BACKGROUND After an upper limb amputation a prosthesis is often used to restore the functionality. However, the frequency of prostheses use is generally low. Movement kinematics of prostheses use might suggest origins of this low use. The aim of this study was to reveal movement patterns of prostheses during basic goal-directed actions in upper limb prosthetic users and to compare this with exi...

Medical prostheses constitute an indispensable component of modern health care. Like other approaches of medical intervention, the insertion of medical prostheses can be associated with serious complications. The ongoing advances in the mechanical properties of medical prostheses have not necessarily resulted in lower rates of prosthesis-related infection. Infection remains the most common seri...

This study was designed to assess platelet activity in vivo with vascular prostheses seeded with endothelial cells to determine the time course for development of thromboresistance and to test the ability of prostheses to produce prostacyclin. Sixteen dogs were randomly allocated to receive seeded (experimental group) or unseeded (control group) velour Dacron aortic prostheses. Serial measureme...

Background: The CarboMedics Top-Hat aortic valve prosthesis was designed to be implanted in a supra-annular position. This study aimed compare the hemodynamic performance of prostheses versus standard prostheses.
 Methods: included 98 patients who had replacement and were divided into two groups. Group A 60 prostheses, B 38 prostheses. endpoints hospital outcomes, effective orifice area, p...

BACKGROUND Posterior-stabilized total knee prostheses were introduced to address instability secondary to loss of posterior cruciate ligament function, and they have either fixed or mobile bearings. Mobile bearings were developed to improve the function and longevity of total knee prostheses. In this study, the International Consortium of Orthopaedic Registries used a distributed health data ne...

background: above all methods effective learning results from decent training, acquired in the proper environment and encouraging creative methods. computer-assisted training by educational software is considered a fundamental measure to improve medical and dentistry education systems. this study aims to design and assess fixed dental prostheses via 2 multimedia instructional contents at the gu...

OBJECTIVE This study investigates the effect of regular airflow, as an isolated single factor, through Groningen and Provox2 voice prostheses on biofilm formation. MATERIAL AND METHODS Groningen and Provox2 voice prostheses were placed in a modified Robbins device and inoculated with the total microflora from an explanted Groningen voice prosthesis. After 3 days, prostheses were either flushe...
