摘要： A method of automatically registering a surgical navigation system to a patient's anatomy is provided. The method comprises programming a surgical navigation system with a first spatial relationship between a surgical component and a reference array connected to the surgical component, programming the surgical navigation system with a second spatial relationship between an anatomical feature of a patient and the surgical component, installing the surgical component on the patient such that the surgical component engages the anatomical feature in the second spatial relationship, and locating the reference array with the surgical navigation system. The navigation system automatically recognizes the position of the reference array relative to the patient's anatomy.

摘要： A bone preparation system including a guide body and a plurality of bone locators. The guide body is configured to mate with a patient-specific module having a patient-specific module surface customized based on image data of a specific patient to correspond to the patient's specific bone geometry. The plurality of bone locators are coupled to the guide body and positioned by the patient-specific module surface to define a patient-specific bone engaging surface of the guide corresponding to the patient's specific bone geometry.

摘要： A method for pre-operative orthopedic planning includes obtaining only a high-resolution knee-joint scan of a patient, determining hip rotation center and ankle rotation center from anthropometric data based on personal data of the patient, and determining a mechanical axis of the knee joint based on the anthropometric data. The method also includes preparing at least a two-dimensional image model of the knee joint using the knee-joint scan and the determined mechanical axis, and preparing a pre-operative surgical plan based on the image of the knee joint.

摘要： A method of preparing a knee joint for a prosthesis in a patient includes mating a patient-specific three-dimensional curved inner surface of a femoral alignment guide onto a corresponding three-dimensional femoral joint surface of the patient. The patient-specific three-dimensional curved inner surface is preoperatively configured from medical scans of the knee joint of the patient. First and second holes are drilled into an anterior portion of the femoral joint surface through corresponding first and second guiding apertures of the femoral alignment guide.

摘要： A bone preparation guide including a first patient-specific portion based on image data of a specific patient's bone and configured to match the patient's specific bone surface. A second patient-specific portion is based on image data of the specific patient's bone and configured to match the patient's specific bone surface. A patient-generic portion is configured to be a bone-facing portion supported by the first and the second patient-specific bone contacting members at a portion of the patient's bone surface not imaged during preparation of a preoperative plan.

摘要： A patient-specific alignment guide includes a patient-specific portion and a guiding element having a through opening. The patient-specific portion has a patient-specific surface preoperatively configured to mate as a negative of a portion of an iliac crest of a pelvis of a specific patient and mate to the iliac crest only in one position. The guiding element has a preoperatively configured orientation and location relative to the patient-specific portion for preparing a bore in the bone of the patient to direct a bone screw at the preoperatively configured orientation and location for sacroiliac fixation.

摘要： A patient-specific guiding system for guiding an instrument relative to a portion of an anatomical feature of a patient. The patient-specific guiding system includes a patient-specific guide. The guide includes a first portion having a first patient-specific inner surface that conforms to a first surface of the anatomical feature and an outer surface opposite the first patient-specific inner surface. The first portion also includes a guide surface for use in guiding the instrument relative to the anatomical feature. The guide also includes a second portion having a second patient-specific inner surface that conforms to a second surface of the anatomical feature and an outer surface opposite the second patient-specific inner surface. The second portion is removably connected to the first portion.
