A computer visual guidance system for guiding a surgeon through an arthroscopic debridement of a bony pathology, wherein the computer visual guidance system is configured to: (i) receive a 2D image of the bony pathology from a source; (ii) automatically analyze the 2D image so as to determine at least one measurement with respect to the bony pathology; (iii) automatically annotate the 2D image with at least one annotation relating to the at least one measurement determined with respect to the bony pathology so as to create an annotated 2D image; and (iv) display the annotated 2D image to the surgeon so as to guide the surgeon through the arthroscopic debridement of the bony pathology.

Apparatus and methods for treatment of a bone. The apparatus may include an implant. The implant may include an implant tail and an implant head configured to expand, inside the bone, from a collapsed state to an expanded state. The apparatus may include an intramedullary rod defining a central longitudinal rod axis. The intramedullary rod may include a guide segment configured to guide the implant head into the bone and support the implant tail. The intramedullary rod may include an elongated extension member spaced radially apart from the central longitudinal axis. The extension member may be configured to provide clearance for the implant head as the implant head is advanced, in the collapsed state, into the bone. The extension member may be configured to provide clearance for the implant head in the expanded state.

The present application is directed a Joint Revision Surgery Apparatus which includes a blade guide block which has a plurality of blade guide slots and a central cavity. The blade guide block central cavity is positioned over the trunnion end of the existing prosthesis to be removed and secured to the prothesis. Straight, curved and compound curved knife blades are guided by the blade guide slots to cut the prothesis free. The securing of the guide blade block support apparatus against the femur is accomplished by the means of a male threaded T handle screw or male threaded eyebolt threading into one of the female threaded orifices in the blade guide block frame. The guide blocks in varying sizes and configurations, straight and curved knifes blades and related accessories may be sold as a complete kit. The Joint Revision Surgery Apparatus facilitates rapid, efficient and complete removal of an existing prosthesis during joint revision surgery.

Examples of an orthopedic surgical device for use in operating on a target bone and methods for operating a system for use in orthopedic surgery on a bone are generally described herein. An orthopedic surgical device can include an primary positioning block, and a secondary positioning component removably coupled to the primary positioning block. The secondary positioning component can be configured to: engage a prepared engagement feature machined into the target bone, and guide the primary positioning block to a predetermined position on a target bone. The orthopedic surgical device can include a first cutting block configured to: removably couple to the primary positioning block, and guide a cutting tool to cut the target bone.

A hip/shoulder prosthesis includes: a head component; a metaphyseal component; a diaphyseal nail, and a locking device. The head component includes: a front face and rear face; with a bore, and first and second shaped recesses in the rear face. The metaphyseal component includes: a central transverse aperture at an angle to the metaphyseal component's axis; a first end configured for threaded engagement within the bore of the head component; and a longitudinal hole that begins at the second end, transects the transverse aperture and reaches the first end, to receive the locking device. The diaphyseal nail is inserted in the femoral or humeral canal, and includes: fastening apertures that receive corresponding screws for fastening the diaphyseal nail to the femur or humerus; a portion configured to he received within, and engage, the transverse aperture of the metaphyseal component, and a transverse hole configured to receive the locking device.

The invention provides a femoral head centre of rotation locating device (10) comprising an adjustable frame (12) having a frame axis (X). The frame includes a central frame portion (14); a first jaw (16) that is linearly moveable relative to the central frame portion along the frame axis and having a first femoral head contacting surface (26); a second jaw (18) that is linearly moveable relative to the central frame portion along the frame axis and having a second femoral head contacting surface (28), and a gear wheel (32) mounted on the central frame portion. The gear wheel has a centric aperture (34) located substantially equidistant from the first and second femoral head contacting surfaces. The gear wheel is operably connected to each of the first and second moveable jaws by gear teeth (30) provided on a surface of each of the first and second moveable jaws. Linear movement of the first jaw in a first direction rotates the gear wheel to cause reciprocal linear movement of the second jaw to maintain the centric aperture at a position equidistant from the first and second femoral head contacting surfaces. This aligns the centric aperture with the native head centre of the femur as the first and second femoral head contacting surfaces come into contact with opposite surfaces of the femoral head.

A targeting kit comprises (i) a mounting arrangement for releasably mounting the targeting kit on an implant, (ii) first and second guide members having an elongate shape with a bore running along its longitudinal axis (iii) a holding arrangement for holding the first and second guide members, the holding arrangement being adjustable between a release condition, in which the positions of the first and second guide members are adjustable, and a holding condition, in which the first and second guide members are in a fixed position, and (iv) a bridging arrangement between the mounting arrangement and the first and second guide members, to space the first and second guide members with respect to the mounting arrangement, the bridging arrangement being adjustable between a release condition, in which the position of the mounting arrangement is adjustable, and a holding condition, in which the first and second guide members are fixedly spaced.
