[Mechanical performance of non slotted small diameter nails of Gross and Kempf].

The goal of this study was to evaluate the mechanical properties of closed section small diameter Grosse-Kempf tibia nails. This type of implant has been advocated for an unreamed nailing of open tibia fractures in order to avoid further damage of bone blood supply and an increased risk for compartment syndrome. Static and dynamic tests were performed on 9 and 10 mm nonslotted Grosse-Kempf (G-K) and Russel-Taylor (R-T) nails.

In vivo determination of long bone flexibility--the epiphyses influence.

A lot of studies are devoted to the in vivo vibration analysis of long bones. In general they compare mechanical parameters relative to two instrumented bones or to one bone considered in different configurations. In this study a method of E.
