Impacts of Prior Anti-Osteoporosis Treatments on Sequential Denosumab Responses in BMD Changes Among Postmenopausal Osteoporosis Women in East China: Real-World Data Analysis.

PURPOSE: This study aimed to investigate the impacts of prior anti-osteoporosis treatments on bone mineral density (BMD) changes in Chinese postmenopausal women with osteoporosis following 1-year Denosumab (Dmab) therapy. PATIENTS AND METHODS: This retrospective cohort study enrolled 381 postmenopausal women, all receiving a 1-year Dmab treatment. Participants were stratified into five groups based on prior anti-osteoporosis treatments: no treatment (NT), alendronate (ALN), zoledronic acid (ZOL), teriparatide (TPT), and raloxifene (RAL). Potential factors influencing BMD changes were screened

Hospital-related healthcare expenditure of impending versus completed pathological femur fractures: a propensity score matched study of 265 patients.

BACKGROUND AND PURPOSE: The prevalence of metastatic bone disease as well as the accompanying societal costs are expected to increase due to advances in cancer treatment. While the literature suggests that there is economic value in prophylactic stabilization compared with the fixation of completed pathological fractures in long bone metastases, studies are limited by their small sample sizes and insufficient correction for potential confounders. We aimed to evaluate whether prophylactic treatment of an impending femur fracture was associated with lower healthcare costs compared with completed

Bone Health for Gynaecologists.

Osteoporosis, the most common bone disorder, profoundly impacts women's health, especially during postmenopausal phases. Characterised by diminished bone mineral density (BMD), it increases the risk of fractures, affecting mobility, quality of life, and potentially mortality. The present review analyses the intricate interactions among physiological alterations, diseases, and medications that lead to bone mineral density reduction in women. It underscores the importance of gynaecologists in the prevention, diagnosis, and management of osteoporosis via early risk assessment, suitable hormone tr

Hairy cell leukemia with isolated bone lesions.

Key clinical message18F-FDG PET/CT has clinical relevance in HCL at diagnosis and for the follow-up of patients treated, especially in case of atypical presentations such as bone involvements (which are probably underestimated) and poor bone marrow infiltration.AbstractBone lesions are rarely reported in Hairy Cell Leukemia (HCL). We report two BRAFV600E mutated HCL patients presented bone lesions at foreground, poor bone marrow involvement, and the important role 18F-FDG PET/CT played in their management. We discuss the crucial role that 18F-FDG PET/CT could play in HCL routine practice.

Effect of exercise on bone-related outcomes in patients with cancer affected by bone metastases or bone loss: a systematic review and meta-analysis.

INTRODUCTION: This systematic review and meta-analysis aimed to evaluate the effects of exercise interventions on bone mineral density (BMD), bone mineral content (BMC), and bone turnover markers in patients with cancer and compromised bone health. MATERIALS AND METHODS: A comprehensive search of four electronic databases was conducted to identify randomized controlled trials evaluating the effect of exercise intervention compared to supplementation or bone-targeted agents only on BMD, BMC and bone turnover markers. Meta-analyses were performed using random-effects models to calculate effect

Osteoporosis Diagnosis and Management: A Review from an Orthopedic Perspective.

Osteoporosis is a systemic skeletal disorder characterized by low bone density and microarchitectural deterioration, both of which lead to increased risk of fracture, disability, institutionalization, and mortality. Dual-energy X-ray absorptiometry (DEXA) remains the gold standard for evaluating bone mineral density and establishing diagnostic thresholds. However, accurate interpretation requires more than the application of numerical cut-offs. Interpretation requires careful evaluation of graphical bands, artifact recognition, awareness of site discordance, and application of least significan

Diffusion MRI for Assessment of Bone Quality; A Review of Findings in Healthy Aging and Osteoporosis.

Diffusion MRI (dMRI) is a growing imaging technique with the potential to provide biomarkers of tissue variation, such as cellular density, tissue anisotropy, and microvascular perfusion. However, the role of dMRI in characterizing different aspects of bone quality, especially in aging and osteoporosis, has not yet been fully established, particularly in clinical applications. The reason lies in the complications accompanied with implementation of dMRI in assessment of human bone structure, in terms of acquisition and quantification. Bone is a composite tissue comprising different elements, ea

Treatment of bone tumours by radiofrequency thermal ablation.

