture risk, are currently registered for the treatment of postmenopausal osteoporosis: alendronate, risedronate, etidronate, ibandronate, raloxifene, teriparatide (1-34 PTH), 1-84 PTH, strontium ranelate and salmon calcitonin. Fluorides are still available, but their role in daily practice has become negligible. Currently, there is no evidence that a combination of two or more of these drugs could improve anti-fracture potency. However, treatment with PTH should be followed by the treatment with an anticatabolic drug such as bisphosphonates. Calcium and vitamin D constitute an important adjunct to any osteoporosis treatment.

Abstract
BACKGROUND Calcitonin is used as a treatment to reduce the blood calcium concentration in hypercalcemia and to improve bone mass in osteoporosis. An analgesic effect of calcitonin has been observed and reported in clinical situations. Ovariectomized (OVX) rats exhibit the same hormonal changes as observed in humans with osteoporosis and are an animal model of postmenopausal osteoporosis. The aim of this study to investigate antinociceptive effect of calcitonin in OVX rats using the immunohistochemical study. METHODS We assessed the antinociceptive effects of calcitonin in an ovariectomized (OVX) rat model, which exhibit osteoporosis and hyperalgesia, using the immunohistochemical method. Fifteen rats were ovariectomized bilaterally, and ten rats were received the same surgery expected for ovariectomy as a sham model. We used five groups: the OVX-CT (n = 5), the sham-CT (n = 5), and the OVX-CT-pcpa (n = 5) groups received calcitonin (CT: 4 U/kg/day), while OVX-vehi (n = 5) and the sham-vehi (n = 5) groups received vehicle subcutaneously 5 times a week for 4 weeks. The OVX-CT-pcpa-group was given traperitoneal injection of p-chlorophenylalanine (pcpa; an inhibitor of serotonin biosynthesis) (100 mg/kg/day) in the last 3 days of calcitonin injection. Two hours after 5% formalin (0.05 ml) subcutaneously into the hind paw, the L5 spinal cord were removed and the number of Fos-immunoreactive (ir) neurons were evaluated using the Mann-Whitney-U test. RESULTS The numbers of Fos-ir neurons in the OVX-CT and sham-CT groups were significantly less than in the OVX-vehi and sham-vehi groups, respectively (p = 0.0090, p = 0.0090). The number of Fos-ir neurons in the OVX-CT-pcpa-group was significantly more than that of the OVX-CT-group (p = 0.0283), which means pcpa inhibits calcitonin induced reduction of c-Fos production. CONCLUSION The results in this study demonstrated that 1) the increase of c-Fos might be related to hyperalgesia in OVX-rats. 2) Calcitonin has an antinociceptive effect in both OVX and sham rats. 3) The central serotonergic system is involved in the antinociceptive properties of calcitonin.

Abstract
Background Vertebroplasty is a promising but as yet unproven treatment for painful osteoporotic vertebral fractures. It involves radiographic-guided injection of various types of bone cement directly into the vertebral fracture site. Uncontrolled studies and two controlled quasi-experimental before-after studies comparing volunteers who were offered treatment to those who refused it, have suggested an early benefit including rapid pain relief and improved function. Conversely, several uncontrolled studies and one of the controlled before-after studies have also suggested that vertebroplasty may increase the risk of subsequent vertebral fractures, particularly in vertebrae adjacent to treated levels or if cement leakage into the adjacent disc has occurred. As yet, there are no completed randomised controlled trials of vertebroplasty for osteoporotic vertebral fractures. The aims of this participant and outcome assessor-blinded randomised placebo-controlled trial are to i) determine the short-term efficacy and safety (3 months) of vertebroplasty for alleviating pain and improving function for painful osteoporotic vertebral fractures; and ii) determine its medium to longer-term efficacy and safety, particularly the risk of further fracture over 2 years. Design A double-blind randomised controlled trial of 200 participants with one or two recent painful osteoporotic vertebral fractures. Participants will be stratified by duration of symptoms (< and ≥ 6 weeks), gender and treating radiologist and randomly allocated to either the treatment or placebo. Outcomes will be assessed at baseline, 1 week, 1, 3, 6, 12 and 24 months. Outcome measures include overall, night and rest pain on 10 cm visual analogue scales, quality of life measured by the Assessment of Quality of Life, Osteoporosis Quality of Life and EQ-5D questionnaires; participant perceived recovery on a 7-point ordinal scale ranging from 'a great deal worse' to 'a great deal better'; disability measured by the Roland-Morris Disability Questionnaire; timed 'Up and Go' test; and adverse effects. The presence of new fractures will be assessed by radiographs of the thoracic and lumbar spine performed at 12 and 24 months. Discussion The results of this trial will be of major international importance and findings will be immediately translatable into clinical practice.

