A method for assessing the orthopaedic performance of a joint of a patient can comprise implanting at least a first and second RF wirelessly detectable markers in first and second bones associated with a site and determining and storing their positions before a surgical procedure is performed. The procedure can be carried out on the site and the positions of the first and second markers can be detected and stored after the procedure has been completed. The detected positions can be used to generate a representation of the orthopaedic performance of the joint after the procedure.

Orthopaedic monitoring system, methods and apparatus

A method for assessing the orthopedic performance of a joint of a patient can comprise implanting at least a first and second RF wirelessly detectable markers in first and second bones associated with a site and determining and storing their positions before a surgical procedure is performed. The procedure can be carried out on the site and the positions of the first and second markers can be detected and stored after the procedure has been completed. The detected positions can be used to generate a representation of the orthopedic performance of the joint after the procedure.

Orthpaedic monitoring system, methods and apparatus

A system and computer implemented method for use in determining the deviation of an intra-operative position of an orthopaedic implant from a planned position is described. The position of the orthopedic implant in the bone is defined by a plurality of implant position parameters. The distance of a plurality of anatomical features in a three dimensional model of the surface of the bone relative to a model of the implant at a first position is calculated. The first position corresponds to a first set of values for the implant position parameters. The distance of the plurality of anatomical features to a model of the implant at a second position in the bone is calculated. The second position corresponds to a second set of values for the implant position parameters, and the second position is different to the first position.

Intra-operative surgical plan changing

A method for producing a customized 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 customized 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.

Customised surgical apparatus

A customized patient-specific orthopaedic surgical system including a first surgical block, a second surgical block, and a computer-controlled milling machine. The first surgical block includes a first bone-facing surface having a first customized patient-specific negative contour to receive a first corresponding contour of a bone of a patient and a first mounting surface. The second surgical block includes a second bone-facing surface having a second customized patient-specific negative contour to receive a second corresponding contour of the bone of the patient and a second mounting surface to be separately mated with the first mounting surface. The computer-controlled milling machine includes a third mounting surface to be separately mated with the first mounting surface of the first surgical block.

Customized patient-specific computer controlled cutting system and method

A surgical instrument which can be attached to a patient is described. The instrument includes an alignment guide having a distal end and a proximal end. A brace is attached toward the proximal end of the alignment guide for attaching the instrument to a limb of a patient. The brace comprises a pair of opposed members, each member being shaped to hold a respective bony part of the patient on either side of the patient. At least a part of the brace is made of a resilient material allowing the brace to grip the patient in use.

Surgical instrument attachment

A number of orthopaedic surgical instruments are also disclosed. A method, apparatus, and system for fabricating such instruments are also disclosed.

Customized patient-specific instrumentation for use in orthopaedic surgical procedures

An implantable marker, instruments for implanting the marker and method for implanting the marker are described. The implantable marker comprises a housing with an outer surface providing a bone anchor and having a cavity within which a marker detectable by a tracking system is secured. The kit includes a guide instrument having a guide channel for receiving an implantable marker, an insertion tool receivable within the channel and having a distal end for releasably engaging an implantable marker, and an implantable marker receivable within the channel. The insertion tool is operable to drive the implantable marker into the bone. The method includes puncturing the skin with an instrument, driving the implantable marker into the bone and withdrawing the instrument, leaving the marker implanted within the bone.
