Abstract: Certain aspects relate to a two-part surgical guide system for use in surgical procedures such as osteotomies. Certain aspects provide a first part including a contact surface configured to conform to a portion of an anatomy of the patient to substantially restrict movement of the first part with respect to the anatomy of the patient. The first part further includes guiding elements configured to receive reference pins and guide placement of the reference pins in the anatomy of the patient. Certain aspects further provide a second part, separate from the first part. The second part includes apertures. Each aperture is configured to receive a reference pin and substantially restrict movement of the second part with respect to the anatomy of the patient. The second part further includes a functional element for guiding a procedure on the anatomy of the patient.

Abstract: The orthopedic systems are patient-specific and provided with two types of features for positioning and/or fixing the plate to the bone or bone fragments. A method for generating bone plates comprises: generating a model of the bone defect or envisaged osteotomy based on one or more images of the bone and the surgical plan; designing based on said model a model corresponding to the envisioned repair of said bone defect/envisaged result of the osteotomy; generating a bone plate based on the information above, comprising: one or more patient-specific features corresponding to the surface of a bone fragment in the area close to the defect; and one or more fixation features whose position and/or orientation is such that the fixation elements will enter the bone in areas suitable for fixing the bone plate to each bone fragment.

Abstract: Drill alignment device (6) for use during the removal of bone cement (42) from a cavity (5) resulting from the removal of a cemented prosthetic device (3) from a long bone, such as a femur (2), during the revision of said prosthetic device, wherein the alignment device comprises an elongate body (61) having a size and shape for insertion in the cavity, wherein at least a part of the outer surface of said elongate body is complementary to the corresponding inner surface of said cavity, wherein the alignment device comprises a channel (7) extending through the elongate body between a proximal end (68) and a distal end (64) and wherein said channel is arranged and has a diameter suitable for receiving and guiding a reamer (8) arranged for removing bone cement in a distal part of said cavity
