Publication number: 20110071574Abstract: The invention relates to an osteosynthesis implant (1) that preferably consists of a bioresorbable plastic material. The inventive implant receives the longitudinal fixation elements (10) to be anchored in the bone, especially in the form of wires, nails, pins or screws. The openings destined to receive the fixation elements (10) do not completely extend through the implant (1) like in conventional bone plates or intramedullary nails but are degenerated to indents (2) in the surface of the implant (1) so that they may serve as a guide for the fixation elements (10) to be guided through the implant (1). The inventive implant (1) allows insertion of the fixation elements (10) in the bone diverging angles and crossing one another, so that the fixation elements (10) extending intramedullarly or in the spongiosa are primarily prevented from migrating in a proximal or distal direction.Type: ApplicationFiled: November 23, 2010Publication date: March 24, 2011Applicant: Synthes USA, LLCInventors: Markus Hehli, Reto Frei, Georg Duda
