Patent number: 9603670Abstract: A method for designing and/or optimizing an implant that has one or more through holes with a central axis for receiving a bone fixation element. The method includes: providing a general collection of three-dimensional bone quality data obtained from a patient population; identifying in the patient population N>2 categories of patients with significantly different N>2 homologous sub-collections of bone quality data; and designing an implant or optimizing an existing implant for each of the N>2 sub-collections such that the at least one through hole is located at an optimal place and with an optimal direction of the central axis relative to the implant. The optimal position and direction is chosen based on each of the N>2 sub-collections of data so as to obtain an optimal anchorage of the bone fixation element in the bone when introduced through the through hole.Type: GrantFiled: February 25, 2010Date of Patent: March 28, 2017Assignee: AO Technology AGInventors: Stefano Brianza, Damiano Schiuma, Andrea Tami

Patent number: 9326779Abstract: A drill guide for guiding elements, especially drill bits and implants of an implantation kit during a surgical intervention, has a main body having a gripping portion. The drill guide has an upper and a lower central opening along its longitudinal axis with a through going cavity for receiving the element to be guided. A lower contact surface is positioned on an object, such as a bone, on or into which the element is to be guided. The diameter of the through going cavity can be varied by a.) radial positioning of three or four jaws inside the cavity through a groove-slide block system and/or b.) against the force of a spring at the lower free end of guiding extensions. The spring is provided on the back side of the extensions which bear against the inner wall of the drill guide sleeve.Type: GrantFiled: January 4, 2013Date of Patent: May 3, 2016Assignee: Stryker European Holdings I, LLCInventors: Klaus Dorawa, Stefano Brianza
