Abstract: Apparatus for promoting bone growth, especially for osteosynthesis of bone fragments and/or fixation of bone fractures is described. This apparatus comprises at least one piezoelectric element, which is associated with an implant or like bone fixation means and which, under the action of forces, generates electrical pulses which serve as a stimulant for bone growth. The at least one piezoelectric element is an integral component of the implant.

Abstract: Apparatus for the osteosynthesis of bone fragments, in particular for the fixation of bone fractures comprises a retaining strap that wraps around the fracture or the bone in the region of the site to be treated. The retaining strap is in the form of a flat strip typically in the nature of a hose- or pipe-clamp. At one end of the retaining strap, which is intended to be that end which contacts the bone, there is provided a receiving element through which the other end of the retaining strap can be passed and fixed in position to hold the strap in place under tension when wrapped around the bone. The receiving element is mounted so that it can be rotated about an axis substantially perpendicular to the flat surface of the retaining strap.

Abstract: The invention is directed to a stabilizing element for the osteosynthesis of bone fragments, especially for the fixation of bone fractures, said element at least partly covering the fracture and/or the bone in the area of the treated side and adapted to be fixed to the bone by at least one tension means.
