A system 100 or designing a surgical kit 700 for articulating surface repair in an anatomical joint of a patient is provided, which comprises at least one processor 120 configured to: determine damage to the anatomical joint; select, from a predefined set of implants having varying dimensions, the implant 300 that is the best fit for repairing the determined damage; select, from a predefined set of insert tools, the insert tool 720 corresponding to the selected implant 300; and design a contact surface 540 of a guide tool 500 to have a shape and contour that is designed to correspond to and to fit the contour of a predetermined area. This enables the use of standardized implants 300 that can be manufactured batch-wise, while still using an individualized guide tool 500 to ensure correct positioning of the implant 300. This helps ensuring that the implant will be positioned in the exact location of the determined damage.

A glenoid device for preparing a shoulder joint of a patient includes a reusable guide holder having a body between an upper surface and a lower surface and a bore passing through the body of the guide holder. The glenoid device also includes a patient-specific glenoid guide having a body with an upper and lower surface. The lower surface of the patient-specific glenoid guide is configured as a negative surface of a glenoid face based on preoperative image scans of the shoulder joint of the patient. The upper face of the patient-specific glenoid guide is configured to be coupled and contact the lower face of the guide holder, such that the bore of the guide holder is aligned along a patient-specific bore through the body of the patient-specific glenoid guide and along a corresponding alignment axis of the patient-specific glenoid guide.

An alignment guide includes a base, a swing arm for coupling to the base such that the swing arm is movable relative to the base, and a locking device for selectively fixing a position of the swing arm relative to the base. The base defines at least one first hole sized and configured to receive a first fixation element and defines at least one second hole sized and configured to receive a second fixation element. The swing arm extends from a first end to a second end. The second end of the swing arm including a coupling mechanism for coupling another guide to the second end of the swing arm. Methods also are disclosed.

Prosthetic device (10) for temporomandibular joint comprising a first prosthetic component (11), able to be associated with a mandibular condyle (112) of a patient, and a coordinated second prosthetic component (12), able to be associated with a respective glenoid fossa of the patient.

The present invention also concerns a guide device (35) for making an anchoring seating (113) for positioning the first component, and a prosthetic assembly comprising the prosthetic device (10) and the guide device (35).

The present disclosure involves object recognition as a method of registration, using a stereoscopic camera on Augmented Reality (AR) glasses or an endoscope as the image capture technology. Exemplary objects include surgical tools, anatomical components or features, such as bone or cartilage, etc. By detecting just a portion of the object in the image data of the surgical scene, the present disclosure may register and track a portion of the patient's anatomy, such as the pelvis, the knee, etc. The present disclosure also optionally displays information on the AR glasses themselves, such as the entire pelvis, the femur, the tibia, etc. The present disclosure may include combinations of the foregoing features, and may eliminate the need for electromagnetic, inertial, or infrared stereoscopic tracking as the tracking technology.

Devices and methods provided for joint arthroscopy contemplate and enable the provision of patient specific instruments (PSI). The devices and anatomical features of a patient are rendered adjustable by the provision of conforming surfaces and support elements to account for and enable repositioning of the anatomical features during surgery. Where the joint arthroscopy involves shoulder arthroplasty, a PSI system includes at least one shoulder PSI operable to be positioned on a bone in a shoulder in the patient. The at least one shoulder PSI allow for the transfer of preoperative planning to intra-operative procedures. The at least one shoulder PSI may be virtually designed as a model based on scan data of the bone in the shoulder of the patient. The at least one shoulder PSI may be fabricated based on the virtually-designed at least one shoulder PSI model.

The present disclosure is directed to a method of surgery, such as knee replacement surgery and hip replacement surgery that achieves optimal implant sizing and placement within a surgically repaired joint.

Provided is an apparatus and component parts of a system for the external fixation of bones. The component parts include fixation plates such as a C-shaped Plate, an N-shaped Plate, a J-shaped Plate, a K-shaped Plate, an I-shaped Plate, a Foot Plate, a Z-shaped Plate, a T-shaped Plate and an oval shaped Plate. Two or more fixation plates are configured along an axis, the two or more fixation plates; a plurality of telescoping adjustable struts that connect a first fixation plate along the axis with a second fixation plate of the plurality of fixation plates along the axis, wherein the first and second fixation plates are adjacent plates along the axis; and a plurality of posts, each post connecting two adjacent fixation plates of the plurality of fixation plates along the axis.

An instrument for navigating to a target area near a subchondral defect of a bone and associated methods are disclosed. The instrument can include a body portion having a patient specific surface defining a negative impression of a portion of a skin surface of a patient, and a targeting device coupled to the body portion, the targeting device including a rail and at least one device portal configured to guide a device into a subchondral region of the bone for treatment at the target area.

A cutting guide for guiding a cut in a radius, the radius being adjacent to an ulna, the cutting guide comprising: a cut guiding portion, an opposed ulnar mounting portion and a linking portion extending therebetween; the cutting guide being delimited by a cutting guide peripheral surface defining a bone facing portion, the bone facing portion being contoured to match the shape of the radius and ulna.
