1. A cutting block for resecting bone comprising:
- a body having a first generally planar bone contacting surface and a second surface spaced from said bone contacting surface along an axis perpendicular to said generally planar bone contacting surface;
said body having a perimeter surface extending between said first and second surfaces, said perimeter surface at least partially curved with respect to said axis in both a direction generally perpendicular thereto and generally parallel thereto.

Abstract
A cutting block for resecting a bone, particularly the distal femur, has a body with a first generally planar bone contacting surface to contact the resected distal surface of the femur. The body has a second surface spaced from the bone contacting surface along an axis perpendicular to said generally planar bone contacting surface. The body has a perimeter surface extending between the first and second surfaces, wherein the perimeter surface is at least partially curved with respect to the axis in both a direction generally perpendicular thereto and generally parallel thereto. The perimeter surface may be polished.

15. A cutting block for resecting a distal femur comprising:
a body having a width in a medial-lateral direction and height in an anterior-posterior direction and a proximally facing bone contacting surface and a distally facing surface opposite said proximal surface, said proximal and distal surfaces spaced along a central axis, said body having a medial and lateral perimeters extending between said proximal and distal surfaces wherein at least part of each of said perimeters is at a greater distance from said central axis than said medial and lateral perimeter at said proximal and distal surfaces and wherein the body has a width less than or equal to the medial-lateral dimension of the femur throughout the height of the block and a height less than or equal to the anterior-posterior dimension of the femur throughout the width of the block. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
