A surgical instrument, for example a cutting block for use in knee surgery, comprises a mounting surface defining at least one opening for receiving a mounting projection. The mounting surface further defines a blind recess which extends linearly from the at least one opening. The blind recess may extend to an edge of the mounting surface. A system including a surgical instrument and one or more mounting projections is also disclosed. The blind recess can be used as a track to guide a projection to an opening, increasing the area of the instrument that can be used to locate the projection in the correct position. The recess acts as a guide for the projection to enter the opening by providing tactile feedback to guide the projection towards the opening. If the recess also extends to the edge of the instrument, the recess may be visible more easily when the surgeon is installing the instrument providing visual as well as tactile feedback.

1. A surgical instrument system for use with a bone, comprising: a mounting projection adapted for insertion into the bone; anda cutting block comprising a mounting surface, wherein the mounting surface has at least one opening for receiving the mounting projection and a recess that communicates with the at least one opening and extends linearly from the at least one opening;wherein:the cutting block has a first surface adjacent to the mounting surface, a second surface adjacent to the mounting surface and spaced from the first surface, a surface opposite the mounting surface, a width between the first surface and the second surface and a depth between the mounting surface and the opposite surface;the cutting block also has an elongate cutting guide slot extending through the entire depth of the cutting block for guiding resection of the bone;the cutting guide slot extends in a direction different from the direction of the recess in the mounting surface;the recess is a blind recess that extends from the at least one opening to one of the first and second surfaces and is sized so as to act as a track to guide the mounting projection to the at least one opening;the recess has an end between the first and second surfaces; andthe at least one opening is positioned at the end of the recess. 2. The surgical instrument system of claim 1, wherein the recess does not extend through the entire depth of the cutting block. 3. The surgical instrument system of claim 1, wherein the cutting block is placed on the mounting projection after the mounting projection has been inserted into the bone. 4. The surgical instrument system of claim 2, wherein the recess extends to a first edge of the mounting surface such that the recess extends into the first surface, and wherein the recess is generally straight and substantially perpendicular to the first edge of the mounting surface. 5. The surgical instrument system of claim 4, wherein the recess has a width that increases in the direction towards the first surface. 6. The surgical instrument system of claim 4, wherein the recess has a depth that increases in the direction towards the first surface. 7. The surgical instrument system of claim 6, wherein the recess flares outwardly at a junction with the first surface. 8. The surgical instrument system of claim 1, wherein the mounting surface defines a plane and has a first opening and a second opening, each opening sized to accept a mounting projection; wherein a first recess extends from the first opening and a second recess extends from the second opening; wherein both the first and second recesses extend to a first edge of the mounting surface such that both the first and second recesses extend into the first surface; and wherein the first and second recesses are substantially parallel to each other in the plane of the mounting surface. 9. The surgical instrument system of claim 1, wherein the mounting surface has at least one further opening sized to receive a mounting projection and wherein no recess extends from the at least one further opening. 10. The surgical instrument system of claim 1, wherein the cutting block has a plurality of elongate cutting guide slots extending through the entire depth of the cutting block. 11. A surgical cutting block, comprising: a mounting surface that has a first opening and a second opening, each sized to receive a mounting projection;a first surface adjacent to the mounting surface and a second surface adjacent to the mounting surface, the cutting block having a width extending between the first and second surfaces and a depth extending from the mounting surface;a plurality of elongate cutting guide slots extending through the entire depth of the cutting block from the mounting surface;wherein the mounting surface has a first recess that does not extend the entire depth or the entire width of the cutting block, the first recess extending linearly from an end at the first opening and a second recess that does not extend the entire depth or the entire width of the cutting block, the second recess extending linearly from an end at the second opening, the first and second recesses being substantially parallel to each other in the plane of the mounting surface; and wherein both the first recess and the second recess extend to opposite ends at a first edge of the mounting surface such that both the first recess and the second recess extend into the first surface adjacent to the mounting surface. 12. The surgical cutting block of claim 11, wherein at least one of the first recess and the second recess has a width that increases in the direction towards the first surface. 13. The surgical cutting block of claim 11, wherein at least one of the first recess and the second recess has a depth that increases in the direction towards the first surface. 14. The surgical cutting block of claim 11, wherein at least one of the first recess and the second recess is generally straight and substantially perpendicular to the first edge of the mounting surface. 15. The surgical cutting block of claim 11, wherein the mounting surface has at least one further opening sized to receive a mounting projection and wherein no recess extends from the at least one further opening. 16. A surgical cutting block, comprising: a mounting surface that has at least one opening for receiving a mounting projection, a first surface adjacent to the mounting surface, a second surface adjacent to the mounting surface, a width extending between the first and second surfaces, a depth extending from the mounting surface, a plurality of elongate cutting guide slots extending through the entire depth of the cutting block from the mounting surface, and a recess that does not extend through the entire width or depth of the cutting block, the recess extending linearly from an end at the at least one opening to a first edge of the mounting surface such that the recess extends into the first surface; andwherein the recess has a width that increases in the direction towards the first surface. 17. The surgical cutting block of claim 16, wherein the recess has a depth that increases in the direction towards the first surface. 18. The surgical cutting block of claim 16, wherein the recess is generally straight and substantially perpendicular to the first edge of the mounting surface. 19. The surgical cutting block of claim 17, wherein the mounting surface has at least one further opening sized to receive a mounting projection and wherein no recess extends from the at least one further opening. 20. The surgical cutting block of claim 17, wherein each cutting guide slot extends in a different direction than the recess.
