Patent number: 10022130Abstract: An orthopedic surgical instrument including a polymer 4-in-1 femoral cutting block having a chamfer cutting slot defined therein, and a chamfer cutting guide assembly secured within the chamfer cutting slot. The chamfer cutting guide assembly includes a first planar surface, a second planar surface spaced apart from, and extending parallel to, the first planar surface, a third planar surface connected to the second planar surface and extending at an angle relative to the first planar surface and a fourth planar surface connected to the first planar surface and extending parallel to the third planar surface. The first planar surface and the second planar surface define a first metallic planar cutting guide, and the third planar surface and the fourth planar surface define a second metallic planar cutting guide. The chamfer cutting guide assembly may include a pair of metallic bushings.Type: GrantFiled: November 27, 2013Date of Patent: July 17, 2018Assignee: DePuy Ireland Unlimited CompanyInventors: Jon M.
