Distal femoral cutting block instrument

A medical device to facilitate a distal femoral cut of a femur of a patient,

• the medical device comprising:
• a base portion comprising a surface extending along a first plane between a distal end and a proximal end;
• one or more projecting portions having at least one surface extending in a second plane perpendicular from the first plane, the one or more projecting portions protruding from the base portion along or near the distal end of the base portion;
• and a cutting guide coupled to the base portion, the cutting guide configured to guide cutting of the distal femoral cut;
• wherein the base portion, the one or more projecting portions, and the cutting guide are configured to engage femoral condyles of the femur when the medical device is placed on a knee joint of the patient, wherein the cutting guide comprises a textured surface facing the base portion, the textured surface configured to engage along anterior facing surfaces of the femoral condyles when the medical device is placed on the knee.

A medical device to facilitate a distal femoral cut of a femur of a patient,

• the medical device comprising:
• a base comprising a planar surface between a distal end and a proximal end;
• and a cutting guide configured to guide cutting of the distal femoral cut;
• and wherein the base and the cutting guide are configured to engage femoral condyles of the femur when the medical device is placed on a knee joint to facilitate cutting of the distal femoral cut without requiring insertion of an intermedullary femoral rod into the femoral canal of the knee, wherein the cutting guide has a textured surface for engaging anterior facing surfaces of the femoral condyles when the medical device is placed on the knee joint.

A medical device to facilitate a distal femoral cut of a femur of a patient, the medical device comprising:

• a base comprising a planar surface extending along a first plane between a distal end and a proximal end of the base, wherein the planar surface of the base is configured to engage with distal facing surfaces of femoral condyles when the medical device is placed on a knee joint;
• one or more projections extending from the distal end of the base, wherein the one or more projections have one or more planar surfaces that are configured to engage along posterior facing surfaces of the femoral condyles when the medical device is placed on the knee joint;
• a cutting guide configured to guide cutting of the distal femoral cut, wherein the cutting guide comprises a stepped surface facing the base, the stepped surface configured to engage along anterior facing surfaces of the femoral condyles when the medical device is placed on the knee;
• and
• a mounting mechanism that is configured to releasably couple the cutting guide along the proximal end of the base.