Abstract
Salmon calcitonin, available as a therapeutic agent for more than 30 years, demonstrates clinical utility in the treatment of such metabolic bone diseases as osteoporosis and Paget's disease, and potentially in the treatment of osteoarthritis. This review considers the physiology and pharmacology of salmon calcitonin, the evidence based research demonstrating efficacy and safety of this medication in postmenopausal osteoporosis with potentially an effect on bone quality to explain its abilities to reduce the risk of spine fracture, the development of an oral salmon calcitonin preparation, and the therapeutic rationale for this preparation's chondroprotective effect in osteoarthritis.

Abstract
Back pain in the elderly is a complex chief complaint, because numerous life-threatening or disabling conditions may present with signs and symptoms similar to those of more benign disease processes. An understanding of the limitations of physical examination and history distinguishing dangerous from benign causes is essential to avoid misdiagnosis and patient morbidity or mortality. This article describes the presentation and evaluation of dangerous causes of back pain, including vascular catastrophes, spinal cord compression syndromes, and infectious diseases. Less emergent musculoskeletal injuries are discussed briefly.

Abstract
OBJECTIVES Patients in long-term care institutions (LTCI) are especially at risk for osteoporotic fractures owing to their lack of mobility, poor nutrition, and limited sun exposure. Previous reports have shown that osteoporosis is underdiagnosed and undertreated in LTCI despite the high incidence of osteoporotic fractures in these settings. This document has been developed to assist clinicians practicing in LTCI with the diagnosis and treatment of osteoporosis in their institutionalized patients. These proceedings offer an overview of the particular characteristics of patients at LTCI. Management strategies include both nonpharmacological and pharmacological interventions for the prevention and treatment of osteoporotic fractures in very frail older subjects. PARTICIPANTS This guide is an edited review of presentations and discussions held by specialists in osteoporosis in the elderly together with physicians and pharmacists practicing in LTCI in the province of Quebec. This symposium was held in Saint-Hyacinthe, Quebec on November 5, 2004. VALUES The value of a given diagnostic test or treatment option was determined based on the clinical experiences and opinions of the participants and a review of the literature from an evidence-based perspective. RECOMMENDATIONS All patients located at LTCI are at potential risk for osteoporotic fractures. Global interventions should include vitamin D, calcium, and a comprehensive exercise program. In patients who are at high risk for osteoporotic fractures or with previous fractures, pharmacological treatment should be started. VALIDATION These recommendations were approved during the final plenary of the symposium. All the prevailing opinions were summarized and included in this article.

Abstract
OBJECTIVE To update the evidence-based position statement published by The North American Menopause Society (NAMS) in 2002 regarding the management of osteoporosis in postmenopausal women. DESIGN NAMS followed the general principles established for evidence-based guidelines to create this updated document. A panel of clinicians and researchers expert in the field of metabolic bone diseases and/or women's health were enlisted to review the 2002 NAMS position statement, compile supporting statements, and reach consensus on recommendations. The panel's recommendations were reviewed and approved by the NAMS Board of Trustees. RESULTS Osteoporosis, whose prevalence is especially high among elderly postmenopausal women, increases the risk of fractures. Hip and spine fractures are associated with particularly high morbidity and mortality in this population. Given the health implications of osteoporotic fractures, the primary goal of osteoporosis therapy is to prevent fractures, which is accomplished by slowing or stopping bone loss, maintaining bone strength, and minimizing or eliminating factors that may contribute to fractures. The evaluation of postmenopausal women for osteoporosis risk requires a medical history, physical examination, and diagnostic tests. Major risk factors for postmenopausal osteoporosis (as defined by bone mineral density) include advanced age, genetics, lifestyle factors (such as low calcium and vitamin D intake, smoking), thinness, and menopause status. The most common risk factors for osteoporotic fracture are advanced age, low bone mineral density, and previous fracture as an adult. Management focuses first on nonpharmacologic measures, such as a balanced diet, adequate calcium and vitamin D intake, adequate exercise, smoking cessation, avoidance of excessive alcohol intake, and fall prevention. If pharmacologic therapy is indicated, government-approved options are bisphosphonates, a selective estrogen-receptor modulator, parathyroid hormone, estrogens, and calcitonin. CONCLUSIONS Management strategies for postmenopausal women involve identifying those at risk of low bone density and fracture, followed by instituting measures that focus on reducing modifiable risk factors through lifestyle changes and, if indicated, pharmacologic therapy.

