Enhancement of Bone Regeneration and Healing in the Extremities by the Use of Autologous BonoFill-II

The purpose of this clinical study is to evaluate the safety and the efficacy of BonoFill-II as an autologous bone-regenerating graft in the reconstruction of deficient bone in two clinical indications: 1. Long and short bone extra-articular comminuted fracture 2. Long and short bones extra and intra articular defect /Gap or non-union, incapable of self-regeneration

Sustained Acoustic Medicine (SAM) for Symptomatic Treatment of Pain Related to Bone Fracture

The purpose of this study is to assess the ability of long-duration low-intensity therapeutic ultrasound (LITUS) to alleviate bone-fracture related pain over a 12-week period. The primary objective of this study is to evaluate the analgesic effect of LITUS in subjects suffering from bone-fracture pain. Secondary objectives are to assess the ability of LITUS to improve patients return to work time.

Effects of Photobiomodulation on Functional Recovery of Proximal Humerus Fractures

Among the various complications of the postoperative evolution of proximal humerus fractures (PHF) are pain and joint stiffness, generating significant functional limitation in the affected limb. This randomized controlled double-blind clinical study aims to evaluate the effects of photobiomodulation (PBM) on the functional recovery of participants with PHF surgically treated with special locking plates. The primary outcome, to be assessed at 1, 2, 4, 8, and 12 weeks, will be shoulder function recovery using the Quick-DASH functional scale. Secondary outcomes will include shoulder range of motion assessments with a digital goniometer, quality of life measured using the SF-6 questionnaire, and the occurrence of adverse effects during all experimental periods. Pain will be evaluated at 1, 2, 4, 8, and 12 weeks; fracture consolidation will be assessed through radiographic examinations at 4, 8, and 12 weeks; and muscular strength will be evaluated through progressive weight-bearing exercises at 8 and 12 weeks. Data will be presented as means ± SD, with significance set at a p-value of 0.05.

The Impact of Glomerular Disorders on Bone Quality and Strength

The primary objectives of this study are to: (1) determine the impact of glomerular disease on bone strength and (2) investigate the pathophysiologic underpinnings of impaired bone strength in glomerular disease.

Efficacy of Bioceramic Materials for Bone Defects Repair

The purpose of this study is to demonstrate the effect of bioceramic implants on the repair of human bone defects, and to explore the application of bioceramic materials in bone defects, bone implantation, and bone fusion. The surface microstructure of β-tricalcium phosphate bioceramic implants can be effectively controlled to guide the regeneration of bones, promote the restoration of bones, accelerate the speed of recovery, and improve bone quality, which is of great clinical and social significance.

OSTEOMICS: Identifying Regulators of Bone Homeostasis

Diseases of bone associated with ageing, including osteoporosis (OP) and osteoarthritis (OA), reduce bone mass, bone strength and joint integrity. Current non-surgical approaches are limited to pharmaceutical agents that are not disease modifying and have poor patient tolerability due to side effect profiles. Developing a fundamental understanding of cellular bone homeostasis, including how key cell types affect tissue health, and offering novel therapeutic targets for prevention of bone disease is therefore essential. This is the focus of OSTEOMICS. A number of factors have been linked to increased risk of bone disease, including genetic predisposition, diet, smoking, ageing, autoimmune disorders and endocrine disorders. In our study, we will recruit patients undergoing elective and non-elective orthopaedic surgery and obtain surgical bone waste for analysis. This will capture a cohort of patients with bone disorders like OP and OA, in addition to patients without overt clinical bone disease. We will study the relationship between the molecular biology of bone cells, bone structure, genetics (DNA) and environmental factors with the aim of identifying and validating novel therapeutic targets. We will leverage modern single cell technologies to understand the diversity of cell types found in bone. These technologies have now led to the characterisation of virtually every tissue in the body, however bone and bone-adjacent tissues are massively underrepresented due to the anatomical location and underlying technical challenges. Early protocols to demineralise bone and perform single cell profiling have now been developed. We will systematically scale up these efforts to observe how genetic variation at the population level leads to alterations in bone structure and quality. Over the next 10 years, we will generate data to comprehensively characterise bone across health and disease, use machine learning to drive analysis, and experimentally validate hypotheses - which will ultimately contribute to developing the next generation of therapeutic agents.

Metabolic and Bone Changes After Adjuvant Cancer Treatments in Early Non-metastatic Breast Cancer

Breast cancer is the most common cancer type in European women. Patients treated for early non-metastatic breast cancer comprise a growing group of survivors due to early diagnosis and improved treatment. Many of these survivors experience adverse effects such as decreased bone mineral density, derangement of metabolic markers (fat, glucose, insulin) and increased blood pressure. Increasing risk of bone fracture and cardiometabolic disease (eg. diabetes mellitus type 2). The purpose of this study is to identify mechanisms behind cardiometabolic changes that may be connected to the (neo-)adjuvant treatment. On top of this we hope to indentify potential biological markers that can help prevent development of metabolic disease. We will be recruiting 120 post-menopausal women age 50-70 with early breast cancer and 1-2 times a year for 5 years examine bone mineral density, body composition, glucose and fat metabolism and nerve damage. A questionnaire will be used to collect information on diet, physical activity and quality of life. Derudover anvendes spørgeskemaer til at indsamle information vedrørende. This new knowledge will help clinicians start adequate preventive measures to help patients avoid cardiometabolic disease secondary to cancer treatment.

HealthEast Community Hip and Knee Replacement Registry

HealthEast Care System began the first community-based joint replacement registry (HJRR) in the U.S. in 1991, and now has more than 30,000 total joints registered. The purpose of the HJRR is to maintain and improve the care of individuals undergoing joint replacement surgery by providing timely information to their surgeons and the broader orthopaedic community. As it moves into the third decade, the HJRR is proud of its role in the development of the national American Joint Replacement Registry (AJRR) and will remain an important contributor to the larger national effort in the advancement of orthopaedic science.
