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.

摘要： An orthopedic device for a shoulder joint includes a patient-specific alignment guide. The alignment guide includes a cap having a three-dimensional engagement surface customized in a pre-operative plan by computer imaging to be complementary and closely mate and conform to a humeral head of a proximal humerus of a patient. The alignment guide includes a tubular element extending from the cap and defining a longitudinal guiding bore for guiding an alignment pin at a patient-specific position and orientation determined in the pre-operative plan, and an orientation feature on the cap. The orientation feature is designed to orient the cap relative to the humeral head when the orientation feature is aligned with a landmark of the proximal humerus.

摘要： A cut block positioning jig including a first alignment member, a second alignment member, and both first and second guide members. The first alignment member is movable towards and away from a patient's bone to which the positioning jig is mounted to arrange the jig at a predetermined position relative to the bone based on x-rays of the patient. The second alignment member is movable towards and away from the bone to arrange the jig at the predetermined position relative to the bone. The first and second guide members are configured to direct cut block support members to the bone to couple a cut block to the bone to provide the bone with patient-specific cuts.

摘要： A method of positioning a femoral cutting guide on a distal end of a femur establishes at least a first reference plane to perform a distal femoral planar cut. The method includes inserting a mounting member into an intramedullary canal of the femur and coupling a bridge member to the mounting member. The method also includes placing a cutting guide member over a medal anterior portion of the distal femur. The cutting guide member has a first channel that establishes the first reference plane. The bridge member has a bridge channel. A wall of the bridge channel is inserted into the first channel of the cutting guide member. A mounting mechanism generates resistance between the bridge member and the cutting guide member. The resistance is overcome by positioning the cutting guide member relative to the femur.

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 method for preparing a backup kit for a plurality of patient-specific arthroplasty procedures scheduled at the same medical facility includes providing a database with data from completed arthroplasty procedures using patient-specific arthroplasty kits. The database includes comparisons between preoperatively planned implant size and intraoperatively implanted implant size. The method includes determining a statistically expected implant size deviation from a planned implant size for each implant included in a plurality of patient-specific arthroplasty kits prepared for a shipment to the medical facility using the database. A backup kit of backup implants is assembled for the shipment. The number and size of the backup implants is determined from the statistically expected implant size deviations.

摘要： An orthopedic implant includes a first portion including at least one feature modified to be patient-specific and match the anatomy of a specific patient from a three-dimensional digital image of a patient's joint using computer modeling. The orthopedic implant includes a non-custom inner bone-engaging surface including a plurality of planar surfaces configured for engagement with non-custom bone cuts.

摘要： A method of preparing a distal femur for a knee joint implant includes mounting a patient-specific bone engagement surface of a femoral alignment guide on a complementary surface of a distal femur of a patient. A plurality of alignment pins is inserted through a corresponding plurality of guiding bores of the femoral alignment guide into the distal femur. A cutting guide is mounted on first and second alignment pins of the plurality of alignment pins, and a first resection of the distal femur is made using the cutting guide while cutting through the femoral alignment guide.

摘要： An orthopedic device for cutting or resurfacing an outer bone surface of a bone of a patient includes first and second guides. Each guide has a patient-specific surface preoperatively configured as a negative surface of a portion of the outer bone surface of the bone and a plurality of elongated slots. The elongated slots of the second guide are offset relative to the elongated slots of the first guide and configured for guiding a tool to resurface the outer bone surface.

摘要： A surgical kit for preparing a joint surface to receive an implant includes a patient-specific guide for a joint surface. The patient-specific guide has a patient-specific surface complementary to a surface of the joint for nesting engagement, and a guiding element oriented along a patient-specific alignment axis. The alignment axis is determined during a preoperative plan of the specific patient for implant alignment. The kit includes a guiding tool couplable to the guiding element of the patient-specific guide and a three-dimensional orientation device removably couplable the guiding tool for intra-operative calibration, such that, after calibration, the orientation device can be removably coupled to a shaft of a surgical instrument to align the shaft along the alignment axis.
