20080287781 | Registration Methods and Apparatus - A method, system and computer program for generating a registered image of a body part of a patient for use in an image guided surgical procedure is described. The method includes attaching a marker detectable by a tracking system to the body part before carrying out surgical steps. The tracking system has a reference frame and the position of the marker in the reference frame is detected. A first image of the body part is captured using an imaging system. An indication of the position of the first image relative to the reference frame of the tracking system is obtained. The first image is then mapped into registration with the position of the body part. The system includes an imaging system for capturing images of the body part. A tracking system detects a marker and determines the position of the marker in the reference frame of the tracking system. A marker is attachable to the body part and detectable by the tracking system. A computer control system is configured to obtain an indication of the position of the first image relative to the reference frame of the tracking system and to map the first image into registration with the position of the body part. | 11-20-2008 |
20090089034 | Surgical Planning - A method, apparatus and computer program code for automatically planning at least a part of a surgical procedure to be carried out on a body part of a patient are described. A virtual model of the body part is provided, in which the model has data associated with it representing at least a part of a planned surgical procedure. The virtual model is then morphed to the body part using data derived from the patient's real body part thereby also adapting the part of the planned surgical procedure to reflect the anatomy of the patient's real body part. | 04-02-2009 |
20110092858 | SURGICAL APPARATUS AND PROCEDURE - A computer assisted surgery method and apparatus for determining a change in a property of a joint of a patient caused by an arthroplasty procedure is described. The relative position of a first bone and a second bone of the joint is determined with the joint in a first position. The position of a pre-operative center of motion of the joint relative to the first bone is determined. The position of the second bone relative to the pre-operative center of motion is determined using the relative position of the first and second bones. The position of a post-operative center of motion resulting from a prosthetic component to be used in the joint is determined. The position of the second bone relative to the post-operative center of motion is determined. Any change in the property of the joint. is determined from the difference between the position of the second bone relative to the pre-operative center of motion and the position of the second bone relative to the post-operative center of motion. | 04-21-2011 |
20110093108 | CUSTOMISED SURGICAL APPARATUS - A method for producing a customised surgical instrument or prosthesis for a specific patient is described. At least one x-ray image of a body part of the patient is captured. A statistical model having a dense set of anatomical correspondence points across the model is instantiated using image data derived from the at least one x-ray image to generate a patient specific model of the body part having a high accuracy surface. Patient specific data from the patient specific model is used to generate a design of the customised surgical instrument or prosthesis for use in a surgical procedure to be carried out on the body part. The surgical instrument or prosthesis is then manufactured using the design. A computer implemented method for generating the patient specific model of the body part is also described. | 04-21-2011 |

20110092979 | ACETABULAR ALIGNMENT GUIDE - An alignment guide for guiding the positioning of an acetabular cup implant includes a body having a first end and a second end. A flange extends from the first end and is adapted to rest on a labrum of an acetabulum. At least a first formation is provided at the second end which is adapted to engage with a transverse acetabular ligament of the acetabulum. A formation for accepting a trackable instrument is provided to allow a tracking system to determine the orientation of the guide. | 04-21-2011 |

20080255584 | Acetabular Cup Positioning - A computer aided surgery system, method, surgical method and instrument for guiding the positioning of an acetabular cup in a pelvis are described. The position of the transverse acetabular ligament of the pelvis and the position of the acetabular labrum of the pelvis are determined. The orientation of an acetabular plane including the acetabular labrum and the transverse acetabular ligament is calculated. A planned position for the acetabular cup is determined, in which an inlet plane of the cup is substantially parallel to the acetabular plane. The instrument comprises a mounting for attaching the instrument to a patient, a support, a guide defining a longitudinal axis, and for receiving a further instrument bearing the acetabular cup implant, and an adjustment mechanism. The adjustment mechanism can allow the angular orientation of the guide to be adjusted about at least two different axes to allow the inclination and version or anteversion of the longitudinal axis to be altered. | 10-16-2008 |
20100030231 | SURGICAL SYSTEM AND METHOD - Methods, systems and data processing apparatus and methods are described for use in planning and carrying out a surgical procedure on a joint of a subject. The joint includes a first component and a second component, the first and second components being relatively movable. Joint data describing the configuration of the joint is captured while the joint is in a functional state wherein the joint is undergoing its usual load bearing functional behaviour. The joint data is analyzed to determine joint component orientation data specifying the relative orientation of the first and second components. The orientation of prosthetic implants to be used in the surgical procedure to recreate the joint is planned using the joint component orientation data. The planned orientation of the prosthetic implants improves the recreation of the functional state of the joint. | 02-04-2010 |
