Patent number: 9113976Abstract: A bone screw is provided having first and second threaded portions of different diameter separated by a middle portion that is unthreaded so that the bone screw may be inserted into a pair of adjacent bone fragments and used to compress the fragments together by driving the screw into a hole drilled in the fragments. An installation tool is also disclosed for threadably engaging one end of the bone screw and is used to initially drive the screw into the bone hole. Thereafter, a screwdriver may be inserted through the tool and into engagement with a recess in the bone screw and may be used to drive the screw fully into the bone and to separate the bone screw from the installation tool. A method of installation is further provided.Type: GrantFiled: August 12, 2013Date of Patent: August 25, 2015Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Yan Yevmenenko, Walter Pistoia, Andre Frenk, Florian Beutter, Franco Cicoira

Patent number: 8460349Abstract: A device for manipulating bone fragments includes a bone screw includes a shaft extending along a longitudinal axis. The shaft includes a first end having a first threaded portion with a first core diameter, a first external diameter and a first pitch. The shaft includes a second end having a second threaded portion with a second core diameter, a second external diameter and a second pitch. The second end further has a tool engaging surface, wherein the first external diameter is no greater than the second core diameter, the first and second pitches are substantially equal, and a non-threaded middle segment between the first and second threaded portions, an outer diameter of the middle segment being smaller than the first core diameter, and wherein the shaft includes a cannulation extending therethrough disposed coaxial with the screw longitudinal axis.Type: GrantFiled: August 22, 2012Date of Patent: June 11, 2013Assignee: Synthes USA, LLCInventors: Andre Frenk, Florian Beutter, Franco Cicoira
