The invention concerns a bone joining implant (1) for joining of a first bone section (2) with a second bone section (3) of a mammal bone (4) with a first attachment area (6), displaying several holes for fastening elements (5a), prepared for attachment to the first bone section (2), and a second attachment area (7), linked to the first attachment area (6), with the second attachment area (7) also displaying several holes for fastening elements (5b), also prepared for attachment to the second bone section (3), with formation of a separating tool guidance contour (9) between the first and second attachment areas (6, 7), defining a cutting line (8), as well as a procedure for the individualized manufacture of such a bone joining implant (1).

A surgical template system for use in working on a bone comprises: a tool guide block comprising at least one guide aperture for receiving and guiding a tool to work on a bone; locating means comprising a plurality of locating members, each member having a respective end surface for positioning against a surface of the bone; and attachment means for non-adjustably attaching the tool guide block to the locating means such that, when attached, the member end surfaces are secured in fixed position with, respect to each other, for engaging different respective portions of the surface of the bone, and the at least one guide aperture is secured in a fixed position with respect to the end surfaces. Corresponding methods of manufacturing a surgical template system, methods of manufacturing locating means for a surgical template system, methods of fitting a prosthesis to a bone, surgical methods, and surgical apparatus are described.

A bilateral hearing implant surgical template arrangement is described. An adjustable headpiece with left and right sides fits over the head of a surgical patient. There are left and right implant stimulator templates, each configured to conform against an underlying side of the patient's head and each connected to a corresponding left and right side of the adjustable headpiece by an adjustable connection. Each adjustable connection is configured to allow adjustment of the position of the implant stimulator template with respect to the adjustable headpiece so as to define stimulator implantation sites at symmetric locations on each side of the patient's head.

A method of fabricating a customized patient-specific guide block is disclosed. The method includes generating a image of a patient's bony anatomy and an implanted prosthetic component secured to the patient's bony anatomy, identifying landmarks on the patient's bony anatomy and the prosthetic component, selecting a revision surgical instrument based the image and the landmarks, and manufacturing the customized patient-specific guide block including a customized prosthesis-specific negative contour shaped to match a corresponding contour of the implanted prosthetic component.

An acetabular guide system for placing a guide pin near an acetabulum, includes a patient specific acetabular guide including an interior surface and an exterior surface, the exterior surface being configured to have a geometry to register within the acetabulum of a specific patient, a first drill insert configured to be received by the guide at a first location, the first drill insert having a first longitudinal bore configured to be received concentrically in a guide bore of the guide, the guide bore extending exterior to the interior surface, a second drill insert configured to be fixed to a boney portion exterior to the acetabulum at a second location a predetermined distance from the first location, the second drill insert forming a second longitudinal bore, and a selectively removable alignment pin configured to be received by at least one of the first longitudinal bore and the second longitudinal bore.

A number of orthopaedic surgical instruments are disclosed. A method, apparatus, and system for fabricating such instruments are also disclosed.

Provided herein is a method for generating and manufacturing a surgical guide for guiding a surgical intervention on a bone of a patient, and surgical guides obtainable by said method. The guides provided herein comprise an anatomy engagement surface or contact points for contacting with the first bone, and further comprise a support surface configured for contacting a second bone of the patient, over a certain range of motion of said second bone.

Disclosed herein are methods, compositions and tools for repairing articular surfaces repair materials and for repairing an articular surface. The articular surface repairs are customizable or highly selectable by patient and geared toward providing optimal fit and function. The surgical tools are designed to be customizable or highly selectable by patient to increase the speed, accuracy and simplicity of performing total or partial arthroplasty.

A method of preparing a distal femur for a knee joint implant includes mounting a patient-specific bone engagement surface of a femoral alignment guide on a complementary surface of a distal femur of a patient. A plurality of alignment pins is inserted through a corresponding plurality of guiding bores of the femoral alignment guide into the distal femur. A cutting guide is mounted on first and second alignment pins of the plurality of alignment pins, and a first resection of the distal femur is made using the cutting guide while cutting through the femoral alignment guide.

The device comprises a clamp secured to a cutting guide (4) and comprising two arms (1) and (2) articulated against an elastic return means (3). According to the invention, the device comprises a bespoke volumetric body (5) acting as a spacer, being shaped such as to be coupled to one of the arms (2), one of the 10 faces of the body (5), considered to be opposite to the coupling with the arm (2) has a recessed indentation that is married, in inverted form, with the posterior articular face of the patella positioned on the other arm (1), said indentation and the height of the volumetric body (5) being defined by means of form modeling software using scanner or MRI data from said patella, in order to give the 15 orientation and positioning of the prosthetic patella, the posterior cutting height and the drilling depth of a retention pin for the patellar implant, the volumetric body (5) acting as a spacer being coaxially drilled with a through hole of a diameter that is substantially equal to that of the patellar implant retention pin.
