Next, the deformity detection module 422 may identify a reference axis 429 perpendicular with one of the center longitudinal axes 428a,b, such as center longitudinal axis 428b. The reference axis 429 may be at, or near, a joint between bones of the bone model 404. The deformity detection module 422 may determine that a deformity 426 exists if the center longitudinal axes 428a,b are not parallel or are not parallel when measured with a predefined margin for error. FIG. 7A illustrates a bone model 404 with a deformity 426. The deformity 426 is that the first metatarsal is not parallel, or not sufficiently parallel, to the second metatarsal at the joint between the first metatarsal and the medial cuneiform bones. Once the deformity 426 is determined, the deformity detection module 422 or apparatus 402 may determine what steps, procedures, devices, or instrumentation can be used to correct the deformity 426. The deformity detection module 422 may use a name, label, tag, or other identifier for a particular deformity 426.
