Importance of Whole-Body Scintigraphy or Positron Emission Tomography for Early Detection of Femoral Lesions in Breast Cancer Patients Treated with Bisphosphonates.

BackgroundWe hypothesized that most of the atypical femoral fractures (AFFs) associated with bisphosphonate treatment for breast cancer (BC) could be found before the fracture event in another radiological examination already performed by breast surgeons, rather than on simple radiographs (SRs).MethodsWe thoroughly inspected the clinical charts of BC patients treated at our institute between 2008 and 2017. In total, 228 patients were categorized into three groups based on SRs: complete AFF on at least one side (group 1); incomplete fracture on at least one side, but not any complete fracture (

Rare clinical experiences for surgical treatment of melanoma with osseous metastases in Taiwan.

BackgroundMalignant melanoma occurs infrequently in Taiwan. Once it has progressed into osseous metastases, the prognosis is poor. There are no reported clinical experiences of surgical management in this area.MethodsTo improve our understanding of the rare clinical experiences, we retrospectively investigated clinical characteristics, radiological findings, treatment modalities, survival outcomes and prognoses of 11 Taiwanese patients with osseous metastasis of melanoma treated surgically at two national medical centers, National Taiwan University Hospital and National Cheng Kung University H

Case report of a tibial fracture in a patient suffering from gout: An atypical site, the importance of differential diagnosis.

We present the case of a 60-year-old man with a history of severe tophaceous gout with polyarticular involvement who came to the emergency room due to direct trauma to the right forearm and knee. The knee X-ray and CT scan showed a lateral tibial plateau fracture characterized by the presence of a lytic bone lesion. The presence of a solid neoplasm was ruled out and a CT-guided biopsy was performed. Histological evaluation revealed findings typical for an advanced intraosseous gout. As there was no significant risk of progression of the lytic lesion, the fracture site was treated conservativel

A scoping review on the surgical management of metastatic bone disease of the extremities.

BACKGROUND: Management of metastatic bone disease of the extremities (MBD-E) is challenging, and surgical directions pose significant implications for overall patient morbidity and mortality. Recent literature reviews on the surgical management of MBD-E present a paucity of high-level evidence and global inconsistencies in study design. In order to steer productive research, a scoping review was performed to map and assess critical knowledge gaps. METHODS: The Arksey and O'Malley framework for scoping studies was followed. A comprehensive literature search identified a large body of literatur

Pathophysiology and treatment of osteoporosis: challenges for clinical practice in older people.

Osteoporosis, a common chronic metabolic bone disease is associated with considerable morbidity and mortality. As the prevalence of osteoporosis increases with age, a paralleled elevation in the rate of incident fragility fractures will be observed. This narrative review explores the origins of bone and considers physiological mechanisms involved in bone homeostasis relevant to management and treatment. Secondary causes of osteoporosis, as well as osteosarcopenia are discussed followed by an overview of the commonly used pharmacological treatments for osteoporosis in older people.

Development and definition of a simplified scoring system in patients with multiple myeloma undergoing stem cells transplantation on standard computed tomography: myeloma spine and bone damage score (MSBDS).

BackgroundIn clinical practice, there is the need to optimize imaging usage in MM patients. Accordingly, the aim of this paper was to develop a simple computed tomography (CT) scoring method for MM, able to shorten and simplify the interpretation time with good intra- and inter-reader reliability. This method, named MSBDS (Myeloma Spine and Bone Damage Score) was developed with the final aim to use standard total-body CT in the routine practice of MM centres as a complement of standard evaluations in patients undergoing stem cells transplantation.MethodsWe used a widely accepted consensus form

Current Overview of Treatment for Metastatic Bone Disease.

The number of patients with bone metastasis increases as medical management and surgery improve the overall survival of patients with cancer. Bone metastasis can cause skeletal complications, including bone pain, pathological fractures, spinal cord or nerve root compression, and hypercalcemia. Before initiation of treatment for bone metastasis, it is important to exclude primary bone malignancy, which would require a completely different therapeutic approach. It is essential to select surgical methods considering the patient's prognosis, quality of life, postoperative function, and risk of pos

Changes of bone turnover markers and bone mineral density among postmenopausal Thai women with osteoporosis receiving generic risedronate.

