An orthopedic device includes a monolithic patient-specific guide. The patient-specific guide includes a three-dimensional contact surface preoperatively configured from medical scans of a specific patient as a negative surface of a medial portion of a proximal femoral bone of the patient according to a preoperative surgical plan for the patient. The guide also includes a proximal planar surface configured for guiding a resection of a femoral neck of the patient, and a scale formed on the planar surface. The scale is configured for indicating a preoperatively planned femoral version of a femoral stem implant and deviations therefrom.

A patient-specific unicompartmental tibial guide has a patient-specific body with an inner surface. The inner surface is preoperatively configured to nestingly conform and mate in only one position with an anterior portion and a proximal portion of a tibial bone of a specific patient. The tibial guide includes a vertical resection channel having a variable width preoperatively configured for guiding a vertical resection through the proximal portion of the tibial bone.

Robotic systems and methods for robotic arthroplasty. The robotic system includes a machining station and a guidance station. The guidance station tracks movement of various objects in the operating room, such as a surgical tool, a humerus of a patient, and a scapula of the patient. The guidance station tracks these objects for purposes of controlling movement of the surgical tool relative to virtual cutting boundaries or other virtual objects associated with the humerus and scapula to facilitate preparation of bone to receive a shoulder implant system. In some versions, planning for placement of a stemless implant component is based on a future location of a stemmed shoulder implant to be placed in the humerus during a revision surgery.

A rod template for determining a curvature and a length of a spinal rod used for joining vertebrae in a spine fusion surgery in advance includes a core, a transparent outer tube, and a transparent filler. The core is made of metal and includes a scale on a surface thereof. The outer tube is made of silicone rubber and covers the core. The filler is made of liquid silicone rubber and inserted in a gap between the outer tube and the core to fill the gap.

A method for assisting a user with surgical implementation of a preoperative plan includes generating a physical native tissue model of a native patient tissue. The physical native tissue model includes at least one primary patient tissue area including a surface of interest, at least one secondary patient tissue area including no surfaces of interest, and a base surface for engaging a supporting structure. The physical native tissue model, as generated, includes at least one information feature providing clinically useful information to the user. The information feature is substantially separated from the surface of interest. An apparatus for assisting a user with surgical implementation of a preoperative plan is also provided.

A system for making a proximal resection of tibia having localized anatomical surface features prior to resection, comprising: a resection guide locator including a body, the body including opposing medial and lateral wings extending outwardly from the body, the body defining a recess being a socket defined by an annular wall, the annular wall including an upper wall, a lower wall, a resection guide having a body defining a resection slot, at least a portion of the resection guide body sized and configured to be received within the recess defined by the resection guide locator.

A method of guiding a glenoid prosthesis is disclosed. The method includes pre-operatively determining a position and an orientation of a guide feature of a glenoid guide of the present disclosure based on a scapula of a specific patient, and engaging the glenoid guide with the scapula; and inserting a pin having an axis through the guide feature to or through the scapula.

A system comprised of custom radiographically designed tibial and talar cutting guides, a tibial reaming guide and bit, and instrumentalities for use in total ankle replacement surgery and a computer-based system and method for making the custom radiographically designed tibial and talar cutting guides.

Embodiments of the invention include devices and methods for implanting arthroplasty devices. Some embodiments include designs that allow for use of x-ray images as the only images used to fully and accurately preoperatively and intraoperatively size and align arthroplasty device components and prepare all necessary tissue.

A surgical kit and method for milling a bone, the surgical kit including: a rotatable milling tool including a receiving bore with an abutment portion; a positioning pin insertable in the bone for guiding the milling tool along a milling axis and towards the bone, the positioning pin including a pin shaft receivable in the receiving bore and a pin depth determination element, the pin shaft being abuttable against the abutment portion of the milling tool; and a bone milling guide positionable at a predetermined location on the bone for guiding the positioning pin when the positioning pin is inserted into the bone, the bone milling guide including a pin shaft guiding channel for receiving the pin shaft and a guide depth determination element cooperable with the pin depth determination element to provide an indication that the positioning pin is inserted in the bone at a predetermined depth.
