a patient-specific alignment guide including a three-dimensional engagement surface customized in a pre-operating planning stage by computer imaging to closely mate and conform to a corresponding bone portion of a patient's elbow joint, the patient-specific-alignment guide defining a guiding bore for guiding a pin along a reference axis, wherein the reference axis is an anatomic axis of rotation of the elbow joint, the patient-specific alignment guide defining a guiding surface for guiding a blade for a bone-cut along a patient-specific resection plane, wherein the guiding bore and guiding surface are customized for the patient during a preoperative planning stage.
2. The medical device of claim 1, wherein the guiding surface is an exterior planar surface of patient-specific alignment guide.
3. The medical device of claim 1, wherein the guiding surface is a planar surface defined by an elongated through slot defined in the patient specific alignment guide.
4. The medical device of claim 1, wherein the guiding surface comprises three slots defined in the patient-specific alignment guide corresponding to three resection cuts of a distal humerus.
5. The medical device of claim 4, wherein the three slots defined in the patient-specific alignment guide correspond to distal, anterior, and posterior humeral cuts.
6. The medical device of claim 1, wherein the guiding surface comprises at least one slot defined in the patient-specific alignment guide, the slot configured for a corresponding resection cut of a distal humerus.
7. The medical device of claim 1, wherein the engagement surface is customized and configured for a corresponding lateral surface of a distal humerus.
8. The medical device of claim 7, wherein the three-dimensional engagement surface is shaped to conform to a lateral capitellum surface of the distal humerus of the elbow joint.
9. The medical device of claim 1, wherein the guiding bore is configured to be aligned with a medial/lateral anatomic axis of the elbow joint.
10. The medical device of claim 1, wherein the three-dimensional engagement surface is made to closely conform as a mirror image or negative to the corresponding bone portion of the patient's elbow joint.
11. The medical device of claim 1, wherein the guiding bore is formed by a tubular guiding feature defining the guiding bore.
12. A medical device for an elbow joint, comprising:
a patient-specific alignment guide including a three-dimensional engagement surface customized in a pre-operating planning stage by computer imaging to be a negative of a corresponding bone portion of a patient's elbow joint, the patient-specific alignment guide having a tubular guiding feature defining a guiding bore for guiding a pin along an anatomic axis, the patient-specific alignment guide defining a plurality of guiding slots configured for guiding a blade for a plurality of bone cuts, wherein the guiding bore and the guiding slots are customized for the patient during a pre-operative planning stage.
13. The medical device of claim 12, wherein the plurality of guiding slots includes three slots defined in the patient-specific alignment guide corresponding to distal, anterior, and posterior humeral cuts.
14. The medical device of claim 13, wherein the anatomic axis is an axis of rotation of the elbow joint.
15. The medical device of claim 14, wherein the engagement surface is customized and configured for a corresponding lateral surface of a distal humerus.
16. The medical device of claim 15, wherein the three-dimensional engagement surface is shaped to conform to a lateral capitellum surface of the distal humerus of the elbow joint.
17. A method to resect a distal humerus of an elbow joint, comprising:
positioning a patient-specific alignment guide having a three-dimensional engagement surface against a lateral surface of a distal humerus such that the engagement surface closely mates and conforms to the lateral surface of the distal humerus;
passing a pin through a guide bore defined by the patient-specific alignment guide, wherein passing the pin through the guide bore further includes passing the pin through the guide bore aligned along an anatomic axis of rotation of the elbow joint; and
guiding a blade through a patient-specific guide slot defined by the patient-specific alignment guide to cut a portion of the distal humerus.
18. The method of claim 17, wherein guiding a blade further includes guiding a blade along a first guide slot to form a distal humeral cut, a second guide slot to form an anterior humeral cut, and a third guide slot to form a posterior humeral cut.