Radiofrequency thermal ablation (RFTA) is considered the treatment of choice for osteoid osteomas, in which it has long been safely used. Other benign conditions (chondroblastoma, osteoblastoma, giant cell tumour, etc.) can also be treated by this technique, which is less invasive than traditional surgical procedures. RFTA ablation is also an option for the palliation of localized, painful osteolytic metastatic and myeloma lesions. The reduction in pain improves the quality of life of patients with cancer, who often have multiple morbidities and a limited life expectancy. In some cases, these

Randomized controlled trial of pre-transplant zoledronate versus observation for prevention of bone loss in allogeneic hematopoietic cell transplantation.

BackgroundApproximately half of allogeneic hematopoietic cell transplantation (HCT) recipients experience significant bone loss in the early post-HCT period. Only recently have international guidelines started recommending early screening. However, the guidance for intervention remains conservative. In this study, we sought to evaluate the efficacy of pre-transplant prophylactic zoledronate in preventing early bone loss in allogeneic HCT recipients.MethodsThis was an open-label, investigator-initiated, phase 2 randomized controlled trial (RCT) of prophylactic zoledronate versus observation to

Bridging the Gap: Pregnancy-And Lactation-Associated Osteoporosis.

Early diagnosis of pregnancy- and lactation-associated osteoporosis (PLO) is mandatory for a good outcome. Standard care is not a matter of conventional guidelines, rather it requires an individualized strategy while true overall incidence and pathogeny remain open issues. This is a narrative review based on full-length English articles, published between January 2021 and March 2023 and accessed via PubMed (no traumatic fractures or secondary osteoporosis are included). Our case-sample-based analysis included 836 females with PLO (the largest cohort based on published cases so far) through 12

Treatment of metastatic lesions localized in the acetabulum.

BackgroundMetastatic lesions localized in the periacetabular area cause troublesome pain and reduced mobility of the patients. Radiotherapy effectively decreases pain, yet it does not restore the ability to load the joint. Surgical treatment involving resection of metastatic lesions and joint reconstruction using bone grafts is burdened with a high rate of complications. Modular tumor prostheses are being increasingly used. In some cases, it is possible to strengthen the acetabular roof with bone cement using vertebroplasty kits. The aim of the study was to demonstrate various methods of treat

Adult-onset hypophosphatemic osteomalacia as a cause of widespread musculoskeletal pain: A retrospective case series of single center experience.

BACKGROUND: Osteomalacia (OM) is frequently confused with various musculoskeletal or other rheumatic diseases, especially in patients with adult-onset widespread musculoskeletal pain because of its low prevalence and non-specific manifestations. AIM: To facilitate the early diagnosis and etiology-specific treatment of adult-onset hypophosphatemic OM. METHODS: A retrospective review of medical records was performed to screen adult patients who visited a physiatry locomotive medicine clinic (spine and musculoskeletal pain clinic) primarily presenting with widespread musculoskeletal pain at a s

The IlluminOss® photodynamic bone stabilization system for pathological osteolyses and fractures of the humerus: indications, advantages and limits in a series of 12 patients at 24 months of minimum follow-up.

BACKGROUND: Locked titanium nails are considered the reference treatment for metastatic bone lesions of the humerus in patients with aggressive histotypes, high risk of fracture or when estimated survival is lower than 6 months.Nevertheless, they are responsible for CT and MRI artifacts which interfere with postoperative radiotherapy and follow-up.The IlluminOss® is an intramedullary stabilization system which is introduced inside the humeral canal in a deflated state, and is then distended with a monomer which hardens after exposure to blue light,stabilizing the segment; it does not cause art

Cancer treatment-induced bone loss.

