Gas chromatography-mass spectroscopy analysis of emissions from cement when using ultrasonically driven tools.

abstract：BACKGROUND AND PURPOSE:There is considerable uncertainty about the optimal treatment of displaced 4-part fractures of the proximal humerus. Within the last decade, locking plate technology has been considered a breakthrough in the treatment of these complex injuries. METHODS:We systematically identified and reviewed c...

abstract：BACKGROUND:Aseptic loosening is the major cause of implant failure. In cemented hip arthroplasty, failure of the acetabular side is mainly due to lysis caused by wear particles. By using an implant with low wear characteristics and by enhancing acetabular fixation using an uncemented implant, we aimed to reduce acetabu...