Abstract
The purpose of this study was to evaluate the efficacy of calcitonin on beta-endorphin levels in female patients experiencing back pain associated with postmenopausal osteoporosis. The secondary purpose was to assess the pain and quality of life in these patients. There were 30 patients with a mean age of 58.2+/-5.4 years in the treatment group and 26 patients with a mean age of 58.8+/-5.2 years in the placebo group in this randomized, placebo-controlled study. The patients subcutaneously received 100 IU salmon calcitonin or placebo injections and 1,000 mg elementary calcium for 2 weeks. Baseline plasma beta-endorphin levels were measured and repeated after 2 weeks. Patients' pain and quality of life (QOL) were evaluated by using the Visual Analogue Scale, Modified Face Scale, Beck Depression Index, and Nottingham Health Profile. Patients' global assessment of disease activity was also performed at baseline and at the end of the first and second week. We found that plasma beta-endorphin levels in the treatment group were significantly higher than the placebo group at the end of the second week (p<0.001). Although pain and QOL scores were improved at the end of the second week in both groups (p<0.05), the improvement in the treatment group was more significant when compared with the placebo group (p<0.05). Therefore, calcitonin is an analgesic agent, as it increases the plasma beta-endorphin levels in patients with postmenopausal osteoporosis, which consequently improves QOL.

Abstract
Vertebral collapse is one of the most common fractures associated with osteoporosis. The subsequent back pain is severe and often requires medications, bed rest and hospitalization to control pain and improve mobilization. The purpose of this systematic review was to assess the effects of calcitonin versus placebo for the treatment of acute pain in patients sustaining stable, recent, osteoporotic vertebral compression fractures. MEDLINE (1966-2003), EMBASE (1980-2003), Cochrane Controlled Trial Registry (2003, volume 3), other databases, and conference proceedings were searched for relevant research. Primary study authors and the pharmaceutical manufacturer were contacted, and bibliographies of relevant papers were hand-searched. Randomized, double-blind, placebo-controlled trials comparing calcitonin versus placebo for the acute pain of recent osteoporotic vertebral compression fractures were included. Two reviewers extracted data, performed numeric calculations and extrapolated graphical data independently. The combined results from five randomized controlled trials, involving 246 patients, determined that calcitonin significantly reduced the severity of pain using a visual analogue scale following diagnosis. Pain at rest was reduced as early as 1 week into treatment (weighted mean difference [WMD] =3.08; 95% confidence interval [CI]: 2.64, 3.52) and this effect continued weekly to 4 weeks (WMD =4.03; 95% CI: 3.70, 4.35). A similar pattern was seen for pain scores associated with sitting, standing, and walking. Side effects were gastrointestinal, minor and often self-limited. Calcitonin appears to be effective in the management of acute pain associated with acute osteoporotic vertebral compression fractures by shortening time to mobilization.

Abstract
The aim of this study was to investigate the effect of nasal calcitonin on chronic back pain and disability attributed to osteoporosis. The study design involved three groups of osteoporotic postmenopausal women suffering from chronic back pain. Group I consisted of 40 women with vertebral fractures, group II of 30 women with degenerative disorders and group III of 40 patients with non specific chronic back pain and without abnormality on plain X-rays. Pain intensity was measured using a numerical rating scale (NRS) and disability due to back pain was measured using the Oswestry disability questionnaire. The patients were randomly assigned to receive, for three months, either 200 IU intranasal salmon calcitonin and 1,000 mg of oral calcium daily (groups IA, IIA, IIIA) or 1,000 mg of oral calcium daily (groups IB, IIB, IIIB). Repeated measures ANOVA showed that there were no significant time, group or interaction effects for pain intensity and disability in any of the groups studied. Mean Oswestry and NRS scores were reduced during the follow-up period in the groups IA, IIIA, but the differences between the two time points were not statistically significant. Intranasal calcitonin has no effect on chronic back pain intensity and functional capacity of osteoporotic women regardless of the presence of fractures, degenerative disorders or chronic back pain of non-specific etiology.

