OBJECTIVE To describe the surgical procedure for placement of an implantable telescope prosthesis for end-stage age-related macular degeneration. METHODS As part of a phase 2/3 clinical trial for patients with bilateral, irreversible age-related macular degeneration, the optimal procedure for monocular placement of the telescope prosthesis was determined. RESULTS Because of the unique confi...

In the surgery of aortic valve replacement is always attempted, as much as possible, to implant the larger prosthesis with the mains goals to enhance the potential benefits, to minimise transvalvular gradient, decrease left ventricular size and avoid the phenomenon of patient-prosthesis mismatch. Implantation of an ideal prosthesis often it is not possible, due to a small aortic annulus. A vari...

BACKGROUND Conventional stemmed anatomical shoulder prostheses are widely used in the treatment of glenohumeral osteoarthritis. The stemless shoulder prosthesis, in contrast, is a new concept, and fewer outcome studies are available. Therefore, the purpose of the study was to investigate the early functional outcome and postoperative proprioception of a stemless prosthesis in comparison with a ...

In order to determine the magnitude of temperature increases in resurfaced hips, temperature sensors were placed percutaneously in both hip joints of 12 volunteer patients who had 1 or both joints resurfaced. Temperature recordings were made with patients at rest (baseline) and after patients walked for 20 and 60 minutes. The hip resurfacing procedures were performed 12 to 36 months prior to th...

OBJECTIVES To identify whether measurement of the prosthesis length is mandatory in patients requiring otosclerosis surgeries and to assess their postoperative audiometric outcomes. In addition, evaluation of prosthesis length used in revision compared to primary stapedectomy was carried out. STUDY DESIGN Case series with chart review. METHODS Chart review of 393 patients undergoing primary...

To minimize the weight of the prosthesis various techniques that create a hollow prosthesis have been known. There are a lot of drawbacks of these techniques as they are complex, time consuming, and of high cost. Here is a technique that utilizes putty material for fabricating hollow denture prosthesis.

An interim obturator prosthesis is required for the restoration of speech, deglutition, and improvement of esthetics after maxillectomy. This article describes a simple method for fabricating the interim obturator prosthesis by duplicating the patient's teeth and palate. The interim obturator prosthesis fabricated by duplication of the presurgical appearance and contour may be more acceptable t...

We quantify how the hip energetics and knee torque required for an above-knee prosthesis user to walk with the kinematics of able-bodied humans vary with the inertial properties of the prosthesis. We also select and optimize passive mechanical components for a prosthetic knee to accurately reproduce the required knee torque. Previous theoretical studies have typically investigated the effects o...

Comparisons were made between the Intelligent Prosthesis (IP), Mauch and pneumatic swing phase control damping systems on the same prosthesis worn by a high level trans-femoral amputee. Speeds self selected by corridor walking (4.4-5.5 kmh-1) proved not to be sustainable for treadmill walking. Comfortable speeds were attained when the subject walked on a treadmill at 2.0, 2.6 and 3.2 kmh-1 in t...

A Syme amputation, which is the most conservative below-the-knee amputation and which provides the best functioning stump for weight-bearing, has been rarely recommended for women, because the unsightly prosthesis is objectionable. Some time ago it was necessary to amputate the foot of a female patient, twenty-two years old. After a conference with the young woman, it was decided that the many ...
