Infection of total hip prostheses by Peptococcus
In two cases of infected total hip replacements, Peptococcus magnus was isolated in pure culture from the implant when it was removed. Fluorescent antibody and ELISA studies have shown that both patients developed an antibody response to this anaerobic coccus soon after the replacement operation. These results suggest that the organism is a true infective agent, which was probably responsible f...
متن کاملCementless Hydroxyapatite Coated Hip Prostheses
More than twenty years ago, hydroxyapatite (HA), calcium phosphate ceramics, was introduced as a coating for cementless hip prostheses. The choice of this ceramic is due to its composition being similar to organic apatite bone crystals. This ceramic is biocompatible, bioactive, and osteoconductive. These qualities facilitate the primary stability and osseointegration of implants. Our surgical e...
متن کاملCorrosion of modular hip prostheses.
Nine uncemented hip prostheses of modular design were revised because of late infection (2 cases), femoral stem loosening or fracture (2), loosening of threaded cups (3) and protrusion of bipolar cups (2). At surgery we found tissue discoloration and macroscopic corrosion in four of the nine prostheses, located at the head-neck junction. Histological examination in most cases showed extensive n...

متن کاملPatient specific implants for amputation prostheses: design, manufacture and analysis.
OBJECTIVES To design, manufacture and analyze custom implants with functional gradation in macrostructure for attachment of amputation prostheses. METHODS The external shape of the implant was designed by extracting geometrical data of canine cadavers from computed tomography (CT) scans to suit the bone cavity. Three generations of implant designs were developed and were optimized with the he...