Abstract
OBJECTIVE The increasing rate of hip fractures is giving rise to a number of socio-economic problems for the aging community. In addition to being unable to resume their previous living habits, many patients fail to achieve full functional recovery after the fractures. Total hip arthroplasty (THA) is a successful operation for the majority of patients with all forms of hip fractures, being performed increasingly often throughout the world. Revision rates for THA range up to 20% per year. Aseptic loosening is the reason for 75% of the revisions. An additional problem post-THA is the rate of heterotopic soft tissue calcification after THA, resulting in severely impaired function, pain, and a reduced range of hip movement. SUBJECTS In an open study, 37 women who had undergone cementless THA after accidental hip fractures were treated twice daily with 200 IU of salmon calcitonin nasal spray for 12 months. Simultaneously the patients received one bag of 1,000 mg calcium plus 880 IU vitamin D daily throughout the treatment period of 1 year. A parallel group of 38 women with a similar clinical status in terms of hip fractures and cementless THA were treated with only one bag of 1,000 mg calcium plus 880 IU vitamin D daily through the treatment period. RESULTS The results of this 12-month clinical trial show that 200 IU of salmon calcitonin nasal spray per day significantly improves the clinical outcome of postmenopausal elderly women following THA. Treatment with a salmon calcitonin nasal spray significantly reduces bone turnover, loss of bone density, and pain. The functional status of the patients was improved and the risk of falling reduced by rehabilitation during the observation period of 12 months. Additionally, calcitonin promoted the repair of hip fractures and was associated with a significantly lesser rate of refractures as well as periprosthetic ossifications. CONCLUSION The increasing revision rate for THA during the first year and the patient's problem of resuming their previous living habits are the main foci of our study. Calcitonin nasal spray seems to cause few side effects. The additive treatment appears to improve the clinical outcome of THA in elderly postmenopausal women.

Abstract
Osteoporosis is the most prevalent metabolic bone disease and is characterized by diminished bone strength predisposing to an increased risk of fracture. Its incidence is particularly high in postmenopausal women but it can also affect other groups, such as men and patients receiving corticosteroid therapy. Calcitonin is a naturally occurring peptide which acts via specific receptors to strongly inhibit osteoclast function. It has been used in the treatment of osteoporosis for many years. Historically, calcitonin was administered as a parenteral injection, but the intranasal formulation is now the most widely used because of its improved tolerability. New approaches are currently being investigated to enhance the bioavailability and effects of calcitonin, including oral, pulmonary, and transdermal routes of administration, and novel allosteric activators of the calcitonin receptor. Several controlled trials have reported that calcitonin stabilizes and in some cases produces a short-term increase in bone density at the lumbar spine level. The most relevant clinical trial to evaluate the effect of calcitonin in the prevention of fractures was the Prevent Recurrence of Osteoporotic Fractures (PROOF) study, a 5-year double-blind, randomized, placebo-controlled trial showing that salmon calcitonin nasal spray at a dosage of 200 IU/day can reduce the risk of vertebral osteoporotic fractures by 33% (relative risk [RR] = 0.67; 95% CI 0.47, 0.97; p = 0.03). However, the 100 and 400 IU/day dosages did not significantly reduce vertebral fracture risk. Effects on nonvertebral fractures were not significant (RR = 0.80; 95% CI 0.59, 1.09; p = 0.16). There is mounting evidence to show that calcitonin diminishes bone pain in osteoporotic vertebral fractures, which may have clinical utility in vertebral crush fracture syndrome. A recent study suggests that nasal salmon calcitonin appears to be a promising therapeutic approach for the treatment of men with idiopathic osteoporosis, although long-term trials are necessary to confirm these results and evaluate fracture rate as an endpoint in men. The role of calcitonin in corticosteroid-induced osteoporosis remains controversial, hence it can only be considered a second-line agent for the treatment of patients with low bone mineral density who are receiving long-term corticosteroid therapy.

