We retrieved 159 femoral heads at revision surgery to determine changes in surface configuration. Macroscopic wear of the head was observed in three bipolar hip prostheses as a result of three-body wear. There was a considerable change in surface roughness in the internal articulation of bipolar hip prostheses. Roughness in alumina heads was almost the same as that in new cobalt-chromium heads....

A functional electrical stimulation system with surface electrodes and four stimulation channels was developed. The proposed system was used to design two neural prostheses for spinal cord injured subjects and stroke subjects. One prosthesis was used to restore a grasping function in high lesioned tetraplegic subjects. The other prosthesis was used to eliminate the ‘drop foot’ problem in incomp...

Defects in the maxilla associated with oroantral and oronasal communications generally affect patient’s function and esthetics leading to emotional imbalance. Reconstructive surgery is an option, but sometimes presents unsatisfactory results. Rehabilitation using obturator prostheses in edentulous patients often contributes to inadequate stability. The literature demonstres that intra-oral endo...

New cost effective scanning and modeling techniques are used today to process data acquisition and 3D reconstruction in order to fabricate prostheses and orthoses by 3D printing. Paper approaches two scanning and 3D modeling techniques used in order to fabricate orthoses and prostheses. In this study, an artificial prosthetic ear was produced through 3D printing using two scanning techniques: s...

Approximately 1 million metal-on-metal (MoM) hip prostheses have been implanted worldwide to alleviate pain, restore hip function, and improve overall quality of life. These implants contain femoral and acetabular bearing surfaces that are typically composed predominantly of cobalt (Co) and chromium (Cr). Although the majority of MoM hip replacements have been successful, multiple recent report...
