Filter by:This study is part of the clinical evaluation of SEBBIN silicone gel-filled testicular implants, included in the technical file of the device. The aim of the study is to gather additional data about the safety and effectiveness of the device.
Registry of Galeazzi Orthopedic Institute: provides for the regular and systematic collection of all data (clinical and some PROMs) obtained from patients undergoing hip and knee arthroplasty to which questionnaires are proposed investigating the specific functional sphere of the joints undergoing surgery (Knee injuryOsteoarthritisOutcomeScore (KOOS-PS) and Hip injuryOsteoarthritisOutcomeScore (HOOS-PS) but also the sphere of general health (ShortForm health survey-12 (SF-12) and VisualAnalogueScale (VAS)) , in addition, of course, to the satisfaction rate.
The implantation of artificial hip joints is one of the most frequently performed surgeries. Normally, patients are very satisfied with the results. The MobileLink hip prosthesis system is a CE marked medical device. This means the the safety and performance of the prosthesis ist approved. Aim of the study is to collect clinical data about the outcome of the MobileLink hip prosthesis system under routine condition and to determine the satisfaction of the patients.
The One tooth - One time (1T1T) innovative approach is a straightforward and cost-effective protocol to replace a missing tooth in the posterior region (Lambert and Mainjot 2017) (see Appendix). The digital impression of single unit implants right after the implant placement and the direct manufacturing of a Polymer-Infiltrated Ceramic Network (PICN) screw-retained crown allows the delivery of a final tooth in occlusion within the same day. The absence of lab procedures reduces the number of appointments, providing immediate results and high patient satisfaction. The prosthesis material choice is crucial in this procedure. Indeed, PICN high resilience, i.e. damping effect, could reduce peri-implant strain compared to ceramic materials (Magne, Silva et al. 2013) (Maminskas, Puisys et al. 2016), moreover its elastic modulus is close to tooth tissues, while other CAD-CAM composites value is too low and ceramic materials are too high. The rapid milling and manufacturing process, without any firing procedure, and the ease of adjustments (particularly to adjust proximal and occlusal contact points), make also PICNs well-adapted to chair-side systems. The material low stiffness and hardness can improve patient comfort and promote adaptation of the restorations to occlusal relationships with time. The 1T1T approach was presented as a proof of concept in a first international publication using tissue level implants from Straumann, which describes the whole protocol (Lambert and Mainjot 2017). Currently, a case series including 10 teeth is on-course, showing a 100% survival rate of implants and restorations after a 2-yr follow-up. These results are very promising but further clinical research is needed to validate such a protocol on a larger number of patients, on other implant systems as well as to compare this approach to conventional protocols.
This bi-directional, multicentre study aims to assess multiparametric MRI Radiomics-based prediction model for identifying metastasis lymph nodes and prognostic prediction in breast cancer.
Currently there is an increase in the use of bioprosthesis worldwide (> 70% according to national data of the Spanish Society of Thoracic and Cardiovascular Surgery). There is conflicting evidence regarding the long-term survival of patients aged 50-65 years with mechanical (M) or biological (B) aortic prostheses. General consensus of greater complications associated with the use of long-life anticoagulation in M and of reoperation in B. Similar survival with lower MACCE complications in bioprosthesis could reconsider their choice in patients aged 50-65 years, specially in the current TAVI era. The investigators are going to perform a multicentric retrospective observational study (Registry) about 15 year-outcomes Following Bioprosthetic vs Mechanical Isolated Aortic Valve Replacement for Aortic Stenosis in Patients Aged 50 to 65 Years in 30 Cardiovascular Surgery Centers in Spain
Several surgical options for the reconstruction of massive bone defects have been described and include biologic methods with autografts and allografts, and the use of tumor endoprostheses (total femoral replacement, TFR). Several types of modular TFR are available, but nevertheless unpredictable outcomes and high complication rates have been described from most authors. The aim of the present study was to compare complication rates after TFR performed with modular total femur prosthesis MML (Fa. ESKA/Orthodynamics) in patients with and without malignant disease.
This study evaluates the success rate, as the biological and prosthesis complications, of posterior single-unit implants immediately loaded with a chair side Computer-Aided Design and Manufacturing (CAD-CAM) composite crown, after a follow-up period of 6 months,1,2,3,4 and 5 years. Complementary ex vivo analyses will be performed to evaluate the wear of restorations. The time and cost benefit of the presented digital workflow, as patient centered outcomes will also be evaluated.