Abstract
The most devastating consequence of osteoporosis is bone fracture, particularly at the vertebral or femoral level. As defined by the WHO, patients with osteoporosis who have had one or more fragility fractures have severe osteoporosis. Those who sustain a vertebral fracture represent a particularly vulnerable group whose risk of another vertebral fracture within the following year is increased by a factor of 3-5. In addition, the presence of a vertebral fracture is associated with an increased risk of hip fracture. In light of these data, treatment of established osteoporosis is extremely important to prevent other fragility fractures. This review examines the therapies approved by the US FDA for the treatment of osteoporosis that have been shown to reduce the incidence of new fractures in patients with established osteoporosis. We evaluated the mechanisms of action, available formulations, efficacy in preventing fractures and increasing bone mineral density (BMD), duration of treatment, adverse effects and contraindications to use of alendronic acid (alendronate), risedronic acid (risedronate), calcitonin, raloxifene and teriparatide. All these drugs are able to prevent new vertebral fractures in patients with established osteoporosis. Only alendronic acid and risedronic acid have also been shown to reduce the risk of fracture at the femoral level, but they are contraindicated in patients with upper gastrointestinal diseases. Calcitonin is a good option in subjects with back pain because of its analgesic effect. Raloxifene is useful when patients have high plasma lipid levels or a family history of breast cancer. Teriparatide is indicated in subjects with very low BMD and multiple vertebral fractures. Patient characteristics should determine selection of therapy but the decision is always difficult and fraught with uncertainty.

Abstract
Calcitonin (CT) was first reported as a hypocalcemic principle, initially thought to originate from the parathyroid gland, a view subsequently corrected to an origin from parafollicular C-cells. Human CT is a 32 amino acid peptide with an N-terminal disulphide bridge and a C-terminal prolineamide residue, shown to potently inhibit bone resorption. More recent studies have demonstrated that this may take place through a direct osteoclastic action. A number of osteoclast CT receptors have subsequently been characterized and particular receptor regions necessary for ligand binding and intracellular signaling identified. Its potent anti-resorptive effect has led to its use in treating Paget's bone disease, osteoporosis, hypercalcaemia and osteogenesis imperfecta. This review summarises some key aspects of its synthesis, structure and its actions at the cellular and molecular levels, and leads on to its therapeutic uses that have emerged since its discovery as well as possibilities for future clinical applications.

Abstract
Both general and specific health status instruments can be utilised in evaluating health-related quality of life (HR-QOL) deficits resulting from osteoporotic fractures. Osteoporotic hip, vertebral and wrist fractures significantly decrease HR-QOL in most HR-QOL domains investigated. The presence of multiple vertebral fractures leads to larger decrements in HR-QOL. More research needs to be completed with these HR-QOL tools to better assess the true burden of osteoporotic fractures, particularly in the case of hip fractures, as the burden is surely being underestimated without recognition of HR-QOL. Only when the burden of fragility fractures is understood, inclusive of HR-QOL, will the value of proven antifracture prevention and treatment therapies be appreciated. Information collected by HR-QOL instruments may provide new insight as to how to improve quality of life for patients with fractures and how to properly allocate healthcare spending.

Abstract
OBJECTIVE To evaluate the analgesic efficacy of calcitonin for treating the pain of vertebral fractures associated with osteoporosis. DATA SOURCES Searches of MEDLINE (1966-July 2002), Cochrane Library, International Pharmaceutical Abstracts (1977-July 2002), and an extensive manual review of journals were performed using the key search terms calcitonin, analgesic, osteoporosis, vertebral fracture, and pain. STUDY SELECTION AND DATA EXTRACTION All articles identified from the data sources were evaluated and all information deemed relevant was included for this review. DATA SYNTHESIS Fractures, especially vertebral fractures, are a common complication of osteoporosis, leading to significant pain. Calcitonin has been studied for its analgesic properties. Fourteen double-blind, placebo-controlled trials that evaluated the analgesic efficacy of calcitonin for osteoporosis-related vertebral fracture pain were identified and reviewed. Thirteen of these studies demonstrated statistically significant improvement in pain or function in calcitonin-treated patients. CONCLUSIONS Calcitonin has proven efficacy in acute pain associated with osteoporosis-related vertebral fractures. Analgesic effects are seen with intranasal, parenteral, and rectal administration. Future studies comparing calcitonin with other commonly used analgesics are needed to more clearly define its place in therapy.

