Active clinical trials for "Osteonecrosis"

Non-interventional prospective multicentre cohort study to determine a predictive score for the occurrence of osteochimionecrosis of the jaws after invasive oral surgery in patients who have received biphosphonates or antangiogenic drugs as part of chemotherapy with malignant bone disease (multiple myeloma or bone metastasis of a solid tumour). Data are collected during the usual follow-up of patients during the first 3 months following surgery.

The purpose of this pilot study is to investigate the efficacy and safety of autologous transplantation, under arthroscopy, of Bone Marrow Mesenchymal stem cells, using, with a cell separator, a fresh non-culture expanded Autologous Bone Marrow derived Mesenchymal Stem, mixed and activated with proteins scaffold in patient with Knee cartilage defects and osteoarthritis. Based on extensive preclinical investigations, the technology of using freshly isolated bone marrow mononuclear cells mixed with proteins seems safe and most effective for a one-step correction of cartilage defect and restoration of the osteochondral complex, because the same mixture can generate cartilage in the vasculature-free knee joint, and bone in the environment of bone defects.

This study was mainly aimed to evaluate the efficacy of local administration of enriched bone marrow mononuclear cells, platelets and zoledronic acid for the clinical prevention of collapse of the early-stage osteonecrotic femoral head.

To Compare Between Radiological Guided Treatment And Arthroscopic Guided Treatment Of KIENBOCK Disease

The purpose of this study is to evaluate the safety and efficacy of autologous bone marrow stem cells in sickle cell disease patients with osteonecrosis

The purpose of this study is to compare the efficacy of autologous enriched bone marrow cell implantation combined with core decompression to single core decompression for the treatment of avascular necrosis of femoral head.

Long-term follow-up of IDE patients for publication

The purpose of this study is to determine if surgical angiogenesis performed in talar avascular necrosis by free microvascular bone grafts from the medial femoral condyle is a superior technique compared to core decompression and nonvascularized osseous autografts.

The pathogenesis of AVN includes a defective blood supply to the knee joint. Local nitrates induce peripheral vasodilation and may improve blood supply to the affected tissue. This study aims to test whether the use of a nicotine patch may accelerate the healing process from AVN of the knee.

The purpose of this study is to determine if surgical angiogenesis performed in talar avascular necrosis by free microvascular bone grafts from the femoral condyle is a superior technique compared to core decompression and nonvascularized osseous autografts.
