The elbow is a stable, congruent joint. The hamstring graft of eight patients was biopsied at different follow-up times from 1 to 10 years. The objective o... One of the main critical aspects behind the failure or success of an implant resides in its ability to fast bond with the surrounding bone.

In particular, the complex interactions among the different stabilizers when injured at the same time have been better understood. This prospective study reports our experience with the box-loop reconstruction technique, compared with traditional Lateral Collateral Ligament (LCL) and eventual Medial Collateral Ligament (MCL) reconstruction, showing its functional outcome at 12-month follow-up. Rotator cuff tear arthropathy (RCTA) includes a wide spectrum of clinical signs and symptoms caused by the contemporary presence of three main features: rotator cuff insufficiency, degenerative changes of the glenohumeral joint, and superior migration of the humeral head.

In an attempt to limit the occurrence of such a complication, The use of scaffolds for Tissue Engineering (TE) is increasing due to their efficacy in helping the body rebuild damaged or diseased tissue. In joint arthroplasty one of the main issues related to the failure of prosthetic implants is due to the wear of the ultra-high molecular weight polyethylene (UHMWPE) component. Alessandro Gasbarrini Bone metastases are only apparently similar lesions, considering the large varieties of istotypes and the spread of the primary tumour. patient complained of the return of sciantica in the L5 region. ...

Scaffold fixation represents one of the most serious challenges in osteochondral defect surgery. Nel 2009 è dirigente medico 1° livello, UOC in ortopedia e traumatologia presso il Policlinico Casilino. To boost osseointegration, the ideal implant material should exhibit composition and structure similar to those of biological apatite. In this study we investigate the possibility to boost bone regeneration in an experimental defect in rabbit femoral condyle by combining static magnetic fields and magnetic biomaterials. Copyright 2017 Alessandro Civani | Tutti i diritti riservati | Powered by, Un campo che ha destato il mio interesse e che sta portando. The use of magnetism in tissue engineering is a very promising approach, in fact magnetic scaffolds are able not only to support tissue regeneration, but they can be activated and work like a magnet attracting functionalized magnetic nanoparticles (MNPs) injected close to the scaffold enhancing tissue regeneration. It is hard to make a classification of patellofemoral instability. Dirigente medico Osp SS. He’s member of the leading European scientific society, and has participated as speaker at numerous international conferences. Arthroscopy has already shown its usefulness in all the joints, by improving the visual field of the joint surface with a minimally invasive surgical approach. old in order to assess mortality rate in the year after surgery and risk factors associated. Total Elbow Arthroplasty in the last decades underwent an important improvement in long-term durability and complication rates, making them increasingly suitable even for challenging conditions as post-traumatic elbows. Each of these approaches presents inherent advantages in specific cases of trauma reconstruction, but no single approach can be considered optimal for the treatment of all the different patterns of distal humerus fractures. The aim of this study was to assess the results of this technique in humeral nonunion. Nonetheless successful results have been achieved for small defect repair, the... Osteochondral defects (i.e., defects which affect both the articular cartilage and underlying subchondral bone) are often associated with mechanical instability of the joint and therefore with the risk of inducing osteoarthritic degenerative changes. The use of ceramic coatings to improve mechanical, chemical, and biological properties of a large variety of materials including polymers and metals has often produced technologically attractive as well as problematic surfaces to study, because of their complicate morphology compared to smooth surfaces obtained, for example, by atomistic processes.... Hallux rigidus, Latin for Stiff Toe, is characterized by an osteoarthritic degeneration of the articular surfaces of the first metatarsophalangeal joint. Quartiere Nomentano.

NdFeB permanent magnets are implanted close to biomimetic... Calcium phosphate (CaP) coatings are commonly employed to improve the bioactivity of bone and dental metal implants, due to the chemical–physical similarity with the mineral phase of bone, envisaged to enhance the integration with the surrounding bone tissue. In both cases, results can be frustrating: physical therapy is often not sufficient to gain functional range of motion, and after surgical release it is common to lose part of the motion gained in operating room. This paper reports an in-vitro study for evaluating the influence of the femoral tunnel orientation in anterior cruciate ligament (ACL) double-bundle reconstructions. Nel 1980 consegue la Maturita’ Scientifica presso “ La Scuola d’Italia” del consolato italiano degli Stati Uniti a New York. Wear of ultra-high molecular weight polyethylene (UHMWPE) has been recognized as the main cause for long-term revision in joint arthroplasty. Radial head prosthetic replacement is indicated in case of comminuted fracture not amenable to internal fixation, especially when the radial head fracture is part of a pattern of lesions configuring a complex instability of the elbow. la presa in carico del paziente sottoposto a intervento ortopedico alessandro mosca infermiere ortopedia bassini obiettivo obiettivo fornire conoscenze in merito al paziente ortopedico e nella gestione infermieristica nell'immediato post-operatorio. Its main advantage is that markers do not need to be attached to the implants as traditional marker-based RSA requires.
