Periosteal distraction
First Claim
Patent Images
1. A method for expanding, stretching or displacing bone tissue comprising:
- (i) inserting subperiostealy at least part of a displacing device comprising a movable subperiosteal element and a force inducing mechanism configured after activation so as to move said movable subperiosteal element;
said movable subperiosteal element is configured after activation of said force inducing mechanism so as to induce forces displacing at least part of said periosteal tissue and to create a space between said moveable subperiosteal element and the bone;
said device is configured to allow ingrowth of bone tissue inside said space;
(ii) activating said force inducing mechanism.

Abstract
Devices and methods for gradual displacing of the periosteal tissue covering bones. The gap developing between the bone and the displaced periosteal tissue will be filled with bone callus as it is in distraction osteogenesis. The devices and methods allow formation of bone in distraction osteogenesis without cutting a segment of the bone.
