—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; —digitally forming an orthosis model on the basis of the statistical shape model with the known parameters; —producing the orthosis via a CAD/CAM system on the basis of the digitally formed orthosis model. ## Claims ### Claim 1 A method for making an orthosis of a body part of a person, the method comprising: measuring the body part with a shape and in a pose in order to obtain measurement data of the body part; 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; digitally forming an orthosis model on the basis of the statistical shape model with known parameters; and producing the orthosis via a CAD/CAM system on the basis of the digitally formed orthosis model, and wherein the method is preceded by the following steps of: selecting a plurality of reference persons, such that a shape of the reference body part of multiple reference persons differs; making a plurality of digital scans of the reference body part for each of the plurality of reference persons, wherein the reference body part is placed in multiple predetermined poses for making multiple ones of the plurality of digital scans; and constructing a statistical shape model on the basis of the digital scans. ### Claim 2 (depends on 1) The method as claimed in claim 1, wherein the digital scans have an information density which is considerably greater than the information density of the measurement data. ### Claim 3 (depends on 1) The method as claimed in claim 1, wherein the statistical shape model is further provided with predetermined anatomical and/or biomechanical zones to which predetermined orthosis properties have been allocated, chosen from: high strength, low strength, ventilation and reduced pressure, such that during the step of digitally forming an orthosis model the predetermined orthosis properties are applied at the position of corresponding zones of the statistical shape model. ### Claim 4 (depends on 1) The method as claimed in claim 1, wherein the CAD/CAM system is a 3-D printer. ### Claim 5 (depends on 1) The method as claimed in claim 1, wherein the measuring of the body part comprises of taking a plurality of photos of the body part, wherein the plurality of photos comprise predetermined sides of the body part. ### Claim 6 (depends on 1) The method as claimed in claim 1, wherein the body part is chosen from wrist, elbow, ankle, knee and back. ### Claim 7 (depends on 1) The method as claimed in claim 1, wherein the statistical shape model comprises a plurality of rotation axes which are related to predetermined anatomical and/or biomechanical features of the reference body part. ### Claim 8 (depends on 1) The method as claimed in claim 1, wherein the step of measuring the body part further comprises of marking predetermined anatomical points, such that the measurement data comprise information about the location of the predetermined anatomical points, and wherein the statistical shape model further comprises reference information about the location of the predetermined anatomical points on the reference body part. ### Claim 9 A system for making an orthosis of a body part of a person, the system comprising: a first measuring device for measuring the body part with a shape and in a pose in order to obtain measurement data of the body part; a digital processing unit for 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; a digital forming unit for digitally forming an orthosis model on the basis of the statistical shape model with the calculated parameters; and a CAD/CAM system for producing the orthosis on the basis of the digitally formed orthosis model, wherein the predetermined statistical shape model is formed by selecting a plurality of reference persons such that a shape of the reference body part of multiple reference persons differs and by making a plurality of digital scans of the reference body part for each of the plurality of reference persons, wherein the reference body part is placed in multiple predetermined poses for making multiple ones of the plurality of digital scans, and constructing a statistical shape model on the basis of the digital scans, wherein the first measuring device has an information density which is considerably smaller than the information density of a second measuring device with which the plurality of digital scans of the reference body part were made. ### Claim 10 (depends on 9) The system as claimed in claim 9, wherein the CAD/CAM system is a 3-D printer.
