First claim
Opening claim text (preview).
The invention claimed is: 1. An orthopaedic surgical instrument comprising: a customized patient-specific surgical instrument comprising: a metallic guide body extending from a posterior end to a free anterior end, the guide body including an elongated opening that is defined in its free anterior end, a cutting guide slot extending from the opening in the guide body, the guide slot being sized and shaped to guide a cutting saw blade into engagement with a patient's bone, a first plate section extending from the posterior end of the metallic guide body, the first plate section including a pair of posterior-extending arms, each arm including a first portion of a customized patient-specific negative contour configured to receive a first portion of a corresponding positive contour of the patient's bone, and a second plate section spaced apart from the first plate section and extending from the posterior end of the metallic guide body, the second plate section including a bone-facing surface including a second portion of the customized patient-specific negative contour configured to receive a second portion of the corresponding positive contour of the patient's bone. 2. The orthopaedic surgical instrument of claim 1 , wherein the customized patient-specific surgical instrument further comprises: a first boss attached to, and extending from, the second plate section to an end spaced apart from the free anterior end of the guide body, the first boss including an opening that is defined in its end, and a first drill guide slot extending from the opening in the first boss, the first drill guide slot being sized and shaped to guide a surgical drill into engagement with the patient's bone. 3. The orthopaedic surgical instrument of claim 2 , wherein the customized patient-specific surgical instrument further comprises: a second boss attached to, and extending from, a first arm of the pair of posterior-extending arms to a free end, the second boss including an opening that is defined in its free end, and a second drill guide slot extending from the opening in the second boss, the second drill guide slot being sized and shaped to guide a surgical drill into engagement with the patient's bone. 4. The orthopaedic surgical instrument of claim 3 , wherein the customized patient-specific surgical instrument further comprises: a third boss attached to, and extending from, a second arm of the pair of posterior-extending arms to a free end, the third boss including an opening that is defined in its free end, and a third drill guide slot extending from the opening in the third boss, the third drill guide slot being sized and shaped to guide a surgical drill into engagement with the patient's bone. 5. The orthopaedic surgical instrument of claim 1 , wherein the customized patient-specific surgical instrument is a single monolithic metallic component including a plurality of laminations.