Abstract
We reviewed the epidemiology, diagnosis, and treatment of vertebral fractures due to osteoporosis in the elderly. Vertebral fractures are underdiagnosed despite their high prevalence in both men and women. Clinical consequences of vertebral fractures include increased risk of future vertebral and hip fracture, acute and chronic back pain, decreased quality of life, and increased mortality. Patients with vertebral fractures have functional impairment and increased mortality similar to those with hip fractures. Asymptomatic fractures identified on radiograph also affect quality of life and mortality. A vertebral fracture is a clinical marker for a subsequent fracture and should trigger assessment and diagnosis of osteoporosis. The care of patients with vertebral fractures includes pain management, rehabilitation, and prevention of further fractures. There is evidence from randomized controlled trials that pharmacologic therapy can reduce the risk of future fractures by 40% to 50%. Vertebroplasty may be effective in the control of pain and in obtaining stability of the spine.

Abstract
The analgesic activity of salmon calcitonin (subcutaneous or intranasal) has been demonstrated in several prospective clinical trials, in patients suffering different painful skeletal conditions, including recent nontraumatic osteoporotic vertebral fractures. The mechanism of the analgesic effect of calcitonin is not clear. It is possible that specific binding sites for salmon calcitonin exist in the brain. Another explanation is that changes in descending serotonergic modification on the sensory transmission mediated by C afferents contribute to the analgesic effects of calcitonin on pain in osteoporotic patients. From the clinical point of use, the analgesic effect of calcitonin is beneficial throughout the whole period of medical treatment of osteoporotic patients. Salmon calcitonin in a daily dose of 100 IU subcutaneously or 200 IU intranasally reduces dramatically the back pain (p < 0.0005) after a recent osteoporotic vertebral fracture, and promotes the early mobility of patients. The finding that injectable or intranasally administered salmon calcitonin effectively controls severe pain in osteoporotic patients with a recent vertebral fracture, allowing them earlier mobility in combination with a reduction of the urinary hydroxyproline excretion, and a limitation of the considerable bone loss that may occur during prolonged bed rest, make this therapeutic scheme attractive.

Abstract
Calcitonin was discovered as a hypocalcemic principal that was initially thought to originate from the parathyroid gland. This view was corrected subsequently, and an origin from the thyroid C cells was documented. The purification and sequencing of various calcitonins soon followed. Calcitonin is a 32-amino-acid-long peptide with an N-terminal disulfide bridge and a C-terminal prolineamide residue. The peptide was shown to potently inhibit bone resorption; however, a direct osteoclastic action of the peptide was confirmed only in the early 1980s. Several osteoclast calcitonin receptors have subsequently been cloned and sequenced. Specific regions of the receptor necessary for ligand binding and intracellular signaling through cyclic AMP and calcium have been identified through systematic deletion mutagenesis and chimeric receptor studies. Calcitonin's potent antiresorptive effect has led to its use in treating Paget's disease of bone, osteoporosis, and hypercalcemia. This review retraces key aspects of the synthesis and structure of calcitonin, its cellular and molecular actions, and its therapeutic uses as they have emerged over the 40 years since its discovery. The review also examines the implications of these findings for future clinical applications as a tribute to early workers to whom credit must be given for creation of an important and expanding field. Notable are the new approaches currently being used to enhance calcitonin action, including novel allosteric activators of the calcitonin receptor, modulation of the release of endogenous calcitonin by calcimimetic agents, as well as the development of oral calcitonins.

The aim of non-pharmacological intervention for osteoporosis is to prevent, treat or alleviate the consequences of osteoporosis, the main one of which is fracture. Non-pharmacological interventions consist of a wide spectrum of treatment modalities to decrease pain, correct postural change, improve mobility, enable the patient to follow a normal social life and prevent (further) fracture. An exercise programme can increase bone mass in adolescents and adults, but in the elderly its main emphasis should be on improving muscle strength and balance in order to decrease the risk of falls. Physiotherapy is commonly prescribed to mobilize the patient after a fracture, to decrease muscle spasm and pain, and to improve balance and co-ordination. An orthesis or back support may be used to correct kyphosis and decrease pain. Medication for pain is often needed and should cover both acute severe pain following fracture and chronic pain caused by postural change. A hip fracture is the most severe consequence of osteoporosis. The risk of hip fracture can be decreased by pharmacological treatment to increase bone mass and bone strength. However, in the very elderly the occurrence of falling may be more important than the failure of bone strength. Hip protectors have recently become available and have been shown to decrease the risk of hip fracture after a fall. These shunt the energy from the trochanter away to the sides. Non-pharmacological approaches to treatment are often neglected in daily practice, the emphasis being instead on treatment with drugs that decrease bone resorption and thereby increase bone strength.