BackgroundOsteoporosis has been recognized as a significant health issue in Thailand. Pharmacological interventions are important way to prevent fracture. However, one of the main challenges in selecting a medication is high cost, particularly for brand-name drugs. Data on generic bisphosphonate use in Thai are still lacking. Therefore, our study aimed to assess the efficacy and safety of generic risedronate in postmenopausal Thai women with osteoporosis.MethodsThis prospective study was conducted at King Chulalongkorn Memorial Hospital, Bangkok, Thailand, from December 2022 to January 2024.

Effects of dose reduction on bone strength prediction using finite element analysis.

This study aimed to evaluate the effect of dose reduction, by means of tube exposure reduction, on bone strength prediction from finite-element (FE) analysis. Fresh thoracic mid-vertebrae specimens (n = 11) were imaged, using multi-detector computed tomography (MDCT), at different intensities of X-ray tube exposures (80, 150, 220 and 500 mAs). Bone mineral density (BMD) was estimated from the mid-slice of each specimen from MDCT images. Differences in image quality and geometry of each specimen were measured. FE analysis was performed on all specimens to predict fracture load. Paired t-tests w

Chemotherapy May Obviate Prophylactic Femoral Nail Surgery for Multiple Myeloma Patients With High Mirels' Score Lesions and Impending Pathological Hip Fracture.

Bone involvement presents in >80% of patients with multiple myeloma. This causes lytic lesions for which prophylactic surgery is indicated to prevent pathological fractures if the lesion is graded ≥9/12 on Mirels' score. Although successful, these surgeries have risks and extended recovery periods. We present a case indicating myeloma chemotherapy may obviate prophylactic femoral nailing for high Mirels' score lesions in the femoral head with impending pathological hip fracture. A 72-year-old woman presented in December 2017 with back pain. A plain X-ray indicated degenerative anterolisthesis

Outcomes of Percutaneous Stabilization for Pelvic Metastatic Bone Disease: A Systematic Review and Meta-Analysis.

BACKGROUND/OBJECTIVES: Metastatic bone disease (MBD) of the pelvis is commonly managed with open reconstruction despite substantial morbidity and high complication rates ranging from 16-32%. Percutaneous fixation techniques have emerged as a lower morbidity alternative; however, robust evaluations of outcomes remain limited. Therefore, the primary aim of this systematic review was to evaluate changes in pain and function following percutaneous fixation for pelvic MBD, and to determine the complication and reoperation rates of these procedures. METHODS: A systematic review and meta-analysis wa

Proximal Femur Megaprostheses in Orthopedic Oncology: Evaluation of a Standardized Post-operative Rehabilitation Protocol.

BackgroundReconstructions of the proximal femur after massive resections represent one of the main challenges in orthopedic oncology. Among the possible treatments, megaprostheses represent one of the most used and reliable reconstructive approaches. Although literature about their outcomes has flourished through the last decades, a consensus rehabilitative treatment is still far from being established.Materials and methodsWe evaluated the functional results of all our oncologic cases treated between 2016 and 2022 that could follow our standardized post-operative rehabilitative approach, consi

Osteoporosis: Current Concepts.

Osteoporosis is a worldwide disease characterized by reduction of bone mass and alteration of bone architecture resulting in increased bone fragility and increased fracture risk. Causes of osteoporosis include increasing age, female sex, postmenopausal status, hypogonadism or premature ovarian failure, low body mass index, ethnic background, rheumatoid arthritis, low bone mineral density (BMD), vitamin D deficiency, low calcium intake, hyperkyphosis, current smoking, alcohol abuse, immobilization, and long-term use of certain medications. The diagnosis of osteoporosis is established by measure

Hypophosphatemic Osteomalacia Associated with Adefovir-induced Fanconi Syndrome Initially Diagnosed as Diabetic Kidney Disease and Vitamin D Deficiency.

A 68-year-old man with type 2 diabetes mellitus and chronic hepatitis B infection was referred to the nephrology department before planned surgery for hepatocellular carcinoma. He had been receiving low-dose adefovir dipivoxil (ADV) for 11 years. Laboratory findings revealed impaired re-absorption in the proximal renal tubules. He had been diagnosed with diabetic kidney disease and osteomalacia due to vitamin D deficiency; thus, ADV was not discontinued until he was referred to us. In this case, concomitant diabetes mellitus and vitamin D deficiency might have prevented the early diagnosis of