Cancer treatment-induced bone loss (CTBL) is associated with anti-tumor treatments, including endocrine therapies, chemotherapeutic treatments, radiotherapy, glucocorticoids, and tyrosine kinase inhibitors. Osteoporosis, characterized by the loss of bone mass, can increase the risk of fractures, leading to mortality and long-term disability, even after cancer remission. Cancer and osteoporosis have marked clinical and pathogenetic similarities. Both have a multifactorial etiology, affect the geriatric population, and markedly influence quality of life. Lifestyle management, including calcium a

Utility of monthly minodronate for osteoporosis after gastrectomy: Prospective multicenter randomized controlled trials.

AimOsteoporosis in patients after gastrectomy is increasing with the aging of gastric cancer patients. Bisphosphonates are effective treatments for osteoporosis; however, their safety or efficacy in postgastrectomy patients has not been established. The purpose of this multicenter prospective intervention study was to investigate the impact of monthly minodronate on osteoporosis after gastrectomy.MethodsOf the 261 enrolled gastric cancer patients, 164 patients were diagnosed with osteoporosis based on criteria of the Japan Society of Osteoporosis. They were randomly assigned 1:1 to groups trea

Body Composition Predictors of Adverse Postoperative Events in Patients Undergoing Surgery for Long Bone Metastases.

IntroductionBody composition assessed using opportunistic CT has been recently identified as a predictor of outcome in patients with cancer. The purpose of this study was to determine whether the cross-sectional area (CSA) and the attenuation of abdominal subcutaneous adipose tissue, visceral adipose tissue (VAT), and paraspinous and abdominal muscles are the predictors of length of hospital stay, 30-day postoperative complications, and revision surgery in patients treated for long bone metastases.MethodsA retrospective database of patients who underwent surgery for long bone metastases from 1

Primary Osteoporosis Induced by Androgen and Estrogen Deficiency: The Molecular and Cellular Perspective on Pathophysiological Mechanisms and Treatments.

Primary osteoporosis is closely linked to hormone deficiency, which disrupts the balance of bone remodeling. It affects postmenopausal women but also significantly impacts older men. Estrogen can promote the production of osteoprotegerin, a decoy receptor for RANKL, thereby preventing RANKL from activating osteoclasts. Furthermore, estrogen promotes osteoblast survival and function via activation of the Wnt signaling pathway. Likewise, androgens play a critical role in bone metabolism, primarily through their conversion to estrogen in men. Estrogen deficiency accelerates bone resorption throug

Exploring versatile applications of a vacuum-assisted bone harvester in orthopedic surgery.

BACKGROUND: Orthopedic procedures often require removing bone or pathological tissue, with traditional methods involving instruments like curettes and rongeurs. However, these methods can be time-consuming and lead to increased blood loss. To mitigate these side effects, vacuum-assisted tools have been developed to aid in tissue removal. These devices enable surgeons to suction tissue without discarding it, potentially improving outcomes in conditions such as osteomyelitis or tumor removal while enabling collection of the material for downstream applications. Despite limited research, vacuum-a

Percutaneous lumbopelvic fixation for pathologic sacral fractures and spinopelvic dissociation: patient series.

BackgroundBecause patients with advanced cancer live longer, the number of patients with the sequelae of metastatic spine disease has increased. Pathologic instability of the mobile spine has been classified, and minimally invasive surgery has been well described. However, pathologic sacral instability is uncommon and often underdiagnosed. Although most sacral fractures are stable, patients with unstable U- or H-type fractures have spinopelvic dissociation and can experience progressive pain, sacral kyphosis, and neurological injury. Open lumbopelvic fusion carries a high perioperative risk fo

Osteolytic lesions: Multiple myeloma or prostate cancer?

Multiple myeloma is a cancer which is characterized by proliferation of malignant B-cells and plasma cell infiltration of bone marrow. Lytic lesions are one of its hallmarks, on radiological assessment. We report 2 cases who presented within 1 year to our hospital with bony lytic lesions on CT scan. They were investigated for multiple myeloma; however, there were no further features to suggest this. Both patients were confirmed to have prostate cancer. This is unusual as prostate cancer produces sclerotic lesions (unusual hardening or thickening of the bone).
