A method for creating a patient-specific surgical plan includes receiving one or more pre-operative images of a patient having one or more infirmities affecting one or more anatomical joints. three-dimensional anatomical model of the one or more anatomical joints is created based on the one or more pre-operative images. One or more transfer functions and the three-dimensional anatomical model are used to identify a patient-specific implantation geometry that corrects the one or more infirmities. The transfer functions model performance of the one or more anatomical joints as a function of anatomical geometry and anatomical implantation features. surgical plan comprising the patient-specific implantation geometry may then be displayed.

An attachment for a drill includes an inner housing configured to be coupled to the drill. The attachment also includes an outer housing positioned at least partially around the inner housing. The attachment also includes a vertical guide coupled to or integral with the inner housing. The attachment also includes a horizontal guide coupled to or integral with the outer housing. The attachment also includes a guide adapter configured to move along the vertical guide and the horizontal guide. The inner housing and the vertical guide are configured to move vertically with respect to the outer housing and the guide adapter, and the inner housing and the guide adapter are configured to move laterally with respect to the horizontal guide and the outer housing.

A medical device and a method of using same are provided. The medical device includes a first arm and a second arm mounted on a support rail, each of the first arm and the second arm having a bone contacting region. The medical device also includes a mechanism for reducing a distance between the bone contacting regions hereby applying a force to a bone or bones positioned therebetween and a force gauge for indicating a force applied by the bone contacting regions.

An example physical targeting tool includes a main body defining a channel configured to receive a tool, the channel having a longitudinal axis; a first physical targeting feature attached to the main body; and a second physical targeting feature attached to the main body, wherein the first physical targeting feature and the second physical targeting feature are displaced along the longitudinal axis of the channel.

A minimally invasive precision cutting guide, targeting guide, implant, and other instruments comprise a system that permits a physician to surgically correct a bunion or similar deformity with a minimum disruption of surrounding soft tissue. The precision cutting guide ensures that the physician cuts bone in the proper location and orientation. Each of the instruments is designed to minimize disruption to surrounding soft tissue. The system also precisely locates an orthopedic implant such that it can fixate two bone fragments after an osteotomy, or two bones after surgery. The precision cutting guide, targeting guide, implant, and other instruments are provided in a sterile kit for the convenience of the surgeon and safety of the patient.

A surgical sheath system having a sheath with a hollow shaft; and a head coupled to and in fluid communication with the hollow shaft, the head having a first mounting feature for coupling a first surgical device; and a second mounting feature for coupling a second surgical device, the second surgical device being a different type of surgical device than the first surgical device.

A surgical guide assembly is disclosed herein that includes instruments configured to aid in the alignment of surgical instruments. In one aspect, a first and second instrument are provided that are configured to be connected to each other via interfaces and each define bone contact interface. The bone contact interfaces are configured to engage with the tibia and talus, in one embodiment.

A number of improvements are provided relating to computer aided surgery. The improvement relates to both the methods used during computer aided surgery and the devices used during such procedures. Some of the improvement relate to controlling the selection of which data to display during a procedure and/or how the data is displayed to aid the surgeon. Other improvements relate to the structure of the tools used during a procedure and how the tools can be controlled automatically to improve the efficiency of the procedure. Still other improvements relate to methods of providing feedback during a procedure to improve either the efficiency or quality, or both, for a procedure.

Disclosed are devices and methods for creating a bore in bone. The devices and methods described involve driving a rotating bit in an axial direction such that both rotation and linear movement are controlled and measurable. The instrument is useful for a surgeon to control and simultaneously measure the travel of the tool into the bone and prevent injury to surrounding structures.
