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.

Two-part surgical guide

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.

Orthopedic bone fixation systems and methods

Method for making an orthosis of a body part of a person, wherein the method comprises of: &#x2014;measuring the body part with a shape and in a pose in order to obtain measurement data of the body part; &#x2014;correlating the measurement data of the body part to a predetermined statistical shape model of a corresponding reference body part in order to calculate parameters of the statistical shape model; &#x2014;digitally forming an orthosis model on the basis of the statistical shape model with the known parameters; &#x2014;producing the orthosis via a CAD/CAM system on the basis of the digitally formed orthosis model.
