Filter by:The purpose of this prospective, randomized study was to compare the clinical and radiographic results and the prevalence of osteolysis of the cementless total hip arthroplasty with an alumina-on-alumina bearings one side and alumina-on-highly cross-linked polyethylene bearings on the other side in the young and active patients.
The purpose of this study is to analyze the safety and feasibility of direct administration intrafemoral mesenchymal stem cells (MSCs) in vitro expanded autologous treatment of patients with femoral osteonecrosis.
Osteonecrosis of the Jaw (ONJ) Case Registry
The purpose of this study is to investigate the efficacy and safety of autologous transplantation of Adipose Tissue derived Mesenchymal stem cells (MSCs) in patient with avascular necrosis of the femoral head.
The aim of this study is to evaluate the effects of an exercise program with a cycle ergometer in functional outcome and related-health quality of life (RHQL) in elderly patients with total hip arthroplasty.
The present study evaluates the effect of XCEL-MT-OSTEO-ALPHA in osteonecrosis of the femoral head in comparison to the standard treatment of isolated core decompression. XCEL-MT-OSTEO-ALPHA is a tissue engineering product composed by "ex-vivo" expanded autologous mesenchymal stem cells fixed in allogenic bone tissue. The working hypothesis proposes that the tissue engineering is a valid and useful technique to achieve bone regeneration, avoiding the progression to collapse of the femoral head.
The purpose of this study is to establish whether or not there is a clinical advantage to the use of Aquamantys® System from Medtronic Advanced Energy (formerly Salient Surgical Technologies) in patients undergoing primary total hip arthroplasty via the anterior supine intermuscular surgical approach in terms of blood loss, transfusion and wound healing. Wound healing will be assessed by a blinded observer and based upon a simple and subjective criteria: a) as expected, b) better than expected or c) worse than expected. The blinded observer is experienced in the care of the surgical patient and wound evaluation.
In stage 3 Osteonecrosis (ON) of the femoral head, a beneficial effect of bone marrow grafting was reported with a reduction of the functional evolution and the necessity of a total prosthesis placement in a non-controlled retrospective trial. Based on this experience, the investigators would like to start a randomized controlled double blind study on the effect of autologous implantation of autologous bone marrow cells into the necrotic lesion of stage 3 ON of the femoral head.
The investigators determined whether 1. new short, metaphyseal-fitting cementless anatomical femoral stem provides major functional improvements 2. radiographically secure implant fixation is achieved with this new stem 3. the bone content is preserved at the baseline level or above at the final follow-up 4. these procedures are associated with early failure and complications.
This pilot trial studies the differentiation of bone sarcomas and osteomyelitis with ferumoxytol-enhanced magnetic resonance imaging (MRI). Imaging procedures that allow doctors to more accurately differentiate between malignant bone sarcomas and osteomyelitis may help in diagnosing patients correctly and may result in more timely treatment.
