Methods All patients younger than 70 years of age undergoing isolated aortic valve replacement from October 2005 to October 2011 were analyzed. Patient-prosthesis mismatch was defined as the indexed effective orifice area ≤ 0,85cm2/m2. We studied the impact of patient-prosthesis mismatch on mid-term overall mortality, cardiac events and New York Heart Association functional class using an analy...

Total wrist arthroplasty are not used as widely as total knee and hip replacement. The functional hands are requiring surgeons to design a durable and functional satisfying prosthesis. This article will list the main reasons that cause the failure of the prosthesis. Some remarkable and representative prostheses are listed to show the devolvement of total wrist prosthesis and their individual sp...

The Birmingham Mid Head Resection (BMHR) arthroplasty can be used as an alternative to conventional stemmed total hip arthroplasty in young patients unsuitable for hip resurfacing. This study investigated the effect of stem size on femoral neck fracture in the BMHR. Sawbones composite femurs were randomly allocated to one of the following groups: 1) Unprepared femur with no prosthesis; 2) Femur...

A 53-year-old woman who had undergone aortic valve replacement with a Starr-Edwards (S-E) valve (Model 1260) and open mitral commissurotomy 28 years previously was hospitalized with cardiac failure. Echocardiography showed mitral stenosis, mitral regurgitation, and a normally functioning S-E prosthesis. At reoperation, the mitral and aortic valves were replaced with St Jude bileaflet mechanical...

Aim: This study aimed to evaluate biological and prosthetic complications of cantilevered non-cantilevered fixed hybrid metal acrylic prostheses used for vertical inclined implants in atrophied mandible. Materials Methods: Eight completely edentulous individuals will be classified into 2 groups randomly: 1) Group I (cantilevered prosthesis, n=4): patients received 4 parallel each other’s the in...

Aesthetic anterior tooth restoration is one of the greatest challenges for dentists in clinical practice. Patients expect contemporary dentistry to provide restorations that reproduce natural beauty while ensuring stability and functionality. The Fixed dental prosthesis fabrication requires equal consideration to be given to the retainer, pontic and connector design. The excessive flexing of th...

OBJECTIVE To assess the success rate of tracheoesophageal voice prosthesis as the primary mode of voice rehabilitation in patients after total laryngectomy. METHODS Medical record files of 35 patients subjected to total laryngectomy were reviewed for determining success or failure of the voice prosthesis. The indicators used were quality of speech and utility of the device. Subsequent complic...

We report the use of the reverse shoulder prosthesis in the revision of a failed shoulder hemiarthroplasty in 19 shoulders in 18 patients (7 men, 11 women) with severe pain and loss of function. The primary procedure had been undertaken for glenohumeral arthritis associated with severe rotator cuff deficiency. Statistically significant improvements were seen in pain and functional outcome. Afte...

One of the most important factors that causes the failure of a knee prosthesis is the infection that can arise in the tissues after implantation due to an incorrect surgical procedure, to a difficult repairing process or to other patient’s pathological conditions. The infection can arise soon after implantation as well as in one or two years after the operation. In order to let the infection he...
