Patent number: 9370386Abstract: A bone fixation plate comprises a plate body extending from a first end configured for placement over a shaft of a bone to a second end configured and dimensioned for placement over an epiphysis of the bone, an outer diameter of the plate body increasing from the first end to the second end to substantially conform to dimensions of the bone. An opening extends through the plate from a first surface which faces away from the bone when mounted thereonto to a second surface which faces the bone when in the desired orientation, the opening being positioned so that, when mounted over the bone, a fracture of the bone is visible therethrough to aid in alignment of the bone plate. First and second holes extend through the plate, each of the first and second holes being structured to lockingly engage a threaded head of a bone fixation device inserted thereinto.Type: GrantFiled: November 23, 2010Date of Patent: June 21, 2016Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Andre Galm, Martin Langer, Dirk Kerstan, Christof Dutoit, Franco Cicoira, Mirko Rocci
