Modern hand prostheses are capable of mimicking finger or wrist movements using electrical motors, gear mechanisms and control elements. The drive systems and the transmission mechanisms emit machinery noises which can activate or enforce a foreign body sensation by users. Transfer-path-analysis is originally developed to investigate the individual vehicle noise paths. It is a useful tool for t...

Study objective—To determine the relative costs of prostheses and factors associated with changes in these cost rankings. Design and setting—Economic model using published data. Main results—The main cost drivers are current costs and revision rates. Expected revision costs are a small proportion of the expected total costs. There are few competitors to the “gold standard” Charnley in terms of ...

OBJECTIVE: The purpose of this study was to determine the fracture strength of zirconium implant abutments and the torque required to unfasten the retaining screw before and after applying cyclic loading to the implant-abutment assembly. The dynamic behavior and stress distribution pattern of zirconium abutments were also evaluated. METHODS AND MATERIALS: Static and cyclic loading of 7 XiVE imp...

Relationship of Life Satisfaction and with Fixed Implant-Supported Prostheses in the Elderly

A low profile prosthesis was designed using a flexible liner in conjunction with a rigid shell, with a toe extension. Thus far, two paediatric patients have been fitted with the device, at the University of Virginia Medical Center. One patient is a five year old with a Lisfranc level amputation and the other, a sixteen year old with a Chopart level amputation. Both patients have successfully wo...

One of the major obstacles in developing reliable walking neural prostheses is poor performance of the sensors which are used for gait phases identification. Improper functioning of these sensors causes wrong stimulation pattern selection and wrong stimulation sequencing of the walking neural prostheses. These malfunctions often cause unstable walking patterns in patients that are using the pro...

A prospective, randomised and independently assessed trial of the Ring UPM total hip replacement showed that the quality of the early result was better if the femoral prosthesis was cemented than if it was not. More patients with cemented prostheses were painfree at four months (58% cemented:42% uncemented) and at one year (63% cemented:50% uncemented), but at two years pain relief was equal in...
