Filter by:Monocentric, non-interventional Post-Market Clinical Follow-Up (PMCF) Study on past implantations of the Prevision® prosthesis; the survival rate of the Prevision® prosthesis shall be evaluated and compared to literature results on comparable Revision stems.
The uncemented Symax hip stem is developed through optimization of the uncemented Omnifit hip stem. The Symax stem design combines an anatomical anteverted proximal geometry with a straight distal section. The proximal part is coated with a biomimetic hydroxyapatite (HA) coating for improved osseointegration to enhance load transfer and to minimize proximal bone loss. The distal part is treated with an anodization surface treatment in order to prevent distal bone apposition, which is expected to prevent distal loading and reduce proximal stress shielding. Aim of this study is to report mid-term clinical performance and evaluate whether the radiographic features are in line with the design principles of the Symax hip in an international clinical study with 5 years of follow-up.
A multi-centre, non-comparative, prospective post-market clinical follow-up study to obtain survival, clinical and radiographic outcomes data on the Zimmer Fitmore Hip Stem.
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 5 Cardiovascular Surgery Centers in Andalousia (south Spain)
To prospectively monitor the survival rate of Ankylos® dental implants, comparing delayed versus immediate loading, using abutments with the SynCone® concept for implant-supported detachable dental prosthesis (ISDDP) in the edentulous upper jaw.
The aim of this study is to assess the effect of the newly introduced (hybrid dental ceramic) superstructure materials, Vita Enamic versus IPS Emax on implant stability, patient satisfaction and crestal bone loss.
Subjects are being asked to participate in this study because they have an arm or leg amputation and have developed pain related to a neuroma (an ongoing localized pain related to a cut nerve ending). The investigators are studying how targeted reinnervation (TR) helps to both treat neuroma pain and to have increased prosthetic control. This surgery connects these cut nerve endings to nerves going into nearby nonfunctional muscles. This surgery was developed to allow amputees to have better prosthesis control. By chance, neuroma pain improved significantly with TR. The investigators, therefore, are conducting this clinical trial. The investigators will ask all participants to fill out a questionnaire both before and after surgery. This will help us understand how a neuroma affects the quality of life of amputee will allow us to understand how to best improve neuroma pain and prosthesis control. In order to confirm the presence and location of the neuroma before surgery, a magnetic resonance image (MRI) will be performed. Taking these pictures requires subjects to lie still for a short period of time but does not involve any invasive procedures.
This phase II clinical trial was designed to assess the feasibility, safety, toxicity, recurrence and survival pattern when TP or CAP chemotherapy was combined with adjuvant radiation for patients with high-risk endometrial cancer.
The purpose of this study is to compare three different core build-up materials for dental use. The study hypothesis is that there is no differences in survival rate of the different core build-ups.
Clinical evaluation of 4 different bearings in THA. Primary parameter being prosthetic survival data.
