Filter by:A prospective study to determine how low bone mineral density and/or vertebral compression fractures associate with pain in adults with sickle cell disease
Medication-related osteonecrosis of the jaw (MRONJ) is a drug adverse reaction and there is no consensus for the treatment of MRONJ. The aim of this study is to evaluate the mucosal coverage using HAM after sequestrectomy in patients with stage-2 MRONJ.
This is a randomized unblinded Phase II clinical trial evaluating the impact of intensive antihypertensive control (targeted to the 50-75th percentile for age, sex, and height) compared to conventional antihypertensive control (targeted to the 90-95th percentile for age, sex, and height) on the incidence of radiographically extensive osteonecrosis in children and young adults receiving treatment for newly diagnosed acute lymphoblastic leukemia/lymphoma (ALL). Primary Objective - Compare the frequency of radiographically extensive osteonecrosis in patients receiving intensive compared to conventional antihypertensive therapy. Secondary Objectives - Evaluate the efficacy of intensive antihypertensive control compared to conventional antihypertensive control in the prevention of clinically significant (CTCAE Grade 2 or higher) and radiologically extensive osteonecrosis, overall and stratified by joints. - Compare the frequency of clinically significant and radiographically extensive osteonecrosis in patients receiving antihypertensive therapy and historical controls. - Compare blood pressures achieved in intensive and conventional arms using both pressures obtained as part of routine patient care and ambulatory blood pressure monitoring. - Compare levels of vascular dysfunction as measured physiologically, radiographically, and in blood samples in patients receiving intensive compared to standard antihypertensive therapy. Exploratory Objectives - Identify predictive patterns of blood biomarkers which identify patients at high- risk of developing clinically significant osteonecrosis. - Identify MRI findings during late induction which correlate with osteonecrosis lesions seen during reinduction. - Identify patterns of diurnal blood pressure variation as measured by ambulatory blood pressure monitoring associated with the later development of osteonecrosis. - Compare induction blood pressure control and intervention arm to echocardiographic changes at reinduction II. - Evaluate patient-reported, health-related quality of life in patients during induction and after 1.5 years of therapy when many experience the symptoms of osteonecrosis.
The objectives of this study are to obtain clinical performance (outcomes) data and survivorship for commercially available Vivacit-E (HXPE) liners. This will be done by analysis of polyethylene wear, validated outcome measurement tools, radiographs, and reported adverse events data.
Approximately 500 patients will be included in this patient registry. Data collection includes demographics, clinical data of underlying disease and use of bisphosphonates, denosumab and antiangiogenic drugs , degree and extension of osteonecrosis, osteonecrosis-specific treatment, outcomes and complications within 1 year after treatment.
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.
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 objective of this study is to collect outcome information on patients requiring Total Knee Replacement (TKR) in primary or revision cases and therefore receiving the LINK® Endo-Model® SL® under routine conditions.
ACI-C versus AMIC: A controlled randomized trial comparing Autologous Chondrocyte Implantation ( ACI) and Autologous Matrix Induced Chondrogenesis (AMIC) for repair of cartilage defects in the knee. Eighty patients (Forty in each group) having symptomatic cartilage defects in their knee are planned to include in this study. Both techniques will use the ChondroGide membrane from Geistlich to cover the defects. ACI includes an arthroscopy to harvest cartilage for cell cultivation in our lab located in Tromso. 3-4 weeks later using a mini arthrotomy the cells will be implanted under the ChondroGide membrane. The AMIC group will be listed for a mini arthrotomy, cleaning of the defect, microfracture and cover of the defect using the same ChondroGide membrane. In both groups stitches and fibrin glue will be used to fix the membrane. Inclusion criteria: Age between 18-60, Informed consent signed by patient, Symptomatic cartilage defect. Size more than 2 square cm. Exclusion criteria Alcohol or drug abuse during the last three years, Inflammatory joint disease, Serious illness Preoperative examination and follow up: Clinical examination and registration of KOOS (a validated knee score), VAS (visual analog pain scale) and Lysholm knee score. Radiographs of the involved knee including weightbearing standing radiographs of both knees. Kellgren- Lawrence classification will be used for grading of OA. Patients will be checked after 1, 2, 5 and 10 years following surgery. Symptomatic patients having a new cartilage resurfacing operation or prosthesis will be listed as failures of the initial treatment. Hypothesis: AMIC will be equal to ACI, and if that is the case this would be a benefit for the patients and the society. AMIC is much cheaper compared to ACI (needing an expensive cell cultivation and two surgeries). Data will be analyzed using the SPSS statistical package.
Mesenchymal Stem Cells (MSCs) have been shown to have immunosuppressive and repairing properties. Bone marrow mononuclear cells (BMMNCs) have revascularization properties and complimentary effects to MSCs. The investigators will infuse expanded autologous MSCs and BMMNCs into patients with osteonecrosis of the femoral head. The study purpose is to examine whether this treatment will result in improvement in osteonecrosis of the femoral head.
