Although there was no complete congruency between the plates and the radial cortex, all distal palmar radius plates investigated in this study presented a reasonable anatomical shape. The Synthes VA-LCP distal two-column-radius plate palmar showed the best anatomical fit. A low profile and optimized anatomical precontouring minimizes irritation of the surrounding soft tissues and should be considered with plate design and implant choice.
The following indications are well accepted for subtotal femur replacement: 1. Malignoma of the hip region. 2. Pertrochanteric fractures. 3. Loosening of hip prosthesis in case of large bony defects. The common devices are implanted by use of bone cement,--we report on three cases, treated by cementless subtotal femoral replacements with bony ingrowth surface. The surface design imitates the structure of spongious bone. The mean observation time of our three patients is more than two years, no complaints are to be observed. By intensive permeation of bone in the surface structure we achieve a more advantageous biomechanical situation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
