A surgical device includes a first body component including at least one insert embedded therein and a second body component including a patient-specific surface. The first body component includes a first material and the at least one insert includes a second material. The first body component defines at least one first hole and the second body component defines at least one second hole. The second body component is configured to be coupled to the first body component such that the at least one first hole and the at least one second hole are aligned when the first body component is coupled to the second body component to define at least one continuous fixation hole sized and configured to receive an elongate fixation device at a predetermined location.

Multi-modal patient-specific surgical guides

A medical device has a guide locator and a guide element. The guide locator has a mount body having a conformal surface that is shaped to be complementary to a natural anatomical surface of a patient bone and defining a mount receptacle. The mount body defines a guide receptacle. The guide element includes a guide body having a shape configured to fit with to attach the guide receptacle of the guide locator and a guide slot formed in the guide body. The guide slot includes at least one opening for receiving a tool therethrough. A retention mechanism is configured to hold the guide element within the guide receptacle of the guide locator.

Modular guide system for surgical procedures

A guide for use in cutting a bone is disclosed. The guide includes a bone contacting surface contoured to conformably mate with a first bone surface when placed against the first bone surface, and a guide surface that is spaced apart from the bone contacting surface. At least one prescribed patient-specific depth of cut information is provided on the guide surface that corresponds to the desired depth of cut being made using the guide.

Surgical guide with cutting depth information

A system includes a first tool having a base, a nut, and a tool guide. The base extends from a first end to a second end and includes at least one thread disposed along a length thereof. The first end includes a foot having a widthwise dimension that is greater than a diameter of the at least one thread. The nut is configured to be disposed along the length of the base and to engage at least one thread. The tool guide is configured to be slideably disposed along the length of the base and has a body including a flange portion. The flange portion defines an opening for receiving at least one of a pin and a cutting tool. Rotation of the first nut causes the nut to translate along the length of the base thereby causing the tool guide to move along the length of the base.

Minimally invasive tools, systems and methods

Alignment systems and methods are disclosed. A system includes a first component and a second component. The first component has a first body supporting a first alignment member. The second component has a second body supporting a second alignment member. The first and second alignment members are separated from another and are configured to provide an indication that a fluoroscopic device is properly aligned with an anatomical plane when viewed under fluoroscopy. A method includes placing a first component supporting a first alignment member and a second component supporting a second alignment member relative to a patent, and aligning a fluoroscopic device with an anatomical plane using the first and second alignment members.

Alignment systems and methods

A system includes a first spacer sized and configured to be received within a resected bone space of a first bone and a second spacer sized and configured to be coupled to a second bone. The first spacer and the second spacer each include a body extending between a bone contacting surface and a coupling surface. At least one shim is positioned between the first and second spacers. The shim includes a body extending between a first coupling surface and a second coupling surface. The first spacer, the second spacer, and the at least one shim position the first and second bones in a predetermined alignment. An adjustable guide including a guide adapter and a guide body is configured to couple to the first spacer and is adjustable on a first axis.

Joint osteotomy system and method

An example method includes registering, via a visualization device, a virtual model of a portion of an anatomy of an ankle of a patient to a corresponding portion of the anatomy of the ankle viewable via the visualization device, the virtual model obtained from a virtual surgical plan for an ankle arthroplasty procedure to attach a prosthetic to the anatomy. The example method also comprises displaying, via the visualization device and overlaid on the portion of the anatomy, a virtual guide that guides at least one of preparation of the anatomy for attachment of the prosthetic or attachment of the prosthetic to the anatomy.

Virtual guidance for ankle surgery procedures

A resection guide includes a first body portion and a second body portion. The first body portion has a first bone engagement structure and defines a first plurality of holes. The second body portion has a second bone engagement structure and defines a second plurality of holes. The first body portion and the second body portion are operable to separate a first anatomical structure of a patient and a second anatomical structure of the patient. A cutting guide defines at least one guide aperture that is operable for guiding a cutting tool for use in resecting a portion of the second anatomical structure of the patient. The cutting guide is positionable relative to the first body portion.
