Abstract
A patient-specific alignment guide includes 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 defines a first longitudinal guiding bore aligned with a reference axis associated with the elbow joint of patient when the alignment guide is mounted onto the corresponding bone portion.

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. - View Dependent Claims (18)
